The Fog on Loch Arkaig

I drove into Fort William on a Tuesday morning expecting the usual sort of job: a lost camper, probably dehydrated, perhaps turned round after ignoring the map. I had dealt with three of those in the past month. The money was decent and the paperwork straightforward.

The Forestry and Land Scotland district office stood on a corner plot with a gravel car park and a flagpole outside. The building was painted that particular shade of government beige which probably had an official name. I parked my mud-spattered estate car beside a white Land Rover Discovery carrying Forestry and Land Scotland branding, then took my field rucksack from the passenger seat.

Inside, the place smelt of burnt coffee and photocopier toner. There was a service bell on the front desk, but I did not need to use it. A woman in a Forestry and Land Scotland polo shirt was already looking up from her computer.

"Callum Reid?" she asked.

"Yes."

"Fiona Mercer. We spoke on the phone."

She stood and reached across the desk to shake my hand. Her grip was firm and brief.

"I've got the file ready. Would you like coffee first?"

"I'm fine, thanks."

She nodded, turned and took a buff card file from a wire tray behind her. It was thicker than I had expected. She placed it on the desk between us and tapped the tab with one finger.

"This isn't exactly what we discussed," she said.

That should have been my first warning. I opened the file anyway. The top sheet was a standard UK incident form: date, time, an Ordnance Survey grid reference backed up by GPS coordinates, and a brief description.

A couple had made a 999 call from near Loch Quoich after hearing somebody screaming for help. Police Scotland control had relayed the call to the relevant rescue coordinators. When the search team arrived, they found the couple but nobody else. There was no person in distress and no evidence that another party had been in the area.

I turned to the next sheet. A different date and location, but the same account. Emergency call, response, nothing found.

"How many of these are there?" I asked.

"Six in the past two months," Fiona said. "All around the remote lochs and canoe routes of Lochaber. All the same pattern."

I continued through the reports. She was right. Each one ended in the same way. Somebody heard or saw something and reported it. The responders found nothing.

"You think they're connected?"

"I don't know what to think. That's why you're here."

I closed the file and looked at her.

"You said there was a lost camper."

"I said we had a situation requiring someone with your background."

She folded her arms.

"You worked in search and rescue for how long?"

"Seven years."

"And before that you were a constable with Police Scotland."

"Yes."

"Then you've seen false alarms."

"Plenty."

"Six in two months feels like more than coincidence, particularly when the witnesses describe similar things. Voices where nobody should be. Lights moving through the trees. One man said he heard his daughter calling to him, although she was at home in Lincolnshire."

I picked up the file again.

"What do you want me to do?"

"Start with the first couple, Helen and Daniel Pritchard. They're still nearby, camping near the public launching place at Loch Arkaig. They've agreed to speak to you."

She slid a note across the desk. It gave an Ordnance Survey grid reference and the location of their shoreline camp.

"Euan Fraser will meet you there. He's local and knows these waterways better than almost anyone. He'll take you to the place where they heard the voice."

"Fraser," I said. "I know that name."

"He volunteers with Lochaber Mountain Rescue Team and with local water searches. He also submits reports to BUFORA."

I looked up.

"The British UFO Research Association?"

"That's the one."

"You're pairing me with a UFO investigator."

She did not smile, but something shifted around her eyes.

"Euan can be intense, but he knows the area, and he's been tracking these incidents in his own time. He may have context you'll need."

I did not love the arrangement, but I had worked with worse. I slipped the file into my rucksack.

"Anything else I should know?"

"Don't go out alone, and check in every twelve hours. Use the radio where you can and the satellite phone where you can't."

"Standard procedure."

She hesitated.

"Follow it anyway."

I met Euan Fraser an hour later at the public launching place on Loch Arkaig. He was waiting beside a faded blue Toyota Hilux, with two canoes already unloaded on the gravel. He looked younger than I had expected, perhaps in his mid-thirties, with shaggy light-brown hair under a canvas cap and the lean build of someone who spent more time walking hills than sitting down to meals.

"Callum," he called as I pulled in.

"That's me."

He crossed the car park in a few quick strides and offered his hand.

"Euan. Good to meet you. Fiona said you're looking into the calls."

"Starting with the Pritchards."

"Right. Helen and Daniel. I spoke to them the day after they reported it. Got a few details that didn't make the official file."

He took a small notebook from his jacket pocket and opened it.

"They were camped about three miles from here, near a canoe carry leading towards Loch Quoich. It was about 22:30. Helen heard it first. A woman's voice, crying as though she was lost or hurt."

I took out my own notebook.

"Did she give a direction?"

"South-west, across the water."

Euan tapped the page.

"Daniel heard it as well. He said it sounded close, perhaps a hundred metres away, but when he called back, it moved as though it was circling them."

"Moved how?"

"The voice came from one direction, then another. Then it screamed."

I wrote that down.

"Screamed?"

"Not shouted. Screamed as though something had terrified her. That's when they rang 999. The search team found nothing. Not a footprint, not a single piece of equipment. Local access records, outfitter bookings and known camping parties did not put anyone else in that immediate area that night."

Euan closed his notebook and looked at me.

"But this wasn't the only time. Six calls in two months, all around these lochs and canoe routes, all following the same pattern. Somebody hears a voice, reports it, and we find nothing."

"Fiona mentioned that."

"Did she mention the lights?"

I stopped writing.

"What lights?"

"Three reports mention them. Not headtorches or ordinary torches. Lights moving between the trees. One witness said it resembled a hurricane lamp, but it was travelling roughly six metres above the forest floor."

Euan leant against the Hilux.

"I've mapped the locations. They form a cluster within a radius of about twelve miles."

"Could be youngsters playing games. Could be somebody messing about."

"Could be."

He did not sound convinced.

"But six times? In country this remote? And each time it vanishes before anybody can confirm what was there?"

I put my notebook away.

"Let's begin with what we can verify. The Pritchards heard something. We visit the location, examine it and document what we find."

Euan studied me for a moment, then nodded.

"Fair enough. Have you paddled these lochs before?"

"Once, a long time ago."

"The water's easy enough today. We'll canoe to their camp, speak to them and then go to the place where they heard it. It'll take most of the day."

We loaded my equipment into one of the canoes and pushed off shortly before noon. The water was calm, dark and cold-looking. Scots pines crowded both shores, dense enough that I could see only a few metres beyond the tree line. The sky was overcast but did not threaten rain. It was simply grey.

Euan sat in front and set a steady paddling rhythm. I matched it. We spoke little for the first mile. The only sounds were our paddles entering the water and the occasional bird calling from the trees.

Then Euan said, "Do you think I'm mad?"

"I don't know you well enough to think anything."

"But you heard BUFORA and assumed I was some conspiracy obsessive."

I did not answer immediately.

"I understand that you submit reports to them. That's what Fiona told me."

"I do. I've submitted four in the past year. Two were probably drones. One was a weather balloon. I don't know what the fourth was. But I record what I see and send it in. That's all."

"Fair enough."

"I'm not saying this is UFOs," he continued. "I'm saying there's a pattern. People are hearing things that shouldn't be there and seeing things that don't make sense. Nobody takes it seriously because it sounds strange."

"I'm taking it seriously. That's why I'm here."

He glanced back.

"You're here because Fiona is paying you."

"That as well."

He almost smiled, and we carried on paddling.

We found the Pritchards at their camp shortly after 13:00. They had pitched a two-person tent near the shore and lit a small fire within a ring of stones. Helen sat on a log, both hands wrapped around an enamel mug. Daniel rose when he saw us approaching.

"That's Euan," Helen said, squinting towards the canoes. "I don't know the other man."

We beached the canoes and I introduced myself. Daniel shook my hand. Helen remained seated but nodded.

"Fiona Mercer said you'd be willing to take me through what happened," I said.

"We've already told Forestry and Land Scotland and the rescue people," Daniel said.

"I know. I've read the incident form. I'd like to hear it again in your own words."

Helen and Daniel exchanged a look. Then Helen set down her mug and stood.

"It was our second night here," she said. "We'd just finished eating. It was dark, about 22:30, when I heard somebody crying."

"Where?"

She pointed south-west across the loch.

"Over there. It sounded like a woman. She wasn't loud, but she was clear, as though she was lost."

"What did you do?"

"I asked Daniel if he could hear it. He could. We both stood and listened. That's when she called for help."

"What did she say exactly?"

Helen's jaw tightened.

"She said, 'Help me, please.' Twice."

"Did either of you answer?"

"Daniel did. He shouted and asked where she was. That's when it moved."

I looked at him.

"Moved how?"

"The voice came from somewhere else," he said. "First south-west, then west, then north. It was as if she were running in a circle round us."

"How quickly?"

"Too quickly. Faster than anyone could run through those trees in the dark."

Euan was writing in his notebook. I kept my attention on Daniel.

"Then what happened?"

"She screamed," Helen said quietly. "It wasn't like the crying. It was loud. It felt..."

She stopped.

"Felt what?"

"Physical. As though it struck me in the chest."

I wrote that down.

"How long did the scream last?"

"Two seconds, perhaps three. Then nothing."

"No other noises? No footsteps or breaking branches?"

"Nothing," Daniel said. "That's when we rang 999."

I looked at Euan. He was staring across the water towards the place Helen had indicated.

"We're going over there," I said. "Would either of you like to come?"

Helen shook her head at once.

"No."

"We'll remain here," Daniel said.

Euan and I paddled south-west across the loch. The water remained calm, but the air had grown colder. My breath showed in front of me.

"Do you believe them?" Euan asked.

"I believe they heard something."

I did not add that I doubted they had heard what they thought they had.

We reached the opposite shore and dragged the canoe onto a narrow strip of gravel. The woodland was dense there, mostly pine, birch and rowan, with undergrowth thick enough to make every step awkward. I took out my torch although daylight remained. Euan did the same.

"They said the voice came from here first," he said, stepping amongst the trees.

I followed. The ground was soft beneath old needles and moss. I saw no footprints, broken branches or disturbed soil.

We went about fifty metres into the trees, sweeping our torch beams over the ground.

"Nothing," I said.

"Not yet."

We continued. The trees thinned slightly and the ground rose. That was when I saw it: a light moving amongst the trunks, perhaps a hundred metres ahead.

I stopped.

"Can you see that?"

Euan turned.

"Yes."

It resembled the warm yellow light of a hurricane lamp, steady but swinging gently as it travelled from left to right. It was not moving quickly, only at walking pace, but it hung roughly six metres above the forest floor.

"Hello!" Euan shouted.

The light continued moving. I started towards it, and Euan followed. We forced our way through the undergrowth, boots snapping dead wood while our torches cut through the dimness. The lamp-like glow maintained the same speed. It neither hurried nor stopped.

"Hello!" I called. "Forestry and Land Scotland!"

There was no answer.

We narrowed the distance to fifty metres, then thirty. The light passed behind a dense stand of birch, and I lost it for a second. By the time I cleared the trees, it had gone.

I stopped and swept my torch in a full circle. There was nothing.

Euan reached me, breathing heavily.

"Where did it go?"

"I don't know."

We stood in the silence. No footsteps, no voices. Only wind stirring the branches and the faint sound of water behind us. I examined the ground. There were no tracks or signs that anyone had been there.

Euan looked at me.

"Do you still think this is nothing?"

I did not answer. I kept moving the beam between the trees, searching for something I could not find.

Helen kept returning to the way the voice had travelled. We were back at the Pritchards' camp, sitting in folding chairs Daniel had taken from the tent. The fire had burnt down to glowing coals.

"It wasn't merely moving," she said. "It moved wrongly."

Daniel stood beside a rowan near the tent, arms folded.

"It was as though it came through the water, not around it."

"Through it," I said.

I recorded the wording in my field notebook. Euan crouched at the shoreline, studying the opposite bank through binoculars from his rucksack.

Helen watched me.

"You don't believe us."

"I'm writing down what you're telling me."

"But you don't believe it."

I kept my tone level.

"I'm not here to decide what happened. I'm here to document your account and inspect the area."

She did not look satisfied. Daniel shifted his weight and continued watching me.

Euan rose, returned to us and let the binoculars hang around his neck.

"Did the voice seem to come from different heights?" he asked. "Higher at one point, then lower?"

Helen frowned as she considered it.

"Perhaps. I don't know. Near the end it seemed to be everywhere at once."

"Before the scream?"

"Yes. Before that."

Euan drew out his small notebook and turned through several pages.

"Two other reports mention that. The voice seemed to come from several directions at once."

"It could have been an echo," I said. "Sound bouncing between water, slopes and trees. The ground may have channelled it oddly. People don't judge acoustics well when they're frightened and it's dark. The mind fills gaps."

Or it could have been a prank: somebody with a loudspeaker in a boat, drifting about and frightening campers. It would not have been the first time I had encountered people who found it amusing to terrify strangers in isolated country.

Euan treated it differently. He used phrases such as "lure tactic" and "bait behaviour", describing it as one might describe a predator drawing its prey. I did not accept that. If somebody were trying to lure campers from safe routes, we should have found bodies by then, or at least signs of a struggle.

We had six reports and no evidence of contact. That was what I kept coming back to: six incidents, no victims, only frightened people, strange voices and moving lights.

Daniel spoke again.

"We're not making this up."

"I didn't say you were."

"But you think we heard an echo or something."

I met his eyes.

"Sound behaves strangely over water at night, particularly in this terrain."

He stared at me for a moment, then looked away.

Euan asked several more questions about timing and distance, recording Helen's answers. She kept glancing at me, probably trying to decide whether I thought she was mad.

I did not. I simply believed there was a rational explanation we had not yet found.

We finished about twenty minutes later. I gave them the number for my satellite phone in case they heard anything else, and Euan handed them a card bearing his personal mobile number.

We paddled back to the launching place in silence. Euan did not press his theories on me, which I appreciated. The entire exercise felt like a waste of time until my radio crackled as we were fastening the canoes to his Hilux.

It was Morag Sinclair, one of the Forestry and Land Scotland staff working with the southern search sector. Her voice was clipped and direct.

"Control, this is Sinclair. I've found a canoe at the eastern canoe landing place on Loch Garry. It's overturned and trapped beneath a fallen tree. There's fresh blood on the gunwale. Requesting additional search teams and water-rescue resources."

That changed matters. Euan looked at me. I was already reaching for the radio.

"Sinclair, this is Reid. What's your location?"

She gave me an Ordnance Survey grid reference.

"Eastern landing place on Loch Garry, about four miles from your last check-in."

"Understood. We're on our way."

I did not wait for Euan to finish securing the second canoe. I began pulling our equipment free and carrying it towards the water. Blood meant an injury, a real one rather than a disembodied voice or a wandering light. Somebody might be hurt, in the water or on shore.

That was something I understood. Something concrete.

Euan caught up with his rucksack and a coil of rope.

"Do you think it's connected?"

"I don't know yet."

We relaunched one canoe and paddled hard. It took about forty minutes to reach Loch Garry and another ten to find the landing place. Morag stood near the shore beside an overturned aluminium canoe pinned beneath a moss-covered fallen trunk. The stern remained in the water while the bow projected upwards, jammed fast.

I pulled our canoe onto the gravel and went over. Morag nodded but did not waste time on greetings.

"Found it thirty minutes ago," she said. "Blood's on the starboard gunwale near the centre thwart. Still tacky."

I crouched beside the canoe. A roughly ten-centimetre smear marked the aluminium edge. It was dark red and fresh enough not to have dried completely.

"Any sign of the occupants?"

"Not yet. I called it through before carrying out a full perimeter search. I wanted another pair here first."

"Sensible."

You did not search alone when an injured, frightened or disorientated person might be nearby. Euan was already circling the landing place, examining the ground with his torch. I stood and studied the tree line. A canoe carry led east from the shore through dense pines. Water lapped quietly against the bank.

"We're starting a grid search," Morag said. "Alison is coordinating from the main landing. The briefing is in thirty minutes."

Alison Grant was the Forestry and Land Scotland area manager overseeing the land-management staff and volunteers. I had worked with her during a recovery operation two years earlier. She was capable, exacting and strict about procedure. Police Scotland would control any criminal investigation, but until there was clear evidence of one, Alison had authority over my participation in the organised search.

"Understood," I said.

Morag went to place marker tape near the canoe without touching it. Euan returned, frowning.

"No tracks. The ground is soft enough that we'd see them if anyone had walked away."

I studied the mud beside the water. He was right. There were no boot prints and no drag marks.

"Perhaps they went into the water."

"Perhaps."

We followed the canoe carry to the main landing, where a staging area was already taking shape. Two Forestry and Land Scotland staff were setting up a folding table with maps and radios. Several Lochaber Mountain Rescue Team volunteers and trained local water-search volunteers waited nearby for instructions.

Alison arrived ten minutes later in a Forestry and Land Scotland vehicle, carrying a clipboard and a weatherproof equipment case. She was in her mid-forties, her greying hair drawn into a tight knot, and wore field uniform beneath her waterproofs. She saw me and came across.

"Reid."

"Grant."

"You're the civilian specialist Fiona engaged for the voice reports."

"Yes."

She glanced at Euan, then back at me.

"This is a separate search and possible recovery. I need you concentrating on the assigned grid, not chasing theories."

I nodded.

"Understood."

She did not appear convinced.

"I mean it. We may have an injured casualty, the water is cold and the light is failing. You have no police powers, and I don't need anyone leaving their sector to pursue speculation."

"I'm here to help find whoever was in that canoe."

"Good."

She returned to the table and began the briefing. It covered the search radius, radio schedules, sector boundaries and safety procedure. She assigned pairs and sectors. Euan and I remained together, which made sense because we already had a canoe afloat.

The operation was professional and efficient. Alison ran it tightly, leaving no room for speculation or irrelevant questions. I tried to ask whether there had been earlier incidents in the area. She stopped me at once.

"We're dealing with this search," she said, "not historical reports."

"I'm trying to establish whether there's a pattern."

"There is no established pattern. What we have here is weather, cold water and poor judgement, as with most capsized canoes recovered from these lochs."

Euan opened his mouth, probably to mention the six reports of voices, but I caught his eye and gave a slight shake of my head. He closed it again.

Alison treated me as she would any civilian consultant: courteously but at a distance. I was there to perform a defined task, not exercise police authority or conduct an independent criminal inquiry. She made that clear without labouring the point.

After the briefing, the teams dispersed. Euan and I were returning to the canoe when he leant closer.

"She isn't telling you everything," he said quietly.

"What do you mean?"

"The missing-person reports. I've been checking records in Fort William and speaking to outfitters. There are far more names than the six voice-and-light incidents."

I stopped.

"How many?"

"Fifteen in the past two years. Perhaps twenty. Some were recorded as accidents: capsized boats, falls, exposure. Others remain open missing-person cases."

"That isn't necessarily unusual here. Lochaber draws plenty of visitors, and people make mistakes."

"Yes, but the rate has risen, and many of them are never found. Not even their bodies."

I looked at him.

"Are you suggesting somebody is concealing it?"

"I'm saying the information keeps expanding even after incidents are treated as closed, and nobody wants to discuss it."

I did not know what to make of that. Alison was not the sort to bury evidence. If she recognised a genuine pattern, she would take it to Police Scotland and the rescue coordinators. Perhaps she simply saw what she had described: bad weather, cold water and bad decisions.

Euan watched me, waiting.

"Let's find whoever was in that canoe," I said. "Then we'll consider the rest."

He was not satisfied, but he nodded.

We returned to the water. Our next sector included the canoe carry near the Pritchards' camp. Alison had sent us there with a map and an exact grid reference.

I expected churned mud and obvious boot marks, perhaps trampled vegetation if anybody had truly run through the woodland in the manner Helen described. Instead, the path looked combed. It was the only word that fitted.

Sections of earth that should have been broken and irregular had been smoothed. Leaves lay too evenly to have fallen or blown that way. They appeared to have been placed.

About thirty metres along the carry, I stopped and crouched. Euan came up behind me, equipment rattling in his rucksack.

"What is it?"

I pointed to a puddle beside the path. Somebody had laid spruce needles across it in a straight line at perfectly regular intervals. The needles were fresh, with green still showing at their bases.

"Could be an attempt at drainage," Euan said.

"Drainage doesn't arrange individual needles."

I rose and continued, examining the ground. Another puddle, about three metres farther on, had needles laid across it in the same pattern and at the same spacing.

It was unnatural, and that unsettled me. Euan photographed it with his mobile. I did not stop him. It was not proof of anything specific, but it deserved to be recorded.

I studied the margins for prints or drag marks. The soil was soft enough to hold clear boot impressions, particularly from somebody moving quickly. Instead, it looked as if it had been reset. Not completely erased, but deliberately smoothed and adjusted.

"Callum."

I turned. Euan was pointing to a rowan about five metres from the path. A strip of orange reflective tape had been tied around a branch roughly two and a half metres above the ground. Its edges were clean and bright.

I went over and looked up. Guides sometimes used such tape to mark routes visible by torchlight from a distance.

"An old route marker?" Euan said.

"Perhaps."

I entered the grid reference and a description in my notebook. The tape showed no fading or weather damage. It appeared new, or at least recent.

Morag approached along the carry with a handheld GPS receiver. She looked at the rowan, then at me.

"Found something?"

"Reflective tape. High up and clean."

She shrugged.

"People mark routes. It may simply be rubbish left behind."

"It was positioned deliberately," I said. "High enough to be visible from a distance and recent enough that the edges haven't weathered."

Morag regarded me for a moment, then looked back at the tape.

"Do you want it entered in the search log?"

"I've already recorded and photographed it. It should stay in place for now."

She nodded and continued along the path. Euan waited until she was beyond hearing, then stepped closer.

"Do you think someone is marking a network of paths?"

"I think somebody is doing something. I don't know what yet."

We moved on. The carry twisted through dense pine woodland before opening beside a narrow bay absent from the main map. The water was motionless and dark green near the shore. There was no wind.

Euan saw the objects first. He stopped and pointed to a clearing about twenty metres from the water. Camping equipment lay scattered across it.

We went closer. Food had been dumped on the moss: cereal bars still in their wrappers, a half-empty bag of fruit-and-nut mix and an apple with one bite missing. A torn buoyancy aid lay crumpled beside a flat rock. Foam protruded through a neat rip along one shoulder strap.

An unused billycan stood beside a log, cold cooking oil pooled inside it.

For a moment, I felt relieved. Abandoned equipment could be logged and traced, perhaps leading us to whoever had occupied the canoe. People often discarded things when frightened or in a hurry.

I crouched and examined the billycan without disturbing its position. The oil was thick and cold. There was no soot, scorching or heat discolouration on the metal.

"It hasn't been used for cooking," I said.

"What?"

"There's no char or residue. Somebody poured cold cooking oil into a clean billycan and left it here."

Euan bent closer.

"Why would anyone do that?"

I did not answer. I was already assessing the rest of the clearing.

Animals had not torn into the scattered food. The damage to the buoyancy aid looked too clean and deliberate. The whole scene felt staged.

I recorded the grid reference, every object and its condition. I did not include my suspicion as a conclusion because I could not yet prove it.

Euan walked towards the tree line, then stopped.

"Callum."

I joined him. He was examining a rowan on the edge of the clearing. Its trunk bore three linked oval cuts arranged vertically, each roughly five centimetres across. The shallow wounds were fresh, with sap still tacky at the edges. The blade had broken the bark and scored the wood beneath without cutting deeply.

"Done with a knife?" Euan asked.

"Yes. Crude, but deliberate."

I sketched the pattern in my notebook while Euan photographed it from several angles. The linked ovals meant nothing to me. They might have marked time, indicated a route or been nothing more than casual vandalism. But they were recent enough that the bark had not begun to close.

I logged them as deliberate knife cuts and moved on.

Darkness came faster than I expected. One moment we appeared to have nearly an hour of grey daylight remaining. The next, fog rolled over the water and reduced visibility to less than six metres.

Euan wanted to use our headtorches. I told him not to.

"We need to see," he said.

"Switch yours on and you'll understand."

He did. The beam struck the fog and reflected straight back into his eyes. He swore and turned it off.

"Exactly," I said.

This was not thin mist likely to burn away by morning. It was dense and low, resting on the loch and pushing between the trees. It smelt of wet moss and cold stone. I could hear water touching the shore three metres away but could not see it.

Our canoe was a dark shape pulled halfway onto the gravel. The rucksacks were shadows beside it. Euan sat on a flat rock and tightened his jacket around himself.

"How long do we wait?"

"Until it clears or morning arrives, whichever comes first."

"Wonderful."

I did not relish it either. We had spent the hours since the briefing covering our assigned sector and recording positions, without finding a casualty. The staged camp remained in my thoughts: cold oil in an unused billycan, the unnaturally torn buoyancy aid, the linked cuts in the rowan. Somebody had been doing something out there. I simply did not yet know what.

Euan took out his notebook and began turning pages under the small beam of a key-ring torch. It was dim enough not to flare against the fog. He muttered about triangulation and clusters of incidents.

I stopped listening when I heard the sound.

It was low and wet, almost like crying but muffled, as though it travelled through water rather than air.

I stood.

"Can you hear that?"

Euan stopped in the middle of a sentence and tilted his head.

"Yes."

The noise came from somewhere on the loch, perhaps fifty metres out. It rose and fell in a rhythm that felt wrong: too slow and too deliberate.

Euan went to the water's edge, his boots grinding on the gravel.

"Someone's out there."

"Possibly."

"We should paddle out, take a bearing and triangulate the source."

I shook my head.

"No."

"Callum, if somebody's in the water-"

"We're not launching into fog this thick. We can't see the shore or any obstruction. If we capsize, we'll be the ones requiring rescue."

Euan turned towards me. I could barely distinguish his face in the darkness.

"So we simply listen?"

"For now."

The noise continued. It neither approached nor moved away. It remained in the fog, rising and falling like slow breathing.

Euan paced along the shore. I stayed near the canoe and listened. The crying lasted perhaps three minutes, then stopped without warning. It did not fade or end in a final whimper. One instant it was there; the next it was gone.

Euan stopped pacing.

"What the hell was that?"

I did not answer. I was listening for movement, splashing or anything that might reveal where the sound had come from or what had produced it.

There was nothing.

Then a scream tore through the air behind us. It was sharp and close, perhaps thirty metres along the canoe carry.

Euan spun round.

"Christ."

I was already moving. I snatched my torch from my rucksack and ran towards the path. Its beam cut a narrow tunnel through the fog, just enough to keep me from tripping over roots. My boots struck the earth as I pushed on, searching left and right.

"Callum, wait!"

Euan's voice came from behind me, followed by his footsteps crashing through the undergrowth.

I did not wait. If somebody was hurt, if they had fallen or been attacked, I needed to reach them immediately.

I ran about forty metres. The beam passed over trees, stones and the carefully smoothed soil we had documented earlier.

There was nobody there. No body on the ground, no injured person staggering between the trees and no discarded equipment.

I stopped and turned slowly, holding the torch away from my body.

"Is anyone there?"

No answer.

Euan caught up, breathing hard. He now held his own smaller torch.

"Where are they?"

"I don't know."

Our beams crossed in the fog. The path was visible well enough, and its soil had not been disturbed. There were no fresh prints, drag marks or broken branches.

"Somebody screamed," Euan said. "It came from here. We both heard it."

"I know."

"Then where are they?"

I had no answer.

I searched another twenty metres along the carry, checking both sides, while Euan went back in the opposite direction. We met at the same point five minutes later, having found nothing.

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

I agreed but did not say so. I turned and walked back towards the shore. My chest felt tight. The scream had been close and real. It had not sounded like an echo or a bird.

I saw the change as soon as we reached the canoe. One of our rucksacks had been moved. I had left all three together beside the bow. Mine, with its green straps, now stood about two metres nearer the trees. It had not been thrown or dragged. Somebody had placed it there neatly.

I stopped. Euan almost walked into me.

"What?"

I pointed. He looked at the rucksack, then at me.

"Did you move that?"

"No."

"Are you certain?"

"I'm certain."

Euan approached and crouched beside it. He did not touch it.

"It's yours. The one with the green straps."

"I know."

He stood and swept his torch across the tree line.

"Somebody was here."

That affected me more than the scream or the crying from the loch. Somebody had stood beside our canoe, close enough to handle our equipment, while we ran along the path after a sound that led nowhere.

"They wanted us away from the canoe," I said.

Euan looked at me.

"What?"

"The scream drew us off. It gave them time to come close."

"Just to move a rucksack?"

"To show us they could."

His face tightened. He turned towards the woodland and raised his voice.

"Is anybody there?"

There was no reply. Only fog, darkness and water lapping against the shore.

I went to the rucksack and checked it carefully. The radio, notebook and first-aid kit were still inside. Nothing appeared to be missing. Whoever had handled it had taken nothing. They had merely moved it and set it down.

Controlled. Deliberate.

Euan kept his torch trained on the trees.

"We should report this."

"And say what? That somebody moved my rucksack by two metres?"

"Somebody was watching us, Callum. They were close."

"I know."

But I did not reach for the radio. Alison had already stopped my questions once that day. Without something more concrete, she would treat this as an unverified disturbance rather than evidence of a threat.

I sat on the rock Euan had occupied earlier and pulled my jacket tighter. Fog pressed in from every side. I could no longer see the water or the canoe carry, only our small patch of gravel, the canoe and the rucksacks.

"We're staying here until morning," I said.

Euan did not argue. He sat beside me with his torch resting across his lap, its beam aimed towards the trees.

We did not sleep. I do not think either of us wanted to.

Morning came slowly. The fog did not lift. It merely grew lighter, grey instead of black.

By the time the sun was properly up, we could see perhaps 15 metres. I stood and stretched. My back ached from sitting on the rock all night. Euan looked worse. His eyes were red, and his hair stuck out at odd angles beneath his cap.

"Coffee?" he asked.

"Yeah."

We boiled water on Euan's camping stove and made instant coffee in enamel mugs. It tasted like earth, but it was hot and woke me a little. We were finishing it when I heard boots on gravel.

I turned. A man was approaching from the canoe carry. He was tall, perhaps fifty, with greying brown hair beneath a worn cap. He wore a guide's layered outdoor clothing and stained boots, with a rucksack slung over one shoulder.

He raised a hand in a half-wave. "Morning."

I stood. "Morning."

He came closer and stopped about 3 metres away. He had pale eyes, a weathered face and a pronounced nose. There was a small scar across one knuckle.

"You two with the search?"

"Yes," I said. "You?"

"Graham Sutherland. I guide out of Fort William. Lochaber Outdoor Expeditions sent me to check the southern sectors."

Euan stood and brushed dirt from his trousers. "You've been out here all night?"

"Yeah."

Graham looked at the canoe, then at our rucksacks, then back at me. "Rough night for it. Fog came in thick."

"It did."

He shifted his weight and adjusted the strap on his rucksack. "Find anything?"

"An overturned canoe yesterday. Roughly 10 centimetres of blood on the gunwale. Did you hear about that?"

"I heard." Graham nodded slowly. "Alison radioed it through. Said you were working a search grid."

"That's right."

Graham looked out over the water, although there was little to see through the fog. "Plenty of people capsize canoes out here. Cold water, bad judgement. Happens every season."

I said nothing.

Euan stepped forwards. "Have you been guiding in this area long?"

"Fifteen years."

"Ever seen lights among the trees? A warm light, like a hurricane lamp, moving about 6 metres above the ground?"

Graham's expression did not change. "Lights?"

"Moving horizontally. Higher than anyone could carry one."

Graham shrugged. "Head torches do strange things in fog. Reflections off the water. I've seen that."

"What about on clear nights?" Euan took out his notebook. "Three reports specifically mention lights. All in this area."

Graham looked at the notebook, then at Euan. "You're tracking incidents?"

"I am."

"Huh." Graham adjusted his rucksack again. "Can't say I've seen anything like that. Mostly I see divers and city paddlers who can't read a map."

Euan did not write anything down. "Divers don't travel in straight lines 6 metres above the forest floor."

"No?" Graham said. "But they make noises that'll convince you someone's dying out there, especially at night. Ever heard one close by?"

"I have."

"Then you know." Graham looked at me. "Are you heading back to the search base soon?"

"Probably. Why?"

"Weather's turning. Radio says rain by midday. You don't want to be caught out in it."

I glanced at the sky. It was still grey and shrouded in fog, but he might have been right.

Graham nodded once. "Well, good luck with the search. Hope you find whoever was in that canoe."

"Yeah," I said.

He turned and walked back towards the canoe carry.

He did not offer to help. He did not ask whether we needed anything. He simply left.

Euan watched him disappear. "That man knows something."

"Maybe."

"He shut down every question I asked."

"He did."

Euan looked at his notebook and then at the path where Graham had vanished into the fog. "Do you believe him? About the divers?"

"No."

I walked to the mouth of the path and crouched. The soil was still damp from the fog, and Graham's boot prints showed clearly. Deep tread. Fresh edges. They led from the canoe carry to our camp and then back the way he had come.

His prints crossed the section we had documented the previous day, the section someone had combed smooth and reset. They cut directly through the orderly surface and the pine needles arranged too neatly across the puddle.

I took out my torch and cast its beam low over the ground. The tread marks were deep and sharply defined, the sort left by someone walking with purpose. They were the sort that should have been there when we first examined the route, if people had been using it normally.

Euan came up behind me. "What is it?"

I pointed. He studied the impressions, the smoothed ground beneath them and the trail ahead.

"Those are fresh."

"Yes. The tread matches Graham's boots. Deep lugs with a chevron pattern, same spacing. I saw them when he was standing by the canoe."

Euan crouched beside me. "What does that mean?"

"Someone smoothed this path after the search teams passed through and after people had stopped using it. We documented it before Graham walked across it."

"You think he's the one staging everything?"

"I don't know. The prints don't prove he reset the path. But somebody is maintaining these routes, and Graham is using them."

I wrote down the time, the Ordnance Survey grid reference and what we had found, then photographed the prints and the broken surface. When I had finished, I stood and looked along the route Graham had taken. The fog had already swallowed him.

"We should call it in," Euan said.

I already had the radio in my hand. Morag answered on the second call.

"Sinclair."

"Morag, it's Callum Reid. We've found fresh footprints crossing a section of path that was tampered with. The prints were made after the surface was cleaned."

There was a pause. "Cleaned?"

"Someone smoothed the soil and deliberately arranged the debris. We documented it yesterday."

"I remember." Another pause followed. "You're saying someone is actively maintaining sections of the route?"

"That's how it appears."

I heard paper moving at her end, perhaps a map being opened.

Her voice returned, quieter. "Can you give me a time frame?"

"The prints are fresh. Within the past few hours."

"Can you identify who made them?"

I hesitated. Accusing an experienced local guide on the strength of boot prints alone was not something I intended to do, but I was not going to conceal the match.

"The tread pattern matches Graham Sutherland's boots. He came through our camp this morning."

Static filled the channel. Then Morag said, "Hold there."

The radio remained open. I could hear movement in the background, voices and someone speaking in low tones, though I could not distinguish any words. Euan leaned closer.

Beneath the static, I caught a man's voice. Rural, curt, with a cadence that sounded like Graham's.

I looked at Euan. He had heard it as well.

Morag came back. "Callum, I'm passing this to Alison. She'll want exact details, grid references, photographs and anything else you've logged."

"I've documented it."

"Good. Send everything once you're back within data coverage." She paused. "Do you need police support?"

"I think we do."

More static followed, then a different voice came over the radio. Formal and even.

"Callum, this is Alison Grant. What evidence do you actually have?"

I kept my tone level. "Fresh boot prints over a deliberately cleaned section of path. Reflective markers positioned at eye level. A staged camp. Someone is operating here with intent."

"Intent to do what?"

"I don't know yet."

"Then there aren't reasonable grounds at present for Police Scotland to escalate its response on that basis alone. Document what you find and remain within your assigned search area. We'll review it with the police search coordinator after the recovery operation."

I wanted to challenge her, but I knew it would lead nowhere. "Understood."

"And, Callum, you're here as a civilian search consultant. You have no police powers. If you encounter anyone in the field, you observe, document and report. Nothing more."

"Understood."

The channel closed.

Euan looked at me. "She's shutting us down."

"She's managing risk." I clipped the radio back onto my belt. "And she isn't entirely wrong. We don't have enough."

"We have prints. We have evidence of tampering."

"We have observations. That's all."

I started walking. Euan caught up, the contents of his rucksack rattling softly.

"You heard him on Morag's radio, didn't you?"

I had, but I did not say so. It might have been Graham. It might have been another local guide speaking to the search staff. Or exhaustion might have made the resemblance seem stronger than it was.

I doubted that last possibility, but a faint voice under radio static was not proof.

We continued with the search. Alison's grid covered another 2 miles of shoreline and a small group of islands near the south-eastern end of Loch Garry. Euan checked the GPS coordinates against the Ordnance Survey mapping every few minutes and adjusted our heading.

The island came into view around midday. It was small, perhaps half an acre, covered mainly in rowan, birch and low scrub, with a strip of gravel along its northern side.

Euan took out his notebook and turned through several pages.

"This matches."

"Matches what?"

"The last mobile-phone location linked to Sophie Bennett." He tapped the page. "University student. Reported missing six weeks ago. Her phone registered here once and then went dead."

I pulled the canoe onto the gravel and stepped out.

The island was quiet. There were no birds and no wind, only water lapping against the stones.

We searched the perimeter first, following a standard pattern. Euan went left and I went right. We met on the far side ten minutes later, having found nothing. No tent, no equipment and no tracks.

Euan pointed towards the centre. "Thicket."

I had seen it. Dense young trees and tangled scrub formed a patch perhaps 6 metres across. It was the sort of place most people avoided because walking around it was easier than forcing a way through.

We pushed into it. Branches scraped my jacket. Euan's rucksack caught twice, and he had to wrench it free.

Then I saw blue fabric.

It was a tarpaulin, faded but intact, pinned at each corner by smooth stones and pulled tight over a dry hollow between two low rocks.

I stopped. Euan came alongside me and went still.

The tarpaulin was clean. There was no mould or rot, and no drift of leaves across it. Someone had placed it there recently or had been maintaining it.

Before touching anything, I photographed it from several angles and recorded the grid reference. Then I crouched and lifted one corner.

Equipment had been arranged beneath it in neat rows: a waterproof dry bag, two coils of cord, a metal water bottle, a head torch with fresh batteries visible through its casing, a smaller tarpaulin folded into a square and a first-aid kit still sealed in plastic.

Euan knelt beside me. "A supply cache."

That was exactly what it was. Not abandoned camping equipment and not rubbish. It was organised, intentional and ready to use.

I photographed the layout before picking up the dry bag. Inside it was a notebook sealed in a transparent plastic pouch. I photographed its position, removed it and examined the seal. The pouch had been heat-sealed along the top.

I tore it open and took out the notebook. It was small, perhaps 13 by 18 centimetres, with a black cover and spiral binding.

The pages contained dates, initials, locations and short entries.

12 June. AR. Returned North Morar. Quiet.

18 June. KN. Waters calm. No contact.

2 July. SB. Loch Garry. Responsive.

I stopped at that entry. SB. Sophie Bennett.

Euan leaned over my shoulder. "What is that?"

"A log."

I continued reading. There were different initials and dates throughout, but every entry was brief and clinical. Some said "Returned". Others said "No contact", "Responsive" or "Cooperative".

They did not read like notes made by someone trying to survive in the hills. They read like reports.

Euan pointed to the entry for 2 July. "That's her. That's Sophie."

I thought so too. The date fitted the period of her disappearance, and the location matched the last signal from her mobile.

I turned to the back. The final page had been pressed flat. A dark brown organic stain had dried into the paper. Fixed to it was a clump of long, dark-blonde hair.

Euan reached towards it, then stopped himself.

"Is that...?"

"Could be blood," I said. "Could be something else. Don't touch it."

The stain had dried and flaked at the edges. I closed the notebook and placed it carefully on the tarpaulin beside the other equipment.

Euan spoke quietly. "This wasn't left by somebody lost in the woods."

"No."

"It's organised."

"Yes."

I looked over the coils of cord, sealed first-aid kit and spare batteries. Nothing was random. Nothing had simply been abandoned. This was part of an operation.

Euan stood abruptly. "We need to report it now."

I agreed, but our radio coverage was poor on the island. I also knew what Alison would say if we reached her. Photograph it, record it, leave everything in place and wait for Police Scotland to process the scene. She would tell us not to disturb anything further and to remain within our search grid.

She would be right about the evidential risk. I was a civilian now, not a constable, and I had already opened the sealed pouch. Removing the notebook could complicate its handling in court.

But whoever maintained the cache knew these routes better than the search teams did. If we left it there while trying to establish contact, it might disappear.

I photographed the notebook in relation to the rest of the cache once more, then put it inside a clean evidence bag from my search kit, sealed it and wrote the time and grid reference across the label. I slipped it into an inner pocket of my jacket.

"What are you doing?" Euan asked.

"Taking it with us."

"Callum..."

"If we leave it, it may be gone before the police arrive. I've photographed its position and documented everything I've done. I'll account for the decision in my statement."

I stood and began moving back through the thicket. "We're leaving. Now."

Euan did not argue. He followed quickly.

At the gravel strip, I pushed the canoe into the water. Euan climbed in, still looking back towards the island. I shoved us clear and began paddling.

That was when the fog arrived.

It did not build slowly or drift towards us in ragged patches. It came across the loch as a wall, low and dense, travelling faster than the wind could have driven it. One moment I could see the far shore. The next, I could not see beyond the bow.

Euan twisted round in the front seat. "Callum."

"I see it."

The air turned cold. I felt the damp settle across my face.

The fog swallowed the island behind us, then the water to either side, until only the few feet immediately surrounding the canoe remained visible.

I kept paddling. Same heading, straight back across the channel. Euan checked the GPS.

"We're drifting south."

I corrected our course. The fog seemed to press closer.

Somewhere behind us, perhaps on the island or perhaps much nearer, I heard a sound. It was low and wet, the same crying we had heard the night before.

Euan heard it too. He did not turn. He kept watching the GPS.

I paddled faster.

We were halfway across when the fog seemed to slam shut around us, as if someone had dragged a curtain over the water. Visibility fell from perhaps 100 metres to 3 metres in the span of a single paddle stroke.

Euan stopped midway through his stroke. Water dripped from his raised paddle into the loch.

I continued. Same bearing, same rhythm. The GPS clipped to his rucksack strap showed our direction, and I could hold a line without visual reference if necessary.

Then I noticed my compass.

I kept a small backup compass attached to my jacket zip, an old habit from seven years in mountain rescue. Its needle was not spinning. It was twitching, as though something pulled it one way and released it in rapid bursts.

North to north-east. Back to north. Then north-west. Back and forth.

I stopped paddling.

Euan noticed. "What?"

I watched the needle jump.

He turned far enough to see what I was staring at. "What is it?"

"The compass is wrong."

He took his own from his jacket pocket and held it flat on his palm. Its needle behaved in exactly the same way, twitching between inconsistent headings.

"Magnetic interference," Euan said. His voice was tight. "Mineral deposits beneath the loch can sometimes do that."

"Yeah."

I did not believe him. Neither did he.

The crying began again. It was the same low, wet, unnatural sound, seeming to travel through the water rather than over it.

This time it did not remain formless. It changed into words.

A woman was calling for a child. She was not screaming. It was the careful, controlled call of a parent who had lost a child in a supermarket and was trying not to let the panic enter her voice.

"Jamie."

"Jamie, where are you?"

Euan became completely still. He did not turn his head or move his hands. His paddle lay across his lap, and his shoulders were locked.

The voice came from our left, perhaps 30 metres away, perhaps closer. The fog made distance impossible to judge.

"Jamie, please answer me."

I resumed paddling, holding the same heading.

Euan whispered, "Do you hear that?"

"Yes."

"We should..."

"No."

The canoe drifted.

I felt it change beneath us. We were no longer holding our course. There was no current in that channel and no wind strong enough to move us, but something was drawing the canoe left, towards the voice.

I drove my paddle deep and corrected. The canoe swung back towards our bearing, yet the pull continued. I had to paddle hard against it.

Euan finally looked left into the fog.

His face went slack.

"Don't," I said.

He did not answer.

I looked.

Something pale stood within the fog, brighter than the grey surrounding it. It was rising from the water about 20 metres away. Not surfacing. Rising, as if it had been standing on the loch bed and was simply unfolding towards us.

I saw the hair first. Long, dark and wet, hanging in thick strands tangled with weed. It moved wrongly, not flowing with the water but dragging through the air.

Then I saw its face.

It appeared improperly drawn across the skull beneath it. The skin was stretched over bones that did not fit. Its eyes sat too far apart, and its mouth was open, though not nearly wide enough to make the sound that came from it.

"Jamie."

The figure slid sideways. It did not walk or swim. It travelled horizontally across the surface without making a ripple.

Then it vanished.

The fog opened at once, like a door flung wide. The shore lay about 50 metres ahead, with the dark line of trees and the gravel landing place where we had launched that morning.

I paddled as hard as I could. Euan did not move, so I paddled for both of us. We reached the shore in less than a minute.

The canoe scraped over gravel. I was out before it stopped. I seized the bow and hauled it clear of the water.

Euan climbed out slowly. His face was grey and his hands were shaking. He sat on a rock and bent forwards with his head between his knees.

I said nothing. I unloaded our rucksacks and placed them on the gravel. Then I walked 3 metres along the shore and stared across the water.

The fog had gone completely. The loch was calm beneath an overcast but clear sky. There was no wind and no sound except water moving against the stones.

At last, Euan spoke. "What was that?"

"I don't know."

"You saw it."

"Yes."

"Its face..."

"I know."

He stood and came towards me. His hands were still trembling. "We need to report this."

"Report what?"

He stared at me. "What we just saw."

"And what exactly do we say?"

He opened his mouth, closed it, then tried again. "I don't know. That there's something in the water. That people aren't only disappearing because they're lost. That..."

"We report facts," I said. "Fog reduced our visibility. We heard a voice. We experienced an unexplained drift and compass interference. We reached the shore. That's what goes into the field log."

"That isn't enough."

"It's what we can support."

He did not argue. He stood breathing hard and watching the loch as though it might open again.

I checked my watch. It was 16:30. We had been on the water for six hours.

"We're heading back," I said.

Euan nodded.

We did not speak while loading the canoe or as we paddled towards the main search base. Euan checked the GPS every two minutes. I held us to our course. Both of us pretended the compass needles were not still twitching.

Graham appeared that evening.

We had stopped at a small canoe landing place about a mile from the search base so that we could eat and try the radio again. The sun was sinking and the light was failing. Euan was searching his rucksack for a cereal bar when I heard boots on gravel.

Graham emerged from the trees as though he had been waiting there. He wore the same battered cap and layered jacket. His pale eyes did not blink often enough.

He raised a hand in a half-wave. "Reid. Fraser."

I stood. Euan stopped searching and turned.

Graham halted about 5 metres away, close enough for conversation but far enough that I would have to cover ground to reach him.

"Alison Grant sent me," he said. "There's a shorter canoe carry from here. It'll get you back to the search base before dark."

I did not move. "We know the route."

"This one is quicker."

"We're fine."

Graham tilted his head. "She said you'd probably object. Told me to say it wasn't a suggestion."

Euan looked at me. I did not return the glance.

"Why send you?" I asked.

"I know the area."

"So do we."

Graham shrugged. "I'm only passing on what I was told. If you want another two hours of paddling in the dark, that's your decision. The carry I'm offering will cut the journey in half."

I did not believe him. I did not believe Alison had sent him, and I did not believe he had happened upon our position by chance.

Radio coverage at the landing was too poor to verify his claim. Every attempt produced only broken static.

He already knew where we were. Refusing to follow would not make him forget.

"Lead on," I said.

Graham nodded and turned towards the trees.

Euan caught my arm. "Are you serious?"

"He has already found us."

"Then we call it in."

"We've tried. And what do we report if we do get through? That we distrust the guide Alison supposedly sent?"

Euan released me, though he looked far from convinced.

We followed Graham into the trees.

The light deteriorated quickly. Shadows gathered beneath the pines, and in places the path was barely visible. Graham walked ahead at an easy pace without looking back.

A strip of reflective tape appeared at eye level on a rowan to my right. Bright orange, with clean edges, freshly tied.

I stopped.

Graham continued. Euan almost walked into me.

"What?" he whispered.

I pointed. Euan saw it and went still.

The tape was identical to the marker we had found before, the same material, the same height and the same clean-cut edges.

This was not an ordinary path. It was part of a controlled route.

Graham stopped and looked back. "Something wrong?"

"Just checking our position," I said.

After a moment, I began walking again. Euan stayed close behind me.

Another strip appeared about 20 metres farther on, then another. All were at eye level. All had been tied recently.

Euan slowed. I heard his boots scrape as he checked the route behind us and looked back at the markers we had already passed.

Graham noticed. He stopped and turned to face us.

"Fraser," he said. "Keep up."

Euan did not answer.

Graham reached inside his jacket. I recognised the movement before his hand emerged.

He drew a compact handgun. It was small, dark-finished and illegally held. He kept it low, but the muzzle pointed at Euan.

"I said keep up."

I moved before I had time to think. I shoved Euan sideways into the undergrowth and charged Graham in the same motion.

The first shot missed. The crack tore through the trees, and the bullet struck a trunk somewhere to my left.

The second did not miss.

Euan fell hard. I heard him strike the ground and make a sound that was half grunt, half scream.

I reached Graham and caught his gun wrist with both hands, forcing the muzzle upwards and away. He tried to twist free, but I had leverage and would not release him.

We struggled for perhaps three seconds. Then I drove his wrist against a tree trunk.

The handgun dropped.

Graham staggered back. I kicked the weapon away from him, snatched it up by the grip and moved several paces back, keeping the muzzle towards the ground and my finger clear of the trigger.

The crying began.

It was close, perhaps 3 metres away. The same wet, unnatural sound we had heard on the loch.

The air turned suddenly cold, like stepping into a freezer.

I looked up from the weapon.

The pale woman emerged from the fog. The same face had been drawn too tightly and wrongly across its skull. Weed hung tangled through its rope-like wet hair. Its eyes were set too far apart.

It was looking at Graham.

He saw it and ran.

There was no hesitation. He turned and bolted straight into the fog.

I heard his boots striking the path for perhaps five seconds. Then he screamed once.

Then there was nothing.

I made the handgun safe as far as I could, wrapped it in a clean cloth without wiping it and secured it in the top of my rucksack. Then I went to Euan.

He was conscious, but his breathing was ragged. Blood was soaking through his jacket around his shoulder.

"Stay with me," I said.

He nodded but did not speak.

I applied hard pressure with a sterile dressing, then packed additional gauze around it and secured the pad. I could see an entry and exit wound. I could not tell what internal damage the bullet had caused, only that the bleeding could be controlled and that he needed evacuation quickly.

I kept him warm, monitored his breathing and treated him for shock as best I could.

Then I took the emergency whistle from my rucksack and blew three short blasts. The sound came out muted, as if the fog had swallowed most of it. I tried again with the same result.

Euan coughed. "Did it..."

"Quiet. Save your breath."

I helped him towards the landing, supporting most of his weight and moving away from the direction Graham had taken.

I looked behind us once.

The fog remained among the trees, dense, low and motionless. Graham's boot prints led into it. The impressions were filling with water. It was not rain or surface run-off. Water was seeping upwards from the earth and pooling in the hollows left by his boots.

I turned away and kept Euan moving.

At the landing, I used the first-aid kit to reinforce the dressing and keep pressure on his shoulder. His skin was pale and clammy, but he remained conscious and responsive.

I transmitted on the emergency channel, giving our Ordnance Survey grid reference, backed by the GPS coordinates, and a brief summary: two shots fired, one casualty, an armed suspect missing, handgun secured. Police Scotland control acknowledged the message through the rescue coordinator and began sending Police Scotland resources, Lochaber Mountain Rescue Team volunteers and water-search personnel.

It took them three hours to reach us. Darkness, steep ground, poor weather and the remoteness of the landing made a faster response impossible.

Morag arrived by canoe with a medical kit and rescue personnel. Douglas Kerr came overland as a Police Scotland authorised firearms officer because I had reported an armed suspect.

The rescue team placed Euan on a stretcher and began moving him out. I handed the secured handgun directly to Douglas, explained exactly how I had picked it up and stored it, and watched him seal it as evidence.

Douglas remained with me.

"Where's Graham Sutherland?" he asked.

"He ran into the fog."

"Which direction?"

I pointed.

Douglas drew his service weapon and switched on his torch. I followed at his direction, remaining behind him.

We found Graham's boot prints. We found the places where water had filled them. We did not find Graham.

Douglas searched the immediate area for twenty minutes before stopping and turning to me.

"You said he ran?"

"Yes."

"And you heard him scream?"

"Once."

Douglas recorded that in a small notebook. "Anything else relevant to the armed encounter?"

"No."

He studied me for a long moment, then put the notebook away.

We returned to the landing. Morag had gone with Euan. Douglas had me sit on a rock while he updated Police Scotland control. I heard him report a missing armed suspect, a firearm recovered and a continuing search operation.

Then he sat beside me and took my initial statement.

I kept to what I could prove. Graham had appeared at the landing. He had claimed Alison sent him. He offered to guide us by a shorter route. He drew an illegally held handgun and fired twice. The first shot missed. The second passed through Euan's shoulder. I disarmed him and secured the weapon. Graham fled. I heard him scream once and could not find him afterwards.

Douglas wrote it all down.

He did not ask about the crying, the unnatural fog or the woman with the improperly stretched face.

I did not volunteer any of it.

Police Scotland recovered the island cache two days later using the exact grid reference and photographs I had supplied. The equipment remained substantially as Euan and I had found it. The sealed notebook I had removed was already in police custody. I surrendered it when giving my full statement, along with the photographs documenting its original position, and Douglas recorded the compromised handling and my reasons for removing it.

Euan survived. The bullet had passed through his shoulder without striking bone or any major blood vessel. He recovered well enough, but he stopped treating the incidents as a puzzle. He stopped talking about patterns, clusters and BUFORA reports.

When I saw him before leaving Fort William, all he said was, "I'm done."

I did not blame him.

Graham was never found. The search continued for four days and covered 12 square miles. Police Scotland, Lochaber Mountain Rescue Team and trained water-search volunteers found his boot prints and areas of disturbed ground. They found no body, no onward trail and nothing that explained where he had gone.

Alison asked me to complete my report. I documented everything I could support: the staged camps, the reflective markers, the deliberately combed paths, the carved symbols, the island cache, the notebook of initials and dates, and Graham's armed attack.

Taken together, the evidence showed a human predator who had used false cries, marked routes, hidden supplies and carefully staged scenes to control people in remote country. The larger investigation would have to determine how many of Euan's 15 to 20 linked disappearances belonged to Graham, beyond the six recent reports of impossible voices and elevated lights that had first brought me to Lochaber.

I left the rest out. No pale woman. No voice calling for Jamie. No fog moving against the weather. No figure sliding across Loch Garry without disturbing its surface. None of it appeared in my formal report.

I accepted Fiona Mercer's payment and left Fort William on a Tuesday morning in my mud-spattered estate car, following the same route I had taken in: the A82 and its long stretches through glens and moorland.

I had uncovered a documented human predator and witnessed an undocumented presence in the fog that had imposed its own punishment.

I did not know whether I had been investigating that presence or whether it had been using me to expose Graham.

I did not return to find out.
