The Cabin Above Kielder Water

I was three days from a flight from Newcastle to Belfast and two days from a contract deadline when an NHS foundation trust's identity-management and controlled-medicine access logs corrupted themselves into digital soup during an archive migration. That was what happened when you underfunded IT for five years and then acted surprised when ransomware groups began circling. It was not my problem, except that it was, because I had signed the contract and they were paying me enough to cover two months' rent. Missing the deadline would also destroy the referral network I had spent four years building.

The work itself was not complicated. Reconstruct the access-control records, cross-reference them against surviving archive fragments, patch the gaps where I could and document the gaps where I could not. I had no unrestricted access to live patient data, nor did I want it. My job was to produce a coherent, defensible record for the trust's information-governance auditors.

It was tedious work. The sort you did with coffee, reliable broadband and perhaps some background noise that was not actively hostile to concentration. I had been moving between cafes for seventy-two hours.

Newcastle upon Tyne first, then west to Hexham, north through Bellingham, anywhere with Wi-Fi and a table. Cafe Wi-Fi across Northumberland and the Borders occupied a sweet spot: just good enough to load a web page, but just poor enough to drop a VPN connection every eleven minutes. I had a mobile hotspot, but it crawled whenever I tried to pull anything larger than a text file from the trust's archive server. The Costa in Newcastle had been tolerable until a parent-and-toddler group occupied several tables and the children began throwing paper serviettes at the ceiling.

I lasted an hour. I moved to an independent cafe called The Copper Kettle in Bellingham, which played folk-rock loudly enough to make my teeth ache. Forty-five minutes there. Then a roadside transport cafe beside the A68, which had exactly one socket and it was behind the till.

That meant sitting at the counter while the manager watched YouTube videos on his mobile without headphones. By the third day, I had started searching for anything else. Hotels were too expensive, and most had the same overloaded-router problem. I needed isolation.

I needed somewhere I would not be competing with fifteen other people for bandwidth, and where nobody would start a conversation about whether I was visiting family or merely passing through. That was when I found the listing: a cottage near Kielder village and Kielder Water on a holiday-let platform. The photographs were poor, which honestly made the place feel more legitimate.

A lot of fraudulent listings used stolen photographs from luxury properties, all carefully staged and warmly lit. These looked as though the owner had taken them on an old mobile. There were dim interior shots, a grainy view of trees and a kitchen worktop holding something that might have been a coffee machine or a toaster. It was difficult to tell. But the description promised fibre broadband.

It specifically said fibre, not copper, mobile broadband or satellite. It also offered self check-in, which meant I would not have to make small talk with an owner who wanted to spend twenty minutes explaining the property's quirks. The price was GBP 48 per night. That bothered me slightly.

GBP 48 for an entire cottage with fibre broadband felt implausibly low. Kielder village was not exactly central London, but it sat beside Kielder Water, and comparable cottages generally cost roughly GBP 85 to GBP 160 per night. I decided it might be a new listing.

Perhaps the owner was trying to build reviews. Perhaps the photographs were poor enough that most people simply scrolled past. I read the three reviews. Two were short and generic, the kind that said, "Nice place, very quiet."

Nothing else. The third had been posted four months earlier and said the Wi-Fi was excellent and the owner had left them alone. That was enough for me. I booked two nights.

The confirmation was instant. The check-in instructions arrived immediately. There was a lockbox beside the front door, and the code was the last four digits of my mobile number.

Easy. I packed up at the transport cafe, put my laptop bag in the hire Vauxhall Astra and began driving north. The route followed the A68 and A696 corridor before the B6320 towards Kielder. The roads were fast in places, empty in others, running between moorland, fields and dark ranks of forestry.

I had driven much of the route before for other contracts. It was the sort of journey on which you forgot you were moving until you glanced at the odometer. The sun was dropping when the sat-nav took me off the main road.

It was not quite dusk, but it was close. The light had become orange and thin. I passed through what little there was of Kielder village centre: a village post office, an outdoor-supplies shop and a petrol station that looked closed.

Then the sat-nav told me to turn on to Bakethin Road. I did. The road narrowed. There was tarmac at first, then the sat-nav directed me on to an unclassified Forestry England track identified on its map as Forest Track 17.

That was when things began to feel wrong. The tarmac ended and loose, pale gravel started. My mobile signal dropped from two bars to one and then vanished.

I glanced at the screen. No service. The sat-nav was still working from its cached map, but the blue marker showing my position had stopped moving smoothly. It jumped every few seconds.

I carried on. The track curved uphill between conifers that were taller and closer than I had expected. The Astra was perfectly adequate on ordinary roads, but it was not built for this. Branches scraped against the wing mirrors.

The radio had been carrying a classic-rock station from Newcastle. It began breaking up, bursts of static cutting through the guitars, until there was only static and then nothing. I switched it off. The gravel became rougher.

I slowed to about fifteen miles per hour and watched for potholes. The sat-nav said I had another mile and a half to go. The track did not appear to have been maintained recently. Weeds grew along its centre.

There were several deep ruts that I had to take at an angle. I passed a faded Forestry England sign mentioning the fire-risk level, but could not read the rest. The trees began to open on my right.

Through the trunks I caught a glimpse of water, dark and smooth. Kielder Water, probably, or one of its inlets. The listing had mentioned access to the reservoir, but I had barely noticed that part.

The sat-nav said I was close. Sixty metres, then thirty. Then I saw it. The cottage stood above the track on a small rise between two enormous conifers.

A gravel drive curved up to a flat parking area. I pulled in and switched off the engine. For a moment, I simply sat there. The cottage looked far better than it had in the photographs.

That was the first thing I noticed. The photographs had made it look dim and cramped, but it had a proper front porch with railings that appeared new. The timber cladding was clean and stained a deep reddish brown. Large windows stood on either side of the door.

The light was disappearing quickly, but I could see enough to know this was not a GBP 48-a-night property. It belonged closer to the top of the usual range. I took my laptop bag from the passenger seat, then opened the boot and lifted out my duffel. Inside it, beneath my clothes, was the small repair case I carried on longer jobs: a compact set of screwdrivers, pliers, a 10 mm spanner, spare leads and silver gaffer tape. I had started carrying it after too many nights in cheap accommodation with loose sockets and broken desk lamps.

The air smelt of pine and cold water. It was quiet. Not the sort of quiet that descended on a cafe when people stopped talking, but the sort in which there was nothing to hear.

No traffic. No voices. Only trees and distance. I walked up to the porch. The lockbox was exactly where the instructions said it would be, hanging beside the front door.

I entered the last four digits of my mobile number and it clicked open. The key was inside. I unlocked the door and stepped through.

The cottage was nicer inside as well. It had wooden floors, a small kitchen to the left and appliances that were not ancient. A sofa and an armchair faced a window that probably offered a fine view of the reservoir by day. A table beside the kitchen would suit my equipment. I tried the light switch.

The ceiling light came on, warm and steady. Everything looked fine. Better than fine. That was the problem: it looked too good. I closed the door and examined the room more carefully.

A stone fireplace occupied the far wall. Real stone, not imitation panels. Large windows stood on either side of it, showing trees and, if the light had lasted a little longer, perhaps the water below.

The sofa and chair were respectable, neither new nor sagging. The router caught my attention first. It sat on an open shelf beside the fireplace, its green and white lights blinking in a steady pattern. That was promising.

I had encountered enough dubious rural installations to know that a router left in the open usually meant somebody had actually considered coverage, rather than hiding it in a cupboard and hoping for the best. I put my duffel near the door, dropped the laptop bag on the table and opened it. The table was solid wood and broad enough for me to spread out. I took out my laptop, charger, external drive, the USB hub I had carried for three years and the notebook in which I kept my task lists.

Physical lists. I knew it was unfashionable, but I liked crossing off work with an actual pen. I connected everything and opened the laptop. The screen returned to the trust VPN login I had left open at the transport cafe.

I had about forty access-log batches left to cross-reference. Then I could move to the archive fragments. After that came gap reconstruction and documentation. The documentation always took longer than I expected.

I opened the available Wi-Fi networks and found the cottage's SSID. It was called Kielder View Guest. There was no password, which was appalling security, but with a deadline looming I was in no mood to complain. I connected and waited for a sign-in portal.

There was none. I went straight online. I opened a browser and loaded a news site. It appeared immediately.

Perhaps the place was genuine after all. I ran a speed test. The little dial turned and the numbers climbed. Download speed was 212 megabits per second.

Upload was 94. Ping was 18 milliseconds. That was better than the broadband in my Leeds flat. I leant back, looked at the router and then surveyed the cottage again.

Someone had spent serious money here. The wooden floors were properly finished and spotless. The kitchen appliances looked perhaps five years old rather than twenty.

The windows were well sealed. The warmth remained steady even as the air outside cooled. GBP 48 per night still made no sense, but I was hardly going to contact the owner and ask her to charge more.

I decided it was a soft launch, or that she was undercutting the market to gather reviews. I had seen that before. I opened my task list and began work.

The logs were a disaster. That was what happened when an archive migration corrupted data halfway through. There were partial entries, timestamps that did not align and user identifiers referring to accounts nobody could locate. My job was to turn the wreckage into something coherent enough for the trust to demonstrate to its information-governance auditors that critical access-control records had not simply vanished.

I opened the first batch and cross-referenced it against the surviving fragments. I matched a user identifier, recorded it and moved on. I matched a timestamp and logged it. I found a gap, documented it and continued.

The work was dull and methodical. I liked it. I completed twenty batches, then thirty. The VPN remained stable.

The connection did not drop. I did not have to move closer to the router or restart anything. It simply worked. That almost never happened.

At about 19:00, I stopped to eat a petrol-station cereal bar I had bought in Bellingham. It tasted like chocolate-flavoured cardboard. I washed it down with water from a bottle in my bag and returned to work. By 19:45, I had cleared thirty-eight batches.

I was ahead of schedule. At that pace, I could finish the cross-referencing that night and begin the archive fragments the following morning. I would be a full day ahead of the deadline and might even sleep before my flight.

I opened the next file and began transferring it from the external drive to the laptop. It was large, about 600 megabytes. The progress indicator crept forward. Ten per cent, twenty, thirty.

I leant back and stretched. My neck was stiff. I rolled my shoulders and looked out of the window. It was fully dark.

I could no longer see the reservoir, only the reflection of the cottage interior in the glass. The transfer reached forty-two per cent and stopped. I waited. Transfers sometimes paused while the system cached data.

I counted to ten. Still forty-two per cent. I moved the mouse. The cursor responded normally.

I switched to the browser and tried to reload the news site. Nothing. The loading circle spun without end. I checked the Wi-Fi icon.

I was still connected to Kielder View Guest with full signal. I opened a terminal and pinged Google's DNS service. The connection timed out.

Wonderful. I cancelled the transfer and tried to reconnect to the VPN. It hung on "Establishing secure connection" for thirty seconds, then failed. I went to the router.

Its lights were still blinking green and white in the same pattern as before. I unplugged it, counted to ten and plugged it back in. The lights went dark, then cycled through their start-up sequence. I waited.

Two minutes later, they settled into the same green-and-white pattern. I returned to the laptop and repeated the ping test. The connection timed out. I checked my mobile.

There was still no signal, not even one bar. I stood looking at the router and tried to understand the fault. Its lights appeared normal. The local connection was active, but nothing was passing through it.

Then every light went out. The ceiling light, the lamp beside the sofa, the glow from the kitchen, all of them. I did not move.

I stood in darkness and waited for my eyes to adjust. I assumed it was the consumer unit or perhaps the local supply. Rural areas suffered power cuts when branches hit overhead lines. I counted to twenty.

The lights returned, but they were wrong. They were dimmer and flickered, not like a loose bulb but as though the current itself were unstable. I crossed to the kitchen and switched the overhead light off, then on. It responded, but remained dim, faltering every few seconds.

That was not a tripped circuit. Something was wrong with the incoming supply. I took out my mobile and switched on its torch, although the lights were still burning. I no longer trusted them.

I opened the front door and stepped on to the porch. The cold struck first. I should have fetched a jumper. Then I noticed the smell.

It was metallic and sharp, like wet coins or blood, but not quite either. I had smelt something similar during a secondary-school science lesson when we touched the terminals of a 9-volt battery to wire wool. Ozone, perhaps, or scorched metal. I swept the mobile's light across the porch and towards the drive.

The Astra was still there. The trees looked unchanged. I could see no fallen branches and no obvious storm damage.

I turned and shone the light towards the roofline, where the electricity cable entered the cottage. It took a moment to understand what I was seeing. The cable had been split open. It had not been cut.

It had been peeled. The rubber sheath hung in strips and the exposed wires had been pulled apart. Several still gave off weak sparks.

I stepped down from the porch and moved closer, keeping the light steady. There were gouges in the timber cladding beside the cable. Long scratches, deep enough to expose pale wood beneath the stain, ran in four parallel lines.

Perhaps five. A branch had not made those marks. Branches did not leave grooves that clean. I lowered the light and saw a sheet of paper.

It had been folded in half and pinned beneath a loose section of cable where it hung against the wall. White, ordinary 80 gsm A4 printer paper. I reached up and pulled it free.

The cable shifted and sparked. I jumped back. The paper felt cold and slightly damp. I returned indoors and locked the door.

The lights were still flickering. I ignored them and went to the kitchen table, placing my mobile torch-upwards so its beam illuminated the room. I unfolded the paper. The text was printed in black ink, in an ordinary serif font with double-spaced lines. The first sentence was bold.

You were supposed to read this before dark.

I stared at it. Then I read it again.

You were supposed to read this before dark.

Helpful information, delivered after the event. The next paragraph began immediately beneath it.

This cottage was a Forestry Commission emergency shelter until 1949. Before that, it was a forester's lodge. Before that, it was the forestry works manager's cottage, built in 1888. The construction and filling of Kielder Reservoir submerged the old valley, its farms and tracks, and the entrances to a network of caves during 1980-1982. The Forestry Commission kept this cottage because it stood high enough. Elevation matters.

What's down there cannot easily climb beyond a certain height.

I stopped and examined the sheet. Ordinary A4, slightly damp from the air outside. The printing was crisp, probably from a laser printer. Somebody had taken the trouble to type this, print it and pin it beneath a deliberately damaged power cable.

I continued.

Geological survey parties entered those caves twice before the valley was flooded, in 1867 and 1935. Both reported evidence of habitation, but neither found inhabitants. There were objects left behind. Tools, or things resembling tools. Arrangements of stone.

The 1935 survey recorded unexplained variations in smell and temperature and recommended sealing the entrances before any future reservoir works. That did not happen. There was no budget.

When the old valley was flooded, the caves flooded with it. Something was still inside them. It still is.

I lowered the sheet and rubbed my eyes.

This was either an elaborate prank or somebody's creative-writing project, left behind to frighten guests with a local legend. Presumably the same person had damaged the power cable to make it convincing. Except the gouges in the cladding were real.

The exposed wires were real. I raised the paper again.

It needs somebody to arrive alone once each year. Not every week. Not every month. Once. I don't know why. I don't know what it does for the rest of the year.

I only know that when one person comes alone to this cottage and stays the night, it climbs up, completes whatever it needs to complete and returns below. If nobody comes, it ranges farther. Two years ago, a buyer took possession of the property intending to renovate and resell it, and it was not listed for four months. During that period, two walkers and a forestry worker disappeared from the northern forest trails. An unmanned fishing boat was found drifting on the reservoir.

When I began listing the cottage again, that stopped.

I read the paragraph three times. The listing. The owner.

Helen Crowther. That was the name on the holiday-let account. She knew. She had knowingly attracted me here.

The next heading was bold and larger than the rest.

RULES

Of course there were rules.

1. Keep one exterior light on at all times after sunset. If the power dips, reset the main switch at the consumer unit in the underfloor void. The service hatch is beside the laundry alcove. There is a head torch in the top kitchen drawer.

I glanced towards the kitchen but did not move.

2. Do not look into the pond after sunset. It lies about 12 metres west of the cottage. You may have seen it while driving up. In daylight it is safe. After dark, do not look at it and do not approach it. The pond is connected below ground to the drowned caves.

If you hear anything that appears to come from that direction, ignore it.

I did not remember seeing a pond. I might have passed it without noticing. It was impossible to tell now.

3. If you hear a single tap on a wall or door, answer with exactly one tap, then remain silent. Do not speak. Do not ask questions. One tap, one response. Nothing more.

The back of my neck felt cold. The room itself was warm, but my neck was cold.

4. From 22:30 until 23:30, it will circle the cottage. You will hear it. You may see movement beyond the windows. Do not acknowledge it. Do not attempt to follow its position. Sit somewhere central, away from exterior walls, and wait until it has completed its circuit.

I checked my mobile. It was 20:03. Two hours and twenty-seven minutes remained.

5. After midnight, it can enter through any gap wider than two fingers. Inspect all doors and windows, the service hatch, vents and every other opening. The ventilation grilles are meshed, but check that the mesh is secure. Weatherstrip and silver gaffer tape are stored in the laundry alcove. The chimney flue is already sealed.

I looked at the front door. It was closed and locked. The windows appeared sound from where I stood, but I had not examined them.

6. Do not attempt to leave before sunrise at 06:42. If you go outside, enter your car or try to walk or drive away, it will know. It will hurry. You will not reach the main road.

The final lines were bold and underlined.

Stay inside. Follow the rules. You will be safe in the morning.

Further instructions are enclosed in the separately folded insert. Read them now. Keep them away from the hearth.

There was no signature, only the instructions and that promise. A smaller folded sheet had been tucked inside the main rules page. I opened it far enough to see another block of printed text, then crumpled it in sudden anger and threw it towards the fireplace. It landed on the stone just short of the cold-looking hearth.

I retained the main rules sheet in my hand.

The cottage had not changed. The same sofa and chair stood before the same fireplace. The router was still blinking. My laptop remained open on the table, showing the frozen transfer and dead VPN connection.

It was a prank. It had to be. Somebody with a warped sense of humour and too much time had decided to frighten holiday-let guests. They had damaged the power cable, printed a sinister story and probably hidden a camera somewhere to record reactions for an online prank video. I would find it in the morning, complain to the platform, demand a refund and have Helen Crowther removed.

That was reasonable. Logical. But the gouges did not resemble tool marks.

They were irregular in a way that looked organic. The cable had been peeled rather than cut, as if something strong enough to split rubber sheathing lengthways had simply gripped it. I folded the main rules sheet and put it in my pocket.

I took my mobile. Its torch was still on, the beam pointing at the ceiling. I would leave. I would drive back to Kielder village, find somewhere with a working socket and normal broadband, and finish the contract there.

I did not need this. I had thirty-eight hours until my flight and perhaps fifty hours of work remaining if I stayed focused. There was no room in that schedule for elaborate pranks. I unlocked the door and stepped outside.

The porch was still cold. The metallic smell lingered, fainter now but unmistakable. I swept the torch beam across the drive. The Astra stood where I had left it, driver's side towards the cottage and boot towards the trees.

I walked down the steps and across the gravel. The driver's door opened normally. I leant inside and pulled the bonnet release.

The bonnet opened with the usual click. I went round to the front, lifted it and secured it with the support rod. Then I aimed my mobile into the engine compartment. The battery was still there.

That was something. But neither cable remained connected. The positive lead had been pulled free and twisted around the air-intake duct.

The negative lead had been threaded through the gap between the engine block and frame, looped twice and tucked beneath itself. It was not cut or visibly damaged. It had simply been removed and repositioned with deliberate care.

I stared at it for perhaps twenty seconds. This was not an accident. Battery cables did not detach themselves. Ordinarily, you needed a 10 mm spanner to loosen the clamps.

These leads had not merely been loosened. They appeared to have been gripped, twisted and threaded through the engine as though somebody had taken their time. I tried to pull the negative lead free. It was tight.

Very tight. Its rubber coating was crushed where it passed through the gap, and it did not move when I pulled. I needed tools. Fortunately, the repair case was in my duffel, but it was inside the cottage, and even with the spanner and pliers I was not certain I could undo whatever had been done.

I pressed the lock button on the key fob. The powerless car did not respond. I pressed unlock and then the boot release. The red light on the fob blinked each time, but there was no click from the locks and no flash from the lamps.

I leant into the driver's seat and tried the ignition anyway. Nothing happened. There was not even a click.

The car was completely dead. With both battery leads disconnected, that was precisely what it ought to be. I closed the driver's door and walked slowly around the Astra, inspecting it. There were no scratches, dents or broken windows.

The tyres appeared intact. Nothing else was visibly damaged. Whoever had done this understood exactly what was required: open the bonnet from inside, disconnect the leads, thread them through the engine so they could not be quickly replaced, then leave a car that appeared untouched but would not start.

I lowered the bonnet and let it drop. It latched with a solid thud. Then I stood beside the car with my mobile's beam falling across the gravel and listened.

There were trees, wind moving in branches and water somewhere in the distance. Perhaps the reservoir. Perhaps the pond mentioned in the rules. There were no voices, footsteps or engines on the track. I was a long way from Kielder village, on a forestry track that barely qualified as driveable. I had no mobile signal and no working car. Walking out before morning would mean breaking the clearest rule on the page.

"It will hurry. You will not reach the main road."

I looked at the cottage. Its lights still flickered, dim and unstable. The damaged power cable hung from the roofline, stripped and occasionally sparking.

I considered the specificity of the rules. Keep an exterior light burning. Reset the consumer unit if necessary. Do not look into the pond. Answer one tap with one tap. It would circle from 22:30 to 23:30. After midnight, it could enter through any opening wider than two fingers.

Someone had written those rules because they had been tested. Because Helen Crowther, or whoever actually owned the cottage, had done this before and knew what might keep a victim alive until morning.

I remained beside the disabled car for another thirty seconds, trying to find an option I had overlooked. There was no signal. The repair tools might help with the battery leads, but even if I restored them, the rules claimed I would not reach the main road. Then I remembered that the bottom of the sheet listed the owner's number.

I pulled the rules from my pocket and checked. Helen Crowther. Beneath her name, in the same serif typeface, was a British mobile number.

It was worth trying. I entered the number and pressed call. I did not expect it to connect. There were no signal bars and the screen still said there was no service, yet it displayed "Calling", and then the call went through.

One ring. Two.

Someone answered. I waited for a voice, but heard only breathing. Slow and steady. In and out. It was not strained or laboured. It was simply there.

"Hello?" I said.

The breathing continued at exactly the same rhythm and depth.

"Helen, I'm Daniel Mercer. I booked the cottage for tonight and..."

Nothing. Only that regular inhalation and exhalation, quiet enough that I had to press the mobile closer to my ear to be certain the call had not dropped.

"I don't know what's happening here, but the electricity cable has been damaged and my hire car has been disabled. I need an explanation."

In. Out. In. Out.

My stomach tightened. This was neither a poor connection nor an accidental call. Somebody was listening.

"If this is part of a prank, it isn't funny. I have work to finish and a flight in two days. I don't have time for..."

The call ended.

There was no warning tone and no fading signal. One moment I heard breathing; the next there was silence, and the screen displayed "Call ended" with a duration of one minute and eighteen seconds. I tried again. "Calling" remained on the screen for about five seconds before being replaced by "No connection available."

The signal indicator was still empty. Yet the first call had connected cleanly. It made no sense. Mobile networks did not usually grant a single perfect call in a dead zone and then vanish as though somebody had closed a door.

I stared at the mobile as if it might explain itself. It did not.

Only then did I return to the cottage. I climbed the porch steps, went inside once and locked the door behind me.

The lights continued to flicker with the same irregular dimming and brightening that hurt my eyes if I watched for too long. I took the main rules sheet from my pocket and read it again from the beginning, no longer searching for plot holes or evidence of a prank. I was looking for instructions I might have missed.

Further instructions are enclosed in the separately folded insert. Read them now. Keep them away from the hearth.

The insert.

I turned towards the fireplace. The crumpled paper was no longer lying where I had thrown it.

I crossed the room, passing the laptop where the dead transfer still showed forty-two per cent. The stone fireplace looked clean. There were no logs or kindling and no sign that anybody had used it recently. Its interior appeared cold.

I crouched and shone my mobile into the opening. Old soot crusted the rear stones. A few charred fragments of wood lay in the ash, perhaps months or years old. Near the front was a fresh black curl of paper.

I reached for it, but it collapsed at the touch of my finger. A thin red ember glowed beneath it for an instant, although the hearth had looked cold, then faded to black.

I searched the ash and ran my hand along the inner edge, but nothing legible remained. The separate folded insert had been consumed. The main rules sheet was still intact in my hand.

I had already made a serious mistake. The insert might have explained what I was meant to do between now and sunrise. It might have contained the difference between surviving and not surviving.

I had destroyed it because I was angry. Not deliberately, not with any understanding of what the hearth concealed, but through carelessness all the same.

I stood, folded the main sheet slowly and returned it to my pocket. My hands felt cold. The room felt colder. The lights dimmed again, then strengthened.

The rules said that if the power dipped, I should reset the main switch at the consumer unit in the underfloor void. The service hatch was beside the laundry alcove. A head torch was in the top kitchen drawer.

I opened the drawer beside the sink. Inside lay a cheap head torch with an elastic strap, the sort an ironmonger's might sell for GBP 8. I switched it on.

Its LED gave a bright, narrow beam, much better than the torch on my mobile. I pulled it over my head and adjusted the strap. Then I fetched the small repair case from my duffel and carried it with me towards the back of the cottage, past the bathroom and a cupboard.

A stacked washing machine and tumble dryer stood in a shallow alcove, both white and much newer than I had expected. Beside them was a roll of weatherstrip and two rolls of silver gaffer tape. Set into the floor behind the machines was a square wooden service hatch, about sixty centimetres across, with a recessed metal ring for a handle.

I took the ring and pulled. The hatch rose with a creak on old hinges. A smell struck me immediately.

Rot. Damp earth. Something sour and organic, like a cellar in which water had stood for too long. I leant over the opening and directed the head torch downwards.

A wooden ladder descended into darkness. The walls below were bare earth and stone. The air seemed thick. I did not want to climb down.

But the lights were still flickering, and the rules told me to reset the consumer unit. I had few alternatives. I left the repair case beside the hatch, turned round, placed my feet on the ladder and began descending. Each rung felt solid, but the timber was old and damp, and I did not trust it.

I kept my weight centred and moved carefully. The smell worsened as I descended: rot, wet soil and something else.

Something metallic.

It was the same smell that had hung around the peeled power cable outside.

I reached the bottom. The underfloor void was roughly a metre and a half high, enough room to crouch but not to stand. Its floor was packed earth.

The beam of my head torch passed over support timbers, old pipes and a section of ducting that looked as though nobody had touched it in decades. The ventilation openings were covered by metal mesh, as the rules had promised, although I would need to check each fixing before midnight.

On the far wall hung a grey metal consumer unit. I moved towards it in a crouch, keeping one hand on a support beam for balance. The earth beneath my shoes was soft and damp.

I did not want to think about what had made it that way.

Beside the consumer unit, on a wooden shelf, stood a VHF marine set. The sort used on boats. It was boxy and black, with a coiled handset and a small LED display on the front, conspicuously out of place beneath a cottage above Kielder Water.

A yellow sticky note had been fixed to the top. I leaned closer to read it.

"CHANNEL 16 ONLY."

That was all. No explanation. Just those three words, handwritten in blue ink.

I looked at the radio. Its screen was dark. There was no power indicator, no light of any kind.

I reached towards the consumer unit, intending to reset whatever had tripped, when the radio clicked. It was not loud, merely the soft mechanical sound of a relay engaging.

The screen lit with a green backlight. The display showed CH 16 in blocky digital characters.

I had not touched it.

Static hissed from the speaker, low and steady. Then a man's voice cut through, calm and official.

"Northumbria Police response unit to occupied property. Do you receive?"

I stared at the radio. My hand was still hovering near the consumer unit.

The voice continued. "Welfare check triggered by your booking. Sat-nav lost the track roughly a quarter of a mile back, but I can see your exterior light from here. Approaching on foot now."

There was a pause and another burst of static.

"This is PC Callum Price. If you can hear me, stay inside. I'll be at your door in two minutes."

I did not move. I hardly breathed.

The exterior light I had seen flickering earlier was still on. Barely. Its glow was dim and unstable, but it would have been visible to anyone walking up to the cottage.

Then, as if the thought had triggered it, there was a soft pop overhead, the sound a bulb makes when its filament blows.

The exterior light went out.

The underfloor void became silent. It was not peaceful silence, not the sort that lets you relax and realise how much tension you have been carrying. It was the opposite. Every sound I made seemed too loud, and I became conscious of my own breathing.

Every inhalation. Every exhalation.

My GBP 8 head torch gave off a faint electrical hum I had never noticed before. Above me, the cottage floor creaked under its own weight as the timbers settled, but in that silence it sounded deliberate.

The marine set remained on the shelf, its green screen displaying Channel 16. The static had stopped completely after the officer's final transmission. There was no hiss and no background noise, only the glowing display.

I lowered my hand from the consumer unit. My palm was wet with sweat.

Something heavy shifted outside.

They were not footsteps. It sounded more like weight being redistributed: a deer rising from the ground, or a sheet of wet leaves settling as it was dragged over grass. There was a soft compression of earth, followed by a low scrape.

It came from the direction of the pond.

About 12 metres west of the cottage, the rules had said.

Do not look into it after sundown.

Do not go near it.

Do not acknowledge sounds from that direction.

I stood perfectly still. The exterior light was dead. I had heard it fail less than a minute earlier.

If PC Price truly was walking towards the cottage, he would now see a dark building with nothing to guide him. That felt wrong.

Everything felt wrong.

A single tap struck the front window.

Not a knock. A tap. Controlled and measured, as if someone were testing the glass with one knuckle.

I froze.

Rule three had been explicit. If you hear a single tap on a wall or door, tap once in reply, then remain silent. Do not speak. Do not ask questions.

But the sound had come from a window, not a wall or door. Did that count? Was the wording exact, or did it cover every part of the cottage?

I did not know. The main rules sheet was still folded in my pocket, but I had crumpled the separate insert and thrown it towards the cold-looking hearth. A concealed ember had consumed it before I could retrieve it. Whatever extra guidance it had contained was gone.

The tap came again. The same window. The same single, careful strike.

I reached out and tapped the nearest support beam once with my knuckles. The sound was dull, absorbed by old wood and packed earth, but it was unmistakably a tap.

One tap in reply.

I held my breath.

Above me, the porch boards creaked. Not the random complaint of settling timber, but the sound of weight moving slowly across old wood.

One step, then another, leading away from the front window and towards the side of the cottage.

It had heard me. It had accepted the response. It was moving on.

I exhaled slowly and silently.

The tapping began again at a different window, this time on the east side of the cottage, beside the table where I had been working.

The same solitary tap. The same measured rhythm.

I tapped the beam once.

The porch boards creaked again as the weight moved farther around the building, towards the rear, where the laundry alcove stood above me and the bathroom window faced the trees.

Another tap struck the rear window.

I tapped once on the beam.

The footsteps continued their circuit. Steady and methodical. Neither fast nor slow. Merely consistent.

Tap.

A front window on the opposite side this time.

I tapped back.

Tap.

A side window again, but at another point.

I answered once.

It was mapping me. That was how it felt. Each time I replied, it learnt where I was. Perhaps it was learning the layout, testing the walls or confirming that I would obey the rules.

I remained where I was. I did not move towards the ladder or try to climb back into the cottage.

The rules had instructed me to sit somewhere central during the circling period, away from exterior walls. The underfloor void did not have exterior walls in quite the same way. I was beneath the centre of the building.

Technically, I was central. I did not know whether that logic would protect me.

The tapping stopped.

The footsteps stopped with it.

I waited and counted to thirty in my head.

Nothing.

Then I heard an engine.

It was not starting. It was already running, but roughly, struggling and misfiring. The noise came from down the hill, beyond my powerless Vauxhall Astra with its disconnected battery.

It sounded like a vehicle that had been standing too long, its fuel system clogged, labouring as it ground up the gravel track.

I tilted my head and listened. No headlights swept through the cracks between the floorboards. No beams cut through the trees.

The engine noise drew closer, then stalled. It choked, coughed once and died.

Silence returned.

I heard a vehicle door open with a metallic click and creak, then close again with a solid thud.

Real.

Boots crunched over gravel. Heavy tread. Confident steps.

A torch beam swept across the porch above me. I saw its light moving through the gaps in the floorboards from left to right, steady and purposeful.

"Daniel Mercer?"

The voice was clear, male and calm, with the same official tone I had heard through the marine set.

"PC Callum Price, Northumbria Police. I'm here to conduct a welfare check. Your holiday-let owner reported concerns about the property."

I did not move or answer.

The boots crossed the porch towards the front door. I could hear each deliberate step.

"I saw your car down the track. I know you're inside. I only need to make sure you're all right."

His manner was controlled, neither aggressive nor suspicious. He sounded like a police officer doing an ordinary job.

I almost moved towards the ladder. I almost climbed up to unlock the door and let him in.

Then I stopped.

The rules said not to leave before sunrise. They had said nothing about allowing someone else inside.

But the marine set had carried his transmission before I heard the engine approaching. Radios did not predict the future. Either it had captured something PC Price had transmitted earlier, before he reached the property, or it was replaying something that had already happened to him. The second possibility was worse.

I remained where I was.

"Mr Mercer, I'm going to need you to open the door."

The voice was still calm and professional.

I shifted carefully, trying to find a better angle through the floorboards. The service hatch in the laundry alcove remained open above me. If I climbed the ladder, I would emerge beside the stacked washing machine and tumble dryer. From there I could see the front door along the short passage.

I did not climb.

Instead, I moved towards the far corner of the underfloor void, where a narrow gap between the foundation stones admitted cold outside air. I crouched and peered through.

The angle was poor. I could see only part of the drive and a narrow section of the garden sloping towards the trees. The pond lay beyond them, about 12 metres west of the cottage.

I pressed my face closer to the gap, trying to widen my view.

The pond became visible between the trunks, just barely. It was a dark oval reflecting nothing. Its surface had become black and smooth, untouched by wind or ripples.

Something pale drifted upwards beneath it.

A face.

Its eyes were open.

I jerked away from the gap, my breath catching in my throat.

Do not look into the pond after sundown.

Rule two.

I had looked.

I backed towards the ladder, my pulse hammering in my ears. Above me, the boots moved closer to the broad front window overlooking the drive.

I climbed quickly, gripping the damp wooden rungs while my head torch threw wild strips of light across the foundation walls. I emerged through the hatch into the laundry alcove and stood there breathing hard.

The lights in the cottage were still flickering, dim and unstable. Keeping low, I moved along the passage into the living room and approached the front window from the side.

The blinds were closed, but not completely. A narrow gap between two slats allowed me to see outside without making myself obvious.

I leaned closer.

The police officer stood less than a metre from the glass.

His face was illuminated from below by the torch held at his chest. He was looking directly at the window. Directly at me.

His expression shifted. It was not a grimace and it was not anger. It was a smile, but the edges were wrong. The corners of his mouth drew farther back than they should have, stretching his face into a shape that did not fit.

His mouth opened.

Too wide. Far too wide.

Then he raised one hand and tapped the window with his knuckle.

Once.

It was the same measured, careful tap I had heard before, in exactly the same rhythm.

I stepped back from the blinds.

The marine set hissed beneath the floor.

Static came first, followed by Callum Price's voice in the same calm operational tone.

"Mr Mercer, I'm going to need you to let me in."

The voice came from inside the cottage, from the radio in the underfloor void.

The figure wearing PC Price's face was still standing outside the window.

I moved away quickly, crossed the living room and threw the deadbolt on the front door. The metal scraped loudly into place. I stood with my hands shaking, staring at the locked door.

The tapping resumed, passing from window to window, slow and deliberate. Mapping. Testing. Waiting.

I walked away without looking back. The thing wearing the officer's appearance and voice remained outside, tapping the glass, while the marine set beneath the floor repeated words taken from an earlier transmission.

My laptop stood on the table, its screen dark and its secure connection to the NHS trust long dead.

Thirty-eight batches of identity-management and controlled-medicine access logs had been cross-referenced. Roughly fifty hours of work remained. My flight from Newcastle to Belfast was in thirty-eight hours. Missing the deadline would destroy the four-year referral network I had built as a freelance cyber-security contractor.

None of it mattered now.

I closed the laptop and left it on the table.

I went into the small, clean bedroom with its untouched double bed. My duffel lay on the floor by the wardrobe. I opened the side pocket and removed the compact repair case I had brought in from the hire car earlier.

It was a zipped nylon case about the size of a hardback book, containing precision screwdrivers for laptops, needle-nose pliers, a small hand torch, wire strippers, electrical tape, a 10 mm spanner and a roll of silver gaffer tape. I had bought the tape from an ironmonger's near my Leeds flat six months earlier, after finding a loose bundle of cables in a client's server rack.

I took out the gaffer tape.

The cottage lights flickered, dimmed and recovered.

I went to the first window, beside the table and facing east towards the drive and my disabled Astra. The blinds were already lowered. I raised their edge and examined the seam between the frame and sill.

It looked tight. It probably had been tight when the cottage was built or refurbished.

But the rules had warned me about any opening wider than two fingers.

I tore off a strip of tape about 20 centimetres long and pressed it firmly along the bottom seam, smoothing it with my thumb so the adhesive gripped both painted wood and metal. I laid a second strip over the first, then sealed the sides with vertical lengths covering the joins between the window frame and wall. I taped the top seam last.

The tapping had stopped.

I froze and listened.

Nothing.

My mobile showed 22:14. Sixteen minutes remained before the circling period began.

I moved to the next window at the front of the cottage, on the opposite side from where the imitation officer had stood. Before sealing it, I drew the blinds aside and looked out.

I could see very little. The beam from my head torch reflected off the glass. Beyond it were only trees and darkness.

I sealed the window at the bottom, sides and top, pulling every strip tight.

The bathroom had a small frosted window above the lavatory. I stood on the closed lid and taped it shut. There were two windows in the bedroom, and I sealed both. I taped the kitchen window above the sink.

I checked the ventilation grilles as well. Fine metal mesh already covered them, but I ran tape around every frame and over any join that looked uncertain.

Then I returned to the living room and examined the front door.

It was solid wood, with no letter box and no pet flap. The gap beneath it was perhaps a centimetre wide. I tore off a long strip of tape and pressed it along the threshold, sealing the space between the door and floor, then added a second strip.

The weather seals at the sides and top appeared sound, but I covered them anyway.

There was a rear door beside the kitchen, narrow and secured with a deadlock. I locked it, sealed the threshold, then taped the frame on all four sides.

My mobile showed 22:26. Four minutes remained.

I hurried to the laundry alcove. The service hatch to the underfloor void was still open. I should have closed it earlier, but I had been too intent on the windows.

I crouched and looked into the darkness below. The marine set remained on its shelf, its green display showing Channel 16.

I swung the heavy wooden hatch shut. It settled into the frame with a solid thump. The panel was about five centimetres thick and fitted tightly. I sealed its edges with gaffer tape, then pushed the stacked washing machine and tumble dryer back over it.

At 22:29 I returned to the living room and sat in the chair facing the cold hearth, central and away from the exterior walls, exactly as the rules instructed. The sofa was too close to the front windows and the table stood near the east wall. The chair was the safest place available.

I switched off my head torch and placed it on the floor beside me. The cottage lights continued to flicker, but they remained on, dim yet bright enough for me to see.

I watched the clock on my mobile.

22:30.

The tapping stopped completely. I had already noticed its absence, but now the silence felt heavier, almost dense.

Then the circling began.

It did not sound like footsteps, boots on gravel or weight on the porch. It was a slow dragging noise against the outside of the cottage, as though something heavy were being hauled along the cladding, or something pressed to the wall were pulling itself around the building.

The sound began at the front. It passed the taped window to my left as a low, sliding scrape. It was not wood against wood. It sounded softer but denser, like wet canvas or thick rubber.

It continued along the east wall and past the window beside the table, slow and even.

I did not turn my head. I kept my eyes on the hearth and counted my breaths.

The sound reached the rear corner, paused for perhaps three seconds, then continued along the back wall. It passed the bathroom and bedroom windows before reaching the west side.

There the noise changed. It became wetter.

That wall faced the pond.

I kept breathing. In through my nose. Out through my mouth.

The dragging moved along the west wall towards the front corner, turned, then passed across the front again. It went by the window where the false officer had stood and across the door I had sealed with gaffer tape.

It completed the circuit and immediately began another.

Front to east. East to back. Back to west. West to front.

The rhythm never varied. Each circuit lasted about forty-five seconds. It neither accelerated nor slowed, pausing only at each corner.

I checked my mobile.

22:38.

Fifty-two minutes remained.

The radio hissed beneath the floor.

Static came first. Then a woman's voice.

"Daniel, it's Rebecca."

I went rigid.

Rebecca Shaw. My supervisor at the NHS foundation trust. The woman who had signed the contract and called six times in the previous seventy-two hours for progress reports.

Her voice came through the radio with perfect clarity, exactly as it sounded during our project calls. Brisk, efficient, with no wasted words.

"Daniel, I don't know what's happening, but the monitoring system shows your secure connection has been offline for three hours. I need you to call me immediately. The information-governance auditors are due on Monday, and if those access-control records aren't reconstructed, we're both in a very difficult position."

The dragging continued its circuit outside. It did not pause or react to her voice.

"I'm driving up there now," Rebecca said through the radio. "I have your location from the connection logs. I'll arrive in twenty minutes. When I get there, open the door so we can discuss this face to face. This is not optional."

I stared at the hearth and did not move.

Outside, the thing completed another circuit.

Front to east. East to back. Back to west. West to front.

"Daniel, I'm serious," Rebecca said. "Open the door when I knock. We'll sort this out, but I need you to cooperate."

The transmission ended.

I remained in the chair, counting circuits as the sound passed the front window, the east wall, the back, the west and the front again.

The set had first reproduced PC Price's earlier transmission, made before he was taken. Now it had intercepted Rebecca's live electronic message and copied her voice. It was not predicting anything.

It was learning voices carried through devices, borrowing them and using them as bait. It wanted people to open doors, step outside or break the rules because someone familiar or authoritative told them to.

I would not engage with it. I would not answer. I would not open anything.

My mobile showed 22:51.

Thirty-nine minutes remained.

The dragging continued, circuit after circuit. It did not stop or change.

23:03.

23:17.

23:24.

My neck ached from holding my head still. My shoulders had tightened into knots. I wanted to stand and stretch, but the rules said to remain seated in the centre, away from exterior walls. They did not say I could move during the circling period.

I stayed in the chair.

23:28.

Two minutes remained.

The dragging passed the front window again, moved along the east wall, rounded the back, crossed the wetter-sounding west side and returned to the front.

At 23:30 it stopped.

Complete silence.

I counted to sixty before moving.

Then I stood, grabbed my head torch and hurried to the laundry alcove. I dragged the stacked machines aside, tore through the tape around the hatch and opened it. I descended the ladder quickly, my boots striking the packed earth below.

The consumer unit was on the far wall. I gripped the main switch and pushed it down.

Everything went dark. The marine set's green screen vanished.

I counted to three and reset the switch.

The cottage lights surged to full brightness. They no longer flickered. The light was steady, strong and warm.

A loud crack sounded outside as the exterior floodlight came on. Perhaps there had been a second lamp behind the first, or perhaps whatever had interfered with it had released its hold when I reset the circuit. I did not know.

I climbed rapidly into the laundry alcove, ran to the front window and pulled the blinds aside.

The floodlight blazed over the porch, the drive, the gravel and the nearest row of trees.

Something was pressed against the outside of the front window, with only the glass between us.

It was not PC Price. Not any longer.

It was pale. It had skin, or something resembling skin, but it was too smooth and too wet. Its face was flattened against the glass, eyes and mouth open.

It was the face I had seen rising beneath the pond.

It smiled. The corners of its mouth drew back much too far.

Then it peeled itself away from the glass and ran.

Not towards the drive. Towards the pond.

I watched it sprint across the garden with impossible speed. Its arms and legs bent wrongly at the joints.

It reached the pond's edge, and the water rose.

There was no wave or ripple. The entire surface lifted into a smooth vertical wall, first three metres high, then nearer five, perfectly flat and still.

The creature stopped at the water's edge.

Behind the raised wall, just beneath its surface, a pale face pressed forwards. It was the same face, or perhaps another. I could not tell.

The rules had forbidden me from going outside before sunrise. But the lost insert had vanished in the hearth, and the restored floodlight had exposed the thing in retreat. For the first time it was fleeing rather than circling, and the water connection to the drowned caves lay open in front of me.

It was a narrow exception, inferred rather than promised. If I was wrong, I would die on the porch.

I picked up my head torch, fitted it over my forehead and switched it to its brightest white setting.

I unlocked the front door, pulled it open and stepped outside.

Cold air struck my face. The metallic smell had gone.

The floodlight covered the porch, and my head torch cast a hard white beam towards the wall of water and the face behind it.

I raised my fist and struck the door frame once.

Hard. Loud. Deliberate.

One clean, controlled knock in the exact rhythm it had used against the windows.

All night I had answered its single taps with one quieter tap and silence. This was the same exchange inverted: not submission, but a challenge thrown back at it.

The wall of water shuddered.

Ripples broke across it from top to bottom. The face behind the surface recoiled.

Then the wall collapsed.

The water fell vertically and struck the pond with a sound like thunder. Spray burst across the bank. For three seconds the surface churned and bubbled.

Then it became smooth again.

Completely still. Black as a mirror.

The garden was silent. The creature that had run towards the pond was gone.

I stood on the porch, breathing hard, my head torch aimed at the water.

Nothing moved.

I waited thirty seconds, then a minute, then two.

Still nothing.

I went back inside, locked the door and inspected every window, both doors, the sealed vents and the service hatch. The lights remained bright and steady.

I moved the machines again, opened the hatch and climbed into the underfloor void one final time.

The VHF set stood on its shelf with a dark screen. There was no green backlight and no static. I pressed its power button.

Nothing happened.

It was dead. Completely offline.

I climbed back into the cottage, closed and resealed the hatch, then pushed the stacked washing machine and tumble dryer over it.

I switched on every light: ceiling lights, wall lights and lamps. The exterior floodlight was already burning, and I left it that way.

I placed the chair in the centre of the living room and sat facing the front windows.

I did not open the laptop. I did not check my work or think about the deadline, the flight or the contract. I watched the windows and waited for sunrise.

My mobile showed 23:41. Seven hours and one minute remained until dawn.

I did not sleep.

Sunrise came at 06:42.

Through the front windows, I watched the sky change from black to deep blue and then to pale orange. I waited for full daylight, until the drive, the trees and the pond were clearly visible.

Only then did I unlock the door and step outside.

The floodlight was still on, though it looked faint in the morning sun. The damaged power cable still hung in torn lengths from the roofline, its wires exposed.

I descended the steps and crossed the gravel to the Astra. The bonnet was still latched.

I released it and looked inside. The battery leads remained disconnected. The red lead had been twisted around the air intake, while the black one was looped through the frame.

I tried to pull the black lead free. It did not move.

The powerless car could not respond to the key fob. I lowered the bonnet and checked the doors and boot manually. Everything looked as it had the night before.

Then I looked beyond the Astra, farther down the drive.

Another vehicle was parked roughly 30 metres downhill, hidden during the night by the slope and darkness.

It was a marked Northumbria Police 4x4 response vehicle with a light bar on its roof.

I walked down to it.

The driver's door was unlocked. I opened it and looked inside.

The vehicle was empty.

Its keys remained in the ignition. The dashboard radio was switched off. A laptop mount stood between the front seats, but the laptop itself was missing. On the passenger seat lay a clipboard holding blank police incident sheets.

The dashboard log displayed PC Price's name and collar number.

I closed the door and walked around the vehicle. There was no visible damage. The paintwork was unmarked and the tyres were intact.

Through the rear windows I saw the standard partition separating the front and back compartments. Nothing else looked unusual.

I continued downhill, studying the gravel.

About six metres beyond the police vehicle, I found the drag marks.

Two parallel grooves had been cut deeply and consistently into the gravel. They left the drive on its western side and led into the trees, towards Kielder Water.

I followed them through the undergrowth and between two tall conifers as the ground sloped down towards the reservoir.

The marks ended at the water's edge.

The shallows were clear and still. I could see stones and silt beneath the surface.

There was no body, uniform or equipment. Only the grooves ending in the reservoir.

I stood there for perhaps a minute, then walked back uphill.

My mobile still showed no signal. I could not repair the car, could not call anyone and could not remain at the cottage.

I returned inside and collected my duffel from the bedroom. I left the laptop, charging lead, external storage devices and hub where they were. If the thing could travel through transmissions or use any connected device to carry a familiar voice, I wanted no part of the equipment that held Rebecca's messages or the trust's access records.

I took only my wallet, keys and mobile. I kept the phone because I still needed a route out, but I resolved to discard it the moment it reconnected and began receiving anything.

I walked down the drive, past the disabled Astra and PC Price's abandoned response vehicle.

At Forest Track 17, the unclassified Forestry England route shown on the sat-nav, I turned towards Kielder village. It should take forty or fifty minutes on foot to reach a proper road.

The sun was bright and growing warm. The air smelt of pine, and birds called from the canopy.

I walked quickly without looking back.

After about twenty minutes the trees opened on my left. Through the trunks I glimpsed dark, smooth water connected through the drowned valley to Kielder Reservoir and the caves sealed beneath it.

I kept walking. I did not stop or look directly towards it.

It took forty-three minutes to reach Bakethin Road and another fifteen to reach the edge of Kielder village, where I had passed a petrol station, an outdoor-supplies shop and the village post office the previous day.

My mobile buzzed in my pocket.

I took it out.

Three bars of signal had returned. Messages, voicemail notifications and emails began loading at once.

One text from Rebecca Shaw had been sent at 23:04 the previous night.

"Call me immediately."

I walked to the petrol station and dropped the mobile into the rubbish bin beside the pumps.

Then I continued towards the village centre until I found the small branch library. It was a modest brick building with an OPEN sign in the window.

Inside, I asked the woman at the desk whether I could use a computer. She said I could and pointed towards a row of terminals against the wall.

I sat before one of them and stared at the screen.

I did not sign in to my email. I did not check the contract or open the NHS trust's systems. I did not play a voicemail or touch anything that might carry a familiar voice back to me.

I simply sat there until my hands stopped shaking.

Then I went outside and began looking for transport south.
