The Voices in Grizedale Forest

I pulled my water bottle from my rucksack and took a long drink, then checked my watch. It was 15:17. We had been walking for about four hours, and the group was coping with the pace better than I had expected. After eight years of leading survival training exercises through Grizedale Forest in Cumbria, I had learnt to read people quickly. This group had a useful mix of experience, which usually created the best environment for learning.

Aiden Malik walked a few paces ahead. He crouched beside a fallen log and examined something in the mud. His tracking skills impressed me more each time we stopped. The lad had instincts that could not be taught, the sort of awareness that separated casual weekend walkers from people who genuinely understood the outdoors.

"Red-deer tracks," he called back to us. "Old ones. Perhaps three days. They're heading east towards Bogle Beck."

Owen Price immediately pulled out his phone, probably hoping to take a photograph, although I knew he would not find a mobile signal there. His university-student enthusiasm was endearing, even if I had to keep redirecting his attention from documenting everything to practising the skills we had come to learn.

Nia Morgan nodded at Aiden's assessment and adjusted the straps of her rucksack. She moved with the confidence of someone who spent a great deal of time outdoors, rather than somebody who ventured out for the occasional weekend walk. Her equipment was good quality and well maintained, and she had not complained once about the pace or the terrain. Having another experienced walker in the group always made my job easier.

Chloe Bennett stayed close to Martin Shaw. Both looked slightly breathless, but they were keeping up. Martin's office clothes were hardly suitable for a survival course, and Chloe's trainers would cause trouble if we encountered any serious slopes, but they were trying hard. Sometimes the most determined trainees learnt the most, even when they began with the least experience.

I took out my GPS receiver to check our position.

We were meant to be following the marked route towards a bivouac clearing I had used dozens of times before. It lay about three kilometres ahead, with reliable access to water and natural shelter from the wind. The route was straightforward: remain on the main path, then take the fork descending towards Bogle Beck.

The GPS screen flickered into life. I waited for it to lock on to our coordinates.

When the display settled, I stared at the figures, then checked them again. We were roughly seven hundred metres off route, heading north-west instead of north-east.

That made no sense. I had walked this route so often that I could have navigated it in darkness.

I stopped and unfolded my paper map against the trunk of a tree. According to the coordinates, we had entered a compartment of Grizedale Forest that I had never explored, despite being only a short distance from the managed routes. In eight years of bringing groups through the forest, I had always kept to paths I knew were safe and properly maintained.

"Everything all right?" Nia asked when she noticed I had stopped.

I traced our progress across the map with one finger, trying to understand where we had gone wrong. The junction at which we should have turned east was clearly marked. I remembered passing the expected stand of larches and the split boulder beside the path, yet I could not remember seeing the actual fork. Or perhaps I only thought I remembered the landmarks. Their positions now seemed subtly wrong, and the path beneath our boots curved in a direction the map did not allow.

The GPS did not lie, and neither did the contours of the ground around us. The mistake troubled me more than it should have done.

Navigation was fundamental, the basis of outdoor safety. I had drilled the same rules into hundreds of trainees over the years: always know where you are, and always have more than one means of finding your way back.

Yet there I was, leading five people who trusted my experience, having somehow strayed from a route I could supposedly have followed blindfolded.

"We need to retrace our steps," I told them. "We've drifted about seven hundred metres off route. I must have taken a wrong turn somewhere."

Aiden looked surprised. "Really? The path seemed clear."

That was the problem. It had seemed clear to me as well.

Whatever path we had followed looked legitimate, its surface worn enough that I had not questioned it. But routes through woodland could be deceptive, particularly where deer made tracks that resembled paths used by people. Even so, this one had been unusually convincing.

Owen pushed his glasses up his nose. "How do you know we're off course?"

I held up the GPS receiver. "These coordinates don't match our intended position. The bivouac is north-east of where we started, but we've been travelling north-west for the past hour."

Chloe glanced nervously at the surrounding trees, as though they might offer reassurance. "Are we lost?"

"No," I said firmly. "We're simply not where we planned to be. There is a considerable difference. I know where we are now, and I know how to return us to the proper route."

That was mostly true. The GPS gave me our position, and the map showed terrain features that should have guided us back to the main path. But the fact that I had made the error at all left me uneasy.

Mistakes outdoors had consequences. Even small ones could develop into serious problems if they were not dealt with promptly.

Martin wiped the sweat from his forehead with a handkerchief. "How much extra walking are we talking about?"

"About seven hundred metres back to wherever we went wrong, then roughly three kilometres to the bivouac. Perhaps another hour, provided we maintain this pace."

I began folding the map, but Chloe's voice stopped me.

"What's that?"

She pointed through the trees to our left, where something dark and angular interrupted the forest's natural lines.

I followed her gaze and saw the corner of a structure, mostly concealed behind conifers and tangled vegetation.

"Looks like a building," Owen said, already taking several steps towards it.

I studied the shape through the trees. It was unquestionably man-made, too regular and vertical to be natural, but there should not have been any buildings in that part of Grizedale. The Forestry England maps showed no cottages, shelters or wardens' facilities there, and I had never heard of any historical site hidden in that compartment of the forest.

Aiden moved closer for a better look. "It seems old. Perhaps a forester's cottage."

The structure stood about fifty metres away, partly obscured by trees and undergrowth. I could make out weathered timber, dark stone and a steep slate roof, the sort of construction that suggested it had stood there for many decades.

Something about it felt wrong, although I could not identify what had provoked the instinct.

"We should have a look," Nia said. "It might be interesting from a historical point of view."

Owen nodded eagerly. "There might be information about the old routes. Maps or records, perhaps."

Every survival instinct I had developed during eight years as an outdoor instructor told me to walk away. Abandoned buildings in remote places could be dangerous for any number of reasons: unstable floors, wildlife, illegal activity, or simply the principle that if something appeared where it did not belong, it deserved caution.

But the group was already moving towards it, curiosity overcoming good sense.

Owen and Nia went first, with Aiden close behind. Chloe and Martin remained near me, although they watched the others with obvious interest.

"Five minutes," I said, making a decision I suspected I would regret. "We take one quick look, then return to the route."

I moved ahead as we pushed through the undergrowth. My legal folding rescue knife was buried in my rucksack rather than hanging ready at my hip, and I was suddenly conscious of how little use it would be if we encountered a genuine threat.

The building resolved into clearer detail as we approached. It was a low stone-and-timber forester's cottage with a slate roof and a narrow veranda. The roof appeared intact, but the timber had weathered to grey and was stained by decades of Cumbrian rain.

Windows stood on either side of a heavy wooden front door, their glass too filthy to see through. There were no cables or signs of modern utilities, which was unsurprising in such an isolated location. Yet the cottage looked solid, nothing like a crude shelter assembled from salvaged materials.

"Who would build a house all the way out here?" Chloe asked quietly.

I was wondering the same thing. The location made no sense for a permanent home. It was too far from any road and too isolated from the nearest community, yet it was too substantial to have been a temporary shelter and too carefully built to suggest an illicit encampment.

Aiden walked around one side, inspecting the exterior. "No obvious damage. The walls and foundations look sound. Whoever built this knew what they were doing."

I approached the front door and saw that it stood slightly ajar. The timber was thick and heavy, fitted with old ironwork that had rusted but still appeared functional.

A small window beside the door was filmed with grime, although I could distinguish the edge of what might have been furniture inside.

The sensible choice was to turn round and leave. Abandoned buildings were unpredictable, and five people depended upon my judgement to keep them safe. But curiosity was fighting caution, and the group had already committed itself to exploring.

I pushed the door open with my boot and allowed it to swing fully back before crossing the threshold. The hinges gave a long creak, but the door moved smoothly, without catching as I had expected.

The smell struck me at once: decay mingled with something cloyingly sweet, like flowers left too long in stagnant water.

I breathed through my mouth and stepped inside, waiting for my eyes to adjust to the dimness.

The main room was larger than I had expected. A stone fireplace dominated one wall, while windows on two sides admitted a weak, filtered light through decades of dirt. The furniture was old but substantial: a broad wooden table, several chairs and a bookcase against the far wall.

Dust covered everything, but nothing appeared damaged or disturbed.

It was the painting above the fireplace that held my attention. The large canvas sat in an ornate frame and depicted a woman in a pale blue dress standing beside a dark lake. The brushwork was precise and accomplished, but the woman's face had been deliberately smeared away, as if the painter had dragged a hand through the wet paint until her features became a blank, indistinct oval.

"This is extraordinary," Nia said as she stepped beside me. "The preservation is remarkable if it's really as old as it looks."

Owen had already gone to the bookcase and was running a finger over the spines of leather-bound volumes.

"Some of these books look ancient. Properly ancient."

Near the entrance, Aiden found a small oak document chest resting on a bench. A folded piece of yellowed paper had been tucked beneath it.

"There's a note here," he said.

He carried the chest to the table, then placed the paper beside it. The handwriting was faded but legible, written in an old-fashioned hand with what appeared to be fountain-pen ink.

I picked it up and read aloud.

"When borrowed faces speak from night, Do not trust the shape or voice. Where darkness hides from naked sight, Direct light shall strip its choice."

A chill travelled down my spine. It sounded like a riddle or warning, the sort of cryptic message suggesting that whoever had lived there had feared things far stranger than isolation in the forest.

Chloe edged closer to Martin and lowered her voice. "This place feels wrong. We shouldn't be here."

I was beginning to agree. The cottage was too well preserved, too carefully arranged, as though someone had stepped outside moments ago rather than abandoned it years before. The painting repeatedly drew my eye, its erased face seeming to watch us despite possessing no visible features.

Aiden lifted the lid of the oak chest. Inside lay old photographs and bundles of documents.

Before anyone could inspect them, a sound from outside made us all freeze.

It was a screech, high-pitched and unmistakably inhuman. It did not sound quite like an animal either, but something poised between the two. Every hair rose along the back of my neck.

The noise continued for several seconds, then stopped abruptly, leaving absolute silence.

"Out," I said at once. "Everyone out, now."

The chest slipped from Aiden's hands as we rushed for the door. I pushed past Martin and Chloe and shoved the heavy door wide. Behind me, chairs scraped across the floor and somebody struck the table. All six of us moved at once, a confusion of elbows and rucksacks squeezing through the narrow doorway.

I jumped down from the veranda and spun round, counting as the others stumbled out behind me. Aiden emerged first, followed by Nia and Owen, then Martin pulling Chloe by the arm.

Five trainees. Everyone was outside.

I scanned the tree line around us. The forest looked precisely as it had when we arrived: conifers rising above thick undergrowth, patches of shadow lying beneath the branches, nothing moving and nothing calling. There was only the ordinary whisper of wind through needles and leaves and the sound of our own heavy breathing.

But the screech had come from nearby. Something was out there.

Then I heard it again.

The sound tore through the clearing, beginning low before rising to the same impossible pitch that made my teeth ache. This time it was closer. Much closer.

The first cry had seemed to come from perhaps a hundred metres away, somewhere deeper among the trees. This one sounded as if its source were directly beside us.

"Move," I said, snatching up my rucksack from beside the veranda steps. "We're leaving now."

I did not wait for questions. My training had taken over completely. Unknown threat, unknown capabilities, group safety compromised. The only sensible response was to create distance and reassess from somewhere safer.

I headed for the gap through which we had entered the clearing, moving quickly without quite breaking into a run. Running encouraged panic, and panic injured people.

Behind me, the others scrambled to collect their gear. Nia stayed close on my heels, her breathing measured and steady. She understood the urgency without requiring an explanation. Aiden and Owen followed close behind, their boots crunching over fallen twigs and conifer needles. Martin was already breathing hard, and Chloe gave a small whimper that told me she was terrified.

Good. Fear would keep them moving.

I forced a way through the undergrowth, branches catching at my sleeves as I tried to retrace our approach towards the main path. The forest felt different now, heavier and more confined, as though something watched us from every gap between the trunks. Each shadow seemed malformed. Every flicker at the edge of my vision tightened my muscles.

After eight years of guiding people outdoors, I had developed good instincts for danger. At that moment, every instinct I possessed was screaming at me.

A branch snapped somewhere behind and to our left, back towards the cottage.

Something large was moving through the woodland without attempting to conceal itself.

"Callum," Nia whispered, her voice taut.

She had heard it too.

I stopped and raised a hand, signalling for everyone to freeze.

The group crowded behind me. Their fear felt almost physical, like heat radiating from their bodies. Martin was panting. Chloe had seized his arm and held it so tightly that her knuckles had turned white.

Another branch broke, closer this time.

Whatever followed us was gaining ground. It moved through the forest faster than anything of its apparent size should have been able to move. I heard undergrowth being crushed and forced aside, as though it drove straight through every obstacle instead of passing around them.

That was not the behaviour of any ordinary animal. Red deer could be large and noisy, but they did not plough through dense woodland like machinery. A fox would have moved quietly. Even livestock loose in the forest would not have made that sound.

This was something that no longer cared whether we heard it coming.

"We need to run," I said quietly, turning to the group. "Stay together. Follow me and do not stop for anything."

Owen opened his mouth as if to ask a question, but I was already moving.

I pushed through a stand of young conifers, their branches whipping back behind me. The main path should have been about fifty metres ahead if I had judged the distance correctly. Once we reached it, we could move faster and put some genuine distance between ourselves and whatever pursued us.

The crashing grew louder and quicker. Whatever followed had abandoned all restraint and was now travelling at full speed. I heard whole saplings snap, the sharp reports of breaking timber echoing between the trees.

My blood went cold. Nothing natural moved through dense forest like that.

"Run!" I shouted over my shoulder. "Run now!"

The group broke into a sprint behind me. Their feet pounded the wet forest floor, their breathing becoming ragged as fear and exertion struck together. Martin was already losing ground. Years behind a desk had not prepared him for this demand, and his unsuitable clothes made matters worse.

I broke through the edge of the trees and reached the packed earth of the main path. Its familiar route markers and worn surface should have reassured me, but the crashing behind us continued to close the distance.

Aiden emerged next, his face flushed but his breathing controlled. Nia followed with the same efficient stride she had maintained throughout the day. Owen stumbled out after her, his camera bag bouncing against his hip.

Where were Martin and Chloe?

I spun towards the trees. They should have been directly behind Owen. Martin was slower than the others, but Chloe had kept pace perfectly well during the walk. They could not have been more than a few seconds back.

"Martin!" I called. "Chloe!"

The crashing stopped.

Complete silence descended upon the forest. There was no wind, no birdsong and no rustle of small creatures in the undergrowth. Even the woodland's usual background murmur had ceased, as though every living thing were holding its breath.

Then Chloe screamed.

The sound cut through the silence, high and terrified and filled with pain. It came from the direction of the cottage, perhaps thirty metres inside the trees, but ended abruptly, as if a hand had closed over her mouth.

"Chloe!"

Martin's voice shouted from the same direction.

"Chloe, where are you?"

I started back towards the trees, then stopped.

Martin's voice had sounded wrong. Not merely frightened, but wrong in a way I could not immediately define. The pitch was correct. The words were plausible. Yet something in it made my skin crawl. It was too measured, too cleanly delivered.

"Martin!" I shouted. "Where are you? Keep talking so I can find you."

There was no answer. Silence settled again.

Aiden had already begun moving towards the tree line, his jaw set.

"We have to go back for them."

"Wait." I caught his arm.

Something was profoundly wrong. Chloe's scream had contained genuine terror. I was certain of that. Martin's voice afterwards, however, had been too controlled for a man whose companion had just screamed and vanished.

"Help me!" a voice called from among the trees.

It was Chloe, weak and frightened.

"Please help me. I'm hurt."

Aiden pulled against my grip. "She's injured. We have to help her."

But I stared at the trees while my thoughts raced. Chloe's voice was coming from the wrong direction.

She had been behind Owen when we began running. She should have been somewhere between our position and the edge of the clearing. Instead, her voice came from deeper in the forest, back towards the cottage.

"I can't move," Chloe called again. "My leg is trapped. Please don't leave me."

It was unmistakably her voice, with the same pitch and frightened tone she had used throughout the day. Yet it came from at least fifty metres away, and she could not possibly have travelled that far sideways through the undergrowth in the few seconds since we had last seen her.

"Callum," Nia whispered beside me. Her face had lost all colour. "That isn't right."

She had reached the same conclusion. The voice was perfect, but its location was impossible.

"Please," it called again.

This time the voice was Martin's.

"Please don't leave me out here," Martin said from exactly the same place. "I'm lost. I can't find the path."

Ice seemed to flood my veins.

Martin had been behind Chloe when we began running. There was no possible way they had both reached the identical spot fifty metres off route without our hearing them force their way through the vegetation.

Aiden stared at the tree line, bewilderment giving way to fear.

"How can they both be in the same place?"

The voice came again, and this time my heart seemed to stop.

"Callum," it said in a voice I had not heard for three years. "Callum, I'm lost. I need help."

Daniel Hargreaves. My brother's voice, calling my name from the dark forest.

Daniel had been dead for three years.

I had watched his coffin lowered into the earth after the climbing accident in Eryri that took him from me. Every year on the anniversary, I had stood at his grave and spoken to a headstone because it was all I had left of him.

But his voice was calling from the trees, using the same tone he had always used when he was in trouble and needed his older brother.

"Callum, please," Daniel called. "I can't find my way back. I'm scared."

My legs threatened to give way.

It was impossible. Daniel was dead. I had seen his body after the fall. I had identified him at the mortuary. I had helped carry his coffin.

Yet that was his voice.

It was not merely similar, nor was it somebody performing an impression. It was Daniel speaking to me from a place where he could not possibly be.

"What the hell is happening?" Owen whispered. His face was white with terror.

I forced myself to think through the fear and confusion.

Daniel was dead. Whatever waited inside those trees was not my brother, but it could reproduce his voice perfectly. It had imitated Chloe, then Martin, and now Daniel. Every voice was flawless. Every one came from the same location.

The thing that had crashed through the woodland behind us, moving too quickly and making too much noise, had caught Chloe and Martin somehow. Now it was using their voices to lure us back.

And it knew Daniel's voice.

It knew about my dead brother and understood precisely how to use him against me.

"It isn't them," I said, though my voice shook. "Whatever is in there, it isn't them."

"Callum," Daniel called again, and I heard pain in his voice.

It was the exact pain I remembered from our final conversation, three days before the accident.

"Please don't leave me. I need you."

Every instinct I possessed as an older brother urged me to run towards that voice, find Daniel and help him as I had done countless times when we were children. To do what I had been unable to do when he fell from the cliff and died alone in the mountains.

But Daniel was dead, and whatever used his voice had just taken two people entrusted to me.

"We're leaving," I said, turning away from the trees. "Now. We're getting out of here."

"But Chloe and Martin..." Aiden began.

"They're gone," I said. "And if we enter those trees, we will be gone as well."

I set off along the path at a fast walk, not quite running but moving as quickly as I could without surrendering control. The others followed, their footsteps hesitant and frightened.

"Callum," Daniel's voice called once more, growing fainter as we put distance between ourselves and the trees. "Don't leave me alone again."

I kept walking, although each step felt like abandoning my brother for a second time. The voice was so real, so completely Daniel, that part of me remained convinced he was genuinely out there and needed my help.

But Daniel was dead. Whatever hunted us in Grizedale Forest was using the voices of people we loved to draw us into its trap.

I would not let it take anybody else.

The path extended ahead into the gathering darkness. Each step carried us farther from the cottage and the thing's hunting ground. My legs burned under the pace, but I could not slow down while I knew what followed us.

Martin's scream tore through the forest.

It came from perhaps two hundred metres behind us, a sound of raw terror that froze my blood. It lasted three or four seconds, long enough for my mind to construct images of what might be happening to him, then stopped exactly as Chloe's had.

It ended cleanly, as if somebody had thrown a switch.

"Martin!" Aiden shouted, wheeling round.

I seized his arm before he could take a step towards the sound.

"Don't."

"But he's..."

"He's gone."

The words tasted like ash. "The same as Chloe."

Aiden's face turned pallid in the fading light. Behind him, Nia had stopped as well. Her breathing remained controlled, but her eyes were wide. Owen stood frozen, clutching his camera bag as if it might protect him.

"We can't simply leave him," Aiden said.

But the conviction had drained from his voice. He had heard the way Martin's scream ended. We all had.

"That thing has him." I maintained my grip on Aiden's arm, feeling the tension in his muscles as he fought the urge to go back. "If we turn round now, it takes us too."

The forest became silent again. There was no wind and no birdsong, only our ragged breathing and the distant rush of water over stone.

Bogle Beck was close, perhaps eight hundred metres away. The bivouac we had intended to use stood near one of its upper stretches, but if we reached the watercourse and followed it downstream instead, it should eventually lead us to a forest road or managed path. It offered a route out of the nightmare.

First, we had to survive long enough to cover the remaining distance.

"Move," I said, urging Aiden forwards. "As fast as you can without running. Stay together."

We found a rhythm. I led, with Nia behind me, then Aiden, and Owen at the rear.

Owen's breathing grew harsher. His feet began catching on the uneven ground. The lad was moving on adrenaline and terror, and neither would sustain him for much longer.

The trees crowded the path on both sides, their branches forming a canopy that shut out the last of the daylight. I removed my head torch but did not switch it on. Its beam would help us navigate, but it would also advertise our position to anything watching from the dark.

Aiden disappeared between one step and the next.

I heard Nia draw a sharp breath behind me and felt the group's movement change.

When I turned, empty space occupied the place where Aiden had been walking. There had been no sound, no struggle and no warning. One moment he was there; the next, he was not.

"Aiden?" Owen's voice cracked on the name.

The path bore no evidence of what had happened. There were no scuffs in the earth, no broken branches and no sign that Aiden had ever walked there. It was as though the forest had swallowed him whole.

"Where did he go?" Nia whispered as she moved closer to me.

I searched both sides of the path for movement, for tracks or any indication of where Aiden might have been taken. His natural aptitude, his pride in noticing every bent stem and print in the mud, had done nothing to save him.

Whatever hunted us moved in ways that left no trace.

"Aiden!" Owen called, louder this time.

"Quiet," I hissed, catching him by the shoulder. "Do you want that thing to know exactly where we are?"

Owen's eyes looked enormous behind his glasses, reflecting the last scraps of light beneath the canopy.

"But Aiden's gone."

"I know." The words came out more harshly than I intended, but there was no time for gentleness. "We have to move now."

I switched on my head torch. Its beam cut through the darkness ahead, revealing the path descending between great conifer trunks that stood like silent sentries. Every shadow could hide something waiting to seize us. Every gap between the trees could be a trap.

We moved faster, almost jogging down the slope. Nia kept pace easily. Her experience showed in the careful placement of her boots; even in the uneven beam, she did not stumble. Owen struggled more, his breathing becoming laboured as we hurried through the darkness.

Then Aiden's voice called from somewhere among the trees to our left.

"Callum, over here. I've found something."

It was perfect: Aiden's enthusiasm, his excitement at discovering some new sign in the woods. If I had not seen him vanish, I would have believed he was truly out there, inviting us to inspect whatever he had found.

"Don't listen," I said without slowing. "Keep moving."

"But that's Aiden," Owen said, turning his head towards the sound. "He's alive."

"No, he isn't."

I took Owen's arm and pulled him along the path. "That thing has his voice now, just as it had Chloe's and Martin's."

The voice called again, closer.

"Callum, I need help. I'm hurt."

The mimicry was exact. It used the same tone Aiden had used after cutting his hand on a rock during a training exercise the previous month, the same slight breathlessness and the same restrained edge of pain.

Had I not witnessed his disappearance, I might have gone to him.

Instead, I forced us onwards, my head-torch beam bouncing with every stride. The sound of running water grew louder. Bogle Beck was near, perhaps another four hundred metres away.

Owen screamed behind us.

I spun, sweeping my head torch back along the path. Nia stood three metres away, her face pale in the beam. Beyond her, the route was empty.

Owen had gone.

"I didn't see anything," Nia said, her voice held tight under control. "He was directly behind me."

Owen's voice cut across hers from the darkness to our right.

"Help me. Please, somebody help me."

The same desperate tone. The same fear.

Owen was twenty years old, full of questions and enthusiasm about outdoor survival. Now his voice was merely another instrument for the thing hunting us.

"We're the last two," Nia said quietly.

I nodded, unable to trust my voice.

Five people had been entrusted to me. Four had already been taken, one after another.

Daniel's voice had been psychological warfare, an attack upon my guilt and grief. But these trainees were real people who had trusted me to protect them in a forest I believed I knew better than anyone.

Except I did not know this forest at all. Not this version of it, with its subtly altered landmarks, impossible paths and the thing that moved through the darkness like smoke, taking people without leaving a trace.

"The beck," I said, forcing my mind back to what we could still control. "We reach the beck, follow it downstream and find a forest road or managed route."

Nia nodded and fell into step beside me. Her breathing was steady and deliberate. Whatever fear she felt, she refused to let it paralyse her.

Good. I needed her focused if either of us was to survive.

The voices began behind us.

Aiden called for help. Owen cried out in pain. Martin shouted my name. Even Chloe begged us not to leave her alone, her voice weak and frightened.

The thing possessed all of them now, a chorus of the missing attempting to lure us back into the trees.

I kept moving, although every instinct demanded that I help. Their voices sounded so real and so desperate that part of me believed they might truly be alive and awaiting rescue.

But they were gone. All four of them. Whatever used their voices wanted Nia and me to join them.

Wet ground spread across the path ahead, black water gleaming in the weakening beam. We left the packed earth and forced our way through bracken and old coppice, angling towards the sound of the beck. The enclosed woodland seemed to rearrange itself around us. Conifers gave way to twisted hazel stools and alder, then closed in again where no such trees should have stood.

My head torch began to weaken, its beam yellowing at the edges, but it had not failed. I did not dare stop to search for the spare torch buried in my rucksack.

"Callum," Nia said beside me. "The water should be closer than this."

"I know. Keep moving."

A patch of bracken thrashed to our left. I turned the weakening beam towards it and caught only wet fronds snapping back into place.

Nia remained at my shoulder.

Then Owen screamed from somewhere directly behind us.

We both looked back. My light swept across the path we had made through the bracken, illuminating crushed stems, black mud and nothing else.

Something whispered from ahead in Daniel's voice.

"Callum, please. I can't find my way back. I'm scared."

Nia gripped my sleeve. "Which way?"

The head torch flickered, dimmed, then steadied again.

"Straight on," I said. "Do not let go of me."

We pushed into a dense stand of young spruce. The branches clawed at our clothes and rucksacks. I raised one arm to shield my face and felt Nia's hand slip from my sleeve.

"Nia?"

"I'm here," she answered immediately from behind my right shoulder.

I turned the beam. She was scarcely two metres away, ducking beneath a branch, her face strained but unmistakably hers.

Then the light weakened to a dull orange glow.

For less than a second, the trees between us became a lattice of black bars.

Nia cried out.

I lunged towards her and saw her jerk backwards, not as though pulled by an arm or rope, but as if the darkness itself had folded around her waist. Her boots furrowed the mud. Both hands reached for me.

I caught her wrist.

Her skin was warm and slick with rain. For one desperate moment I held her, bracing myself against a spruce trunk while an immense force drew her into the trees.

"Don't let go!" she screamed.

I tightened my grip, but something moved behind her. In the failing light I saw no body, only a depth of blackness that did not belong between the trunks, filled with momentary suggestions of faces. Chloe. Martin. Aiden. Owen. Each appeared and vanished across its surface like reflections on disturbed water.

Nia's wrist twisted violently in my hand. My fingers slipped.

She was wrenched backwards into the dark coppice.

"Nia!"

Her scream receded with impossible speed. Branches shook once, then became still.

I threw myself after her, sweeping the head torch between the trunks. The beam remained weak but had not yet died. It showed wet ground, broken bracken and two short grooves left by her boots. The marks ended after three metres.

There was no blood, no body and no continuing trail.

"Callum!" Nia shouted from somewhere far to my left. "It's got me!"

I turned towards the voice.

Then she called from my right, in precisely the same words and tone.

"Callum! It's got me!"

A third Nia screamed directly behind me.

I ran.

My legs were finished. Three more steps and I felt certain I would collapse into the wet needles and dead leaves, but I forced myself onwards. The head-torch beam bounced wildly with every stumbling stride, throwing frantic shadows across tree trunks and low branches that appeared to reach for me.

My lungs burned. Each breath felt like swallowing glass, and the cold air made it worse.

Behind me, the voices continued.

"Callum, please don't leave me here."

That was Owen, but Owen was gone. I no longer knew how long ago the thing had taken him. Time had ceased to mean anything in the forest. Yet it remembered exactly how he sounded: every inflection, every nervous catch in his throat when fear took hold.

I stumbled over a fallen branch and nearly went down, saving myself against the trunk of a conifer. The bark scraped my palm raw, but I scarcely felt it.

My head torch swept across the forest floor. It revealed nothing but more trees extending into darkness in every direction. There was no path, no marker and no visible watercourse, only the sound of the beck and my own ragged breathing.

"Callum."

Now Aiden's voice came from perhaps thirty metres behind me.

"Mate, I can't find the path. Where did you go?"

Aiden, who had seemed so confident earlier as he examined the old red-deer tracks. Aiden, who had wanted to help everyone, who had tried to return for Martin and Chloe.

The thing reproduced his voice perfectly, including the slight accent that became more noticeable whenever he grew excited.

I forced myself onwards although my legs felt boneless. The head torch faded further. How long had I been running? It felt like hours, but it might have been twenty minutes. Time meant nothing there. Nothing mattered except placing one foot before the other and refusing to stop.

"Please, Callum. I'm hurt."

Chloe's voice now, young and frightened.

"I think my ankle's broken. I can't walk."

That voice struck harder than the others.

Chloe had been out of her depth from the beginning, wearing trainers on a survival course as if she were going to a shopping centre. She had trusted me to keep her safe.

They all had.

And I had failed every one of them.

But Chloe was dead.

Four of them were gone. Martin and Chloe had vanished during our first blind flight from the cottage, Aiden on the main path, and Owen shortly afterwards. Nia was the only trainee I had left.

She ran beside me through the mixed conifers, matching me step for step as bracken whipped at our legs and wet branches dragged across our jackets. My headlamp was weakening, its narrow beam turning yellow at the edges, but it had not failed. I could still see Nia whenever she crossed in front of it.

Then Chloe screamed from somewhere behind us.

"Callum! Please, I can't walk. My ankle's broken."

Nia faltered.

"Keep moving," I told her.

The voice came again, perfectly pitched between pain and panic. "Nia, don't leave me here. Please."

We both knew Chloe was gone. We had heard the same thing imitating Martin, Aiden and Owen. But knowledge did not silence instinct, and Nia glanced over her shoulder for no more than a second.

Something moved through the bracken beside her.

A pale hand shot from the darkness and closed around her rucksack strap. Nia cried out as she was jerked sideways. I caught her wrist with both hands and hauled back. For one terrible moment I had her. Her fingers dug into mine, her face stark in the fading headlamp beam.

"Don't let go," she gasped.

The thing pulled again. The strap bit into her shoulders. I tried to reach my legal folding rescue knife, buried in my rucksack, but I could not release her without losing her. The darkness behind Nia seemed to swell between the trees. Faces surfaced in it and vanished - Chloe, Martin, Aiden, Owen - each one opening its mouth in a different cry.

Nia's grip slipped.

I lunged after her, caught two fingers, then one. The thing gave a final wrench and dragged her into the bracken. I followed for several metres, crashing through wet growth, but there was no trace of her. No movement. No broken branches. No sound except my own breath.

Then Nia called from directly behind me.

"Callum, I've got away."

I ran.

Five people had been entrusted to me. Four had already been taken before that moment, and now Nia was gone as well. Whatever had taken them was using their voices, cycling through them like a radio scanning stations, searching for the frequency that would break me down and make me stop running.

"Callum, why did you leave us?"

Daniel's voice cut through the night, and I nearly fell.

"I thought you cared about us. I thought we were family."

Daniel Hargreaves, my brother, had been dead for three years. He had never met any of the five trainees. Yet the thing knew his voice and knew exactly how to use it against me.

He sounded hurt and disappointed, using the same tone he had used during our last conversation, when I told him his climbing stunts were becoming too dangerous. Three days later, he died in a climbing accident in Eryri.

I crashed through a patch of low scrub, branches tearing at my jacket. I had to keep moving. I could not let it catch me. But my body was shutting down, running on nothing except adrenaline and fear, and my vision had begun to narrow.

Even with the headlamp, there was only a thin beam of light in an ocean of black.

"You always were a coward, Callum."

Daniel's voice again, but different now. Angry. Bitter.

"Running away when people need you, just like you ran away from me."

That was not Daniel. He had never spoken to me like that, not even when we fought. The thing was becoming desperate and trying different approaches. Knowing the words were false did not make them hurt any less.

I stumbled into a small clearing and had to stop, hands braced on my knees while I fought for breath. The headlamp revealed a circle of conifers, their trunks black and massive in the darkness. There was no way to tell which direction I had come from and no obvious route onwards.

"Callum, I'm so scared."

Nia's voice came from the trees behind me.

"It's got me. It's got me and I can't get away. Please help me."

Nia had been composed and confident. She had stayed beside me until the thing tore her from my hands. Now her voice sounded terrified, broken in a way I had never heard before. Even knowing it was an imitation, every instinct screamed at me to turn round and find her.

But Nia was gone, just like the others.

I straightened and tried to think through the exhaustion and panic. The thing was getting closer. I could hear movement among the trees, branches breaking beneath something heavy.

It no longer needed to be quiet. It knew I was trapped and running out of strength.

"Please, Callum. It hurts so much."

Chloe was sobbing now.

"Why won't you help me? Why won't anyone help me?"

Every word had been chosen with precision, calculated to tear at what remained of my conscience. The thing understood human psychology. It knew exactly which wounds to press. It had been hunting people for a long time, learning from each one it took.

That was when I remembered the warning Aiden had found in the cottage, tucked beneath the small oak document chest on the bench inside the entrance.

When shadows move and stolen spirits call, Turn true light upon them all. Where light breaks through the night's disguise, The borrowed face reveals the lie.

I had been so intent on escape that I had not properly considered what it meant. Standing in that clearing with only my failing headlamp between me and absolute darkness, I understood.

The warning was about direct light.

The cottage had been preserved perfectly, as though waiting to be found, and the document chest had been placed where no visitor could miss it. What if the cottage, the faceless portrait and the warning were all connected? What if someone who had lived there had encountered this creature before?

"Callum, I can see you."

Owen's voice was much closer.

"I'm coming to get you. Stay where you are."

The movement grew louder. Branches cracked as something large pushed through the undergrowth without attempting stealth. It thought it had driven me into a corner.

Perhaps it had. But perhaps that did not matter.

I looked down at the headlamp and watched the beam flutter as the battery weakened. It was barely strong enough to show three metres ahead, but it was all the light I had ready to hand.

Where light breaks through the night's disguise, the borrowed face reveals the lie.

What if that was literal? The creature had avoided direct illumination, remaining among the shadows and taking people when they became separated. It had waited until full darkness before beginning the hunt in earnest. When it dragged Nia away, it had struck from outside my weakening beam.

"Callum."

Nia's voice again, but different this time. Closer.

"Callum, I found you. Everything's going to be all right now."

I turned slowly and directed the headlamp towards the sound.

At the edge of the clearing, perhaps six metres away, something moved between the trees. It was tall and human-shaped, approaching with steady, measured steps.

"Thank God you stopped running," it said in Nia's voice. "I've been looking everywhere for you. The others are safe. We found a way out."

The figure stepped into the outer edge of my light, and my blood turned cold.

It was Nia. Exactly Nia. The same height and build, the same dark hair pulled into a ponytail, the same walking clothes and confident posture. If I had not felt her fingers slipping from mine, I might have believed she had escaped.

But I knew better.

"Callum, what's wrong?" the thing wearing Nia's face asked, tilting its head with perfect concern. "Why are you looking at me like that?"

Even the expressions were right: the slight furrow between her brows when she was confused, the way she held her shoulders while trying to assess a situation. It had studied her and learnt every detail and mannerism.

But the eyes were wrong. They reflected the headlamp like an animal's, returning a cold light with nothing human behind it.

I was finished with running. My legs would not have carried me another fifty metres, and there was nowhere left to go. The thing had been herding me deeper into the forest, through conifers, wet ground and old coppice, away from any chance of help. It could continue all night, using the voices of my trainees and my brother until I collapsed.

But perhaps I did not have to run any more.

I adjusted the headlamp and aimed its beam directly into the creature's face. It flinched and took half a step backwards, although it maintained Nia's concerned expression.

"Callum, you're frightening me," it said in her voice. "What happened out there? Where are the others?"

The light was bothering it. It was not strong enough to cause serious harm, but the creature could not comfortably endure it.

The warning had been right. Light was the key. But my headlamp was fading fast, and I needed more than a dying lamp to stop something capable of perfectly imitating the missing.

I thought again of the cottage: the rooms preserved beyond reason, the portrait above the fireplace showing a woman in a pale blue dress beside a dark lake, her face deliberately smeared away, and the oak document chest left inside the entrance as a message for whoever came next.

Someone had fought this thing before. Someone had discovered how to hurt it and left a warning.

The creature took another step forwards, remaining at the edge of the beam.

"Callum, please," it said.

Tears filled its eyes, perfect tears that caught the light and glittered like real ones.

"I don't understand what's happening. I'm confused and frightened."

I was no longer deceived. I knew what it was, and I knew what I had to try.

Keeping the headlamp trained on it, I dragged my emergency kit from my rucksack and pulled out the red hand-held distress flare. The creature's eyes widened as I removed the cap and struck the igniter.

The flare erupted in a brilliant red blaze, hissing and throwing harsh light across the clearing. The thing wearing Nia's face shrieked in a voice that was nothing like hers. It staggered backwards and raised both hands to shield its eyes.

Now I had a weapon.

I held the flare high. Red light washed over the trees in savage waves as the creature retreated another step, its animal eyes reflecting the flame like polished glass.

The sight turned my stomach. Everything else remained perfect: the set of Nia's shoulders when she was nervous, the slight inclination of her head, even the small scar on her chin from a childhood fall. Only those eyes betrayed it.

My headlamp was still strapped to my forehead, producing little more than a weak yellow glow. I fumbled for its switch, trying to coax every remaining second from the battery. The creature flinched when I brought both lights to bear on its face.

Then its features shifted.

For a second, Nia's face became Aiden's, wearing the absorbed expression he had shown while identifying the old red-deer tracks that led us towards Bogle Beck. The face flickered again and became Owen's eager smile, the one he had flashed while taking photographs on his mobile.

"Callum, please."

It was using Nia's voice again, but the movement of its mouth no longer quite matched the words.

"I don't understand. Why are you pointing that light at me?"

I held both beams steady. The thing was good - far better than good. Without those reflective eyes, I might have believed it was really her. The voice contained precisely the right measure of confusion and hurt. Even the defensive position of its arms matched the way Nia would have reacted to a threat.

But I had watched it take all five people entrusted to me. I had heard it use their voices to lure us apart. Whatever it was and wherever it had come from, it was not human.

It was not Nia.

The headlamp flickered once, then twice, before steadying. It did not have long left. I had to act before it failed completely.

"You're not her," I said, forcing my voice to remain level. "I don't know what you are, but you're not Nia."

The creature tilted Nia's head in her characteristic way.

"Callum, you're frightening me. It's me. Look at me. Really look."

I was looking. That was the problem. Every detail was perfect, down to the freckle near her left ear and the way loose strands of hair crossed her forehead.

If I had not known better, I would have lowered the lights and apologised. Instead, I stepped back and maintained the distance between us.

The flare hissed and spat sparks, casting wild shadows across the trees. Its red light made the clearing look like a vision of hell, but it was working. The creature no longer advanced. If anything, it appeared to be struggling to maintain Nia's form under direct illumination.

"The warning," I murmured. "The borrowed face reveals the lie. It was literal. Light hurts you."

The creature arranged its features into confusion, but another face flickered beneath them. For an instant, Martin's worried expression replaced Nia's. Then it snapped back like a television changing channels.

"What warning?" it asked in Nia's voice. "Callum, I think you hit your head when you fell. You're not making sense."

But for the first time that night, I was making perfect sense. Someone else had met the creature. Someone had survived long enough to discover its weakness and leave instructions for the next person who stumbled into its territory.

The portrait in the cottage had not been an eccentric artistic choice. The woman with the obliterated face had been a warning about what the creature stole.

The headlamp dimmed noticeably. It had perhaps thirty seconds left. The flare would last longer, but not by much. I needed to finish this.

I raised my chin, angling the headlamp directly into those hollow eyes.

The effect was immediate. The creature released a low, pained moan that did not belong to Nia. It seemed to rise from somewhere deep within its chest. The perfect features wavered like heated air above a road.

"Stay back," I warned, although I did not know whether it could understand me any longer.

The human facade was beginning to split. It tried to step towards me, but the combined light created a barrier it could not cross. Its movements became abrupt and unnatural.

Nia's face flickered. Aiden. Owen. Martin. Chloe. Then faces I had never seen - old and young, men and women, all wearing expressions of pain and terror.

How long had the creature been there? How many people had it taken? The forester's cottage had appeared abandoned for decades, perhaps longer.

The headlamp gave one final pulse and died.

The creature surged forwards at once.

I still had the flare. I thrust it towards the creature's face until the red fire was only centimetres from its skin.

Its shriek made my earlier thought of hell seem inadequate. This was pure agony, the cry of something burning from within.

The perfect features began to melt, not as flesh melts but as an illusion collapsing under assault. Nia's face stretched and distorted. Her eyes became empty black sockets and her mouth opened impossibly wide. Other faces surfaced and disappeared in rapid succession - all the people it had taken, all the identities it had stolen.

I held the flare steady, although my arm ached violently. The creature writhed and twisted, unable to escape the direct light. The stolen faces peeled away one after another, exposing something darker beneath.

At last, mercifully, the screaming stopped.

Where the entity had stood, there was nothing. Not empty space, but an absence: a patch of darkness that swallowed the flare's light instead of reflecting it. It had no stable shape or substance. Looking directly at it made my eyes ache.

The darkness divided under the flare's glare, splitting into ragged strands that recoiled between the trees. For a moment they hung there, thin as smoke and blacker than the forest behind them. Then they pulled apart and vanished.

The clearing was empty except for me and the hissing flare.

Wind passed through the conifers with a sound like distant waves. Ordinary forest noises returned: small animals rustling in the undergrowth, branches creaking as they settled, water moving somewhere beyond the trees. The oppressive silence that had descended after we found the cottage began to lift.

I stood with the flare raised, waiting for the creature to re-form. The forest felt different, cleaner, like a fever breaking, but I refused to trust that feeling. The flare was burning down quickly, with perhaps two minutes remaining.

The presence that had hunted us seemed gone. I could feel its absence in the way one notices the sudden end of a headache. Even so, it had been clever and patient, and had used perfect mimicry against us. I would not assume it was dead merely because I could no longer see it.

The flare guttered out roughly ninety seconds later. I remained still in the complete darkness, listening.

Nothing approached. No stolen voice called my name.

I opened my rucksack by touch and dug beneath the emergency kit until I found my spare torch. Its fresh batteries gave a clean white beam. I swept it slowly around the clearing and then kept watch for much longer, checking every trunk, every patch of bracken and every gap between the trees.

An owl called in the distance. Something small hurried through fallen leaves. There was no sign of the predator, no body and no residue from the darkness the flare had driven apart.

The forest night felt ordinary again, the sort I had known throughout my years as an outdoor instructor. At the time, I believed the light had destroyed the thing. I had no proof, only the silence it left behind.

I needed to leave. I had to reach the Forestry England wardens' office beside the visitor centre and report five missing people. There would be mountain-rescue teams, police officers and questions I could not answer, but those were problems for later. First I had to escape the forest.

I checked the compass stored with my navigation kit and compared it with the last reliable GPS position I had seen. The main managed path should have been roughly seven hundred metres to the south-east. In daylight, with recognisable landmarks, it would have been straightforward. At night, after the false path had twisted every familiar reference point and made the GPS heading behave impossibly, it was more difficult, but not beyond me.

I began walking, choosing my way through the undergrowth. Every few steps I stopped and listened for pursuit. Nothing followed.

Reaching the path took longer than expected. I had to negotiate wet ground, fallen timber and dense bracken, repeatedly checking my compass to avoid circling back. Eventually the spare torch picked out the compacted surface of the main walking route.

I had never been so relieved to see a path.

From there I followed it towards the forest trailhead and car park. My legs felt loose and unreliable, and exhaustion closed in as the adrenaline drained away. Still, I kept moving, putting one foot before the other and increasing the distance between me and the impossible cottage that had begun the nightmare.

The lights of the Forestry England wardens' office beside the visitor centre appeared ahead. It was a low building with solar panels on its roof and a small staff parking area. Someone was inside.

I ran the final hundred metres, my boots hammering the gravel of the car park. Human voices had never sounded so welcome.

The door opened before I reached it. A woman in Forestry England uniform stepped outside carrying a mug of coffee. She nearly dropped it when she saw me stumbling across the gravel.

"Good God. What happened to you?"

I must have looked dreadful. My jacket was torn in three places. Mud caked my trousers from knee to boot, and dried sweat and tree resin tightened the skin of my face. The chemical stench of the flare clung to my clothes.

"I need to report five missing people," I said. "They're my trainees."

The name badge on the woman's uniform read PRIYA NAIR. Forestry warden Priya Nair guided me into a small office smelling of coffee, printer paper and damp waterproofs. Fluorescent tubes hummed overhead, painfully bright after hours among the trees.

She gave me water, reached for a notepad and called 999. She told the operator that five walkers were missing in Grizedale Forest and asked for Cumbria Constabulary and mountain rescue. Then she sat opposite me.

"Start at the beginning."

I did.

I told her about the training group, Aiden identifying old red-deer tracks towards Bogle Beck, and the subtle turn away from the planned route. The bivouac clearing should have been about three kilometres away, yet the GPS had placed us roughly seven hundred metres off route even though the landmarks and headings had seemed to shift around us.

I described the low stone-and-timber forester's cottage, with its slate roof and narrow veranda. I told her about the oak document chest Aiden found on the bench inside the entrance and the warning tucked beneath it. I explained how the scream had sent us fleeing, how Martin and Chloe disappeared during that first flight, how Aiden vanished on the main path and Owen shortly afterwards, and how the creature dragged Nia from my hands while the headlamp was weakening.

Priya recorded names, ages, clothing, medical information and emergency contacts. She showed no reaction when I described voices calling through the forest in perfect imitation of the missing. She did not interrupt when I told her that the entity had worn Nia's face.

"This creature," she said when I had finished, her pen hovering above the page. "Can you describe it more precisely?"

"It could look like anyone. The copies were perfect, but the eyes were wrong. They reflected light like an animal's. When I used the flare, the stolen faces began to peel away. Then the darkness inside it split apart."

She continued writing with calm professionalism. For a few minutes, I thought she believed me, or at least accepted that the details mattered.

"Search teams are being organised," Priya said. "Can you guide us to where this happened?"

Relief flooded through me. Someone was listening.

About two hours later, I led a joint party of Forestry England wardens, mountain-rescue volunteers and two Cumbria Constabulary officers into the forest. Food and water had steadied me, and determination carried me when my legs threatened to fail.

These people understood woodland searches. They would find evidence. Then they would understand.

I knew the route. Even in darkness, I remembered every turn and landmark. The place where the path had seemed to draw us away from the proper route was exactly where I expected it to be, although the gap between the trees now looked narrower and less distinct.

I led the team through it and retraced the line we had followed towards the cottage.

There was no cottage.

The clearing was present, approximately the right size and shape, but the low stone-and-timber building had vanished. There were no foundations, fragments of slate, rotted beams, rusted fittings, trampled vegetation or marks where any structure might have stood.

"It was here," I said, sweeping my torch across the bare ground. "The front door faced that way."

Police Constable Graham Holt, a broad man whose lined face suggested decades of service, crouched to inspect the soil.

"I can't see evidence of a recent structure," he said. "Or an old one."

"There was a stone fireplace," I insisted. "A table, chairs and shelves. A portrait above the fireplace - a woman in a pale blue dress beside a dark lake, with her face smeared away."

Priya walked the perimeter.

"The ground looks undisturbed," she said. "There are no removal scars or vegetation patterns suggesting a building stood here."

I knew what I had seen. The cottage had been solid. Aiden had walked around it and examined the structure. All six of us had gone inside. The oak chest and warning had been on the entrance bench.

"Perhaps I've got the exact position wrong," I said, although I knew I had not. "We should search the surrounding area."

We spent the next three hours examining the nearby woodland. The team worked methodically, following bearings through the relevant compartment and checking adjacent ground. They found red-deer tracks, traces of old bivouacs and litter left by previous visitors.

They found no cottage and no evidence that one had ever existed there. They found no sign of my trainees.

The intensive search continued for six days. Forestry England wardens, mountain-rescue volunteers and Cumbria Constabulary officers covered the relevant forest compartments, watercourses and adjoining routes. Police and mountain-rescue search-dog teams worked from the last reliable locations. A National Police Air Service helicopter used thermal imaging above the canopy.

They checked Bogle Beck downstream towards managed paths and forest roads. They searched steep ground, culverts, old coppice, outbuildings and every plausible shelter in the target area.

They found nothing.

I stayed at a local inn and rang Priya twice a day for updates. Each conversation was shorter than the one before, professional courtesy thinning under the pressure of an impossible account.

On the fourth day she asked me to return to the wardens' office.

Topographical maps and search grids covered her desk.

"Teams have been working around the clock," she said. "We've searched the relevant compartments, the watercourses and the connecting routes. There is no trace of your trainees and no evidence of the cottage you described."

"It was there."

"I know that's what you remember, Callum." Her use of my first name felt like a warning. "I need to ask about your condition on 12 September. Had you been drinking or taking medication? When had you last eaten?"

The questions continued. Had I been under unusual stress? Had I slept properly? Did I have any history of hallucinations or drug use?

Each one felt like a small betrayal, chipping at the truth I knew.

"You think I invented it."

"I think you experienced something traumatic. But no physical evidence supports the events as you've described them."

Two days later, Detective Inspector Helen Ward of Cumbria Constabulary CID took control of the missing-person investigation. She had grey hair and sceptical eyes that suggested long experience of accounts which failed to fit the evidence.

"Let's go through this again," she said, sitting opposite me. "Five people entered Grizedale Forest under your instruction on 12 September 2025. None of them returned. You did."

"I've told you what happened."

"You've described a creature for which we have no evidence and a cottage that does not appear on Forestry England maps, historical records or the ground itself."

DI Ward opened a file.

"I've reviewed your background. Eight years with Fellcraft Outdoor Training and a clean safety record. Then, three years ago, your brother Daniel died in a climbing accident in Eryri. You were meant to climb with him but withdrew shortly beforehand. He went without you and fell."

My stomach tightened.

"That has nothing to do with this."

"Survivor's guilt can affect memory and judgement in complex ways. People under extreme pressure can construct explanations for events they feel unable to accept."

The room seemed to shrink.

She leaned forwards, her voice adopting a practised sympathy that made my skin crawl.

"What actually happened in the forest, Callum? Did you make a navigational error? Did that error lead the group into dangerous terrain? Was somebody injured, after which you panicked?"

"I've told you exactly what happened."

"Have you? Because your account depends upon a disappearing building and a supernatural predator. That is not an explanation investigators can accept without evidence."

The questions became accusations. Where were the missing people? Had I concealed them somewhere in the forest? Was there a financial motive or some fraudulent arrangement?

DI Ward offered versions of events in which I was anything from a traumatised instructor with corrupted memories to a calculating killer. I refused to answer further questions without a solicitor.

The official interim report was issued two weeks after the disappearance. It recorded five walkers as missing and presumed dead through exposure, terrain hazards and navigational error. It criticised an unexplained error by an experienced outdoor instructor and noted that I had emerged in severe psychological distress, reporting supernatural events that could not be corroborated.

There was no meaningful reference to the voices or the entity in the public account. Nothing about the creature wearing Nia's face while the flare stripped away its stolen identities.

The families received copies of the report. Owen's parents, Aiden's sister, Chloe's grandmother who had raised her, Martin's former wife and teenage daughter, and Nia's brother in Manchester all knew my name.

They knew I had taken their loved ones into Grizedale Forest and returned alone.

I tried to contact some of them. I wanted to explain what had really happened. Owen's mother ended the call. Aiden's sister warned that she would ring the police if I contacted her again. The others refused to speak to me.

Three weeks after 12 September, I sat in the office of Dr Eleanor Shah for a compulsory fitness-for-work assessment. She was younger than I was, with kind eyes and a gentle voice that somehow made everything worse.

"The mind has ways of protecting us from trauma," she said. "Sometimes it creates an alternative narrative because the underlying event is too painful to process directly."

"You think I'm lying."

"I think you believe what you've told me. Belief and objective reality are not always the same thing."

She recommended medication for anxiety and depression, regular therapy and an extended period away from outdoor instruction.

Everyone had settled upon the same truth. Callum Hargreaves, an experienced instructor, had made an unexplained navigational error, suffered a psychological breakdown and constructed an elaborate fantasy to account for the loss of five people in his care.

The alternative - that something inhuman hunted among the trees of Grizedale Forest - was too impossible to consider.

That night, I sat in my rented woodland cottage and stared at the official report. Five people, missing and presumed dead. No acknowledgement of what I believed had taken them.

There had been no remains in the clearing, nothing to prove the flare had killed the creature. At first I had believed the light destroyed it, but certainty became harder to sustain. It might still be in the forest, hunting, while nobody looked for it because nobody believed it existed.

Truth was useless if no one accepted it. I could keep insisting upon what I had seen, what I had fought and what I had barely escaped. That course promised only more questions about my sanity, greater suspicion about my involvement and deeper isolation from a world that had already decided I was either ill or criminal.

I understood the choice. I could accept their version - a tragic navigational error followed by trauma and psychological collapse - or continue telling an impossible truth that made me look guilty of something worse than survival.

But I knew what had happened to Nia, Aiden, Owen, Chloe and Martin. I believed the creature had killed them, even if no bodies had been found and the official position remained that they were missing and presumed dead.

I knew what I had seen among the trees: stolen faces and the voices of the missing. The report could blame exposure, terrain hazards and navigational error, but I could not.

On Tuesday, 10 March 2026, six months after the disappearance, I handed in my resignation.

The paperwork felt heavier than two sheets of paper should. It ended eight years with Fellcraft Outdoor Training and a career spent leading people through forests I could no longer bear to think about.

My supervisor, Ruth Palmer, read the letter twice, her reading glasses perched on her nose while I sat opposite her desk and tried not to fidget.

"This is sudden, Callum," she said, setting the pages down. "You've been on leave since the incident, but I thought you might ease back into things. Day sessions, perhaps. Familiar routes."

Familiar routes.

The phrase made my stomach contract. Even imagining trees around me sent my pulse racing. Three weeks earlier, I had driven to the Tarnside Fell beginner route, one I had used countless times. I managed perhaps fifteen metres beyond the car park before turning back. My hands shook on the steering wheel all the way home.

"I can't do it any more," I told Ruth. "Outdoor instruction. I'm finished."

She nodded slowly, as if she had expected the conversation.

Everyone at Fellcraft knew what had happened, or at least knew the official account: a tragic incident in which five trainees disappeared and their sole surviving instructor suffered severe psychological trauma.

It was a story that made sense to people who lived in a world where creatures did not steal faces or mimic the voices of the missing.

"Have you decided what you'll do next?" Ruth asked.

I had spent weeks thinking about it while lying awake at 03:00 in the rented cottage, staring at the ceiling and listening to every creak and settling noise.

The cottage stood amid several hectares of woodland. Through the bedroom window I could see the same mixture of trees that had surrounded the impossible forester's cottage where Aiden found the warning and everything went wrong.

I could not remain there.

"I'm moving to Manchester," I said. "A friend there thinks he can find me building work."

Ruth raised an eyebrow.

"Building work? Callum, you've been instructing since you were twenty-two. You know the fells and forests better than almost anyone."

That was precisely the problem. I knew what might still be waiting among them for the next group to stray from a familiar route. I could not say that without sounding as though I belonged on a psychiatric ward.

"I need a change," I said. "A complete one."

Ruth signed the paperwork without further questions.

I cleared my desk, gave up the rented woodland cottage and loaded my belongings into a van. Later that March, I left Cumbria and the landscape that had defined my life for more than a decade.

Manchester felt like another world. Concrete, brick and steel replaced conifers and stone. Traffic replaced birdsong. Crowded pavements replaced empty paths.

I rented a studio flat on the fourth floor of a converted industrial building near New Islington and Ancoats. No trees were visible from the windows, only streets, brick buildings and the continuous movement of the city.

The noise unsettled me at first. I had grown accustomed to woodland quiet. After several weeks, however, I realised that the urban din helped. It covered other noises - sounds that might not have been real but could still wrench me awake at 02:00.

My friend Lee Foster found me work with his building crew, mostly renovating houses. The physical labour felt good and unexpectedly familiar. My hands had always been more comfortable with tools than words, whether I was preparing a bivouac or repairing a floor.

The others did not ask many questions. Lee had told them I was leaving outdoor work, and that explanation satisfied them.

The nightmares began about two weeks after I moved to Manchester.

I woke gasping, the sheets soaked in sweat, with the taste of fear and the imagined bitterness of tree resin thick in my mouth. In every dream I was running through Grizedale Forest again, my headlamp weakening while voices called from the darkness.

Owen begged me not to leave him. Aiden said he was lost and needed help. Chloe sobbed about her broken ankle. Nia cried out as her fingers slipped from mine.

And always Daniel's voice cut through the others like a blade.

"Callum, where are you? I'm scared. Callum, please don't leave me."

The first few times, I bolted upright and reached immediately for the bedside lamp, flooding the flat with light. I would remain awake for an hour or more, fully dressed, examining every corner and shadow until my pulse slowed.

The rational part of my mind knew I was safe. I was on the fourth floor behind a locked door, hundreds of kilometres from Grizedale Forest.

Rationality had little power at 03:00, when Daniel's voice still echoed in my ears.

After the fifth or sixth nightmare, I began sleeping with every light on. It helped, mostly. The flat remained bright throughout the night: ceiling light, desk lamp, reading lamp and the bathroom light with the door ajar.

My electricity bill doubled. I did not care.

Light had saved my life when the creature wearing Nia's face tried to reach me. Direct illumination had stripped away its stolen features and driven its central darkness apart. I would not take chances.

The neighbour below complained about the glow through my windows. She said it kept her awake. I bought blackout curtains and continued leaving the lights on.

Work became my anchor. Eight hours a day spent concentrating on measurements and materials, learning unfamiliar techniques and tiring my body enough that sleep might come more easily.

The crew was renovating a Victorian terrace in Ancoats, removing old wallpaper and replacing rotten floor joists. The detailed work demanded concentration. I gave it everything, volunteering for overtime and staying late to finish jobs that could easily have waited until morning.

Lee noticed my dedication but misunderstood its cause.

"It's good to see you getting back on your feet," he said one afternoon as we took a break outside the house. "Whatever happened in those woods really knocked you sideways for a while."

I nodded and took a long drink from my water bottle. Lee knew the basic story. A walking accident. Five people missing and presumed dead.

I had survived. He did not know about the creature, or the voices, or the way light had been the only thing standing between me and whatever fate had claimed my trainees. Nobody knew that part except the Forestry England wardens and Cumbria Constabulary officers, who had dismissed it as a trauma-induced hallucination.

"Time heals," Lee continued. "You just have to give it space to work."

Time. The six months since 12 September 2025 sometimes felt like six years, and at other times it seemed the whole thing had happened yesterday. I could still smell the chemical burn of the red distress flare. I could still see the creature's features shifting and melting under the direct light, still hear the screams of its stolen faces as they were stripped away layer by layer.

"Yeah," I said. "Working on it."

My therapist was Dr Imogen Clarke, recommended through the employee assistance programme at Lee's construction company. Her office was on the fifteenth floor of a city-centre building, with windows overlooking the River Irwell. It was clean and professional, with certificates on the walls and a bookcase full of psychology texts. Nothing like the outdoor therapy some people had suggested, which would have involved walking and reflective exercises in the countryside. I had made it clear that such an approach was completely out of the question.

"Tell me about the nightmares," Dr Clarke said during our third session. "You mentioned that they recur, with the same scenario each time."

She was perhaps forty-five, with greying hair and a calm manner that probably worked well with most patients. I shifted in the leather chair opposite her desk. We had covered the basic chronology in our first two meetings: the training expedition on 12 September 2025, the navigational error, and the disappearance of the five people entrusted to me. It was the official version, sanitised for professional consumption.

"I'm running through the forest," I said. "I hear voices calling for help. People from the group who didn't make it out."

"That is a common trauma response," she said, making notes on her pad. "Survivor's guilt manifesting as auditory hallucinations. Your mind is processing the guilt you feel about being unable to save them."

Auditory hallucinations. The clinical term made it sound manageable, like a symptom that could be treated with the right combination of therapy and medication. She had already prescribed small white tablets for anxiety and depression, which I took every morning with coffee. They softened the panic attacks, but did little for the dreams.

"The voices," Dr Clarke continued. "Do they say specific things, or are they more general calls for help?"

This was where I had to be careful. The truth was that they said very specific things, exact phrases I remembered from that night.

Owen's desperate plea: "Please don't leave me, Callum."

Aiden's bewildered voice: "I'm lost. I can't find the path."

Chloe, choking with pain: "My ankle's broken. I can't walk."

And Daniel.

Daniel's voice repeating things he had actually said three years earlier, during our final conversation. Word for word.

"General things," I lied. "They call my name and ask for help."

She nodded and wrote something down.

"And you mentioned that one of the voices belongs to your brother, Daniel, who died several years ago. That is particularly significant from a psychological perspective."

I had made the mistake of mentioning Daniel during our second session. I had been trying to explain why that particular voice affected me so strongly, but I had framed it as my traumatised mind combining past grief with the more recent loss, not as evidence that something in Grizedale Forest had somehow reached into my memories of my dead brother.

"Trauma has a way of drawing our deepest fears and losses to the surface," Dr Clarke explained. "Your brother's death was clearly a significant emotional event, and now your mind is connecting that loss with the recent disappearances. It is creating a narrative in which all the people you could not save are calling out to you."

From her perspective, the explanation made perfect sense. A textbook trauma response. Survivor's guilt. Complicated grief. All treatable, given time and proper therapeutic support.

She had no way of knowing that Daniel's voice in the forest had repeated the precise words he had used during a telephone call three days before the climbing accident in Eryri that killed him. He had rung to ask whether I would join him on what became his final climb.

"I'm scared about this route, Callum. It's more technical than anything I've done before. I could really use a spotter."

I had been busy that weekend, distracted by work and a relationship that was falling apart. I told him I could not make it. I said he should find someone else or choose an easier climb.

Three days later he was dead, killed in a fall from a rock face he had attempted alone because I had not been there to talk him out of it.

The creature in Grizedale had known those words. It had spoken them in Daniel's exact voice, with the same nervous energy I had heard during that call. There was no way my traumatised mind could have invented that degree of detail.

But I could not tell Dr Clarke without undermining everything we had built during our sessions.

"The important thing," she said, "is that you are seeking help. Many people in your position try to cope with trauma alone, which often makes matters worse. You are taking positive steps towards recovery."

I nodded, agreed and arranged another appointment for the following week.

The therapy helped in some ways. It gave me someone to talk to, taught me methods for managing the anxiety and provided medication that made daily life more bearable. But it was all built on the foundation of a lie. Dr Clarke was treating me for a psychological condition when what I had experienced was something else entirely.

The worst part was the doubt that crept in during quiet moments. Late at night, when every light in my Manchester flat was blazing and I lay staring at the ceiling, I sometimes wondered whether she was right. Perhaps my mind had created an elaborate fantasy to protect itself from the reality of losing five people under my supervision.

Perhaps there had been no creature.

Perhaps I had become confused among the conifers, bracken and wet ground, led my group away from the route and wandered in circles while they succumbed to exposure or the terrain and I suffered a complete psychological breakdown.

The official report certainly supported that theory. There was no evidence of a supernatural threat, no trace of the forester's cottage Aiden had found and no indication that anything had happened beyond a tragic disappearance caused by exposure, terrain hazards and an unexplained navigational error by an experienced outdoor instructor. Everyone, from the Forestry England wardens and police to the families of the missing trainees, had accepted that version of events.

But then I remembered the distress flare in my hand. I remembered the stolen faces melting beneath its direct light and the inhuman screech as the darkness at the creature's centre was driven apart. Those memories felt solid, real and undeniable, more real than anything else from that night.

The doubt was almost worse than the nightmares. At least when I woke screaming, I knew what frightened me. The uncertainty made me question everything: my memory, my sanity, my ability to distinguish reality from a trauma-induced delusion.

In June 2026, nearly three months after I moved to Manchester, I was walking home from work through New Islington and Ancoats when I heard Daniel's voice call my name from an alley between two buildings.

"Callum. Hey, Callum."

I stopped dead on the pavement, my tool bag slipping from my shoulder.

The voice had come from the narrow space between a coffee shop and a vintage clothing shop, about six metres away. It had the same tone, the same inflection and the same slight rasp Daniel had developed after years of climbing in dusty conditions.

My rational mind responded at once. An auditory hallucination, exactly as Dr Clarke had explained. A phantom sound induced by trauma. My brain playing tricks on me. I was tired and stressed, and I probably had not eaten enough at lunch. There was a simple explanation.

But my body reacted before reason could take control. I spun towards the alley, my hand reaching instinctively for a knife that was not there, while my heart hammered against my ribs.

"Callum, I need help. I'm lost."

Those were exactly the words the creature had used in Grizedale, speaking in Daniel's voice to lure me back into the trees.

But this was central Manchester in broad daylight, with dozens of people passing along the busy street. No creature could be here. There could be no stolen faces, no melting features, no inhuman screams.

I forced myself to walk to the mouth of the alley and look inside. It was empty apart from a commercial bin and some scattered rubbish. No Daniel. No creature. Nothing at all. Just an ordinary city alley smelling of refuse and stale coffee grounds.

"You all right, mate?"

I turned and found a man of about my age standing behind me. He wore a food-delivery uniform and looked concerned. I realised I had been staring into the empty alley for several minutes while pedestrians diverted around me.

"Yeah," I said, retrieving my tool bag. "I thought I heard someone calling for help."

He glanced down the alley, then back at me.

"Can't see anyone. You could check in the coffee shop. Maybe somebody needs help inside."

I thanked him and continued home, but the sound of Daniel's voice followed me for several streets.

By the time I reached my flat, I had almost convinced myself that it had been a trauma response, exactly the sort of thing Dr Clarke would have predicted. Stress from work. A normal development of post-traumatic symptoms as the months passed.

But that night, lying in bed with every light in the flat blazing, I could not shake the feeling that Daniel's voice had sounded too real, too immediate, too much like it had in the forest when the creature used him as bait.

I told myself that these were only trauma-induced auditory hallucinations, but they felt disturbingly real and familiar.

Then the sound pierced the window glass as though it were not there at all.

"Callum."

My hands went still above the laptop keyboard.

Three floors below, traffic hummed along the street, but the voice cut through every other sound with perfect clarity. It had the same tone, the same inflection, the same way Daniel always said my name when he needed something.

I pushed myself back from the desk and walked to the window. My reflection stared at me from the black glass, pale and hollow-eyed beneath the overhead light. Beyond it, New Islington and Ancoats stretched away in patches of streetlight and shadow: empty loading bays, parked delivery vans and quiet industrial buildings. It was the sort of urban landscape that should have felt safe after months of avoiding anything resembling woodland.

"Callum, where are you?"

There it was again.

I pressed my forehead against the cool glass and searched the darkness below. Nothing moved except a plastic bag tumbling across the empty street. The voice seemed to come from everywhere and nowhere, the way sound sometimes carried strangely through a city at night.

Dr Clarke would call it a textbook auditory hallucination. A stress response expressed through familiar patterns. She would probably increase my medication and recommend more frequent sessions.

All very reasonable. All perfectly logical.

Except Daniel sounded exactly as he had in Grizedale. Not distant like a memory or blurred like a dream, but immediate and real, as if he stood directly outside the building calling up to my window.

I backed away from the glass and reached for the light switch beside the door. The overhead fitting was already on, but I flicked the switch anyway, needing the reassurance of its solid click. Then I moved through the flat, checking every source of light in turn.

Desk lamp on.

Reading light beside the bed on.

Kitchen strip light on.

Bathroom light on, with the door left ajar.

The routine calmed me, as it had every night since I came to Manchester. Light meant safety. Light meant I could see what was real and what was not. Light meant the creature could not come close enough to steal faces and voices and use them as weapons.

I returned to the desk but could not concentrate on the laptop screen. Outside, Manchester carried on around me. Late-shift workers headed home. Crowds spilled from bars onto the pavements. Ordinary people lived ordinary lives, entirely unaware that something impossible had happened in Grizedale Forest.

The official report lay in my filing cabinet. All twelve pages of bureaucratic language transforming five disappearances into a tragic walking incident. Exposure. Terrain hazards. Navigational error by an experienced instructor whose judgement might have been affected by previous trauma. The investigators had considered every possibility except the truth, because the truth would have got them laughed out of their jobs or referred for psychiatric assessment.

I understood their position now.

Accepting my account meant accepting that something supernatural hunted in those woods, something capable of perfectly imitating human voices and appearances. It meant admitting that all their training, equipment and procedures were useless against a threat that should not exist. It was much easier to blame human error and psychological collapse.

The families believed the official version because they needed someone to blame, and I was the only available target.

Owen's mother had screamed at me over the telephone before hanging up. Aiden's sister had threatened to press for charges. Martin's father had sent letters through his solicitor. They all wanted justice for their loved ones, and I was the closest thing they had to a responsible party.

I did not blame them. If someone had told me Daniel had vanished in impossible circumstances, I would have demanded answers as well. Real answers, not stories about a shape-shifting creature and a riddle hidden inside a cottage that had never existed.

But I knew what I had experienced in that clearing. The weight of the flare in my hand. The way its direct light stripped the stolen faces from the creature. The absolute silence after its central darkness split and dispersed.

At first I had believed the flare destroyed it. Yet there had been no remains, nothing I could show anyone, and now Daniel's voice was calling to me in Manchester. The thing might have survived. It might have re-formed. Or it might somehow have attached itself to me.

Those memories remained sharp while everything else from that night blurred together.

The warning had been the key. Tucked beneath the small oak document chest on the bench inside the cottage entrance, it had read: "When shadows move and stolen voices call, trust no face within these walls. Let direct light expose the lie. What hides in darkness cannot endure the blaze."

Someone else had encountered the creature and left instructions for those who came after. Someone who understood that direct light could expose its mimicry and drive back the darkness beneath its borrowed faces.

I had understood the warning just in time to save myself, but too late to save my trainees. That knowledge rested in my chest like a physical weight, heavier than any guilt over wrong turns or failures of leadership. I had failed them not through inexperience, but through ignorance of what we were truly facing.

Now I was the only living person who knew the truth about that part of Grizedale Forest. The only one who understood that the creature might still be out there, hunting and waiting for another group of walkers to stumble into its territory. And I was powerless to do anything about it.

Who would believe me?

Forestry England officials, who had already dismissed my account? Cumbria Constabulary, whose investigation was effectively closed? Other outdoor instructors, who would regard me as a danger to the whole profession?

I had tried to describe some of the details to Dr Clarke during our early sessions, but she immediately redirected the conversation towards trauma processing and coping strategies.

The medical profession had tidy categories for everything I described. Auditory hallucinations. Visual distortions. Dissociative episodes. Survivor's guilt manifesting as an elaborate fantasy. Every detail of my experience could be explained away without confronting the central question of what had happened to five healthy adults in familiar woodland.

So I played along.

I took the medication, attended therapy and nodded when Dr Clarke discussed recovery times and adjustment disorders. I allowed everyone to believe that I was a traumatised outdoor instructor gradually recovering from a tragic incident, because the alternative was worse.

The alternative was to be considered either completely delusional or criminally responsible. Those were the only choices available to someone who insisted upon an impossible truth: compulsory psychiatric intervention or renewed criminal scrutiny, both ending in the destruction of whatever freedom and credibility I had left.

Better to be the broken survivor than the delusional suspect.

But late at night, when Daniel's voice drifted up from the empty streets, I could not maintain the pretence, even to myself.

I knew what I had heard in the forest. I knew what had taken my trainees, and I knew it might still be out there, patient and hungry, waiting for another chance to feed.

Other walkers would eventually find that place. Someone would take a wrong turn, follow a path absent from the Forestry England maps or wander away from an established route. They would see the low stone-and-timber cottage with its slate roof and narrow veranda, though no foundations, debris, damaged vegetation or GPS-consistent evidence remained after my escape.

They would investigate because curiosity so often overcame caution. Inside, they would find the oak document chest and the cryptic warning beneath it. They would probably dismiss both as a prank or some forgotten historical curiosity.

Then they would hear the screech.

I would know nothing until their families began demanding answers that nobody could provide. Another tragic disappearance. Another conclusion citing exposure, terrain hazards and poor preparation. Another file set aside with reasonable explanations that avoided the unreasonable truth.

Perhaps the creature had hunted there for decades. Perhaps longer. How many people had been reported missing over the years? How many unexplained disappearances had been attributed to natural causes? How many families had been told that their loved ones had simply become lost and died from exposure?

I opened the laptop and searched online news archives for missing-person cases connected to Grizedale Forest and the surrounding Lake District.

The results made my stomach tighten. There were numerous reports stretching back thirty years: lone walkers who had never returned, groups whose routes ended without explanation, search operations that recovered abandoned equipment but no bodies.

All of them had been explained through the familiar risks of the outdoors. People became lost. People made mistakes. People underestimated changing weather, difficult ground and the dangers of travelling beyond managed paths. Reasonable explanations that satisfied everyone except the families left behind.

Yet as I scrolled through them, I thought I could see a pattern. If the creature had been feeding for years, it had taken people singly or in small groups, never often enough in one place to attract the wrong kind of attention. It was intelligent enough to space out its hunting and patient enough to wait for the right opportunities.

And it might still be alive.

I closed the laptop and returned to the window. The street below remained empty except for several parked cars and an occasional pedestrian hurrying past. Ordinary city sounds filtered through the glass. Ordinary life continued all around me.

But I felt the weight of all those unresolved cases and all the families who had never received real answers. I might be the only person who understood what had happened to at least some of them, and I could not tell them without destroying my own life.

The voice came again, softer this time but unmistakably Daniel's.

"I'm scared about this route, Callum. It's more technical than anything I've done before. I could really use a spotter."

I gripped the window frame and forced myself to breathe slowly.

Just another hallucination. Just echoes of trauma moving through a damaged mind. Nothing more than electrical misfires in a brain that had witnessed too much and could not process it properly.

But Daniel sounded real and immediate, exactly like the brother I had failed to save three years earlier and failed to save again when the creature borrowed his voice as bait.

I checked every light in the flat once more, making certain each bulb shone brightly against the darkness pressing at the windows. Then I settled into the chair beside my desk and prepared to wait for dawn, as I had learnt to do whenever the voices returned.

Somewhere, perhaps still in Grizedale Forest, the creature might be waiting too, patient and hungry, ready for the next group of walkers to stumble into its trap.

Or perhaps it had survived the flare, re-formed and followed me to Manchester.

I was the only person alive who knew enough to recognise it, trapped in a city flat with the knowledge that no one would ever believe me.
