Beyond the Closure

I left Aberdeen at 04:30 because that was what the job required. A mobile mast near Braemar needed a new antenna mount and some coaxial work before the weather worsened, and Scottish and Southern Electricity Networks wanted it finished by 12:00. That meant driving west on the A93 in the dark, which was fine.

I had done the journey probably a hundred times. The truck was a 2009 Ford Ranger work pickup with roughly 190,000 miles on it and a company logo I no longer bothered reading. White paint, rust around the wheel arches, a crack in the windscreen that had been there when they assigned it to me three years earlier. The heater worked.

That was the important thing in late November.

I had packed everything as I always did. Tool case behind the passenger seat, hard hat on the floor, two coils of coaxial cable secured beneath the load cover, and a company emergency flare launcher in the glovebox. I had carried that ever since being stranded on a Forestry and Land Scotland track during a Highland blizzard. A flask of coffee sat in the cup holder.

There was a petrol-station bacon roll I would eat somewhere near Braemar if I got hungry. It was routine. I liked routine.

The road was nearly empty at that hour. Just me and the occasional articulated lorry carrying whatever articulated lorries carried before dawn. I kept to a sensible speed for the A93 and the conditions, never over the posted limit, stayed on my side of the road and did not think about much.

The radio played a classic-rock station from Aberdeen until the signal faded beyond Aboyne. After that there was only static and the sound of the tyres on wet tarmac.

I did not think about Bethan Price. That was the point of taking jobs like this.

Stay busy. Drive somewhere. Fix something. Sleep in a Travelodge, drive back, repeat until going home did not hurt as much.

We had been together for two years and lived together for one. The break-up had happened three weeks earlier, and it had been messy in the way break-ups become messy when one person wants to talk about feelings and the other only wants to fix the problem. Except the problem, according to Bethan, was that I would not talk about feelings.

I reckoned I talked plenty, just not about the right things, apparently.

She had asked me to move out.

I did. I stayed in a Travelodge for four days, then began accepting every out-of-town call dispatch offered. There were always masts that needed work, always miles to cover, always a reason not to return to the flat I had rented after moving out. The one still full of unopened boxes because unpacking felt like admitting something I was not ready to admit.

So, yes. Braemar. Antenna mount. Coaxial work. Routine.

A weak orange glow began to gather beyond Aboyne. It did not provide much light, but where the mist cleared it was enough to let me switch off the headlights for a while. The landscape opened into Deeside moorland, all heather, broom, dark Scots pine, peat and granite outcrops. I did not mind it.

It was honest. It did not pretend to be anything it was not.

I passed through Dinnet without stopping. There was little reason to stop. The coffee was still hot and the bacon roll remained wrapped.

I kept my speed steady and watched the miles pass. Ballater came and went, the last proper town before the road climbed towards Braemar. A scattering of buildings, hotels and a petrol station that might have been open.

I did not need diesel. I had three-quarters of a tank, which was plenty.

About twenty miles beyond Ballater, everything stopped.

I rounded a long bend and saw brake lights. A lot of them.

Traffic filled the road ahead, cars and pickups sitting close together in both directions where vehicles had begun trying to turn. I slowed and stopped behind a silver Subaru with an unfamiliar English registration plate, then put the Ranger in neutral and applied the handbrake.

That was strange. The A93 did not get traffic jams out there, not at 06:00 on a Tuesday.

I could see perhaps ten vehicles ahead. Beyond them the road bent towards a broad lay-by, and there were shapes in the fog. Large shapes. Two olive British Army MAN HX trucks had been angled across the carriageway to form a barricade. Heavy transport vehicles with canvas-covered backs and mud flaps thick as chopping boards.

They blocked the road completely. The fog was too dense for me to see beyond them.

I switched off the engine and waited. Nobody moved. Nobody sounded a horn.

The man driving the Subaru simply stared ahead with both hands on the wheel. I assumed there had been an accident. Perhaps a chemical spill. That happened occasionally on trunk roads. An articulated lorry carrying industrial chemicals lost a tank, and the authorities closed the route until hazardous-materials teams cleared it.

A nuisance, but not impossible.

Then I saw the officer walking from vehicle to vehicle. He wore a Police Scotland road-policing uniform beneath a dark high-visibility jacket, with gloves and a peaked cap. He was probably in his late thirties, with a stocky build. Cold had reddened his face and his breath clouded in front of him.

At each vehicle he bent towards the driver's window, delivered the same short message and moved on.

When he reached the Subaru, I lowered my window a fraction so I could listen.

"There has been a hazardous-materials incident," the sergeant said. His voice was clipped and procedural. "The A93 is closed. You need to turn round and head east."

The Subaru driver said something I could not hear.

"No, sir. The road is closed. Turn round."

The driver tried again.

"Sir, I need you to turn your vehicle round now."

That was the end of it. The officer straightened and approached my pickup.

I saw him more clearly as he came closer. Square jaw, pale blue eyes and closely cropped fair hair beneath his cap. His identification marked him as Police Sergeant Callum Fraser.

He bent towards my window, and I lowered it fully.

"There has been a hazardous-materials incident," Sergeant Fraser said, repeating the script. "The A93 is closed. You need to turn round and head east."

"What kind of incident?" I asked.

"I can't discuss that. Turn round and head back towards Ballater. Take the B976 south via the Deeside back roads if you need a diversion."

"I've got a work order near Braemar. Mast repair. They're expecting me by 09:00."

"Call them and rearrange it."

His tone did not change.

"The road is closed."

I looked past him towards the trucks. The growing daylight had begun to thin the fog, and I could make out another figure behind the cordon. MTP combat clothing, body armour and a rifle. British Army, not Police Scotland.

"How long will it be closed?" I asked.

Sergeant Fraser's jaw tightened.

"Indefinitely. Turn round."

That was when I noticed his left hand, the one resting on the edge of my door. It was trembling. Not much, but enough for me to see it through his glove.

I looked back at his face. He was not merely irritated by traffic. He was genuinely frightened. He had the expression of someone trying to remain composed after events had already gone badly wrong.

"Is everyone all right?" I asked.

"Sir, I need you to turn your vehicle round now."

Behind him, the soldier was scanning the roadside in slow sweeps, left and right. His rifle remained pointed down but ready. He was just over 1.8 metres tall, broad-shouldered and hard-faced, moving through the fog near the verge while watching the heather and broom north of the road as though he expected something to emerge from it.

That troubled me. You did not watch empty moorland over a rifle unless you believed something was out there.

"What happened?" I asked.

Sergeant Fraser straightened. His hand left my door.

"Turn round and head east. That is your only option."

"I'm only asking."

"And I'm not discussing it. Turn your vehicle round or I'll have it removed."

There was an edge to his voice now. Not anger. Finality.

I looked at him, then at the Army trucks and the soldier still searching the fog-covered moor.

"All right," I said.

Sergeant Fraser stepped back and waited.

I started the engine. The Subaru was already beginning a careful three-point turn, and the vehicles behind me were leaving enough room for each driver to follow. Nobody argued. Nobody tried to force a way through. The entire queue simply began unwinding itself.

I waited while the Subaru completed its manoeuvre and drove east. The Vauxhall Insignia behind me held back to give me room, with a red Isuzu pickup waiting behind it.

I eased forwards and began my own turn within the carriageway, swinging the Ranger round slowly. As I did, I kept glancing towards Sergeant Fraser in the mirror. He had already moved to the next vehicle, his jaw tight as he repeated the same script. The soldier had not shifted his attention from the moorland.

That was what stayed with me, rather than the roadblock itself. Closures happened. Accidents, landslips, fallen trees, chemical spills. But the soldier was not watching the traffic.

He was watching the empty landscape, and Sergeant Fraser's hand had been shaking.

As the Ranger's nose came round towards Aberdeen, I saw movement beyond the military trucks.

Perhaps forty metres farther west, a deer fence followed the verge. Tall wire mesh, timber posts, the kind used to protect managed estate land. One section had collapsed. It had not been cut. A post leaned sharply towards the ground and the mesh sagged low enough for a vehicle to cross.

A white Toyota Hilux was already doing exactly that.

It crept over the damaged fence, tyres pressing the wire into the peat, then dropped onto a faint estate track which ran beside the A93 for perhaps twenty metres before curving north towards the River Dee. A dark green Nissan Navara followed it. Then a grey Mitsubishi L200.

Three pickups, one after another, slipping away from the public road as casually as if it were an established diversion.

I paused with the manoeuvre almost complete. The Vauxhall driver behind me sounded the horn once, a light tap to remind me he was waiting.

I did not move.

The L200 disappeared among the broom and heather. The track remained visible, no more than two ruts crossing the peat. It did not look public or maintained, but it existed, and those drivers had known where to find it.

Locals, probably. Estate workers or people who had grown up around Deeside and knew every back road between Ballater and Braemar. They were not prepared to wait for Sergeant Fraser to decide that the A93 was safe. They had work, appointments, lives.

I glanced towards the roadblock. Fraser was speaking to a driver several cars back. The soldier was still scanning the land beyond the opposite verge.

Neither was looking towards the gap.

I thought about the work order, the mast and the 12:00 deadline. Scottish and Southern Electricity Networks did not care about roadblocks or chemical spills. They cared about service uptime.

If I returned to Ballater and tried the B976 south through the Deeside back roads, it would add at least ninety minutes, perhaps two hours. I would reach the mast after 11:00, leaving barely enough time to mount the hardware, run the coaxial cable and test everything before the inspection window closed.

But if the estate track reached the river and joined an estate road running beside the Dee, it might eventually connect with another public road towards Braemar. I could still arrive around 09:00.

Plenty of time.

I completed the turn so the Ranger faced east with the others. Then, instead of following them, I slowed as though checking for traffic, changed direction deliberately and steered back towards the damaged fence.

The Vauxhall's horn sounded again, longer this time.

I ignored it, crossed the westbound side of the road and pressed the accelerator.

The pickup left the tarmac at perhaps fifteen miles per hour and struck the collapsed section. The front wheels bounced over the sagging mesh. The rear wheels followed, the suspension compressed, and then I was through and on the track, clods of peat flying behind me.

In the mirror, the Vauxhall sat motionless in the middle of its turn. Its driver's door opened and a woman stepped out. I think she stood there watching me.

I did not stop.

The track was rough, hard-packed earth broken by loose granite and ruts deep enough to rock the Ranger from side to side. I kept my speed around twenty miles per hour and held the wheel in both hands.

Heather and broom closed around the vehicle. Stunted Scots pines emerged here and there from the fog. It was the kind of country that appeared empty until you entered it.

Ahead, the white Hilux remained just visible through the churned peat, perhaps fifty metres away. The other two pickups had already vanished into the terrain. I assumed their drivers knew where they were going.

At the time, that was enough.

The track bent left and then right, following the contours of the land. The A93 disappeared behind me. So did the roadblock. There was only the pickup, the heather and the pale ruts passing beneath my tyres.

That was when the reality of what I had done settled on me.

I had left the controlled road, the official closure, the officer with the authority and the soldier with the rifle. I had crossed the boundary they had established and entered whatever area they were trying to keep people out of.

It was the first real commitment, the point after which the decision became harder to reverse.

I eased off the accelerator. Not enough to stop, only enough to think.

The track dipped gently towards the River Dee. I could see a dark strip of trees perhaps half a mile to the north, marking the water across the open moor. Fog filled the low ground. It was not the thin mist that had drifted across the A93, but something dense and wet, lying against the earth like a solid thing.

I entered it at fifteen miles per hour and visibility fell to less than ten metres.

The Hilux's rear lights glowed red ahead of me, then disappeared.

I slowed to ten, then five. Fog pressed against the windscreen. I could see the ruts immediately beneath the bonnet and a few metres of heather on either side. Everything else was grey.

The satnav was still on. Its blue dot, supposedly me, sat on an empty grid with no roads or labels. An icon revolved in one corner while the device tried to recalculate.

I watched it spin.

Then the map vanished. The screen turned blue.

NO SIGNAL.

Perfect.

I had worked in remote parts of the Highlands often enough to expect dead zones, but the timing was poor. I did not know this track, did not know where it went, and had no idea whether it joined the estate road by the river or ended at a locked deer enclosure.

Turning round was no longer practical. The track was too narrow, with soft peat on both sides, and I did not trust myself to reverse half a mile through dense fog without sinking into a ditch.

So I continued slowly, watching the ruts.

That was when the vehicle radio began to crackle.

It was not the FM station. I had lost that beyond Aboyne and had not bothered searching for another. This came from the dash unit itself, through the small speaker above the climate controls that usually produced nothing but static in places like this.

It crackled once, then twice, and a voice came through.

"Confirming grid NO 773 419. Advise Teams Two and Five to hold position until UAV coverage is restored."

A woman. Calm and professional, reading the grid reference with practised precision.

I frowned and reached towards the tuner, but did not touch it.

Her voice vanished. Static rushed in. Then a man spoke, faster and more forcefully.

"No headlights. I don't care what your visibility is. Kill the bloody lights and navigate by instruments."

More static.

I stared at the radio. It was not a broadcast station, and it was not ordinary vehicle-radio chatter. People did not use OS grid references or discuss UAV coverage over open road channels.

The woman returned.

"Understood. Relaying to all units. Harriet Cole confirming blackout protocol remains active until further notice. Repeat, no visible light sources beyond the inner cordon."

Static swallowed her again. Then the man returned, sharper than before.

"Major Stephen Blackwood to Team Three. If you are still running floodlights, you are compromising the entire western line. Shut them down now."

I let the Ranger roll to a halt.

The engine idled while the fog pressed against the glass. The radio continued to crackle. Harriet Cole read further grid references. Major Blackwood interrupted with instructions about equipment positions. A third voice, whose name I missed, reported a thermal contact beside the river.

Operational communications. That was what I had intercepted.

Nearby high-powered transmitters or some kind of interference must have been forcing their traffic through the vehicle radio, though I could not explain how. I had heard walkie-talkies bleed into other equipment at work sites, and once heard airport traffic through a site telephone, but this was different. These were organised teams discussing sectors, containment lines and blackout orders.

Whatever had happened beyond the roadblock was not simply a collision or chemical spill. It was active and ongoing.

I reached down and raised the volume.

Harriet was speaking again, directing UAV surveillance towards a northern gap.

Major Blackwood asked whether it was the same gap reported earlier or a fresh breach.

"New breach," she replied.

He swore, then ordered someone named Ross McKay to withdraw his team to the defensive position and wait for helicopter support.

I put the pickup in neutral, applied the handbrake and switched off the headlights. The fog swallowed everything beyond the windscreen.

I could not see the bonnet. I could not see the track. Only grey remained.

But I could listen.

The radio continued. Harriet Cole. Major Stephen Blackwood. A third, older voice asking about civilian traffic near the eastern checkpoint.

The eastern checkpoint. Sergeant Fraser's roadblock.

I sat in the dark and listened. They were tracking something. Multiple teams, UAV surveillance, helicopter support, inner cordons and checkpoints, and they did not want anyone using visible light.

The instrument panel still glowed a muted amber. It was not bright, but it was light. I turned the dimmer until the dashboard went black.

Now there was only me, the radio and the fog.

I do not know how long I sat there. Two minutes, perhaps five.

Then I heard it.

Not through the radio.

Something moved outside. Stems snapped in the heather to my left as something pushed through it, close enough to be within six metres of the pickup.

I froze.

The sound continued at a steady pace. Deliberate. Not the panicked flight of an animal. Something walking.

I leant towards the driver's window and peered into the fog. There was nothing but grey.

The noise moved parallel to the pickup, now perhaps five metres away.

I held my breath.

Then it stopped.

Silence, apart from the faint hiss of the radio and the soft ticking beneath the bonnet.

I waited.

The fog shifted, and something dark passed through it. A shape, tall and upright.

Then it was gone.

I remained rigid behind the wheel, heart hammering, fingers locked around the rim.

The radio crackled.

"All teams be advised, confirmed movement in Sector Nine. Repeat, confirmed movement."

I did not wait for the rest.

I released the handbrake, selected first gear and began rolling forwards with the engine still running but the headlights and dashboard dark. Five miles per hour, perhaps less. I could barely make out the ruts and did not know whether I remained on the track, but I was not staying there with that shape in the fog.

The mist thinned enough to reveal perhaps ten metres ahead just as the first red deer burst across my path.

A large hind led the herd, emerging from a dark backwater beside the river at a full run and crossing the track less than twenty metres in front of the Ranger without slowing. Five more followed, then another cluster of three or four.

They did not bound or scatter. They ran flat out with ears pinned and bodies low, holding a tight line towards the east.

I had seen frightened deer plenty of times while working on rural masts. Usually they scattered in every direction. These did not.

Perhaps fifteen crossed before the foxes came through.

Four of them, lean and red-brown, their tails held straight behind them. They followed the same route as the deer without so much as glancing towards the animals only ten metres ahead.

That was what frightened me.

Foxes did not run alongside deer. They hunted smaller prey or kept clear. But these animals were not hunting anything. Predator and prey were fleeing together from whatever lay towards the river.

I stopped counting and looked towards the place they had emerged from. All of them had crossed from my left, away from the Dee.

I leaned towards the side window and searched the fog. Nothing moved. There was only grey air and the black humps of heather.

The deer and foxes had already vanished to my right, heading east towards the roadblock, Sergeant Fraser and the Army trucks.

Whatever had terrified them remained behind.

I kept moving at less than five miles per hour. The radio had fallen quiet again, producing only static and an occasional pop of interference. My hands felt cold against the steering wheel despite the heater running.

Then the headlights caught metal.

I had switched them on without consciously deciding to, desperate to see the track as I moved away. Their beams found dark green paint through a break in the fog, then the square outline of a large vehicle.

I eased off the accelerator and coasted forwards another three metres.

An older Land Rover Discovery sat half-submerged in peat and river mud about fifteen metres from the track, its bonnet angled down towards the backwater from which the deer had fled. Both front doors stood open. The driver's door was wide and the passenger door halfway. The rear door remained closed.

I stopped, selected neutral and applied the handbrake, leaving the engine and headlights running.

It is difficult not to stop when you see something like that. An empty vehicle with open doors, sunk in mud. You stop because somebody may need help. They may be nearby. They may be injured.

I sat for perhaps twenty seconds, looking at it.

The Discovery's interior was dark. No courtesy light, no movement. Its front wheels had sunk so deeply that the bumper was buried, and the rear tyres appeared to have spun while the driver tried to reverse. Long furrows scarred the peat behind them.

Someone had pressed the accelerator to the floor.

I took the heavy four-cell torch from the passenger seat. It was black, with a dent in the end cap, and I had owned it since my first site job.

It worked.

I switched off the pickup. The engine ticked in the sudden silence and the intercepted radio traffic died with it.

When I opened the door and climbed down, the cold air smelt wrong.

Sour. Rotten. It was not the ordinary smell of river mud, wet peat or heather. It was the smell of organic decay, thick enough to taste at the back of my throat.

I pushed the pickup door nearly closed without latching it and switched on the torch. Its beam cut through the fog and struck the Discovery's open driver's door.

I walked towards it, boots sinking into soft ground. The mud was shallower than the patch that had trapped the Discovery, but wet and recently disturbed. The river must have risen through the braid not long before.

At three metres, I directed the beam into the cabin.

The driver's seat was empty. So was the passenger seat. Dark smears marked the steering wheel and the driver's door frame.

I moved closer and crouched beside the open door.

The stains were red-brown, partially dried blood, and there was a great deal of it. Bloody handprints covered the inside of the door. Finger marks dragged down towards the handle. Someone had gripped the frame while trying to pull himself free, and his hands had been bleeding.

From where I stood, I checked the passenger side. There was less blood there, only a few drops on the seat.

The keys remained in the ignition.

I stood and swept the torch around me. Nothing but fog and heather. I could not distinguish footprints in the churned mud, and nobody called for help.

The smell strengthened towards the river.

I did not want to follow it. That is the truth. I wanted to return to the Ranger and drive on, but I had already stopped and stepped outside. If someone had crawled from the Discovery and collapsed nearby, I could not leave without looking.

I moved towards the water, six metres and then nine.

A dark backwater and gravel braid lay beside the main channel of the Dee, separated from it by a narrow bank of shingle, scrub and dead branches. The backwater was perhaps five metres across. Its water moved darkly and slowly.

Then I saw the shape folded against the gravel bank.

Human. Too human to be mistaken for anything else.

But the angles were wrong.

I stopped.

The body lay on its side with its back towards me and its legs bent at the knees, but the torso had been twisted too far. The shoulders faced upwards while the hips faced the ground. The neck bent at an angle that made my own ache merely to see it.

I did not want to go closer, but I did.

The torch beam revealed an older man, perhaps sixty, wearing jeans and a brown waxed jacket. One arm reached towards the water. The other was trapped beneath him.

His face was gone.

Not gone. Opened, as if something had seized it and pulled it apart.

I stepped backwards.

My boot entered shallow water where the backwater had spread across the gravel, and icy wetness soaked through the leather.

The water beside the corpse began to move.

It was not flowing. It churned. Small waves struck the gravel in tight circles. There was no wind and the air remained perfectly still, yet the surface moved in a way that made no sense.

I turned the torch towards it.

For half a second, the beam caught something immediately beneath the surface. A shape, dark, long and close to the top.

A heavy splash sounded behind me.

I spun, sweeping the torch across the backwater.

Ripples spread from a point about three metres out, near the opposite bank. The water there had been violently disturbed. A sharp V travelled towards me, as if something large had submerged and begun swimming directly for the shore.

I backed away quickly without turning.

The wake kept coming. A straight cut through otherwise motionless water.

I struck the side of the Ranger hard enough for the half-open door to swing against my shoulder. The torch fell from my hand, landed in the mud and rolled until its beam pointed into the fog above.

I left it there.

I hauled myself into the cab, slammed the door and turned the ignition. The engine caught. I switched on the headlights, and white beams flooded the backwater.

The ripples had stopped.

The water was flat and apparently empty.

I sat breathing hard, both hands locked around the wheel.

The powered radio crackled back into life.

"We have a breach at grid NO 771 423."

Major Blackwood. The same voice as before, but louder and urgent now.

"Pull everyone back to the visitor centre. Do you copy? Hold the line at the visitor centre."

Another voice cut in. Harriet Cole, I thought.

"Understood, Major. Team Three is en route. ETA four minutes."

"Negative. We don't have four minutes. I need personnel at that position now."

"They're moving as fast as they can."

"Tell them to move faster."

The visitor centre.

I knew the estate had one somewhere near the river. A fictional-looking modern building tucked into the managed landscape, used by the National Trust for Scotland for visitors, ranger operations and guided walks. I had seen its signs on previous journeys but had never stopped. If the estate track continued towards it, that was where the people and the defensive line would be.

I selected first gear and pressed the accelerator.

The Ranger lurched forwards. Its tyres spun briefly in the mud, caught, and drove me back onto the rutted track. About thirty metres ahead, the route curved north away from the backwater.

I followed it.

The fog was thicker there, but I did not slow as much as I should have. Somewhere behind me, in that dark water beside the mutilated man, something had been swimming towards the bank.

I kept moving towards where I thought the buildings must be.

The pickup hammered over ruts I could not see. Visibility rose to twelve metres, fell to nine, then narrowed further. The track bent left. I followed it, tyres throwing mud against the wheel arches.

Major Blackwood's voice broke through the radio again.

"Team Three, report position."

A younger man answered.

"Half a mile out. Track conditions poor."

"Push through."

I did not know what I was pushing towards, only what I was leaving behind. The steering wheel bucked whenever a front tyre struck granite or a buried root, and I corrected without stopping. My headlights bored white tunnels through the grey. I kept my eyes fixed on the ruts ahead and ignored the shapes that seemed to shift at the edges of the beams.

Fog and heather. Probably.

The track straightened, and something solid appeared ahead.

I eased off the accelerator and stopped about five metres short of a gate.

It was a National Trust for Scotland estate gate across the service track, a heavy green-painted steel frame with wire mesh through the centre. A padlock almost the size of my fist secured the latch. Reflective yellow strips marked the posts.

A wooden sign fixed to the left post read:

AUTHORISED VEHICLES ONLY

Beneath it, a smaller metal notice warned about restricted National Trust for Scotland estate land, permits and penalties. I did not read the details.

The track ended at the gate. Beyond it, an estate road continued into the fog, but I could not see far enough to know where it led.

Behind me lay the backwater, the body and whatever had made that wake. Ahead stood a locked gate and restricted land.

I put the pickup in neutral, applied the handbrake and rubbed my face with both hands.

My fingers smelt of mud and the rusty edge of the Discovery's door frame.

The radio crackled.

Harriet's voice said, "Perimeter holding at the centre. No movement in Sector Six."

"Understood," Major Blackwood replied. "Keep the floodlights off."

I stared at the padlock.

Bolt cutters would have opened it in seconds. Mine were inside the tool case behind the passenger seat. I had used them two weeks earlier at a site near Montrose when the access lock had rusted solid and nobody could find a key.

Getting them would still mean stopping, opening the cab and stepping outside into the fog.

I checked the rear-view mirror. Nothing but grey and the muted reflection of my rear lights.

I selected reverse and let the pickup roll back about a metre.

The rear sank.

The tyres spun with the high whine of rubber searching for purchase and finding only mud. I increased the power. The whine grew louder, but the Ranger did not move.

Stuck.

I eased off and tried rocking it. First gear, reverse, first again. The front wheels found some grip, but the rear wheels merely spun, and I could feel the pickup settling deeper into the peat.

"Come on."

I tried once more. Nothing.

I was about to return it to neutral when something struck the pickup from behind.

It was not a collision. It was a dull, heavy thump, like a sandbag dropped onto the tailgate. The whole chassis rocked forwards.

I looked into the rear-view mirror.

At first I could not understand what I was seeing.

The tailgate was closed, but something pale hung over its top edge.

An arm. That was what my mind called it, though it was too long and bent at the wrong places. Its grey-white flesh resembled meat that had been frozen and thawed. At the end was a hand with three thick fingers and no visible nails, only blunt tips.

I stopped breathing.

The arm slid backwards and disappeared.

Then a face filled the rear window.

Grey skin, the same colour as the arm. No eyes that I could see, unless they were buried so deeply that the sockets appeared empty. Only dark hollows.

Its mouth opened.

No sound penetrated the glass, but I watched the jaws spread far wider than they should have. The interior was black and wet. Thick fluid smeared the window as the head moved.

I tore open the glovebox.

The company emergency flare launcher lay beneath the vehicle documents and a tyre-pressure gauge. Orange plastic, single-shot and loaded. I had checked it about six months earlier, and it had remained untouched ever since.

I grabbed it and twisted in my seat.

The small sliding panel in the centre of the rear window opened for ventilation. I shoved it sideways with my free hand. It jammed halfway. I struck it with the heel of my palm and forced it fully open.

The face remained against the glass, its mouth still spread wide.

I thrust the flare launcher through the gap and pulled the trigger.

The recoil was slight, but the report inside the cab was deafening.

There was a crack, a hiss and an eruption of red light. The flare struck what I took to be the creature's shoulder, glanced away and landed in the mud behind the pickup. It continued burning, an intense red glare illuminating several metres of fog.

The creature recoiled from the window, fast but not panicked.

It did not fall or stumble. It simply moved away from the heat and light, repositioning itself, and for half a second the flare revealed more of it.

It stood just over two metres tall. Thin, but not frail. Its proportions were wrong.

Long arms, long legs, a torso too short or too narrow. It stepped to the left and the fog swallowed it.

I sat there with the empty flare launcher still pointing at the window, my hand shaking hard enough for the plastic casing to rattle against the glass. Then I heard it clicking - fast, rhythmic and organic. It was like someone snapping their fingers over and over, only wetter, accompanied by something almost like a hoot.

I cannot describe it any better than that. A hoot, but forced, as though it were being driven through metal or a narrow pipe. It was so low that I felt it rattle inside my chest.

Another hoot answered from farther out in the fog, perhaps thirty or forty metres to my right.

There were two of them.

Major Stephen Blackwood's voice came through the vehicle radio.

"Kill your headlights. They're tracking the light."

I did not think. I reached down, turned the switch and extinguished the headlights and dashboard illumination. Then I twisted the key and killed the engine. The heater fan died with it.

Everything went quiet. There was no engine rumble, no warm air blowing through the vents, only my breathing and the faint hiss of the flare still burning somewhere behind the pickup.

I sat in the darkness and listened.

The clicking had stopped. There was no more hooting, just silence and fog pressing against the windows.

My mobile was on the passenger seat. I picked it up without taking my eyes from the rear-view mirror. The screen lit, showing one bar of signal in the corner. I watched it flicker, drop to nothing, then return to one. I opened the keypad and the screen went black.

Dead.

I pressed the power button. Nothing. Not even the battery symbol.

It had been at thirty per cent when I checked it at the roadblock, perhaps forty minutes earlier. I put it down. My power bank was in the tool case.

An external charger, 20,000 mAh, bright blue, made by Anker. I had bought it on offer at B&Q and charged it fully the day before.

It was right there beneath the load cover, with the bolt cutters, wire strippers and everything else I could not reach without leaving the cab.

I looked into the side mirror. The flare was still visible as a red glow behind and to the left, dimmer now, perhaps five metres away. It illuminated the peat, mud and a patch of heather, but nothing beyond them.

There was no movement. I could not see either creature.

Major Blackwood's words kept circling in my head.

Kill your headlights. They're tracking the light.

I had done that. Lights off. Engine off. Radio silent now that the ignition was dead.

I sat in the darkness. If they tracked light, they probably tracked sound as well. The diesel engine had been loud. The flare launcher had been louder.

But I was quiet now. Perhaps quiet enough.

I put the empty launcher on the dashboard and wiped my palm on my jeans. My hand was still shaking.

The tool case was perhaps two and a half metres from the cab. Less, if I climbed over the side of the load bed. I would have to open the door, climb out, move to the back, release the load cover, undo the straps and case latches and find what I needed. Thirty seconds if I was quick. A minute if I was not.

A minute in the open with my back exposed and two of those things somewhere in the fog.

I looked at the gate again. It was still locked, still blocking the only way forwards.

The flare behind me guttered and went out. Full darkness settled over the pickup. I could see nothing except the vague outlines of the gateposts and the slightly paler grey of the fog.

I sat there and tried to think.

A torch beam cut through the fog from the other side of the gate.

I ducked low in the seat, my hands braced against the dashboard. The beam swept left, then right, then settled on my windscreen. I could not see who was holding it, only the white light, the fog and the chain-link panel between us.

Someone shouted. It was a man's voice, muffled by the glass and mist, but I could not make out the words.

The beam dropped to the ground. A figure moved behind the gate. Boots scraped on gravel and chains rattled through metal. Then the gate swung slowly inwards, just wide enough for someone to step through.

The figure came forwards into the narrow space between the gate and my pickup.

He wore the outdoor uniform of a National Trust for Scotland ranger. A rifle was slung across his chest, its barrel angled down. He raised one hand, palm out, fingers spread. With the other, he kept his torch aimed at the ground between us.

He made one sharp gesture, pressing a finger to his lips.

I nodded.

He pointed towards the gap in the gate, then at me, then through the gap again.

I understood. Get out. Come through. Do it quietly.

I grabbed the empty flare launcher from the dashboard and pushed it into my jacket pocket. I left the dead mobile on the passenger seat and opened the door as slowly as I could, trying not to make the hinges creak.

They creaked anyway.

I stepped down into the mud and eased the door shut without allowing the latch to catch. The ranger stepped back and kept the beam low. I walked towards him, my boots sinking into the wet ground with each step.

The fog pressed in from every side. I could not see more than three metres.

I reached the gate and slipped through the gap. The chain hung loose from one side, still padlocked at the other. He had freed it from the post without opening the lock.

He put a hand on my shoulder and pulled me close. His breath was warm against my ear.

"Don't talk," he whispered. "Don't run. Follow me, and step where I step."

I nodded again.

He turned and began walking. I followed him along a gravel service road that I could not see until my boots were on it. He kept the torch pointed at the ground less than a metre ahead, showing only the edge of the track.

The fog swallowed everything else.

My heart was still hammering from the pickup, from the thing at the tailgate, from the clicking and hooting and the arm that bent the wrong way. The ranger moved quickly but carefully, making remarkably little noise.

I tried to match his pace.

After perhaps thirty seconds, he spoke again, still in a whisper.

"You came from the A93?"

"Yes."

"Through the deer fence?"

"Yes."

"Jesus."

He did not sound angry, only exhausted.

"How many vehicles got through?"

"I saw three ahead of me. Maybe more."

The Toyota Hilux, Nissan Navara and Mitsubishi L200 had all been ahead of me when I took the track. I had seen no sign of them since.

He did not answer. He kept walking. The gravel crunched softly beneath our boots, a small sound that seemed far too loud.

I wanted to ask where we were going, but he had told me not to speak.

After another twenty metres, he slowed and glanced back at me. He was young, in his late twenties perhaps, with dirt smeared across one cheek and hard, exhausted eyes.

"There is aggressive wildlife near the river," he said in a clipped whisper. "The road closure wasn't because of a chemical spill. It was a containment cordon to keep civilians out of the area."

I took that in.

"So the roadblock was supposed to work."

"You broke through it."

I had no answer.

He faced forwards and increased his pace.

"Stay close. Don't touch anything. Don't shine a light. Don't make noise."

"All right."

We continued. The fog began to thin, and low, rectangular shapes emerged ahead of us.

Buildings.

"What's in the river?" I asked.

He did not answer immediately.

"I don't know. Nobody does. But it's fast, it's intelligent and it doesn't stay in the water."

That matched what I had seen: the arm, the face, the way it moved.

"How many people are here?"

"Not enough."

The service road opened into a car park of dark tarmac and faded white markings. The fog was lighter in the open space. I could see perhaps fifteen or twenty metres.

The visitor centre stood on the far side. It was a low, single-storey estate building with broad front glazing and granite facing along the lower half. National Trust for Scotland signs identified the surrounding land, but the centre itself bore only the fictional estate's name. Lights burned inside, though most of the windows had been covered with tarpaulins.

The car park was full of vehicles: estate pickups, several quad bikes and a large transport van with its rear doors open. Portable lighting stands had been placed near the entrance and aimed outwards, but only half were switched on. Equipment lay scattered everywhere - plastic cases, folded tarpaulins and a trestle table tipped on its side.

It looked like an emergency base that had been assembled in a hurry and was disintegrating faster than anyone could manage.

The ranger led me towards the entrance, keeping close to a line of concrete planters along the footway. He crouched behind one and pulled me down beside him.

A woman stepped from behind the next planter. She was in her mid-forties, perhaps, with dark hair pulled tightly back and a supervisor's badge on the sleeve of her estate-ranger uniform. She held a handheld radio in one hand and a pistol in the other.

She looked at me, then at the young ranger.

"Who's this?" she asked, her voice low and edged with anger.

"Civilian," he said. "Came through the eastern deer fence. I found him trapped at the service gate."

She stared at me.

"You drove through the fence?"

"Yes."

"Past the roadblock?"

"Yes."

She shook her head but said nothing more. Instead, she turned and thrust the radio towards the young ranger.

"Euan, stop transmitting. Listen only."

Euan Grant took the radio.

"Why?"

"The clicking. They respond to radio activity. Every time we transmit, they move closer."

Something cold seemed to drop through my chest.

The vehicle radio. The voices of Major Blackwood and Harriet Cole. I had sat in the pickup listening to intercepted operational traffic the whole time, though there was no ordinary reason my equipment should have been able to receive it. Nearby high-powered transmitters or some form of interference might have forced the signal through. Whatever the explanation, the creatures had reached me while the set was active.

"They track it," I said.

The supervisor looked at me.

"The radio," I continued. "Electrical noise, perhaps. They follow it."

She tilted her head slightly.

"How do you know?"

"Because they came to my pickup while the radio was on."

Euan looked at her.

"Fiona, if that's true, we've been advertising our position this entire time."

Fiona MacLeod looked at the radio in his hand, then at the portable lights and back at me.

"What else attracts them?"

"I don't know. Light, certainly. Sound and movement, I think."

She nodded once, already considering what could be shut down.

Then something struck the tarmac six metres away.

It landed with a heavy, wet impact, like a sack of sand dropped from a roof.

All three of us turned.

A body lay face down with its arms spread wide. It wore estate field clothing, and a dark stain was spreading beneath the torso. I saw the name badge.

Gareth Hughes.

I had worked with Gareth two years earlier on another contract job. Different site, same company. He had been reliable, quiet and decent. The sort of man who checked your harness without being asked and never left another engineer to pack up alone.

His throat was gone, torn open. One side of his face had been crushed and his jaw hung at the wrong angle. There was blood everywhere.

Euan started forwards, but Fiona caught his shoulder and dragged him back.

"Don't," she hissed.

Something stepped into the light.

It was just over two metres tall, with pale grey skin that gleamed as though wet. Its arms were too long and its joints flexed backwards. Each hand had three elongated fingers. I could see no eyes, only smooth skin and shallow hollows where eyes should have been. Its mouth gaped wider than a human mouth could, black inside.

It bent, seized Gareth by the ankle and dragged him backwards into the fog.

His body slid across the tarmac, leaving a wet, dark-red trail beneath the lamps. The sound was appalling - fabric and skin scraping over the road surface. Gareth's arm flopped once before the mist took him.

Euan raised his rifle, but Fiona pushed the barrel down.

"Hold."

More shapes moved along the edge of the car park. Four, five, perhaps more. The fog made counting impossible. They did not enter the strongest light. They circled it slowly and deliberately.

Then the clicking began, fast, rhythmic and wet, surrounding us.

Fiona pulled us both back towards the entrance.

"Inside. Now."

The first creature did not charge. That was what struck me.

It slid into the car park on its arms, hauling itself forwards with those two long limbs rather than running. Its legs trailed behind. They were not useless, but they did not lead the movement. A second creature appeared to the left and moved in the same smooth, deliberate fashion.

They crossed the tarmac like people moving over ice they did not trust. I could not look away from their arms. The joints folded in the wrong direction, straightening and bending in a rhythm unlike anything I had ever seen.

There were too many of them. Or perhaps it only felt that way. Either way, we could not hold the open ground.

Fiona raised two fingers, then pointed towards the visitor-centre entrance.

Euan began moving. So did four people I had not noticed sheltering farther along the planters, all dressed in estate gear and keeping low. One woman limped. A man held one hand against his ribs.

The glass doors were six metres away, perhaps less. Fiona waved urgently.

"Go. Go now."

They ran. Boots struck the tarmac and breaths came loud and ragged. Nobody tried to remain quiet any longer.

The entrance doors had broad metal handles and push bars. Euan reached them first and forced his way through. The limping woman followed, then the man clutching his ribs.

The creature on the left released a low, wet hoot, the same sound I had heard in the fog. The creature on the right answered.

Then the glass exploded outwards.

Not the doors through which Euan had just passed. The broad windows on either side buckled, crazed and broke into heavy sections of safety glass that crashed onto the concrete footway.

A third creature stood inside the building, framed by one of the ruined windows.

It had been in there the entire time.

Someone screamed. I never knew who.

The limping woman stumbled backwards and struck the tarmac. The injured man turned to help her, but Fiona was already moving, catching the woman's arm and hauling her upright.

I did not think.

I ran, but not towards the entrance.

I ran for my pickup.

The gate was still open behind me and the service road was empty. My Ford Ranger stood where I had left it, stuck in the mud with the driver's door resting against the latch.

I sprinted past the planters and light stands, across the car park and onto the gravel. When I reached the mud, it caught one heel and nearly brought me down, but I kept going.

The load cover was rigid and secured at the tailgate. I released one latch, then the other, lifted the cover fully and braced it with its support rod.

My tool case sat beneath it, strapped to the bed with a bungee cord. I tore the cord free and opened the latches.

Inside were wire strippers, crimping tools, a spanner set, voltage tester, electrical tape, cable ties, two coils of coaxial cable and an aerosol can of contact cleaner that I used on connector threads.

I grabbed the contact cleaner and pulled at one of the coils of coax.

Something struck the tailgate so hard that the entire pickup lurched forwards.

I spun round.

The creature was directly behind me. One hand gripped the tailgate while the other reached for my leg. Its three fingers were too long. They had no nails, only smooth, blunt grey tips.

I snatched my leg into the bed. Its hand missed me by centimetres.

The creature hauled itself closer, levering its weight against the tailgate. The rear suspension sank beneath it.

I rolled to the left, dragging the coil after me, then lost my grip and fell over the side of the load bed. My shoulder struck first, then my hip.

The contact cleaner remained in my hand because I refused to let it go. A short length of coax, torn from the coil during the fall, had looped around my wrist. I ripped it free and shoved it into my jacket pocket before scrambling beneath the rear bumper and pressing myself flat into the mud.

The undercarriage hung immediately above me: axle, differential and an exhaust still warm from the drive.

On the far side, I saw the creature's legs dragging forwards as it climbed into the bed. The tool case rattled. Metal clanged against metal.

It was going through my equipment.

I heard Fiona shouting. I could not make out the words, only the urgent tone of someone ordering another person to act immediately.

Three gunshots followed.

Crack. Crack. Crack.

A pistol, not a rifle.

Then Euan's voice, higher with strain.

"Left! Left!"

More shots. The deeper report of his rifle echoed across the car park.

A hoot answered from somewhere beyond the visitor centre. Another followed farther away, perhaps near the estate road.

More were coming.

The creature in my pickup shifted its weight. The suspension creaked above me. Then it dropped from the passenger side and vanished from my limited view.

I did not wait.

I rolled from beneath the bumper, forced my feet under me and ran.

The maintenance shed stood at the edge of the car park between two large bins. It was a small structure, roughly three metres square, clad in metal painted a dull estate brown. The door had a padlock, but the hasp was bent and hanging loose. Someone had already forced it.

Or something had.

I seized the handle and pulled. The door swung open.

Shelves inside held cleaning supplies, a mop bucket, a stiff broom, stacked traffic cones and emergency estate equipment. Among it was a cardboard box containing railway-style red warning flares.

I opened the box. There were six inside, the sort ignited by removing and striking the cap. I took two.

Then I saw a large container of winter screenwash on the bottom shelf. Blue liquid, nearly full. Highland winter mixture, strong with alcohol.

I grabbed that as well. The contact cleaner was still in my other hand, an aerosol marked highly flammable.

I put everything on the concrete floor and pulled the short length of coax from my pocket. The main coil was gone, left in the load bed, but I had perhaps a metre of cable.

Its outer jacket was tough. The braid itself would not burn in any useful sense, but the plastic and dielectric foam would melt and catch once the alcohol and solvent ignited around them.

I twisted the cable into a loose coil and soaked it with screenwash. The sharp alcohol smell hit me at once. Then I sprayed contact cleaner across it, coating the jacket and braid.

It was not a weapon anyone sensible would have trusted. It was a handful of cable drenched in two flammable chemicals, one of them pressurised, and I was preparing to hold it close to my own body.

I removed one warning flare, twisted off the cap and struck it.

The flare hissed, sputtered and caught. Fierce red light filled the shed, hot enough to make me turn my face away.

I touched it to the coil.

The solvent vapour ignited immediately. Blue and orange flames writhed over the cable, unstable and flickering. The braid began to glow. The plastic jacket bubbled and melted, dropping burning beads onto the floor.

I lifted the blazing coil with both hands. Heat bit into my palms, but I held on.

Something moved in the doorway.

I looked up.

A creature stood there, just over two metres tall. Its pale grey skin shone with slime or river water. There were hollows where its eyes should have been, and its mouth opened far wider than its skull seemed able to permit.

Inside were uneven teeth, sharp and broken-looking, like splintered nails.

It stepped forwards.

I thrust the burning coil into its mouth.

Its head snapped back. Both hands flew to its face, clawing at the fire.

It made a sound I had never heard before. Not a hoot and not the clicking. A wet, rattling shriek that went on and on.

It thrashed against the doorframe and shelves. Bottles and cleaning supplies crashed to the floor. The mop bucket overturned and rolled away.

The smell changed.

Burning flesh. Melting plastic. Beneath them, something chemical and acrid.

The creature staggered backwards out of the shed, still shrieking and tearing at its face. Fire spread across its mouth and into the hollows where its eyes should have been. It dropped to its knees, then fell onto its side.

It continued to move, but more slowly.

The flames did not go out.

I stepped from the shed. My hands were trembling, and the smell was everywhere.

More hoots sounded nearby. Not one or two now, but four or five, all answering the shriek and converging on the fire.

The weapon had worked, but it had also told every creature nearby exactly where I was.

Fiona appeared from behind a concrete planter, moving at a run. She caught my arm and wrenched me sideways.

"Move!"

Two creatures struck the shed wall where I had been standing. The impact dented the metal cladding and cracked the masonry beneath it. Dust burst from the point of collision.

The second warning flare was still in my pocket. I pulled it out, twisted off the cap and struck it.

It caught immediately.

Fiona shoved me towards the visitor centre.

"Keep it lit!"

I raised the half-full can of contact cleaner. One of the creatures peeled away from the wall and turned towards us, its long arms reaching.

I held the flare out and sprayed the aerosol through the flame.

The contact cleaner ignited in the air, producing a roaring jet of orange fire almost a metre long. It swept across the creature's extended arms. Its skin blistered and blackened at once.

The creature recoiled with a hoot, but another stepped into its place.

"Go!"

Fiona was supporting the woman who had fallen earlier. I caught a brief glimpse of her badge.

Kirsty Bell.

Blood covered one leg. Fiona had an arm around Kirsty's waist and was carrying much of her weight.

I sprayed the contact cleaner again. Flame swept left and then right, buying us perhaps five seconds.

Fiona dragged Kirsty through a side entrance, away from the shattered main glazing. It was a metal maintenance door fitted with a push bar, and it was already open. Euan stood inside, holding it with one hand and his rifle with the other.

"Come on!" he shouted.

I backed towards the entrance and sprayed once more. The aerosol can sputtered, almost empty.

Then I turned and ran the last three metres.

Euan caught my shoulder and dragged me across the threshold. I stumbled inside. He slammed the door behind me and threw the deadbolt.

Something hit the metal once, then again. The panel bowed inwards but held.

The hooting began directly outside. The clicking joined it, fast and rhythmic, coming from several directions.

Inside, there was only emergency lighting: red exit signs and a few battery lanterns turned down low. People sat against the walls.

Five at first glance. Then six.

I counted again. Six.

Fiona knelt beside Kirsty, pressing a folded jacket against the wound in her leg. Kirsty's face was pale, but she made no sound.

Euan moved past me and crouched beneath one of the remaining windows. Its glass was intact, though covered from inside with tarpaulin. He lifted one edge by a centimetre, looked out and let it fall.

Nobody spoke.

The hooting circled the building. The clicking moved with it, as though the creatures were testing the walls and searching for another entrance.

Smoke drifted through the room. I could smell burned plastic, scorched cable and something worse beneath both.

My hands began shaking again.

I looked down. Blisters covered both palms, red and white and already swelling.

I sat against the wall. I did not choose to sit. My legs simply failed and left me there.

The sounds continued outside for hours.

The hooting would stop for a time and then begin again. The clicking never entirely ceased. It moved around the visitor centre, circling and waiting.

We kept the lights low. Nobody talked unless it was unavoidable. Several people had radios, but Fiona ordered them switched off completely. No transmissions. No electrical noise we could prevent.

As the winter morning strengthened towards full daylight, the hooting began to thin. I could not see outside, but I heard the difference. There were fewer calls, and the clicking gradually withdrew in the direction of the River Dee.

Perhaps the creatures were returning to the dark backwaters and gravel braids from which they had emerged. Perhaps they were only moving out of earshot.

Fiona stood. She had been beside Kirsty for hours. She looked around the room, counting. Her lips moved, but she did not say the number aloud.

Euan remained by the covered window. His sleeves were stained with dark, dried blood, but it was not his. He had carried casualties - Kirsty and others - while the creatures closed in.

I looked at my hands again. The blisters had worsened.

I could not remember when I had dropped the warning flare. Somewhere between crossing the maintenance threshold and collapsing against the wall, probably. Wherever it had fallen, someone must have smothered it before it could set the building alight.

Fiona walked to the main entrance. The doors remained in place, but the surrounding frames and glazing had been destroyed. Broken glass lay everywhere, and the entrance was now an open breach rather than a secure doorway.

She looked out through the gap, then turned back.

"Gareth didn't make it," she said, flatly, as if merely reporting a confirmed fact.

He had already been dead when his body struck the car park, but hearing it said made the certainty worse.

"Neither did Peter Lang."

Nobody answered.

Several people lowered their heads. One woman pressed a hand over her mouth. Euan did not move. He continued staring at the tarpaulin covering the window.

I thought about going outside to inspect my pickup. Then I realised I did not care.

It was probably gone anyway - dragged away, rolled or torn apart. I had left the driver's door unlatched and the load cover raised. Nearly everything I needed for my work was in that vehicle, yet I could not make myself care about any of it.

Heavy diesel engines sounded outside. Several vehicles, approaching together.

Fiona returned to the ruined main entrance and looked through the breach. Then she stepped aside.

Police Sergeant Callum Fraser entered first. He was the same road-policing sergeant who had faced me at the A93 checkpoint in the darkness, though he now carried a rifle and wore additional protective equipment. Behind him came two authorised armed response officers, followed by four British Army personnel in MTP combat clothing and tactical kit.

Sergeant Fraser saw me sitting against the wall. His expression did not change. He looked at me for a moment, then turned to Fiona.

"Building secure?"

"For now," she said.

He nodded and spoke into the radio on his shoulder. I did not catch the words.

More people entered through the broken frontage. Paramedics went directly to Kirsty. One looked at the blood on Euan's sleeves and tried to examine him, but Euan waved him away.

I stood. This time my legs held.

I walked towards the breach. One of the armed officers stepped in front of me.

"Sir, you need to remain inside."

"I'm leaving."

"Let him go," Sergeant Fraser said.

He stood near the entrance, watching the car park. He did not look at me.

The officer moved aside.

I stepped out into the morning.

The sun was fully above the horizon, low and orange, cutting through the last remnants of fog. Portable lights lay overturned. Cases, cables and other equipment were scattered across the car park.

Gareth's body was gone. Someone had already recovered it from wherever the creature had dragged him.

My pickup was no longer where I had left it.

I followed the service road towards the gate and found the Ford Ranger off to one side, nose-down in a ditch. The load cover had been torn away completely. The tool case was gone, along with both coils of coaxial cable. Tools lay scattered through the mud and heather.

My hard hat rested near the gate. I picked it up. There was a deep dent in one side.

I could not remember losing it. I put it on anyway.

My jacket stank of smoke and contact cleaner. The left pocket was torn. The right still held the empty company flare launcher I had carried ever since being stranded during a Highland blizzard.

I walked back towards the visitor centre.

Sergeant Fraser was talking to Fiona near the breached entrance. He saw me approaching and stopped halfway through a sentence.

I said nothing. Neither did he.

I had driven through the deer fence and past a roadblock into an area the authorities had closed for a reason. I had done it because I had a work order, a 12:00 deadline and no wish to lose hours taking the diversion along the B976 south via the Deeside back roads.

Now Gareth Hughes was dead. Peter Lang was dead. Kirsty Bell might lose her leg or worse. Everyone else had spent hours trapped inside a building surrounded by things that should not have existed.

My powered pickup, its lights and the abnormal radio traffic had probably drawn at least some of the creatures towards the visitor centre. The centre had already been under attack. The containment zone had already been failing before I arrived. I knew that.

But knowing it did not loosen the guilt.

I had always preferred problems I could fix with tools. A damaged connector. A dead battery. A broken fence. A road closure I could solve by finding my own way around it. Anything practical was easier than admitting fear, failure or regret.

This time, my solution had carried the danger with me.

I walked past the armoured vehicles, the armed officers securing the perimeter and the British Army MAN HX trucks positioned along the estate road. I passed Euan, who was sitting on the rear bumper of an estate vehicle with his head in his hands.

Nobody stopped me.

I reached the service road before I understood that I had nowhere to go.

My pickup was wrecked. My tools were gone. My mobile was dead.

I stopped walking and stood there.

The hard hat felt heavy. The blisters on my hands burned.

Sergeant Fraser's voice carried across the car park as he issued orders and tightened the cordon, reducing what had happened to sectors, defensive positions and an incident scene that could still be contained.

Perhaps that was what it had to be for him.

For me, it was the consequence of a choice I could never undo.
