The Unnamed Glen

At 04:00 on Wednesday, 29 July 2026, the telephone rang and dragged me out of sleep. Only a handful of people had that number, and none of them ever called with good news.

"Mercer," I answered, already reaching for the bedside lamp.

"Andy, it's Alastair Reid at the Cairngorms."

The Cairngorms National Park Authority area operations manager sounded controlled, but there was strain beneath the professional tone.

"We've got a situation. Chloe Bennett, twenty-three. She's missed her Tuesday evening safety call and there's been no confirmed contact with her for three days."

I sat up and rubbed the sleep from my eyes.

"Where did she go missing?"

"The northern restricted area. The Unnamed Glen."

My hand stopped on the lamp switch.

The Unnamed Glen.

Wardens did not talk much about that part of the park, at least not officially. It covered roughly 200 square kilometres of remote mountain, Caledonian pinewood, peat bog and hidden corries. The maps showed boundaries, contour lines and little else.

"Her Land Rover Discovery is still at the Linn of Dee walkers' car park," Alastair continued. "She left a route card at the information point on Friday morning, 24 July. Planned a five-day solo hillwalking circuit. A friend raised the alarm when she missed last night's call."

"Walking alone, despite the guidance?"

"Every route notice makes it clear that solo crossings aren't advised. She knew the risks."

I did not say what we were both thinking. Knowing the risks rarely stopped anyone who believed preparation would be enough.

I took a notepad from the bedside table.

"Weather?"

"That's the other problem. An Atlantic low is driving east across the Inner Hebrides and into the Highlands. You've perhaps thirty-six hours before the worst of it, but the front is accelerating."

"I'll assemble the team. Has anyone been in already?"

"The regular mountain-rescue personnel and wardens swept the principal paths yesterday. Local gamekeepers checked the stalkers' tracks they could reach. Nothing. That's why I'm calling you. Your lot have the experience for that terrain."

"Send me everything you've got. We'll aim to lift by 07:00."

I ended the call and began ringing numbers. Ewan MacLeod first. We would need his tracking skills from the outset. Then Martin Shaw, our medic, Gareth Price on communications, and Colin Fraser, the HM Coastguard pilot attached to us for the operation. Each conversation was short. We had worked together too often to need lengthy explanations.

While dressing, I opened the weather display on my tablet. Alastair had not exaggerated. The Atlantic system was strengthening as it crossed the Inner Hebrides, its leading edge already pressing into the western Highlands. We had a narrow window in which to find Chloe before the conditions became dangerous enough to halt both flying and ground movement.

The Unnamed Glen was among the most beautiful and treacherous places I had ever seen. Mountains rose abruptly above ancient pinewood. Burns vanished into peat and reappeared at the foot of scree slopes. Hidden corries and narrow clefts could swallow a person within metres of a path.

Most visitors never approached it. Officially, the area was restricted because it was ecologically sensitive, hazardous and deliberately left undeveloped.

The unofficial explanation lay in its history.

People disappeared there. More than weather, accidents and statistics could comfortably explain. Years earlier, a senior warden had told me that local staff had stopped assigning informal names to paths and features inside the glen because every name eventually ended up in a missing-person report.

I packed with the efficiency of habit: additional layers, emergency shelter, first-aid kit, GPS receiver loaded with OS mapping, satellite communications, three days of rations, water-treatment equipment, marine distress flares and the technical gear we might need for a difficult casualty recovery. The team also carried high-output deterrent spray under specialist operational authority. Everything went into a rucksack I could carry for days if necessary.

At 06:30 I arrived at the specialist Highland rescue coordination base near Aviemore. Ewan's vehicle was already outside. That did not surprise me. In the seven years we had worked together, I had never reached a briefing before him.

The building was quiet, occupied mainly by night staff completing reports. I went straight to the ready room and found Ewan studying an OS map spread across the table.

"Morning, Andy," he said without looking up.

His finger followed the line of a burn descending from a broad ridge.

"No confirmed contact for three days in that country. Not good."

"No, it isn't."

I set down my rucksack and stood beside him.

"What's your reading?"

Ewan had spent most of his life tracking. He had begun with deer while working on Highland estates, then turned to missing people after joining mountain rescue. He noticed disturbances in ground and vegetation that most of us would have walked over without seeing.

"If she kept to her planned path on the first day, she'd have reached this ridge by evening." He tapped a point about 13 kilometres from the Linn of Dee car park. "After that, there are three likely choices if she left the route. This glen gives the most shelter. The ridge has the best views. The burn offers water and something easy to follow."

The door opened and Martin entered with his personal rucksack and the larger medical pack he took on every call-out.

"What have we got?" he asked, setting both down carefully.

"Twenty-three-year-old woman. Missed her safety call last night and no confirmed contact for three days. She's on the fifth day of a solo circuit somewhere in the restricted northern area."

Martin's expression tightened.

"Weather?"

"Atlantic front coming in fast. We're against the clock."

Gareth arrived next, already checking his equipment. He carried more electronics than the rest of us combined: mountain-rescue radios, satellite handsets, signal boosters, GPS trackers and protected spare power packs.

"I've got her last mobile connection," he said, taking out his tablet. "The handset stopped reporting on Friday evening, but I've got an approximate grid reference. I've also checked her public walking posts on Instagram and her route profile on the navigation app. She's experienced. About three years of documented trips."

Colin came in last with the aviation briefing in his hand.

"The S-92 is fuelled and ready at the Inverness-area base. Winds are acceptable for the moment, but we need to be on the ground before midday. After that, the gusts may make a landing or safe lift from the glen impossible."

I looked at the four men around the table. I trusted each of them with my life, and on more than one occasion I had done exactly that. Together we formed a specialist Police Scotland mountain-rescue team working with Cairngorms National Park Authority staff and HM Coastguard aviation support.

"Right," I said. "Let's go through what we know. Chloe Bennett, twenty-three, experienced, but travelling alone against the published guidance. Her Land Rover is still at Linn of Dee. She registered on Friday, 24 July, for a five-day solo hillwalking circuit. She's missed her Tuesday evening call and has had no confirmed contact for three days. The front coming in from the west limits our search window."

"What sort of experience?" Ewan asked.

Gareth opened her route profile.

"Several multi-day walks in Snowdonia, the Lake District and the Yorkshire Dales. This appears to be her first solo Cairngorms crossing."

"Proper kit?" Martin asked.

"The route card gives her rucksack weight as 18 kg," I said, consulting Alastair's message. "That suggests she was carrying enough."

"Eighteen kilos is still fairly lean for five days alone," Ewan said. "Either she packed carefully or left out something important."

"Any medical conditions?" Martin asked.

I shook my head. "None on the online emergency-contact details."

"The ordinary search teams have covered the main paths?" Colin said.

"Yesterday. No sign."

We completed the briefing while transferring our kit for the road journey to the aviation base. The team had four compact tents. Ewan, Martin and Colin each carried one; Gareth and I would share the fourth when watch arrangements allowed either of us to rest.

By 07:15 our equipment was secured inside the HM Coastguard Sikorsky S-92. The sun had only just cleared the eastern mountains, casting long shadows across the land.

"Updated forecast," Colin called from the cockpit as we strapped in. "The wind is strengthening earlier than expected. It will be rough, but still within limits."

The rotors gathered speed, their beating becoming a deafening roar as we lifted away. Aviemore and the surrounding roads shrank beneath us, giving way to forest, moor and the distant mass of the Cairngorm plateau. Colin turned north-east before following the safer approach towards the search sector. Loch Morlich caught the early light below us, bordered by dark pinewood beneath the northern edge of the plateau.

Farther into the mountains, the country became harsher. I watched the ground and tried to imagine the choices a lost hillwalker might make. The Unnamed Glen lay ahead, less visited, poorly mapped and somehow more oppressive than the surrounding wilderness.

I had never told the team how uneasy it made me. They were professionals. We worked with evidence, terrain and probability, not feelings. Yet something about that glen had always seemed wrong.

"Andy," Gareth said over the headset. "I've got Alastair on the radio."

I adjusted my microphone.

"Alastair, we're about twenty minutes from the landing site. Any change?"

His reply crackled through the headset.

"Nothing new. Wardens are maintaining a presence at Linn of Dee in case she returns under her own steam. The weather is deteriorating faster than forecast. You may want to consider -"

"We're going in," I said. "She's already missed three nights of contact."

"Understood. Just be aware that you may be stuck there if the front accelerates."

"Noted."

I looked around the cabin. Nobody appeared troubled by the warning. All of us had worked operations in which weather made extraction impossible. It was part of the job, though never a part to be treated casually.

"Five minutes," Colin announced. "I've got the clearing. Tight approach, but manageable."

I leaned towards the window. There were no roads, buildings or mobile masts below us. Only mountain, pinewood, exposed rock and the darker folds of corries stretching away in every direction.

If Chloe was injured or lost there, her chances diminished with every passing hour.

The S-92 descended towards a clearing just large enough to accept it. Colin worked the controls with the precision of long experience, compensating for wind curling unpredictably around the slopes. As we dropped lower, I saw dark cloud massing over the western horizon.

The front was already visible, a grey wall advancing across the mountains. The forecast had underestimated its speed.

"That looks unpleasant," Martin said over the intercom.

"All the more reason to move," I replied.

The aircraft settled with a gentle jolt. We unloaded while the rotors continued turning, then moved clear. The air smelt of wet Scots pine and approaching rain.

Colin monitored the wind and shut the engines down. The sudden silence was almost as shocking as the noise had been.

"I'll secure the aircraft," he said, reaching for the tie-down equipment. "Those clouds are arriving too quickly. If the gusts keep building, I won't be able to lift safely."

Ewan was already studying the ground beyond the landing area. Gareth established a radio schedule with the coordination base and Police Scotland control at Inverness, checked satellite connectivity and transmitted the landing grid reference. Martin organised the medical equipment for whatever condition we might find Chloe in.

If we found her at all.

I stood at the edge of the clearing and looked into the country that had swallowed her. Somewhere among those kilometres of forest, peat and rock, a young woman might be waiting for rescue.

Or she might not.

A distant roll of thunder reached us as we finished our preparations.

I checked my GPS, radio and pack fastenings, then turned to the others.

"Standard search procedure. Ewan, take point and look for any trace of Chloe. Gareth, maintain radio contact while the terrain allows it. Martin, keep the medical kit ready. Colin, finish securing the aircraft and join us as soon as you can."

The wind rose again while Colin tested the tie-downs. A warning illuminated on his handheld weather display. He watched it for several seconds, then shook his head.

"That's the flying window gone. I can't lift safely in this, and it will be worse by the time I complete the start-up checks."

He reported the grounded aircraft to control, confirmed that the S-92 was secured and gave its precise grid reference. Headquarters acknowledged that extraction by air was no longer available and placed road-based resources on notice in case the weather remained unsuitable.

Colin shouldered his rucksack and joined us.

Ewan moved away from the landing site, his gaze fixed on the ground. The rest of us followed at intervals to avoid destroying any marks he found. The main path was initially well worn, but soon narrowed as the forest pressed in from either side.

Pine needles softened our steps. Apart from gusts moving through the canopy, the woodland was unnaturally quiet. Moisture burdened the air.

"Found something," Ewan said after about twenty minutes.

He crouched at the edge of the path and touched the ground lightly.

"Boot print. Woman's walking boot. Likely UK size five. Pattern and length fit Chloe's details."

I knelt beside him. The print lay clearly impressed in a patch of wet earth. Its tread was good quality and showed little wear.

"Her route card says Scarpa Terra boots, UK size five."

Ewan nodded. "That's consistent. She was still following the mapped path here."

We continued at his pace while he tracked increasingly faint signs of Chloe's passage. The wind bent the tops of the pines and shook loose a shower of needles. The storm was accelerating exactly as Alastair had warned.

Ewan stopped where the path curved around a large boulder. He examined the ground, stepped into the undergrowth and studied a broken stem on a low shrub.

"She left the path here," he said. "Deliberately. It wasn't a stumble or a navigational mistake."

"Why leave the recognised route?" Gareth asked, glancing between his GPS and the OS mapping.

Ewan moved several metres into the trees before answering.

"Her stride lengthened. The toe impressions are deeper. She began moving faster."

"Running?" I asked.

"Not quite. Hurrying."

He advanced again, following indications invisible to the rest of us.

"Something made her uncomfortable enough to abandon the path and quicken her pace."

We followed him through undergrowth that thickened with every step. The pinewood was old, with massive trunks rising more than 30 metres above a deep carpet of fallen needles. Ewan held a straight line and occasionally showed us what he was using: a snapped twig, a scuff on dead wood, moss disturbed on a fallen trunk.

After roughly an hour, the trees opened around a small clearing. Ewan circled it slowly.

"She stopped here. Put her rucksack down and sat on this log for a while."

He indicated a smooth section of fallen pine where the moss had been compressed.

Martin surveyed the clearing.

"Reasonable place to rest. Clear views in every direction. Easier to defend than the surrounding woodland."

A chill passed through me that had nothing to do with the wind.

"Defend against what?"

Ewan did not answer. He was studying the dense trees on the far side.

"She left that way. Still moving quickly."

The sky darkened as cloud rolled over us. Lightning lit the forest for an instant.

"How far from the final mobile connection?" I asked.

Gareth checked his receiver.

"Less than two kilometres. The estimate places it ahead of us."

We pressed deeper into the pinewood. The undergrowth thinned, making the trail harder to read, but Ewan did not hesitate.

Two hours after leaving the aircraft, the trees opened around another clearing. Martin gave a low whistle.

"There."

A splash of rust-orange hung against the green and brown of the forest. A Berghaus rucksack was suspended from a low pine branch at the clearing's edge, about 1.5 metres above the ground. It was too high to have been dropped there. Someone, or something, had placed it deliberately.

I approached with care. The brand, colour and model matched Chloe's route profile.

"It's hers."

I lifted it down. It felt far too light.

"Something's wrong."

Martin joined me as I laid it on a groundsheet and opened the main compartment. Inside were a lightweight tent, a dark green sleeping bag, cooking equipment, dehydrated expedition meals and oat bars from an outdoor shop, a water filter, first-aid kit and spare clothing. It was everything a properly equipped hillwalker ought to have carried, and much of it appeared unused.

"Her survival kit is all here," Martin said. "Why would she leave it?"

"Perhaps she didn't choose to."

Gareth searched the side pockets.

"Her journal's here. Camera as well."

He removed a weather-sealed Pentax compact camera and switched it on. The screen lit immediately.

"The battery's still charged. Last photograph was taken yesterday afternoon. There are dozens from the walk."

In the lid compartment I found a laminated OS map, a compass, waterproof matches and a worn knitted puffin keyring. The little bird had been repaired more than once, its coloured wool faded from handling. It was the sort of keepsake someone carried for luck or comfort.

I set it carefully aside.

"Show us the photographs."

Ewan and Colin joined us while Gareth worked through the images. The early pictures were ordinary walking photographs: broad views of ridges, close studies of wildflowers, and self-portraits from high ground. Chloe had auburn hair tied back and the assured expression of someone comfortable outdoors.

"Nothing troubling here," Gareth said. "These match the planned route."

The sequence continued through her first day and night: sunset over the hills, dew on a spider's web, her small camp arranged neatly beside the path.

The photographs changed during the second day. They became less carefully framed and more hurried. There were fewer recognisable landmarks and more apparently random views into the trees. Several were blurred or tilted as though taken while she was moving.

"Wait," I said. "Go back one."

Gareth returned to a photograph of dense pinewood. At first it showed only trunks, shadow and undergrowth.

"In the background. Between those two pines."

He enlarged the area. The image broke into grain, but a large dark shape remained visible behind one of the trees. It was impossible to identify, though clearly substantial.

"Could be anything," Colin said. "A deer in shadow, perhaps."

"Or a large dog," Gareth said, without conviction.

He continued. The next pictures showed similar forest, their framing increasingly erratic: blurred ground, canopy, and empty spaces between trunks, as though Chloe had been turning and taking photographs without time to aim.

Then a night image appeared. Her flash had illuminated a small clearing much like the one in which we stood. At the extreme edge of the frame, barely reached by the light, were two pale reflective points.

"Eye shine," Ewan said. "Something watching from the tree line."

"Too high for a deer or dog."

The points were more than 2 metres above the ground.

The final series showed Chloe's camp. Her rust-orange tent was pitched close against a rock face, as if she had wanted to keep one side protected. Her cooking equipment lay in order. The last image had been taken from inside the tent, looking through its mesh towards the forest at dusk. Nothing was immediately visible beyond trunks and deepening shadow.

"That's the last one," Gareth said. "Timestamp is 19:42 on Tuesday, 28 July 2026."

Silence settled over us.

The rucksack hung deliberately from a branch. The frantic photographs. Something large following her through the trees.

"Search the clearing," I said. "Martin, look for blood or evidence of a struggle. Gareth, copy every image to the tablet and start on the journal. Colin, scan the perimeter with binoculars. Ewan, find where her trail leaves this place."

They moved without question. I began a systematic search for missing equipment or any indication of what had happened. The wind strengthened and thunder sounded again, much closer.

"Andy," Ewan called from the far side of the clearing. "You need to see this."

I crossed to him. He had pushed aside low growth about 45 metres from the rucksack, exposing soft earth. The others gathered around us.

An impression lay in the mud unlike anything I had seen in fifteen years of search and rescue. It was vaguely foot-shaped, but 46 cm long and pressed so deeply into the ground that whatever made it must have carried immense weight. Five distinct toe marks spread across the front, each ending in a claw-like gouge.

"What in God's name made that?" Colin said softly.

Ewan shook his head. "Nothing I've ever tracked."

Martin crouched and placed his hand beside the print. It looked absurdly small.

"This isn't from any ordinary animal. A wild boar doesn't leave anything like it. Neither does a large dog, and the shape is wrong for a bear."

"Could somebody have faked it?" Gareth asked. "Something intended to frighten walkers?"

Ewan pointed to the depth and the clean sides.

"Whatever made it put hundreds of kilograms through that foot. Look at the edges. It's recent, within the last day."

My stomach tightened as I studied the splayed toes and the claw marks, which extended several centimetres beyond them. I had spent my working life in these mountains. I knew the tracks of red deer, wild boar, pine martens, dogs and every other credible Highland animal. Even the footprint of a brown bear, had one somehow been loose in modern Scotland, would not have looked like this.

"There's another," Ewan said.

A similar mark lay nearly 2 metres ahead, half hidden beneath ferns. Another followed it.

The trail went in the same direction Chloe had taken.

"It was following her," I said.

Thunder broke almost overhead, making all of us flinch. Heavy drops began striking the canopy.

"We need shelter," Colin said, looking up. "This is about to become severe."

I looked from the enormous print to Chloe's rust-orange rucksack and the faded knitted puffin. I thought of the photographs, the dark mass among the trees and the high reflective eyes.

"Pack everything," I said. "We follow these tracks while they're still visible. The rain will erase them within minutes."

For a time we remained gathered around the footprint, nobody speaking. Rain tapped through the branches, growing heavier by the second. The storm we had tried to outrun had reached us, and it was already destroying the evidence.

"Document it first," I said. "Gareth, photographs with a scale."

He took out a waterproof camera and laid a 15 cm rule beside the impression. His hands were not quite steady. The rule looked insignificant next to the 46 cm print.

"What about the others?" Martin asked, indicating the line Ewan had found.

"Every one we can reach."

Ewan advanced carefully along the trail while Gareth photographed each impression. I returned to Chloe's rucksack. Something still made no sense. An experienced hillwalker frightened enough to leave the recognised route might abandon spare clothing, but not her shelter, sleeping bag, food and water filter unless she had been given no choice.

"Let's search it properly again," I told Martin. "There may be something we've overlooked."

We knelt beside the rucksack and shielded it from the increasing rain. Martin emptied the main compartment methodically while I checked each smaller pocket. My fingers found a leather-bound object in an outer sleeve.

"Here."

I drew out a small brown journal. Its cover was worn and its pages were waterproof, the kind sold in any decent outdoor shop.

"That could help," Martin said. "A lot of walkers keep daily notes."

The first pages were written in neat, level handwriting, recording distance, wildlife and weather.

The entry for Friday, 24 July 2026, read:

"Made good time from Linn of Dee. Perfect weather. Saw three red deer at the burn crossing. Met a couple coming out who said the ridge views are worth tomorrow's climb. Camped near route marker eight. Feeling great."

The next was dated Saturday, 25 July 2026:

"Reached the ridge by midday. Views even better than expected. Taking far too many photos. Something odd happened at sunset. Heard voices calling from the glen below, but couldn't see anyone through the binoculars. Probably sound carrying strangely. Making good progress."

Martin looked over my shoulder.

"Ordinary enough so far."

I turned the page. The handwriting in the next entry was less controlled.

"Sunday, 26 July 2026. Woke feeling watched. Probably nothing. Left the main path to look into the eastern corrie. More remote, but beautiful. Camped early against a rock face for shelter from the wind. Heard the voices again last night. They sounded as though they were saying my name. Not animal calls. Checked the area but found nobody. Taking a different route tomorrow."

The entry for Monday, 27 July had been written with such force that the pen had almost cut the paper.

"Something is following me. Found trees with bark stripped away in long scratches. Far too high for any bear, more than 2 metres up. Tried to tell myself it meant nothing, but I keep seeing movement in the trees. Big and dark. I'm storing food properly and making noise. Doing everything you're meant to do. This doesn't feel like an animal encounter. Taking photographs when I can. Moving camp every few hours. I don't know which direction is safe."

The final entry was dated Tuesday, 28 July 2026. The writing slanted across the page in jagged lines.

"It isn't an animal. It walks on two legs sometimes. I can hear it breathing outside my tent. I think it's learning my routine. I have to keep moving."

There was nothing after that.

I closed the journal. The cold I felt had nothing to do with the rain.

"Gareth. Ewan. Come here."

They joined us beneath the inadequate shelter of a pine while I read the entries aloud. Gareth grew pale. Ewan's expression hardened into something between concern and determination.

"The photographs," he said when I finished. "We need to examine them again in light of this."

Gareth opened the copies on his tablet.

"I can enhance some of the later ones."

He selected the blurred photographs that had first appeared random. On the larger screen, with the contrast adjusted, details emerged that the camera display had concealed.

"That one," Martin said. "Upper right."

Gareth enlarged a patch of dense woodland. Between two trees, partially hidden in shadow, stood a dark figure. It appeared upright, balanced on two legs. Its proportions were wrong. The arms hung beyond where its knees should have been.

"That isn't a deer," Colin said. "And it isn't a bear."

Gareth opened another image taken near dusk. The low light made it coarse, but the shape moving between the trees was unmistakably tall and bipedal, with an awkward gait that no person would willingly adopt.

"Try this one," Ewan said.

The picture showed a pine trunk stripped by long parallel gouges. Chloe had held one hand within the frame for scale. The damage began more than 2 metres above the ground and continued upwards.

"Nothing local makes marks like that at that height," Ewan said.

I indicated another photograph. "And this?"

It was a close view of a print in mud beside a burn, less distinct than the one near us but recognisably the same form.

"She was collecting evidence," I said. "Even frightened, she kept documenting it."

Thunder cracked overhead. Rain became a sustained downpour, water running into the print and softening its edges.

"We move now," I said. "Gareth, take her belongings. Ewan, can you continue tracking in this?"

He studied the impressions as they began to collapse.

"For a while. Something that heavy leaves more than surface marks."

"Direction?"

He pointed into the forest, away from every recognised path.

"Northwest. Same line as Chloe's boot marks."

"Then we go northwest. We find her."

Martin looked at me, and I knew what he was thinking. Chloe's journal established that she had been walking for five days and hunted for much of that time. After three days without confirmed contact, her chances of being found alive were poor.

But our duty had not changed.

We repacked the rucksack and placed the journal and camera in separate waterproof evidence bags. Gareth slipped the knitted puffin keyring into his pocket rather than putting it back with the kit. It was a small act of care, and none of us commented on it.

Ewan led us away from the clearing. The forest thickened as we entered the Unnamed Glen properly. Ancient Scots pines towered above us, their canopy reducing the force of the rain but deepening the shadows underneath. Lightning pulsed beyond the ridges. Thunder rolled through the ground.

Water streamed between roots and turned the forest floor into slick mud and wet needles. Every step required attention. Ewan stopped at intervals to examine a broken branch, displaced stone or patch of churned earth, confirming that we remained on the creature's trail. Even in the downpour, he moved with certainty through country that looked unreadable to me.

After about twenty minutes he halted.

"Still northwest. No variation."

"Any trace of Chloe?"

"Intermittent. Her route zigzags. She was probably trying to lose whatever followed her."

The implication settled over us. Chloe had spent days fleeing something that walked on two legs and called her name from the darkness.

We paused beneath a rock overhang where the ground was comparatively dry.

"I want the photographs in order," I said. "We need to understand the sequence."

Gareth opened the tablet while Ewan watched the trees.

The progression told a disturbing story. The first day's images were ordinary landscapes, wildlife and camp arrangements. Chloe appeared in several self-portraits, smiling with the mountains behind her.

The second day began in the same way but ended with sunset photographs taken from the ridge, several of them enlarged towards the glen below. Nothing unusual was visible, but the timestamps placed them around the time she first recorded hearing voices.

On the third day, the nature of the pictures changed. There were fewer landscapes and more attempts to record specific details: bark torn from trees, stones placed in patterns too regular to look accidental, and the camp pressed against a rock face exactly as described in her journal. The last image from that day was taken from within her tent. Two reflected points watched from the woodland edge, more than 2 metres above the ground.

The fourth day's photographs were frantic. Some had been taken while she moved. Others documented her doubling back and changing direction repeatedly. Then came the distant bipedal figure, the 46 cm footprint and the gouges high on pine trunks.

There were only three images from Tuesday, 28 July. The first showed her camp at dawn, with the tent already packed. The second showed dense woodland that initially appeared empty. When Gareth enlarged it and raised the contrast, a dark figure became visible behind a tree, much closer than in the previous pictures.

The final photograph, taken at approximately midday, showed Chloe's hand holding her compass. Her fingers had been trembling, blurring the image. The needle and housing indicated northwest, the same direction in which we were travelling.

"She was being stalked," Martin said. "For days."

"And recording it," I said. "Even when she was terrified, she gathered evidence."

Colin looked deeply uncomfortable.

"What sort of animal follows someone for days without attacking?"

"Not an animal," I said, repeating Chloe's words. "At least, not one we know."

I studied the enlarged figure. Even after processing, it remained indistinct. It was roughly human in outline, but too tall and built in the wrong proportions: narrow in places, massively heavy in others, with a head that seemed too small and arms that reached far too low.

"Pack the tablet," I said. "Ewan, carry on."

We travelled for another hour. The rain weakened to drizzle, but low cloud kept the forest unnaturally dim for midday. The ground grew steeper and more difficult. Loose rock shifted beneath our boots. Fallen trees blocked our route, and wet growth caught at our legs.

Ewan stopped abruptly and raised one hand.

We froze. Each of us searched the surrounding woodland while water dripped from the branches.

"What is it?" I whispered.

He did not answer immediately. He crouched over the ground, then slowly looked up into the canopy.

"The tracks change here. It stopped walking. I think it climbed."

I moved beside him. The enormous footprints ended without warning. In their place, deep gouges cut the soft ground, as though a great weight had driven down and launched upwards.

"You think it went into the trees?"

Ewan nodded. "These marks fit something using its limbs to propel itself upwards. A launch point."

Martin, Gareth and Colin gathered close. All of us looked into the canopy. The branches were strong, and the pines grew near enough to one another for something agile to move between them without returning to the ground.

"That's not good," Martin said.

"No," I replied. "It isn't."

The idea of a creature that heavy moving through the trees above us altered the forest. Danger was no longer confined to the ground ahead. It might have been watching us at that moment, following our progress without making a sound.

"Can you find Chloe's trail?" I asked, forcing my attention back to the search.

Ewan moved outwards in a widening spiral, checking mud, roots and protected patches beneath fallen timber. Several minutes later he straightened.

"Got her."

He pointed to the faint impression of a Scarpa boot in mud sheltered by a fallen log.

"She continued northwest."

"And the creature went up," I said. "If it was using the trees to keep alongside her, it could have been above her the entire time."

Colin stared into the branches.

None of us wanted to consider what that meant, but none of us could ignore it.

If the thing could move through the canopy and track Chloe from above, she would have had no chance of spotting it, let alone evading it.

We continued behind Ewan as he followed Chloe's increasingly erratic route through the forest. Her journal and photographs had given us a clear picture of her state of mind: frightened but determined, documenting everything she could while doing all in her power to escape. I could not help admiring her courage, even as my fear for her deepened.

"The prints are getting fresher," Ewan said after we had been walking for about twenty minutes. "There is less rain damage. I would put these at yesterday afternoon."

Hope flared briefly. If we were closing on her last known position, perhaps there was still a chance.

"Look at this," Gareth said suddenly.

He pointed to a tree beside the path. Three parallel lines had been cut into the bark at about chest height. We gathered around them. The marks were deliberate rather than random scratches, each one straight and purposeful.

"She was leaving us a trail," I said. "Clever."

Ewan inspected the cuts.

"Made with a penknife blade, by the look of it. She must have been marking her route in case someone came looking."

I felt a surge of pride for a young woman I had never met. Even in terror, Chloe had kept thinking. She had left breadcrumbs for rescuers to follow.

"Let's increase the pace," I said. "She cannot be far ahead."

We moved more quickly through the pinewood. Ewan found further marks on trees at intervals of roughly 90 metres. The rain had stopped altogether, although water continued to drip from the canopy. After the violence of the storm, the air felt heavy and unnaturally still.

Half an hour later, Ewan froze mid-step. His whole posture changed, the momentum leaving him as alertness took its place. I moved alongside him, careful not to disturb the ground.

"What is it?" I asked quietly.

He pointed to Chloe's boot prints ahead. Their pattern had changed abruptly.

"She started running here. Full sprint. See how only the fronts of the boots are striking?"

The earlier impressions showed a normal walking stride. These were different: only the toes of her Scarpa Terra boots had bitten into the soft earth, each print deeper and much farther from the next.

"Something frightened her," I said.

Ewan nodded, then pointed upwards.

"And look."

It took me a moment to understand what he meant. Nearly 5 metres up the trunk of a massive Scots pine, four parallel gouges had stripped away the bark and bitten several centimetres into the wood. Whatever had made them possessed tremendous strength.

"It dropped down here," Ewan said. "From the canopy."

My mouth went dry. The creature had moved through the trees above Chloe, following her without being seen, then descended directly into her path. That was when she had begun to run.

"How far do the running tracks continue?"

Ewan went on, following the record of her desperate flight across the forest floor. We stayed close behind him, all of us scanning the branches with a new awareness of what might be moving overhead.

After about 180 metres, Ewan stopped at the foot of a low rise where the soft ground gave way to exposed stone. He studied the area, then indicated scuff marks on the rocks.

"She changed direction here. Tried to lose it by crossing ground that would not hold a print."

"Smart," Martin said. "Did it work?"

Ewan slowly shook his head.

"No. Look."

Beyond the rocks, a second line of impressions led away through the trees: the same immense footprints we had been seeing all day. They ran parallel to the direction Chloe had taken.

"It knew where she was going," Ewan said.

Dread settled over me. This was not simply an animal following prey. It was calculating. It had anticipated Chloe's attempt to throw it off and countered her methodically.

"There is something ahead," Colin said.

He pointed through a gap in the trees. About 45 metres away, beyond a break in the pinewood, lay a small clearing. Dark green fabric fluttered from a branch.

We approached cautiously, Ewan leading.

The clearing was roughly 9 metres across and hemmed in by dense Scots pine. In its centre lay a torn dark green sleeping bag, matching the one listed among Chloe's equipment. Sections of tent fabric were scattered across the ground and hung from the surrounding branches.

"This was her final camp," I said as we entered the clearing. "The place where she wrote the last journal entry."

The scene told a violent story. Her tent had not collapsed in bad weather. It had been torn apart. The sleeping bag had been ripped open, its pale synthetic filling strewn across the dark earth like entrails. A small cooking pot lay on its side beside the remains of a compact bottled-gas stove.

Martin crouched beside a dark stain on a flat stone at the edge of the clearing. He examined it without touching it, then looked up at me.

"Blood. Not much, but almost certainly human."

Gareth lifted a strip of shredded tent fabric.

"These are not knife cuts. The fibres have been pulled apart."

Ewan found blood spots beyond the stone, then a broad smear across the wet needles. Drag marks led from the clearing into a nearby stand of pines.

We followed them for less than 30 metres before Ewan stopped and looked up.

Chloe was in the tree.

Her body had been placed roughly 9 metres above the ground, wedged among the heavy branches of a Scots pine. She had not fallen there. Her limbs had been arranged around the trunk with deliberate precision, bent at angles that no living body could have endured.

For several seconds, none of us spoke.

I raised the binoculars. Chloe's face was partly obscured by wet hair, but the extent of her injuries left no doubt. Martin took the binoculars from me and studied her in silence before lowering them.

"She's dead," he said.

My hands would not stop shaking.

What we had found was no longer a rescue. It was a recovery, and whatever had killed Chloe was unlike anything I had encountered in fifteen years of mountain-rescue work.

"We need to bring her down," Martin said quietly.

I nodded, although the thought of climbing 9 metres to retrieve her broken body turned my stomach. We were trained for recoveries, but this was different. Her position was not random. She had been displayed.

"Gareth, try control," I said. "We need additional personnel and proper recovery equipment."

Gareth took out his radio and moved a short distance away, attempting to contact the specialist rescue coordination base near Aviemore. Ewan continued studying the ground around the pine, reading signs invisible to the rest of us.

"What have you got?" I asked.

"Fresh prints. Less than two hours old. Whatever killed her has returned recently."

A chill passed through me.

"You think it is still close?"

"Very likely. And there is more."

He indicated a series of immense footprints circling the tree.

"It has been moving around this area and coming back repeatedly. Almost as if it is checking on her."

Colin returned from scouting the edge of the clearing.

"We have another problem. The weather to the west is coming in much faster than forecast. That Atlantic low has accelerated across the Inner Hebrides."

"Can you get the S-92 in and lift us out?"

He shook his head.

"Not safely. Gusts are already nearing 50 km/h and building. I could not lift off in this. I have secured the aircraft at the landing site, and headquarters knows it is grounded. Earliest possible attempt would be tomorrow morning, assuming this front clears overnight."

Gareth came back, his expression confirming what I expected.

"I cannot hold a clean signal. The weather and terrain are breaking it up. I made partial contact with control. I think they understood that we found her, but little else."

I took a breath and considered our options. Normal procedure was to secure the scene and wait for a recovery team, but we were far from any mapped path. Night was approaching, the aircraft could not fly and something dangerous was still in the area.

"We make camp," I decided. "Somewhere defensible, with clear views in every direction."

"There is a group of boulders about 400 metres back," Ewan said. "Good visibility and some natural protection."

"That will do. Gareth, try control every fifteen minutes. Colin, collect anything we may need overnight. Martin, photograph the scene and take what samples you can without contaminating anything. Ewan, keep watch."

I looked up at Chloe once more. We could not safely bring her down before dark, not with the weather closing and the creature nearby.

"I'm sorry," I whispered. "We'll come back in the morning."

The others moved with practised efficiency, each concentrating on his task. Twenty minutes later we were returning towards the boulders. No one said much. The sight of Chloe's body arranged in that tree had affected every one of us.

The formation was exactly what we needed: five massive rocks forming an uneven ring approximately 9 metres across. The gaps between them were narrow enough that nothing large could pass without being seen, while several flat-topped boulders provided useful observation points.

"This is good," I said. "Four tents in the centre, close together. Gareth and I will share when we rest. Ewan, Martin and Colin each keep their own."

"Andy," Ewan called from the perimeter.

He was crouched at the edge of the trees, examining the ground with his torch.

"You need to see this."

I went to him, already certain I would not like what he had found. His beam illuminated one of the familiar massive footprints pressed deep into soft earth. Its position troubled me more than its size.

"It is facing inwards," I said. "Towards the boulders."

Ewan nodded.

"There are more."

He swept the torch in a slow arc, revealing further impressions.

"They make a complete circuit around the clearing, about 90 metres out."

"How old?"

"Very fresh. Within the past hour, perhaps less."

The meaning was unmistakable. Whatever had killed Chloe knew we were there. It had watched us moving through the area, perhaps even while we stood beneath her body.

"It is watching us," Colin said.

"Get the tents up," I ordered, keeping my voice level. "Tight defensive formation. Then we talk."

The team worked quickly, pitching our four compact tents in a close group at the centre of the boulder ring. Colin finished first and climbed onto one of the flatter rocks, scanning the forest with binoculars. The daylight faded rapidly. As the storm approached, the first rain began to fall.

"Come under cover," I said once the tents were secure. "Colin, get down before the rock becomes dangerous."

We gathered beneath the flysheet of the largest tent, sitting close amid our equipment. Martin opened his medical kit and checked its contents, although I suspected little inside it would help against whatever had torn Chloe apart.

"Here," he said.

He handed each of us a canister of high-output deterrent spray, equipment carried under our specialist operational authority.

"I do not know whether it will work, but it is better than empty hands."

"Marine distress flares as well," Colin said, distributing them. "One each."

We checked our head torches, radios and remaining equipment. The familiar routine offered a measure of comfort. Outside, the rain intensified, drumming against the tent fabric.

"We need to discuss what we are dealing with," I said when there was no longer any point avoiding it.

"It is not any recognised Highland animal," Ewan said. "Not deer, wild boar, a large dog or anything else that should be here. Nothing native leaves tracks like those."

"The position of Chloe's body was deliberate," Martin added. "An animal might cache a kill, but not 9 metres up a tree and arranged in that fashion. Even if we consider an escaped brown bear, the evidence does not fit."

"Her journal said it walked on two legs," Gareth said. "And that it called her name."

Silence filled the tent. I pictured the thing following Chloe for days, calling to her through the trees until she could no longer run.

"Theories?" I asked.

No one answered at first. These were practical, experienced men. They worked with evidence, not folklore or speculation, but everything we had seen defied an ordinary explanation.

"An unknown primate?" Martin suggested at last. "Some undocumented great ape?"

"That would not account for its intelligence," Gareth said. "Or how it knew her name."

"We stay with what we can prove," I said. "The tracks indicate a bipedal animal approximately 2.7 metres tall, based on stride and proportions. It has immense strength, claws capable of gouging deep into timber and the ability to move through trees with ease. It stalked Chloe for several days before killing her. Now it is watching us."

"And learning," Ewan said quietly.

The only sound for several moments was the increasing force of the rain.

"We need a watch rotation," I said. "Two-hour shifts, two people at a time. No one goes anywhere alone, not even for a piss. Maintain radio contact throughout."

Everyone nodded.

"Ewan and I will take 23:00 to 01:00. Martin and Gareth take 01:00 to 03:00. Colin and I take the pre-dawn watch from 03:00. If there is activity during a handover, the outgoing pair stays in position until the situation is settled. Any questions?"

There were none. We had worked together long enough for everyone to understand the gravity of our position. Something dangerous was stalking us. Our priority was to survive until morning.

"Try to rest," I told them. "Once the weather clears, we contact control, arrange road or air support and recover Chloe."

Martin and Colin withdrew to their tents. Gareth put his gear in the tent he and I would share. Ewan and I took positions on opposite sides of the camp, using the boulders for shelter while maintaining views of the surrounding pinewood.

The storm strengthened. Wind lashed the trees and rain came down in sheets. Lightning flashed in the distance, followed by thunder that seemed to shake the ground. Between flashes, the darkness was almost complete. Our head torches produced small pools of light that barely penetrated the downpour.

"Movement, three o'clock," Ewan said over the radio, his voice nearly lost beneath a crack of thunder.

I turned towards the bearing he had given and searched the tree line. At first I saw only rain-beaten pines twisting in the wind. Then lightning illuminated the forest and, for a fraction of a second, I saw something large moving between the trunks.

It was far too big to be any ordinary animal.

"I saw it," I radioed. "No useful detail."

"It is circling again," Ewan replied. "Testing the perimeter."

I raised the binoculars and waited for another flash. The forest remained dark for what felt like several minutes. When lightning split the sky again, I caught a clearer view.

A massive, dark figure was moving with startling grace just inside the tree line, about 70 metres away. The light vanished too quickly for me to distinguish its features, but the shape was unmistakably bipedal and far larger than a person.

"We are not equipped for this," I said quietly over the radio.

"No," Ewan replied. "We are not."

The two hours passed with agonising slowness. The creature maintained its distance, appearing occasionally in lightning flashes as it circled us. It never entered the boulder ring. It seemed content to observe from among the trees.

At 01:00 I woke Martin and Gareth and told them what we had seen.

"It is keeping about 70 metres out and circling the camp," I said. "We have visual confirmation, but no clear view of the face or hands. If it closes in, wake us at once."

Martin nodded.

"We will watch it. Get some sleep, Andy."

I crawled into the tent I shared with Gareth, lay fully dressed on my sleeping bag and kept my boots on. Sleep seemed impossible. Rain hammered the fabric and the wind threatened to rip away the flysheet, but exhaustion eventually dragged me under.

My dreams were full of enormous footprints and Chloe's broken body in the pine, her limbs bent into impossible angles.

The radio crackled and pulled me awake.

"Andy."

Gareth's voice was taut.

"The storm is easing, but our visitor is getting bolder. It has come within about 45 metres. We delayed the 03:00 handover because it was moving."

I checked my watch. It was 03:15. I had slept for just over two hours.

"Coming out. Wake Colin as well."

I stepped into a light drizzle. The main front had passed, and breaks in the cloud allowed occasional moonlight through. Better visibility should have reassured me. Instead, the half-light filled the forest with shifting shadows.

Martin crouched atop one of the boulders, his head torch off to preserve his night vision. Gareth stood below him with the radio in his hand.

"Where?" I asked.

Gareth indicated the northern edge of the perimeter.

"There, five minutes ago. Moving slowly between the trees."

Colin emerged from his tent, alert despite being woken.

"What is happening?"

"Our friend is curious," I said. "It has moved closer."

The four of us spread around the camp, each covering a direction. Ewan emerged moments later, apparently roused by the movement and tension.

For several minutes we saw nothing. After the storm, the forest was unnaturally quiet. There were no animal calls and no insects, only water dripping from the branches and the sound of our breathing.

Then I heard it.

A low noise unlike anything I had encountered before. It was not quite a growl and not quite a human voice, but a rumbling vibration that seemed to come from everywhere at once.

"Do you hear that?" Colin whispered over the radio.

Four replies came together.

"Yes."

The sound faded, then returned from somewhere closer. There was a pattern in it now, almost like speech, although the tones could not have come from a human throat.

The hair rose on the back of my neck. The thing was attempting to communicate.

"It is talking," Gareth whispered.

"Or trying to lure us out," Martin said.

The vocalisation continued, moving around the perimeter as the creature called from different positions. It disturbed me at a level beyond reason, mixing recognisably human cadences with sounds no person could produce.

"Everyone stays where they are," I ordered. "No one leaves the perimeter, whatever you hear."

The creature fell silent. The absence of sound was worse, leaving us straining for any indication of movement.

"Visual," Ewan said calmly over the radio. "South-east side, just inside the trees. It is watching us."

I turned slowly. In the faint moonlight, I made out a shape standing motionless between two pines. It was at least 2.5 metres tall, perhaps closer to 2.7, and unnaturally still. Even at that distance, the intensity of its attention felt almost physical.

"Can everyone see it?" I asked.

Four quiet confirmations came back.

"What do we do, Andy?" Martin asked. "Try to drive it off?"

Aggression might provoke an attack. Remaining passive might encourage it.

"Lights on my signal," I said. "All five head torches at full output. Aim directly at it and watch the reaction."

I counted down from three. On my signal, every light came on, the combined beams cutting through the darkness and striking the gap between the trees.

Nothing was there.

The creature had moved during the seconds between our last sight of it and the lights coming on.

"Where did it..." Gareth began.

"Two o'clock!" Colin shouted. "It has moved."

We swung the beams right and caught something racing along the tree line with extraordinary speed: dark fur, long limbs and a body far too large to move so quickly. It vanished into the deeper shadows.

"Did you see how fast it was?" Gareth asked, his voice unsteady.

"Keep the lights on," I ordered. "Hold the perimeter."

For the next hour we remained at our positions, occasionally glimpsing the creature as it circled. It appeared to be testing our defences, observing our reactions and learning our routines.

Its intelligence was the most disturbing part. This was not mindless animal behaviour. It was calculated surveillance.

As the first pre-dawn light appeared in the east, its visits became less frequent. By full dawn, more than thirty minutes had passed without a sighting.

"I think it has gone," Colin said cautiously as we gathered in the centre of camp.

"For now," Ewan replied.

He had begun examining the ground beyond the boulders.

"It left plenty of evidence. Fresh tracks from different points throughout the night. It watched us from every side."

We broke camp quickly, packing the four tents and our equipment with practised efficiency. None of us wanted to remain there a moment longer than necessary.

"Gareth, try control again," I said. "The main front has passed. Reception may be better."

After several attempts, his expression brightened.

"I have the coordination base. Weak signal, but stable."

He handed me the radio. I identified myself to the controller who answered.

"Control, this is Andrew Mercer, specialist mountain-rescue team leader. We have located Chloe Bennett. She is deceased. We require extraction and a recovery team. Colin Fraser's S-92 remains secured and grounded at the landing site."

The reply was broken by static, but I understood the essentials. HM Coastguard would reassess flying conditions and attempt extraction when safe, with an estimated arrival around 12:00 if the secondary weather front held off.

"Understood," I replied. "We will prepare a landing area near our grid reference and mark it with smoke on approach."

I returned the radio to Gareth, allowing myself a small measure of relief. In a few hours, we might be out of the Unnamed Glen and able to return Chloe to her family.

"What do we do until then?" Martin asked.

"Return to Chloe, bring her down and prepare her for transport. Then establish a landing area in the clearing we passed about 800 metres back."

No one wanted to see that tree again, but we understood our duty. We shouldered our rucksacks and set out with Ewan leading.

Throughout the walk, I could not escape the sensation of being observed. Every shadow seemed to conceal something waiting among the pines. The creature had withdrawn with daylight, but I was sure it had not gone far.

It was waiting for another opportunity.

Chloe's body looked no less appalling in the morning light. Martin and Colin prepared the climbing and recovery equipment while Ewan and Gareth watched the perimeter. I stood beneath the pine and stared up at her.

In daylight, I could see more clearly the terrible precision with which she had been arranged. It spoke of intelligence and purpose, not random violence.

"Why?" I whispered.

Why display her?

The forest offered no answer. The wind shifted, carrying the smell of wet pine and peat, and I became certain that whatever had killed Chloe Bennett was still nearby.

As my team prepared to climb and bring her down, I could not shake the conviction that it did not regard us as a threat. It saw us as prey.

Colin climbed while Martin managed the rope system from below. They freed Chloe from the branches and lowered her carefully. When she reached the ground, we placed her in a recovery bag with as much dignity as we could. No one spoke as Martin closed it.

Some horrors were beyond words. What had been done to Chloe was one of them.

Our extraction plan collapsed almost as soon as it had formed.

Gareth's radio crackled with an update from control. A secondary front was driving into the Highlands, bringing winds strong enough to prevent Colin from lifting off and to ground any replacement aircraft. The forecast had failed us again. Road-based responders were being considered, but they could not reach our present location.

"We are here for another night," I told the others after the transmission ended. "Extraction is delayed until 08:00 on 30 July 2026, subject to conditions."

Four pairs of eyes met mine. Every one of us was thinking the same thing.

Another night with that creature hunting us.

"We need better shelter," Martin said, looking towards the darkening sky. "Somewhere more defensible than the boulders."

Ewan nodded.

"There is a narrow corrie about 3 kilometres northwest. A natural bottleneck, with rock walls on three sides. Easier to hold than open ground."

Carrying Chloe's body over rough terrain in fading light would slow us dangerously, but leaving her felt wrong on every level.

"We secure her here," I decided at last. "Record the OS grid reference and return with the recovery team."

No one argued. We moved the sealed recovery bag between two fallen trees, covered it with a secured tarpaulin and weighted the edges with rocks. Gareth recorded the grid reference and transmitted it during the next brief window of radio reception.

We set out for Ewan's proposed site as dusk settled over the forest.

The corrie was well chosen. A narrow entrance opened into a flat area surrounded on three sides by steep rock walls. We could watch the only practical approach while keeping solid stone at our backs.

"Four tents grouped in the centre," I ordered. "Colin's goes farthest from the entrance. Ewan and Martin, yours nearest the opening. Gareth and I will share in the middle."

Everyone understood the logic. Colin had already flown us into the area before worsening winds forced him to secure the S-92 and join the ground party. He needed uninterrupted rest if there was any chance of flying the next morning. Ewan and Martin were the strongest in a direct confrontation.

No one voiced the real reason for the formation. We expected another visit.

We established camp with disciplined speed and ate cold expedition meals and oat bars rather than lighting a stove. Once darkness had fallen, we gathered for a final briefing.

"Two-person watches, as before," I said. "The tents remain together. Nobody leaves the perimeter alone. Maintain visual contact with at least one other member of the team at all times."

They nodded.

"We also need a silent signal. Three rapid radio clicks means trouble. If you hear it, everyone converges immediately."

We reviewed the procedure, then began the first watch. Ewan and I took the opening shift, followed by Martin and Gareth. Colin would sleep through so that he had the best possible chance of flying if the weather allowed.

The first few hours passed without incident. Ewan and I held separate positions with clear sight lines to one another, watching the corrie entrance and the forest beyond. The sky had cleared and stars shone over the mountains. Under any other circumstances, the view would have been beautiful.

"Anything?" I asked quietly over the radio.

"No movement," Ewan replied. "But it is too quiet."

He was right. The ordinary sounds of a Highland night were absent. No owls called. No small animals moved through the undergrowth. Even the insects seemed silent. It felt as though the forest were holding its breath.

When our shift ended, I woke Martin and Gareth while Ewan briefed them on the silence. I crawled into the tent Gareth and I shared. Exhaustion pressed down on me despite my determination to remain alert. The previous night's broken sleep, combined with the physical and emotional strain of the day, was catching up with me.

I must have fallen deeply asleep.

A sound wrenched me awake, although for an instant I could not identify it. Fabric ripped apart, followed by a human scream that stopped with terrible suddenness.

"Colin!"

Martin shouted outside.

I seized my torch and burst from the tent. A massive shadow moved with impossible speed at the edge of the camp. It was far larger than a human and dragging something towards the trees.

"God, no," Gareth gasped beside me.

Ewan appeared with a torch in one hand and deterrent spray in the other.

"Stay together!" he shouted, sweeping the powerful beam across the retreating shape.

The light caught only fragments: a broad back covered in dark, matted fur, a limb much too long for its body, and Colin's limp form held in what looked like claws. His face flashed pale in the beam before the creature vanished.

"Colin!" Martin called into his radio. "Colin, respond."

Only static answered.

"Jesus," Gareth whispered. His torch settled on the wreckage. "Look at his tent."

Colin's tent had been destroyed. It had not collapsed or blown down. Something had torn it open from top to bottom. The synthetic fabric hung in strips as if slashed by immense knives. His sleeping bag had been dragged halfway out and lay empty.

Ewan was already examining the ground around it.

"It approached from behind," he said, his voice tight with controlled fear. "It came in low, almost crawling. These prints were not here during our watch."

"How did it get that close without anyone hearing?" Gareth asked.

No one answered. The truth was too frightening. Despite its size, the creature could move with extraordinary stealth. It had worked its way behind our camp, reached Colin's tent without alerting four experienced rescuers and taken him in seconds.

I joined Ewan at the edge of the camp. The ground showed how Colin had been dragged away. Huge impressions marked where the creature had driven its claws into the earth for leverage. Five indentations were spread across the soil, each ending in a deep gouge.

"Martin," I said, forcing my voice to remain steady. "What are our options?"

He shook his head, his face grey in the torchlight.

"We cannot follow that thing in darkness. Even if we could..."

He did not need to finish. We had all seen what had happened to Chloe.

Colin was dead, or soon would be.

"We move," I said, forcing my mind through the shock. "It took Colin because his tent was farthest from the entrance and most exposed to a rear approach. It chose him."

Ewan nodded.

"It was not random. It studied the camp and selected the most vulnerable target."

The implication settled over us. This was more than a predator. It was an intelligent hunter capable of assessing our arrangements and acting strategically.

"The Coire Dubh Warden's Bothy," Gareth said, checking his GPS against the OS mapping. "Approximately 24 kilometres northwest from here. We may reach it after first light if we keep moving."

"Pack essentials only," I ordered. "Head torches, radios, GPS units, water, emergency food and first-aid kit. Leave the rest."

We moved with desperate efficiency. Colin had been taken less than five minutes earlier. The creature might return at any moment.

"Radio check. Channel two. Keep transmissions brief."

Three radios clicked in acknowledgement.

"Weapons?" Martin asked, gripping his knife.

"Deterrent spray and flares," I said. "Use them only in a direct attack."

We stood in a tight circle and checked our rucksacks one final time. One of us had been taken by something we could not explain, and roughly 24 kilometres of broken forest and mountain terrain lay between us and the nearest refuge.

"Single file," I said, checking the grid reference Gareth had transferred to my GPS. "I lead. Ewan covers the rear. Martin and Gareth stay between us. Red filters on the head torches."

We abandoned the camp as it stood. The tents remained pitched, Colin's belongings scattered around the shredded remains of his shelter. There was no time to clear the site, and none of us wished to stay.

As we left the corrie and entered the forest, I could not rid myself of the image of that massive shape carrying Colin away.

In all my years of mountain rescue, I had never felt so helpless. We were trained to go towards danger and bring people home. Now our only chance was to run.

The pinewood seemed to close around us. Branches reached across the path like grasping hands. Under the red-filtered light, everything carried a bloody tint. We moved as quickly and quietly as the terrain allowed, each step taking us farther from the camp but not necessarily closer to safety.

Somewhere behind us in the darkness of the Unnamed Glen, Colin was being carried towards the same fate that had claimed Chloe Bennett.

I was certain the creature would come for the rest of us.

We pressed on as shadows crowded the forest. Even with the GPS guiding us towards Coire Dubh Warden's Bothy, the trees formed a maze that seemed designed to hold us. Our red lights turned familiar trunks into threatening silhouettes.

Ewan guarded the rear, stopping periodically to search for signs of pursuit. Martin moved quietly through the trees, his medical kit reduced to essential supplies. Gareth remained close to me, clutching his radio against his chest and making brief attempts to contact Police Scotland control at Inverness or the rescue base.

"Still nothing," he whispered after another failed call. "The mountains are blocking us."

I nodded and kept moving. We needed to conserve our strength, and unnecessary speech would only help the creature locate us.

The 24 kilometres to the bothy felt impossible, yet it was our only hope. After an hour, we had covered perhaps 5 kilometres of difficult ground, leaving about 19 kilometres. The faint deer path we followed twisted through dense undergrowth, disappearing beneath peat and fallen branches before emerging again farther on.

I checked the GPS and confirmed that our bearing remained northwest.

Then I heard something behind us.

Branches broke with reports like gunshots. These were not twigs snapping beneath deer or the heavier movement of wild boar. Thick limbs were being torn aside by something travelling with tremendous force.

Ewan appeared beside me so suddenly that I nearly recoiled.

"It is following," he said, barely above a whisper. "Less than a kilometre back and closing quickly."

Martin joined us, his face grim in the red light.

"Options?"

I searched for an answer, knowing how few we had. We might try to outrun it, but Ewan spoke before I could finish the thought.

"We cannot outrun it. Not while we remain together. It is too fast."

Gareth tightened his grip on the radio.

"Then what do we do?"

Silence fell between us as we listened to the pursuit drawing closer. Something large was coming through the forest, and it was no longer bothering to conceal its approach.

"I'll draw it off," Ewan said at last.

"No," I replied immediately. "We stay together."

Ewan shook his head. "This thing is hunting us, Andy. It isn't going to stop. But I can lead it away and buy you time to reach the bothy."

"That's suicide," Martin said harshly.

"Maybe," Ewan agreed. "But three of you have a better chance than four of us trying to outrun it together."

I wanted to argue. I wanted to order him to stay with us, but the cold logic of the situation was undeniable. The sounds of pursuit were growing louder, branches breaking as the creature closed the distance.

"I'm the best tracker," Ewan continued, already removing his rucksack. "I know how to move through this forest better than any of you. I can keep it occupied long enough for you to get clear."

I caught his shoulder. "Ewan..."

"Andy," he interrupted, using my first name for perhaps the first time in all our years of working together. "You know I'm right."

He was. God help me, he was right, and all of us knew it.

Ewan handed me his emergency supplies: water filter, first-aid kit and spare batteries. He kept only his knife, head torch and the high-output deterrent spray we carried under specialist operational authority.

"Get to Coire Dubh Warden's Bothy," he said. "Get help. Come back for Colin and me with authorised firearms officers."

I nodded, unable to speak past the constriction in my throat. Martin clasped Ewan's hand briefly. Gareth simply stared at him, his face rigid with shock and fear.

"About 19 kilometres remaining, northwest," Ewan reminded me, tapping the GPS unit clipped to my jacket. "Keep to the grid bearing until you reach the forestry access track. Don't stop for anything."

Before I could say anything more than, "Thank you. Goodbye. I'm sorry," Ewan slipped into the undergrowth, heading south and away from our planned route.

Within seconds, the darkness swallowed him completely.

"Keep moving," I ordered Martin and Gareth, my voice rough. "Stay on the bearing."

We continued northwest, moving as quietly as possible.

Behind us, Ewan's voice suddenly rang through the trees, deliberately loud.

"Here! Over here!"

The sounds of pursuit changed direction at once. Branches snapped as the creature turned towards his calls.

Ewan was making as much noise as he could, drawing its attention away from us. I pushed Martin and Gareth onwards, increasing our pace now that stealth mattered less. Ewan was buying us time with his life, and we could not waste a second of it.

For ten minutes we moved in silence, the forest around us quiet except for our breathing and the strike of our boots against roots and peat.

Then Ewan's voice echoed through the trees again, much farther away.

"Stay back! Get away from me!"

His shouts were followed by a sound that froze my blood: a roar unlike anything I had ever heard, neither wholly animal nor remotely human.

The forest seemed to hold its breath. Then came the sounds of a struggle - undergrowth crashing, one human cry cut abruptly short, more branches breaking and, finally, silence.

Complete, terrible silence.

Gareth stopped and looked back. "Should we...?"

"Keep moving," I said, the words like ash in my mouth. "He's gone."

Martin met my eyes. His expression reflected the sick certainty in my own mind. Ewan was dead, like Colin, like Chloe.

And we would join them unless we reached the bothy.

We continued northwest, each step carrying us closer to possible safety but weighted by the knowledge of what Ewan had sacrificed.

The GPS showed 16 kilometres remaining. The sounds of pursuit had stopped completely. The forest around us was unnaturally quiet. There were no birds and no insects, only the soft tread of our boots and our controlled breathing.

"It stopped following us," Gareth whispered hopefully after another few kilometres.

"No," Martin replied, scanning the darkness. "It's hunting more carefully now."

I knew he was right. The creature had learnt from each encounter. It had studied our routines before taking Colin from the second camp. It had pursued us openly until Ewan broke away. Now it would adapt again.

The GPS showed 13 kilometres remaining when Gareth's radio crackled with static, making all three of us jump. He fumbled with the volume control and quickly turned it down.

"Sorry," he whispered. "I've been trying different channels. I thought we might reach control or one of the wardens."

The static continued, broken by bursts that sounded like a voice forcing its way through the interference. Gareth adjusted the frequency, his face intent.

Then we heard it.

"Help."

A pause.

"Location. Injured. Need assistance."

Gareth's eyes widened. "That's Ewan."

The voice returned, clearer this time.

"This is Ewan MacLeod. Injured but alive. My grid reference is..."

Martin moved so quickly that I barely saw him reach for the radio. He tore it from Gareth's hand and switched it off.

"That isn't Ewan," he hissed, his face pale.

"What? But I heard him -"

"Listen to me," Martin cut in. "It was close, but it wasn't his voice. The cadence was wrong. The tone was wrong."

A chill travelled down my spine as I understood what he meant. The transmission had sounded like Ewan, but something about it had been subtly distorted, as if the speaker were reproducing human speech without understanding it.

"It's learning," I whispered. The implication struck me with sickening clarity. "It's imitating him to draw us back."

Gareth looked ill. "It knows how the radios work. It's trying to trick us."

"Keep moving," I ordered, fighting to steady my voice. "Don't transmit again unless you're certain you've reached control."

We pressed on. The knowledge that the creature was not merely hunting us but actively trying to deceive us added another depth to the terror. It was not only immensely strong and fast. It was intelligent enough to turn our own equipment against us.

The pinewood seemed to close around us, every shadow a possible hiding place. I thought of Ewan, who had given his life so we might escape. Of Colin, taken from beside the grounded S-92. Of Chloe Bennett, stalked for days before being killed and deliberately arranged in that Scots pine.

The radio remained silent in Gareth's pocket, but the damage had been done. We knew now that the creature could learn, adapt and imitate. Somewhere in the darkness around us, it was watching and waiting for an opportunity to take another one of us.

I tightened my grip on the GPS and concentrated on the blinking marker for Coire Dubh Warden's Bothy. Thirteen kilometres of forest, bog and rough ground remained between us and shelter, with something hunting us that could speak in our dead friend's voice.

We had no choice but to keep moving.

Just before dawn, after hours of forcing our way through dense pinewood and over sodden peat, we stumbled out beside the forestry access track. Coire Dubh Warden's Bothy stood ahead of us, its dark outline hard against the fading night.

The distance on the GPS fell to zero.

The small timber building looked like salvation itself.

"Thank God," Gareth wheezed, his breath coming in ragged gasps.

We approached cautiously, our bodies aching after the punishing pace we had maintained through the night. The bothy was a plain, single-storey building with reinforced windows, external storm shutters and a heavy wooden door. It was not much, but after what we had endured it looked like a fortress.

I tried the handle. The door opened easily.

"Standard emergency arrangement," I explained as we filed inside. "The wardens leave it accessible for casualties caught out in severe weather."

"People like us," Martin said grimly, securing the door behind us.

The interior was basic but functional. The main room contained a desk, radio equipment and OS maps pinned to the walls. A small kitchenette occupied one corner, while a storage cupboard ran across most of the back wall. The air smelt musty but clean, with traces of pine disinfectant and old tea.

Gareth went straight to the desk telephone and lifted the receiver. His face fell almost immediately.

"Dead," he reported, replacing it with a defeated thud. "The storm must have brought the line down."

Martin was already checking the perimeter and drawing the heavy shutters closed.

"We need to secure the place," he muttered, moving with mechanical efficiency despite his exhaustion.

One front shutter had been twisted by storm damage and would not sit flush against its frame. Martin forced it as close as he could and wedged the internal catch, but a narrow exposed section of reinforced glass remained beside it.

I searched the storage cupboard for anything useful. Behind the creaking door stood metal shelves packed with emergency supplies: bottled water, first-aid kits, blankets, torches and, inside a locked steel cabinet marked for authorised emergency use, two estate deer-management rifles chambered in .308 Winchester.

The key hung inside a sealed box beside the cabinet. I broke the seal, unlocked it and removed the weapons.

"Martin," I called. "We've got rifles."

He paused to inspect them. Both were well maintained, bolt-action weapons with five-round internal magazines. The cabinet also held forty boxed cartridges.

I loaded five rounds into each rifle and divided the remaining thirty equally between us, fifteen spare rounds apiece.

"Five ready, fifteen spare," Martin said, slipping his ammunition into a jacket pocket. "Twenty each. Better than nothing."

Gareth had moved from the dead telephone to a battery-powered radio set on a side table. His fingers worked across the controls with practised precision.

"I'm trying every emergency frequency," he said, adjusting the aerial. "If anyone is listening, they should hear us."

I continued the inventory while Gareth worked the radio and Martin reinforced our defences. The bothy was better supplied than I had expected. We found marine distress flares, more first-aid equipment than we could carry, enough emergency food for a fortnight, water-purification tablets, spare clothing and detailed OS maps of the surrounding estate.

Under normal circumstances, we would have had everything required to wait safely for rescue.

These were not normal circumstances.

For thirty minutes we allowed ourselves to hope. We took turns watching the pinewood through the narrow gaps in the shutters while Gareth sent repeated distress calls. Martin made tea on a bottled-gas camping stove, and we forced ourselves to eat oat bars and bland emergency rations, our first proper food since before Colin had been taken.

"Someone will hear us," Gareth insisted, though his eyes were less confident than his voice. "Police Scotland control at Inverness will have staff monitoring by now."

I nodded, unwilling to extinguish what little hope he had, but we could not rely on a quick rescue. Even if Gareth reached control, road-based responders would need hours to reach this remote track. The secondary Atlantic front had ruled out another flight, just as the worsening wind the previous evening had prevented Colin from lifting the S-92 and forced him to secure it at the landing site.

Martin finished his tea and moved to the front window, peering through the narrow opening left by the damaged shutter. I was going through a first-aid kit and selecting supplies in case we had to leave quickly when his voice cut through the stillness.

"Movement in the trees," he said. His tone was flat, but his body tightened. "Ten o'clock, at the edge of the clearing."

I took my rifle and joined him, squinting into the grey pre-dawn light. For several seconds I saw nothing. Then a dark shape shifted among the Scots pines, something massive moving with the same unnatural grace we had witnessed before.

"It found us," I whispered, my mouth dry.

Gareth abandoned the radio and crossed to another window. "I can't see anything."

"It's circling," Martin said, tracking something that had already vanished from my angle. "Keeping just inside the tree line and moving anticlockwise around the building."

I hurried to the rear window and eased back the edge of its shutter. Through the reinforced glass I could see the forest roughly 45 metres away, the dark pines standing like sentries against the brightening sky.

At first there was nothing unusual. Then one pine swayed against the wind, its upper branches shaking as something large moved past the trunk.

The smell reached us next, so foul that it seemed to seep through the sealed windows: rotting meat, wet fur and something else I could not identify. Something old and profoundly wrong.

I fought the urge to gag. "Can you smell that?"

Martin nodded, his face paling beneath the stubble. "It's what I smelt just before it took Colin."

Gareth's radio burst into static, making us all flinch. He rushed back and adjusted the controls.

"I think I'm receiving something," he said, desperate hope tightening his voice.

A new sound drew my attention to the window: slow, deliberate scratching against the outside wall. I watched deep gouges appear in one of the exposed timber boards, carved through the wood as easily as wet clay.

The creature was testing our defences.

"It's starting," I warned, stepping away from the window and checking the rifle.

Martin took position near the door, his weapon ready. "Gareth, keep trying the radio."

The scratching moved around the building as the creature circled us. Then it stopped. The silence lasted several heartbeats.

The first impact against the door sounded like a vehicle striking it. The heavy wood shuddered in its frame.

Gareth flinched so violently that he dropped the radio microphone.

"Jesus," he breathed.

The second impact was stronger. Part of the frame split with a sharp crack. The door was built to withstand desperate people and large animals, but whatever stood outside was stronger than any living bear could have been.

"Gareth," I said, holding my voice steady with an effort. "Concentrate on the radio. It is our only chance."

He nodded and resumed transmitting while the creature continued its assault. Each blow shook the entire bothy and sent dust drifting from the roof timbers.

"This place wasn't built to keep out something like that," Martin said, backing away from the damaged door.

He was right. The bothy had seemed reassuring when we arrived, but now it felt like a trap: a timber box with few exits and nowhere to run.

The assault stopped without warning.

The silence that followed was worse than the pounding.

"What's it doing?" Gareth whispered, his knuckles white around the microphone.

We learnt the answer seconds later, when something heavy landed on the roof. Dust showered down and the timbers creaked as a tremendous weight shifted above us.

"It's learning," I said, cold spreading through me. "It's testing every possible entrance."

The creature moved across the roof towards the chimney, each footfall making the ceiling beams groan. Then it became silent again.

Gareth turned back to the radio, frantically adjusting the controls. His expression changed.

"I've got someone," he exclaimed. "I think it's -"

The room exploded into chaos.

The creature tore the damaged external shutter free and smashed both massive arms through the front window. Reinforced glass, splintered timber and the bent metal catch flew across the room.

Martin was standing nearest. He did not have time to shoulder his rifle before long, clawed fingers closed around his upper body.

I fired at the arm. The rifle's report was deafening in the confined space. Dark fluid sprayed from the wound, but the creature did not release him.

If anything, its grip tightened as it dragged Martin towards the shattered window.

"No!" I shouted.

I worked the bolt and fired again, then a third time. Martin's scream stopped abruptly as he was wrenched through the opening, his body bending at an impossible angle to pass through it. His rifle struck the floor where he had been standing.

Gareth snatched it up and fired through the window. Panic ruined his aim. He worked the bolt and fired again.

"Martin!" he screamed. "Martin!"

Terrible sounds came from outside: wet, tearing noises I forced myself not to interpret.

Then the side shutter was ripped bodily from the wall. The reinforced window behind it shattered.

Gareth spun towards the opening, still holding Martin's rifle. The creature was too fast. One arm thrust through the broken window and seized him around the chest before he could fire again.

His ribs broke with sickening clarity as the massive hand contracted. Gareth's scream rose high and thin, then ended as he was pulled through the window. His legs kicked frantically before disappearing into the grey dawn.

I stood alone in the centre of the bothy, my rifle half raised. Broken glass covered the floor, and the creature's stench filled the room. Outside, Gareth's screams became wet, gurgling sounds and then ceased.

The building that had seemed solid and secure half an hour earlier now felt like a paper box waiting to be torn apart. Two windows were destroyed, and repeated impacts had split the door frame.

I was the last surviving member of the five-person rescue team that had entered the Unnamed Glen less than twenty-four hours before. Colin, Ewan, Martin and Gareth were all gone. Chloe had been dead before we arrived.

Whatever had killed them was still outside, still hunting.

The only sounds were my ragged breathing and the soft static from the radio Gareth had dropped. I forced my legs to move, crossed to it and picked up the microphone.

"Emergency," I said, my voice strange in my own ears. "This is Andrew Mercer, specialist mountain-rescue team leader, calling from Coire Dubh Warden's Bothy. My team is down. Repeat, my entire team is down. There is something in these woods. Something is hunting us."

The radio crackled. Through the static, a faint voice replied.

"Coire Dubh Bothy, this is Police Scotland control at Inverness. We received your distress call. Confirm your grid reference and situation."

I read the grid reference from the OS map beside the set.

"Four men dead," I continued. "I need immediate armed extraction. The creature that took them is still here, outside the building."

"Say again. Did you say 'creature'?"

The controller sounded confused, doubtful.

Before I could answer, a low growl came from immediately beyond the shattered front window. It was so deep that I felt it in my chest rather than heard it.

The smell intensified. The creature was standing outside, listening as I reported its existence.

The microphone shook in my hand as I pressed the transmit switch again.

"Send armed help. Please hurry."

I set the microphone down and raised my rifle towards the shattered window through which Martin had been taken. Something moved just beyond my field of vision, waiting for the chance to finish what it had begun.

I stood in the wreckage of Coire Dubh Warden's Bothy, surrounded by broken glass and the bitter smell of propellant. The radio hissed with static while Police Scotland control repeatedly asked for clarification, details and confirmation of my impossible account.

My hands would not stop shaking.

Martin and Gareth had been taken in seconds by something that had ripped through a storm shutter and reinforced glass as if they were paper. I wanted to scream, to fire blindly into the forest, to do anything except stand there and listen to it circle the building.

Its movements were deliberate. Heavy steps crushed pine needles outside. Claws occasionally scraped along the timber walls, searching for weaknesses. Every few minutes a low growl vibrated through the remaining intact windows, deep enough to make my teeth ache.

I held the rifle tighter, though I knew how little protection it offered. I had hit the creature three times when it took Martin, and it had barely reacted. The fluid sprayed from the wounds had looked nothing like ordinary blood. It was too thick and dark, almost black in the poor light.

The radio crackled again.

"Coire Dubh Bothy, respond. Road teams are being dispatched. Estimated arrival four hours. Confirm your situation."

Four hours. I would be dead long before then if I stayed.

The sounds outside stopped suddenly.

The silence stretched through one minute, then two. I forced myself towards the shattered front window, stepping over broken glass. With the rifle braced against my shoulder, I looked into the clearing.

Nothing moved.

The creature had vanished, but so had Martin and Gareth's bodies. There was no blood and no obvious sign of struggle, only empty ground where my friends should have been.

I knew I could not remain there. With two windows open and the door frame split, the bothy was a death trap. One more heavy impact would bring the door down.

Help was coming too slowly. The Glenmore access gate was approximately 13 kilometres away by the forestry road, or 10 kilometres if I took the direct maintenance path through the woods. Even the shorter route seemed impossible in my condition, but staying meant certain death.

I gathered what I could carry: my rifle, with two rounds still loaded and fifteen spare; Martin's rifle, with three rounds remaining and thirteen spare, which I slung across my back; a water bottle; a compact first-aid kit; two marine distress flares; and a portable national park radio from a desk drawer.

My hands worked mechanically while my mind raced through estimates. On the maintenance path, injured and exhausted, I might cover 5 kilometres an hour if the ground remained passable. I could reach Glenmore in two hours, perhaps a little more.

If the creature found me...

I could not think about that.

The rear window was intact, but its frame had loosened under the impacts that shook the building. I used the rifle butt to break the glass and cleared enough of the jagged edges to climb through.

The dawn air was cold against my face as I lowered myself outside and landed softly. I crouched beneath the window, scanning the tree line.

The forest was silent. No birds called. No small animals stirred in the undergrowth. There was only the whisper of wind through pine needles.

Keeping low, I moved quickly towards the trees on the opposite side of the clearing from where I had last seen the creature. The instant I reached the forest edge, I felt exposed, certain that eyes were watching me from the darkness between the trunks.

I had to keep moving. Standing still meant death.

A narrow deer path wound between the trees, barely visible in the grey morning light. I followed it as quietly as my exhausted legs allowed. Every step felt like a betrayal of my team. Colin, Ewan, Martin and Gareth were all gone, and I was running away.

Not away, I told myself. Towards help. Towards the chance to ensure that what had happened to them would not happen to anyone else.

The first hour passed in tense silence. I maintained the best pace I could, faster than ordinary walking but short of a run, conserving what remained of my strength.

As dawn grew into early morning, the forest gradually brightened. Birds began to call hesitantly from the canopy. I took it as a hopeful sign. Wildlife fell silent when a predator was near.

Perhaps the creature had lost interest. Perhaps four members of my team had been enough. Perhaps it could not track me through the dense undergrowth.

The deer path broadened and joined another, then another, until I emerged on an old maintenance path that would eventually meet the forestry road.

I checked my watch. I had been moving for almost an hour and a half. My legs ached, and my lungs burnt with exertion and the cold mountain air, but I forced myself onwards.

Then I heard it.

Behind me, far away but unmistakable, came the sound of branches breaking. It was not the gentle crack of wind-tossed limbs, but the sharp report of something large moving through the forest at speed.

It had found me.

I abandoned any attempt at stealth and began to run, my boots pounding the muddy path. The forestry road could not be far. Once I reached its firmer surface, I could make better time.

More branches snapped behind me, closer now.

The creature was gaining.

The path curved around a vast Scots pine, and the forestry road appeared ahead: a broad gravel track running between the trees, wide enough for emergency vehicles.

I turned towards Glenmore and ran as hard as I could. Gravel ground beneath my boots, every impact driving pain through my exhausted legs. My lungs felt filled with fire rather than air. The two rifles struck against my back, useless weight that I could not make myself abandon.

Behind me, the pursuit grew louder. It was no longer only breaking branches. Heavy footfalls shook the ground, accompanied by the crash of young trees being forced aside.

Whatever restraint the creature had shown earlier was gone. It was coming for me with terrible purpose.

I risked one glance over my shoulder. A huge dark shape moved through the trees parallel to the road, flowing between the trunks with unnatural grace. It kept pace effortlessly, vanishing behind one pine only to reappear closer beside the next.

My boot caught an exposed root crossing the track. I stumbled and nearly fell. That single break in rhythm cost me. The creature changed direction and crashed towards the road.

I ran harder, ignoring the fire in my muscles and the stabbing pain beneath my ribs.

The road curved, hiding the tree line where I had last seen it. For several precious seconds I could neither see nor hear the creature, and hope flared in my chest.

Then it burst on to the road behind me.

I did not look back. I could not. Its footsteps told me everything. It was running upright, each stride covering twice the distance of mine.

Morning light filtered through the trees and cast shifting shadows across the track. In any other circumstances it would have been beautiful. Now it only reminded me that I might not live to see another daybreak.

The creature's breathing reached me, deep and ragged, unlike any sound a human or animal throat should have produced. A low, wet growl accompanied each exhalation, like stones grinding together beneath water.

My own breath came in painful gasps. I could not sustain the pace much longer. My vision narrowed until the gravel ahead became my entire world.

One foot in front of the other.

Keep moving.

Do not stop.

The Glenmore access gate had to be near. A kilometre, perhaps two. I had lost any reliable sense of distance or time. My world had contracted to the space between my back and the thing pursuing me.

I caught glimpses of it at the edge of my vision, a massive shape moving with impossible speed. Sometimes it was on the road. Sometimes it crashed through the forest alongside me.

It was playing with me. It could have caught me already if it had wanted to.

My boot struck loose gravel. This time I could not recover.

I fell hard and slid across the rough surface. Pain burst through my palms and knees as the stones tore my skin. Both rifles came free and clattered away, spinning across the track.

I tried to rise, but my body betrayed me. My legs buckled, the muscles seizing after being driven beyond endurance. I managed only to roll over and sit up to face what was coming.

The creature stood about 20 metres away, motionless in the centre of the road.

In the clear morning light, I saw it properly for the first time. It stood approximately 2.7 metres tall on two legs, its body covered in dark, matted fur. Its shoulders were impossibly broad. Its arms hung well below its knees and ended in long fingers shaped like knives.

The face froze my blood. Its structure was almost human, but every proportion was subtly and horribly wrong. Its eyes regarded me with unmistakable intelligence and malice.

We stared at one another for what felt like an eternity.

Its chest rose and fell with exertion, though nothing like my own desperate heaving. It tilted its head and studied me where I sat helpless on the gravel.

I knew I was going to die. I did not merely suspect or fear it. I knew with absolute certainty.

This thing had hunted and killed my entire team, and now it was my turn. There was nowhere left to run, no weapon within reach and no hope that rescue would arrive in time.

The creature took one step towards me, then another. Despite its immense bulk, it moved with fluid, almost graceful control.

I could not look away from its eyes. They should not have existed in nature. They understood exactly what it was doing.

My hand found a stone beside me. It was a pathetic weapon, but my fingers closed around it. If I was going to die, I would not do so cowering.

The creature stopped again, now only 9 metres away. Its head tilted in the opposite direction. Its mouth, a lipless cut filled with too many sharp teeth, opened slightly.

The sound that emerged turned my blood to ice.

It was not a growl or roar. It might once have been words, mangled beyond recognition but carrying the unmistakable cadence of human speech.

I raised the stone, my arm shaking with exhaustion and terror.

The creature stepped forwards.

Then, from somewhere behind me, came the sound of engines.

The roar grew louder as I sat frozen on the gravel, the stone clutched uselessly in my hand. The creature paused and turned its misshapen head towards the noise. For an instant, indecision flickered in those unnaturally intelligent eyes.

I seized the moment and scrambled backwards on my hands and feet, pushing through the pain in my torn palms and knees.

The creature's attention snapped back to me. Its lipless mouth opened in something between a snarl and a grimace.

Three marked Police Scotland and national park response vehicles rounded the bend, tyres throwing gravel as they accelerated towards us. The lead Land Rover Discovery skidded to a halt about 45 metres away.

Doors opened and authorised firearms officers and wildlife-control personnel emerged with weapons raised.

The creature hesitated. It looked from me to the responders and back again, as though calculating its options. Then it flowed into the forest with astonishing speed and disappeared between the pines.

I tried to stand, but my legs collapsed beneath me. I turned towards the vehicles and waved frantically.

"It's coming back," I shouted. My voice was a hoarse wreck. "It's still out there."

Alastair Reid emerged from the lead vehicle carrying a police-issued shotgun under the direction of the firearms commander. His eyes widened when he recognised me.

"Mercer? What the hell happened?"

He ran towards me while scanning the tree line.

"My team," I gasped. "All dead. That thing took them. It hunted us."

Four authorised firearms officers spread into a defensive line, rifles trained on the woods. Scottish Ambulance Service clinicians remained near the vehicles with a stretcher and equipment ready.

"Where are the others?" Alastair demanded, urgency tightening his voice.

Before I could answer, a tremendous crash came from the tree line. Pine boughs shattered as the creature burst through them, abandoning stealth for speed and charging towards us.

In the clear morning light, everyone saw it.

It was nearly 2.7 metres tall, covered in matted dark fur, with arms unnaturally long and fingers ending in curved claws. The face was worst of all: almost human in structure, but horribly wrong, as though something had attempted to shape human features without understanding them.

"Fire!" the firearms commander ordered.

The officers fired in controlled succession. Bullets struck the creature's chest and shoulders, spraying dark fluid from the wounds. It staggered but did not fall. Its roar seemed to shake the air around us.

Alastair's shotgun boomed, the shot catching the creature where a human throat would have been. More black fluid sprayed, but it continued forwards, now less than 30 metres from the defensive line.

The officers kept firing, disciplined and methodical despite the nightmare charging them. Shock was plain on their faces. They had been dispatched for a possible escaped or illegally released bear, not something that remained upright under shot after shot.

After several seconds of sustained fire, the creature finally responded to its wounds. It slowed and stopped roughly 20 metres from the line. Its massive chest heaved. Black fluid oozed from numerous entry wounds.

For one moment, it fixed its gaze on me.

I saw something impossibly ancient in its eyes. Not rage or pain, but cold calculation, more chilling than any animal fury.

Then it turned and bounded back towards the forest, moving with shocking speed despite its injuries. It vanished among the trees before the officers could safely adjust their aim.

"Hold your positions!" the firearms commander ordered when one officer shifted forwards. "No one enters those trees."

My legs finally failed, and I collapsed on the gravel. The ambulance clinicians moved in as soon as the immediate threat had passed.

"Four men dead," I told Alastair as they reached me. "Colin, Ewan, Martin and Gareth. All gone. It took them. It stalked us. It knew what we were doing."

Alastair knelt beside me while the clinicians checked my observations.

"We'll find them, Andy. More teams are coming."

"No." I seized his arm with strength I did not know I had left. "No more people in those woods. It is still there. It learns. It adapts."

The clinicians eased me on to a stretcher. One inserted a cannula while another covered me with a blanket. Shock set in as the adrenaline ebbed, and my body began to tremble uncontrollably.

"We found Chloe Bennett," I continued, desperate to tell them everything before medication or exhaustion silenced me. "It put her in a tree. Displayed her. We lowered her and sealed her in a recovery bag. We cached her beneath a secured tarpaulin between two fallen trees when we had to move. The grid reference is logged on my GPS."

Alastair nodded sharply. "We'll recover her."

"And it used Gareth's radio. It imitated Ewan's voice after it took him."

Alastair's expression changed subtly. I knew that look: the careful neutrality of someone trying not to challenge a traumatised man's account.

"We'll take a full statement when you're stable," he said. "Right now you need medical treatment."

They loaded me into the ambulance. Through the open rear doors, I saw Alastair helping to organise the responders into defensive positions around the Glenmore access gate and visitor-centre car park. No one turned their back to the forest.

Whatever he believed about my account, he was taking the immediate danger seriously.

"The park," I said as a clinician prepared to close the doors. "You need to shut the whole park."

Alastair looked back at me, his face grim. "Already done. No one is entering until we understand what happened to your team."

The doors closed. The ambulance pulled away from Glenmore towards Raigmore Hospital in Inverness.

I closed my eyes, but I could not escape the images burnt into my memory: Colin snatched from the second camp, Ewan's sacrifice, Martin and Gareth dragged through the windows, and always those eyes watching with terrible intelligence.

Raigmore Hospital on 30 July 2026 became a blur of bright lights, concerned faces and medical terminology. Staff treated the lacerations to my palms and knees, severe dehydration, exhaustion and the bruising caused by repeated falls through rough forest terrain. There was nothing they could do for what I had seen or what I knew.

"Multiple impact injuries consistent with falls during flight over woodland terrain," I heard a doctor dictate. "Patient showing acute stress reaction and probable traumatic shock. Psychiatric assessment recommended after stabilisation."

Hours later, I lay in a private room with fluids dripping into my arm and monitors sounding quietly beside me. The sedatives dulled the edge of my terror but could not erase what I had witnessed.

Alastair Reid visited that evening. He stood awkwardly at the foot of the bed, holding his national park identification wallet in both hands.

"How are you feeling?" he asked.

"As though I watched my entire team die and escaped by chance," I replied.

He nodded and glanced towards the door to make certain we were alone.

"Specialist teams are going in tomorrow if conditions permit. Police Scotland, wildlife-control personnel and further armed support. Whatever that thing was -"

"Is," I corrected. "Whatever it is, it is still out there."

"Right." He shifted uncomfortably. "The problem is, Andy, that the official report has to be manageable."

I knew exactly what he meant.

"You're writing it off as a bear attack."

"We can hardly file an official report about a 2.7-metre humanoid creature that shrugged off rifle fire," Alastair said, lowering his voice. "The national park authority, Police Scotland, the Scottish Government - none of them wants panic. And frankly, no one would believe it."

"You saw it," I reminded him. "The wildlife-control officer saw it."

"What we saw was unclear in the chaos, among the shadows of the forest."

He could not meet my eyes.

"Bullshit."

My voice was quiet but hard.

"You know what you saw."

Alastair ran a hand through his hair.

"Four members of your team are missing. For now, we're treating it as a search-and-recovery operation. As for Chloe Bennett..." He paused. "We recovered her body from the grid reference you gave us. The forensic pathologist's preliminary finding is consistent with an exceptional wildlife attack. The public explanation will most likely be an escaped or illegally released bear."

I gave a bitter laugh that made him flinch.

"And when you don't find whatever is left of my team? When more hillwalkers disappear in the Unnamed Glen?"

"We've closed the area indefinitely for wildlife management," he said. "That's the best I can do at present."

He left Raigmore Hospital soon afterwards, promising to visit again and tell me what the specialist recovery teams found. We both knew it was an empty promise. Whatever they discovered, the official account would not change.

Alone in my hospital room on 30 July 2026, I stared at the ceiling and thought about my team.

Colin's confident smile as he flew us towards the Unnamed Glen. Ewan's quiet competence as he tracked through impossible terrain. Martin's steady hands as he treated our injuries. Gareth's technical skill, keeping us connected to control.

All gone. All lost to something that should not have existed.

The doctors said I would make a full physical recovery. They recommended prolonged therapy for post-traumatic stress and suggested that I take an extended break from mountain-rescue work. They spoke carefully around what I had told them about the creature, never directly contradicting me but never acknowledging the truth either.

As night fell over Inverness and the hospital grew quiet, I made a decision. If the official channels would not acknowledge what lurked in those mountains, I would find another way to warn people.

I would gather evidence, find others who had encountered it and build a case too strong to ignore.

Because the creature was still out there, watching, waiting and learning. Until someone told the truth about what was hunting in the Cairngorms, more people would disappear into the Unnamed Glen and never return.
