The Hole in Blackwood Forest

I stood inside the Upper Feshie ranger post in the Cairngorms National Park, looking through the windows at miles of Caledonian pinewood. The morning mist was beginning to lift, revealing the crowns of Scots pines and birches that had been there long before me. I had worked as a ranger for ten years, and I still loved that view every morning.

The radio crackled with routine check-ins from other rangers. I picked it up, confirmed my position with the regional duty-control room, then set it down again. My mind was not on the day's patrol route or the walkers expected along the South Glen path. I was thinking about my brother.

Owen was the reason I wore the ranger-service uniform.

Four years older than me, he had been dragging me into the hills and woods since I could walk. "The forest will teach you more than any classroom," he used to say, his rucksack always waiting beside the door for our next expedition. Whilst other children played computer games, we tracked red deer, built shelters from fallen branches and learnt which wild plants were safe to eat.

I ran my hand across the worn surface of my desk and touched the small wooden pine marten Owen had given me when I got the job. He had carved it during a two-week survival exercise, whittling by firelight after dark.

"Something to watch over you when I can't," he had said, pressing it into my palm.

The memory tightened my throat.

Our parents died when I was nineteen. Their car left a Highland pass during a storm. The official report blamed a steering failure, but at the time I had not cared about the details. All I knew was that one telephone call had changed everything.

Owen was twenty-three and already serving with the Royal Marines. He came home immediately and moved back into our parents' house, where I was still living whilst attending a local further-education college.

"What do you want to do now?" he asked one night, about a month after the funeral.

We were sitting on the back step, passing a bottle of Dad's whisky between us. I had no answer. Without Owen, I might have been lost.

Instead, he carried me through the worst of the grief. He arranged compassionate leave, followed by a temporary shore posting that kept him near me for several months. We walked in the hills every weekend, sometimes talking about Mum and Dad and sometimes saying nothing at all. The forest absorbed our silence. It gave us room to breathe when the house felt too crowded with memories.

By the time Owen returned to his usual duties, I had decided to become a ranger. He nodded when I told him, as though he had known all along where I would end up.

Whilst I found my place among the pines, Owen progressed through the Royal Marines and later into a sensitive specialist unit whose precise work remained classified. He never spoke much about it. I knew that his training included survival in extreme environments, reconnaissance and rescue, but little more.

Sometimes months passed with only a few brief messages sent through secure service channels. Then he would appear at my tied cottage without warning, looking older than he ought to have done but still wearing the same steady expression.

I crossed to the Ordnance Survey maps pinned to the wall and ran my fingers over the familiar mountains, corries, glens and pinewoods. The Cairngorms were immense, and Blackwood Forest, an isolated tract in the western part of the national park, contained country rough enough to swallow anyone who did not know what they were doing.

It was easy to become lost there. Easier still to disappear if you meant to.

The last time I had seen Owen before his disappearance was three years earlier, during a rare three-week leave. We had planned a long walk through one of the most remote parts of the high country. I remembered how different he had seemed. He was still fit and capable, but there was a new tension in his shoulders. He watched our surroundings constantly in a way I had never noticed before.

Five days into the trip, we camped beside a small lochan. The night was clear, and the stars shone on the water. Owen had been quiet for most of the day, but as we sat beside the fire, he finally began to talk.

"Do you ever think about how much of the world remains unmapped, Daniel? Not just physically. In other ways."

I prodded the fire and sent sparks spinning upwards. "What do you mean?"

"There are things I've seen on deployments. Things that don't make sense." He stared into the flames. "Places where the rules seem different."

"What sort of places?"

He shook his head. "I can't discuss specifics. But there are corners of wilderness all over the world where local people refuse to go. Places with histories of disappearances stretching back centuries."

I laughed it off. "Sounds as though you've heard too many ghost stories in camp."

Owen did not laugh. He took a long drink from his water bottle and looked into the darkness beyond the fire.

"Maybe." He paused. "Have you ever noticed anything strange in your part of the park? Places where animals won't go? Unusual patterns in their behaviour?"

"No," I said, although I had never deliberately looked for such things. "The park's well documented. We know what's out there."

"Do we?" He gave me a look I could not read. "There are gaps in our knowledge, Dan. Things we've forgotten, or chosen not to see."

I changed the subject, assuming he was exhausted or troubled by whatever secret work he had been doing. But for the rest of the trip, I caught him looking behind us more than once. He watched the trees as though he expected something to emerge from them.

That memory felt different now, as I stood in the ranger post. Had Owen known that something was wrong in Blackwood Forest? Had he been trying to warn me in the only way he could?

I returned to my desk, sat down and pulled the day's duty roster towards me. The ranger service was stretched thin. Most staff worked around popular paths, visitor centres and car parks. The remote pinewood and high corries might receive a ranger patrol only once a week, sometimes less in bad weather.

Owen knew the Cairngorms almost as well as I did. If he had wanted to investigate something unseen, he would have known exactly where to go.

The thought unsettled me, although I could not have said why. I picked up the pine-marten carving and rubbed my thumb over its smooth wooden back.

My brother was not an inexperienced walker who might stray from a path and become confused. He was a Royal Marines specialist, trained to navigate and survive in conditions that would defeat most people, including many rangers. Owen could have lived in the wild for as long as necessary.

So what could make a man like him disappear?

The question had no answer. I put the carving down and reached for my rucksack. I had work to do, paths to inspect and walkers to keep safe. Beyond the windows, the ancient forest waited beneath its canopy, keeping its secrets.

The telephone had rung at 06:17 on Tuesday, 12 August 2025. I remembered checking my watch as I lifted the receiver, assuming the night controller wanted to pass on an update.

"Mercer," I answered, suppressing a yawn.

"Daniel, it's Callum Fraser in duty control. We've got a situation."

His voice had the careful tone people used when delivering bad news.

"Your brother missed his scheduled check-in last night. His route card said he would finish on the Glen Feshie path before sunset."

The last traces of sleep vanished. Owen never missed check-ins. Not once in all our years in the hills. It was a rule we both lived by.

"When was his last confirmed location?" I asked, dragging on my boots with my free hand.

"Three days ago, at the Upper Feshie ranger post. He signed the intentions book and said he was going to explore some of the feeder burns above the Allt Dubh. He expected to be out for four days."

I pulled an OS map from the wall and found the Allt Dubh catchment. It was remote, a tangle of ancient pinewood, bog, broken ridges and narrow glens with little maintained access. Owen had chosen his ground well if he wanted solitude.

"I'm heading there now. Ask Police Scotland about air support, and ring Iain MacLeod at Cairngorm Mountain Rescue."

"They've already been notified. Iain is assembling a team." Callum paused. "I'm sure Owen's all right. He may simply have been delayed."

Neither of us believed it. Owen Mercer did not casually miss an agreed time. He was more likely to arrive early than late.

Something was wrong.

Within an hour I was at the Upper Feshie post, examining the intentions book myself. Owen's handwriting was unmistakable:

O. Mercer. Solo route. Allt Dubh feeder burns. Four days.

There was nothing unusual in the entry. No concealed warning or clue.

By midday, twenty-three people had assembled: mountain-rescue volunteers, Police Scotland officers, rangers and specialist search personnel. I spread Owen's planned route map across the bonnet of my Land Rover Defender.

"He intended to follow this feeder burn towards the headwaters, then cross the ridge and examine the next glen," I said, tracing the route with one finger. "He's an experienced Royal Marines survival specialist. Standard assumptions about a lost walker may not apply. We need to think differently."

Iain MacLeod nodded. At fifty-two, he had led Cairngorm Mountain Rescue operations for longer than I had been a ranger.

"We'll divide into five teams and make radio checks every hour. Police Scotland is coordinating the missing-person operation. HM Coastguard aircraft will be available tomorrow morning if the weather holds."

That first day we covered roughly twenty-four kilometres of punishing terrain between us, calling Owen's name until our voices became raw. The teams carried thermal imagers, binoculars and tracking equipment. We found nothing. No abandoned kit, no boot prints and no broken vegetation suggesting that anyone had passed.

As darkness fell, we established a temporary base and prepared to resume at first light. I barely slept. I stared at the stars through gaps in the branches and remembered Owen teaching me the constellations on childhood camping trips.

"If you ever get lost," he had told me when I was ten, "find Polaris. Then you'll know where north is."

Morning brought the promised aircraft, two HM Coastguard search-and-rescue helicopters fitted with thermal cameras. They flew systematic patterns over the glens whilst we continued searching on foot.

By the third day, the operation had expanded to forty-five people. More mountain-rescue volunteers had arrived, along with additional Police Scotland personnel, specialist search-dog handlers and rangers from neighbouring areas.

On the fourth day, four of Owen's former unit colleagues appeared. They wore ordinary outdoor clothing but moved with the same quick, alert economy I had seen in my brother. All were ex-Royal Marines personnel. Most gave only their first names, and I knew better than to press for details.

The oldest was a weathered man named Ross Kerr.

"We served with Owen," he said. "Heard he'd gone missing on your ground."

"Thank you for coming," was all I managed.

The relief I felt was enormous. These men understood Owen's abilities and the way he thought. They joined our teams, but also carried out searches of their own, sometimes disappearing for hours before returning to the main group. I suspected they were using equipment or methods beyond ordinary mountain-rescue resources.

A week into the operation, we had searched Owen's declared route and extended the grids about eight kilometres in every practical direction. Finding nothing was beginning to tell us something.

People did not simply disappear without leaving evidence.

I called a meeting at the temporary base. The people gathered around me were exhausted. All of them had put their ordinary lives on hold to help find my brother.

"We need to consider other possibilities," I said. "Either Owen departed radically from his planned route, or something prevented him from leaving a trail."

Ross spoke from the edge of the group. "We've requested restricted reconnaissance imagery from the dates he was out here. Some former unit contacts may be able to get it unofficially. It might give us something."

Two days later, the imagery arrived. We crowded around a laptop as Ross moved through the files. The resolution was good enough to distinguish clearings, burns and shelter-sized objects, but nowhere near good enough to identify an individual walker.

"This was captured the day before Owen was due back," Ross said, pointing to a clearing beside a bend in the Allt Dubh. "There's a small anomaly here that isn't present in the previous image."

We enlarged it until the landscape dissolved into square pixels. A dark mark showed in the clearing, perhaps the size of a small tent or tarpaulin shelter.

"That's nearly five kilometres east of his planned route," I said, marking the position on my map.

We went immediately, a team of twelve that included Ross and another of Owen's former unit colleagues.

The clearing appeared untouched when we arrived. There was no tent, no camp and no obvious sign that anyone had been there. Ross crouched near the centre and sifted pine needles and damp soil through his fingers.

"The ground's been disturbed recently."

He looked up, his face unreadable. "Search the perimeter."

We found it ten minutes later: a single boot print, partly preserved in mud beside the burn. Its tread matched Owen's walking boots.

The print pointed towards the water, then the trail ceased as though Owen had stepped out of the world.

The discovery gave the search new urgency. We expanded outwards from that one mark and brought in Police Scotland specialist search dogs. The dogs showed interest in the clearing but could not establish a continuous trail. Again and again, they caught a scent, followed it for a few metres and then lost it completely.

Two weeks into the operation, Inspector Morag Sinclair, Police Scotland's mountain-rescue search adviser, drew me aside.

"Daniel, we need to discuss scaling back."

I had known the conversation was coming. Search resources were finite, and two weeks was already a long deployment, but I was not ready to hear it.

"He's out there," I said. "Owen wouldn't give up on me."

Inspector Sinclair rested a hand on my shoulder.

"We're not giving up. We do need to become more targeted. I can keep a smaller team active and concentrate on priority areas, but we can't sustain the operation at this scale."

Half the searchers left the next day. By the end of the third week, only a core group of rangers, mountain-rescue volunteers and Owen's former colleagues remained. The Coastguard helicopters were reassigned to other emergencies. Media coverage dwindled to occasional updates.

During the fourth week, Ross found me sitting alone beside the base-camp fire.

"The formal search is being suspended tomorrow," he said without preamble.

I nodded. Fiona Grant, my area manager, had already sent me the notice from the ranger-service offices.

"What do you think happened to him?" I asked.

Ross was silent for a long time.

"Owen was the best of us. If he didn't want to be found, even we might not find him."

"You think he disappeared deliberately?"

"I didn't say that."

Ross stood. "We're staying for a few more days, unofficially."

Eventually, even they left.

After six weeks, I found myself alone at the makeshift command post, surrounded by maps covered with search grids and handwritten notes. Fiona had been sympathetic but firm. I had to return to ordinary duties. The investigation into Owen's disappearance would remain open, but searching for him could no longer be my full-time work.

I did not accept that.

Instead, I used all the annual leave and time off I had accumulated, establishing the pattern that defined the following months: four days working as a ranger, then three days searching for Owen. Every weekend, every public holiday and every spare hour went into combing the Allt Dubh country.

I slept beneath the same stars Owen might have been seeing if he was alive. I learnt every Scots pine, granite outcrop, peat hag and seasonal burn in that glen. Autumn rains swelled the watercourses. Winter snow covered the high ground, then shifted beneath gales and revealed it again. I inspected the banks after every thaw, hoping floodwater might uncover something.

Storms brought lightning and occasional fires in the drier stretches of pinewood. Each time I hurried to the affected ground, half hoping the disturbance might force Owen out if he was hiding. Each time I returned alone.

The worst part was the complete absence of evidence. People left hair, skin cells, dropped equipment and waste. Even if Owen had suffered a fatal accident, there should have been something.

As the months passed, I began researching other disappearances in the Cairngorms. There were not many, perhaps one troubling case every few years, but some had peculiar similarities: experienced walkers vanishing from remote country, few or no clues, searches reduced after several weeks.

I kept a journal of facts, suspicions and increasingly unlikely theories.

An animal attack seemed implausible without blood, damaged equipment or remains. Abduction in such inaccessible country was difficult to imagine, especially given Owen's training. A voluntary disappearance was possible, but why would he do it? And how could he have left no trail?

The questions consumed my life. I lost weight, slept badly and became short-tempered with colleagues. Fiona suggested counselling. I attended just often enough to keep my job.

Six months after Owen vanished, I sat in the clearing where we had found his lone boot print, long since washed away by rain and meltwater. The light was fading. I should have returned to my camp, but I could not make myself move.

"Where are you?" I asked the silent forest.

The trees gave me no answer.

When I finally stood, a thought that had been growing for months came fully into focus. The lack of evidence was not merely strange. It was impossible. It contradicted everything I knew about tracking, survival and human behaviour.

People did not vanish without trace. Not even someone with Owen's skills could erase himself so completely.

Unless someone, or something, had taken him.

The idea should have sounded mad, the product of grief and exhaustion. Instead it felt horribly right, as though a shape hidden in darkness had suddenly moved beneath a sheet.

I shouldered my rucksack and walked back to camp, using my torch as the forest darkened. For the first time in months, I felt that I had the beginnings of a plan. I still did not know what had happened to Owen, but I was beginning to understand what had not happened.

On 15 March 2026, rain hammered against the windows of my tied cottage and kept pace with my racing thoughts. A violent Atlantic front had settled over the western Cairngorms. Water streamed down the panes, obscuring Blackwood Forest beyond the rear garden.

I sat at my desk and stared at my laptop, reading the same message until the words seemed branded into my vision.

From: Owen Mercer's secure mailbox Date: 15 March 2026, 21:46 Subject: I'm alive

Dan,

I'm alive, but I'm trapped. There's a hole in Blackwood Forest. It isn't natural. I can't get out on my own.

OS grid reference NN 812 946.

Come alone. Trust no one. Not the rangers, not the police, not even my former unit contacts. They wouldn't understand what's happening here.

Owen

Owen had been missing for seven months, ever since 12 August 2025. Now this message had appeared from nowhere.

My hands shook as I checked the time again. It had arrived exactly three minutes earlier. I clicked Reply and typed as quickly as I could.

Owen, where have you been? Are you hurt? I'm coming for you. Tell me more about the location.

I sent it, then held my breath. No answer came. After five minutes of refreshing the inbox, I forced myself away from the screen and tried to think.

It might be a cruel hoax. Someone might have compromised Owen's account. Or it could genuinely be my brother reaching out after seven months of silence.

I needed to know whether the message was real.

I opened the full email headers and tried to trace its route. My technical knowledge was limited, but Owen had taught me enough to recognise deliberate obfuscation. The message had been routed through servers in Japan, Germany and Canada before the trail reached an apparent dead end. That degree of care was consistent with him.

Next I spread my Ordnance Survey maps across the floor. NN 812 946 lay in Blackwood Forest, in extremely rough country roughly forty-eight kilometres from the Allt Dubh search area. Contour lines crowded one another around steep glens, broken slopes and peat-choked hollows. The nearest practical approach ended many kilometres away.

I knew the wider district from training exercises. It contained rock fissures, narrow corries and old mine or estate workings, but I could not recall any hole capable of trapping someone with Owen's skills for seven months. British Geological Survey records showed no major cave system at the grid reference.

The message did not make sense. But if there was even the smallest chance it came from Owen, I had to act.

I picked up my mobile and rang Callum Fraser.

"Callum, it's Daniel Mercer. I need a favour."

"Daniel, it's nearly ten at night. Is everything all right?"

"I need to know whether there's been unusual activity on Owen's accounts. Banking, social media, secure email, anything that can be checked legally."

There was a pause.

"Is this official business?"

"No," I admitted. "But I wouldn't ask if it weren't important."

Callum sighed. "Give me a day. I may be able to speak to someone in digital forensics."

"I need it tonight."

Another pause followed.

"I'll ring you back."

Whilst I waited, I searched the ranger-service logs for unusual incidents around that part of Blackwood Forest. I found nothing significant in patrol records or reports from walkers. Then I moved into historical material.

Old Gaelic estate accounts and fragments of local oral tradition contained vague warnings about Glen Dubh and Coire Cailleach. Shepherds had supposedly kept away from certain sections of the pinewood, even when livestock strayed there. None of the accounts explained why.

Buried in an estate catalogue was a reference to a 1920s expedition led by Edward Mercer, my great-grandfather. Its journals were listed as missing. Later summaries dismissed the party's claims as confusion caused by exposure, yet the original testimony and most of the supporting correspondence had vanished from the archive.

Another catalogue entry referred to a 1943 estate report by Warden Alastair Reid, but the report itself was absent. Only its cover description survived: Unauthorised access, Glen Dubh. Ground disturbance and missing persons.

It felt less like ordinary poor record-keeping than an old, institutional habit of suppression.

My mobile rang forty minutes later.

"Daniel, it's Callum. I spoke to someone who knows digital forensics. As far as they can establish, Owen's other accounts have shown no activity since he disappeared. No authenticated log-ins and no transactions. The mailbox has continued receiving messages, but that doesn't prove anyone opened or read them. There was no authenticated access recorded until the routed outgoing message tonight."

I thanked him and ended the call.

Only then did Owen's warning return to me with its full force: Trust no one.

I had already involved Callum and, indirectly, someone with access to digital-forensics systems. Perhaps that was harmless. Perhaps I had just announced to the wrong people that Owen was alive.

I opened my notebook and recorded everything I knew about NN 812 946. The location stood at roughly 945 metres above sea level. The nearest established path ended about thirteen kilometres away, and the last approach crossed severe, largely pathless terrain. In March there would be snow on shaded slopes and ice in the corries.

It would not be an easy journey, even in good weather.

Rain struck the windows harder, and occasional lightning turned the cottage stark white. I opened the secure cabinet and began assembling my equipment. If I was going, I had to prepare properly. Owen had taught me that careful planning saved lives.

First came warm base layers, insulation, waterproofs, spare socks, gloves and a hat. I packed my ranger-service uniform at the bottom of the rucksack in case I needed to establish my identity.

Then came tools: a knife, multi-tool, head torch and hand torch with spare batteries, fire-lighting equipment, OS maps, compass and handheld GPS receiver. I added three days of high-energy food, water-purification tablets, an emergency shelter and a comprehensive mountain first-aid kit.

I packed fifty metres of strong cord and sixty metres of certified climbing rope, along with slings, karabiners and a harness. I added my satellite handset and ranger radio, although neither could be trusted in the deepest glens.

Finally, I unlocked the separate rifle safe and removed my legally held bolt-action deer rifle. It was normally used only for authorised deer management, never as routine rescue equipment. I cleaned it, checked it and packed it securely with a limited supply of ammunition. I could not explain why I thought I might need it, but the thought of entering Blackwood Forest alone and unarmed felt worse.

As I checked an old estate map against my proposed route, I noticed a derelict forestry store marked several kilometres from the coordinates. A handwritten annotation from the 1960s mentioned a sealed blasting cache left after an abandoned drainage and track-cutting project. If anything remained there, it would be dangerously unstable and illegal to disturb. I marked the site only as a potential hazard to avoid.

The methodical work kept my hands busy whilst my mind circled Owen's message. What sort of hole could hold him? Why had he warned me against the same former colleagues who had helped search for him? Why contact me only now, after seven months?

I had no answers. Beneath the confusion, however, something I had almost forgotten began to grow.

Hope.

For the first time since Owen vanished, I had something concrete: a message in his manner, sent through channels he might have used, and a precise OS grid reference.

By 03:00, my rucksack was ready. I sat at the kitchen table with coffee from the cafetiere and wrote a note to Fiona Grant. I could not tell her the truth. She would either stop me or organise a formal response. Neither option was compatible with Owen's instruction to come alone.

I wrote:

Fiona,

I need to take personal leave immediately because of a family situation. I expect to be unreachable for three to five days and will make up any missed shifts when I return.

Daniel Mercer

I had accumulated enough goodwill over ten years for her to accept that for a few days, although she would not be pleased. By the time anyone became seriously concerned, I would either have found Owen or...

I refused to complete the thought.

The storm eased towards dawn. The forecast promised improving conditions later that day, followed by three relatively settled days before another front arrived. It was not ideal, but I had worked in worse weather during mountain-rescue operations.

I entered NN 812 946 into my handheld GPS receiver and checked the result against the OS maps and compass bearings. My plan was to drive east and south to the Linn of Dee car park, then use the path network for the first stage before leaving it for a long, difficult crossing of remote pinewood and high ground. Given the terrain, I expected the journey to take two full days.

As I finished, I noticed the little wooden pine marten Owen had carved. I picked it up and felt its familiar shape settle into my palm. After a moment's hesitation, I slipped it into my jacket pocket.

Something to keep him close.

Dawn was breaking through the clouds when I locked the cottage. The rain had stopped, leaving the air sharp with wet earth, peat and pine. It was the smell of the wild country Owen and I had always loved.

I loaded my equipment into the Land Rover Defender, secured the rifle out of sight and climbed into the driver's seat. Before pulling away, I looked at the cottage in the rear-view mirror.

If the message was real, everything would change.

If it was not, I pushed that thought aside as well.

I drove down the forestry track to the A9, followed the road towards the mountain access routes and eventually reached the Linn of Dee car park. There I parked, transferred the rifle and the rest of my equipment into my rucksack, recorded a deliberately vague route in the intentions system and began walking west through the path network.

The maintained path fell behind me later that morning as I turned towards unmarked country. My boots sank into waterlogged peat and deep moss that might not have held another human footprint for years.

The GPS receiver showed just over thirty kilometres to Owen's coordinates by a straight line, though the ground would force me to cover considerably more. I kept a steady, purposeful pace. Mist hung between the ancient pines, turning everything grey and muting the forest sounds. The rucksack dragged at my shoulders, heavy with everything I might need to rescue my brother from whatever waited at the hole.

"I'm coming, Owen," I whispered.

The vast pinewood swallowed the words.

By midday I reached the first serious obstacle, a steep ravine roughly ten metres deep with a swollen burn at its base. In summer I could have crossed without much difficulty, but the March rain had turned the water into a brown, violent torrent.

I spent nearly an hour working upstream before I found a fallen Scots pine spanning the gap. I tested the trunk carefully before committing myself. Its bark was slick with rain and lichen, but the wood felt sound.

Owen's voice returned to me as I edged across.

"Three points of contact, Dan. Hands and feet working together. That's what keeps you alive."

The terrain became harder as the day wore on. The Cairngorms high country was unforgiving: peat bog, hidden burns, granite boulder fields, steep corries and forests old enough to conceal their shape from a map. The climbs grew sharper, and my thighs burned as I forced a way through juniper and young birch.

That night I camped beneath a rocky overhang. I ate cold food rather than lighting a fire. Owen's warning had made me wary of leaving any obvious sign of my presence.

I spread my sleeping bag on the hard ground and lay awake for hours, listening to the ordinary sounds of the forest: wind stirring pine needles, the distant bark of a fox and something small moving through heather. Stars appeared between the branches whenever the clouds broke.

Morning brought light rain and colder air. I packed quickly, forced down an oat bar and resumed the journey. The GPS showed just under twenty kilometres remaining, but in that terrain it meant another full day.

The forest changed as I walked.

The Scots pines became larger and older, their trunks thick and twisted, their crowns flattened by centuries of wind. Yet the undergrowth thinned despite the abundance of water and filtered light. There was less birch, less juniper and almost no rowan. It was as though nothing wished to root there.

Then I noticed the birds disappearing.

At first it was only a sense that something had changed. Eventually I realised that I had not disturbed a grouse or heard a capercaillie, crossbill or thrush for hours. I saw no red squirrels on the trunks and found no fresh deer sign in the soft ground.

During the afternoon, I encountered several strange arrangements of granite. They were not natural outcrops but rough rings, each about two metres across. They resembled the remnants of shielings or old estate boundaries, except that the stones appeared freshly placed. Their exposed surfaces were clean, with no lichen, moss or signs of weathering.

I photographed the rings with my mobile and marked their position on the GPS receiver. If I returned, I told myself, I would report them for proper examination.

The day stretched on. I crossed three feeder burns, passed through pinewood scarred by an old lightning fire and negotiated a field of immense granite boulders left by retreating ice. My legs were exhausted, but the thought of Owen waiting drove me forwards.

Late in the afternoon, the GPS showed less than two kilometres to NN 812 946.

The forest had become unnaturally quiet.

No birds sang. No squirrels chattered. I could not hear the buzz of an insect. There was only my breathing and the wet crush of my boots on fallen needles.

The pines were the largest I had ever seen, exceptional remnants of the ancient Caledonian forest. Their trunks were wider than the bonnet of my Defender, and their massive branches interlocked overhead until the forest floor lay in premature dusk.

I should have recognised the country. After ten years as a ranger, I thought I knew the western Cairngorms, even their least visited reaches. Yet nothing around me corresponded properly with the OS map. The angle of the slopes seemed wrong. The burns did not lie where the contours said they should. Even the light entered the trees at an impossible slant.

It felt as though I had walked into a part of Blackwood Forest that did not exist on any map.

The GPS receiver gave a soft tone. Five hundred metres remained.

I slowed and moved with greater care, searching for tracks, smoke, fabric or any other sign of a human presence. The hairs rose along the back of my neck.

Something was wrong with that place. I knew the feeling from years spent amongst wild animals: the instinctive terror of prey when a predator was close.

The forest opened without warning into a clearing about fifty metres across. I stopped at the edge and crouched behind a fallen trunk to observe it before exposing myself.

The clearing did not look natural. The trees around its perimeter stood too evenly apart, as though a single force had pushed them backwards to form a precise circle.

At the centre stood an ancient Scots pine larger than any I had encountered in my career. Its trunk was broad enough to conceal several men. Deep plates of grey-brown bark folded across its surface, but the upper third had been shattered and blackened by lightning.

The strike had split the trunk down the middle, leaving a jagged wound in the old wood.

I checked the GPS receiver again. NN 812 946 lay at the exact centre of the clearing, beneath that broken pine.

After ten minutes without seeing movement, I left cover and advanced with the rifle ready.

The clearing felt different under my boots. The ground was soft and spongy, less compacted than the surrounding forest floor. Nothing grew there except a mat of dark moss unlike any native species I recognised.

I circled the lightning-split pine and examined the scorched timber. The damage looked recent, perhaps less than a year old. The exposed heartwood had not begun to rot, and there were no beetles or other insects in it.

Behind the pine, partly concealed by fallen branches and splintered timber, I found the answer to Owen's message.

There was a hole in the earth.

It was a perfect circle, nearly two metres across.

I approached slowly, every instinct urging me to keep away. It was not a sinkhole, an animal burrow or an ordinary cave entrance. Its edge was too exact, as though a vast circular blade had cut through the forest floor. There was no spoil heap nearby and no scattered soil from an excavation. Despite months of Highland rain, the rim showed no erosion.

I crouched near the edge, keeping my centre of gravity low.

The interior was absolutely black. It was not the grey darkness of a cave mouth. It was a light-consuming void.

I picked up a small stone and dropped it in.

No impact came back. There was no scrape, bounce or diminishing rattle to suggest depth. The stone simply ceased to exist.

I removed my rucksack and took out the hand torch, a powerful model intended for searches across open ground. When I directed it into the hole, the beam did not fade with distance. It ended a metre or so below the rim, cut off as sharply as if the darkness were a solid surface.

"What the hell did you find, Owen?" I whispered.

I needed to learn more, but I refused to rush. I tied one end of the fifty-metre cord around the lightning-split pine, secured my spare torch to the other and switched it on. Then I lowered it into the opening.

The cord descended through five metres, then ten, then twenty. I could see the torchlight for barely a metre before it disappeared. The cord continued feeding into the dark.

After letting out roughly thirty metres, I stopped and gave it a cautious tug.

There was no sense of weight on the end.

I pulled the cord back. When it emerged, the final section had been severed with a cut as clean as a razor stroke. The spare torch was gone.

I retreated from the hole, trying to understand what I had seen.

Nothing about it was natural. Somehow Owen had discovered it, or had been brought to it, and now claimed to be trapped inside.

The light was failing. I had reached the coordinates late on the second day of my journey, and whatever decisions I made would have to wait until morning.

I withdrew about fifty metres into the ordinary pinewood, choosing ground from which I could still watch the lightning-split tree and the opening behind it. I established camp quickly and rigged my sleeping shelter between two sturdy pines rather than lying on the ground. From there I would have a better view and a quicker escape route.

I kept the fire tiny and screened, using it only to boil water and heat my food. The rifle remained within reach whilst I ate.

Night settled completely over Blackwood Forest. The circular clearing seemed faintly lighter than the surrounding trees beneath a quarter moon. At its centre, the broken Scots pine rose like a blackened spire, its shattered crown pointing into the sky.

As darkness gathered, Blackwood Forest became too quiet. There were no owls, no small creatures rustling through the juniper, not even the distant bark of a fox. The ordinary night sounds of an ancient pinewood had vanished, replaced by a heavy stillness that felt deliberate. I kept checking the bolt-action deer rifle beside me, making certain it was loaded and the safety was within easy reach. I was licensed to carry it for authorised deer management, not rescue work, but I had taken it from its secure cabinet before leaving the Upper Feshie ranger post. Now I was glad of its weight.

I pulled my jacket tighter and settled into the hammock. My body was exhausted, but my mind would not stop. Owen's words kept returning to me.

I'm alive, but I'm trapped.

There's a hole in the forest, Daniel. It isn't natural.

He had been right about the hole. Nothing about it was natural.

But what was it? How could it have trapped someone like Owen, a Royal Marines specialist trained to survive and operate in places far harsher than this?

I slept in fragments. Every snapping twig brought me awake with my hand on the rifle. I remembered something Owen had told me years before.

"Sleep lightly. Wake ready. Your life might depend on that first reaction."

I watched the stars turn through gaps in the Scots pine canopy and counted the hours. The clearing remained still. The hole lay beneath the ancient lightning-split pine, a darkness deeper than the shadows around it.

Shortly before dawn, fog rose from the damp ground and spread between the trees. It covered the clearing in white, yet the hole remained a perfect black circle. The mist curled around its rim without crossing it, as if pushed aside by an invisible current.

The first light touched the crowns of the pines, then descended slowly through the branches. Birds began calling at last, distant at first and then nearer, as though they had kept away throughout the night and were only now returning.

I climbed stiffly from the hammock. My muscles ached after two days of hard travel, much of it across bog, steep burns and pathless pinewood, followed by a night spent jerking awake at every sound.

In daylight, the clearing seemed less immediately threatening. The hole did not. It remained a flawless black disc in the forest floor.

I ate a quick breakfast, drank from my flask and organised my equipment. I had arrived late on the second day of my journey from the access point, with barely enough light to inspect the clearing before making camp fifty metres away. I had spent the first night watching. Now, on the third day since leaving the Land Rover, I could begin a proper examination.

I had found what Owen had described, but I still had no idea how he could be trapped inside it or how I might bring him back. One thing was certain: the hole appeared on no Ordnance Survey map, estate plan or British Geological Survey record I had studied. It should not have existed.

Yet there it was, swallowing light, sound and anything lowered across its edge. Somewhere beyond that impossible darkness, my brother might still be waiting for me.

The morning sun filtered through the pine branches as I opened my field notebook and sketched the clearing again. I marked the hole's position in relation to the lightning-split Scots pine and the surrounding birches. The black disc was a little under two metres across and seemed to absorb not only light but sound. Whenever I approached it, my footsteps became muffled, as though the air itself were being compressed.

"I need to be systematic," I said aloud.

My voice sounded flat in the clearing's strange acoustics.

I divided the area into a rough grid, covering the clearing and fifty metres of woodland around it. In each section I examined the ground, lifted fallen needles and branches, and searched for fibres, damaged vegetation, discarded equipment or any other indication that someone had passed through.

By lunchtime I had covered half the grid. I found nothing. There were not even animal tracks, which was extraordinary in that part of the Cairngorms. No red deer prints, no pine-marten droppings, no squirrel feeding remains. It was as if every creature in the forest avoided the place.

I stopped to eat and checked the satellite handset. It still could not establish a connection. The steep-sided glen and dense canopy made reception unreliable, but the failed call brought home how completely isolated I was. Nobody knew my precise location. Owen's message had said, "Come alone. Trust no one," and I had obeyed. If something happened, there would be no search until I failed to return.

After eating, I resumed the survey, widening my circles around the hole. The ground near it was almost bare, broken only by patches of moss. In a healthy pinewood there should have been needles, fallen twigs, decaying wood and low growth. Here it looked unnaturally clean, as though someone had swept it.

Beyond the western edge of my grid, I found the remains of an overgrown estate track. It matched a faint line on the derelict forestry map I had copied before setting out. About eighty metres along it stood a low stone store half swallowed by birch and bracken. Its roof had collapsed, but a rusted metal locker remained beneath the back wall.

The map had marked the place as an old blasting cache, left from forestry drainage and track works decades earlier. The locker was sealed with a corroded clasp. Through a split in the metal I could see waxed paper packets and the ends of several gelignite cartridges.

I did not touch them. Old gelignite could become dangerously unstable as it aged, and merely finding it should have triggered an evacuation and a call to Police Scotland. I marked the cache in my notebook and returned to the clearing, telling myself I would report it as soon as I regained contact.

Later that afternoon, I examined the hole itself. I approached carefully, remembering how its edge had severed the thin cord I had lowered the previous evening. Lying flat at a safe distance, I studied the rim.

It was perfectly circular and unnaturally sharp, without subsidence, exposed roots or any of the weathering a natural opening should have shown. I used a long-handled sample scoop to collect material from several points around it, keeping my hands well back.

The substance was unlike any soil I had encountered during ten years as a ranger. It was a fine black powder, almost like ash, with no visible roots, insects or organic matter. It felt heavier than ash and left an oily sheen on the steel scoop.

I labelled each sample with its position and sealed it in a separate container. Owen had warned me that the hole was not natural. Proper analysis might at least prove that the ground around it was anomalous.

As the sun lowered, I returned to my camp fifty metres from the clearing. I rebuilt the small fire, keeping it low and screened so that its light would not carry far. The forest had remained unnaturally quiet all day. With night approaching, I expected the ordinary sounds to return: owls hunting between the pines, small animals moving through the undergrowth, perhaps a fox calling somewhere beyond the glen.

Instead, the silence deepened.

I heated water for a dried meal and strained to hear anything beyond the crackle of the fire. There was no wind in the branches, no insects, no movement at all. The stillness pressed against my ears.

My watch showed 21:43. Darkness filled the gaps between the trees, held back only by the small circle of firelight. I kept the rifle beside me whilst I ate and repeatedly searched the shadows.

Afterwards, I took out my notebook and recorded everything I had observed: the dimensions and position of the hole, the absence of animal tracks, the black soil, the old blasting cache and the unnatural silence. I added another sketch of the clearing, then put more wood on the fire and prepared for another night without proper sleep.

At 23:37, I decided to remain awake until midnight before trying to rest. The minutes crawled past. 23:45. 23:53. 23:58.

At exactly 00:00, the silence broke.

"Daniel."

The sound was so faint that I thought I had imagined it. I sat upright and reached for the rifle.

"Daniel, help me."

It came from the clearing. From the hole.

The voice was weak, but unmistakable.

Owen's voice.

Panic and hope struck me together. I seized my torch and moved quickly towards the clearing, forcing myself to slow before I reached the hole. I remembered what it had done to the cord.

"Owen," I called, staying several metres from the edge. "Is that you?"

There was a long pause. When the answer came, I had to lean forward to hear it.

"Yes. I'm trapped. So weak. Please help."

I aimed the torch into the opening. Its beam penetrated less than a metre before the darkness swallowed it completely.

"How deep are you? Are you hurt?"

"Don't know how deep. Been here so long. Losing track of time."

It sounded like Owen, but thinner and strained. I tried to think through the shock.

"I've got sixty metres of climbing rope. Would that reach you?"

"Maybe. Not sure. Everything's different down here. Distances don't work properly."

I moved farther from the edge. I had the rope, locking karabiners and a climbing harness, but the hole had cut the first cord as cleanly as wire through cheese. There was no reason to believe it would treat the climbing rope differently.

"Owen, tell me what happened. How did you end up down there?"

Another pause.

"Found reports. Service archives. People disappearing. Came to investigate. Fell in. Or was pulled in. Hard to remember now."

"What do you mean, pulled in? Is there something down there with you?"

The voice became louder and more urgent.

"Not now, but they come back. Dawn brings them. I don't have much time, Daniel. They'll be back at dawn. You need to get me out tonight."

I ran a hand through my hair, trying to absorb what I was hearing. Who were they? Why would they return only at dawn? None of it made sense.

Owen had been missing since Tuesday, 12 August 2025. He was a Royal Marines specialist with extensive survival training and experience in a sensitive unit whose work he could never discuss. How could he have survived seven months in a hole in the ground?

"I want to help you, but I need to understand what I'm dealing with. What's down there? What happens at dawn?"

"Please. I'll explain when I'm out. It's too dangerous to talk now. They might hear. Just please, Daniel. I can't last much longer."

I circled the hole at a safe distance. Every instinct urged me to act, to do anything necessary to save my brother. Yet something was wrong.

The timing was too exact. The voice had begun at midnight. Its warning about dawn created urgency without offering any useful information. It kept saying they but would not explain who they were.

"Can you see anything from where you are? Any light or another opening?"

"Dark. So dark. Sometimes I see lights, but they aren't real lights."

"How did you send the email if you're trapped down there?"

There was another long pause.

"Found a way. Temporary connection. Can't explain now. Please, Daniel. The rope. I need the rope."

I returned to camp with my thoughts racing. The voice was Owen's, but the situation was wrong in every possible way. The hole obeyed no physical rules I understood. The woodland around it was empty and silent. Now something in that impossible darkness was making urgent demands whilst refusing to explain itself.

I inspected the climbing rope. It was a sixty-metre rope designed and certified for forces measured in kilonewtons, more than sufficient for an ordinary rescue when used with proper anchors and equipment. But there was nothing ordinary about the hole. It had consumed the first cord without resistance. It might do the same to this rope, or to me if I went near enough.

"Daniel, where did you go?" the voice called. "Please hurry."

I carried the coiled rope back to the clearing but stopped short of the edge.

"I'm here, Owen. I'm working out the safest way to help you."

"There's no time for safe. They'll be back soon. Just lower the rope."

I hesitated. The Owen I knew was methodical, particularly in a survival situation. He would never rush a rescue if doing so placed someone else in danger.

"Let me secure it properly first," I said, buying time.

"Fine. Just hurry."

I went to the lightning-split pine and tested the trunk. Despite the damage high above, the ancient tree was solid enough to serve as an anchor. I built a secure attachment and checked it twice.

As I worked, I listened to the voice. It sounded exactly like my brother, yet the choices behind the words did not feel like him. Owen would have understood the precautions. He would have given me concise, practical information. Above all, he would have considered my safety as well as his own.

"What's taking so long? Dawn isn't far off."

My watch showed 00:37. Dawn was still hours away.

I completed the anchor and carried the free end towards the hole.

"I need to know more before I lower this. What is down there with you? Who comes at dawn?"

The voice paused. When it answered, panic edged every word.

"There's no time to explain. You wouldn't understand. Lower the rope now or it'll be too late."

I held my ground.

"Owen would want me to be careful. He'd want me to know what I was getting into."

The voice grew louder.

"I'm dying down here, Daniel. After everything I've done for you, you're going to stand there asking questions whilst I die?"

That did not sound like my brother. Owen had never used guilt as a weapon.

"A few more questions. Then I'll lower it. How deep are you? Can you see the opening?"

"I told you, distances don't work properly. Just lower the bloody rope."

The weakness had vanished. The voice was angry now.

I stepped back, keeping hold of the rope.

"One last question. When we were young, what did you carve for me the summer before I became a ranger?"

There was a shorter pause.

"A pine marten. You still have it, don't you? Now lower the rope."

It was the right answer. I reached into my jacket pocket and closed my fingers around the small wooden pine marten. Its familiar shape steadied me.

"I'm lowering it now. I'll put loops in it to help you climb."

"Just drop it straight down. I'll find it."

I fed the rope towards the opening whilst keeping well back from the rim. Its end disappeared soundlessly into the blackness. I paid out ten metres, then twenty.

"Can you see it? Can you reach it?"

"Lower. It needs to be lower."

I continued, watching for any sign of damage where the rope crossed into the dark. Thirty metres. Forty. Fifty. Almost the entire length.

"Have you reached it?"

"Almost. A little more."

I fed out the remaining metres, retaining only enough to control it. The rope went taut as something took hold below.

"I've got it," the voice said, suddenly stronger. "Now pull me up."

I braced myself and leaned back, ready to assist whoever or whatever was on the other end. The load increased. The rope tightened against the anchor.

Then I realised it was not moving as it should if someone were climbing. There were no shifts, pauses or upward rhythm. The tension simply mounted, as though something below were hauling the rope down.

The voice still came from the same impossible depth. It was not getting closer.

"Keep pulling. I'm coming."

Fear hit me with absolute clarity. I released the rope and jumped back.

The remaining slack whipped into the hole with violent force. The rope screamed across the ground. The anchor tightened around the pine, then failed with a crack that echoed through the clearing. The entire sixty metres vanished into the darkness within seconds.

Then there was nothing.

Complete silence.

I retreated with the rifle aimed at the hole, though I doubted it would help against whatever lived below. No human being could have exerted that force. Whatever had taken the rope was not Owen.

Back at camp, I tried to think. The voice had been perfect. It knew about the pine-marten carving. But my brother would never have rushed me into a dangerous rescue, used guilt to force my hand or refused to give the practical information I needed.

My watch showed 01:15. Dawn was still hours away.

I built up the fire, but its warmth did little against the cold seeping from the clearing. The stars looked small and remote above the pines. Sleep was impossible. I wrote down everything that had happened: the voice, the demands, the force on the rope and its disappearance into the hole.

An hour later, I looked towards the clearing. The perfect black circle was still there.

I needed to test it.

Taking the rifle, I returned to the trees at the edge of the clearing and kept well away from the opening.

"I know you're not my brother."

My words hung in the air.

Then Owen's voice answered, as exact as before but somehow hollow.

"What are you talking about, Daniel? Of course it's me. I've been trapped down here for months. Please help me."

"No. My brother would never rush a dangerous rescue. He'd never try to make me feel guilty for being cautious."

The voice paused, then softened.

"I'm sorry, Daniel. I'm not thinking clearly. I've been down here so long. Please. I need your help."

I took a slow breath.

"Do you remember our trip to the Lake District?"

"Of course," it replied without hesitation. "How could I forget?"

Owen and I had never visited the Lake District together.

"There was no trip," I said, tightening my grip on the rifle. "You're not my brother."

The silence lasted longer this time.

When the voice returned, it still sounded like Owen, but something beneath it had changed.

"Why are you waiting? I need help now."

I did not answer.

The air grew colder. My breath clouded in front of my face although the night had been mild. Frost spread across the moss around the hole, confined to the clearing as though an invisible boundary held it there.

"Please, Daniel," the voice said, weak and pleading again. "I'm dying. I don't have much time."

I remained silent, my finger resting against the rifle's trigger guard.

"After everything I did for you," it snarled, abandoning the pretence of weakness. "You're just going to leave me."

Its anger was raw and vicious. Nothing like Owen.

For hours it shifted between pleading, fury and cold reason. Every version betrayed itself. It used expressions my brother never used. It referred to events that had not happened. It failed questions Owen would have answered at once. Yet it knew the pine marten, something Owen had known and remembered.

I stayed until the eastern sky began to pale. As dawn approached, the voice became frantic and its performances less convincing.

"Daniel, help me now. There's no more time."

For the first time, its desperation sounded genuine.

I held my ground.

The first sunlight reached the clearing. The voice stopped in the middle of a word. The localised cold withdrew, and the frost melted rapidly from the moss.

The hole remained, perfectly dark even in the strengthening daylight, but the silence around it had changed. It was no longer the oppressive stillness of the night. Birds called among the birches. Somewhere beyond the clearing, a red squirrel scolded from a branch.

I approached carefully, stopping several metres from the edge. Sunlight could not penetrate the hole any more than torchlight had. I walked around it once and saw no visible alteration.

Back at camp, I heated water and made coffee with the small cafetiere from my rucksack. I was exhausted but too alert to rest. I recorded the night's events, including the voice's failed Lake District test, the sudden cold and the way it had fallen silent at dawn.

None of it belonged to the world I understood, but it was real. The hole was real. The voice was real. Both were somehow connected to Owen's disappearance.

Going into the opening was plainly what the thing wanted. I would not oblige it.

That day, my second full day of observation at the site, I widened the search again. I examined the surrounding pinewood, the abandoned estate track and the feeder burns. I found no footprints, discarded equipment or signs that Owen or anyone else had camped nearby.

By afternoon I had exhausted every reasonable search. The hole had not changed. It remained a circle of darkness that did not belong in the forest.

As the sun began to sink, I decided to stay for one final night. The thing had become active after midnight and fallen silent at dawn. If I was to learn anything more about Owen, I needed to watch it again.

I strengthened my camp, gathered more firewood and checked the rifle. I placed battery lanterns at measured points between the camp and clearing so that I could detect changes in visibility or frost. I also returned to the collapsed forestry store.

The thought of opening the cache sickened me. The gelignite was old, sweating slightly beneath its waxed wrapping and potentially unstable. Taking it was illegal, environmentally reckless and personally suicidal. I understood all of that. I also remembered the rope vanishing into the hole and the frost spreading across the clearing.

Using gloves and moving with excruciating care, I removed several cartridges and an old but intact fuse assembly. I carried them separately in a rigid sample case, padded so they could not knock together. They were not a plan. They were a desperate last resort.

When darkness settled, I sat beside the fire with my notebook open and the clearing in view. The black circle waited beneath the split pine as the stars appeared.

At some point my eyes closed.

Laughter woke me instantly.

I knew that chuckle. It belonged to Owen.

Then it lengthened and twisted until it no longer sounded human.

I came upright in the hammock with the rifle already in my hands. Fifty metres away, the hole looked blacker than the night surrounding it. The laughter grew louder, striking the trees and returning from every direction.

"You're pathetic, Daniel," the voice called.

It still contained traces of Owen, wrapped around something ancient and wrong.

"Your brother is dead. He died screaming."

I stepped from the hammock and checked the rifle by touch. Ten years as a ranger had taught me to remain calm during emergencies, but this was not an injured walker, a wildfire or a wounded animal. I had no training for it.

"Soon I'll wear your skin as well," the voice said.

I moved towards the clearing, keeping pine trunks between myself and the hole. Whatever lived below had proved its strength. I needed distance, cover and answers.

At the clearing's edge, I braced the rifle against a tree and aimed towards the centre of the opening.

"What are you?"

The thing laughed harder. The sound broke into wet clicks that no human throat could have made.

"We were here before your kind walked upright," it said at last. "Your brother knew too much."

It paused.

"Just like your parents."

My parents.

Their car had left a Highland pass after what the official investigation called a steering failure. I had been nineteen. Owen had been twenty-three.

"What do you know about Mum and Dad?" I demanded.

The voice changed without any transition.

"Danny, sweetheart, be careful."

My mother's voice was perfect. It had the same warmth, the same slight lift at the end of a sentence.

"You shouldn't be out there alone."

I stepped back, my throat tightening. It was not merely the words. It was every tiny inflection I remembered.

"Son, put down the rifle."

My father's deep, measured voice came next.

"That's not how I taught you to handle a firearm."

The voices cycled through my family: Mum, Dad, Owen, then all three at once, an impossible chorus speaking in unison.

"We've been waiting for you, Daniel. The last Mercer. Come closer. Join us."

I retreated towards the rucksack hanging from a nearby branch. Without taking my eyes from the hole, I reached into the rigid side compartment.

The ground around the opening cracked. Thin fractures spread through soil and moss like a web. Tar-dark strands pushed from them, climbing against gravity. They writhed nearly a metre above the ground before sinking back into the earth.

The thing was moving beyond the hole.

The voices continued, their words becoming less coherent and more insistent. My fingers closed around the padded case containing the old forestry gelignite. I removed it and the fuse assembly with deliberate care.

I knew precisely how dangerous it was. An unauthorised explosion in a national park could kill me, ignite the pinewood, contaminate the burns and end my career even if I survived. The cartridges might detonate whilst I handled them. But the alternative was allowing whatever had taken Owen to spread through Blackwood Forest.

"I can be him for you," Owen's voice said, suddenly alone. "I can be your brother better than he was. I know what you need."

"You're not my brother."

I struck a waterproof match.

The tiny flame illuminated my hands. Every voice stopped. I felt the attention of the thing settle upon me.

"You cannot stop this," it said, abandoning every human disguise. Its voice ground like stone under immense pressure. "We are eternal. We are patient. Your family has delayed the inevitable for generations, but it changes nothing."

I touched the flame to the fuse. It caught, sparks crawling towards the cartridges.

"Let's test that."

I threw the bundle into the centre of the hole. The burning fuse traced a brief arc through the darkness, then vanished without a sound.

For three seconds, nothing happened.

I dived behind the broadest pine trunk within reach and covered my head.

The detonation came as a rolling wall of force. The ground convulsed beneath me. Trees swayed, branches split and stones hammered through the clearing. Beneath the blast I heard something screaming, a sound too vast and broken to be human, like metal tearing under the earth.

Debris rained through the forest. Soil, granite fragments and shattered branches struck the ground around me. When the fall finally eased, I raised my head.

The clearing had collapsed. In place of the perfect hole was a crater roughly five metres across, choked with broken timber and disturbed earth. Dust hung in the moonlight pouring through a new gap in the canopy.

I stayed behind the tree and watched. The forest was completely silent. There were no birds, insects or wind.

This silence felt different. It was not expectant. It was the stunned quiet following catastrophe.

After ten minutes, I approached the crater. The perfect circle was gone, replaced by jagged soil and shattered roots. When I directed my torch downwards, ordinary shadow gave way to visible rock and earth. Light was no longer being swallowed.

I circled twice, remaining back from the unstable edge. Nothing moved. Nothing spoke.

Yet I still felt watched, not from the crater but from the forest around it. The sensation crawled over the back of my neck as if the trees themselves had eyes.

I returned to camp and packed without care for neatness. I forced equipment into the rucksack, secured the rifle and took out my compass, OS map and handheld GPS receiver.

The rational part of my mind said I should remain, document the damage, photograph the crater and collect further samples. Every other instinct told me to leave Blackwood Forest immediately.

I started east with the compass in one hand and my head torch cutting across the ground. I had travelled through the Cairngorms at night before, but never at that speed. I half ran where the terrain allowed, climbed over fallen pines and crossed feeder burns without stopping.

My boots slipped on wet roots and granite. My lungs burned. Every few minutes I looked behind me, although I knew that if something followed, I might never see it.

Hours passed. The forest remained unnaturally quiet. No owl called. Nothing moved in the undergrowth. There was only my breathing and the strike of my boots.

By the time grey light appeared in the east, I was several kilometres from the clearing. My legs ached from the pace, but I continued as dawn changed the forest from black to grey and then to green.

At sunrise I reached a ridge I recognised. From there I could see the glen leading towards the Upper Feshie ranger post. It was still kilometres away, but it was real and familiar.

I stopped only long enough to drink from my water bottle, then descended, letting the slope carry me towards safety.

The sun was fully up when I reached the post. I stumbled the final hundred metres, fumbled with the keys and almost fell through the door. After locking it behind me, I checked every window before collapsing into the chair at the desk.

The ordinary contents of the room should have reassured me: Ordnance Survey maps on the walls, radio equipment, the kettle and cafetiere beside the sink. Instead, they seemed remote, as though I were viewing them through somebody else's eyes.

I sat in the daylight and tried to understand what had happened. The hole. The voices. The collapse.

None of it fitted the world I knew or the natural systems I had spent my career protecting. Yet it had happened, and somewhere inside that impossible horror lay the truth about Owen.

I told nobody what I had seen. There was no sensible incident form for a hole that stole voices and memories. The ranger-service log showed only that I had taken personal leave to pursue information connected with my brother's disappearance, found nothing conclusive and returned to the post.

But I had not truly returned to duty. My body went through the motions of checking paths, helping walkers and completing reports, whilst my mind remained in that clearing.

For three days I felt unreal inside my own life. I barely ate. Sleep came in short, broken spells that left me more exhausted. Whenever I closed my eyes, I heard my family's voices woven into that hideous chorus.

I gathered every historical record available at the post and requested boxes from the ranger-service archive. During quiet night hours, I read estate papers and incident reports reaching back into the nineteenth century. Much of the material had never been digitised. It remained in cardboard boxes in the rear store, sorted by estate, glen and decade.

The oldest accounts included Gaelic place-name notes and fragments of local oral tradition warning shepherds and stalkers away from a tract of woodland where the ground was said to speak in the voices of the dead. Later estate factors had dismissed such stories as superstition.

I found an 1887 report from Coire Cailleach.

"Missing stalker, last seen near the upper birchwood," I murmured, reading aloud to stay awake. "Search parties reported hearing the missing man's voice calling from several directions at once."

A 1912 timber-survey report described a crew abandoning its work after hearing the voices of dead relatives coming from beneath the forest floor. The estate had subsequently labelled the area unstable because of supposed sinkholes.

Among the 1920s files I found references to an expedition led by Edward Mercer, my great-grandfather. The surviving correspondence mentioned geological anomalies, missing men and three field journals that had been submitted to an estate office but could no longer be located. A later index card stated that the Mercer material had been removed following consultation with unnamed officials. There was no record of where it had gone.

The discovery left me staring at our surname until the letters lost their meaning.

A 1943 estate record contained a report from Warden Alastair Reid. Walkers and estate workers had begun avoiding the north-eastern section of Glen Dubh, claiming that the forest spoke with dead voices. Reid's request to close the approach was denied for lack of substantiating evidence.

Each time I found a location, I marked it on an Ordnance Survey map. A pattern emerged: a rough circle nearly twenty kilometres across, with the hole at OS grid reference NN 812 946 close to its centre.

People had been disappearing there for generations. Reports had been misfiled, dismissed or explained away. Edward Mercer's journals had vanished. Somehow, the pattern had never been formally acknowledged.

On the morning after my third disturbed night of research, I rang Callum Fraser in the regional duty-control room.

"Callum, it's Daniel. I need a favour."

"You sound dreadful," he said bluntly.

"Thanks. Listen, can you pull the records of every disappearance in the Cairngorms National Park over the past hundred years? I need locations, dates, anything you can find, especially anything connected with Blackwood Forest, Glen Dubh or Coire Cailleach."

"That's a mountain of paperwork. What are you looking for?"

I hesitated. Owen's warning had told me to come alone and trust no one, yet here I was asking the ranger-service duty controller to search official systems. I had not fully accepted the danger then. I still wanted facts that belonged to the ordinary world.

"I'm following a hunch about Owen. It might be nothing."

Callum Fraser was silent for a moment.

"Daniel, everyone's worried about you. Fiona says you've barely spoken three words since you came back. Maybe it's time you-"

"I'm fine," I cut in. "Just tired. Will you help me or not?"

Another pause.

"I'll see what I can do. It may take a couple of days to pull everything together."

"Thanks, Callum."

For the rest of that day I worked on automatic, inspecting paths and footbridges damaged by the recent storms. It was the first of three disturbed days after the explosion. I spent the daylight hours carrying out only the duties I could not avoid, then returned to the ranger-service offices and searched old files until my eyes ached.

The estate records confirmed that Edward Mercer, our great-grandfather, had joined an expedition into Glen Dubh during the 1920s. Most of the party had vanished. The surviving account blamed a landslip, but the original journals were missing, and later references to the expedition had been removed from more than one catalogue. A 1943 report by Warden Alastair Reid mentioned lights beneath the pines and voices heard near Coire Cailleach. Someone had crossed out whole paragraphs in thick black ink.

British Geological Survey records showed no cave system beneath the relevant part of Blackwood Forest. Ordnance Survey maps showed no hollow, shaft or sinkhole at OS grid reference NN 812 946. Old Gaelic estate accounts warned shepherds away from the glen, describing it as a place where the dead called from beneath the roots. Later administrative notes dismissed those accounts as superstition.

By the third day, the pattern of suppression was almost as frightening as the hole itself. Reports had been misfiled, maps replaced and names removed from indexes. I could not tell whether that proved a conspiracy or merely reflected a century of careless record-keeping, but Edward Mercer's expedition kept appearing at the centre of it.

When I returned to my tied cottage on the evening of that third day, the sun was already sinking behind the pines. I reheated the remains of a beef casserole and ate standing at the kitchen worktop, barely tasting it. The deer rifle I used for authorised deer management was locked in its secure cabinet in the bedroom, exactly where regulations required it to be.

The knock came while I was washing my bowl.

Three sharp blows against the front door. Precise and deliberate.

I froze with water running over my hands. Nobody visited the cottage that late. The other rangers knew I valued my privacy, and walkers had no reason to be this far along a forestry track after dark.

I shut off the tap and dried my hands on my trousers. The rifle was secured too far away to reach without abandoning the door. Instead, I took the stalking knife from its sheath on the kitchen worktop.

The knock came again.

Three sharp blows. The same rhythm.

I moved into the hall with the knife held low against my leg. Through the narrow window beside the door, I could see someone standing on the step. He was tall, unmistakably a man, but his face was hidden in shadow.

"Who is it?" I called, my free hand moving towards the door handle.

"Daniel?"

The voice was weak and rough with exhaustion, but I recognised it instantly.

"It's me."

I pulled the door open.

Owen stood swaying on the step, barely able to remain upright. His clothes were torn and hung loose from a body reduced almost to bone. His cheeks had sunk beneath the skin, and his face looked stretched and sharp. His eyes seemed empty at first, but when they found mine, something in them changed. He knew me.

"Owen," I whispered.

The knife struck the floor as I reached for him.

He stumbled forwards, and I caught him when his legs gave way. He weighed almost nothing. Through the rags of his clothing I could feel every rib as I dragged him inside and kicked the door shut behind us.

"You're alive," I said, my voice breaking. "How?"

"Water," he rasped. His cracked lips could barely shape the word.

I helped him on to the sofa and hurried to the kitchen. When I returned with a glass, his hands shook too badly to hold it, so I supported his head and let him take small sips. After a while, he managed to grip the glass himself.

I examined him as he drank. He was plainly starving, but there were other injuries. Circular bruises marked his arms and neck, some fresh and purple, others fading to yellow. A jagged scar ran from his right temple to his jaw. It was red and swollen, as though it had never been cleaned or treated.

"Owen, what happened to you? How did you escape?"

"You found the hole. I heard."

He raised a trembling hand, stopping the rest of my questions.

"Food," he whispered. "Please."

I brought him what remained of the casserole, still warm in the pan. He ate mechanically, without pleasure or haste, like someone who had forgotten the sensation of hunger but remembered that food was necessary. I sat opposite him with my hands clasped between my knees to keep them from shaking.

My brother was alive. He had missed his check-in on Tuesday, 12 August 2025, and for seven months I had searched, grieved and questioned my sanity. Now he was in my cottage, solid enough to touch.

When he finished, Owen set the bowl aside and looked at me. His eyes were clearer already, more focused than they had been when I opened the door.

"You found it," he said.

It was not a question.

I nodded. "Three days ago. I heard voices. Your voice. Mum and Dad as well. I almost..."

I swallowed.

"I almost went in."

"But you didn't."

"No. I used gelignite. There was an old sealed forestry blasting cache marked on a derelict estate map. I took several cartridges and collapsed the opening."

A faint smile crossed his face.

"Smart. That's what saved me."

Owen slumped against the back of the sofa, looking utterly spent.

"I was investigating rumours," he began. His voice was still rough, but it was becoming stronger with every minute. "Service takes you to remote places. Places where local people tell stories about parts of the wilderness they won't enter. Places where people disappear."

He took another drink.

"I began noticing patterns. Different continents, different cultures, but the same stories. Voices calling your name. Holes appearing where no hole should exist. People vanishing without leaving a trail."

"Why didn't you tell me before?"

Owen met my eyes.

"I tried, during that three-week leave three years ago. I was testing the waters, trying to learn whether you'd noticed anything strange in your part of the Cairngorms."

I remembered the conversation beside the loch, when he had asked about unmapped places and areas animals seemed to avoid. I had dismissed it as exhaustion, perhaps the effects of whatever he had endured during his Royal Marines service and the sensitive specialist work that followed.

"When I disappeared," he continued, "I was following a lead from the 1920s. A research party went into this part of the Highlands and vanished. All except one man, who was found wandering alone and claiming the others had been taken below."

I thought of the records I had spent three days reading.

"I found similar accounts going back to the nineteenth century," I said. "They're scattered through estate papers, ranger files and local oral histories. No one ever joined them together. Edward Mercer's expedition journals are missing. Later records have been altered."

Owen nodded.

"That's deliberate. There are people and organisations that know about these things. They keep them hidden."

He coughed, a dry, rattling sound.

"I got too close. I found the hole, and it took me."

I leant towards him.

"What is it, Owen? What's down there?"

"An entity. Ancient. It's been there for thousands of years, feeding on people. Not only their bodies. Their memories, their emotions, the connections between them."

His voice fell to a whisper.

"It wants to understand us. It wants to perfect its mimicry."

I felt sick as I remembered the voice from the darkness. It had sounded exactly like my brother. It had known about the little wooden pine marten Owen had carved for me, because Owen himself had known. Yet when I had tested it with a fabricated memory of a family trip to the Lake District, a journey Owen and I had never made together, it had answered wrongly.

"The hole opens into a cave system," Owen continued. "Kilometres of tunnels. It kept me alive in a chamber with others."

"Others? There were more people down there?"

He looked away. His eyes lost focus.

"There were. They didn't last as long as I did. It fed more slowly on some than on others. I don't know why it kept me alive."

I thought of the tar-dark strands I had seen climbing against gravity through the cracks around the hole.

"How did you escape?"

"When you triggered the blast, the entity was disrupted. Feeding on several people at once takes concentration. The explosion broke that concentration. The tunnels shifted, and part of one wall collapsed. It exposed a passage I hadn't seen before."

His hands trembled as he put down the glass.

"I ran for what felt like days. Eventually the passage reached a small opening several kilometres from where I went in. I've been trying to reach you ever since."

I struggled to absorb what he was telling me. It was impossible, but the impossible had spoken to me beneath an ancient lightning-split Scots pine. It had swallowed light and sound, severed my cord and tried to drag sixty metres of climbing rope out of my hands. I had watched fog recoil from it.

"Owen," I said carefully, "when you were down there, did it tell you anything about Mum and Dad?"

His eyes snapped towards mine, suddenly alert.

"It knew them, Daniel. It's been hunting our family for generations."

"What?"

"The crash wasn't an accident."

His voice dropped to a whisper.

"Mum and Dad discovered something about our family's connection to these entities. They tried to protect us by moving away, but it found them."

I stood and paced across the room, dragging both hands through my hair.

"That isn't possible. The police report blamed a steering failure. Their car left a Highland pass."

"Think about it," Owen said. "Dad knew that road. It was dry, there was no other vehicle involved, and there were no witnesses. They were targeted, Daniel."

I remembered the official explanation. An unexpected steering failure, a familiar stretch of pass road, a sudden plunge through the barrier. I had never been satisfied by it, but I had been nineteen and paralysed by grief. Owen, at twenty-three, had arranged compassionate leave followed by a temporary shore posting so he could spend the next several months near me. Neither of us had possessed the strength to question the report.

"How does it feed?" I asked, though I was no longer sure I wanted the answer.

Owen touched the circular bruises on his arms and neck.

"It attaches feelers here. It pulls your memories out. Recent memories come first because they're easier. Then it goes deeper. Childhood. The people you love. Everything that binds you to anyone else. It uses what it learns to build better traps."

He drew an unsteady breath.

"That's why it could sound like Mum and Dad. It took those memories from me. It learnt their voices, their phrases, all the little things only family would know."

I lowered myself into the chair, trying to comprehend the horror of it.

"We need to report this," I said. "We need help from the ranger service, Police Scotland, perhaps your former unit."

"No."

The word came sharp and immediate. For the first time since he arrived, Owen sounded frightened rather than exhausted.

"No authorities. They're compromised."

"What are you talking about?"

"The entity isn't alone. There are others like it in remote places across the world. There are people who protect them, including people in positions of power."

I stared at him. The Owen I remembered was practical and restrained, a Royal Marines specialist who spoke only when he had something worth saying. The man before me was talking about ancient creatures and an international conspiracy.

He saw the doubt in my face.

"Why do you think no one connected the disappearances? Why are records removed and maps altered? These things have been feeding on human beings for centuries. They have human allies who keep their existence secret."

"Why would anyone help them?"

"Power. Knowledge. Protection, perhaps."

He coughed again, his entire body shaking with the effort.

"I don't know everything. I only know we cannot trust the authorities."

His warning made me think of my call to Callum. I had asked a duty controller to search restricted records using Owen's name and details before I truly understood what "Trust no one" might mean. The email account had received messages during Owen's disappearance, but the technical review had found no authenticated access until the routed outgoing message dated 15 March 2026, 21:46. Receiving mail had never proved that Owen was reading it. Now I wondered who else might have noticed my enquiry.

I fetched a blanket from the bedroom. Owen was shivering although the cottage was warm.

"You need a doctor," I said as I draped it over his shoulders.

"Not yet. Not until I know who we can trust."

He gripped my arm with startling strength. It was far too much strength for someone who had scarcely been able to stand half an hour earlier.

"Promise me you won't tell anyone I'm here. Not Fiona Grant, not Callum, not the other rangers. No one."

I hesitated, then nodded.

"All right. For now. But you need rest, and tomorrow we'll decide what to do."

Owen relaxed and sank deeper into the sofa.

"Thank you for believing me. I wasn't sure you would."

"After what I saw at that hole, I'd believe almost anything. Get some sleep. We'll talk in the morning."

I helped him lie down and brought another blanket. Within minutes his breathing had settled, although his face remained tense in sleep.

I went to the window and looked out at the darkness surrounding the cottage. Somewhere beyond the glass was the thing that had taken my brother and might have killed my parents. The collapse had not destroyed it. It was still beneath Blackwood Forest, injured or disturbed, but waiting.

According to Owen, it was not alone.

I spent the night listening as his broken account emerged in fragments. His sleep was restless, punctuated by violent jerks and words I could not understand. Whenever he woke, he resumed talking as if he had never stopped.

"They were here before us," he said during one of his clearer periods at about 03:00. His voice had grown stronger, but his eyes kept moving towards the windows. "They inhabit remote places all over the world. Deep forests, mountain ranges, caves, deserts. Anywhere people rarely go."

"How many are there?" I asked quietly, as if something outside might hear.

"Dozens. Perhaps hundreds."

His fingers traced one of the round bruises on his neck.

"They feed on us, but not as an animal feeds on prey. They consume experience, memory and the connections between people."

He described how they lured victims with the voices of loved ones, harvested from those they had already taken.

"That's why it knew Mum and Dad so well," I said. My stomach turned at the thought.

Owen nodded.

"They're extraordinary mimics. Not only voices. Mannerisms, familiar phrases, private jokes, things only a family member would know. The longer they feed on someone, the more they can use."

"But they can only use what the victim genuinely knew," I said. "At the hole, I invented a memory about us visiting the Lake District. It accepted the story, then gave the wrong answer. We've never been there together."

"Then you found the limit," he said. "It can steal a memory. It cannot create the truth behind one."

He coughed, a dry rattle deep in his chest.

"Those other people you mentioned," I said. "The ones held with you."

"Gone now."

He stared at his hands.

"The entity consumed them completely. I think it kept me alive because of our family's connection."

Near dawn, as the first grey light entered the cottage, Owen told me the worst part.

"Our family has a particular connection to these things," he said, sitting straighter despite his supposed exhaustion. "Our great-grandfather, Edward Mercer, was part of the expedition in the 1920s. The one I told you about."

I leant forwards.

"The expedition in which everyone disappeared except one man."

"Edward was the survivor. The official account said the others died in a landslip. The truth is that he found one of these creatures and made some kind of pact with it."

I went still.

"What kind of pact?"

"I don't know all the details."

Owen rubbed his temple, following the jagged scar down towards his jaw.

"The entity showed me fragments. Memories taken from other members of our family. I think Edward offered it something in exchange for his life. Whatever bargain he made passed through the bloodline. That's why it has hunted our family."

"The journals are missing," I said. "Every archive reference leads to an empty space."

"He hid them. Or someone removed them after his death. I think the pact is unravelling, or perhaps Edward never meant to honour it. He spent the rest of his life researching these entities and looking for a way to fight them."

Owen continued as dawn spread through the trees. The story came in disconnected pieces: Edward's concealed journals, a loose network of researchers who had learnt part of the truth, public bodies that had buried evidence, and people whose protection of the entities might have lasted for generations. He offered no firm explanation for what Edward had promised or why anyone would preserve the arrangement.

The more he spoke, the less his physical condition made sense. Hours earlier he had been unable to hold a glass. Now his voice was clear, his posture upright and his grip powerful. I told myself that food, warmth and the release of fear could restore a man quickly. I did not entirely believe it.

As sunlight touched the upper branches outside, Owen finally seemed to fall into a deeper sleep. I sat watching him while my thoughts raced through everything he had said. His story was impossible, yet I had seen enough to know that some part of it was real.

At 06:30, I checked my watch. I needed to ring Fiona and tell her I would not be coming in. I could not leave Owen alone in his condition.

My throat was dry after the long night. I rose quietly and went to the kitchen for water. The tap made its usual knocking sound as trapped air moved through the pipes. I filled two glasses and carried them back towards the sitting room.

Owen was gone.

The blankets lay in a heap on the sofa.

I put down the glasses and checked the bathroom, then the bedroom. Nothing.

"Owen?"

The silence made my skin crawl.

The front door was still locked from the inside. I unlocked it and stepped on to the front step, searching the forestry track, the rear garden and the trees beyond the cottage.

The morning was quiet apart from birdsong somewhere deeper in the pinewood.

"Owen!" I shouted.

My voice struck the trees and faded.

I went back inside, panic rising in my chest. He had been too weak to walk unaided when he arrived. Even if his recovery had been genuine, he could not have left through a locked door without my hearing him.

Then I saw something on the low table that had not been there before.

A folded sheet of paper.

I opened it. The message was written in Owen's neat handwriting.

You need to leave now.

The explosion did not kill it. Nothing can. It is recovering, and it will come for you.

Our parents discovered the truth and tried to protect us by moving away, but it found them.

Trust nothing in Blackwood Forest. Your memories have been manipulated. We were brought here as part of a larger plan.

I have gone to find answers and end this.

Do not follow me. One of us needs to survive.

I read the note three times, my hands shaking.

Our memories had been manipulated. Which memories? What larger plan? How had Owen gone from near starvation to speaking with perfect clarity, gripping me with trained strength and vanishing from a locked cottage?

I stood motionless until something drew my attention to the window.

There was nothing beyond it except Scots pines and morning light, but I felt watched.

The birds had stopped singing.

I did not reason through what I did next. I followed the habits Owen had drilled into me years before.

I dragged a holdall from the wardrobe and threw clothes into it. I did not fold or sort anything. I took the emergency cash from the hollowed book on my shelf, my passport and the small wooden pine marten Owen had carved for me. Everything else could remain.

As I packed, I expected another knock or a familiar voice calling from between the trees. The morning stayed utterly silent.

I stopped in front of my ranger uniform, which hung from the bedroom door. Ten years of service. A career I had loved. People I cared about and work that had given my life shape.

I would have to abandon all of it.

I left the uniform hanging there.

I placed the holdall in the Land Rover Defender and took one last look at the tied cottage. It had been my home for a decade, the first place that had truly felt like mine after Mum and Dad died.

Now it looked wrong. The windows were too dark in the daylight, the walls too still beneath the trees. If Owen was right and my memories had been altered, how much of my life there had been real?

I climbed into the Defender and started the engine. As I pulled on to the forestry track towards the A9, my mobile rang.

It was Callum.

"Daniel, where are you? You're meant to be inspecting the north sector path this morning."

I considered inventing an excuse, something ordinary and convincing. Then Owen's warning returned to me.

Trust nothing in Blackwood Forest.

"I can't explain now," I said. "I'm sorry, Callum."

"Daniel, what's going on? Are you all right?"

I ended the call and switched off the mobile.

The forestry track ran for eight kilometres before reaching the A9. Eight kilometres of trees that suddenly appeared to be watching me.

I drove faster than was sensible. The Defender jolted over ruts and potholes whilst the pines pressed close on both sides. Every bend revealed more of the same dark trunks.

Six kilometres. Five. Three.

The forest went on.

About two kilometres from the road, I glanced into the rear-view mirror and flinched.

For a moment, I thought I saw Owen standing among the trees, watching the Defender leave. He stood perfectly upright, no longer starved or weak, his face pale between the trunks.

I blinked.

There was nothing there but forest.

I pressed harder on the accelerator. The Defender gathered speed, and at last the A9 appeared ahead, empty in both directions.

I turned east, away from Blackwood Forest, away from the career I had built, and away from the brother I had found and lost again in less than twelve hours.

I did not know where I was going or what I would do when I arrived. I did not even know whether the visitor had truly been Owen, or whether the thing beneath the forest had learnt enough to pass one final test.

I knew only that one of us had to survive if there was ever to be an end to it.

For the moment, survival meant putting as much distance as possible between me and whatever waited beneath the ancient pines.
