The Cistern on Church Street

The satnav kept losing signal somewhere beyond Guisborough, which felt about right for the way the whole week had gone. I had my mobile wedged into the air-vent mount with five per cent battery left and no charging lead because I'd left mine plugged into the wall at the flat. The flat I probably wouldn't have by the end of the month if this house-sitting job fell through. Five nights beginning 14 November, 400 pounds in cash on the final morning.

That was the deal, and it was the only thing keeping my motor insurance from lapsing and my landlord from starting possession proceedings. I had about 29 pounds in my account, enough petrol to reach Whitby but not enough for much else. The distribution centre had cut my shifts three weeks earlier, just like that. No warning, only a text saying they were adjusting the rota, and I'd gone from four shifts a week to one, occasionally two if someone rang in sick.

I picked up a weekend at another depot unloading furniture, but that dried up quickly. Then my flatmate decided to move in with his girlfriend and disappeared halfway through October, leaving me with his share of the November rent as well as mine. I tried every gig app I could find. Deliveroo had put me on a waiting list for new riders in my area.

Private-hire work required licensing and vehicle checks I couldn't afford. Airtasker got me one removal job for 16 pounds, and the bloke didn't even tip. That was it. So when I saw the house-sitting post in a local Facebook group I'd joined while considering restoring and reselling charity-shop and house-clearance furniture, I replied within five minutes.

The advert was bare.

"Responsible sitter needed for small historic property in Whitby. Five nights beginning 14 November. 400 pounds. Must follow house rules.

Contact Margaret Wycliffe."

I sent her my number. She rang twenty minutes later and asked whether I could start that evening. She didn't ask for references.

She didn't even ask for my surname. She only confirmed that I had transport and could arrive before 18:00. I said yes before she'd finished speaking. I probably should have asked more questions.

That was me, though. Desperate, and never very good at spotting red flags until I was already standing among them.

The journey took longer than it should have. The sun was sinking by the time I reached Whitby, throwing a dull orange haze between the buildings. I didn't know the town particularly well. I'd visited once on a North Yorkshire school trip in Year 9. We'd seen Whitby Abbey and been marched around a museum while a teacher tried to make us take notes.

It looked different now. Older, somehow. Or perhaps I was simply exhausted. Church Street was narrow and cobbled, close to the old harbour and the historic East Cliff quarter but just far enough from the busiest stretch to feel quiet.

The satnav abandoned me at the corner, and I spotted the house halfway along the street. It was small, built of whitewashed stone, with a slate roof and black wrought-iron grilles over the front windows. A wooden gate blocked the entrance passage, fitted with a heavy latch and decorative iron curls along the top.

Margaret Wycliffe was already there, standing beside a silver Skoda Fabia with its engine running. She looked exactly as she'd sounded on the phone: somewhere in her sixties, with short silver-blonde hair, smart black trousers and a cardigan despite the cold, damp November air. It was about 9 degrees Celsius.

She checked her watch as I pulled up.

"Callum Price?"

"Yeah."

I got out and locked my car. My trainers were scuffed to hell, and my hoodie had a stain on one sleeve that I'd stopped trying to remove. I assumed she noticed.

"Good. Let's get you oriented quickly."

She didn't smile. She turned and unlocked the gate with a key from a ring clipped to her handbag.

"I have an appointment at 19:00, so we'll need to move."

I followed her through the entrance passage into a small courtyard paved with weathered sandstone flags. There were a couple of potted plants that looked artificial but probably weren't, and an iron bench with rust creeping up its legs. The house wrapped around the courtyard in an L-shape, all white stone and dark timber. The front door was painted deep green and fitted with an old brass knocker shaped vaguely like a lion.

Margaret moved quickly. She unlocked the door, stepped inside and began speaking before I'd crossed the threshold.

"The alarm code is 4826. You'll need to enter it within thirty seconds of opening any exterior door. Don't forget, or the monitoring company rings, and they're difficult."

She entered the numbers into a beige keypad just inside the hall. It beeped twice and a small green light appeared.

"The Wi-Fi password is on the counter. Kitchen through there, bathroom off the hall, bedroom upstairs. The linen is clean."

I nodded, trying to keep up. The inside of the house was dim and smelt faintly of lemon polish and something else I couldn't identify. Old timber, perhaps.

The walls were white plaster, the floors uneven sandstone and dark boards, and every piece of furniture looked expensive in that understated way where nothing matched but everything belonged together. A glazed earthenware bowl stood on a side table. A woven rug looked handmade. The books on the shelves appeared old but carefully kept.

The place felt staged. That was the word that came to me. As if someone had arranged it to suggest a life without allowing any actual mess.

Margaret showed me through the tiny kitchen and pointed out the courtyard door. It opened onto the same courtyard I'd entered from, but from the opposite side. Then she stopped at the foot of a narrow staircase and pointed to a door I had almost missed.

It was low, about 1.5 metres high, painted the same white as the wall and set awkwardly into the space beneath the stairs. Its brass knob was much higher than it ought to have been, as though whoever had installed it had never measured where a hand would naturally reach.

"This door stays closed," she said.

I looked at it.

"All right."

"I mean it."

Her voice sharpened.

"It leads down to an old cistern. The house was built in the eighteenth century, and the cistern was used to store water. It isn't safe. The steps are rotten and the chamber is flooded."

"Understood. I won't open it."

She didn't move. She looked at the door, then back at me.

"You may hear water moving below, especially at night. Harbour groundwater, tidal seepage, old foundations. Don't let it concern you, and don't open the door to investigate."

That bothered me slightly. It was the way she said it, flat and firm, as if she expected me to be tempted. I had no intention of opening some strange cellar door. I didn't even like cellars.

"Fine," I said. "No problem."

She studied me for another second, then reached into the canvas tote she was carrying and took out a folded Co-op paper bag. She passed it to me. I opened the top enough to see what was inside.

Oyster shells. An entire bag of them, cleaned but unmistakable.

"If you become anxious," she said, "scatter some of these across the thresholds. The front door, the courtyard doors, the foot of the stairs. It's an old seafarers' ward. Some people find it calming."

I stared into the bag.

"For luck?"

"Something like that."

I didn't know what to say. It sounded like the sort of superstition somebody's grandmother might insist upon, but Margaret spoke so matter-of-factly that I merely nodded and folded the bag shut. It wasn't worth arguing about. If she wanted me to scatter shells, I'd scatter shells.

Four hundred pounds was four hundred pounds.

"All right," I said.

She led me back to the front door and handed me a single key on a plain metal ring.

"Lock everything at night. Don't let anyone in. If there's an emergency, my number is beside the Wi-Fi password on the kitchen counter."

"Got it."

She stepped into the courtyard, and I followed her to the outer gate. She locked it behind herself with a quick, practised movement, tested the latch twice, then got into the Skoda without saying goodbye.

I watched her drive away. Church Street became quiet again. There was nobody else about. Just me, the house and a bag of oyster shells I had no idea what to do with.

I went back inside, locked the front door and entered the alarm code. The beep sounded too loud in the empty hall.

The house was silent. Not peaceful, exactly. Quiet in a way that made me notice small things: the hum of the fridge in the kitchen, the faint complaint of the floorboards when I shifted my weight, the way light through the wrought-iron window grilles cast shadows that didn't quite line up with the furniture.

I dropped my rucksack on the sofa and looked around.

Five nights. That was all I had to manage.

Keep the place standing, don't open the odd little door, and perhaps scatter a few shells if I felt like it. Easy money. I kept telling myself that.

At about half past eleven, I was on the sofa scrolling through my mobile with the brightness turned down to save the battery when the courtyard light clicked on.

I hadn't touched the switch. I wasn't even near it. The switch was in the kitchen, an old-fashioned toggle beside the door frame. I'd noticed it when Margaret showed me round, but I hadn't used it. There had been enough light from the street to make out the fountain and the potted plants without it.

Now the entire courtyard was illuminated by a harsh white fixture above the kitchen door. Margaret hadn't mentioned a security light, but that had to be what it was.

I sat up and put my phone on the sofa cushion.

Probably a fox or a stray cat. Whitby had to have plenty of both, especially around the harbour. It made sense.

I remained on the sofa for perhaps thirty seconds, telling myself it was nothing. Then I got up and went into the kitchen, because I've never been good at leaving things alone.

The window above the sink looked directly into the courtyard. I stood with my hands on the counter and leaned forwards to see past the frame.

That was when I noticed the figure beside the fountain.

Their head was bowed. Long hair hung forwards, hiding the face. Their shoulders were hunched and their dark clothes were soaked. Water dripped from them onto the sandstone flags.

They simply stood there. They didn't move or look around. It appeared as though they'd climbed out of the fountain itself, which was impossible. The basin was barely sixty centimetres across and held only a few centimetres of water.

My stomach dropped and tightened at the same time. For several seconds I did nothing but watch.

The figure remained perfectly still. Water gathered around their feet. Their shoulders rose and fell slightly, as though they were breathing hard or trying to recover their breath.

All right. Someone was in the courtyard. Someone who shouldn't have been there. Either they were trying to frighten me or they genuinely hadn't realised it was private property.

I decided the sensible thing was to scare them off. I struck the window three times with the flat of my hand, hard enough to rattle the glass in its frame.

"Hey!"

The figure didn't react. They didn't flinch, raise their head or move at all.

I hit the glass again, harder. Nothing.

That was when it began to feel wrong.

I stepped away from the window and approached the kitchen door, the one Margaret had shown me earlier. A chain was fixed near the top of the frame, like the cheap sort fitted to rented flats. I checked that it was engaged before unlocking the deadbolt and opening the door by about ten centimetres.

Cold air struck my face. It smelt of wet stone and something else.

Salt, perhaps. Seawater.

"Hey!" I called again, louder. "This is private property. You need to leave."

The figure kept their head lowered, hair hanging across the face.

But their mouth moved.

I couldn't hear what they were saying. It looked like whispering or counting. Their lips repeated the same rhythm over and over.

"I'm calling the police," I said.

I tried to make my voice sound firm and confident, the sort of voice that convinced people you meant what you said and weren't just some broke bloke desperate enough to accept a dodgy house-sitting job from a stranger.

The courtyard light snapped off.

There was no flicker or warning. The whole space vanished into darkness. I froze with one hand on the door.

Then the light came on again.

The courtyard was empty.

I opened the door slightly farther, keeping the chain fastened, and leaned out as much as I could. I scanned the entire space. The fountain stood exactly where it had been.

There was no water on the sandstone. No wet footprints. No sign that anyone had stood there at all. The potted plants hadn't shifted. The iron bench looked untouched. Everything was still, silent and completely undisturbed.

I pulled back inside and locked the deadbolt. My hands were trembling, though only enough to make me miss the lock on my first attempt.

I went through the ground floor and switched on every light I could find: the hall light, the lamp beside the sofa, the bathroom ceiling light, the little reading lamp fixed to the wall by the stairs. The house brightened room by room, and each switch made me feel marginally better.

I checked the front door. Still locked. Deadbolt secure. The alarm keypad still showed green.

I checked the courtyard door again. Locked, with the chain in place. Then I returned to the kitchen window for one last look.

The courtyard was empty. The fountain held perhaps three centimetres of water in the bottom basin, exactly as before. No ripples. No movement.

Nothing had been forced. Nothing was missing.

I walked back towards the sitting room, and that was when I noticed the door beneath the stairs.

It was open.

Not wide. Only a narrow crack, perhaps a centimetre. I stopped in the middle of the hall and stared at it.

Margaret had told me to keep it shut. She'd told me it led to a flooded cistern with rotten steps. She'd told me not to open it.

I hadn't opened it. I'd been on the sofa until the courtyard light came on. I hadn't gone near the stairs or touched the door.

I approached and crouched in front of it. The brass knob was too high, almost level with my chest when I stood upright. From where I knelt, I could see a thin strip of darkness between the door and its frame.

Cold air seeped through the gap. I felt it against my face, damp and briny, carrying the same smell I'd noticed at the courtyard door.

Salt, wet stone and something older. Something that tightened my throat.

I reached forwards and pushed the door shut. It moved easily, without resistance, and clicked into place with a soft noise that seemed far too loud in the quiet house.

The cold draught stopped.

I stayed crouched for a few seconds with my hand on the brass knob, waiting to see whether the door would drift open again.

It didn't.

I stood and took out my mobile. I found Margaret's number in my recent calls and wrote a message.

The door under the stairs was open. I've closed it. Just letting you know.

I sent it and returned to the sofa. My phone buzzed perhaps ten seconds later.

Margaret Wycliffe.

Do not open that door under any circumstances. I was very clear about this.

I read it twice. She had replied so quickly that it felt as if she'd been waiting with her phone in her hand, expecting exactly that message.

I typed back.

I didn't open it. It was already open when I noticed it.

The three dots appeared at once. Then came her reply.

It must remain closed at all times. If it opens again, close it and do not look inside. Do you understand?

I sat staring at the screen. Yes, I understood. I simply had no idea what the hell I'd agreed to.

I tried to sleep on the sofa with my mobile in my hand. I left the screen unlocked because I didn't want to waste time entering a passcode if something happened. The battery had fallen to thirteen per cent by then.

Every light downstairs remained on, making the room feel flat and exposed. I could see the coffee table, the blank television reflecting the lamp, and the corner of the kitchen doorway. Everything was visible. That was supposed to help.

I closed my eyes sometime after 01:00 and kept reminding myself it was an easy 400 pounds. Stay put. Don't overthink it. Old houses made noises.

Security lights came on by themselves all the time. A fox, a stray cat, dodgy wiring, whatever. The door beneath the stairs probably hadn't caught properly when Margaret last shut it.

I almost believed it.

At around 02:00, dripping woke me.

It wasn't the distant, background sort of drip you could ignore. It sounded much too close, like water falling onto timber beside my head.

I opened my eyes but didn't move. I only listened.

The sound was steady and soft, yet somehow deliberate. It came from less than a metre away.

I turned my head towards the coffee table.

Wet fingerprints marked the wood. They were long and thin, as if someone had dragged themselves up from the floor.

I stared for perhaps five full seconds, trying to make them into something else. A ring left by a glass I'd forgotten. A smudge from when I put down my rucksack. Anything ordinary.

But they were too distinct.

Four fingers and a thumb, elongated, with the grain darkening beneath the water.

Another print appeared while I watched.

It simply formed, a wet outline pressing itself into existence beside the first. Droplets gathered around its edges.

Then another appeared.

They were building a slow trail towards the hall.

I lurched upright and struck the coffee table with my knee, knocking the lamp from the side table. It hit the floor and the bulb burst with a sharp crack. I didn't even look down.

The new prints stopped forming.

They stopped mid-trail, as if whoever made them had paused. The earlier ones remained glossy, catching the ceiling light. They didn't evaporate or fade. They looked almost oily.

I stood breathing too quickly, my phone still clenched in one hand, staring at the trail leading from the coffee table towards the hall, the stairs and the cistern door.

My brain tried to repair the situation. A leak in the ceiling. Condensation dripping from somewhere. Perhaps I was still asleep.

But I wasn't asleep. There was no leak, and the prints had knuckles.

I looked at the Co-op bag on the floor beside the sofa, where I'd left it after Margaret handed it to me.

The oyster shells.

She'd said to scatter them across the thresholds if I became anxious. An old seafarers' ward. Some people found it calming.

I grabbed the bag without thinking and went straight to the kitchen door leading to the courtyard.

My hands were shaking, but I managed to open the bag without spilling its contents. The shells were rough and irregular. They smelt faintly of bleach, with something older beneath it.

I crouched and sprinkled a line across the threshold, close against the foot of the door where it met the floor.

I felt ridiculous. I wasn't superstitious and never had been, but I treated the shells like a practical barrier. Like sealing a draught or putting a towel beneath a leak. Something you did because it was the only thing available to do.

The shells clicked softly as they settled. I used about a third of the bag, making the line solid and leaving no gaps.

Then I stood and waited.

For nearly an hour, nothing happened. I sat at the kitchen table with the bag of shells in my lap and my mobile face-up beside my elbow, watching the courtyard door.

The microwave clock changed to 02:47, then 02:53, then 03:09. The house settled around me with its ordinary creaks and hums. The fridge cycled on and off. Wind rustled faintly outside.

Nothing strange. Nothing wrong.

I nearly persuaded myself it had been plumbing. Old pipes. Water hammer. Tidal seepage beneath the foundations.

The fingerprints were probably condensation after all, and I'd panicked because it was the middle of the night in an unfamiliar house and I was already unsettled by the figure in the courtyard.

That was what I told myself.

Then the shells began to click.

One at a time, like careful footsteps.

I sat upright and stared at the line across the threshold. The shells weren't moving. I could see them clearly beneath the kitchen light, the same rough crescent shapes I'd scattered an hour earlier.

But the sound came from there. Tiny, distinct clicks, each separated from the next by about two seconds.

The door handle turned slightly.

I watched it rotate perhaps fifteen degrees, then stop.

It turned again, more slowly this time.

Testing.

The chain remained fastened near the top of the frame. I could see it from the table, taut and secure. The deadbolt was locked.

Something was trying the door, and whatever it was had no need to hurry.

I should have looked away. I should have gone upstairs, shut myself in the bathroom or moved literally anywhere else. Instead, I remained frozen at the table, watching the handle turn in tiny increments as though someone were working out how it functioned.

Then something pressed against the glass.

The top of the door contained a small pane, perhaps twenty centimetres by thirty, made from old rippled glass that distorted whatever stood beyond it. Even so, I could see the shape.

Rounded. Smooth. Larger than a hand.

It flattened itself against the outer surface of the pane. Beneath it was a single dark mark.

It looked like an eye submerged in water.

It didn't blink. It was simply there, watching.

I snatched up my mobile and opened the keypad. My thumb was shaking so badly that I nearly dropped the phone.

I didn't ring 999. I wanted a record without declaring a full emergency. I wanted somebody to know that something was happening without having to explain the wet fingerprints, the oyster shells and the thing that appeared to have climbed from a courtyard fountain.

I searched for the police non-emergency number and rang 101 before I could reconsider.

The rounded shape remained against the glass. The handle stopped turning.

The shells continued clicking, one by one, soft and patient, while I sat with the phone against my ear and waited for someone to answer.

I was transferred twice before an operator told me that a police constable would attend when one was available, probably within the hour.

I remained at the kitchen table, watching the courtyard door until the shape withdrew from the window and the clicking ceased.

It all stopped at once, at about 03:40.

I didn't move the shells. I left them exactly where they were across the threshold.

PC Daniel Hargreaves arrived at 04:28, which technically wasn't much beyond the estimate but felt considerably longer. I heard a car pull up and saw its lights sweep across the wrought-iron window grilles. There was one quick knock, followed by a man's voice through the door.

"North Yorkshire Police."

I went to the peephole. A uniformed constable stood outside, with a marked police response car idling in the street behind him.

I unlocked the deadbolt and opened the door.

He looked tired. Not the way I felt, jittery and overstimulated from watching wet fingerprints appear on furniture, but ordinarily end-of-shift tired. He was tall and solidly built, with close-cropped hair, and looked to be in his late thirties. A torch hung from his equipment belt, and he already had a notebook in hand.

"You reported a disturbance," he said.

He didn't ask my name. He didn't ask whether I was all right.

"Yes. Someone was in the courtyard at the back."

He nodded once and wrote something down.

"Did you see them leave?"

"No. They just... it stopped."

I couldn't work out how to finish the sentence without sounding deranged.

"They were there, and then they weren't."

PC Hargreaves looked up from his notebook.

"Right. Are you the owner?"

"I'm house-sitting for Margaret Wycliffe."

Something shifted in his face when I said her name. It was barely anything, a brief flicker before his expression returned to neutral.

"Right. All right. Mind if I look round the back?"

I stepped aside to let him enter.

He walked through the house as though he'd been there before. He didn't wait for me to show him the way. He went directly through the kitchen to the courtyard door, then stopped when he saw the oyster shells.

"That's new," he said.

"Old tradition," I replied. "For luck."

He made a noise that might have been a laugh, or merely air passing through his nose. Then he unlocked the deadbolt I'd secured after the shape withdrew and stepped into the courtyard.

I stayed in the doorway and watched him inspect the space with his torch. He checked the fountain first, directing the beam into the basin. He crouched beside it and ran a hand along the rim. Then he examined the potted plants and the bench, walked the perimeter and tested the gate latch twice.

"Nothing here," he called.

"There was."

He came inside and locked the door behind him, which I appreciated even if he appeared to do it automatically.

"Look," he said, "old houses like this settle. Pipes expand and contract. You get leaks and noises. It's normal."

"I saw someone."

"Right."

He wrote something else in his notebook.

"And what were they doing, exactly?"

"Standing beside the fountain, dripping wet."

"Dripping wet," he repeated in a flat voice.

"Yes."

"In November."

I didn't answer.

PC Hargreaves clicked his pen and tucked the notebook into his belt.

"Here's my advice. Don't stare through windows at night. Your eyes play tricks. Shadows, reflections, whatever. Your brain supplies the rest. It happens all the time."

"Sure."

He studied me for a moment, then passed me and entered the hall.

"Did Margaret tell you anything about the house when she hired you?"

"Only the basics. Alarm code. Don't let anyone in."

"Right."

He moved farther into the sitting room, and I realised he was looking at the door beneath the stairs.

"That's the cistern access?"

My stomach dropped slightly.

"Yes."

"Mind if I inspect it? Liability issue. If somebody did get in, they might have gone down there."

"It's locked," I said.

That was a lie, but I said it anyway.

"Right."

He walked towards the stairs. Without thinking, I moved between him and the door.

He stopped and raised an eyebrow.

"Is there a problem?"

"Margaret said not to open it. The steps are rotten, and it's flooded below."

"I'm aware. I'm only conducting a sweep."

"You've already checked the courtyard. Nobody's here."

We stood facing each other for several seconds. He had perhaps fifteen kilos on me, along with the uniform and probably some legal argument about obstructing a constable. But I didn't move.

At last he breathed out through his nose and stepped back.

"Fine. Your decision."

He took out his notebook again and wrote something that seemed to take far longer than it ought to have.

When he finished, his expression had changed. He looked less tired and more irritated.

"People house-sit here fairly regularly, you know. We've never had this many calls from one person in a single night."

I'd made one call, not several. I didn't correct him.

"Margaret has a reputation to protect," he continued. "A property like this has its Grade II listing, the council conservation team and local tourism interests involved. The last thing she needs is somebody causing a scene."

"I'm not causing a scene."

"Good."

He put the notebook away.

"Keep it that way."

He showed himself to the front door. I followed, mainly to ensure he actually left.

He paused on the threshold and glanced back at me.

"Get some sleep. You look like hell."

Then he was gone.

I locked the door and watched through the window grille as he climbed into the response car. He remained there for a minute, writing more notes, before finally driving away.

I stood at the window until the rear lights disappeared.

The sun rose at about 07:00. I'd been awake for something like twenty-eight hours, but I didn't feel capable of sleeping. Partly because of the adrenaline, partly because whenever I closed my eyes I saw wet fingerprints forming on the grain of the coffee table.

I left the shells where they were and went upstairs to shower. The bathroom was small, containing only a toilet and a narrow shower enclosure lined with tiles that had probably been white sixty years ago. The water pressure was decent. I stayed beneath the spray until the hot water ran out, which took perhaps eight minutes.

When I came downstairs, the house looked ordinary. Morning light came through the front windows. There were no wet prints and no cold air leaking from beneath the cistern door. The courtyard was empty, and the fountain looked dry apart from the few centimetres of standing water in the bottom basin.

I considered staying indoors. I could sit on the sofa, watch the house and wait it out.

But I needed food. My mobile had fallen to six per cent, and I didn't have the right charging lead with me. The house had ordinary UK sockets; the problem was entirely mine.

More than that, I needed to leave for a couple of hours before I began questioning what I'd really seen.

I took my wallet and keys and went out at about 09:00.

Whitby in daylight was a different place. Tourists were everywhere. Families pushed buggies along the harbour, and couples stopped for photographs with the Abbey visible above the town. I passed a man in old-fashioned seafaring clothes giving a ghost-walk speech near a street corner, his voice carrying over the traffic as he described quarantined foreign sailors and a wrecked Spanish merchant vessel.

It all felt unreal, as if I'd stepped out of one world and into another.

I found a small Co-op Food shop and bought the basics: bread, peanut butter, two tins of soup, bananas and a box of cereal bars. I picked up a charging lead from a rack near the till.

The total came to just over 21 pounds, leaving me with only a few quid until Margaret paid me. The cashier looked about nineteen, with a blonde ponytail and a name badge that read Lucy.

She smiled as she handed me the receipt.

"Are you visiting?"

"Working."

"Oh, right. Whereabouts?"

"Church Street."

Her smile faltered slightly. Then it returned as she passed me the Co-op paper bag.

"Nice part of town. Very historic."

I took the bag and left.

I walked back more slowly than I'd gone, telling myself everything was fine. It was only a job. Five nights, 400 pounds in cash and no references required. People house-sat all the time. It wasn't complicated.

You arrived, kept the lights on and didn't break anything. That was all.

By the time I returned to the house, I had almost convinced myself.

Then I saw the man standing across from the gate.

He wasn't doing anything. He simply stood on the opposite pavement with his hands in his pockets, watching the house. He looked to be in his mid-forties, with sandy-brown hair combed back and a long face. He wore a dark waistcoat over a buttoned shirt and a brimmed cap.

I slowed. He saw me and smiled.

"You're the new sitter," he said.

It wasn't a question.

"Yes."

He stepped off the kerb and crossed towards me with one hand extended.

"Graham Sykes. I lead one of the evening ghost walks. Got a little black heritage minibus as well, for guests who can't manage the hills and steps."

I shook his hand because refusing would have felt strange.

"Callum Price."

"Good to meet you, Callum."

He released my hand and stepped back, still smiling.

"I keep an eye on a few properties for their owners. This street especially. Margaret asked me to check in and make certain you're settling down all right."

Margaret hadn't mentioned him. I didn't particularly like knowing she'd told other people I was staying there, but I only nodded.

"I'm fine."

"Good. Good."

Graham glanced at the house, then back at me.

"Beautiful property. Do you know its history?"

"Not really."

"Eighteenth century," he said. "The area was tied to the old maritime quarter. There used to be a fever hospital and a quarantine yard nearby. Foreign crews were kept there when there was fear of cholera, typhus or whatever else their ships had brought ashore."

I shifted the shopping bag into my other hand but said nothing.

"There was a Spanish merchant vessel wrecked off the coast, according to one account," Graham continued. "The survivors were held in the quarantine yard. Locals heard them calling through the walls at night. One word kept coming up in the stories. 'Mira.' Spanish for 'look.'"

He paused and watched my face.

"Cisterns were common in houses like this. They stored water for the household and sometimes supplied the sick. Sometimes they were used for other things when space ran short. Margaret mentioned the one beneath the stairs?"

"Yes. She told me not to open it."

Graham's smile widened.

"That's what she tells everyone."

"All right."

"Funny thing, though."

He leant casually against the gatepost.

"People who stay here alone always end up opening it, even when they swear they won't. There's something about the house. Gets into your thoughts."

I looked at him. He looked back, still smiling.

"I'm not opening it."

"Of course."

He pushed himself away from the post and adjusted his cap.

"Well, I'm around most evenings. I lead the sunset walk, then I'm usually back this way by 22:00. I'll check in later and make sure you're all right."

"You don't need to do that."

"No trouble. Margaret likes to know her sitters are being looked after."

He gave me a small two-fingered salute and walked away along Church Street, his hands returning to his pockets.

I stood with my shopping and watched him go.

The warning was obvious enough: cisterns, outbreaks, wreck survivors and people opening doors they shouldn't. Standard creepy local history, probably lifted straight from his ghost-walk script.

But the content wasn't what stayed with me. It was how rehearsed he had sounded. The exact pauses, the smile, the casual lean against the gatepost. As if he'd delivered that speech before, several times, and knew precisely what happened next.

That night, the house stopped pretending.

I heard it at about 21:30. I'd been sitting on the sofa, charging my phone with the new lead and eating a peanut butter sandwich, when the sound began.

It wasn't dripping this time.

It was running water. A steady flow.

I put the sandwich on the coffee table and went to the kitchen window.

The courtyard fountain was running.

Not trickling. Properly running. Water poured from the upper tier into the basin in a solid stream, catching the outdoor light and making the entire courtyard look wet and alive.

I stood there for perhaps twenty seconds, staring.

There was no visible switch for the fountain. Margaret had never mentioned one.

I had checked the courtyard twice in daylight. The fountain had been dry apart from three centimetres of standing water at the bottom, which never moved. Now it was running at full force.

I unlocked the kitchen door, left the chain fastened and opened it by about fifteen centimetres. Cold air struck my face again.

The same salt smell. The same wet sandstone flags. The water pouring into the basin wasn't clear. It was almost black, perhaps brown beneath the yellow courtyard light, and looked as though it had been stained by peat or harbour rust.

"Hello?" I called.

Nothing moved. The dark water kept pouring into the basin. It should have overflowed, but the level remained exactly the same, no matter how much flowed in.

I pulled the door shut, locked it and checked the deadbolt twice. Then I returned to the sitting room and perched on the edge of the sofa with my mobile in my hand, trying to decide whether this justified another call. PC Daniel Hargreaves had made it fairly clear that I wasn't supposed to bother anyone. And what was I going to say?

The fountain turned itself on and the water looks dodgy.

That was when the door beneath the stairs thumped.

One solid blow from the other side.

I froze, still holding my mobile, while my sandwich went stale on the table.

The thump came again, harder this time, as if someone had put their whole shoulder into it. It wasn't the house settling. It wasn't the pipes. Something was striking the door deliberately, testing it to see whether it would give.

I stood. My legs felt unsteady, but I made it into the hall and stopped about a metre from the door.

It looked normal. White paint. A brass knob set too high. There was no gap beneath it this time. It sat completely flush within its frame.

Another thump.

The door shuddered but didn't open. I looked around. One of the wooden kitchen chairs had a straight back and seemed about the right height. I fetched it, dragged it into the hall and wedged it beneath the knob at an angle.

A chair leg scraped across the tiles. The top rail caught firmly beneath the knob. Solid. Tight.

I stepped back.

For perhaps ten seconds, I felt better. In control. As though I had actually done something that mattered.

Then the chair began to move.

It didn't move quickly. The back legs dragged across the tiles a few centimetres at a time, making an awful scraping noise, while the whole chair tipped forwards as though something on the other side of the door were pulling it.

The movement was patient and deliberate. The rail slipped free of the knob, and the chair toppled sideways and clattered onto the floor.

The door remained closed, but I could feel the pressure behind it. Something was waiting there.

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

"Yes?"

"I'm leaving," I said.

My voice sounded flat. It didn't shake. I was simply finished.

There was a pause at her end, perhaps three seconds.

"All right," she said.

That was all. No argument. No questions.

"You understand that you'll only be paid if you complete the assignment," she added.

She used the same professional, detached tone in which she had told me not to open the cistern door.

"Yes," I said. "I understand."

Another pause followed, longer this time.

"Callum," she said. "Have you looked into the fountain yet?"

The question landed strangely. She wasn't asking whether I had noticed it running. She spoke as though she already knew that I had, and wanted to know whether I had taken the next step.

"What?"

"The courtyard fountain. Have you looked into it?"

I didn't answer immediately. My mind was still trying to catch up. She expected me to inspect the fountain rather than avoid it or call someone. As though looking into it were part of the job.

"No," I said.

"Mhm."

It was a small sound, almost approving.

"Well, the choice is yours."

She ended the call.

I stood there holding my mobile, staring at the overturned chair and the door that hadn't opened but wanted to. Then I went upstairs and began packing.

My rucksack was still on the bed where I had left it after my shower. I shoved in my hoodie, the new charging lead, my wallet and the remaining cereal bars from the Co-op paper bag. I didn't fold anything. I simply crammed it all inside and pulled the zip shut.

When I returned downstairs, the chair was still on its side. The door was still closed. The fountain was still running outside. I could hear it through the kitchen window, steady and wrong.

I slung the rucksack over one shoulder, went to the front door, unlocked it and pulled it open.

Church Street was empty. Completely empty. No cars. No tourists. No lights in any of the neighbouring buildings.

Except that, about ten metres to my left, across the narrow cobbled street, a small black heritage minibus stood with its interior lights on.

It was Graham Sykes's minibus, the one he used to carry people with limited mobility on his evening ghost walk. I had seen it that morning after returning from the Co-op. It was parked where anyone leaving the house would notice it immediately.

There was no driver visible. No passengers. Nothing moved inside.

Graham had said his evening route finished at about 22:00. It was only 21:15.

The minibus remained perfectly still. Its engine was off, and its lit interior was empty.

I stepped down onto the short flagged path.

Behind me, the doorbell rang.

I turned. The front door had swung shut behind me. The entrance passage beyond its distorted glass was lit by the yellow hall light I had switched on earlier.

I climbed the two steps again and leaned towards the peephole.

Someone was standing in the hall, barely half a metre from the other side of the door.

Wet. Nothing but a silhouette. No details.

It was a dark shape with water dripping from it onto the tiles. Its shoulders were hunched and its head bowed. It stood far too close to the door.

Around its edges I could make out the hall behind it: the stairs, the overturned chair. But the figure occupied the centre of the warped view, blocking almost everything else, as though it knew precisely where the peephole was and had positioned itself so that I would have to look directly at it.

The house wanted my attention turned inwards.

I stepped away. One hand remained on the door handle. Church Street and the waiting minibus were behind me.

The wet shape inside didn't move.

My mobile buzzed.

I was still on the front step with my rucksack over one shoulder, the figure waiting just inside and the empty minibus parked across the street. Margaret's name appeared on the screen.

"If you leave now, PC Hargreaves will need to file a report about the disturbance. I'd prefer not to involve him again tonight."

I read it twice.

It wasn't a request. It wasn't exactly a threat either. It was simply information, delivered in the same practical, neutral manner as the alarm code and the oyster shells. As though the decision had already been made.

I looked back at the street. The minibus was exactly where it had been, its empty interior brightly lit so that I couldn't miss it.

Hargreaves had known which house I meant the moment I mentioned Margaret Wycliffe. He had walked straight to the kitchen without asking for directions. He had gone directly to the courtyard door and checked the fountain as though he had done it before. And he had spoken about previous sitters, plural, who had rung the police.

Graham had said that people always opened the cistern. He had said it with a rehearsed smile while standing where anyone leaving the house would see him. He had told me Margaret liked her sitters to be looked after.

I stood on the step with my mobile and rucksack, while the wet figure waited just inside the door.

The police response hadn't been protection. The familiar faces nearby weren't a coincidence. They were there to keep me inside until I broke the rule.

I opened the front door, stepped back into the house and closed it behind me.

The deadbolt clicked.

I turned around.

The hall was empty. There was no wet figure and no dripping water. Only the overturned chair and the white door beneath the stairs, with its brass knob set too high.

I dropped my rucksack onto the sofa and went into the kitchen. The fountain was still running outside. I could hear through the window the steady fall of dark water that never raised the level in the basin.

I opened the drawer beside the sink and took out the Saxa table salt carton. I shook it. It was perhaps half full.

Then I returned to the hall and crouched before the door beneath the stairs.

My hand was steady when I reached for the knob. That surprised me. I had expected trembling, hesitation or some physical resistance, but my fingers simply closed around the cold brass and turned it.

Cold air poured out at once. It wasn't a draught but a flood of damp, heavy air smelling of salt and wet stone. Beneath those scents was something older, something that tightened my throat as it had the first time.

When I released the knob, the door swung inwards by itself. It opened fully and struck the inner wall with a soft thump.

Narrow brick steps descended steeply into darkness. There were perhaps twelve before they disappeared. At the bottom, I could make out black standing water, smooth and reflecting nothing.

The surface moved without any visible cause. There were no ripples, only slow, broad rolls, as though something large had turned beneath it and the motion was still travelling upwards.

I switched on my mobile's torch. The beam cut through the darkness and reached the far wall.

Oyster shells had been set into the mortar in a rough ring nearly a metre across. They were old and grey-white, their edges worn smooth, packed tightly into the brick with their ridged backs facing outwards.

They matched the shells Margaret had given me exactly. The same size, the same arrangement. It looked as though someone had pressed them into wet mortar one at a time, an old seafarers' ward intended either to seal something in or keep something out.

The water shifted again, closer this time.

I heard it before I saw anything: a wet sliding noise, followed by a rapid Spanish voice, close and insistent. The words ran together too quickly for me to separate them, but I remembered Graham's story about survivors from a wrecked Spanish merchant vessel being held at the old maritime quarantine yard.

The tone needed no translation. It wanted an acknowledgement.

It wanted me to look down, meet its eyes and see it fully so that it could see me.

I kept my gaze fixed on the ring of shells. My grip tightened around the salt carton. The voice continued, rising slightly, until I caught one word I recognised.

"Mira."

Look.

I didn't.

I opened the spout and poured a thick line of salt along the lower edge of the shell ring, moving slowly from left to right. The salt hissed when it struck the wet brick. I kept pouring until I had closed the break and reinforced the circle, sealing the boundary as though repairing a gap in a fence.

The water surged.

I saw it only at the edge of my vision: a sudden upward rush of black water climbing the steps three at a time. Pale shapes slid beneath the surface, long and smooth. They turned as though searching rather than swimming, moving deliberately, hunting for my face.

I backed away without looking down.

My heel struck the hall tiles. I seized the door with my free hand and slammed it shut.

The house shuddered.

Not merely the door. The entire structure. The walls, floor and beams overhead flexed inwards for half a second, as though the building had drawn breath.

Then I heard the footsteps.

They were wet and fast, slapping across the tiles from the kitchen and the courtyard door, coming towards me with the same deliberate rhythm I had heard on the stairs the previous night.

I froze with my back against the opposite wall, the salt carton still in my hand.

The footsteps entered the hall. I could see the tiles darkening where they fell, wet prints appearing one after another and advancing directly towards me.

They stopped at the oyster-shell line I had laid across the kitchen threshold earlier.

The pressure in the air eased. It didn't vanish, but withdrew slightly, like something testing the boundary and finding it firm.

The footsteps retreated. Slowly. Without hurry. They moved back towards the kitchen and the courtyard, fading into the sound of the fountain still running outside.

The dripping ceased.

I remained against the wall, clutching the salt while my mobile's torch shone at nothing. My heart beat unevenly in my chest.

I counted to sixty. Then I counted to sixty again.

Nothing moved.

The door beneath the stairs remained shut. The air grew warmer by a couple of degrees.

I went into the kitchen and looked through the window.

The courtyard was dry. The fountain stood in the centre with about three centimetres of perfectly still water at the bottom.

I returned to the sofa, sat down and didn't move until the sky began to lighten.

Morning arrived with a deliberate sort of neatness.

The chain on the kitchen door was still fastened. I checked it twice. It was secure and positioned exactly as I had left it, perhaps even straighter.

The chair I had wedged beneath the cistern door's knob was back in the kitchen, pushed beneath the table at a perfect right angle, as though someone had positioned it with a ruler.

The line of oyster shells across the threshold had vanished. They hadn't been scattered or kicked aside. The floor had been swept clean.

The Co-op paper bag beside my mobile was full again.

I opened it. Inside were cleaned oyster shells, the same number Margaret had given me on the first night, carrying the same faint smell of bleach.

I stood holding the bag for perhaps thirty seconds. Then I put it down and walked away.

My mobile buzzed at 07:38. Margaret's message was brief and professional.

"The cash is in the kitchen drawer beside the sink. Leave the key on the counter. Make sure the front door is secure when you go. Thank you."

I opened the drawer. Four hundred pounds in twenty-pound notes, folded once and secured with an elastic band.

I took the money. I left the key on the counter beside the index card bearing the Wi-Fi password. Then I collected my rucksack, entered 4826 into the alarm and stepped outside, making sure the front door had latched behind me.

Church Street was normal again.

Tourists walked past carrying takeaway coffees. A man was unloading boxes from a van two houses away. There was no heritage minibus and no sign of Graham Sykes.

I didn't ring Hargreaves. I didn't go looking for Graham to ask what the hell his empty minibus had been doing across the street. I walked to my silver Skoda Fabia, threw my rucksack onto the passenger seat and left Whitby, taking the A171 westbound towards Guisborough before joining the A174. I kept the window cracked and the radio off.

I carried what I had learnt with me.

Curiosity created access. That was what the house had wanted. That was what Margaret had been waiting for. Someone to look. Someone to open the door. Someone to meet the eyes of whatever waited in the water.

Attention could serve as an invitation. Eye contact could become permission.

After that, I stopped looking into dark water at night. I stopped checking windows whenever I felt watched.

When I reached my rented flat roughly two hours later, with four hundred pounds in cash in my pocket and my mobile charged to 67 per cent, I didn't talk about the house, the cistern or the wet shapes that had climbed the steps searching for my face.

I simply paid my rent.

That was it.
