The Rules of Strathmuir

The subsidised regional flight touched down with a jolt that rattled my teeth. I gripped the armrests, knuckles white, as the small aircraft skidded along the icy runway before slowing to a crawl. Beyond the frosted window, snow covered the moor in every direction, broken only by the dark smudges of distant conifers and the low shapes of the hills.

Welcome to Strathmuir, in the north-west Scottish Highlands.

Population: approximately 420 permanent residents. My new home for the foreseeable future.

I pulled my holdall from the overhead locker and followed the handful of other passengers down the narrow aisle. The cold struck like a physical blow the moment I stepped on to the metal stairs.

My breath clouded in front of me as I hurried towards the tiny terminal building, the wind on that morning of 6 February 2023 cutting through my jacket as if it were not there. Inside was scarcely warmer. The terminal was a single room containing a few plastic chairs, a drinks machine and a bored-looking man behind the counter.

I stamped my feet to restore some feeling to my toes and looked around for whoever was meant to collect me. A man in a heavy Police Scotland parka stood by the exit with his arms folded. He appeared to be in his late fifties, with thinning grey hair and the weathered face of someone who had spent decades outdoors in hard country. When he saw me, he did not smile or wave. He merely gave a curt nod.

"PC Mercer?" he asked as I approached.

"Yes, sir."

I held out my hand.

"Daniel Mercer."

He shook it firmly.

"Inspector Malcolm Reid. The vehicle's outside."

That was all there was to the introduction. I followed him back into the cold, where an ageing marked 4x4 stood idling in the small car park, exhaust steaming in the frigid air. Reid put my holdall in the rear and climbed into the driver's seat without another word.

As we left the airfield, I tried to get a sense of the place through the misted windows. There was not much to see: snow, moorland, conifers and more snow. The single road looked only recently gritted, and Reid drove with the careful precision of a man who knew exactly where black ice tended to gather.

"First time this far north?" he asked at last, without taking his eyes from the road.

"Yes, sir. I spent most of my career in West Yorkshire."

"Yorkshire winters won't prepare you for this."

He said it matter-of-factly, not as though he meant to frighten me.

"It reached minus fourteen last week. Worse on the high ground."

I nodded, unsure what to say. The heater was working hard, but I could still feel cold seeping through the windows.

After roughly twenty minutes of silence, broken only by an occasional crackle from the Airwave radio, Reid reached into his coat and handed me a creased, weatherproof pocket card.

"Memorise these," he said. "Keep the card in your stab-vest notebook pouch. They'll keep you alive."

I expected severe-weather procedures or emergency contact details. Instead, five numbered rules had been typed on it.

One: If you hear laughter inside the station after dark, leave immediately.

Two: If you see someone with no face in the woodland, do not move until they leave.

Three: Do not acknowledge the whispers.

Four: Never open your door if someone knocks after midnight.

Five: Always feed the black cat if it crosses your path.

I stared at the card, waiting for Reid to smile or admit that it was some sort of initiation joke. When I looked up, his expression remained deadly serious, his eyes fixed on the road.

"Is this a wind-up for the new constable?" I asked, forcing a nervous laugh.

Reid glanced at me just long enough to make my smile disappear.

"PC Mercer, I don't have time for wind-ups. Those rules have kept me alive for twenty-six years in Strathmuir. They'll do the same for you, provided you follow them."

The way he said it sent a chill through me that had nothing to do with the weather. I read the rules again. They sounded like something from a cheap horror film.

"Sergeant Calder will explain more," Reid continued. "She's been here eight years. She knows what she's doing."

I slipped the card into my notebook pouch and decided to humour him. Every isolated community had its peculiarities and superstitions. This was probably Strathmuir's version.

We entered the village centre by way of a short High Street with a handful of buildings on either side. There was a cafe, a village shop with a medicines counter, a Post Office counter and sorting office, and several other businesses I could not immediately identify. Most had their lights on despite the early hour, their warm windows glowing against the grey morning.

Reid stopped outside a small, sturdy building bearing a Police Scotland sign and the words Strathmuir Police Station. It was a single-storey remote post with narrow windows and a metal roof burdened by snow.

"Home, sweet home," Reid said as he switched off the engine. "Get settled. Calder will take you out this afternoon."

The station was warmer than I expected. Fluorescent tubes hummed overhead. A small reception area opened into a room containing four desks, only one of which appeared to be in regular use. A coffee machine gurgled beside a small fridge, and a noticeboard covered in local information hung on the far wall.

Reid showed me an empty desk.

"This one's yours. The locker room is through there. Your flat is upstairs. Nothing grand, but it comes with the posting."

I set my holdall on the desk.

"Thank you, sir. When will I meet Sergeant Calder?"

"She'll be in at noon. Sort your kit until then."

Reid started towards his office, then stopped at the door.

"And Mercer."

"Sir?"

"Those rules aren't a joke."

He disappeared into his office, leaving me alone with my thoughts and the strange card in my vest.

I spent the next few hours unpacking and learning the station's layout. The flat upstairs was small but serviceable: one main room with a kitchenette, a bed and a sofa, plus a tiny bathroom. Its windows overlooked the High Street, where a few people, bundled against the cold, went about their business.

At exactly noon, the station door opened and a woman walked in. She was in her mid-forties, with prematurely grey hair cut in a practical bob and sharp blue eyes that seemed to register everything at once. Beneath her police jacket, she wore the same uniform as Reid, supplemented by sensible layers for the weather.

"You must be Mercer," she said, extending a gloved hand. "Sergeant Ruth Calder."

"Daniel," I replied as we shook hands. "Good to meet you."

She nodded and moved towards the coffee machine.

"Reid said you're from West Yorkshire. That's something. At least you know what snow looks like. The last officer they sent us was from Kent. He lasted three days before packing his bags."

Calder poured two mugs of coffee, handed one to me and took a long drink from her own.

"Reid give you the rules?"

I tapped the notebook pouch on my vest.

"Right here."

"Good. Ready to see the village?"

I picked up my coat.

"Lead the way."

Outside, the day had brightened slightly, although the sun remained behind a solid blanket of grey cloud. Calder led me to another marked 4x4 fitted with winter tyres.

"We'll take mine," she said. "It handles the snow better."

As we drove slowly along the High Street, Calder pointed out the important places: the village shop and its medicines counter, the cafe, the sorting office, and the NHS health centre staffed by one GP, Dr Aisha Rahman, and two district nurses, Morag Campbell and Priya Shah.

"About four hundred and twenty people live here permanently," she explained as we turned into a residential road lined with small houses. "Most work at the forestry depot or timber yard, or with the fishing boats on the loch when conditions allow. Others manage crofts, stalk deer or work in tourism. Everyone knows everyone, which makes our job easier in some ways and much harder in others."

I nodded, making mental notes.

"Seems quiet."

"Usually is. We deal with the ordinary things: domestic incidents, drunk and disorderly behaviour, the occasional theft. But that isn't what you need to worry about."

She turned on to a narrow road leading towards the edge of the settlement, where the houses became sparse and the conifer plantation pressed closer.

"The rules Reid gave you are what keep you alive here."

I studied her profile, trying to judge whether she was serious. Her expression revealed nothing.

"About those rules," I said carefully. "They're a little... unusual."

Calder kept her eyes on the road.

"Three officers ignored them during the years I've been here. None lasted a week."

A chill moved down my spine despite myself.

"What happened to them?"

"They were transferred out immediately."

Her tone made it clear that there was more to the story, but she did not intend to share it yet.

We drove in silence for a few minutes before Calder stopped where the woodland reached the verge. She switched off the engine and turned towards me.

"Look, Dan, I know how it sounds. I thought the same when I arrived. But Strathmuir isn't like other places. Things happen here that don't make sense. The rules help us navigate them. They reduce the risk. They aren't magic, and they won't protect you from everything."

I did not know what to say, so I nodded. Calder appeared satisfied and started the vehicle again.

As we approached the station, she slowed and pointed towards it.

"Rule one is the most important. If you hear laughter inside the station after dark, a child laughing, you leave. Don't investigate. Don't search for the source. Get out and contact me or Reid."

I waited for some sign that this was an elaborate prank. Her face remained grave, and the intensity in her eyes made me uncomfortable.

"Understood," I said.

"Good."

She pulled into the station car park.

"We'll discuss the others when they're relevant. For now, remember rule one."

My first week in Strathmuir passed without incident. I dealt with a noise complaint at the cafe, helped Mrs Jean Fraser after she locked herself out of her house, and attended a minor collision in the village shop car park.

It was normal rural policing. Reid and Calder were competent and professional. Apart from the rules, everything about the post seemed routine. We patrolled, updated incident logs and drank too much coffee.

By my seventh day, I had begun to relax. I decided the rules were local folklore, perhaps a way of keeping newcomers alert. Maybe they were even a psychological test of how officers reacted to peculiar situations. Reid and Calder's solemnity was simply commitment to the performance.

That evening, as I finished paperwork before going upstairs to the flat, I smiled at how needlessly worried I had been. Strathmuir might be remote and bitterly cold, but it was only another small community.

I put the weatherproof card in my desk drawer, convinced I would not need it. I had been a police officer for ten years. I knew the real rules of the job: remain alert, prepare properly and do not take unnecessary risks.

The folklore could stay in the drawer.

On my eighth night shift, I scraped ice from the windscreen of a response vehicle. It yielded reluctantly beneath the plastic edge, and the night air bit through my gloves, stiffening my fingers. I had still not adjusted to Strathmuir after dark.

The station stood silent behind me, fluorescent light shining from its windows. I had left my coffee inside and meant to collect it once I had cleared the glass.

I made two more strokes with the scraper.

A laugh broke the silence.

It was high-pitched and childlike, and it came from inside the station.

I stopped with the scraper raised. Perhaps I had imagined it.

Then it came again: a clear, delighted giggle that lifted the hairs on my arms beneath several layers of clothing.

Rule one flashed into my mind.

If you hear laughter inside the station after dark, leave immediately.

The laughter grew louder, seeming to rebound from wall to wall. My chest tightened as it passed through the closed doors and windows with unnatural clarity.

I dropped the scraper and backed away, fumbling for my radio with numb fingers.

"Sergeant Calder," I said, struggling to keep my voice steady. "I'm outside the station and I..."

The laughter cut through again, higher now and frantic.

"I can hear it," I finished, my breath clouding before my face.

Calder answered at once, urgency tightening her voice.

"Get into your vehicle now. Do not go back inside. Drive to my house, Dan. Now."

I did not need telling twice. I wrenched open the driver's door, got in and started the engine. As I left the car park, the laughter seemed to follow, hanging in the darkness even as the station receded behind me.

The drive to Calder's cottage took fifteen minutes along narrow, winding back roads. I kept checking the rear-view mirror, half expecting to see something following me. Nothing appeared, but the laughter repeated in my thoughts.

Calder's cottage stood near the edge of the settlement, a compact stone building with smoke curling from its chimney. I parked beside her 4x4 and waited with the engine running and the heater on full.

Five minutes later, she emerged carrying two steaming travel mugs. She came to my window and gestured for me to lower it.

"Are you all right?" she asked, passing one mug to me.

I wrapped both hands around its warmth.

"Yes. What the hell was that?"

"That," she said, leaning against the door, "is why we have rule one."

"A child's laugh in an empty police station?"

Calder drank before answering.

"I've heard it twice in eight years. Both times I did exactly what you did. I left and stayed away."

"What happens if you don't?"

Her face hardened.

"Three officers failed to follow that rule. They went back inside to investigate. We found them the next morning, sitting at their desks and staring at nothing. They wouldn't speak. They wouldn't move unless someone guided them. All three were admitted to psychiatric units within days and never returned to duty here."

I swallowed. The coffee suddenly tasted bitter.

"What caused it?"

"Do you truly want to know?" Calder asked, studying me.

"Yes."

She sighed, her breath visible in the cold.

"I don't know exactly what it is. None of us does. But it isn't a child, Dan. It has never been a child."

We remained there for the rest of my shift. Calder went inside but checked on me every hour, bringing fresh coffee and sitting in the passenger seat while I tried to process what had happened.

By dawn, when pale pink light spread over the snow, the incident seemed almost dreamlike. Only the lingering chill told me otherwise.

Two weeks passed without another incident. I dealt with ordinary calls, including a welfare check on Old Mr Galloway after heavy snowfall, livestock wandering on to the main road, and helping residents clear vehicles stranded by a drift. The laughter receded to the back of my mind, although I never again remained alone inside the station after dark.

Then I encountered rule two.

I was investigating property damage beside the native woodland. Ewan MacRae had reported that part of his deer fence had been torn down for the third time.

The damage was peculiar. Nothing had been cut. Two heavy strainers had been ripped from stony, frost-hardened soil as though something had dragged them out by force. I photographed the scene, made notes for the incident log and was about to return to the 4x4 when movement among the trees caught my eye.

About forty-five metres away, partly concealed between the trunks, stood a figure. It was tall, much too tall to be human, and its limbs hung at unnatural angles. Its skin appeared pale and almost translucent in the weak afternoon light.

My hand moved instinctively towards my Taser, then stopped as I remembered rule two.

If you see someone with no face in the woodland, do not move until they leave.

The figure stepped out from the trees, and my breath caught. Where its face should have been, smooth, featureless skin stretched across something roughly shaped like a human head.

My heart hammered as I held perfectly still. I scarcely dared blink.

The creature tilted its head as though studying me. It took another step and copied my posture: feet slightly apart, arms by its sides. Then it slowly raised one hand, matching the position of my right hand near my equipment belt.

We remained locked in that grotesque imitation while the minutes passed. Cold air burned my lungs, but I did not move, even when it took another step closer. Its movements were abrupt and wrong, like those of something learning how joints worked.

Nearly twenty minutes passed. My muscles began to cramp. The faceless figure continued mirroring me, sometimes tilting its head as if baffled by my stillness.

At last it appeared to lose interest. It lowered its arm, took three steps backwards and then turned with sudden, unnatural fluidity. A moment later, it disappeared among the trees.

I stayed where I was and counted slowly. One minute. Five. Ten.

Only then did I let myself breathe properly. Keeping my eyes on the woodland, I backed towards the response vehicle. I did not turn away until I reached it, and even then I fumbled the keys and dropped them before managing to unlock the door.

Inside, I sat with both shaking hands on the steering wheel and tried to understand what I had seen. The faceless figure had been real, as real as the ruined deer fence and the hard ground beneath my boots. As real as the laughter in the empty station.

I started the engine but did not immediately move. I watched the trees, expecting the figure to return. It did not, though I could not escape the sensation that it remained just beyond sight.

Reid and Calder had not been testing me. They had not been maintaining a village tradition or playing an elaborate joke.

They had been trying to keep me alive.

Later that month, I woke to knocking.

Three sharp blows struck the door of the station flat, precise and deliberate.

My mobile showed 2.00 am. The darkness beyond the window confirmed it. I sat up, instantly alert, wondering who could be outside at that hour.

The knock came again with the same rhythm and force.

I took my PAVA spray and baton from beside the bed and moved quietly towards the door, keeping to one side of it.

"Hello?" called a woman's voice from the landing.

It sounded wrong. The pitch was flawless and the tone musical, yet something about it tightened my skin.

"My car has broken down on the main road. I need to use a telephone, please."

Each word was pronounced with unnatural precision, as though the speaker were reading from a script she had rehearsed too often.

I remembered the pocket card.

Rule four: Never open your door if someone knocks after midnight.

"I can see your light is on," the voice continued in that eerie, lilting tone. "Please help me. I'm alone out here."

I stepped farther back, keeping my equipment ready.

"I'll telephone for assistance," I said. I did not approach the handle.

"Just open the door," the voice insisted, losing some of its melody. "I only need to use your telephone for a minute."

With my free hand, I rang Calder. She answered on the third tone, her voice thick with sleep.

"There's someone at my door," I said quietly. "A woman claiming her car has broken down. It's 2.00 am."

Calder became alert at once.

"Don't open it. I'm on my way. Keep her occupied if you have to, but stay inside."

I ended the call and raised my voice towards the landing.

"Help is coming. Someone will be here shortly."

The knocking stopped.

For several long seconds there was silence. Then came the sound of nails, long and hard, dragging slowly down the outside of the door.

"I only need to come inside," the voice said, abandoning any pretence of normal speech. The words stretched and warped like a recording played at the wrong speed. "Open the door now."

I backed away.

"Help is on the way."

The scratching intensified and moved around the frame. Wood splintered.

"Let me in," the voice hissed. It no longer sounded remotely human. "Let me in now."

For fifteen minutes I stood in the flat, listening to the scratching and its intermittent, hissing demands. Then Calder's 4x4 pulled up outside, the engine breaking the night silence.

The scratching stopped instantly.

Heavy footsteps climbed the stairs. Calder knocked.

"Dan, it's me."

I checked through the spyhole before moving anything. Calder stood outside in her police jacket, one hand close to her equipment belt as she searched the landing.

I opened the door.

"Are you all right?" she asked, stepping inside.

"Yes. Whatever it was, it left when it heard your vehicle."

Calder nodded, produced a torch and examined the frame.

"Look at this."

Deep gouges scored the wood. Four parallel cuts, each nearly a centimetre deep, ran around the frame from top to bottom, as though something had tried to claw its way inside.

"What could do that?" I asked, touching the splintered edge.

"We don't give it a name," Calder said, her face grim in the torchlight. "But it has tried before. Three years ago, a holidaymaker staying at the local guest house opened his door when it knocked."

She paused.

"We found pieces of him in three rooms."

I swallowed.

"Christ."

"You did the right thing. That's why we have the rules."

"What is it? Some kind of animal?"

Calder shook her head.

"Animals don't knock on doors and ask to use your telephone."

She examined the gouges once more.

"Reid will bring timber tomorrow and we'll repair this. For tonight, push the chest of drawers against the door."

After Calder left, I did exactly that. I shoved the heavy furniture into place and sat on the bed for the rest of the night with my baton beside me, listening for movement on the landing.

Sleep was impossible.

A month passed. New timber covered the claw marks, but I knew what remained beneath it. Every night, after locking the door, I ran my fingertips over the fresh paint and remembered.

One night I was alone at the station, catching up on paperwork. The clock showed 11.30 pm. The heating clicked and hummed, pushing warm air through the vents.

I got up to make coffee and walked past the empty desks towards the small staff room. As I passed Reid's office, I heard something.

A whisper, so faint that I almost missed it.

"Daniel."

I stopped.

The voice was unmistakable. It belonged to my father, Peter Mercer, who had died of a heart attack five years earlier.

"Daniel, I need to speak to you."

The whisper now came from behind me, near the front door. I turned just enough to scan the empty room, my hand moving towards my equipment.

Rule three.

Do not acknowledge the whispers.

I continued into the staff room, my heart pounding. I filled the coffee machine with trembling hands and concentrated on the simple task.

"Son, please. I don't have much time."

My father's voice again, closer now, directly beside my ear.

I gripped the worktop and stared at the machine as it began to gurgle.

"I know you can hear me, Daniel."

I took my mug and returned to my desk as though I had heard nothing. The whispers followed.

"Why are you ignoring me?"

Now it was my mother, Margaret Mercer's voice, gentle and wounded.

"Daniel, we miss you."

I sat, opened an incident file and began typing, keeping my attention on the screen.

"You always were stubborn."

My former wife, Laura Bennett, laughed exactly as I remembered.

"Do you remember that weekend in Manchester when we were caught in the rain?"

I kept typing, although my fingers trembled.

The whispers moved around the room. Sometimes they came close enough for cold breath to touch the back of my neck. Sometimes they spoke from the windows or beside the front door.

"Dan, mate."

It was my university flatmate, Nathan Cole.

"Remember when we climbed into that closed leisure-centre pool? We were absolutely hammered."

The voices cycled through people I knew, living and dead. Each copied the person's cadence perfectly. Each recalled things that no stranger should have known.

For an hour I sat at my desk, pretending to work while the whispers circled like hungry sharks.

Without looking away from the monitor, I picked up my mobile and called Calder.

"The whispers," I said when she answered. "They're here."

"Don't respond," she said immediately. "Don't turn towards them. Don't answer them. Don't react at all."

"I haven't. But they've been doing this for an hour. They're using the voices of people I know."

"They'll give up if you keep ignoring them. They feed on recognition. Acknowledgement gives them purchase."

She paused.

"I can come in if you need me."

A shadow crossed the wall, although nothing stood in a position to cast it.

"No," I said, keeping my eyes on the screen. "I can manage."

"Are you certain?"

"Yes. I'm learning the rules now."

After the call ended, the whispers continued for another twenty minutes. They grew more desperate and more personal. Then, as abruptly as they had begun, they stopped.

The station fell silent apart from the heating and the ticking wall clock.

I leaned back and breathed out slowly.

Four rules, I thought. I was beginning to understand how Reid and Calder had survived for so long. The rules were not superstitions. They were procedures developed through loss.

I looked into the darkness beyond the station windows and wondered what else waited there, and how many dangers had no rule at all.

By April, I had begun to learn some of Strathmuir's secrets.

I was on patrol when a black cat ran across the road in front of the 4x4. I braked at once, remembering rule five.

Always feed the black cat if it crosses your path.

After the faceless figure, the nocturnal visitor and the whispers, I no longer took chances with the card.

I stopped on the verge and left the engine running. The cat halted at the edge of the road, turned and sat facing me. It had one torn ear and a small white patch beneath its chin. Its yellow eyes looked far too knowing for those of an ordinary stray.

"All right, then," I muttered.

I reached for the packed roll on the passenger seat. Half remained, filled with smoked mackerel. The cat watched through the windscreen without moving.

I stepped out. The April air was cool but lacked winter's punishing bite. The cat stayed perfectly still as I approached, only the tip of its tail twitching against the tarmac.

"This is absurd," I said as I removed a portion of smoked mackerel and set it on the verge a few metres away. "But I suppose that's Strathmuir."

The cat approached cautiously, sniffed the fish and ate in small, delicate bites. I watched it consume part of my lunch and remembered every other rule I had encountered: laughter, a faceless mimic, the voices of the dead and the thing that knocked after midnight.

When the cat finished, it looked up and blinked slowly. Then it turned and slipped into the undergrowth.

I returned to the vehicle, shaking my head.

"I hope that was worth my lunch."

I resumed patrol, passing the village shop and cafe and checking the places where residents gathered. Strathmuir was quiet. The winter visitors had gone, and the summer holidaymakers had yet to arrive.

Two hours later, the control room sent me to a report of noise behind the sorting office.

"Probably youngsters," the controller, Joanne Kerr, said over the radio.

I acknowledged the call and drove there, parking beside the single-storey building. A loading area occupied the rear. I walked round with my torch in hand, although daylight still lingered.

The space behind the building was empty. There were no children and no obvious source for the reported noise. I was about to update the control room when something shifted in the shadows beside the bins.

A figure stood partly concealed there.

"Police," I called. "Come out where I can see you."

It stepped forward, and my hand moved instinctively towards my equipment belt.

It looked like a woman, or something constructed in a woman's shape. She wore what might once have been a dress, but the material appeared to shift as she moved. Her skin was so pale that it seemed translucent. Her eyes were entirely white and held a faint glow, without iris or pupil. One unnaturally broad mouth stretched across her face, filled with far too many teeth.

My throat went dry. I had faced armed offenders before, but nothing had prepared me for this.

The thing took another step. Her head tilted at an angle no human neck should allow. She sniffed the air as though testing my scent.

Her broad mouth turned down in disappointment.

Then she began to fade.

She did not retreat or run. Her body became transparent until there was nothing there at all.

I remained motionless for several seconds, my heart pounding. When I was certain she had gone, I pulled out my mobile and called Calder.

"I've just seen something behind the sorting office," I said. "A woman, but not human. White eyes, too many teeth. She sniffed at me and disappeared."

"Did you feed the cat today?" Calder asked immediately.

"Yes. About two hours ago. It crossed the road in front of me. Black, one torn ear, white patch beneath its chin."

I heard her exhale.

"Then you're safe from her. That's why she left."

"What was she?"

"We don't have a name for her. She appears every few months and takes people who haven't fed the guardian."

"The black cat is a guardian?"

"Something like that. Feeding it leaves a mark she can sense. It protects you from the white-eyed hunter, not from everything else in Strathmuir."

I leaned against the sorting-office wall as the adrenaline drained from me.

"What would have happened if I hadn't fed it?"

"You wouldn't be speaking to me now," Calder said. "Stay there. I'll meet you."

I waited beside the response vehicle, watching every patch of shadow until Calder arrived ten minutes later. She climbed out looking composed, as though we had arranged to meet for coffee rather than to discuss a predator that had vanished before my eyes.

"Are you all right?" she asked, studying me.

"Shaken, but yes."

She nodded.

"The first sight of her is always difficult. But you did well. You followed the rule."

"How many more of these things are there?"

"More than we've named. Some appear regularly. Others return only every few years. The rules keep us safe most of the time."

She surveyed the empty loading area.

"Sometimes something new appears, and we don't have a procedure for it. That's when it becomes difficult."

We searched behind the sorting office but found nothing unusual. There were no prints and no indication that the white-eyed woman had ever stood there. The incident log recorded a suspicious person who had left before officers could make contact. Then Calder and I returned to our separate patrols.

As April became May and then June, the days lengthened and the weather grew warmer. Summer brought walkers, anglers and families seeking a quiet Highland holiday. It also brought more encounters with the things living in and around Strathmuir.

On a mild evening in late June, I was called to the Rowan Hotel. A family of four from Surrey were leaving three days early and insisting that their room was haunted.

When I arrived, David Walsh was loading suitcases into a hire car while his wife, Helen, kept their children, Sophie and Ben, close beside her.

"Officer," David said when he saw me. "Thank God. We have to leave this place."

"What happened?" I asked, keeping my voice calm and professional.

Helen stepped forward.

"We saw my mother last night. She was standing behind a tree when we walked back from dinner."

"Your mother?"

"Her name was Patricia Webb. She died three years ago," Helen said, her voice breaking. "But it was her. She was waving at us from the woods. David saw her too."

I kept my expression neutral.

"I understand how distressing that must have been."

"You don't understand," David interrupted. "All four of us saw her. Even the children. And when we returned to our room, something scratched at the window all night. We're on the second floor."

I helped them finish loading the car, took a brief statement and watched them leave after promising that we would look into it.

I knew there was nothing useful to investigate. They were simply another family who had glimpsed Strathmuir as it truly was.

The following week, Calder and I escorted a lone holidaymaker, Oliver Shaw, to the coach stop on the main road after he reported something following him to the Rowan Hotel.

"It scratched at my window all night," he said, clutching his rucksack against his chest as we drove. "It kept whispering my name. How did it know my name?"

"Probably the wind," Calder said smoothly. "Old buildings produce all sorts of noises."

"It wasn't the wind," Oliver insisted. "It knew things about me. Private things."

We watched him board the coach, his face pale and exhausted. As it pulled away, Calder turned towards me.

"They never believe us when we tell them it's nothing," she said.

"But they wouldn't believe the truth either," Calder said. "Strathmuir exists in a place where the usual rules don't always apply."

She gestured towards the forest surrounding the settlement.

"The boundary is thin here. Things cross that shouldn't."

I thought of the faceless figure in the woods, the whispers that had used my father's voice, the white-eyed woman and the black cat with the torn ear and white patch beneath its chin that had saved me from her.

"Why here?" I asked. "Why Strathmuir?"

Calder shrugged. "Some places are simply like that. Thin places in the world. Most settlements built on them are abandoned eventually, unless the people learn to adapt."

"By following the rules."

"Exactly. The rules keep us alive." She looked at me. "You're beginning to understand, aren't you? This isn't village superstition."

I nodded slowly. "I'm beginning to."

As we drove back into Strathmuir, I watched the trees lining the road and wondered what else might be watching us. I thought of the family who had seen their dead grandmother, the holidaymaker who had heard whispers reciting his secrets, and all the other incidents that would never be described truthfully in a police log.

I was beginning to understand that Strathmuir occupied a place where ordinary rules did not always apply. Strange as it was, that understanding made me feel that I was finally starting to belong.

On 18 October 2023, the marked 4x4's engine spluttered twice and died with a forlorn whine. I turned the key again, but got nothing. Not even a click.

"Come on," I muttered, trying once more.

The dashboard lights flickered weakly, then went dark.

The first serious blizzard of the season had struck Strathmuir that evening, far earlier and harder than forecast. Snow swept past the station windows in horizontal sheets and had already banked against the north wall. The wind howled like a living thing and rattled the glass in its frames.

I took out my mobile and rang Inspector Reid. There was no answer. I tried Sergeant Calder next, but the call went straight to voicemail. The storm was evidently disrupting the mobile signal.

With a sigh, I climbed out of the useless vehicle and trudged through snow already above my knees to the station entrance. The metal door resisted as if frozen into its frame, then came free with a crack. I hauled it open and stepped inside.

At least the electricity was still on. The fluorescent tubes buzzed overhead, spreading their familiar pallid light across the empty desks. I checked my watch. It was 10.30 pm. The storm had intensified with astonishing speed after sunset, turning the world beyond the windows into a white blur.

I hung my jacket beside the door and brushed off the clinging snow. It seemed I would be spending the night at the station. That was inconvenient, but hardly a disaster. We kept a folding camp bed in the back room for precisely such occasions.

I made fresh coffee and settled at my desk to finish the day's incident logs. Outside, the wind grew steadily louder, making the old building creak and groan. Every few minutes I glanced at the windows and saw the drifts rising against the glass.

By 11.30 pm I had finished my paperwork and was ready to set up the bed. I stretched, then went to the little kitchen to rinse my mug. The lights flickered once, twice, then steadied.

"Brilliant," I said to the empty room. "Just what I need."

I fetched a torch from my desk drawer and kept it close. Then I took an emergency blanket from the supply cupboard and carried it to the back room. The wall clock passed midnight as I unfolded the camp bed.

I had just spread the blanket over it when I heard the sound.

A high, childlike giggle came from the main office.

My blood turned cold. Rule one: if you hear a child laughing in the station after dark, leave immediately.

I stood motionless, hoping I had imagined it. Then it came again, bright and innocent, a sound that had no place in an empty police station after midnight, with a blizzard raging outside.

My first instinct was to run for the door. Then I remembered the dead 4x4. Even if I reached it, I would be trapped in a metal shell without heat while the temperature outside fell towards -12 degrees Celsius. Attempting to walk through the storm would be suicide.

I could not obey the rule. I was trapped.

The laughter came again, louder now, as though it were moving along the corridor towards me. I backed away, my heart thudding. I needed another plan, quickly.

The supply cupboard had a solid door and a lock. It was not ideal, but it was the most defensible room in the station.

I grabbed my torch and mobile and moved as quietly as I could towards it. The laughter followed, rebounding from the walls. One moment it sounded directly behind me, the next as though it came from a distant room.

I slipped into the cupboard and pulled the door shut. My shaking fingers fumbled with the lock until it clicked. The space was barely 1.8 metres by 1.2, hemmed in by shelves of stationery, cleaning supplies and spare uniform. I wedged a folding metal chair beneath the handle, then sat in the corner furthest from the door.

My mobile showed one bar of signal. I rang Calder. She answered on the fourth attempt, her voice breaking through heavy static.

"Dan? Is that you?"

"It's here," I whispered. "The laughter. The 4x4 won't start and I can't get away."

"Where are you now?"

Her voice became sharp and controlled.

"Supply cupboard. I've locked myself in."

"Good. Stay there." Static swallowed several words. "We can't reach you. The road is closed and the storm's too dangerous."

"What do I do?"

I hated the crack in my voice.

"Stay inside the cupboard until daylight. Don't answer it, whatever it says or does. It feeds on fear and attention. The secured door should keep it out, but it can make you hear things anywhere in the building. Don't trust where the sound seems to come from."

The call dropped. I tried again, but could not reconnect.

Outside the cupboard, the laughter had stopped.

The sudden silence was worse. I sat perfectly still, listening. For several minutes there was nothing but the wind and the complaints of the old building.

Then I heard footsteps.

They were light and almost delicate, moving slowly along the corridor and pausing every few paces. They were too quick and slight to belong to an adult.

I held my breath as they approached. They stopped outside the cupboard.

The handle rattled gently. I watched it turn against the lock. The chair shuddered but held.

"Officer?" called a child's sweet, frightened voice. "Can you help me? I'm lost."

I clamped a hand over my mouth.

"I know you're in there," it said. The voice was still childlike, but something older and colder moved beneath it. "It isn't kind to hide from someone who needs help."

The handle jerked violently. The chair legs scraped across the floor as something pressed against the door. I forced my back against the wall and willed myself to disappear.

The pressure ceased. Silence returned and stretched until minutes felt like hours.

Then something giggled beside my ear.

I flinched away and swept the torch around the cramped space. There was nothing between the shelves. I was alone.

The laughter continued nevertheless, sometimes surrounding me, sometimes whispering straight into my ear. Calder had been right: whatever stood outside could manipulate perceived sound, though it remained unable to open the locked door.

The ordeal continued for hours. There were footsteps and laughter, then silences that drew my nerves taut. Sometimes there were whispers too faint to understand, which somehow felt worse. Twice the handle was tried again, with enough force to make the chair creak.

At 4.00 am, something began scratching the outside of the door. Long, slow strokes dragged across the wood. The noise continued until I wanted to scream simply to drown it out.

I watched the minutes crawl past on my mobile. At 5.00 am its battery fell below twenty per cent, so I switched it off. By 6.00 am my legs were numb and my back ached fiercely, but I did not dare move. Beyond the door, footsteps continued their irregular patrol, sometimes racing past and sometimes stopping as though to listen.

At 6.45 am, the light beneath the door changed. The hard fluorescence gave way to something softer and greyer.

Dawn.

The footsteps withdrew down the corridor. The laughter sounded once more, faint and distant, and then vanished.

I waited another forty-five minutes. At 7.30 am, with no sound but the ordinary creaking of the building, I moved the chair and unlocked the door.

My legs nearly folded beneath me when I stood. Pins and needles stabbed through both feet. I pressed my ear against the wood, listened, then opened the door a few centimetres.

The corridor was empty, washed in grey morning light. I eased the door wider. The station looked exactly as I had left it. Desks stood in place, papers remained neatly stacked and the coffee pot sat in the kitchen.

I stepped into the corridor on trembling legs, expecting the laughter to begin again. There was only the weakened moan of the wind as the storm abated.

I searched every room and corner. Nothing had been disturbed. Nothing was out of place. Without my aching body and the chair beneath the cupboard handle, I might have persuaded myself that I had imagined everything.

The snowfall had stopped, though drifts reached halfway up the windows. I switched my mobile on and called Calder. This time the connection was clear.

"Are you all right?" she asked at once.

"Yes. I think so. It's gone."

"Stay where you are. I'll collect you once the road through the High Street has been cleared."

Two hours later, she arrived with coffee and a grim expression. We said little as she drove me back to the station flat. There was nothing useful to say. We both knew what had happened.

The weeks and months passed. Autumn became winter, and winter softened into spring.

On 29 April 2024, Calder marked my first full year of service in Strathmuir. I sat at my desk, looking through the station window at the High Street, where local people went about their business beneath a clear blue sky. Everything appeared so normal.

I knew better. I knew about the faceless figure in the woodland and the thing that knocked after midnight. I knew about whispers that called people by name, and the white-eyed woman that hunted those who had passed the black cat without feeding it. I understood that the cat's protection applied to that hunter, not to every danger Strathmuir held.

I also knew the laughter that filled empty rooms after dark.

At last, I understood why Calder had remained for eight years despite all she had witnessed. Someone had to stay. Someone had to know the rules and help others follow them. Someone had to protect Strathmuir's approximately 420 permanent residents from the things waiting beyond the edge of ordinary reality.

I reached into the notebook pouch of my stab vest and took out the creased, weatherproof pocket card Reid had given me on my first day. Five typed rules. Simple sentences carrying the weight of lives. I ran my thumb over the worn surface and remembered how close I had come to dismissing them as folklore or an elaborate joke.

"Coffee?"

Calder stood in the doorway with two steaming mugs.

"Thanks." I took one and let its warmth seep into my hands.

"One year down," she said, leaning against the frame. "Thinking of requesting a transfer yet?"

I looked at her, then at the card. I thought of the guests at the Rowan Hotel who had seen their dead grandmother waving from the trees. I thought of the holidaymaker we had escorted to the coach stop after something spent a night whispering his secrets through the guest-house window. I remembered the hours in the cupboard while something that laughed like a child, but was not a child, tried to reach me.

I thought of all the truthful accounts we could never put into incident logs, and all the things Strathmuir's people would never know we did to keep them safe.

"No," I said, returning the card to my vest. "I'm staying."

A small smile crossed Calder's face. "Good. We need you."

She left me with my coffee and my thoughts.

Outside, the sun shone upon ordinary people living ordinary lives, unaware of what moved in the shadows when they were not looking, or what rules helped keep them safe.

That was the job. It was my job now: to know the rules, to uphold them and to stand between Strathmuir and whatever waited in the darkness beyond.

Later that year, I moved out of the station flat and into a small police cottage a short distance away. It gave me somewhere that felt like home, although it also meant that calls before dawn now began with a cold drive to the station.

At 7.00 am on 12 January 2025, my mobile rang just as I was pouring my first coffee. Inspector Reid's voice was clipped and tense.

"I need you at the village shop. It looks like vandalism overnight."

I put on my jacket and left the cottage. The morning air bit at every patch of exposed skin. It was about -8 degrees Celsius, cold enough to sting my nostrils when I breathed, but not unusual for Strathmuir in January.

The village shop stood near the centre, its stone walls and painted timber frontage weathered by decades of Highland storms. When I arrived, Reid was outside with the owner, Gordon Sutherland. Both were staring above the entrance.

"Morning," I said as I joined them. "What have we got?"

Reid pointed above the door. "Have a look."

A symbol had been cut into the wooden frame. Interconnected lines formed something like a twisted tree, or a hand with far too many fingers. The cuts were precise and deep, made by a blade finer than an ordinary penknife.

"When did you find it?" I asked Gordon.

"Opened about half an hour ago. It wasn't there when I locked up at 8.00 pm."

I photographed the mark with my work mobile. Nothing about it was overtly threatening, yet it made my skin crawl. If I studied the lines for more than a few seconds, dizziness began to gather behind my eyes.

"Did anyone see anything? Have you got CCTV?"

Gordon shook his head. "The camera failed during last month's storm. I haven't replaced it yet."

Reid put a hand on my shoulder. "This isn't the only one. We've had reports from the Post Office counter and the health centre."

I spent the next hour examining both. At the Post Office sorting office, the symbol had been painted on the front window in a dark red substance that I hoped was not blood. At the NHS health centre, a smaller, more intricate version had been scratched into the metal door plate.

Dr Aisha Rahman, Strathmuir's GP, stood in the doorway with her arms folded.

"This isn't the first time," she said quietly. "They appeared about four years ago as well."

"What did you do then?"

She glanced at the mark. "We removed them and pretended they hadn't been there."

By mid-morning, I had documented seven locations bearing versions of the same design. I was photographing one carved into a deer-fence post when Calder pulled up in a marked 4x4. She climbed out, her breath clouding in the air.

"You've seen them, then?" she said.

It was not really a question.

"What are they? Gang markings? Something connected to a cult?"

Calder examined the carving. "They appear every few years. The same basic pattern, always overnight."

Her gloved finger traced the air above the lines without touching them.

"The last time was four years ago. The time before that, six years earlier."

"What do they mean?"

"Nothing good." She looked at the heavy grey sky. "They tend to arrive before something happens."

"What sort of thing?"

"Four years ago, three walkers disappeared in a week. They went into the forest and never returned. Six years before that, an unnatural freeze hit the settlement. Pipes burst everywhere. Old Mr Galloway was found frozen in his bed."

I studied the symbol again. "So it's a warning?"

"More like an announcement." Calder took a small tin of matching paint from the vehicle. "We need to remove every one we find."

"Shouldn't we preserve them as evidence?"

"You've taken photographs. That's sufficient. They must be gone before dark."

We spent the rest of the day locating and removing the marks. Calder already had a method: paint for walls, sandpaper for timber and a metal file for the few cut into metal. By late afternoon, we had found and erased fifteen.

"Is that all of them?" I asked as we scrubbed the last visible mark from the wall of the cafe.

"Probably not," Calder said, dropping the used cloth into a rubbish sack. "But we've removed the public ones. That's what matters most."

"What happens now?"

She checked her watch. "You patrol. Watch for anything unusual."

"More unusual than symbols appearing overnight?"

She did not smile. "Much more unusual. Keep your Airwave radio on. Don't engage with anything that doesn't appear human."

"Rule three?"

"Use rule three if you hear the whispers. But if you see frost-shapes tonight, that's different. The older residents know the winter protocol: give them no attention, light or sound. Stay in the vehicle, keep moving slowly and don't look directly at them. The five rules reduce certain risks, Dan. They aren't a complete catalogue of everything here."

"What about you?"

"I'm checking our vulnerable residents. They need to be indoors before dark."

I began patrolling at 6.00 pm, just as night settled over Strathmuir. The roads were already deserted. People generally stayed home after dark in winter. Even without the entities, the cold and treacherous roads were reason enough.

My first circuit was uneventful. I drove slowly, watching houses and public buildings for renewed symbols or anything else out of place.

The dashboard showed -10 degrees Celsius. Harsh, but credible for a Highland cold snap. By 8.00 pm, I had completed two circuits and was beginning a third when the display dropped to -15.

Ten minutes later, it read -20.

I pulled over and contacted Calder by radio.

"Temperature is falling rapidly. Minus twenty and still dropping."

"Where are you?" Her voice tightened.

"Near the primary school."

"Stay in the 4x4. Keep moving, but slowly. If you see shapes or movement that shouldn't be there, don't look straight at it. No torch, no siren unless someone's life is in immediate danger, and whatever happens, don't leave the vehicle."

By 9.00 pm, the temperature had plunged to about -25 degrees Celsius, an unmistakable anomaly. The heater laboured, yet cold seeped through the windows. Frost repeatedly clouded the windscreen despite the demister.

That was when I saw the first shape moving between the houses opposite the school.

I initially mistook it for a person, but it moved too fluidly and too quickly. As it passed a lit window, frost blossomed across the glass in branching patterns like living veins.

I followed the winter protocol, facing forward and continuing at the same slow speed. I did not acknowledge what I had seen.

More shapes appeared. Dark, flowing forms glided from house to house, pausing at windows and doors. At the Mackenzie home, one pressed itself against the front door. Intricate frost spread across the wood. For a moment, I thought it might pass through. Then the porch light went out, the house fell silent and the shape moved on.

They were testing the homes, searching for a response.

I used the radio and telephone to warn residents whenever possible. Mrs Jean Fraser answered her landline on the third ring.

"Mrs Fraser, it's PC Mercer. Keep your doors locked, switch off every light and stay quiet. Don't respond to anything outside."

"I know, son," she replied calmly. "This isn't my first Strathmuir winter."

I called other houses in turn, repeating the warning. Lights went out one by one. The shapes appeared to avoid the 4x4, drifting away when I approached, but I saw them returning once I had passed.

Near midnight, several gathered outside the Bell family home. Frost thickened across the windows.

A light came on upstairs, and through the glass I heard a child's voice.

"Dad, there's someone outside."

The shapes pressed closer. The frost spread faster.

An immediate threat justified the risk. I angled the 4x4 across the drive to put its bonnet and headlights between the house and the nearest shapes, then gave one short burst of the siren. They scattered into the darkness between neighbouring buildings.

Remaining behind the open driver's door for cover, I approached only far enough to hammer on the Bell family's front door.

Mr Bell opened it, his face pale.

"What's happening?"

"Get everyone away from the windows. Lights off and no talking. Don't answer anything you hear outside."

He nodded, fear widening his eyes. "The frost..."

"It's drawn to attention, light and sound. Do exactly as I've said."

I returned immediately to the vehicle and resumed patrol.

One guest house had frost covering every window. Dark forms clustered around it, and I could hear frightened voices inside. The occupants were probably visitors who had never been taught the protocol. I found the number in the control-room incident notes and rang from the 4x4 rather than approaching on foot.

As I waited for an answer, I briefly raised my torch to confirm the house number. Its beam brushed one of the shapes.

The thing turned towards me. It had no face or features, only a deeper patch of darkness where a head ought to have been.

I switched off the torch at once, lowered my eyes and drove on. The mistake had taught me why Calder had warned against light as well as attention.

Throughout the night, I travelled slowly around Strathmuir. The frost-shapes tested doors and windows but did not enter homes whose occupants remained silent and still. Wherever lights stayed on or voices carried, the ice grew thicker and more elaborate, spreading from the glass on to entire walls.

At about 4.00 am, the shapes began withdrawing towards the forest. Their numbers thinned, and by 5.00 am they were gone. The temperature rose gradually from the impossible low of -25 to -15, then continued towards ordinary winter levels.

Dawn came at about 8.00 am, pale light washing over the settlement. Frost remained on doors and windows throughout Strathmuir, but already it was softening in the relative warmth.

I returned to the station exhausted. As I approached, fresh cuts on the entrance caught my eye.

Three new symbols had been carved into the door. They were larger and more elaborate than the marks we had removed, but unmistakably derived from the same twisted pattern. They had not been there when I left.

Whatever had made them had done so while I drove around the settlement watching the frost-shapes test people's homes. Perhaps the shapes themselves had carved them. At the time, I had no way to know.

I photographed each mark and rang Calder. We had removed them once and would remove them again, but I could not shake the certainty that this was only the beginning of whatever the symbols had announced.

Months passed without an explanation.

At 4.38 am on 17 August 2025, my mobile erupted beside the bed in the police cottage. I fumbled for it in the dark and saw Calder's name.

"Mercer," I answered, my voice thick with sleep.

"We've got a situation," she said, fully alert. "A family of holidaymakers went walking yesterday afternoon and didn't return to their rented cabin. The Walsh family: mother, father and two children, aged eleven and fourteen."

I sat up and reached for the bedside lamp.

"They went into the forest after all the warnings?"

"The father, Adrian Walsh, is a nature photographer. Apparently he thought the local stories would add interest to his photographs. They were explicitly told not to leave the marked tracks. The cabin owner, Moira Lennox, even made them sign an acknowledgement."

The disgust in her voice matched my own.

"Where are you?" I asked, pulling on my trousers.

"At the station. Reid is calling the others. We need people who know the land and understand the dangers."

I grabbed my jacket. "I'll be there in ten minutes."

The drive took seven. The streets were empty, and Strathmuir slept beneath a black sky broken by patches of stars.

At the station, Calder and Reid waited with five local people: Gordon Sutherland, Dr Aisha Rahman and three forestry workers, Callum Grant, Ross Muir and Iain Boyd. That made a fixed search party of eight: me, Calder, Reid, Gordon, Aisha, Callum, Ross and Iain.

All wore outdoor clothing and grave expressions. Callum, Ross and Iain carried powerful torches, billhooks and compact rescue axes.

"Mercer." Reid nodded towards the desk. "We're all here."

He had spread an Ordnance Survey map across it. "The Walshes told Moira they meant to follow this track and camp here."

His finger settled well beyond the safe walking routes, deep within a part of the forest every local knew to avoid.

Gordon shook his head. "That's bad ground. Very bad."

"Which is why they were warned more than once," Reid said.

"What's the plan?" I asked.

Calder indicated a point at the forest boundary. "We begin here and follow their probable route. We remain together without exception. Everyone here knows the rules. If you see anything, say so. If you hear something that isn't one of us, ignore it. No one goes off alone."

Each person nodded. These were not unprepared volunteers. They knew Strathmuir's secrets and understood what lived beneath those trees.

"Let's move," Reid said. "We have a few hours before sunrise. I'd prefer to be out by then, if we can."

We took two marked 4x4s to the start of the forestry track. The temperature was about 8 degrees Celsius, cool for August but comfortable in our layers. Each of us carried water, first-aid supplies, spare batteries and emergency equipment.

At the edge of the woodland, we formed a tight group. Reid gave his final instructions in the torchlight.

"Radio check every fifteen minutes. We move as one unit. If we find any sign of the family, we inform the control room immediately."

The forest swallowed us beyond the first rank of trees. Our torch beams cut through darkness that seemed unnaturally dense, catching on trunks, bracken and tangled undergrowth. The forestry track remained clear for the first kilometre and a half, marked by repeated signs warning walkers not to proceed beyond designated routes.

The Walshes had ignored them.

"Tracks here," Callum said.

He pointed to broken branches and four sets of prints in damp earth where the family had left the main route.

We followed them for another hour. The trees thickened and crowded together. The sounds of the woodland changed. Bird calls became scarce. In their place came long silences broken by rustling that seemed to originate everywhere at once.

"They definitely came this way," Calder said, crouching beside the trail. "Four sets. Two adults and two children."

The sky had begun to pale, but beneath the canopy it remained dark. We continued, following an increasingly erratic route. The Walshes had begun by moving with purpose, then started to zigzag as if they had lost all sense of direction.

"Look," I said.

My torch illuminated a symbol carved into a tree. It resembled those we had found throughout Strathmuir in January, though the cuts looked fresh.

"They didn't make that," Gordon said quietly. "It was waiting for them."

We found three more marked trees. The family's tracks passed each symbol directly, as if the carvings had drawn them deeper.

After another eight hundred metres, a patch of bright blue appeared between the trunks.

"There," I said. "That could be their tent."

We approached cautiously. In a small clearing stood a blue four-person tent, a portable stove and several scattered rucksacks.

The tent had been torn open from within. Long rents in the fabric gaped like wounds. Sleeping bags had been flung across the ground. There was no blood, but every part of the scene suggested violence.

"Christ," Ross whispered.

I circled the camp, sweeping my torch over the soil. The tracks there were almost human, but not quite. Some were footprints with toes elongated like fingers. Others were unmistakably handprints, their impossibly long digits pressed deep into the damp ground.

"Sergeant," I called softly. "Look at these."

Calder crouched beside me and examined the prints.

"They're fresh," she said. "Less than twelve hours old."

"What leaves marks like that?"

She shook her head. "Nothing you want to meet."

She rose and pointed. The strange prints formed a trail leading deeper into the native woodland, away from every established route. Among them were the Walsh family's ordinary tracks. The depth and spacing showed that both adults and children had been running.

Reid gathered us close.

"We follow, but keep tight. No one moves more than three metres from the group."

We advanced in formation, our torch beams crossing over the ground and surrounding trees. With each step, the forest became quieter. Soon there were no birds or insects. Even the wind died, leaving us inside a bubble of silence broken only by our breathing and footfalls.

We followed the tracks for nearly another kilometre before the trees opened abruptly. Ahead lay a perfectly circular clearing, perhaps fifteen metres across. Its surrounding trees stood at unnaturally regular intervals, as though planted to mark its circumference.

"I've worked these woods for thirty years," Gordon whispered. "I've never seen this place."

At the centre, the Walsh family's belongings had been arranged in a spiral: clothes, boots, watches, mobiles, wallets and the children's soft toys, every item placed with careful precision.

"Don't touch anything," Reid warned as we approached.

At the spiral's centre stood a small framed photograph of the family beside a Welsh reservoir. Adrian Walsh smiled beneath a beard. His wife, Helen, had long brown hair. Beside them stood their fourteen-year-old son, Owen, and eleven-year-old daughter, Megan. The frame's glass had been shattered, but the photograph beneath was untouched.

There were no bodies.

"Where are they?" Aisha asked, scanning the clearing.

Then I heard it.

The same high giggle I had heard in the station. A child's laughter came from everywhere and nowhere.

"Nobody move," I said quietly. "Don't answer it."

The laughter circled us. Whispers joined it, too faint to distinguish but laden with a terrible familiarity. I kept my gaze fixed on the spiral and refused to turn towards the sounds.

"We should split up," Callum said suddenly, his voice flat. "Cover more ground."

I looked at him. His eyes were fixed upon the trees, and he stepped away.

"No," Reid said firmly. "We remain together."

"I can see something over there," Gordon murmured, drifting in another direction. "I'm only going to check."

Something was badly wrong. Ross and Iain also began moving towards separate points around the clearing, their expressions vacant. They ignored Reid's orders to stop.

Calder seized my arm, her fingers biting through my sleeve.

"We have to leave now," she hissed.

"But the family..."

"They're gone. We will be too if we stay."

The whispers swelled. The child's laughter deepened into an adult register.

Callum, Ross and Iain had reached the edge of the clearing, each walking towards a different gap between the trees. Gordon followed them.

"Callum! Ross! Iain! Come back!" Reid shouted.

None reacted.

Aisha began walking towards the centre of the spiral. I caught her jacket, but she tore herself free with startling strength.

"Dan, now!" Calder hauled me backwards. "Inspector, we have to go."

Reid hesitated for one second, then gave a sharp nod towards the route by which we had entered.

"Run."

The three of us sprinted from the clearing, leaving Callum, Ross, Iain, Gordon and Aisha behind. The whispers pursued us, angry and insistent. The laughter warped into a sound like screaming.

I ran between Calder and Reid, trying to retrace our route. The forest had changed. The trees seemed closer, the undergrowth denser, and branches reached across our path like hands.

My jacket caught on something. I wrenched it free without looking back.

Movement flickered among the trunks. Pale forms, too tall and thin to be human, kept pace with us at the edge of sight. I glimpsed long limbs, stretched faces and fingers trailing across the ground. They never stepped fully into view, but they revealed enough to make their presence certain.

These were not the motionless faceless mimic I had met before. Whatever connection might exist between them, I could not know it then.

"Don't look at them," Calder gasped beside me. "Keep running."

My lungs burned. Branches lashed my face. I stumbled over roots and recovered without slowing. The sounds behind us drew closer.

Reid ran several paces ahead, his torch beam leaping wildly over the ground. We forced our way through a dense wall of branches and burst on to the marked forestry track.

The pale figures stopped where the deeper woodland met the route. I could not see their eyes, but I felt them watching.

We did not slow until we reached the vehicles. I bent forwards with my hands on my knees, fighting for breath. Calder leant against one of the 4x4s, her face colourless and wet with sweat. Reid stood staring back at the forest.

"The others," I managed.

"They're gone," Reid said flatly.

"We can't just leave them," I argued, though there was no conviction left in my voice.

I knew what I had seen. Callum Grant, Ross Muir, Iain Boyd, Gordon Sutherland and Dr Aisha Rahman had been lost the moment they chose to follow those voices into the trees.

Calder looked towards the native woodland. "Whatever is in there wanted them to separate from us."

"And it got what it wanted," Inspector Reid said.

The sky had lightened to the grey of early dawn. In the growing light, the woodland looked almost normal. Just trunks, bracken and wet undergrowth. Nothing sinister.

But I knew better by then.

"What about the Walsh family?" I asked.

Reid shook his head. "We'll record all four as missing and update the incident logs, but they're not coming back."

I looked from him to Calder. "This has happened before."

"Every few years," Calder confirmed. "Someone ignores the warnings or goes too deep. Sometimes we find pieces. Usually we find nothing."

We stood in silence as the weight of what had happened settled over us. Five members of our eight-person search party were gone. A family of four had vanished, and whatever had taken them was still out there, watching from among the trees.

"Let's go," Reid said at last. "We need to tell the others what happened."

We returned to the marked 4x4 and drove away. I looked back once at the edge of the woodland.

For a second, I thought I saw a small figure standing between the trees. It was no taller than a child, a dark silhouette with one hand raised as though waving goodbye.

Then it stepped backwards and disappeared, leaving only shadows and silent trees.

Four months later, on 18 December 2025, I first realised something had changed when I saw the white-eyed woman watching me from across High Street.

She stood perfectly still in the gap between the ironmonger's and the sorting office. Her single, unnaturally broad mouth stretched into the hungry smile I remembered.

That morning, the black cat with the torn ear and the small white patch beneath its chin had crossed my path outside the police cottage. I had crouched beside it and fed it a portion of smoked mackerel from my packed roll. It had eaten every scrap while staring up at me with steady yellow eyes.

The cat's protection had always kept the white-eyed hunter away from me before. Now she was back.

I continued along High Street as if I had not seen her. My hand stayed close to my baton and PAVA spray, although I knew neither would be much use. When I looked back, she was gone, but the cold sensation between my shoulder blades told me she had not gone far.

The whispers began the next day.

I was completing incident logs at my desk in Strathmuir police station when my name came from the supply cupboard.

"Daniel," a voice said in my father's exact tone. "Come here, son."

I kept typing. Rule three was simple: never acknowledge the whispers.

They did not stop when I ignored them.

They grew louder and followed me from room to room. By the afternoon they had become a constant background noise. My mother, my father, university friends and my former wife all called my name, told me secrets and asked questions only I could answer.

When Sergeant Calder arrived for her shift, I took her aside.

"It isn't working," I told her. "I'm following the rule, but the voices aren't stopping."

She studied me with the same steady blue eyes that had watched over me since my arrival in Strathmuir.

Her Airwave radio sounded. Reid's voice came through, clipped and urgent.

"Calder, bring Mercer to the village hall. Now."

We took her marked 4x4. Outside, the sky hung low and grey despite it being only 3.00 pm. As we drove through the village, I saw more white-eyed women standing at corners and in gaps between buildings, watching our vehicle pass. Each had the same pale face and one impossibly broad mouth.

They did not bother to hide.

"You see them as well?" I asked.

Calder nodded. "They're getting bolder. It's starting."

"What's starting?"

She did not answer. She drove faster through Strathmuir's empty streets.

The village hall was a two-storey timber building beside the green. Inspector Reid was waiting inside with seven residents I recognised: Mrs Jean Fraser, who had greeted me with a shotgun during the January frost incursion; Gordon Sutherland's older brother, Hamish; Dr Rahman's district nurse, Moira Beaton; Ewan MacRae; and three other elders I knew by sight - Elsie Munro, Alasdair Kerr and Margaret Singh.

Gordon and Dr Rahman should have been there too. Their empty places made the room feel colder.

"Good," Reid said. His weathered face looked more deeply lined than usual. "You're here. Close the door."

I shut it behind us and noticed fresh symbols carved into the timber frame. They resembled the twisted tree pattern that had appeared throughout the village on 12 January 2025, but these were cleaner and more deliberate. The lines had been cut at a different angle, with the branches turned inwards rather than out.

"Dan," Reid said, "you've been with us for nearly three years. You've learnt the five rules. You've seen what happens when people break them."

"Yes, sir."

"But the rules aren't working as they used to, are they?"

I shook my head. "The white-eyed woman has come back even though I fed the cat. The whispers don't stop when I ignore them."

"The rules reduce the danger," Calder said. "They were never spells. The cat marks you as protected from the white-eyed hunter, but only while the boundary is sound. It can't protect you from everything else."

Ewan MacRae, the oldest person in the room, nodded slowly. "It's time again."

Reid turned towards the gathering.

"Every thirty years, the boundary between Strathmuir and the other side weakens sharply. The rules that normally keep people alive are not enough during that period."

"The other side?" I asked.

"You've seen enough to know there is something beyond our world," Calder said. "A place where these things come from."

Moira Beaton continued where Dr Rahman might once have done. "Most of the time, the boundary is strong enough that only a few entities slip through. Every thirty years it thins until it is almost gone. The last renewal was in 1995. Before that, 1965."

Mrs Fraser's grey hair was pulled into a tight bun. "My husband served at this station in 1965. We lost seventeen people before the elders understood how to renew the boundary."

"And in 1995?" I asked.

"We were prepared," Reid said. "We lost three."

The room fell silent.

I thought of the Walsh family and the five people we had lost in the woodland on 17 August. I wondered how many more would disappear if we failed to act.

"What do we do?" I asked.

Hamish Sutherland opened a wooden box on the table and took out two flat stones, each about the size of my palm. Both bore the twisted tree symbol, carved with its branches curved protectively inwards. Leather cords threaded through holes at the top turned them into crude amulets.

He handed one to me and one to Calder.

"These are boundary keys," he said. "Local schist, taken from the bed of the burn that runs beneath Strathmuir. The symbol must be carved in the proper orientation and for the proper purpose."

I looked towards the fresh marks around the door. "But the symbols that appeared in January..."

"Warnings," Ewan said. "The same basic shape, but wrongly turned. Those marks showed where the other side was pressing through. A symbol can invite or repel. Material, orientation and intent determine which."

The stone felt warm in my palm, almost alive. When I looked away, the carving seemed to shift at the edge of my vision.

"You and Sergeant Calder will place larger stones at fixed points around the settlement's boundary," Reid said. "These amulets will connect you to them and let you close the circle safely."

"The winter solstice is on 21 December," Mrs Fraser added. "Three days from now. At midnight, the boundary will be at its weakest. If the circle isn't complete by then, it will collapse."

I slipped the leather cord over my head and let the stone rest against my chest.

"And if it collapses?"

No one answered at first.

At last Moira said, "Strathmuir stops existing as we know it."

We began before dawn on 19 December.

Calder collected me from the police cottage in the marked 4x4. The rear compartment carried twenty heavy dressed slabs of local schist, each roughly the size of a paving block and carved with the correctly orientated tree symbol.

"The elders prepared these," she explained as we drove towards the first site, north of the settlement where the main road passed into the conifer plantation. "They started after the warning symbols appeared in January."

"So they knew this was coming."

"They suspected. The August disappearances confirmed it."

We stopped on the verge. Beyond us, the plantation looked darker than it should have. The trees seemed to stand closer together, their branches interlocking above the forestry track.

Calder checked a hand-drawn map and pointed to the precise edge of the trees.

"Here. About thirty centimetres down."

I took the spade from the vehicle and cut into stony, frost-hardened soil. When the hole was deep enough, Calder lowered the first schist slab into it with the symbol facing upwards.

"Now we anchor it," she said, taking hold of her amulet.

I touched mine. A vibration passed through the stone at my chest and down through my boots into the buried slab.

"Did you feel that?" I asked.

She nodded. "It's connected. Nineteen to go."

We worked through the day, setting the slabs no more than 3 metres apart at the vulnerable crossing points, then extending the linked line around Strathmuir's broader perimeter according to the elders' map.

Some sites were easy to reach: the loch shore to the south, the moorland rise above the eastern houses and the rough ground behind the forestry depot. Others forced us along narrow tracks and into native woodland where I felt watched with every step.

At the seventh site, beside an abandoned forestry track, Calder stopped with one hand raised.

"Don't look directly at them," she said. "They're gathering."

From the corner of my eye, I saw pale figures between the distant trees. Their limbs were too long and their movements too fluid. They were not the solitary faceless mimic I had encountered during my first spring in Strathmuir. These were different - thinner, taller and moving in loose groups, their heads turning together as though directed by a single thought.

Other shapes stood behind them, too indistinct for me to understand.

"They know what we're doing," I said quietly.

"Yes. They'll try to stop us."

We placed eight slabs that first day. As we drove into the village at dusk, the street lamps seemed dimmer than usual and the shadows between buildings looked deeper.

A child's laugh echoed from an empty side street.

No children were outside.

"It's happening during the day now," I said.

Calder tightened her hands around the steering wheel. "The boundary is weakening faster than expected."

The second day was worse.

We managed to place six more slabs, but the resistance grew stronger. Whispers followed us everywhere. Sometimes they became so loud that they drowned out our own voices, forcing us to communicate by hand signals.

Twice we had to change our route when white-eyed women appeared at the exact sites marked on our map. They stood motionless over the frozen ground, their broad mouths open in silent smiles.

"They're learning," Calder said as we diverted around a dense stand of conifers where several long-limbed entities waited. "They're adapting to us."

The residents stayed inside. Those few who had to venture out moved quickly with their eyes lowered, following instructions passed through the village phone tree and Police Scotland's control room. I saw three black cats sitting in a row outside the village shop, each watching High Street with unblinking yellow eyes.

That night, something scratched at the door of my police cottage for hours.

The first knock came shortly after midnight.

I sat on the edge of my bed with my stab vest on, my radio and mobile beside me and the amulet clenched in one hand. I did not approach the door. I did not answer the voices that followed.

The scraping continued until dawn, sometimes at ankle height, sometimes near the top of the frame. Between each slow drag of unseen claws, voices whispered my name through the letter box.

At first they belonged to my parents. Then to the five people lost in August.

Dr Rahman's voice was the last.

"Dan," it whispered. "Please open the door. We found the Walshes."

I kept silent.

On 21 December 2025, the day of the winter solstice, we had six slabs left to place.

The sky never fully brightened. Strathmuir remained trapped in a grey twilight, and the temperature fell towards -15 degrees Celsius. That was bitter but plausible. What came with the frost-shapes was not.

As we drove to our first site, the temperature display on the dashboard plunged to -25 degrees Celsius in less than a minute. Dark forms moved between houses, leaving branching patterns of frost across windows and doors.

"Those are the same things that came during the January incursion," I said.

"The cold ones," Calder replied. "They shouldn't be out before dark."

They were not covered by one of the five rules. Strathmuir's residents had their own winter protocol: do not shine light directly at them, do not make sudden noise and do not watch them for longer than necessary. They reacted to attention as readily as they did to warmth.

Calder dimmed the vehicle lights and warned nearby residents through the Airwave radio and telephone network. We stayed inside the 4x4 until the frost-shapes moved on, then used the bonnet and open doors as cover while we carried the next slab to its position.

We worked faster after that, racing the darkness.

At the fourth site of the day, a faceless figure stepped directly into our path. This one was the solitary woodland mimic I remembered. It stood perfectly still over the place where we needed to dig.

I stopped at once.

"What do we do?" I whispered. Rule two demanded that I remain motionless before a faceless person in the woods.

Without moving her feet, Calder slowly drew the stone amulet from beneath her jacket.

"Hold yours up."

I raised mine.

The faceless figure took one step backwards. Its blank head tilted as if in confusion.

Calder edged forward with her amulet extended. The creature retreated again, then again, until the trees swallowed it.

"The amulets give us some protection while the circle is forming," she said. "But that won't work on everything, and it won't last for ever."

By late afternoon, eighteen slabs had been anchored. Two remained.

The sun had set behind the moor, and beneath the trees the darkness looked absolute. Whispers, scratching and childlike laughter followed us as we drove back towards the village centre.

"The final two go on opposite sides of the green," Calder said. "They close the circle."

Strathmuir looked abandoned. No lights shone from the houses and no smoke rose from the chimneys, although I knew approximately 420 permanent residents were sheltering inside, waiting for whatever came next.

We parked beside the village hall and saw the entities gathered around the green.

There were dozens of them. White-eyed women stood perfectly still, each with one unnaturally broad mouth. Faceless figures swayed behind them. Dark shapes flowed over the ground like living shadows.

Among them moved things I had never seen before: tall skeletal creatures with too many joints; small, child-sized figures whose red eyes glowed in the dark; hunched things crawling on all fours with their heads facing backwards; and humanoid shapes that altered whenever I tried to focus on them.

"They know these are the last stones," Calder said quietly. "They're trying to stop us closing the circle."

Inspector Reid emerged from the village hall with Mrs Fraser, Ewan MacRae, Hamish Sutherland, Moira Beaton, Elsie Munro, Alasdair Kerr and Margaret Singh. Each wore a stone amulet identical to ours.

"It's worse than 1995," Mrs Fraser said. Her voice remained steady, but fear showed in her eyes.

Reid pointed to the north and south ends of the green. Two shallow holes had already been prepared.

"Both slabs must be placed simultaneously," he said. "One at each end, at exactly midnight."

Moira checked her watch. "Seventeen minutes."

Calder took one slab. I lifted the other. Mine felt heavier than before, as if it were pulling towards the frozen ground.

"We'll distract them," Hamish said, raising his amulet. "The elders will walk the edge of the green and draw their attention. You two place the stones."

They spread out towards the perimeter.

Reid gave me a brief nod. "Good luck, Dan."

I watched him join the elders, straight-backed and determined despite the darkness gathering around him.

These people had done this before. Their families had guarded Strathmuir for generations.

Now it was my turn.

The elders began to walk around the green, holding their amulets high. Some of the entities turned to follow them. Others recoiled from the warm stones.

For a moment, the distraction worked.

Then darkness poured from the edge of the woodland.

It flowed between houses and across gardens like black smoke, yet it was thicker than fog. Street lamps dimmed as it passed. The air turned dense and painfully cold, pressing against my skin like a physical weight.

The whispers began as a hiss that might have been wind. Within seconds they surrounded us.

"Daniel," they called, first in my father's voice, then my mother's, then in voices I did not recognise. "Daniel, stop. Daniel, come home."

Mrs Fraser wrapped the leather cord of her amulet around her wrist.

"Don't listen," she warned. "They'll say anything."

The whispers became a chorus of dozens of voices speaking at once. I pressed my hands against my ears, but it made no difference. The sound was inside my head.

A high, childish laugh cut through it.

I had heard that laugh after dark in the police station and again while trapped in the locked supply cupboard during the October blizzard. The thing had never opened that secured door. It had not needed to. It could place sound wherever it wished, making laughter and scratching seem close enough to touch.

Now the laughter came from every direction at once, rebounding between the buildings around the green.

"There are more than before," Moira said. Her face had gone pale. "More than in 1995."

The entities advanced. White-eyed women gathered beside the buildings, their broad mouths stretching wider. Faceless figures moved behind them in jerky, unnatural steps. The new skeletal shapes bent at impossible angles, and the crawling creatures' red eyes reflected the failing street lamps.

Several of the white-eyed hunters reached the line established by the earlier stones. They pressed forwards and stopped as if they had struck an invisible wall. Pale hands spread against empty air. The darkness rippled around their fingers.

"The unfinished boundary is holding," Calder said.

A second rank of entities crowded behind the first.

"But they're pushing harder," Reid replied.

The pressure increased until my ears popped. The whispers became screams.

Moira looked at her watch. "Two minutes."

The elders moved more quickly around the green, calling the entities towards them without meeting their eyes. Hamish and Ewan held their amulets above their heads. Mrs Fraser struck hers against the iron railings, producing a clear ringing note that cut through the false voices.

The nearest entities turned towards her.

"Ready," Calder said.

I gripped my slab against my chest.

"Midnight," Moira called. "Now."

Calder and I ran in opposite directions.

I crossed the green towards the northern hole while she sprinted south. The laughter grew louder with every step. It changed from childish delight to an animal shriek, then back again.

I dropped to my knees and cleared loose frost and soil from the hole with my gloved hands. Across the green, Calder knelt over the southern site.

The entities noticed us.

Several white-eyed women turned away from the elders. Dark shapes slid across the grass. A tall, many-jointed thing unfolded itself and began moving towards Calder.

"Hurry!" Reid shouted.

I forced the heavy slab into place with its carved symbol facing upwards. The hole was shallow but deep enough to hold it. At the southern end, Calder lowered her stone at the same moment.

A white-eyed woman reached the edge of my peripheral vision. I kept my gaze fixed on the symbol.

"Daniel," she said in Calder's exact voice. "Help me."

Her broad mouth was still smiling. Calder was visible across the green, kneeling safely beside the other stone.

I did not answer.

I pulled my amulet from beneath my jacket and pressed it to the centre of the carved tree.

For one heartbeat, nothing happened.

Then the slab vibrated beneath my hands, sending a jolt through my arms. At the other end of the green, Calder's stone answered.

Cold blue-white light sparked from both symbols simultaneously.

It raced outwards along invisible lines, joining the buried slabs around the settlement. The white-eyed woman beside me screamed with a voice no human throat could produce and staggered backwards. All around the green, entities recoiled as the connected stones ignited one after another.

The light completed the circle.

It rose above Strathmuir and briefly resembled a vast curved veil, blue-white and translucent, drawn between the settlement and the dark beyond. Where it touched the gathered entities, their outlines buckled and tore like smoke in a gale.

The white-eyed women shrieked and retreated. Faceless figures jerked backwards as if dragged by unseen ropes. The skeletal creatures folded in upon themselves. The small red-eyed shapes crawled towards the woodland, their heads still twisted the wrong way round.

The child's laughter rose into a thin, furious wail.

The boundary pulsed once.

The nearest entities were thrown back from the green.

It pulsed twice.

The darkness between the houses withdrew towards the trees.

It pulsed a third time, brighter than before, and every remaining figure fled. Some ran upright, some crawled and others dissolved into streaks of shadow, but all retreated beyond the renewed boundary.

The whispers stopped.

The laughter ended.

The pressure in the air released so suddenly that I nearly fell forwards over the stone. I remained kneeling, breathing hard, as the blue-white veil faded to a subtle shimmer at the edge of my sight.

Across the green, Calder rose unsteadily. Exhaustion showed in her posture, but relief softened her face.

The elders gathered in the centre. Their amulets glowed faintly against their coats.

Reid came over and helped me to my feet.

"It worked," I said. My voice sounded too loud in the silence.

"Yes," he replied. "The boundary has been renewed."

"For another thirty years?"

"Until 2055, if the stones remain undisturbed and people keep the old obligations."

I looked towards the woodland. The unnatural darkness had receded, leaving only the ordinary blackness of a Highland winter night. The entities were gone, forced back to wherever they had come from.

But they had not been destroyed. They would wait beyond the boundary until it weakened again.

"Will the five rules work now?" I asked.

Mrs Fraser joined us. "They'll protect people as they have for generations, provided people understand what each rule is for. They lessen the risk. They don't make anyone invulnerable."

I touched the amulet at my chest. "And this?"

"Keep it," Reid said. "You're one of Strathmuir's guardians now. You've earned it."

The entities tested the fresh boundary for the rest of the night. Occasionally a shadow moved beyond the outer houses, or a pale hand appeared between the trees and pressed against something I could not see. None crossed.

We remained on the village green until dawn.

Grey light spread over the buildings and touched the frost on High Street. As morning strengthened, the last of the supernatural pressure faded. Birds began calling from the trees - ordinary birds making ordinary sounds.

The elders dispersed with the practised calm of people who had faced the darkness before and survived it. Reid walked part of the way with them, leaving Calder and me beside the final northern stone.

"Go home and get some sleep," he called back. "You've both earned it."

Calder watched the pale sky for a while.

"Now you understand," she said. It was not a question.

"Yes," I replied. "I do."

I looked down at the carved stone resting in my palm. When I had first arrived in Strathmuir on 6 February 2023, I would have dismissed it as superstition or evidence of a shared delusion. Now it felt like part of me - not merely a protective charm, but the weight of a responsibility I had accepted.

"This is why Strathmuir needs officers who follow the rules," I said. "We're not only protecting ourselves."

Calder nodded. "We maintain the separation every day in small ways. The five rules stop people feeding the worst dangers. The winter protocols deal with other things. The solstice renewal is the greater duty, but it all matters."

I tucked the amulet beneath my jacket and felt its warmth settle against my chest.

For nearly three years, I had watched this place test the limits of everything I believed. I had heard dead relatives call from empty rooms, stood motionless before a faceless mimic, refused the thing that knocked after midnight and fed a black cat without understanding why. I had seen the rules fail at their edges as the boundary weakened, and I had watched five people walk willingly into the woodland after voices they trusted.

Strathmuir existed beside something vast and hostile. People like Calder, Reid and the elders had spent their lives keeping watch over the place where the two worlds touched.

Now I stood with them.

"I need coffee," Calder said.

"I'll join you in a bit. I want to check something first."

After she left, I walked around the edge of the green and looked towards the native woodland where the entities had retreated.

In daylight, it resembled any other stretch of Highland forest: dark conifers beyond bare birch, frost over the undergrowth and birds moving among the branches. Nothing stirred below them but the wind.

I knew what waited beyond those trees.

The amulet would remain with me as a reminder of my duty to Strathmuir and its people. The boundary was secure. The five rules mattered again. The settlement had survived another turning of the cycle.

Thirty years would pass. In 2055, Strathmuir would need its guardians once more.

If I was still alive, I intended to be ready.
