The Watcher from the Asylum

I clicked through another sequence of footage from the abandoned pottery works, cutting out the moment when my torch beam had caught a pair of fox cubs and I had jumped like an idiot. Five hours of editing for what would become a 14-minute video. The routine had become automatic over the past few months. Explore, film, edit, upload, repeat.

Solo work moved more slowly than it had when I had a partner, but it felt safer. The notification from my mobile broke my concentration. Callum Price's name appeared on the screen, and I hesitated before answering. Cal and I had not spoken for roughly ten weeks, not since our last argument about the direction of the channel.

Six months earlier, we had been inseparable. Callum Price and Elliot Ward, urban-exploration partners who had built a decent following by documenting abandoned places across the country. Our chemistry on camera had been natural, the sort of back-and-forth that made viewers feel as though they were tagging along with friends rather than watching strangers perform. Everything had changed after Liverpool.

We had spent a long weekend exploring a derelict hospital complex outside the city, documenting the decay of what had once been a cutting-edge medical facility. The buildings were vast, spread across several acres, with multiple wings and underground tunnels connecting different sections. On our final day there, we discovered that parts of the complex were not as abandoned as we had thought. Evidence of recent occupation lay scattered throughout the basement levels: sleeping bags, food containers, drug paraphernalia and makeshift altars constructed from stolen medical equipment.

The squatters had been using the hospital for activities that went far beyond seeking shelter. We found rooms where symbols had been painted on the walls in what looked like blood, animal bones arranged in deliberate patterns, and spaces that resembled religious shrines. The smell of rotting organic matter was overwhelming in certain sections. In several rooms, we discovered dead animals positioned in ways that suggested ritual use rather than natural death.

Cal had wanted to film everything.

He argued that documenting the squatters' activities would make compelling content, and that our subscribers would appreciate the raw authenticity of discovering something genuinely disturbing. I insisted that we leave at once and report what we had found to the local authorities. The disagreement escalated into our first proper row, with Cal accusing me of being too cautious and me questioning his judgement about what counted as responsible exploration. We left the Liverpool hospital without filming the occupied areas, but the experience exposed a fundamental difference in our approaches.

Cal saw the illegal activity and potential danger as selling points that would increase our subscriber count and viewing figures. I saw them as warning signs that we needed to be more careful about the locations we chose and the risks we were willing to take.

Over the following months, Cal pushed for increasingly ambitious explorations. He suggested investigating places with known security problems, buildings where other explorers had been arrested, and sites with documented hazards that responsible explorers avoided.

When I insisted on sticking to safer, well-researched locations, Cal accused me of losing my edge and becoming boring. The breaking point came when he began going on solo explorations without telling me. He started posting content under his own name, featuring places that made me nervous even when I was only watching the footage: abandoned mine shafts with unstable ceilings, derelict industrial buildings with obvious structural damage, and facilities where he had clearly trespassed on actively monitored property.

His comment sections filled with viewers expressing concern for his safety, but Cal seemed energised by the attention and continued pushing the boundaries. Our partnership officially ended after a particularly reckless video in which he explored an abandoned chemical works with obvious environmental hazards, wearing inadequate protective equipment and ignoring several warnings about contaminated areas. I contacted him privately to voice my concerns. He responded by accusing me of jealousy and suggesting that I was trying to sabotage his growing subscriber base.

Since then, I had concentrated on rebuilding the channel as a solo operation, returning to the careful, research-heavy approach that had drawn me to urban exploration in the first place. My subscriber count had fallen significantly without Cal's dynamic personality, but the viewers who remained seemed to appreciate the more thoughtful, educational content I had been producing.

Now his name was flashing on the screen of my mobile, and I could not think of any good reason why he would be ringing after ten weeks of silence. I answered on the fourth ring.

"Elliot. Oh God, Elliot, please."

Cal's voice was barely recognisable. The confident, sometimes cocky tone I had grown used to during our months of partnership had been replaced by something broken and desperate.

Sobs interrupted his words, and his breathing came in ragged gasps that suggested either injury or complete panic.

"Cal? What's wrong? Where are you?"

"I can't... I messed up, Elliot. I messed up so badly. You have to help me. Please. I know we haven't been speaking, but I don't have anyone else to call."

The words came in a rush, overlapping and barely coherent. Between the crying and what sounded like chattering teeth, I could make out only fragments of what he was trying to say. Trapped. They hurt me. Can't walk.

"Cal, slow down. Tell me where you are. Are you injured?"

"I'm sending you a pin. It's in the north-west Highlands, near the head of a sea loch. Please come and get me. Please, Elliot. I'm sorry about everything. I should have listened to you. I should have..."

The line went quiet apart from muffled noises that might have been Cal trying to pull himself together. I moved the mobile away from my ear and saw that he had sent a location pin and nothing else. It marked a place in the remote north-west Scottish Highlands, an exhausting overnight drive from my flat in Bristol.

"Cal? Cal, are you still there?"

"Just come, all right? Do not ring 999. Do not call the police. Don't contact anyone else. Just come and get me. Something happened here, and I can't explain it over the phone. I need you to trust me one more time."

The call ended abruptly, leaving me staring at the pin on my screen. It placed him deep in the Highlands, far from any main road, village or landmark I recognised. Whatever had happened, Cal was alone in a place that would take considerable effort to reach. His emotional state suggested something far more serious than the usual urban-exploration mishaps we had dealt with in the past.

I looked back at my computer, where the pottery-works footage remained paused halfway through the edit. The familiar rhythm of solo work suddenly felt trivial beside the desperation I had heard in Cal's voice. Whatever our differences, whatever arguments had driven us apart, they did not matter when someone rang for help in that state of terror.

I saved the editing project and closed the laptop.

My emergency kit was already packed in the hall cupboard: first-aid supplies, rope, torches, spare batteries and water. It was the equipment I carried on every exploration, refined over months of experience to deal with the situations we had encountered in abandoned buildings. I downloaded the route and surrounding maps for offline use, then grabbed my car keys from the kitchen worktop.

Cal had sounded genuinely afraid, more frightened than I had ever heard him during our partnership. Whatever he had got himself into in the Highlands, he needed help. I could not ignore that call.

The northbound M5 and then the M6 stretched ahead through the darkness. For mile after mile, my headlights and those of the occasional lorry were the only lights on the carriageway. I had already been driving for hours since leaving Bristol, and the route still showed a long journey ahead before I reached Cal's pin. The digital clock on the dashboard read 02:47, and I was beginning to feel the strain of pushing through the middle of the night.

My mobile sat in the cup holder beside me. I had tried ringing Cal every half-hour since setting off. Each attempt went directly to voicemail, giving me the same automated message I had already heard a dozen times. The silence from his end made the initial call seem stranger still.

I kept replaying that broken, desperate voice asking for help before the line cut off. I could not imagine what might have produced that level of terror in someone who had spent months chasing increasingly dangerous thrills.

At a late-night motorway services, I stopped for coffee, forced down a sandwich and filled the petrol tank. I knew there would be few opportunities to refuel once I entered the Highlands, and the remoteness of the pin had been obvious even on the map. The stop cost me time, but arriving without enough petrol to get Cal back to civilisation would help neither of us.

Beyond the motorway, towns became scarcer and the darkness deeper. I joined the A82 and continued north, the road winding between lochs and rising ground. Later, the route took me onto the A87 and farther into the Highlands. Clusters of distant lights marked the occasional settlement, but long stretches passed with no sign of habitation at all.

Petrol stations and places to stop disappeared. I was left with the hum of the engine, the steady rhythm of tyres on tarmac and the rattle of my emergency kit whenever the road surface became uneven. The first-aid supplies, rope and spare torches offered some comfort, although I could not shake the feeling that whatever had happened to Cal might require more help than my basic equipment could provide.

The way he had specifically told me not to contact the police suggested something complicated, probably illegal, but the panic in his voice had been too real to dismiss.

At around 04:00, the satnav directed me away from the better road and onto a remote Highland A-road that twisted through darker, emptier country. The surface was cracked and patched after years of repeated winter frosts. My headlights caught reflective eyes beside the road. Red deer, most likely, though they slipped back among the bracken and birch too quickly for me to be certain.

The mobile signal became unreliable and then vanished altogether, leaving me dependent on the mapping I had downloaded before leaving Bristol. The pin Cal had sent lay near the head of a sparsely inhabited sea loch, far from any settlement or landmark I recognised. I tried to imagine what sort of exploration could have drawn him to such an isolated place, especially when travelling alone after our partnership had ended.

The A-road gave way to a narrow B-road marked by a weathered sign I nearly missed in the headlights. The tarmac became rougher, with broken sections patched by loose stone that struck the underside of the car. Birch branches brushed the roof and windows as the road narrowed, forcing me to slow down to avoid overhanging limbs and sudden potholes.

The B-road eventually became an unclassified single-track road, with passing places appearing at irregular intervals. There was no other traffic to use them. Low cloud pressed over the hills, and black water showed between the trees whenever the road curved close to the loch.

By 05:30, the offline route led me onto what could barely be called a road at all. A deeply rutted forestry track stretched ahead through Scots pine, birch and dense ranks of commercial conifers. The trees stood so closely together that my headlights penetrated only a short distance into the plantation.

Deep wheel ruts had carved channels through the mud and gravel. I had to steer carefully to avoid grounding the car or damaging the suspension. Running water had scoured out sections of the track, creating obstacles that forced me to creep forwards while testing their depth with the front wheels. Fallen branches blocked the way in several places, and each time I had to get out and drag them aside before continuing.

The forest around me was completely silent except for the engine and the crunch of gravel beneath the tyres. I stopped twice to check the offline map and make sure I was still following the correct route. Cal's pin seemed impossibly remote, miles from the nearest village or properly surfaced road. Whatever had drawn him there must have seemed important enough to justify the journey, but I could not imagine any abandoned building worth exploring in such isolation.

The track twisted through the hills for another hour, climbing through bends that made me nervous about the return trip. Thanks to the stop at the motorway services, the fuel gauge remained comfortably above half. I calculated that I had more than enough petrol to reach the site and return to an A-road, provided the track did not become impassable.

The thought of becoming stranded while Cal lay injured somewhere ahead kept me moving despite the worsening conditions.

As dawn filtered through the tree cover, the forest emerged in grey morning light. Mature Scots pines rose among birch and commercial conifers. Moss covered fallen trunks and outcrops of rock, while bracken and undergrowth crowded the spaces between them. Away from the track, crossing the ground on foot would have been slow and exhausting.

The forestry track finally opened into a clearing as full daylight reached the forest floor. I rolled forwards, my headlights illuminating what lay ahead, and stopped when I saw the structure at the end of my journey.

The building was enormous, far larger than I had expected from Cal's sparse description. Brick walls rose three storeys high, with a central frontage roughly 60 metres wide. Its architecture was institutional, built for function rather than beauty, and its rows of windows had either been boarded with weathered plywood or left as empty frames after the glass had long since broken away.

Much of the brickwork showed serious deterioration. Mortar had crumbled from the joints, and water damage stained the walls in long, dark streaks. Ivy, moss and saplings were reclaiming parts of the structure, creeping up the walls and through broken windows. The roof sagged in several places. Elsewhere, sections had collapsed altogether, exposing the interior to the elements.

The clearing contained the scattered remains of what had once been a functioning psychiatric hospital, built to serve an isolated regional community. Rusted medical equipment lay overturned in the long grass: wheelchairs with missing wheels, hospital beds reduced to twisted metal frames, and what appeared to be the remains of an ambulance, its rear doors hanging open and every window gone.

A chain-link fence had once enclosed the grounds, but most of it had fallen or been bent back by years of neglect. Weeds and young trees had broken through the cracks in the old car park, and the original drive was barely visible beneath fallen leaves and debris.

The whole scene suggested a place abandoned for decades and left to decay in the Highland wilderness, where no one considered it worth maintaining or demolishing.

I parked near what appeared to be the main entrance and switched off the engine. The sudden silence felt heavy after the long drive, broken only by birds beginning their morning calls in the surrounding trees.

I took a torch and the first-aid kit from the passenger seat. My mobile was fully charged, but there was still no signal. I slipped it into my pocket, shouldered my emergency rucksack and looked towards the building.

Its broken windows resembled empty eye sockets in the morning light. Somewhere inside that decaying psychiatric hospital, Cal was waiting for help, assuming he was still alive after whatever had put such fear into his voice.

I braced myself for what I might find as I approached the entrance, hoping the eleven-and-a-half-hour journey through the night would not end with the discovery that I had arrived too late.

My boots crunched through debris scattered across what had once been a paved walkway. The heavy wooden entrance doors stood partly open, leaving a gap just wide enough for someone to squeeze through sideways. Fresh scratches scarred the metal around the lock, marks left by prying tools rather than weather.

The smell reached me before I stepped inside: a thick mixture of mould, decay and something else I could not identify.

Water damage had turned the main corridor into an obstacle course of fallen plaster and warped floorboards. Stains ran down the walls where decades of rain had entered through the failing roof, creating abstract patterns in the pale morning light filtering through broken windows.

"Cal!"

My voice bounced along the empty corridors, the echo carrying deeper into the building than I expected.

"Cal, it's Elliot. Where are you?"

Nothing answered except my own breathing and the distant drip of water somewhere in the building's depths.

I switched on my torch and began searching the ground floor, checking each room as I reached it. Long corridors were lined with small patient rooms, most still containing rusted bed frames and pieces of medical equipment abandoned when the hospital closed. Cupboard doors hung from broken hinges, revealing empty shelves where medicines and supplies had once been stored. Wheelchairs stood in corners, their vinyl seats cracked and split after years of damp and changing temperatures.

The patient rooms were mostly identical: small spaces with a single window, a bed frame and built-in cupboards stripped of anything valuable decades ago. I called Cal's name into each one. My torch beam revealed peeling paint, mould and floors littered with debris from the ceilings above.

Twenty minutes into the search, I found what I had been looking for in what appeared to have been a communal room.

Cal's camera bag lay on the floor beside an overturned table, its contents partly spilled across the warped lino. His tripod was nearby, one leg bent at an angle that suggested it had been dropped rather than set down. His jacket was draped over the back of a chair pushed against the wall, and his water bottle lay beside it, still half full.

The scattered belongings made my stomach tighten. Cal was careful with his equipment, almost obsessive about keeping his camera gear organised and protected. Seeing it abandoned like this confirmed that something had gone badly wrong during his exploration, something serious enough to make him leave behind equipment he could not afford to replace.

I picked up the camera bag and checked inside. His main camera was missing, along with the spare batteries and memory cards he always carried. Either he had taken them when whatever happened began, or someone else had removed them from the bag.

The damaged tripod would have been impossible for him to carry if he was as badly injured as the telephone call suggested. The missing camera, however, raised the possibility that he had continued documenting whatever he had found.

"Cal!" I shouted, louder this time. "I've found your stuff. Where are you?"

The building swallowed my voice without returning a sound.

The silence felt heavier than before, as though the structure absorbed noise instead of reflecting it. I continued deeper into the old hospital, checking each room methodically and calling for my friend.

The building extended much farther back than I had realised from outside. Several wings branched from the main corridor, and staircases led both up to the first floor and down towards what appeared to be a basement. Searching the entire hospital would take hours, even if I could safely enter every area that had not deteriorated beyond repair.

As I moved farther in, the condition of the floors became increasingly worrying. Water had rotted through several boards completely, creating gaps that exposed the darkness below. I tested every step, watching for soft patches that might collapse under my weight. In one corridor, an entire section of flooring had fallen away, forcing me to edge along the wall around a hole that dropped into the basement.

The smell intensified the deeper I went. What I had first taken for mould and structural decay now carried undertones of animal waste and rotting organic matter, odours we had encountered at other abandoned sites. It was not coming from the fabric of the building. This was something else, something suggesting recent biological activity in a place that should have stood empty for decades.

I paused at the junction of two corridors and tried to decide where to search next.

The eastern wing continued straight ahead, disappearing into darkness beyond the reach of my torch. To my left, another passage led towards larger rooms that might once have been offices or treatment areas. Behind me waited the staircase to the basement, its concrete steps descending into complete darkness.

Cal could have been anywhere in that maze of decaying rooms and unstable floors. His injuries might have left him unable to answer my calls even if he could hear me. The thought of him lying somewhere inside, unconscious or too weak to respond, drove me to move faster through the search.

I chose the eastern wing first, stepping around gaps in the floor while sweeping my torch across every room. The patient rooms looked identical to those I had already searched, but the smell was unmistakably stronger in that direction. Something in the eastern wing was producing the organic stench, and I began to suspect that whatever Cal had discovered was connected to its source.

My torch crossed the first patient room, revealing the same crumbling walls and rusted bed frames found throughout the hospital. As I moved deeper along the corridor, however, the smell that had troubled me since entering became impossible to ignore. The reek of decay was coming from ahead and growing stronger with every step.

The third room stopped me completely.

Dark stains covered sections of the walls in patterns too deliberate to be water damage or natural decay. I stepped closer and aimed the torch directly at them, trying to understand what I was seeing.

The stains formed symbols: rough but intentional designs painted across the peeling wallpaper. The colour was wrong for paint, too dark and brown, with the rusty appearance of old blood.

I took out my mobile and photographed the symbols, making sure the details were clear. Cal would need the evidence later, assuming I could discover what had happened to him and who was responsible.

The symbols covered three walls of the small room. Every design was different, but they shared angular elements suggesting they belonged to a larger pattern or system.

The next room contained more of the same markings, but these were fresher. The dark substance had not dried completely, and the odour was stronger there, mingling the metallic scent of blood with something that turned my stomach. I moved through quickly, documenting everything with my mobile while trying not to breathe too deeply.

Four more patient rooms revealed similar evidence of recent activity. Someone had been using that wing of the hospital for purposes that had nothing to do with exploration or documentation.

The symbols varied in complexity, but all appeared to have been painted with the same dark substance. In one room, geometric patterns surrounded a central circle. In another, the markings resembled letters from an alphabet I did not recognise.

The corridor opened into a larger space that must have served as the hospital's main dining hall when it was in use.

What I found there made me understand why Cal's voice had carried such terror during the call.

The room was enormous, with a high ceiling and large windows that would once have filled it with daylight during meals. Now the windows were boarded or broken, leaving the space dim except for my torch beam. Long metal tables that had once held catering equipment had been arranged in a rough circle around the centre of the room.

What covered them made my hands shake as I tried to take photographs.

Dead animals had been arranged in deliberate patterns across every surface. Rabbits, cats, several small terriers, crows and other birds lay in circular formations that plainly followed an organised plan. The stench of rotting flesh was overwhelming. I had to breathe through my mouth as I documented the scene.

Some of the animals had clearly been dead for weeks, their bodies reduced to dried skin and exposed bone. Others were more recent, with their fur or feathers still intact but their eyes clouded by decay. Every table held a different arrangement.

One displayed rabbits in a perfect circle, their heads pointing towards a mound of bird feathers at the centre. Another held cats arranged in a spiral around small animal bones that had been cleaned and sorted by size. The precision made it clear that these were neither natural deaths nor the work of scavengers. Someone had killed the animals and placed them there deliberately.

Makeshift altars had been built from stolen medical equipment. Hospital bed frames were stacked into raised platforms and draped with dark fabric that looked expensive against the crumbling surroundings. Candles had burnt on the improvised surfaces, leaving thick wax that had melted and hardened into strange forms. Someone appeared to have shaped the wax while it was soft, creating patterns matching the symbols on the walls.

Along the eastern wall, hooded robes hung from metal hooks driven into the brickwork. They were charcoal in colour and made from heavy fabric, intended for ceremonies rather than ordinary wear. I counted seven robes. Whatever had taken place there involved seven people working together.

I moved cautiously around the room, photographing everything without disturbing the arrangements. The evidence needed to remain exactly as I found it, both for Cal's safety and for any later investigation. Each table, altar and painted symbol offered part of a story that made me increasingly afraid of what he had stumbled into.

Something at the centre of the dining hall dominated the entire space.

It was a figure about 2.4 metres tall, carved from polished black slate veined with pale mineral streaks. The workmanship was sophisticated, far beyond amateur effort. Someone had invested serious time and money in creating it.

The figure was humanoid, but wrong in proportions that made it uncomfortable to look at directly. Its limbs were unnaturally elongated. Its arms hung below the point where a person's knees would have been, while its legs appeared too thin to support its torso. Long fingers extended like claws rather than human hands.

The head was oversized in relation to the body. Its surface suggested a face but lacked the details that would make it recognisably human. The features looked unfinished or ill-formed, as if the sculptor had tried to reproduce something that did not properly fit the structure of a human skull.

More dead animals surrounded the base, arranged in concentric circles that formed a broad border around the sculpture. These remains were older than those on the tables, reduced to bone and dried skin that appeared to have been deliberately maintained rather than left to decay naturally. Someone had tended the display for months, perhaps years, adding new specimens while preserving the old.

I circled the figure slowly, taking photographs from every angle. The polished slate must have required considerable effort to shape and transport to such a remote place. Symbols had been carved into its base, similar to those painted on the walls but more intricate and permanent.

The entire installation suggested commitment and resources far beyond casual occult experimentation.

As I documented the room, the pieces of Cal's situation began to fit together. He had discovered people using the Highland hospital for organised rites that plainly mattered a great deal to them. The time and labour invested in the displays, the expensive materials, the careful arrangement of the animal remains and the seven ceremonial robes all proved that this was not the work of vandals or bored teenagers.

These people took their activities seriously. They had the dedication and resources to maintain the site over a long period. Cal's intrusion into whatever they had been doing would have been regarded as a serious violation by people who had invested so much in their work.

The terror in his voice now made perfect sense.

He had not found mere graffiti or minor evidence of trespass. He had walked into the centre of something these people considered sacred, or at least important enough to defend with violence.

I finished photographing the slate figure and the surrounding arrangements, ensuring I had clear images of every detail that might matter later. The evidence on my mobile could be crucial to understanding what Cal had experienced and to any Police Scotland investigation that followed.

More immediately, it confirmed that my friend was in grave danger from people willing to devote considerable time and money to acts most of society would find deeply disturbing.

There was no sign of Cal in the dining hall, but what he had discovered explained his desperate call. I needed to find him before the people responsible returned and discovered that someone else had been photographing their work.

I found a staircase near the eastern corner of the building, behind a door bearing the faded words AUTHORISED PERSONNEL ONLY. The concrete steps felt solid beneath my boots, which was a relief after the rotten floorboards above. The temperature fell as I descended, and my breath began to mist in the cold air trapped underground.

My torch revealed concrete walls bearing the same water damage as the upper floors, although the damp had caused different problems there. White mineral deposits ran from joints in the ceiling where groundwater had seeped through, and patches of black mould covered surfaces that never received daylight.

The painted symbols continued below ground, covering large sections of the basement walls in the same dark substance that looked far too much like dried blood.

Several small rooms opened from a central corridor. They had probably served as storage areas or plant rooms during the hospital's working years. My torch showed clear signs of recent human occupation in each of them.

Sleeping bags lay neatly rolled in corners, still bearing depressions where people had recently lain. Empty food containers and water bottles were stacked against the walls. Battery-powered camping lanterns had been positioned throughout the basement, providing light without access to the mains electricity.

Someone had been living there regularly, not merely visiting for ceremonies. The organised sleeping arrangements suggested that several people had used the basement as a base while conducting whatever rites they had established in the dining hall above.

Fresh clothing hung from makeshift lines strung between metal support beams. Basic toiletries stood on improvised shelves made from medical equipment carried down from the upper floors.

I called Cal's name again, but the sound seemed muffled, absorbed by the concrete walls and low ceiling. The basement extended farther than I had expected, with the corridor continuing beyond the first rooms into darkness my torch could not fully penetrate.

Then I heard it.

A faint moan came from the far end of the corridor.

It was weak and irregular, but unmistakably human. It came from somewhere beyond the rooms I had already searched.

I hurried towards it, sweeping my torch over the floor to avoid obstacles and calling out to let Cal know I was coming.

The moaning stopped when I shouted his name, then began again a few seconds later, as though whoever made it could not control the sound or was too badly injured to answer properly.

The corridor ended at a heavy wooden door reinforced with metal brackets and additional fittings. Its original lock had been replaced with something far more substantial. Fresh scratches around the frame showed where tools had been used to install the new security measures.

This was not a storage room. Someone had converted it into a place where a person could be held against their will.

I tried the handle and found the door unlocked. The metal hinges protested as I pushed it open.

The smell of blood and human waste struck me at once, mingling with the basement damp and making me gag. My torch swept across the small room and revealed exactly what I had been searching for.

Cal sat tied to a metal chair at its centre, his arms bound behind his back with rope and his mouth covered by strips of gaffer tape.

The position of his legs made my stomach drop.

Both were bent at angles that were completely wrong, injuries caused by deliberate violence rather than an accident. His jeans were torn and stained with blood where bone had broken through the skin. The swelling around the fractures was severe enough to stretch the fabric tight.

His face was covered in bruises and dried blood. One eye had swollen completely shut, and cuts crossed his cheeks where someone had struck him repeatedly. The gaffer tape over his mouth had been loosened recently, perhaps removed to let him eat or drink, but adhesive residue and torn skin showed that it had been there for hours.

Cal's one open eye fixed on me as I entered. Instead of relief, I saw pure terror.

He shook his head frantically and made muffled noises behind the tape, trying to communicate something urgent. When I stepped towards him to remove the restraints, he tried to lean away, as though my arrival had made his situation worse rather than better.

I reached for the tape and peeled it from his mouth as gently as I could. He winced with pain. The moment he was able to speak, words rushed out in a whisper so faint I could barely hear them.

"You have to leave me here. You have to go now, before they come back."

"Cal, I'm getting you out of here. Just let me..."

"No!"

He tried to pull away again. His voice rose into a hoarse whisper that echoed around the little room.

"They're coming back soon. They said they'd be back before noon. If they find you here, they'll kill both of us."

I ignored his protests and began working on the rope around his wrists, cutting through the thick fibres with my pocketknife. Cal kept staring past me at the doorway, his good eye darting back and forth as though he expected someone to appear at any moment.

"How long have you been down here?"

"Since yesterday afternoon. They caught me upstairs, taking pictures of their things. They were furious about the camera."

The rope parted, freeing his wrists, and I moved to examine his legs more closely. The fractures were severe and plainly required urgent treatment in an accident and emergency department. As soon as mobile signal returned, I intended to call an ambulance.

Yet someone had cleaned the wounds and wrapped them in fresh bandages. Whoever had broken Cal's legs had not wanted him to bleed to death. They had intended to keep him alive, at least temporarily.

They wanted him alive, at least for now.

"This is going to hurt, Cal, but I need to move you."

I slipped my arms beneath Callum's shoulders and lifted him from the chair as carefully as I could. The moment his broken legs shifted, he screamed, the sound cutting through the basement like a knife.

The pain was clearly too much. I felt his body stiffen as he fought to remain conscious. His hands seized my shirt with surprising strength for someone who had been tied up for nearly twenty hours, his fingers twisting into the fabric as though he were trying to anchor himself. His breaths came in short, panicked gasps.

"They're going to hear that," he whispered. "They're going to know someone's here."

I adjusted my grip and started towards the door, taking most of his weight while trying not to worsen his injuries. Every step made him gasp or whimper, but he managed to keep quiet enough that we were unlikely to attract attention from outside the building.

The basement corridor seemed much longer on the way back, particularly with Callum's weight dragging at my arms as I picked a route around the scattered equipment and makeshift furnishings. I had to stop twice to rest and adjust my hold. Each pause made him more agitated, and he kept staring into the shadows behind us.

By the time we reached the staircase leading back to the ground floor, we were both exhausted. Callum's pain was worsening, and my arms trembled from the effort of carrying him through the basement. But the concrete steps ahead were our route to freedom, provided we could reach the ground floor without being discovered by whoever had turned the place into their base.

The staircase felt endless. Each step sent a fresh shock through Callum's broken legs, forcing him to bite down on his screams. I had to stop three times to shift my grip as his weight slipped. By the time we reached the top, both of us were drenched in sweat. His uninjured eye kept darting towards the rear of the building, searching the shadows behind us for movement.

Getting through the crumbling corridors required careful navigation around the gaps in the floors and the debris I had memorised during my search. Callum tried to help by pushing against the walls with his hands, taking some of the strain from my arms, but every jolt made him gasp. After the basement's confined spaces, the smell of mould and decay seemed suffocating.

When we finally reached the main entrance, the morning light streaming through the broken windows looked impossibly bright.

Callum squinted against the glare. His swollen face looked worse in natural light. The scratches and bruises covered more of it than I had realised in the basement's gloom, and dried blood had crusted around cuts that needed proper medical treatment.

I helped him through the doorway and across the debris-strewn approach to my car. The passenger door opened with its usual squeak, and I eased him on to the seat as gently as possible.

He immediately gripped the door handle and the edge of the dashboard, his knuckles white and his breathing shallow and rapid.

"We need to go," he said. "We need to go right now."

I closed his door, hurried round to the driver's side and took one last look at the asylum's frontage.

The building looked exactly as it had when I arrived hours earlier. Nothing outside suggested that anything had changed. But knowing what lay within those walls made the structure feel different, as though its blank windows were concealing an awareness of our escape.

The engine started at the first turn. I reversed away from the building, then swung the car towards the forestry track. Callum twisted awkwardly in his seat to look through the rear window. The movement must have been agony with his broken legs, but panic had overwhelmed any concern for the pain.

"Faster," he said. "Please, drive faster."

I pressed harder on the accelerator and guided the car across the clearing and on to the deeply rutted track that had brought me there. Branches scraped along the windows as we passed between Scots pine, birch and dense ranks of commercial conifers, but Callum's attention remained fixed on the mirrors and the view behind us.

The psychiatric hospital vanished behind the trees. His fear did not. If anything, he became more anxious once we were moving, constantly checking the side mirrors and reaching up to alter the rear-view mirror for a better view of the track behind us.

"They could come back at any time," he said. "They said they'd be back before noon."

I glanced at the dashboard clock. It read 10:47. We had some time, assuming his captors kept to their schedule, but his fear was too intense to be explained by people who were still some distance away.

"Cal, we're out. You're safe now. We'll get you to the nearest accident and emergency department. I'll call an ambulance as soon as we have a mobile signal."

He shook his head frantically, wincing as the movement jarred his injuries.

"You don't understand what happened. You don't know what I did."

The forestry track curved through a succession of tight bends, taking us farther from the hospital and closer to the unclassified single-track road that would lead to the B-road and, eventually, a Highland A-road. Every mile should have made Callum feel safer, but he continued to search our surroundings.

I waited until he had grown accustomed to the movement of the car before asking for details. His broken legs and battered face told part of the story, but his behaviour suggested something more complicated than an assault and imprisonment.

"Tell me what happened yesterday. Start at the beginning."

Callum shifted in the passenger seat, trying to find an angle that did not put pressure on his damaged legs. One hand remained locked around the door handle. He paused twice to check the mirrors before he began.

"I got to the building at about 14:00. I wanted to document the whole place before dark, you know? The same routine we used to have."

The track straightened enough for me to maintain a steadier speed while he talked. His voice was hoarse from screaming and dehydration, and I had to listen carefully to catch every word.

"I started on the ground floor and worked through the old patient rooms. Standard stuff. Nothing we hadn't seen at other places. But the basement was different. All those beds, the supplies. Someone was living there regularly."

He shifted again, his good eye moving constantly between the side mirror and the track ahead. Soon we emerged on to the unclassified single-track road, and after several more miles the B-road appeared beyond the trees, marked by the weathered sign I had passed during my approach.

"When I reached that big room upstairs, the old dining hall, that's when everything went wrong."

I steered on to the narrow strip of tarmac. The surface was rough and patched, but after the forestry track it felt almost smooth. Callum stopped speaking long enough to twist round and watch the single-track road disappear behind us.

"There were seven of them in there," he continued. "They were wearing those heavy charcoal robes you saw hanging on the wall. They had candles burning, and they were standing in a circle around that statue."

The description matched what I had photographed on my mobile, but hearing Callum describe the room while the ceremony was actually taking place made it immediate in a way the abandoned objects had not. These were not merely remnants someone had left behind. He had seen the rite in progress.

"They were chanting something. Words I didn't recognise. It might have been another language, or it might just have been sounds they'd invented. I couldn't tell. But they were completely absorbed in it, all of them focused on that thing in the centre."

His fingers tightened around the door handle as we gathered speed on the B-road. The tarmac was cracked and uneven after years of repeated winter frosts, but it felt like a major route compared with the track we had just escaped.

"I should have left at once," he said. "I should have backed away and got out before they noticed me. But I saw something on one of the tables they'd set up, and I made a stupid decision."

I kept my eyes on the road, though I could sense his nervous energy building as he prepared to explain what had provoked the attack.

"There was an ornate silver bell on the table nearest to me. A ritual bell, I suppose. It looked like real silver and expensive work. I thought it might fetch several hundred pounds if I found the right buyer."

His admission surprised me, although it explained the desperation I had heard during his telephone call. Financial trouble was not something he had mentioned while we were working together, but the months since our argument had evidently brought pressures I knew nothing about.

"I've been having money problems," he said. "Gambling, mostly. I got in deeper than I should have. The people I owe aren't patient, and I've been looking for ways to pay them without asking my family for help."

The B-road climbed through folds of bracken-covered hillside towards the A-road. Callum continued to check the mirrors, but as the distance from the hospital increased, his account became more detailed.

"I waited until the ceremony reached some sort of climax, when all seven of them were staring at the statue. Then I tried to take the bell. I thought I could put it in my bag and slip away without anybody noticing."

I could picture him creeping towards the table as the seven robed figures chanted around the polished black slate figure, reaching for the silver bell while their attention remained fixed on its elongated body and oversized, ill-formed head.

"The moment I touched it, one of them turned and saw me. He started shouting. Before I could even think about running, all seven of them had surrounded me."

What followed needed little description. His injuries spoke for themselves, and I watched him relive the pain as he unconsciously touched the swollen side of his face.

"They used lengths of steel conduit from a plant room. They took turns hitting my legs until the bones broke. They said I'd interrupted something sacred and had to be punished for violating their space."

His voice carried a mixture of anger and humiliation. I understood why he had been reluctant to ask for help. Being caught stealing while trespassing was humiliating enough without the added complications of an occult ceremony and deliberate ritual punishment.

"After they broke my legs, they carried me down to the room where you found me. They cleaned the cuts and bandaged me because they meant to keep me alive, at least for a while. They said they'd decide what to do with me when they returned. But they had to leave immediately because something had gone wrong with the ceremony."

That caught my attention. If the seven of them had been frightened enough to abandon their base and flee the building, it suggested consequences beyond trespass and theft.

"What sort of something? What went wrong?"

Callum checked the mirrors again before answering. When he did, his voice had changed. This was no longer merely fear of the people who had beaten him. It was terror of something else entirely.

"I don't know exactly what they were trying to do with that slate figure and all the dead animals. But whatever it was, it worked."

We reached the A-road and turned towards the nearest town. It was hardly civilisation, but the wider tarmac and occasional traffic offered some reassurance. Somewhere ahead there would be mobile signal, an ambulance and a route to accident and emergency.

"After they left, I wasn't alone down there," Callum said. "Something else stayed behind."

His words hung between us as I accelerated on to the A-road. His panic had never been about the seven robed figures returning. It was about whatever they had called during their interrupted ceremony, whatever had remained inside after the human participants fled.

The engine's steady hum and the rhythmic noise of the tyres filled the silence while I tried to absorb what he had said. I wanted to ask for details, but the look on his face told me he was already forcing himself to continue.

"I know how it sounds," he said, barely audible over the road noise. "I know what you're thinking. Pain makes people see things, doesn't it? Trauma causes hallucinations."

I watched the road for signs pointing towards the nearest hospital. Callum needed medical attention more urgently than he needed to persuade me of anything supernatural, but his desperation made it clear that he would not let the subject rest until he had told me everything.

"After they broke my legs and carried me downstairs, I passed out from the pain. When I woke, it was dark outside and the building was completely silent. I thought they'd gone for the night and meant to return in the morning to decide what to do with me."

He shifted in his seat again, searching for a position that did not aggravate his injuries. His hand never left the door handle, and the whiteness of his knuckles showed how hard he was gripping it despite our growing distance from the asylum.

"I was testing the ropes around my wrists, trying to work them loose, when I heard footsteps in the corridor. Heavy steps, but slow, as though whoever was walking had nowhere in particular to be."

The A-road wound along the contours above the sea loch, taking us towards larger roads and, eventually, the long journey south by the A87, A82, M6 and M5. Callum stopped to check the side mirror, a nervous habit he had repeated ever since we left the building.

"The footsteps stopped outside the door. They stopped completely, as if someone were standing there listening. I held my breath and hoped they would think I was still unconscious and move on."

His description formed images I did not want in my mind. The basement room where I had found him was isolated enough that footsteps in the corridor would have been unmistakable to someone tied to a chair inside it.

"But it didn't move on. The door opened very slowly, as if whoever was outside was being careful not to let the hinges make a sound. And what came through wasn't one of the people in the robes."

I glanced at him. His uninjured eye was fixed on something beyond the windscreen, as though he were watching the scene again instead of remembering it. His breathing had become shallow and quick, the same pattern I had noticed when he described the assault.

"It stood a little over 2 metres tall, but it was so thin that it looked as if someone had stretched a person until all the proportions were wrong. Its arms hung below where its knees should have been. Its legs were far too long for the rest of its body."

The being he described echoed the polished black slate figure I had photographed in the dining hall. But Callum was talking about something that had moved, something that had entered the room and observed him.

My rational mind wanted to blame an hallucination brought on by injury, dehydration and shock, yet the precise details suggested either a remarkably vivid imagination or a genuine experience.

"Its face was the worst part. It was elongated like the rest of it, but not in any natural way. The features were in the wrong places. Its eyes were too far apart and too high on its skull."

Callum craned past the headrest to inspect the rear-view mirror. The movement clearly hurt his damaged face, but he did not stop searching the road behind us.

"And its eyes glowed. They weren't reflecting light from somewhere else. They produced their own light. Bright white light that made everything else in the room look darker."

I wanted to interrupt with rational explanations: fever from his injuries, shock after the beating, the mind's habit of imposing a shape on overwhelming experiences. But his terror was too genuine and too exact to dismiss easily.

"It stood in the doorway for perhaps ten minutes. It didn't move or make a sound. It just watched me with those glowing eyes, as if it were studying me or trying to work out what I was."

The A-road descended into a glen where a small settlement was visible ahead, a handful of houses and businesses clustered beside the loch. The sight of ordinary human activity made his account seem even more surreal.

"Then it came into the room and moved closer to my chair. Every step was perfectly silent. There was no sound against the concrete floor. No breathing. Nothing. But I could feel it getting nearer even when I closed my eyes."

His hands shook hard enough to make the door handle rattle. The memory seemed every bit as terrifying as the original experience.

"When it came close, I could smell it. It wasn't decay or death. It was something chemical and wrong, like burning metal mixed with the ozone after a lightning strike."

I found myself checking the mirrors, his nervous habits beginning to infect me. The A-road behind us held ordinary traffic: several cars and a delivery lorry, all keeping a reasonable distance. Nothing looked unusual or threatening.

"It stood beside my chair for hours," Callum said. "I know because I could see a patch of sky through a basement window. I watched it change from darkness to grey morning and then to full daylight, and all that time the thing stood there watching me."

His account fitted the timing of my arrival. If he was telling the truth, the being had been in the basement while I searched the upper floors, perhaps aware of me without choosing to reveal itself.

"It never tried to hurt me. It never moved closer, never touched me. But having those eyes fixed on me for so long was worse than the pain in my legs. It felt as if I were being examined by something that didn't understand what a human being was meant to be."

I wanted to reassure him, to offer an explanation that did not require belief in a summoned entity. Yet the conviction in his voice and the specificity of his account made simple dismissal seem inadequate.

"When I heard you calling my name upstairs, it turned its head towards the ceiling as though it were listening. Then it looked at me once more and walked out. It moved in the same silent way."

That explained why Callum had appeared so terrified when I found him, and why relief had not been his first response to my arrival. If an inhuman thing had watched him for hours, another voice inside the building might have signalled a new danger rather than rescue.

"It went along the corridor, deeper into the basement, where I couldn't see it. But I knew it was still down there while you were cutting the ropes."

I remembered the sections I had not searched properly. Beyond the rooms containing the sleeping arrangements, the corridor had continued into darkness my torch could not entirely penetrate.

"That's why I kept telling you we had to leave at once. It wasn't only because the people in the robes might return. That thing was still somewhere in the building."

His panic during our escape no longer seemed quite so irrational. If he believed an inhuman presence was hiding in the basement, every second we spent within the hospital would have felt borrowed.

"I know you think I'm mad," he said. "I know how it sounds to someone who didn't see it. But whatever those people were attempting with their ceremony, it worked. They brought something into that building, and it's still there."

I wanted to answer with arguments about trauma-induced visions. Extreme pain, dehydration and psychological stress could create astonishingly vivid false memories. But Callum's consistency and the exact nature of his description made outright dismissal feel premature.

"Cal, you've suffered severe trauma. You've been injured, imprisoned and made to fear for your life. The mind can create extremely convincing experiences in those conditions."

He shook his head at once, then winced as the movement pulled at his facial injuries.

"I thought the same at first. I tried to convince myself it wasn't real, that my mind had created something to focus on besides the pain."

He checked the side mirror again. His surveillance of our surroundings grew more frequent even as we put miles between ourselves and the hospital.

"But hallucinations don't cast shadows. They don't have enough weight to make floorboards creak, and they don't leave footprints in dust on a concrete floor."

The evidence he described could have been verified if anyone returned to examine the basement. Footprints in accumulated dust could not be explained by imagination or fever.

"I watched it walk around my chair several times during the night. I saw its shadow cross the walls when it passed between me and the little window. I heard the floor respond to its weight, even though the steps themselves were silent."

His insistence on physical evidence made his account harder to dismiss. Hallucinations did not usually interact with their surroundings in ways that left measurable traces.

"When morning came and there was enough light to see properly, I saw the prints it had left in the dust. They were long and narrow, with what looked like claw marks at the front."

I began glancing into the rear-view mirror more often, influenced by Callum's fear and his detailed recollection. The road behind us still looked normal. Scattered traffic moved at appropriate speeds and distances.

"The thing I can't get out of my head is the way it looked at me," he said. "Not like an animal watching prey, and not like a person trying to understand someone. More like..."

He paused, searching for the right comparison.

"Like a scientist observing a specimen. Clinical and detached, but completely focused."

A chill ran through me despite my efforts to remain sceptical. His terror seemed too sincere to be entirely fabricated, and the precision of his story suggested either an elaborate delusion or a real encounter.

"I think it was trying to understand what I was," he continued. "As if the ceremony had brought it into this world, but it didn't know enough about the place it had entered."

He had plainly spent hours thinking about its behaviour, trying to construct some meaning from what he had endured rather than merely reacting to it.

"Which means it's probably still learning," he said. "Still trying to understand how this world works and what part humans play in it."

The implications were disturbing enough that I did not want to consider them. If something inhuman was learning about human behaviour through observation, there was no way to predict how it might use that knowledge.

I checked the rear-view mirror again.

The A-road stretched behind us in a long, nearly straight line, giving me a clear view of the following traffic. What I saw made my blood turn cold.

A little under half a mile behind the car, in the centre of the road, stood exactly what Callum had described.

It was a little over 2 metres tall, impossibly thin, with elongated limbs and distorted human proportions. Its oversized head was malformed in the same way as the black slate figure in the hospital. Even at that distance, I could see the brilliant white glow of its eyes fixed directly upon our vehicle.

The creature stood perfectly still while motorists unconsciously steered around it without slowing or reacting. They seemed unable to perceive it properly, yet none struck it. Every car altered course just enough to pass on one side or the other, its driver displaying no sign of having noticed anything in the carriageway.

Those glowing eyes remained fixed on us, tracking the car as we travelled down the A-road.

Without saying anything, I pressed harder on the accelerator, desperate to increase the distance before Callum noticed my change in behaviour. The speedometer climbed past 75 mph, recklessly fast for the road, but the figure in the mirror did not seem to grow any smaller.

Callum noticed the speed and twisted in his seat to look through the rear window. The instant he saw what I was seeing, all colour drained from his face.

"It followed us," he whispered. "It actually followed us out of the building."

The creature remained in the road as we sped away. Its body grew smaller with distance but never vanished completely. Cars and lorries continued to steer around the space it occupied without any conscious response, as though their eyes refused to register it even while some deeper instinct guided them clear.

"This is what I was trying to tell you," Callum said, his voice rising with renewed panic. "Whatever they summoned isn't confined to that building. It can go wherever it wants."

I kept my foot down, watching the speed climb towards 80 mph while trying to understand what I could see in the mirror. The rational part of my mind scrabbled for explanations: an optical illusion, a shared hallucination, some distortion in the glass or the air above the road.

But the figure remained visible and sharply defined. Its bright white eyes never left us.

Whatever had watched Callum in the basement had followed us out of the asylum and on to the A-road. Even when we reached the motorway, even when hundreds of miles lay between us and the abandoned hospital, I knew distance and speed would not guarantee safety.

Our escape had solved nothing.

The real danger was only beginning.
