The Service Door

The stairwell had not changed. It was the same narrow climb, with the same scuff marks in the faded burgundy paint where the handrail had rubbed against it for probably twenty years. I still had my council lanyard round my neck because I had come straight from the office, and the hospital bag containing Graham's things caught on my jacket pocket every third step.

The plastic crinkled. I shifted it to my other hand. The flat was above Pritchard's Fish Bar on Barrasford Street. Always had been.

The shop closed at six o'clock, so the smell was strongest around then. Vinegar, frying fat and damp newspaper. It reached me before I got to the landing. The same smell I remembered from when I was eight, nine, ten.

All the way up.

I stopped at the door. Dark red paint, four panels. A crooked enamel number.

47.

I had lived there until I was twenty-one, and I still had to check the number whenever I came back. Habit, probably. Or perhaps I simply did not want to think of the place as mine.

The key was on the ring Graham had been carrying when he collapsed. They had given it to me at the hospital with his wallet, his mobile and half a packet of mints. Everything fitted into the bag. That was it.

More than thirty years working at Newcastle Central Station, and that was what came home.

I unlocked the door and stepped inside. The smell was different there. The fish bar was still underneath it, but now it was layered with old carpet and whatever cleaning spray Graham used.

Something citrusy.

The hall was narrow, and the light switch was exactly where I remembered it, beside the coat hooks. I pressed it.

The bulb came on. The same warm yellow light that made everything look older than it was.

Graham had died four days earlier, in June 2026. He had collapsed during a shift at Newcastle Central Station, right there on the platform. Someone said he had been checking tickets. Then he had simply gone down.

"Didn't get back up."

They called it a cardiac event, which I supposed was the technical term for your heart stopping in the middle of your day.

I was there because the flat was mine now. Not officially, not yet, but his solicitor had rung the following morning and said the will was straightforward. There was no other beneficiary. Just me.

So I had to clear the place, sort through whatever he had left and decide what to do with a one-bedroom flat above a fish bar that smelt of childhood and regret.

I put the hospital bag on the little table by the door. The lanyard came off next. I hung it from the same hook where I used to leave my school bag.

The flat felt smaller than I remembered.

Or perhaps I was simply bigger.

The hall led straight into the sitting room, which was about four metres across and full of Graham's furniture. There was a sofa with wooden arms, a bookcase without many books and an old silver DVD combi television on a stand. Everything was clean.

That was the thing about Graham. He kept everything orderly. No clutter, no mess, only routines.

I went through to the kitchen, a narrow galley with barely enough room to turn round. The worktops were clear apart from a draining rack and a tin that probably held teabags.

I opened the fridge. Milk, butter, a block of cheese, two eggs, jam and a jar of piccalilli. Nothing that would spoil immediately. I would have to deal with it eventually, but not that evening.

The bedroom was next. A single bed against the wall, tightly made. A wardrobe, a chest of drawers and a lamp on the bedside table. Nothing else.

I did not go in. I only looked from the doorway.

The whole place felt more like a work site than a home. Functional. Maintained. Graham had lived there for decades, yet it still looked as if he had only just moved in and had not got round to personalising it.

As I stood there, I kept replaying the same facts. I had ended up in that flat when I was seven because my parents, Stephen Mercer and Caroline Webb, had separated and neither of them could settle where I was meant to live.

They drifted away. Stephen went to Glasgow. Caroline went somewhere I stopped keeping track of. Graham stepped in.

He was Stephen's older brother. Single, steady, with a flat and a set of routines. I supposed that made him the best option.

He raised me with rules. Reliable ones. Eat at six o'clock. Lights out at half past nine. Homework before the telly. Keep your space clean. Lock the door when you leave.

Do not touch the service door.

That was the only rule he ever repeated. I had forgotten about it until I was standing in the hall again, looking at the cupboard.

It was only a cupboard, really. Narrow and built into the wall between the kitchen and sitting room. Graham kept the vacuum cleaner in there, along with cleaning supplies and coats we rarely wore. But at the back, beyond the vacuum, there was another door.

It was small, about a metre and a quarter high, and made of old wood. It looked as if it had been there since the building went up. A padlock held it shut.

I had asked about it once, when I was about nine. Graham had been putting the vacuum cleaner away. I saw the lock and asked what it was for.

"Service access," he said.

He did not look at me. He simply closed the cupboard door.

"To where?"

"Doesn't matter. You don't touch it."

I pushed, because children do.

"But what's it for?"

He turned then. His face had the look it took on when he was serious. Not angry. Just firm.

"That door stays locked, Elliot. Same as the front door. You don't open it. You don't interfere with it. You don't go near it. Understood?"

I nodded.

"Say it."

"I won't touch it."

"Good lad."

That was it. He never brought it up again.

And I never asked. It became part of the flat. A thing that existed. A thing you did not touch.

I stood in the hall now, looking at the cupboard door. It was closed. I could picture the inside. Vacuum cleaner on the left. Coats on the right. The little door at the back, secured with a padlock.

I tried to concentrate on practical matters. I had to clear the flat.

That meant going through drawers, sorting clothes and deciding what to keep, what to give away and what to bin. I had brought a couple of boxes in the car and could fetch more if I needed them.

Start with the kitchen, perhaps. Easier that way. Less personal.

But I kept looking at the cupboard.

It was daft. Just a service door. It probably led to a crawl space or an old maintenance shaft that had not been used in decades. Buildings like this had all sorts of leftover access points from when they were built. Graham had spent his working life at the station and knew the dangers of neglected infrastructure. He would have known to keep something like that locked.

Still.

I opened the cupboard.

The vacuum cleaner was exactly where it had always been. So were the coats.

Beyond them, at the back, stood the little door. Dark, old wood. The padlock was heavy and black, the kind you might put on a shed.

I stared at it for a while. Then I closed the cupboard and returned to the kitchen.

I would start there. Cupboards first. Get the easy work done, then move on to the rest.

But even as I pulled out drawers and checked their contents, I kept thinking about that door. I kept seeing it in my head.

Graham had treated it like the front door. Locked. Protected. Important.

I did not know why that bothered me.

It probably did not matter. I kept working.

I called the locksmith on Tuesday morning. His name was Dean Fletcher. I found him through Newcastle City Council's approved contractor list, which probably said something about how dull my life was. I trusted a spreadsheet to choose someone for me.

He arrived at eleven o'clock wearing a navy fleece and work trousers with about six pockets. He carried a black canvas bag that looked heavy. He was a big man, well over a metre eighty, solidly built, with short sandy hair and stubble that was probably three days old.

He nodded when I opened the door.

"Elliot?"

"Yeah. Thanks for coming out."

"No bother."

That was the extent of our introductions.

He stepped in and set his bag beside the door, taking in the flat with a quick sweep of his eyes. It was not curiosity, only professional assessment.

I had told him on the phone that it was an estate clearance and fairly standard. He did not ask for details, and I did not offer any.

"Right," he said. "What are we opening?"

I showed him the front door first. I explained that Graham had possessed all the keys, but I wanted the locks changed for security anyway, which was true enough.

Dean crouched and inspected the night latch and mortice lock, running his thumb over the keyway.

"Standard fittings. Dead easy."

He glanced up.

"You want the cylinders changed or full replacement?"

"Full replacement."

"Aye, no problem."

He got to work while I stood back, leaning against the wall beside the coat hooks. There was not much for me to do except watch.

He was efficient. He took tools from his bag without looking, removed the old fittings and aligned the new ones. The whole job took about fifteen minutes. He tested each new key twice, handed me a set and put the old locks aside.

"Bedroom door?" he asked.

"Just needs checking. There's no lock on it."

He walked through the flat, examining the other doors anyway. Bathroom, cupboards, all ordinary household fittings.

Then I showed him the cupboard.

I opened it and moved aside so he could see. The vacuum cleaner stood on the left, the coats hung on the right, and the little wooden door waited at the back with its black padlock.

Dean crouched in front of it. He took a head torch from one of his pockets and fastened it round his forehead.

The beam illuminated the door, giving me a better look than I had managed the day before. The wood was old and had been painted over several times.

But the padlock was new.

Not shiny, exactly, but new compared with everything around it. The metal was neither rusted nor badly scratched. The shackle shifted smoothly when Dean tugged it. He made a low sound in his throat.

"That's an Abus 83-series," he said. "Good lock. Recent, too. From the barrel and the batch markings, I'd say it was fitted within roughly the last eighteen months."

I stared at it.

"You're sure?"

"Aye. We sell these at the shop. Someone put this on fairly recently."

He glanced back at me.

"You've got the key?"

I did not answer at once. I stood there looking at the lock while my mind caught up with what he had said.

Eighteen months.

Graham had replaced the padlock within roughly the last eighteen months. Perhaps even more recently.

That meant he had been using the door. Or securing it. Or something.

"Hold on," I said.

I returned to the table beside the front door and picked up the hospital bag. It was still where I had left it the previous day, unopened apart from when I had taken out the key ring.

I searched through it. Wallet, mobile, mints and keys.

The key ring was a plain metal loop, scratched and dull. Four keys hung from it. I recognised three. The front-door key, his work-locker key and one that looked like it belonged to a shed or garage padlock.

The fourth was unfamiliar. Smaller than the rest, it was made of brass, with sharp, clean teeth that had not been worn down. I held it towards the kitchen light and turned it over.

There were no markings.

I carried the ring back to Dean and held it out.

"Try these."

He took it and tested the keys in the padlock. The first two did not fit. The third slid inside but would not turn.

The fourth, the little brass key, went in smoothly and turned with a soft click. The shackle sprang open.

Dean removed the padlock and handed it to me with the key ring.

"There you go. Want me to take the hasp off as well?"

"The what?"

"The metal fitting screwed to the door."

He tapped it with his knuckle.

"Want it removed?"

I looked at the padlock in my hand.

It was heavier than I had expected. The shackle hung open, and the key remained in the barrel. Graham had carried that key with him, on his key ring, until he collapsed on the platform at Newcastle Central Station.

"No," I said. "Leave it."

Dean shrugged and got to his feet, brushing his knees.

"Suit yourself. Anything else?"

"That's it."

We went back to the front door, and I paid him one hundred and eighty pounds in cash. He counted it quickly, folded it into his wallet and gave me a receipt he had already filled in while sitting in his van.

"Cheers," he said. "If you need anything else, the number's on there."

"Thanks."

He picked up his bag and left. I locked the new front-door locks behind him and stood in the hall for a minute, listening to his boots descend the stairs. Then I heard the street door close below.

The flat was quiet.

It had always been quiet. Graham kept it that way. No radio, no television during the day. No clutter to shift and make noise.

But this was different. It was the sort of quiet that made you notice it. That made you conscious of how still everything was.

I walked back to the cupboard.

Its door remained open. The little wooden service door was still at the back, its latch held by the loose hasp now that the padlock had been removed. I could simply pull it open if I wanted.

I did not want to.

I closed the cupboard and went back to the kitchen. I spent the rest of the day sorting through cupboards and packing the things that could go to a charity shop. Crockery, pans, the tea tin.

I worked until seven o'clock. Then I carried three boxes down to the car and loaded them into the boot. I drove them to the charity donation bank beside a Sainsbury's Local and returned.

By the time I reached the flat again, it was nearly nine.

I considered going home. My place was twenty minutes away, a studio flat in Heaton. It was smaller than Graham's, but at least it was mine. I could sleep in my own bed, wake in the morning and come back to finish the clearance.

But I was tired. It was late. And the sofa was there.

I did not enter the bedroom. I had looked inside the day before, and that was enough. The bed was made. The wardrobe was closed. Graham's bedside lamp remained in its place, its cable neatly coiled on the floor.

It felt as if he had only stepped out. As if he might return at any moment and tell me it was lights out at half past nine.

So I stayed on the sofa. I found a spare blanket in the linen cupboard and used my jacket as a pillow. It was not comfortable, but it was adequate.

I had slept in worse places.

I expected to lie awake for a while. My mind did not switch off easily, especially when I was somewhere that was no longer home.

But I was asleep within ten minutes.

I woke to tapping.

Soft. Muffled.

Three taps, then a pause.

Three more taps. Another pause.

I opened my eyes and stared at the ceiling, trying to identify the sound. It was not the radiator or the pipes. It was too rhythmic for that. Too deliberate.

Three taps. Pause. Three taps.

It was coming from the cupboard.

I sat up slowly, and the blanket slipped from my chest. The room was dark apart from the orange glow of the street lamp filtering through the curtains.

I could see the cupboard door.

It was closed. I had closed it earlier.

The tapping stopped.

I waited. I did not move. I hardly breathed.

Then I heard something else.

Breathing.

Not mine. Someone else's.

Damp and strained, like somebody trying to draw air through a wet cloth. It rattled slightly on the inhale, paused, then exhaled slowly.

It came from behind the cupboard door.

I stayed on the sofa. I did not get up. I did not go near it.

Every part of my mind concerned with logic and reason told me to check. Open the door. Investigate. Find out what was making the noise.

But a much older part, the part that did not trouble itself with logic, told me that opening the door would be the worst idea I had ever had.

So I sat in the darkness and listened to something breathing on the other side of the cupboard. I did not move at all.

I did not open it.

That probably sounds daft. I sat on the sofa with the blanket gathered around my knees, the street light turning everything orange and grey, and listened.

The breathing stopped after perhaps two minutes. It might have been three. I did not check my mobile.

After that, the flat stayed quiet for long enough that I began to wonder whether I had imagined it. Perhaps it was the radiator behaving strangely or the building settling.

Old flats made noises. That was normal.

Then the tapping began again.

Three taps. Pause.

Three more.

The same rhythm. The same muffled quality, like knuckles striking wood from the wrong side of a wall.

It came from the cupboard. Not necessarily from behind the small service door itself, only from that direction. I could not tell whether it travelled up through the floor, down from the ceiling or directly through the wall behind the coats.

I remained on the sofa and checked my mobile.

Half past two.

The tapping stopped.

I waited. I counted to sixty in my head, slowly and steadily, the way Graham had taught me when I was young and could not sleep. It had helped sometimes. It gave my mind something to do besides turn in circles.

Nothing happened.

I drew the blanket tighter and kept my eyes fixed on the cupboard door. It remained shut. The handle did not move. No light showed underneath it, although there was no reason for a light to be down there.

Only old service access. That was what Graham had said.

The tapping returned around three o'clock. The same pattern. Three and three and three.

After that, I began keeping track. Not deliberately, at first. I simply could not help glancing at my mobile whenever it began.

03:17. 03:41. 04:06. 04:23.

The intervals were irregular. Sometimes ten minutes. Sometimes thirty. It never continued for long, perhaps a minute or two at most. Then it stopped cleanly.

It did not sound like pipes. Pipes clanged, hissed or rattled when air became trapped or pressure changed. This was too even. Too deliberate.

Someone tapping to attract attention, or testing whether anyone was listening.

That was the part that bothered me.

At about five o'clock, the sky beyond the window began to turn grey. The street lamps went out. I could see the shape of the cupboard door more clearly, including the edge that did not quite sit flush with the frame.

Graham had never fixed that.

He fixed everything else. Loose cupboard hinges. Dripping taps. The unsteady leg of the kitchen chair. But he had left the cupboard door crooked.

The tapping stopped around half past five and did not return.

I sat there until six, then half past. The flat grew lighter. From the fish bar below came the scrape and clatter of someone rolling up the metal shutters.

A car passed outside. Normal morning sounds.

I got up, folded the blanket and placed it on the arm of the sofa. My back hurt. Sleeping on that thing had always left me stiff.

I stood in the middle of the sitting room for a moment, looking at the cupboard.

Just a door. Wood painted white years earlier, chipped along the bottom edge. Its brass handle was tarnished dark in the grooves.

I needed someone who would tell me I was not being ridiculous. Someone who would know whether this was normal building noise or something else. Someone who would not ask too many questions.

I rang Haroon Malik at about eight o'clock. He answered on the third ring.

"Hi."

"It's Elliot. Elliot Mercer, from housing maintenance."

"Right. Morning."

He sounded as if he had just woken up. He probably had. Haroon worked late shifts most weeks.

"I need a favour," I said.

There was a pause.

"What kind?"

"Just need you to look at something. Old building. Strange noises. Thought you'd know better than me."

Another pause. I could hear him breathing while he considered it.

Then he said, "This about the paperwork?"

"Yeah."

That was the truth of it. The previous year, Haroon had faced a site inspection that should have failed because someone else had entered the wrong dates for electrical testing at a Byker council block.

It would have gone on his record and might have cost him his Newcastle City Council contract. I spotted the mistake during a review and corrected it before anyone more senior noticed. I matched the dates to the signatures and refiled the paperwork properly. It took twenty minutes and saved him a great deal of trouble.

"Where?" Haroon asked.

I gave him the Barrasford Street address. He said he would be there by nine.

I ended the call and made tea. I did not need anything else.

The kitchen felt too bright with the morning sun shining through the window over the sink. I kept glancing towards the cupboard while the kettle boiled.

Haroon knocked at 10:09.

I let him in. He wore work boots, dark trousers and a high-visibility jacket with the council logo across the back. His tool bag hung from one shoulder, and a torch was clipped to his belt.

"All right," he said as he stepped inside.

He looked round the sitting room, taking it in.

"What am I looking at?"

"Service door. In the cupboard."

I showed him.

He crouched in front of the little wooden door and shone his torch over it. The padlock was on the floor where Dean had left it the day before.

Haroon picked it up and turned it in his hand.

"Abus," he said. "Decent lock. New."

"A locksmith opened it yesterday."

Haroon looked up at me.

"Why?"

"Estate clearance. It was my uncle's flat. He died last week."

"Right."

He set the padlock down and ran his hand along the edge of the service door, examining the frame and testing the ordinary latch beneath the handle. It was not locked.

"What's the problem?"

"I don't know yet," I said. "I only want to see what's down there. Make sure it isn't something that needs reporting."

That was mostly true.

Haroon did not need to know about the tapping or the breathing. Not yet. He would think I was losing my mind, and I wanted him to remain long enough to inspect the place.

He nodded.

"Fair enough. Probably old utility access. Most buildings like this have it. Usually sealed off or full of rubbish."

He rose and brushed off his hands.

"Want me to check it?"

"Yeah."

I did not mention the sounds until we were both standing there, facing the door. Haroon held his torch. I had Graham's key ring, with the little brass padlock key resting lightly between my fingers.

"I heard something last night," I said.

Haroon looked at me.

"What sort of something?"

"Tapping. Breathing, perhaps. Could've been pipes."

"Could've been," Haroon agreed.

He did not sound convinced, but neither did he sound sceptical. He was simply neutral. Haroon never committed himself before seeing something first-hand.

"Thought you should know," I said.

"Aye."

He switched on the torch and tested its bright white beam.

"Let's have a look, then."

I crouched in front of the small door. The hasp was still attached, its metal loop hanging free without the padlock. I lifted it clear and pressed the ordinary latch beneath the handle.

It released with a soft click.

I pulled the door open.

Cold air rolled out.

It was not exactly a draught. It was simply colder than the flat, and it smelt different. Old rain and hot dust. That particular smell of concrete that has been soaked and dried too many times, like an underground car park or an old storage cellar.

Haroon leant in beside me and directed his torch through the doorway.

Stairs.

Steep concrete stairs descended beyond it. They were narrow, perhaps sixty centimetres wide. Rough poured concrete formed the walls on either side. There was no handrail and no lighting. Only steps disappearing into darkness.

"That shouldn't fit," Haroon said quietly.

He was right.

The flat was on the first floor above Pritchard's Fish Bar. There was no room for a stairwell like that unless it passed straight through the shop below, and I had been in there plenty of times while growing up.

There were no stairs. Only the counter, the freezers and the back room with its preparation tables.

"Could go beneath the street," Haroon said.

He did not sound certain.

I said nothing. I was staring down the steps, trying to judge how far they descended. The torch reached perhaps three metres before it showed only more concrete.

The air rising from below seemed wrong now. Still damp and dusty, but colder. Sharper.

Haroon went through the doorway first, ducking beneath the low frame.

I followed.

The stairs were steep enough that I had to brace one hand against the wall. The concrete felt rough and gritty beneath my palm. Haroon kept the torch pointed down, moving the beam from side to side as we descended.

Halfway to the first bend, the air changed. It became colder. I felt it first on my face and then on my hands. It was the sort of cold that gathers in a room without ventilation or heating.

Dead air.

Haroon stopped.

"You see that?"

He directed the torch at the wall on our right. A stripe ran horizontally along the concrete at about chest height.

Bright yellow electrical tape.

I knew that tape. It was the sort sold in different colours for marking wires or zones. Graham kept a yellow roll in the kitchen drawer. He used it to mark things: the underside of the sink where the stopcock was, the consumer unit in the hall and the edge of the stepladder where its hinge could pinch your fingers.

Things you were not meant to touch. Boundaries you were not meant to cross.

"That mean something?" Haroon asked.

I stared at the yellow stripe. It continued along the wall as far as the torch beam reached, perfectly level.

"Yeah," I said. "It means don't go past it."

The stairs continued for far longer than they should have. I counted thirty-nine steps before we reached the bottom, an impossible depth for a first-floor flat.

Haroon said nothing about it. He kept the torch aimed down and one hand braced against the wall.

When the steps finally ended, a corridor opened in front of us.

I stopped on the last one and looked at the floor.

It was no longer concrete. The paving resembled period platform tiles from Newcastle Central Station: old cream and brown squares with bevelled edges, modelled on the kind laid decades ago and never entirely replaced. The grout was dark and uneven. Cracks ran across several tiles, but they felt solid when I stepped onto them.

Haroon swept the torch from left to right.

The corridor extended about six metres before curving out of sight. Its walls were painted institutional green on the lower half and cream above, with a wooden rail dividing the colours. Near the ceiling, the paint peeled away in long strips.

I took another three steps and the floor changed.

It simply changed.

The platform tiles ended at a perfectly straight line and became cracked linoleum. It had a pattern presumably intended to resemble marble, though it merely looked grey and miserable. Council offices had used that sort of flooring in the 1980s, before carpet tiles became standard. I recognised it from old photographs in the housing maintenance archives.

"That's strange," Haroon said behind me.

"Yeah."

The lighting was worse.

Over the platform tiles, a fluorescent tube was fixed to the ceiling with metal brackets. It flickered in the slow, irregular way that meant its ballast was failing. The light was a cold blue-white that washed the colour out of everything.

But three metres farther on, where the linoleum began, the light changed completely.

A gas lamp was fixed to the wall. A proper old lamp, with a glass shade and brass fittings. The flame inside remained steady and yellow, casting a warm glow that did not reach far.

I could smell it faintly. Not quite coal gas, but something close. Something that should not have been burning any longer.

Beyond that, farther along where the corridor curved, I could see another source of light. This one was harsh and white, accompanied by a faint buzzing noise that reached us from where it hung.

When Haroon aimed his torch towards it, I saw a bare LED bulb screwed into a ceiling fitting, the kind sold in a DIY shop for three pounds.

Three different lights. Three different periods. All in the same corridor beneath Graham's flat.

I did not know what to do with that information.

Haroon stepped up beside me and stopped. He was looking at the same things.

"This doesn't make sense," he said.

"No."

"Gas lamp isn't connected to anything. There's no pipe."

I looked at the wall where the lamp had been mounted. He was right. The brass fixture was screwed directly into the plaster. No supply line entered it. There was no valve, no visible connection at all.

"It's still burning," I said.

"Aye."

We stood there for a while.

The fluorescent tube flickered twice, went dark and came back on. The gas flame never shifted. The LED bulb buzzed.

Haroon took his mobile from his jacket pocket and checked its screen. Blue light shone up into his face. He frowned, turned the mobile sideways and lowered it.

"No signal," he said.

I blinked.

"What?"

"No bars. Nothing."

He showed me. The signal indicator was empty. No network name, only a small cross where the bars ought to have been.

That did not make sense. We were directly beneath the flat, perhaps twenty metres down at most and probably less. The Wi-Fi in Graham's sitting room had worked perfectly. My mobile had shown four bars there the previous night.

"Check yours," Haroon said.

I took mine out.

The same. No signal, no data and no Wi-Fi networks appearing in the settings. Only a blank list.

"We're not that deep," I said.

Haroon put his mobile away without answering.

I did the same and looked down the corridor again. The fluorescent tube flickered. The gas flame remained steady. The LED bulb buzzed.

I began walking.

I did not really decide to. I simply did it.

Haroon followed without a word. His boots sounded loud on the linoleum after the softer noise they had made on the platform tiles.

The corridor curved gently to the right. As we moved, I watched the walls, the ceiling and the floor, searching for anything that made sense.

Doors stood at uneven intervals along the left side. Plain wooden doors, each with a pebbled-glass window at eye level. The sort found in old office buildings. The glass was too dirty to see through.

The air was still cold, but it no longer felt stale. It seemed to move, almost imperceptibly. Not a draught, exactly.

More as if the space were breathing.

That was when I began to feel watched.

Not from ahead.

From behind.

I did not turn round. I kept walking, matching Haroon's pace, but the feeling did not leave. It pressed between my shoulder blades, at the base of my neck.

It was the sensation you got when somebody stood too close behind you on a railway platform and you knew they were staring even though you could not see them.

The corridor behind us felt occupied.

I thought about turning back. Going up the stairs. Closing the little wooden door. Putting the padlock on again. Leaving the place alone, as Graham had told me to.

The instant I formed the thought, something shifted.

Not a sound. Not movement. Only a change in pressure or temperature, something for which I had no proper word.

It felt as if the corridor had noticed that I was thinking of leaving.

As if it wanted me to try.

The sensation became worse, pressing harder, until I stopped thinking about turning round at all.

Haroon stopped walking. I nearly collided with him.

"There," he said, pointing his torch at the left wall.

One of the doors stood slightly open, perhaps fifteen centimetres. It was enough to reveal darkness inside and a narrow strip of what seemed to be a different floor.

Haroon moved closer and pushed the door open with his boot.

It swung inwards without a sound.

The room was small, perhaps three metres by three and a half. A table stood in the centre with four plastic chairs tucked beneath it, the sort with tubular metal legs and curved seats.

A white plastic kettle sat on the table, a basic model. Its flex was plugged into an extension lead that disappeared into the wall. Beside it stood three mugs, a jar of instant coffee and a stack of paper napkins.

A corkboard hung on the far wall with papers pinned to it. I entered the room and looked more closely. Most of the sheets were blank except for one.

A calendar. The printed sort, with one month on each page.

October 1991.

Beneath it was a plate holding a sandwich. White bread, butter, corned beef and pickle. Cut diagonally.

The bread had not begun to curl at the edges. The filling looked fresh.

"Hello?" I said.

The word escaped before I thought about it.

My voice sounded wrong at once. Flat and small, as if the room swallowed it before it could travel.

Haroon turned sharply and seized my arm.

"Don't."

I closed my mouth.

"Don't make noise," he said.

His voice was low, quieter than mine had been.

"Not here."

"Why?"

He did not answer.

He released my arm and aimed the torch at the floor beside the table.

There were prints in the dust.

Small, bare footprints. The toes were distinct, the arches narrow and the heels rounded. A child's feet, perhaps, or those of someone very small.

They crossed the floor from the doorway to the table, then returned towards the door. They were recent enough that the edges had not softened.

We had been the first people to open that door.

I looked at Haroon. He stared at the prints with his mouth drawn into a narrow line.

"We're leaving," I said.

I turned towards the door and walked back into the corridor. Haroon followed, pulling the break-room door shut behind us. It clicked softly.

I turned left, back the way we had come.

Back towards the stairs, the little wooden service door and the flat above, with its sofa and kettle and ordinary sounds from the street.

I took four steps before I saw the wall.

The corridor no longer curved back the way it had before.

It simply ended.

A rough stone wall, dark grey and uneven, blocked the passage. A metal plate had been bolted into the rock. Its bolts were thick and rusty, the kind used for industrial fittings.

The stairs were gone.

I stood there and stared.

Haroon came alongside me and raised the torch, illuminating the entire obstruction.

"That wasn't there," I said.

Haroon did not answer.

The plate was solid. There were no gaps and no seams, only metal, stone and bolts that looked as though they had been there for fifty years.

I turned and looked back along the corridor, past the break-room door, towards the curve, the buzzing LED bulb and whatever waited farther on.

The only way out was forward now.

That was it.

I turned back towards Haroon.

Haroon still had the torch aimed at the metal plate where the stairs had been. The bolts looked old, properly old. They bore the sort of rust that took decades to form.

"We're going forwards," I said.

Haroon did not argue. He lowered the torch and turned round, and we walked deeper into the corridor, past the break room with the fresh corned-beef-and-pickle sandwich and the barefoot prints in the dust.

I did not look through that doorway again. Haroon stayed ahead of me with the torch, and I kept my hand near the wall without touching it. The paint looked as though it might flake away if I brushed against it. The doors began about three metres beyond the break room. The first on the left had STORAGE stencilled across its pebbled glass in black block capitals.

It was the sort of stencil you might see in any council building from the 1970s. Plain and functional. The door was closed. I did not try the handle.

The next one said BIOLOGY. That bothered me. Not merely because it was strange, though it was, but because the stencil looked newer. The letters had sharper edges and were in a different typeface. The door stood directly beside STORAGE, as though someone had put it there without considering whether the two belonged together.

Haroon slowed as we passed it. His torch beam struck the glass, and I saw shapes inside. Tall shapes. Shelving, probably.

He did not stop. The third door said WAITING ROOM in the same old stencil as STORAGE, but its glass was cleaner. I could almost see through it.

Almost. Just enough to make out the shape of a chair and perhaps a table. The corridor could not decide what it was. That was what got to me. It felt like walking through a building that kept changing its mind about its own history.

Then I saw the next door, and my stomach dropped.

NEWCASTLE CITY COUNCIL.

The words had been stencilled in the same typeface we used at the housing maintenance office. The same spacing. The same slightly crooked alignment caused by the stencil never sitting flat when you taped it to the glass.

I stopped. Haroon turned round.

"What?"

"That's my work," I said, pointing at the door. "That's the same stencil we use."

He aimed the torch at it.

The letters looked exactly right. They were precisely as they should have appeared on any Newcastle City Council office door. That somehow made it worse. Had the name been misspelt or the typeface wrong, it would only have been another strange thing down there.

But it was correct. Familiar. That was what made me feel trapped. Not the metal plate behind us, nor the corridor that could not exist.

This. Something I recognised in a place that should not have been there.

Haroon stepped up to the door and tried the handle. It turned.

He pushed it open, and the smell reached me first. Warm electronics. That particular plasticky heat given off by computers left running for too long. Beneath it lay the faint scorched smell of an overworked printer.

The office was long, perhaps twelve metres. Two rows of fluorescent lights ran along the ceiling. Every tube was lit.

Desks stood in three lines, with swivel chairs either tucked beneath them or pushed back slightly. There were twelve computers, all of them running.

Every monitor displayed the same thing: a blank document, a white screen and a cursor blinking in the top left-hand corner. Haroon went in first. I followed.

The chairs were warm. I knew because I touched one without thinking. My hand merely brushed the backrest as I passed, but the fabric held body heat, as though somebody had been sitting there thirty seconds earlier and had just stood up.

The office was empty. There was not a soul in sight.

The printer stood on a table near the back wall. It was an old Brother laser printer, the sort the council had stopped using years ago because the toner cost more than replacing the machine. It was running, producing one sheet every three seconds in a steady mechanical rhythm.

I walked over and lifted the stack from the output tray. Every page was completely black. No text or images, just toner covering each sheet from edge to edge, as though the printer were trying to drown the paper. The stack was warm and freshly printed. I counted twelve sheets while the machine continued churning out more.

"We need to leave," Haroon said.

His voice was tight.

"Aye."

"Take something useful."

I looked around. Useful? What in that room could possibly be useful? Computers displaying nothing, chairs that still held somebody's warmth, a printer suffering some endless mechanical breakdown.

Then I saw the fire extinguisher. It was mounted beside the door, a standard red canister with a black hose and trigger, the sort found in every council building.

An inspection tag hung from it, dated 14 March 2026. Less than three months before we entered the flat to clear it that June.

I lifted the extinguisher from its bracket. It was heavy and full, and the pressure gauge stood in the green. It was the only object in the room that felt as though it belonged to normal reality. The only thing I understood.

Haroon was already by the door. I followed him out, and he pulled it shut behind us.

The corridor continued. We walked on.

I carried the extinguisher in both hands because it was awkward and I had nowhere else to put it. Haroon stayed ahead with the torch.

Then I felt it: a low vibration in the floor. Deep and rhythmic. The sort of vibration that travels through your chest when you stand on a platform and a train is approaching through a tunnel.

I stopped. Haroon stopped as well. We stood waiting for the train to arrive.

It did not.

The vibration continued, steady and constant, but nothing came. There was no sound of wheels on rails, no change in air pressure and no approaching light. Only the sensation of something enormous and fast bearing down on us from a direction I could not identify.

Then it stopped.

Haroon looked at me. I looked back at him.

"Keep moving," he said.

So we did.

The corridor began to twist. There were no sharp corners, only gradual curves that prevented me from seeing more than six metres ahead or behind. Doors continued to appear, but I stopped reading their labels because the words no longer mattered.

The corridor was making things up now.

We curved right, then left, then right again. Direction ceased to mean anything. I tried to keep track in my head, counting the turns and estimating the distances, but it did not work. The bends were too gentle, and the spaces between them felt inconsistent.

Twenty steps between one turn and the next. Then forty. Then fifteen. By the fourth or fifth bend, I had lost count.

Then I saw the gas lamp.

It was the same one we had passed before. A brass fitting with a glass shade, its yellow flame giving off that faint smell of coal gas despite there being no pipe to feed it.

We had returned to the same place.

Haroon stopped and aimed the torch at the lamp. We had not turned round. I knew that. We had gone forwards the entire time. Yet there it was: the same lamp, the same stretch of corridor with the linoleum floor and the cream and green walls.

Then I noticed the tag. It was fastened to the lamp bracket with a twist of wire.

A small rectangular paper label, white with a red border. I stepped closer. It was a Network Rail equipment label.

I recognised the format at once because Graham sometimes used to bring them home stuck to tools or pieces of equipment he had signed out and forgotten to return. A staff number was printed in the top right-hand corner, with an inspection date below and a space for warning notes at the bottom.

The label bore Graham's staff number. I knew it by heart: 58214. He had kept the same number throughout his career at Newcastle Central Station.

The inspection date was 19 January 2025. In the warning section, Graham had written two lines in tight block capitals with a blue ballpoint pen.

YELLOW STRIPE MATTERS.

PLATFORM NUMBERS MATTER MORE THAN DOORS.

I stood staring at the tag while Haroon directed the torch over my shoulder.

"That mean something to you?" he asked.

"It's my uncle's. He wrote this."

The gas flame flickered. The corridor behind us remained silent.

Graham had been down there. He had marked that lamp and left a warning. Now we were following his route with no way back.

That was when I stopped trying doors. Haroon stood with his torch trained on the gas lamp and Graham's label hanging from its bracket, while I looked at the corridor stretching away on both sides.

The same walls. The same floor. The same gradual curve.

I thought of Graham travelling the same route to Newcastle Central Station every day for more than thirty years. Coming home at the same time. Locking the dark red front door. Checking the service-door padlock before bed. Putting yellow tape on everything that mattered.

It had not been superstition. They were instructions.

I looked down.

A stripe of yellow electrical tape ran along the wall at shin height, about fifteen centimetres above the floor, perfectly level. I had seen it when we came down the stairs, but I had not followed it. I had been too busy looking at the doors.

"We're following the stripe," I said.

Haroon lowered the torch towards the tape.

"That's it?"

"That's it."

I started walking, keeping the yellow line in view. Haroon followed without arguing. The extinguisher weighed heavily in both hands and my shoulders had begun to ache, but I was not putting it down.

The corridor curved right and then straightened. Doors continued to appear, but I ignored the labels and watched the stripe.

After about twelve metres, the stripe dropped lower. It did not slope down gradually. It shifted by another eight centimetres at a clean angle, as though Graham had measured the change deliberately.

I kept walking.

The walls changed from painted plaster to plain grey concrete, rough and cold when my knuckles brushed it. The yellow stripe continued, bright against the grey. The echoes of Haroon's boots grew sharper, with less softness to absorb them.

I glanced back. He had the torch pointed down, following the tape with its beam.

Three metres farther on, I saw the first marker. It was bolted to the wall about thirty centimetres above the floor, partly concealed behind a vertical pipe running from floor to ceiling.

It was a small white enamel rectangle bearing a single black number.

One.

I stopped. Haroon nearly walked into my back.

"What?"

I pointed. He crouched and angled the torch towards it. The enamel was chipped around the edges, but the number remained clean and sharp. It was modelled on the old platform markers at Newcastle Central Station, the sort used to indicate where carriages should stop.

"Platform marker," Haroon said.

"Aye."

I continued. The stripe led forwards, and I counted my steps without intending to.

Twenty-three steps later, there was another pipe and another sign behind it.

Two.

Haroon said nothing, but I could hear his breathing growing heavier.

Thirty steps farther on, we found number three. The corridor no longer curved. It ran straight, its concrete walls narrowing slightly. The ceiling dropped by about fifteen centimetres, forcing Haroon to duck beneath a low beam.

The fluorescent lights had gone. Bare bulbs hung at wide intervals, some of them flickering.

Four.

Five.

I realised I was following Graham's route. Not the one he had taken to work, but the one he had used down there.

However many times he had passed through the service door, he had followed that yellow stripe and counted those numbers. He had known precisely where he was going. Everything he had done upstairs made sense now.

The yellow tape on the fuse box. Dinner at the same time each evening. Checking the padlock before bed. He had not merely been rigid.

He had been practising.

Number six appeared behind a bundle of cables. The enamel was so old that the white had yellowed.

"How far?" Haroon asked behind me.

"I don't know."

Twenty steps later, we found number seven. Beyond that, the corridor narrowed further before marker eight appeared beside a rusted junction box. Marker nine stood behind a thick iron conduit where the passage opened out.

It did not lead into another corridor.

It opened into a room shaped wrongly: long and narrow, with a high ceiling that vanished into shadow above the weak light from the bulbs. At the far end stood a massive black buffer stop, the sort installed at terminal platforms to prevent trains rolling beyond the end of the track. Its rusted frame and thick springs were bolted into the floor.

Beyond it was nothing. Only a drop into darkness where the track should have been.

The floor was laid with the same period tiles we had seen at the top of the stairs, modelled on those at Newcastle Central Station: cream and brown, with bevelled edges and dark grout.

A wooden bench stood against the left-hand wall, about three metres from the buffer stop. Graham's satchel rested on it.

Old brown leather. Worn strap. Brass buckle.

I had seen it every day while I lived with him. He had carried it to work, brought it home and set it beside the front door. I had always assumed it held nothing more than his lunch and his flask.

I walked over. Haroon stayed near the entrance, holding the torch.

The satchel was not dusty. It looked as though someone had placed it there five minutes earlier. I set the extinguisher on the bench and opened the buckle. The leather was stiff, but it yielded.

There was a notebook inside. Spiral-bound and A5, the sort sold at any corner shop. Its cover was blank.

I took it out and opened it.

There were sketches. Corridor plans drawn with a ruler in blue ink. Labels in Graham's handwriting.

STORAGE - EMPTY.

BIOLOGY - DON'T OPEN.

COUNCIL OFFICE - SAFE IF QUICK.

Numbers marked distances. Notes explained the stripe.

FOLLOWS ORIGINAL MAIN-LINE ROUTE. STAYS LEVEL EXCEPT FOR DROP AT JUNCTION.

I turned the pages. There were perhaps thirty or forty sheets of maps, showing different routes and different markers. Warnings filled some of the margins.

BREATHING STARTS NEAR BREAK ROOM AFTER MIDNIGHT.

FOOTPRINTS RESET WHEN DOOR CLOSES.

DON'T ANSWER IF IT SPEAKS.

On the last page was a sketch of the room with all nine platform markers shown on the approach. Graham had drawn the buffer stop and the bench. A circle marked the place where I stood, with an arrow pointing towards it and two words beside the arrow.

RETURN TOKEN.

I searched the satchel again. Something heavy moved at the bottom.

I reached in and took out a thick brass token about the size of a ten-pence piece. One face bore the castle emblem of Newcastle and the words NEWCASTLE CORPORATION TRANSPORT. The other carried a single stamped word.

RETURN.

The token had been taped inside a plastic sleeve of the kind once used for bus passes. On the sleeve, Graham had written in blue ink:

ONE USE. CORRECT GATE ONLY. DON'T LOSE IT.

My hands began to shake.

"Elliot," Haroon said quietly.

I turned.

He had aimed the torch beyond the buffer stop, towards the drop at the far end of the room.

Something stood there.

It was not on the edge. It was down in the drop, as though a floor continued through the darkness where the light could not reach. A small figure. The height of a child. Barefoot.

It was not moving. It merely stood in the blackness, facing us.

The silence came first, the sort that made my ears ring.

Then I heard footsteps.

Slow. Deliberate. Bare feet on tile.

The figure began walking towards us. It did not climb out of the drop. It walked on the level, as though there were an invisible platform beneath it.

As it approached, it became taller. It did not grow. It unfolded.

Its proportions shifted smoothly. Its shoulders widened, its legs lengthened and its head rose until it was the height of an adult.

My height.

Haroon swept the torch across it, and the beam caught it fully for half a second.

It looked like me. The same build, the same jacket, the same habit of resting my weight on my left foot.

Then it smiled, and its face was wrong. The mouth stretched too far, extending beyond the point where a mouth should end.

I grabbed the satchel. Haroon was already moving, backing towards the entrance.

I snatched the extinguisher from the bench and ran.

Footsteps followed us, faster now, matching my stride exactly.

Haroon shouted something I did not catch. Beyond the entrance, the corridor divided into three passages. He took the right-hand one without slowing, and I followed.

The yellow stripe was gone. We had left the route.

The passage narrowed until Haroon had to turn sideways to squeeze through with the torch. I scraped my shoulder against the concrete, and the extinguisher clanged against the wall.

Behind us, the footsteps continued, still matching mine.

The passage opened into a small concrete room, perhaps two and a half metres square, with a bare bulb overhead. In the centre stood an old-fashioned turnstile, waist-high, with three metal arms. It was the kind used on the railway decades ago and was painted the dark red of the British Rail era.

A metal sign bolted to the wall above it read RETURN.

I pushed Haroon towards it. He seized one of the arms and shoved. It did not move.

"Token," he said.

I fumbled open the satchel, pulled out the plastic sleeve and tore away the tape. The brass token felt warm in my palm.

Behind us, in the narrow passage, something was breathing. The sound was damp and strained.

I forced the token into the turnstile's slot. It dropped with a heavy clunk that echoed wrongly, as though it had fallen much farther than the mechanism allowed.

Nothing happened.

Haroon pushed again. The turnstile remained locked.

The breathing came closer.

Then there was a click deep within the mechanism, the sound of something old waking up.

The turnstile arms shifted. Haroon shoved through as the metal bars began to rotate smoothly. He stepped beyond them and stopped.

"There's a door," he said.

I could not see past him. I pushed against the turnstile. The arms rotated, and I ducked through.

On the far side stood a plain wooden door, painted cream and fitted with a brass handle. It had not been there a second earlier.

Haroon grabbed the handle and pulled. The door opened on bright light and warmth.

I smelt dust and old coats.

Haroon stepped through and vanished.

I turned to follow, and something closed around my ankle.

It was cold and hard, with the bruising pressure of fingers made from stone.

I looked down. A pale, unnaturally long hand gripped my ankle from beneath the turnstile.

There was no arm attached to it. Only the hand.

I kicked. It held on. I kicked again, harder, and the extinguisher slipped from my grasp and struck the floor.

The hand tightened. Something shifted in my ankle, the pressure building towards a break.

I gripped the turnstile arm with both hands and dragged myself forwards. The hand hauled me back. I planted my free foot against the turnstile's base and shoved.

The fingers released me.

I fell through the doorway and landed on carpet. It was warm, soft and familiar.

Behind me, the door slammed.

I was lying on the floor of Graham's hall. The cupboard door stood open in front of me. Inside, the small wooden service door was shut. The Abus padlock was back on the hasp, closed and warm when I reached out and brushed it.

I stood. My ankle throbbed, but it took my weight. The satchel was still over my shoulder.

Haroon was not there.

I took out my mobile. The signal had returned. Four bars.

I rang him. The call went straight to voicemail.

I rang again. Voicemail.

I tried another sixteen times over the next two days. Every call went straight to voicemail. On the third day, I rang the council depot and asked for Haroon Malik.

The woman who answered told me he had resigned the week before our expedition. No notice. According to their records, he had simply stopped turning up.

I checked the satchel that night. Graham's notebook was still inside. The plastic sleeve was empty.

The token had gone.

Over the next two weeks, I cleared what I could from the flat above Pritchard's Fish Bar. I did not touch the bedroom and did not reopen the service door. The usual smell of vinegar, frying fat and damp newspaper continued to rise through the floorboards as if nothing had happened below them.

I moved my essentials back to my studio flat in Heaton and abandoned the rest.

I put Graham's flat on the market on 9 November 2026. The sale completed on 22 January 2027. Once the keys changed hands, I never went back.

I kept the satchel. It was the only thing I trusted as proof.

Haroon never rang. He never came home. Newcastle City Council still had his departure recorded as a voluntary resignation. I asked around once, but nobody knew anything.

I live in Jesmond now, in a third-floor new-build flat made of concrete and plasterboard. There are no old doors and no service access. I checked before I signed the tenancy.

But sometimes, late at night, when the street has gone quiet, I hear it.

Three taps.

A pause.

Three taps.

Muffled, as though they are coming from inside the walls.

I do not go looking.
