The Cold Store Monitor

I was 22, living in Sheffield and working two part-time jobs that together gave me just enough to keep my head above water and send GBP 240 to my mum every month. Tesco Extra on Abbeydale Road gave me four shifts a week, stocking shelves and unloading deliveries. At weekends, I drove delivery rounds for a commercial printer in Attercliffe. The money was tight, but it was steady.

Steady was what mattered when my mum, Janet Mercer, was three months behind on the gas bill and winter was not finished yet. I knew the exact balance because I was the one who rang her energy supplier when she could not face doing it herself. GBP 38 overdue in January, then GBP 91 in February, then GBP 164. By the time March came round, I was looking at that number the way you look at a leak in the ceiling, knowing it will only get worse.

The launderette on London Road had a cork noticeboard outside, the sort of community board where people pinned adverts for car-boot sales, guitar lessons and rooms to rent. On Tuesday 10 March 2026, I stopped there between shifts to get a coffee from the petrol station next door. That was when I saw the card.

It was white card, handwritten and pinned to the bottom-right corner of the board with a red drawing pin. The blue ballpoint writing was formed in neat block capitals.

FACILITY MONITOR VALE CROWN COLD STORAGE ROOK FELL NIGHTS - CASH IN HAND CALL TO START

Below that was a telephone number. There was no application form and no explanation of what the job involved.

I stood there with the coffee cooling in my hand and read it twice to make sure I had not missed anything. Facility monitor could mean almost anything. Nights meant I could keep my shifts at Tesco. Cash in hand meant immediate payment, with no payslip or delay, and Rook Fell was roughly an hour north of Sheffield. Close enough to make the drive worthwhile if the pay was decent.

I took out my mobile and rang the number from the car park. It rang twice before a man answered.

"Graham Vickers."

His voice was low and dry, the sort of voice that did not waste words.

"I'm ringing about the facility monitor job," I said. "The card on London Road."

"Can you drive to Rook Fell?"

"Yes."

"Can you start tonight?"

I hesitated, but only for a second. My next Tesco shift was not until Thursday, and the printer did not need me until Saturday. I needed the money more than I needed to know what I was walking into.

"Yes."

"GBP 165 in cash for one night. Meet me at the site at 23:00. I'll text you the address."

"What is the job?"

"Everything you need will be on the card when you get here. See you tonight."

He ended the call before I could ask anything else. I stood staring at my mobile, the dead line buzzing in my ear. The whole conversation had lasted perhaps sixty seconds.

GBP 165 for one night.

I had just agreed to earn more per hour than I made stocking shelves, and I did not even know what the work was. I did not care. The figure was GBP 165, and Janet owed GBP 164.

That was all the arithmetic I needed.

When I got home, I rang her. She answered on the third ring.

"Hello, love."

"Hi, Mum. I've picked up a one-night warehouse job tonight. I'll ring you in the morning."

There was a pause. Not a long one, just enough for me to know she was deciding whether to ask.

"A warehouse job," she said. "That sounds good. Are you eating before you go?"

"Yes, I will."

"Good. Drive carefully."

"I will."

She hung up. I set the mobile on the kitchen worktop and looked at the time. It was a little after noon. I had ten hours before I needed to leave.

I did not eat.

At 21:30, I got into my car and took the M1 north, followed by the A61 and then an unclassified road across the moors towards Rook Fell. The village was hardly more than a cluster of stone houses, a petrol station and a village Post Office that appeared to close at 16:00. The unsigned single-track access road branching from the A61 was just a gap between the trees and a strip of worn tarmac that looked as though it had not been resurfaced in twenty years.

I followed it for about a mile and a half until the trees gave way to a flat stretch of cleared ground and the building came into view. It was low, broad, concrete and windowless. There was no sign and no light except a single floodlight above the loading bay at the far end. It was the sort of building you could pass a hundred times without noticing because there was nothing about it that wanted to be noticed.

I pulled into the gravel car park and switched off the engine. Graham Vickers was already there, standing by the loading bay with his hands in his coat pockets, as though he had been waiting for some time without growing impatient.

He led me inside without ceremony. He moved at a steady pace, never hurrying but never pausing, and I fell into step behind him.

The entrance opened into a central passage that stretched deep into the building, and the cold struck me at once. It was not the sharp bite of winter air. It was heavier than that, something that settled in my chest and made me breathe shallowly.

Five corridors branched from the passage, each lined from floor to ceiling with steel racking. The pallets stored there were hidden beneath opaque black covers secured with clear industrial film. I could not make out any shapes, labels or other clue to what the place held.

Graham did not slow as we passed them. He pointed nothing out, and I had no chance to stop and look more closely. The building felt larger inside than it had from the car park. Its corridors seemed to extend farther than the outer walls should have allowed.

At the centre of the building, Graham stopped beside a glass-walled monitoring booth. It was roughly 2.5 metres square, with clear walls on three sides and a single door facing the main passage. Inside stood a metal folding chair, a portable electric heater and a desk with a monitor divided into four CCTV feeds.

"You'll be in here," Graham said.

He opened the door and stepped inside. I followed. The heater was already running, filling the silence with a low electrical hum. The monitor cycled soundlessly through its four views: Corridor 1, Corridor 2, Corridor 3 and Corridor 4.

Every feed showed the same basic scene. Empty aisles, steel racking and overhead lights throwing long shadows across the concrete floor.

"The CCTV cameras cover the first four corridors," Graham said, gesturing towards the screen. "The loading-bay controls are here."

He pointed to a panel on the wall beside the monitor. It had a numerical keypad and a status display that read SEALED in green letters. Beneath it were rows of buttons I did not recognise.

"Cold Room 5 is at the end of the passage," he added, without turning to look towards it. "You won't need to go in there."

I looked past him through the glass wall. A heavy insulated door stood at the far end, the sort fitted to a walk-in freezer. Its paint had faded, but I could still read the stencilled words COLD ROOM 5. A padlock hung through its handle.

Graham took a laminated card from his coat pocket and placed it beside the monitor. It was white card sealed in clear plastic, with black lettering across the top.

NIGHT MONITOR GUIDELINES - READ FIRST

"Everything you need is there," he said.

I looked from the card to him.

"What am I supposed to-"

But Graham was already heading for the door. He stepped into the passage, his boots echoing softly on the concrete, and walked towards the loading bay without looking back.

A moment later, I heard the heavy clunk of the loading-bay seal engaging. Then there was silence.

I was alone.

For a moment I stood listening to the electric heater and the faint buzz of the overhead lights. The building was too quiet, the sort of quiet that made me conscious of every breath.

I sat in the folding chair and picked up the laminated card.

RULE 1: AT 01:00, A MAN IN AN ORANGE SAFETY HELMET WILL KNOCK ON THE MONITORING-BOOTH WINDOW AND SAY THAT HE NEEDS TO CLOCK OUT. WITHOUT OPENING THE DOOR, TELL HIM THROUGH THE GLASS THAT NO ONE MAY LEAVE UNTIL THE LOADING BAY SEALS AT 04:00. DO NOT LET HIM IN.

I read it twice. The specificity of it felt wrong: the orange safety helmet, the exact time, the exact words I was meant to use. It was not written like guidance. It was written like a script.

I continued.

RULE 2: SOUNDS FROM COLD ROOM 5 BETWEEN 02:00 AND 03:00 ARE A NORMAL PART OF FACILITY OPERATIONS. THE PADLOCK MUST NOT BE OPENED FOR ANY REASON DURING THIS PERIOD.

RULE 3: IF THE CORRIDOR 3 CAMERA FEED SHOWS A FIGURE MATCHING YOUR DESCRIPTION, STAND COMPLETELY STILL AND DO NOT TAKE YOUR EYES OFF THE SCREEN UNTIL THE FIGURE IS NO LONGER VISIBLE.

I stopped and read that one again.

A figure matching my description.

I looked at the monitor. The Corridor 3 feed occupied the lower-left corner. It showed an empty aisle under steady overhead lights. The racking did not move. There was nothing there.

I returned to the card.

RULE 4: THE LOADING BAY WILL ATTEMPT TO UNSEAL BETWEEN 03:00 AND 04:00. DO NOT ALLOW IT. THE PANEL OVERRIDE CODE IS 2746.

I put the card down. My hands were steady, but my thoughts were not.

The rules made no sense. A man in an orange safety helmet. A figure matching my description. A loading bay trying to open by itself.

I looked at the monitor again. Four feeds. Four empty corridors. The heater hummed, the lights buzzed and the building remained silent.

I picked up the card and read Rule 3 once more to be certain I had understood it. I had.

The Corridor 3 feed remained empty. The lights were on. The racking was still.

I sat back with the laminated card in my hand and stared at the screen.

I had been watching the cameras for nearly two hours when the knock came, and I was not ready for it.

The blow against the glass made me jerk upright. The folding chair scraped backwards with a metallic shriek that made me wince. I caught the edge of the desk to steady myself.

A man stood outside the booth wearing an orange safety helmet.

He looked ordinary, perhaps in his mid-fifties. He had a lined face that suggested years of outdoor work, tired eyes and the weathered appearance I had seen on countless loading bays and warehouse floors. He could have been anyone. He could have been my Uncle Peter. He could have been the man who delivered pallets to the rear of Tesco on Tuesdays.

He raised a hand in a small wave, smiled and spoke through the glass.

"My shift ended an hour ago. I just need to clock out and get home."

His voice was muffled but clear, pleasant rather than angry.

I checked the clock on the monitor.

00:40.

Twenty minutes early.

The card had said 01:00. It had said that a man in an orange safety helmet would knock at 01:00, not 00:40. I had spent the last hour rehearsing the required words in my head so that I would not stumble over them. Now he was here, and I had to say something.

I cleared my throat.

"No one may leave until the loading bay seals at 04:00," I said through the glass, keeping my voice level.

The man nodded slowly, as if he had heard this before and was not surprised. As if someone had told him exactly the same thing the previous week, and the week before that.

"It's doing it again, then," he said.

It was not a question. Just a statement.

Then he sat on the floor outside the booth, rested his back against the glass and settled down to wait.

I stood watching him. He did not appear upset. He did not take out a mobile or check a watch. He simply placed his hands in his lap and stared at the opposite wall.

I lowered myself into the folding chair, slowly this time, and switched my attention to Camera 2. The man appeared in the feed, sitting exactly where I could see him through the glass. The camera caught him in profile.

He did not move. He did not shift his weight, adjust his helmet or perform any of the small, restless movements people make when they have to wait.

I checked the other feeds. Corridor 1 was empty. Corridor 3 was empty. Corridor 4 showed the same black-covered pallets I had watched all night, the clear industrial film reflecting the lights in dull streaks.

I returned to Camera 2. The man still had not moved.

Five minutes passed. Then ten.

I waited for him to stand, knock again or begin pacing. People did not sit that still. They fidgeted. They checked their pockets. They sighed.

This man did none of those things.

Fifteen minutes.

I glanced at the laminated card. Rule 1 did not say what would happen after I refused him entry. It only said to give him the message and not let him inside. It did not say that he would sit down and wait. It did not say that he would accept the refusal without an argument.

Twenty minutes.

At exactly 01:00, the man stood.

He did not look back at the booth or say anything. He rose, brushed the dust from his work trousers and began walking towards the far end of Corridor 2.

I leant towards the screen. The corridor ended at a concrete wall. There was no door and no visible seam, only flat grey concrete beneath a single light.

The man reached the wall and continued walking. He did not slow or raise his hands to protect himself. He walked straight into the concrete as though it were not there.

Then he was gone.

Not through a door. Through the wall.

I stared at the feed. The corridor was empty. The wall was solid. The light above it flickered once and steadied.

I switched to Camera 1. Empty.

Camera 3. Empty.

Camera 4 showed the passage near Cold Room 5. Nothing moved.

I returned to Camera 2. It was still empty.

Only then did I realise that my hands were shaking. I pressed them flat against the desk until they stopped.

The card had said that a man in an orange safety helmet would knock at 01:00. It had said to tell him he could not leave until 04:00. It had not said that he would arrive early and stand at the appointed time. It had not said that he would walk through a wall. It had not said where he would go, what he was, or whether I should be concerned that he might still be somewhere inside the building.

I took a pen from the pocket of my navy work coat and uncapped it. My hand still trembled, but I managed to write across the back of my left hand in small, cramped letters.

01:00 - WALL C2

I replaced the cap and put the pen down.

The depot was quiet. The refrigeration system maintained the same low, steady hum it had made since I arrived. The monitor cycled through the feeds in silence.

I sat in the folding chair with the note on my hand, staring at the empty Corridor 2 feed and telling myself the next two hours would be fine.

I did not believe it.

At 02:05, sounds began inside Cold Room 5.

They were separate from the refrigeration hum, which had long since faded into the background. These were footsteps: slow, deliberate steps pacing the length of the room in a measured pattern.

I leant forwards and watched the Camera 4 feed. The corridor was empty. The padlock remained through the Cold Room 5 handle, exactly where it had been when Graham showed me the building. The faded stencilling was barely visible beneath the overhead light.

The footsteps continued, steady and unhurried. They reached me through the monitor speaker with a muffled quality, as if they had travelled through layers of insulation and concrete, but they were clear enough.

Someone was walking in there.

I checked the card although I had already memorised Rule 2.

Sounds from Cold Room 5 between 02:00 and 03:00 were a normal part of facility operations. The padlock must not be opened for any reason.

Normal operations.

I looked from the empty corridor to the locked door. The footsteps continued back and forth. Without intending to, I counted their rhythm.

Eight paces one way. A pause. Eight paces back.

Again and again.

I did not move towards the door.

Seventeen minutes passed like that. I watched the padlock, listened to the footsteps and kept my hands flat on the desk. The heater buzzed beside my leg, with the refrigeration hum beneath everything else.

At 02:22, the footsteps stopped.

The silence that followed was worse.

I held my breath, waiting for them to resume. They did not.

Then something struck the inside of the door.

It was not a knock. It was an impact, as though something large and heavy had been hurled against the metal from the other side. The door flexed outwards in its frame.

I watched it happen on Camera 4: the whole door bowing, its frame straining against the concrete, the padlock pulled taut but holding.

The door settled back into place.

I stared at the screen. My hands remained flat on the desk. I did not move towards it.

The silence stretched for another minute, then two. The refrigeration hum filled the space where the footsteps had been.

At 02:41, a voice came from inside Cold Room 5.

At first it was muffled and indistinct. I leant towards the monitor speaker, trying to understand it. The sound was low and distorted, like someone speaking through layers of cloth or frost-coated steel.

Then it said my name.

"Daniel Mercer."

Not Daniel alone. Not Mercer alone. Both names, full and clear, with the particular weight Janet put on Mercer whenever she said my full name. She had pronounced it that way since I was a child, usually when I was in trouble or when she needed me to listen properly. Nobody else ever got it quite right. Strangers said it flatly, as if reading it from a list or a name badge. Janet made it sound as though the two names belonged together and always had.

I sat back.

Graham had never asked my name. Not during the telephone call and not during the walk-through. There had been no application form. Nobody at Vale Crown Cold Storage had been given my details.

Nobody here knew me at all.

I stared at Camera 4. The padlock was still closed. The corridor was empty and the door was motionless.

I did not go to it.

The voice did not speak again. I remained in the folding chair with Camera 4 filling the monitor, watching the locked door and waiting.

At 03:00, the activity inside Cold Room 5 ceased. The far end of the building fell quiet for the first time since 02:05. The silence was not merely the steady refrigeration hum. It was the absence of something that had been there and had now decided to stop.

At 03:07, the loading-bay panel lit by itself.

Amber warning lights flashed in sequence across the top row. The status display changed from SEALED to UNSEALING, the letters bright against the black plastic casing.

I crossed to the panel and entered 2746.

The amber lights went out. The display returned to SEALED.

I released a breath I had not realised I was holding.

Behind me, all four CCTV feeds dissolved into static.

Grey and white snow filled the monitor. Then Camera 3 returned by itself, clear and at normal resolution.

Corridor 3 appeared beneath its flat overhead lighting. Under the third light, with its back to the camera, stood a figure dressed in my exact clothes.

A navy work coat with a torn right cuff. Black jeans. Grey trainers with a split near the left toe.

Rule 3 came back to me word for word.

Stand completely still and do not take your eyes off the screen until the figure is no longer visible.

I stood before the monitor and watched.

The figure did not move. Four minutes passed, perhaps longer. I counted seconds in my head at first, then lost track and simply kept my gaze fixed on the screen.

The corridor remained silent. The figure's back was towards the camera. I could see the tear in its right cuff, in exactly the same place where my coat had caught on a loading-bay latch two months earlier.

Then it turned.

Its face was mine.

Not similar. Not close. Mine exactly. The same broad nose, the same jaw and the same dark eyes. But it was smiling at something above and behind the camera rather than looking into the lens.

The smile was already there when its face came into view, as though it had been smiling all along and I had only just been allowed to see it.

The figure reached up, grasped the light fitting above it and tilted it down until it pointed directly into the Camera 3 lens.

The feed turned white.

I did not move. I kept my eyes on the screen while the glare filled it and washed out every detail.

Then Camera 3 returned.

The corridor was empty.

The other three feeds came back at the same moment, each showing the empty racking and flat overhead light I had watched for hours.

I let out another held breath.

Behind me, the monitoring-booth door handle turned.

I did not open the door. I grabbed the folding chair and jammed it beneath the handle, wedging its legs against the floor. The chair held.

I turned back to the monitor. Camera 1 covered the outside of the booth door. The figure from Corridor 3 was standing there, facing the camera. It still wore my face. It was still smiling.

It tried the handle once, casually, as if checking whether the door was locked rather than attempting to force it.

The figure cupped its hands around its mouth and spoke through the door.

I heard my own voice. Not an imitation. My exact pitch and rhythm, the words shaped precisely as I would have shaped them.

"Graham told me to come in from the cold."

I took the fire extinguisher from its bracket beside the loading-bay panel. It was the only heavy object in the booth. I stood between the door and the controls, gripping it in both hands.

The panel lit again.

This time it was not a simple unsealing warning. It had begun a full opening cycle. The display counted down from eighty seconds. The override could cancel the attempt, but only before the cycle completed.

I made the decision in less than two seconds.

I lunged for the panel and hammered 2746 into the keypad.

The cycle cancelled with nine seconds remaining.

The panel went dark.

I turned back to Camera 1. The space outside the door was empty.

I checked all four feeds in sequence. Nothing was visible in any corridor. The racking stood undisturbed beneath the lights.

I did not sit down. I remained in the centre of the booth with the fire extinguisher in my hands and watched the cameras until 04:00.

At exactly 04:00, the loading bay sealed with a deep mechanical thud, like a vault door closing. The control panel went dark by itself. All four feeds shifted simultaneously to wider angles, revealing an empty building. The corridors extended beneath the flat lights, the racking untouched.

I sat on the floor with the fire extinguisher across my lap.

At 04:15, Graham entered through a side door I had not been shown, a plain metal door in the east wall set inside a three-metre-deep recess. I heard it open and listened to his steps crossing the concrete.

He appeared in the monitoring-booth doorway and looked down at me.

"How did it go?"

I told him about the man in the orange safety helmet walking through the wall. I told him about the voice in Cold Room 5, the figure on Camera 3 and the loading-bay overrides. I gave him each event in the order it had happened, without commentary.

Graham listened and nodded at every item. He did not appear surprised. He asked only one question.

"Did you open Cold Room 5?"

"No."

"Good."

He handed me a white envelope. I could feel the flat weight of the notes inside. GBP 165.

Then he turned and left through the same side door. His footsteps receded across the concrete, the door closed, and shortly afterwards I heard a car start outside and drive away.

I stood alone in the monitoring booth with the envelope in my hand. The fire extinguisher remained on the floor where I had put it.

I drove south towards Sheffield with both hands on the wheel and the envelope on the passenger seat where I could see it. The road was empty. The sky had begun to pale at the edges, that flat grey light before sunrise, and I kept my speed steady because driving faster would have left more of my mind free to consider what I had just escaped.

A twenty-four-hour transport cafe outside Chesterfield appeared when I needed it most. Its bright windows stood out against the morning gloom, with two lorries and a car parked outside.

I left my car beneath a broken light at the far edge of the car park.

Inside, the air smelled of disinfectant and frying oil. A cafe server behind the counter looked up, nodded and returned to filling the napkin holders. I chose a corner table near the back, where I could see both the room and the door.

She brought me a menu.

"Just strong tea, please."

She returned with a mug and a small metal pot. I wrapped both hands around the mug and felt the heat through the china, but I did not drink.

The tea sat there while I stared at the table and tried to steady my breathing.

The thing in Corridor 3 had worn my navy work coat, including the torn right cuff. It had worn black jeans and grey trainers with the split beside the left toe. I had bought those trainers six months earlier from a British Heart Foundation charity shop in Rotherham, and the split had already been there.

Nobody else would know that. Nobody else would have any reason to.

I looked at my reflection in the window beside the table. The same face. The same coat. The glass was too dark for me to see my eyes clearly, only the shape of my head and shoulders.

I turned away.

After a while, the server returned and asked whether I wanted anything else. I said no, and she took the pot away. The tea had stopped steaming.

I took out my mobile and rang Mum. She answered on the second ring.

"Daniel Mercer."

Her voice was steady, as it always was, and she pronounced my full name in that familiar childhood way. But she had answered too quickly. She had been awake, waiting.

"Hi," I said. "I've just finished. I wanted to let you know."

"You sound tired."

"I'm fine. It went all right."

There was a pause. I heard her breathing and the small sounds of her moving around the kitchen. She was probably making tea. She always did that when she could not sleep.

"I've found better-paid work," I said. "Warehouse monitoring. Cash in hand. Your gas arrears are covered."

The pause was longer this time.

"Daniel, love, you don't have to do that."

"They're covered. I've already put the money aside."

She did not argue. She never did about money. She released a breath I had not known she was holding and said she was glad.

"Get some sleep. You sound as though you need it."

"I will."

"I mean it."

"I know."

We said goodbye. The screen went dark in my hand, and I placed the mobile beside the untouched tea.

That was when I noticed my right palm.

Four parallel lines ran from the base of my fingers towards the heel of my hand. They were dark red, nearly purple at the edges, and the skin had risen into welts. The fire extinguisher's valve handle had bitten deeper than I realised.

I could still feel its weight and the cold metal pressing into my palm while I stood in the monitoring booth watching the cameras.

I flexed my hand. The welts stretched, sending a dull ache beneath the bruising. I studied them for a moment, then lowered my hand into my lap where I could not see it.

The server came past once more and asked if the tea had been all right. I told her it had. When I left, I put a GBP 4 cash tip on the table.

The next few days passed. I worked my shifts at Tesco, stocking shelves and unloading pallets at the back. The commercial printer reduced my Saturday round to four hours instead of the full weekend, which left me GBP 50 down each week.

The GBP 165 from Rook Fell went straight to Janet's GBP 164 gas arrears. What remained from my ordinary wages disappeared into deductions, food and an electricity notice that had sat on my kitchen worktop for three weeks.

By Sunday 15 March 2026, the envelope was empty and I was back where I had started.

That was when Graham texted me.

The message arrived just after noon. I was sitting at my kitchen table with a plate of beans on toast I had not finished, scrolling through job adverts that all wanted experience I did not possess or availability I could not offer.

DIFFERENT SITE AVAILABLE THURSDAY 19 MARCH. SAME WORK. BIGGER BUILDING. GBP 330 CASH WHILE WE ARE SHORT-STAFFED.

I put the mobile down and stared at it.

GBP 330. Two weeks of food, another month of Mum's gas and enough to get ahead for once instead of merely staying level.

I picked up the mobile and put it down again.

I had known the money would win. That was not the question. The question was what the thing in Corridor 3 had been trying to tell me by wearing my face. Whether it had been warning me to stay away or testing whether I would.

I did not know. I still do not.

Twenty minutes passed. The beans on toast went cold. Outside, a car alarm began and then stopped.

I looked at the mobile again, unlocked it and typed YES before I could think any harder.

Graham's reply arrived in less than a minute.

VALE CROWN COLD STORAGE. OUTSIDE EAST MARSTON, LEICESTERSHIRE. ABOUT FORTY MINUTES EAST OF LEICESTER VIA THE A47. ARRIVE 21:55. NEW CARD ON ARRIVAL.

I set the mobile on the table with Graham's message still displayed. The four welts remained clearly visible across my right palm.

On Thursday 19 March 2026, I reached the East Marston facility at 21:55, five minutes early as Graham had instructed. I pulled into a gravel car park beside a chain-link fence running the length of the building.

The place was at least twice the size of the Rook Fell depot. It was a long concrete structure with several loading bays along one side and a flat roof extending into the darkness. A sign beside the entrance showed eight corridors and two monitoring booths. At the rear, separated from the main storage floor by a heavy steel door, stood a section visible through the nearest reinforced window. The word PROCESSING had been stencilled across it in faded red paint.

Graham was waiting by the main entrance with his hands in his coat pockets. He held the same posture he had at Rook Fell, as though he had been there for a long time and did not mind waiting.

He unlocked the entrance and took me as far as the first monitoring booth. It was larger than the one at Rook Fell. The main door opened onto the storage floor, while a second metal door stood in the rear wall. It had no sign or window. I assumed it led to a cupboard or narrow service passage.

"There are two monitoring booths," Graham said. "Eight corridors, but your physical inspection covers Corridors 1 to 5 only. The cameras cover the rest. If Corridor 6 loops, you do not enter it."

He took a laminated card from his pocket and handed it to me. It was longer than the Rook Fell card, printed on both sides, the plastic warm from inside his coat.

"Processing is not your zone tonight," he said.

I nodded.

"Understood."

He looked at me for a second, then turned and walked back to his grey Ford Ranger. I noticed the Leicestershire registration as he crossed the car park. He had been there for less than four minutes. The engine started, the headlights swept across the fence and then he was gone.

I sat in my car with the laminated card in my lap and read it before going inside.

There were nine rules this time.

RULE 1: COMPLETE ONE PHYSICAL INSPECTION OF CORRIDORS 1 TO 5 BEFORE 23:00. DO NOT ENTER CORRIDORS 6, 7 OR 8 DURING THE WALK-DOWN.

RULE 2: IF A CAMERA FEED LOOPS, SOMETHING IS PRESENT IN THAT CORRIDOR WHICH WILL NOT APPEAR ON CAMERA. RECORD THE CORRIDOR NUMBER. DO NOT ENTER IT.

RULE 3: IF CORRIDOR 6 LOOPS, CLOSE IT THROUGH THE INTERCOM LOCKDOWN SYSTEM AND KEEP IT CLOSED FOR THE REMAINDER OF THE SHIFT.

RULE 4: IF A VOICE ON THE INTERCOM ASKS TO BE RELEASED FROM A LOCKED CORRIDOR, DO NOT ANSWER IT.

RULE 5: IF ANY LOADING-BAY SEAL ATTEMPTS TO OPEN BEFORE 04:00, CANCEL THE CYCLE. THE OVERRIDE CODE IS 2746.

RULE 6: IF A MAN IN AN ORANGE SAFETY HELMET APPEARS AT EITHER MONITORING BOOTH, DO NOT OPEN THE DOOR. IF MORE THAN ONE APPEARS, CHANGE CAMERA CYCLES ONCE AND ONLY ONCE.

I recognised the rhythm of the instructions. They had the same structure as the Rook Fell card, only longer and more elaborate.

I turned it over.

RULE 7: DO NOT ENTER PROCESSING UNDER ANY CIRCUMSTANCES.

RULE 8: IF PROCESSING ENTERS YOUR SPACE, TURN TOWARDS THE NEAREST EXIT AND WALK TO IT WITHOUT STOPPING. DO NOT TURN AROUND.

I read Rule 9 three times.

RULE 9: IF THE NUMBER OF VISIBLE FIGURES IN ANY CORRIDOR INCREASES BY MORE THAN TWO BETWEEN CAMERA CYCLES, DO NOT ATTEMPT TO COUNT THEM AGAIN.

I folded the card, slipped it into the pocket of my navy work coat and got out of the car.

The Vale Crown building outside East Marston was colder than the one at Rook Fell. It was not merely the refrigeration hum, though that was the same low mechanical drone I had heard before. The air itself seemed to have weight. It held a stillness that did not feel as if it came from any ventilation system, and the corridors stretched farther than they should have done.

Steel shelving lined them, half-stocked with pallets hidden beneath opaque black covers and bound in clear industrial film. There was no way to see what was underneath. Everything was too clean and too empty, as though the whole depot had been scrubbed and then abandoned.

I found my monitoring booth and settled in. This one had two folding chairs, a larger control panel and eight CCTV feeds divided between two screens. There was also the second exit Graham Vickers had pointed out during his walkthrough. I had assumed it led to a cupboard or a narrow service passage and had given it little thought.

I took out the laminated card and taped it to the edge of the desk, where I could read the nine rules without lowering my head.

At 01:15 on 20 March, I carried out a standard camera check. I cycled through all eight feeds one at a time and noted the timestamp on each. Camera 6 was repeating the same four seconds of empty corridor. Its timestamp was frozen at 01:09. The overhead light remained steady. The shelving did not move.

The card had warned me about this. A looping feed meant that something was present in the corridor but could not be seen on camera. I was not to enter that corridor. I was to press the intercom button for Corridor 6 and say that the aisle was closed.

I pressed the button.

"The aisle is closed," I said.

My voice sounded steady and flat through the speaker.

I waited.

Four seconds passed. Then I heard the mechanical click of the talk button engaging at the other end.

Someone, or something, had pressed the intercom button in Corridor 6, but it did not speak. The line remained open. Through the speaker came the faint hum of the refrigeration system, the same low drone that filled the building, but nothing else.

There was no breathing. No movement.

On Camera 6, the same four seconds continued to repeat beneath the frozen timestamp.

I marked Corridor 6 as closed on my clipboard and did not look at that feed again.

At 02:30, I began the required physical inspection of Corridors 1 to 5. The card said that walk-downs were mandatory every two hours. Corridor 6 was excluded now that its feed was looping, and I had no intention of going anywhere near it.

I took the torch from the pocket of my navy work coat, even though the overhead lights were still on, and started with Corridor 1.

It was empty. Normal.

The covered pallets stood on steel shelving. The concrete floor was spotless, and the air was cold enough for my breath to show.

Corridor 2 was the same.

So was Corridor 3.

Corridor 4 looked normal until I reached the far end.

The shelving stopped at a short dead end that did not appear on the map Graham had given me. Beyond it was a three-metre-deep recess containing nothing but bare concrete walls and open floor.

Three men stood inside it with their backs to me.

All three wore orange safety helmets. All three were motionless.

The posture of the nearest man, the set of his shoulders and the angle of his helmet were exactly the same as those of the man at Rook Fell. The man who had first knocked twenty minutes early and then risen at exactly 01:00 before walking through a wall.

I stopped.

None of the men turned. None reacted to the sound of my footsteps ending.

They simply faced the concrete wall as though they had been standing there for years and would remain there whether anyone watched them or not.

I did not speak. I turned and walked back the way I had come, moving at the same slow pace I had used on the way in.

I did not run. I kept my breathing controlled and my footsteps even. I walked all the way back to the monitoring booth without looking over my shoulder.

Once inside, I checked Camera 4.

The recess was empty.

I stared at the feed for a long time. Then I opened the previous ten minutes of camera history and moved through the recording frame by frame.

The three figures appeared for two consecutive frames.

In both, they had turned to face the camera. Their orange safety helmets were gone, and their faces were clearly visible.

They were identical.

It was the same lined, tired-looking face on all three men, perhaps in its fifties. I did not recognise it, but I could see every feature clearly.

I exported one of the frames as a JPEG to a USB stick using the booth's export port. Then I removed the stick and put it into the pocket of my work coat.

I did not look at the image again.

At 03:10, the power failed.

The darkness was instant and complete.

I switched on the torch I had brought from my car, the one I had carried everywhere since Rook Fell, and aimed it at the floor in front of me.

The card gave clear instructions for a power failure. Stay in the monitoring booth. Do not open either door. Count aloud to one hundred.

I opened my mouth to begin.

Before I could say the first number, I heard the steel door to Processing open at the back of the building.

It did not close. The noise did not come from the corridor outside my booth. It came from deeper within the depot: the heavy clunk of a steel door moving on industrial hinges.

The sound travelled through the darkness like something heavy falling.

Then came footsteps.

There were many sets of them. They were not running. They moved at a measured, methodical pace, like workers carrying out a walk-down and checking the aisles one by one.

I began counting.

"One."

My voice was low but steady. I kept the torch aimed at the floor.

"Two. Three. Four."

The footsteps moved through Corridor 7.

Then Corridor 8.

Then Corridor 5, which was closer.

Then Corridor 3, which ran directly beside my booth.

"Twenty-six. Twenty-seven. Twenty-eight."

One set of footsteps stopped outside the main door of the monitoring booth.

I kept counting.

I could hear nothing from whatever stood there. No breathing. No movement. No shift of weight. There was only the absence of footsteps where, a moment earlier, footsteps had been.

"Fifty-three. Fifty-four. Fifty-five."

The other sets continued moving. They entered Corridor 2 and then Corridor 1, spreading through the building as though searching for something.

"Eighty-one. Eighty-two. Eighty-three."

The presence outside my door did not move.

"Ninety-seven. Ninety-eight. Ninety-nine. One hundred."

The power returned.

I checked the camera covering the corridor outside the booth. It was empty.

I cycled through all eight feeds. Every visible corridor was empty.

Then I looked at the door handle.

There was frost on the outer side of it. I could see it through the small wired-glass window in the door: a white smear in the precise shape of a palm and four fingers, as though someone with an impossibly cold hand had pressed it against the metal from outside.

At 03:45, fifteen minutes before the loading bay seals were scheduled to engage, I noticed that the monitoring booth's second exit was standing open.

I had not opened it. I had not been near it since starting the shift.

Through the doorway, where I had expected a cupboard or service passage, I could see directly into Processing.

Red emergency lights illuminated a long room of stainless-steel tables. Floor drains ran from one end to the other. Personal belongings had been arranged in careful rows across the tables: purses, mobile phones, key rings, watches and dozens of pairs of shoes, each pair placed neatly together.

At the far end of the room, the Processing loading bay door was opening by itself.

Beyond it, in the exterior bay, stood the three men from Corridor 4. Their orange safety helmets were back on their heads. They stood motionless, facing the doorway where I was standing.

All three were looking at me.

Processing had entered my monitored space.

Rule 8.

I turned towards the main exit. I did not look back into Processing.

I walked through the main corridor towards the exterior door at a steady pace. I did not run. I did not stop.

Behind me, I heard the Processing loading bay seal at 04:00. The noise was slow and soft, like an enormous breath being released.

I did not turn around.

I passed through the main door, crossed the car park and got into my car. I locked every door.

I did not start the engine. I sat with my hands on the steering wheel and the USB stick in my coat pocket, watching the facility's entrance through the windscreen as I waited for Graham.

He arrived shortly after 04:00. From inside my locked car, with the engine still off, I watched his grey Ford Ranger enter the car park. It had a Leicestershire registration.

Graham parked, got out and walked into the building without looking in my direction.

I checked the time on my mobile.

He remained inside for twelve minutes.

When he emerged, he came straight to my window. I lowered it far enough to speak to him. He handed me an envelope containing GBP 330 in cash, as promised.

"Processing finished early tonight," he said. "That's unusual. Take next week off."

His tone was the same as it had been at Rook Fell: purely informational, with no trace of surprise.

"What was on those tables in Processing?" I asked.

Graham looked at me for so long that I thought he might not answer.

"Property belonging to guests who didn't need it any more," he said.

"Who were the guests?"

"The ones who aren't on the card."

He returned to his Ford Ranger and drove away towards the A47. I watched his rear lights until they vanished.

Then I began the journey north-west towards Sheffield.

I did not stop at a cafe. I did not telephone my mum. I drove for nearly two hours in silence, the envelope resting on the passenger seat and my hands clenched around the steering wheel.

The sun was rising by the time I reached home.

I parked outside my block of flats and remained in the car for a while. The street was empty. The sky was pale, and its colour looked wrong somehow.

Perhaps I was only tired.

I got out, went upstairs and entered my flat. Then I removed the USB stick from my coat pocket and plugged it into my laptop.

The drive mounted.

It contained a single file.

It was not the frame I had exported. My file had been a JPEG, and this was also a JPEG, but the filename was different: a long string of numbers I did not recognise, followed by 2026-03-10, the date of my first shift at Rook Fell.

I opened it.

It was a photograph taken inside the Rook Fell monitoring station.

I could see the CCTV monitor on the desk, the loading bay control panel and the portable heater in the corner. In the folding chair, head tipped back and eyes closed, was me.

I was asleep.

The timestamp embedded in the photograph's metadata read 02:17 on 11 March 2026.

I had not been asleep at 02:17 that morning.

At 02:05, the sounds from Cold Room 5 had already begun. I had been watching its camera feed and staring at the visibly closed padlock while something inside struck the door and spoke in my mum's voice. Janet Mercer had always said my full name in a particular way when I was a child, with the slight pause between Daniel and Mercer that meant I was in trouble. The voice from the cold room had copied it perfectly.

I had not taken my eyes off that screen until the disturbance ended at 03:00. I remembered watching continuously.

There had been no moment when I was asleep.

I checked the file properties.

Its creation date was 7 March 2026, three days before I saw the handwritten advert pinned to the launderette noticeboard on London Road. Three days before I telephoned the number. Three days before I had ever heard of Vale Crown Cold Storage, Rook Fell or Graham Vickers.

I stared at the screen for a long time.

The photograph did not change. I remained in the chair with my head tipped back and my eyes closed. The timestamp stayed at 02:17 on 11 March 2026.

I closed the laptop.

Then I looked at my right hand.

The four pressure welts across my palm, matching the valve handle of the fire extinguisher I had gripped during the first shift, had grown darker. Their centres were almost black. They no longer hurt. They simply remained on my skin, as though they had always been there.

I sat at my kitchen table with the closed laptop in front of me and my right hand resting in my lap. The four dark marks lay across my palm.

I did not open the file again.
