The Still Water Protocol

The helicopter's rotors hammered the air above me as I pressed my face close to the small window and stared down at the North Sea. Aberdeen had vanished behind us twenty minutes earlier, and there was now nothing in any direction but water. We still had a fair stretch of the flight ahead of us, yet the sea already seemed to have swallowed the land.

It looked unnaturally still for March. There were no white horses and none of the short, choppy waves that usually made offshore flights a stomach-churning ordeal. Only smooth, dark water stretching to the horizon.

My new assignment waited somewhere out there: the Morrow platform, where I was due to begin a fresh rota on 14 March 2026. Another offshore installation. Another crew to learn. Another few months of isolation, surrounded by nothing but steel and sea.

I had done it often enough, but something about that day felt different. Perhaps it was the strange calm below us. Perhaps it was only the usual nerves that came with starting somewhere new.

The pilot's voice crackled through my headset. "Platform ahead. Weather's been kind today. Should be a smooth landing."

I nodded and tried to shake off the mood that had settled over me during the flight. First-day nerves, that was all. Every new platform felt strange until you found your place among the crew and settled into the routine.

Morrow appeared gradually through the haze, a metal island rising from the water on massive support columns. It looked like a standard installation: derrick, accommodation block, machinery spaces, stores and helideck. I had seen dozens like it.

The pilot brought us down with practised ease. As the rotors began to slow, I picked up my weatherproof kit holdall and climbed out. Four men waited near the helideck, squinting into the rotor wash. With me, that made five people aboard Morrow.

The tallest stepped forward first. From his stance and the better quality of his workwear, I took him for the man in charge.

"Euan Mercer?"

He had to shout over the helicopter.

"That's me."

"Graham Hargreaves. Offshore installation manager."

His handshake was firm, his palm roughened by years of practical work.

"Welcome to Morrow."

"Thanks. Good to be here."

Graham gestured towards the others. "Let's introduce you to the crew."

Two of them came forward with easy smiles.

"Imran Qureshi, though everyone calls him Im. And Peter Walsh - Pete."

They seemed relaxed and ordinary, exactly the sort of men I expected to meet on any North Sea installation. The fourth man remained near the edge of the helideck, and there was something about him that caught my attention.

He stood with his shoulders hunched and his arms wrapped around himself as if he were freezing, although the afternoon air was mild by offshore standards. His gaze stayed fixed on the deck.

"And that's Callum Strachan," Graham said, lowering his voice slightly. "Cal's been with us for about eight months."

Cal did not acknowledge the introduction. He shifted from foot to foot, his hands trembling at his sides. He looked as though he had not slept for days. There were dark hollows beneath his eyes, and his skin was pale and drawn.

The helicopter lifted behind us. Graham raised a hand to the pilot, then turned back to me once the aircraft had pulled away.

"Let's get you settled. Im, Pete, can you finish the afternoon equipment checks?"

"No bother," Im said.

He picked up a toolbox and headed towards the drilling area with Pete beside him. Graham waited until they were beyond earshot, then stepped closer.

"I need to tell you something. Cal had a rough morning."

"What happened?"

"He saw something in the water. Whatever it was, it shook him badly."

"What sort of thing?"

"Hard to say. He hasn't been very clear."

Graham glanced towards Cal, who had moved farther away and was now clutching the safety rail.

"It might have been debris or marine life, but he's frightened. Properly frightened."

I watched Cal for a moment. Graham was right. This was not mild anxiety or confusion. The man looked terrified.

"Has he had trouble before?"

"Nothing like this. He's always been quiet and keeps himself to himself, but he's dependable. A good technician. Something changed this morning."

Graham rubbed at his jaw.

"I thought you should know what you're walking into."

The situation felt wrong, but I had seen men buckle under the pressure of offshore life before. Isolation could distort ordinary things until they seemed threatening. Lack of sleep did the rest.

"I'll keep an eye on him."

"I'd appreciate it. You've dealt with crew problems before."

"A few." I adjusted the strap of my holdall. "Usually things settle once everyone gets back into a routine."

Graham nodded, although the tension did not leave his face. "I hope you're right. Come on. I'll show you round."

Before we went inside, I decided to try speaking to Cal. He needed to know the new arrival was not going to avoid him or treat him as a problem.

"Cal."

I walked over to the rail.

"I'm Euan. The new bloke."

His head turned slightly, but he still would not meet my eyes. Up close, the shaking in his hands was worse than I had first realised. His breaths were shallow and rapid.

"This morning," he said. His voice was hoarse and broken by long pauses. "There were things. Things that shouldn't be there. Not that deep. Not moving like that."

"What kind of things?"

"Shapes under the water. Too big."

At last he looked at me. What I saw in his eyes was not the vague agitation brought on by too much caffeine and too little sleep. It was the focused terror of someone who believed he had seen something impossible.

"They were coordinated," he said. "Like they knew what they were doing."

I kept my tone light. "The sea's full of odd things. It might have been a shoal of large fish, or debris drifting off a North Sea shipping route. Light and water can play tricks on you, especially when you're exhausted."

"No."

He shook his head violently.

"Not fish. Not debris. Something else."

I was running out of ways to reassure him without sounding patronising.

"I know the water can get to you when you've been out here for weeks. I've seen strange things myself. Most of them turn out to be ordinary once you get a proper look. What do you reckon it was, a sea monster? Maybe we've got a genuine kraken down there. That would make a story for the pub when we get ashore."

Cal stared at me as if I had suggested setting fire to the platform. The joke landed badly. If anything, he looked more frightened.

"Don't joke about it."

His voice fell almost to a whisper.

"Please don't joke about it."

Behind us, I heard Im and Pete speaking quietly near the stores. When I glanced back, they were watching us with open concern. Im caught my eye and gave a small shake of his head, warning me not to press Cal further.

Graham cleared his throat.

"Euan, let me get you familiar with the layout."

I followed him towards the accommodation block, leaving Cal alone at the rail. He did not move. He simply stared down at the water, gripping the metal bar so tightly that his knuckles had turned white.

"Night watch begins at 20:00," Graham explained as we crossed the common room. "You'll be paired with Pete for your first week, then we'll review it. Meals are at 06:00, 12:00 and 18:00. Standard rota."

The accommodation was exactly what I expected: compact, functional rooms, each containing a narrow bunk, a desk and enough storage for personal kit. Graham showed me to an empty cabin at the end of the passageway.

"This one's yours. Nothing luxurious, but you've got privacy and the heating works."

He nodded towards the foot of the bunk, where I set down my holdall.

"Any questions?"

"Seems straightforward."

I sat on the edge of the bunk and tested the mattress. It was firm without being uncomfortable.

"How long have the others worked together?"

"Im and Pete have been here about six months. Cal joined two months after them. They're a good group. Everyone knows the job, and there haven't been any serious clashes."

He paused.

"Not until this morning, at any rate."

Through the small porthole, I could still see Cal at the rail in precisely the same position. The sight made my stomach tighten, though I could not have said why.

"He'll probably improve once he gets some sleep," I said, more to persuade myself than Graham.

"Maybe." Graham did not sound convinced. "I'm not trying to burden you with this on your first day, but keep your eyes open. Cal isn't prone to imagining things, and the state he's in worries me."

The admission surprised me. Managers generally played down crew problems, especially in front of a new contractor who might begin wondering what sort of operation he had joined. Yet Graham seemed concerned not only about Cal's mental state, but also about whatever had caused it.

"You think he really saw something unusual?"

"I think he saw something that frightened him badly enough to make him question his own sanity. Whether the thing itself was unusual..."

Graham shrugged.

"That's harder to answer."

We returned to the common areas, passing the galley and the small recreation room where men off duty could watch films or play cards. Everything was clean, maintained and reassuringly ordinary. Graham also showed me the radio room and explained that he held the platform's senior systems access because he was responsible for the communications array, automated telemetry, emergency beacon and security-camera network as well as the operational rota.

Nothing looked neglected, yet tension seemed to hang in every passageway.

Im and Pete were finishing their equipment checks, calling readings to one another as they worked through a list. They spoke with the ease of men accustomed to working together. I saw nothing unusual in what they were doing, but both kept glancing towards Cal, who remained motionless at the rail.

"Dinner's in about an hour," Graham said. "That gives you time to unpack. Pete can show you the drilling areas afterwards."

"Sounds good."

Graham started back towards the main work area, then stopped.

"Euan, thanks for coming aboard. I know the notice was short. We needed someone experienced, and Firth Energy Services spoke highly of your record."

"Happy to be here."

It was the expected answer, but as I said it, I realised I was not sure it was true. Something about Morrow felt wrong. I could not identify what it was. Perhaps Cal's fear had infected the rest of us. Fear travelled quickly through a small group, particularly when that group was isolated. One man's paranoia could unsettle an entire crew if it was not handled carefully.

Yet when I looked at the pale sunlight glinting on the platform's steelwork, I found myself thinking of the water we had flown over. The North Sea was notorious for rough conditions, especially in early spring. Seeing it so still felt unnatural.

I pushed the thought aside and returned to my cabin.

First-day nerves. That was all.

By morning I would have my bearings. The crew would settle. Cal would sleep and recognise that whatever he had seen had a rational explanation. Routine would take control.

At least that was what I told myself as I unpacked my kit and tried to ignore the unease that had followed me from the helicopter.

The second day began with me leaning against a cold metal rail, strong tea cooling in my battered insulated mug. The sea looked exactly as it had the day before.

That same impossible stillness lay over it. No white horses. No swell breaking against the columns. Only a smooth black surface beneath a grey morning sky.

I kept telling myself it was an unusual weather pattern, but looking at the water made my skin crawl.

I could not stop thinking about the Caledonia Deep platform. Its site had lain roughly 200 kilometres north-west of Morrow, far enough away to be dismissed as unrelated, yet close enough to haunt every installation in that part of the North Sea.

The story had made headlines about a year earlier, although most of the details vanished so quickly that anyone not paying attention would have missed them. An entire drilling platform had disappeared without warning. One day it was operating normally. The next, search-and-rescue crews found only scattered wreckage in empty water.

The official account changed repeatedly. First there had been a catastrophic structural failure, then an explosion, then a freak weather event. Government investigators arrived within hours, and by the end of the week nearly everything had been classified. No final report was published. The families never received a convincing explanation of what had happened to the people aboard.

The gossip that followed was wild. Men in Aberdeen pubs spoke of cover-ups and secret government experiments. Some claimed Caledonia Deep had drilled too far and disturbed something that should have remained buried. Others told stories about strange transmissions received by nearby platforms in the days before the loss: radio traffic with rhythms and structures that matched no recognised communications protocol.

I had laughed at most of it. Offshore workers loved conspiracy theories, particularly after a few pints. Every accident became a government plot, and every equipment failure became evidence of something supernatural. It was one way of living with the fact that we worked in an industry where a minor fault could kill people.

But with the same dark sea lying motionless beneath me, those stories no longer seemed entirely ridiculous. The water felt different, as though something enormous were moving beneath the surface, just beyond the limit of sight.

Slow, unsteady footsteps sounded behind me. I turned and saw Cal crossing the deck.

My stomach dropped. If he had looked ill the previous afternoon, he now looked close to death. His skin was grey, and the shadows beneath his eyes resembled bruises. His hands shook constantly.

"Euan."

His voice was a rasp beneath the machinery's steady thrum.

"Morning, Cal. Did you get any sleep?"

He gave a bitter laugh that sounded more like a cough.

"Sleep. Right."

He came to the rail beside me and gripped it with both hands.

"I tried. I kept hearing things."

"What sort of things?"

"Voices from the water."

He stared at the black surface, trembling from head to foot.

"Not voices exactly. More like singing, but it wasn't human singing."

I set my insulated mug on a nearby equipment case and kept my voice level.

"It might have been the wind passing through the support structure. You can get strange sounds from the steel at night."

"No."

Cal shook his head frantically.

"This was different. It came from below. Far below."

He leaned over the rail and pointed.

"Can you see them? The shapes?"

I followed his finger. There was nothing but smooth water reflecting the grey sky.

"I can't see anything."

"They're there. They're moving in patterns. Coordinated patterns."

His voice dropped to a whisper.

"Watch about sixty metres out from the seaward rail. They've been circling for hours."

I concentrated on the area he indicated until my eyes watered. For a moment, I thought I saw something: a slight break in the surface, perhaps, or a shadow moving against what little current there was. When I blinked, it was gone.

"Cal, I think you need proper rest. When did you last sleep through the night?"

"You don't believe me."

His shoulders sagged, and for a moment I thought he might cry.

"That's fine. Graham doesn't believe me either. None of you do."

"It isn't that I don't believe you saw something. There are plenty of explanations for movement in the water. Large fish travel in shoals. Debris can be carried by subsurface currents."

"No."

The word was sharp enough to stop me.

"I know what fish look like. I know what debris looks like. This is different. They're too large, too deliberate, too intelligent."

Something cold passed through me when he said the last word. There was a certainty in his voice that did not sound like vague hallucination. He was describing a detailed observation he believed he had made in full possession of his senses.

"What do you mean by intelligent?"

Cal turned fully towards me. His eyes were bloodshot and desperate.

"They move as if they're thinking. As if they're planning. When one group changes position, the others adjust. When they turn, they all follow, but not at the same moment. It's like they're communicating."

I wanted to tell him how absurd it sounded, but his expression stopped me. This was not random paranoia. His account was specific and consistent.

"How long have you been watching them?"

"Since before dawn. I couldn't sleep, so I came out at about 04:00. They were already there, waiting and moving in slow circles around us."

He gestured towards the water.

"They're getting closer. The circles are tighter than they were."

Before I could reply, Graham's voice carried across the deck.

"Cal, Euan, break's over. I need you both in the drilling area."

Graham stood outside the main structure with his hands on his hips, plainly losing patience. When I turned back, Cal was still staring into the sea.

"Come on. Graham wants us back at work."

"Just promise you'll keep watching. Whenever you can. Don't let your guard down out here."

"I'll keep an eye on it," I said, although I did not know what I had promised to look for.

Cal reluctantly released the rail. I collected my mug and followed him, but his words remained with me.

Too intelligent. Too deliberate.

I tried to concentrate on the work Graham assigned: routine maintenance on the drilling equipment, sensor adjustments and hydraulic-pressure checks. It was ordinary offshore work and should have occupied my mind. Instead, every few minutes I caught myself looking towards the sea.

It remained perfectly flat. The calm that had bothered me since the flight now seemed charged with intent. I searched it for patterns, trying to detect movement beneath the surface.

During a short break, I went to the platform's edge and studied the water more carefully. The low morning sun struck it at an angle, making it difficult to see below. Anything deep enough would have been invisible from our height.

As I watched, however, I thought I saw a minute distortion, as though something immense had passed just beneath the surface and raised a ripple that vanished at once.

I looked away and returned to work.

That was how suggestion operated. Cal had planted the idea in my mind, and now I was turning harmless movement into evidence. Even so, I continued checking throughout the shift. Whenever I went near an edge, my gaze dropped to the water. Whenever Graham sent me for tools or readings, I found some reason to pass a rail.

The sea no longer seemed peaceful. It felt like the silence before a storm, the sort of hush that made you hold your breath while waiting for something you could not name.

I was checking a pressure gauge when Im's voice cut through the morning air.

"Euan! Graham! Get over here now!"

The panic in his voice sent a jolt through me.

I left the gauge and hurried towards the north-eastern support columns, where he had been carrying out an inspection. Graham emerged from the equipment bay at the same time, moving faster than I had seen him move since my arrival.

Im stood at the edge, clutching the safety rail. His face had lost all colour. He stared down with an expression suspended between horror and disbelief.

"What is it?" Graham called.

"There's a body down there."

Im spoke with forced calm.

"It's caught between the support columns."

I reached the rail and looked over. At first I saw only the dark water that had unsettled me since the previous day. Then my eyes adjusted.

A shape rose and fell almost imperceptibly between two of the great steel columns supporting Morrow. It was human, or had once been. Even at that distance, something was clearly wrong. Its limbs rested at unnatural angles, and dark stains surrounded it in the water.

"Christ," Graham muttered.

He leaned out to see more clearly.

"How long has it been there?"

"It must have arrived overnight," Im said. "I checked this section yesterday evening. There was nothing here."

For several seconds, none of us spoke. Someone had died, apparently by violence, and the body had drifted to an isolated platform far from any other installation or recognised North Sea shipping route.

Graham straightened.

"We have to recover it. We can't leave it among the supports."

"Shouldn't we radio it in first?" I asked. "Get the authorities involved before we touch anything?"

"We'll make the call, but we need to secure the body before it drifts away."

He was already heading towards the stores.

"Im, prepare the recovery winch. Euan, get tarpaulins."

I wanted to object, but the current, slight as it was, might still carry the body beyond reach. If that happened, there would be no chance of identifying the victim or determining what had occurred.

The recovery took nearly an hour. Im operated the winch while Graham and I guided the cable between the columns. Securing the harness was the worst part. The remains were badly damaged, and we had to avoid causing further injury while gaining enough control to lift them.

When the body finally reached the deck, my first instinct was to turn away.

Part of an obsolete orange survival suit clung to the corpse, bleached and abraded by the sea. No name, company mark or visible feature identified the victim. The flesh beneath had been opened by repeated wounds across the torso and limbs. Each wound belonged to a parallel group, the same narrow spacing recurring again and again. Some had cut down to the bone.

The pattern was too precise and too extensive to resemble any accident I knew.

"What could do that?" Im whispered.

He crouched nearby, taking care not to touch the remains.

"A vessel's propeller?"

I forced myself to examine the injuries. The cuts were clean, but they did not radiate or overlap in the chaotic fashion I would have expected from machinery.

"It doesn't look like propeller damage. The wounds are too deliberate. They're arranged in repeated groups."

Graham moved to the external radio point.

"Aberdeen Marine Control, this is Morrow platform. We have an emergency requiring immediate assistance. Over."

Static flooded the speaker. It crackled and surged with a density I had never heard on an offshore channel.

Graham changed frequency.

"Aberdeen Marine Control, Morrow platform. Emergency assistance required. Please respond. Over."

The static continued. He worked through the emergency frequencies, then tried contacting nearby offshore traffic. Every channel gave him the same wall of white noise.

"Atmospheric interference?" Im suggested, though he sounded unconvinced.

"I've never known it this severe," Graham said. "We should hear something, even if it's only traffic from another installation."

He turned towards the radio room, which was about six metres away, intending to test the main console and diagnostic system.

I was still looking at the body when I noticed Cal at the far edge of the deck. He was hunched over the rail in his usual place.

"Cal," I called.

He did not respond.

"You need to come and see this."

He turned at last. The instant he saw the corpse, his reaction was violent. His face went white and he stumbled backwards as if something had struck him.

"No. No, no."

The words emerged in a low, rhythmic chant.

"It's not meant to be here yet. It's too soon."

"Cal, it's all right."

I moved towards him, but he was already backing away.

"Don't look at it. Don't touch it."

He shook his head frantically as he retreated towards the main structure.

"They're watching. They know we found it."

"Who is watching?" Graham demanded, abandoning the radio controls. "What are you talking about?"

Cal had already vanished around the equipment bay. His footsteps rang along the metal walkways and faded into the platform.

Graham looked from the corner where Cal had disappeared to the mutilated body on the deck.

"This is coming apart quickly. Im, help me cover it."

We wrapped the remains without disturbing them further and transferred them to a secured external recovery area, isolated from the accommodation and workspaces. The obsolete orange fabric was the last thing I saw before we fastened the covering and locked the barrier.

"We'll try the radio again in an hour," Graham said.

We spent the rest of the day making repeated attempts, but the interference never cleared. It grew thicker until it seemed less like ordinary static than a signal designed to occupy every available frequency.

Graham suspended non-essential operations and restricted movement to necessary areas. He also checked the main radio diagnostics, the automated telemetry and the emergency beacon. Each system reported faults that should not have occurred together. Because he held the senior technical permissions, he was the only person aboard with unrestricted access to all three systems as well as the camera controls. He said he would inspect the configuration logs himself.

Without communications, telemetry or a functioning beacon, no missed routine check-in would automatically bring rescue. We were cut off without the shore systems necessarily knowing anything was wrong.

The covered body remained locked in the external recovery area, an unseen presence that none of us could forget. We did not discuss the grouped wounds or speculate about what might have inflicted them. Some conversations made sleep impossible.

Cal avoided the recovery area. I glimpsed him several times at the outer edges of the platform, always watching the sea. Whenever one of us approached, he slipped away. It was as though he wanted to avoid not only the body but the rest of us.

By late afternoon, Graham imposed full emergency procedures. Everyone was to remain in pairs. Nobody was to work alone, and each pair had to report to him every two hours.

It was the sort of response expected after a serious incident or critical failure. Yet the mood felt less like accident management than preparation for an event none of us wished to name.

Evening arrived with disconcerting speed. Perhaps time only seemed distorted after everything that had happened. The platform lights came on automatically, whitening the steel and deepening every shadow beyond their reach.

Graham called a crew meeting in the common room for 20:00. The hour arrived and passed. He did not appear.

Im, Pete and I waited several minutes before trying to contact him. When he failed to answer, we began searching.

His cabin was empty. His personal belongings were untouched. We checked the radio room, the machinery areas, the stores, the engine room and every accessible workstation. We also inspected the secured external recovery area. The barrier remained locked, and the covered body was still inside.

Graham was nowhere on the platform.

"When did either of you last see him?" Im asked when we regrouped.

I searched my memory.

"At about 18:00. He was still working on the radio faults and system logs."

"I saw him later," Pete said quietly. It was the first thing he had contributed for some time. "At about half past seven. He was heading towards the north-eastern edge, close to the recovery area."

We went there immediately. The secured area was undisturbed, and the covered corpse remained where we had left it. There was no sign of Graham. The safety rail was intact, with no damage or scuffing to suggest a fall or struggle.

"Could he have gone over?" Im asked, though without conviction.

I walked the perimeter, examining every section of rail and every place where someone might have slipped. Everything was correctly fitted and well maintained.

Then I realised we had not seen Cal for hours.

"Where's Cal?"

Im and Pete looked at one another. Neither had seen him since earlier in the day, when he fled from the recovered body.

We repeated the search, checking every cabin, store, machinery recess and possible hiding place. Cal's room was empty. His clothes remained in the drawers, his toiletries stood beside the basin and a half-finished sudoku book lay open on his desk, a pencil resting across the page.

Cal himself was gone.

"This doesn't make sense," Im said. "Two people don't simply disappear from an offshore platform."

Pete stood at the porthole, gazing into the dark sea.

"Maybe they didn't disappear. Maybe they left."

"Left how?" I asked. "There's no vessel and no helicopter. We're in the middle of the North Sea."

"They could have..."

Pete stopped.

"They could have what?"

"Jumped."

The word hung between us.

I wanted to dismiss it, but after Cal's deterioration, the mutilated body, the failed radios, the dead telemetry and the disabled beacon, I could no longer reject the possibility outright.

"We need the security recordings," Im said. "If anything happened, the cameras may have caught it."

Morrow's security network was basic but adequate, with cameras covering the principal work areas and critical access points. Im led us to the monitoring station.

The recordings showed ordinary activity through most of the day. We watched ourselves work, recover the corpse and carry supplies across the deck. Graham appeared on several feeds, testing communications, examining systems and supervising the emergency measures.

We searched first for Cal. The cameras showed him at intervals, always alone, always near an edge and staring at the water. His final intact appearance was timestamped 18:47. He walked towards a blind area beyond the camera coverage and did not return.

Cal had vanished nearly an hour before the rest of the system failed.

We then tracked Graham. The final clear image showed him crossing towards the north-eastern side at 19:34. He moved purposefully, as if responding to something or going to complete a task. The camera followed until he entered the same blind area near the external recovery enclosure.

At that exact moment, its picture collapsed into static.

Within seconds, every other feed failed as well.

"An equipment fault," I said, though I no longer believed that anything aboard Morrow had a simple explanation.

Im advanced through the remaining footage. Every channel showed the same sequence: normal coverage until 19:34, then uninterrupted static.

The timing was too precise. The cameras had not failed when Cal disappeared at 18:47. The general failure began only when Graham, the man with full access to the security, communications, telemetry and beacon systems, reached the blind area.

Whether he had sabotaged them willingly, acted under compulsion or merely walked into a trap, I could not tell. But the damage suggested intent and technical knowledge.

"So they're both gone," Im said, exhaustion flattening his voice. "Two men vanished from a secure platform in the middle of the sea."

I stared at the static-filled monitors.

"We need to secure ourselves. Whatever is happening, we can't assume it's finished."

Pete nodded, but his expression remained distant, as though part of his attention had turned elsewhere.

Im looked around the monitoring station.

"The medical bay. It's the most secure room aboard. Reinforced door, independent power and a separate emergency radio."

It made sense. The medical bay had been designed to serve as a refuge during serious incidents, with heavy-duty locks and communications independent of the main network.

We gathered what we could carry: drinking water, packaged food, first-aid supplies, torches and basic tools. Before withdrawing, we checked the external recovery area once more. The lock remained secure, and the covered body was still present.

The platform no longer felt like a workplace. It had become a trap. Every shadow appeared deeper, and every vibration through the steel suggested footsteps.

The medical bay was compact but well equipped, with solid walls and a door that locked from within. We dragged the heaviest movable furniture against the entrance, creating a barricade that might at least delay anyone trying to force their way inside.

"The emergency radio's dead as well," Im reported after testing the independent set. "Same interference."

I sank into one of the medical chairs and allowed the weight of our situation to settle over me. Two crewmen were missing and possibly dead. Every means of communication had been cut. The cameras, telemetry and beacon had been disabled. The three of us were trapped on an isolated platform with no way to call for help.

"It has to be connected to the body," I said. "Everything began to fail after we brought it aboard."

"You think someone killed that person and is coming after us?" Im asked.

I had no answer. The events felt too coordinated for random violence, but every alternative was worse.

Pete had remained quiet while we barricaded the room, moving mechanically and following our instructions without comment. Now he stood at the medical bay's small window and gazed into the darkness.

"Pete, are you all right?" I asked.

He turned. There was an odd remoteness in his expression.

"I found something in Cal's room while you and Im were checking the camera recordings."

He took a folded sheet of paper from his pocket. Cal's handwriting covered it, but the lines were so hurried and cramped that they were barely readable. It looked as though he had written in a panic.

"It was in his desk drawer," Pete said. "Hidden beneath some papers."

He handed it to me.

I unfolded the sheet and tried to decipher it. Most of the writing was illegible: desperate scratches that might have been words or might have been meaningless marks. Scattered through the chaos, however, were several phrases I could make out.

The depths were calling. There was no choice left. Joining the collective, they had shown him the truth.

Mixed through the text were symbols unlike any alphabet I had ever seen. Geometric patterns and curved lines flowed into one another, creating designs that hurt if I looked at them for too long.

"What does it mean?" Imran asked, reading over my shoulder.

"I have no idea."

I studied the note more closely, trying to find some pattern or logic in Cal's final written words. He had written it recently. The ink was still fresh.

Pete moved closer to examine the symbols. As his eyes settled on the strange markings, his expression became increasingly fascinated, as though he could see something the rest of us could not.

"These symbols," he said softly. "They're not random. There's a pattern here. A structure."

I looked again, but all I saw were chaotic scratches and desperate words. If there was a pattern, it was completely invisible to me.

Pete kept staring at the paper with growing intensity, and something in his expression made me deeply uneasy. It was the same look Cal had worn while staring down at the water: the look of someone seeing things that were not there, or things that should not have been there.

I spread Cal's note across the small medical table, smoothing the creases as carefully as I could with shaking hands. The paper itself was unremarkable, but its contents made my skin crawl every time I looked at them.

Imran pulled his chair closer and squinted at the frantic scrawl.

"Half of this is completely illegible. Look at these marks here. Are those even letters?"

I ran my finger along a section where Cal's handwriting had degenerated into jagged scratches.

"I think he was writing quickly. Maybe he was panicking. But some of these phrases are clear."

I pointed to a line near the middle of the page.

"Submersion protocols."

"What does that mean?"

"Could be diving procedures," Imran suggested, although there was no conviction in his voice. "Emergency protocols for getting people off the platform if it starts going down."

Imran and I exchanged glances. Pete's tone had changed, taking on an analytical quality that reminded me uncomfortably of Cal's final behaviour. It was the same focused intensity he had shown while staring into the water.

"They look like random scratches to me," Imran said. "Cal was having a breakdown. None of this means anything."

"No, look."

Pete took a pen from the medical station and copied one of the symbols onto a separate sheet of paper.

"This one appears six times throughout the note, always in the same position relative to references to water or depth. And this one..."

He moved to another symbol.

"This one always appears near references to consciousness or awareness."

I studied the copies, trying to see what Pete meant. The marks did repeat, but I could not discern any meaningful pattern. They looked like the sort of doodles someone might make during a telephone call: meaningless geometric shapes and curved lines.

"Even if there is a pattern," I said, "that doesn't mean it makes sense. People suffering a mental collapse often become obsessed with meaningless details. They see connections that aren't really there."

Pete looked up from his copying with an expression I could not read.

"Maybe. Or maybe Cal understood something we don't."

That possibility troubled me more than I cared to admit. If Cal had discovered something real before he vanished, our situation might be worse than I had imagined.

"I'm going to check the communications equipment again," Pete announced, rising abruptly. "If Graham and Cal sabotaged it, there may be evidence of how they did it."

Imran began to object.

"We agreed to stay together. Nobody works alone."

"The radio room is about six metres away. You can see the door from here if you leave the medical bay open." Pete was already moving towards our barricade. "I need to examine the equipment properly. If they disabled it deliberately, we might be able to repair it."

The reasoning made sense, even though I hated the idea of separating. Imran helped me shift enough furniture for Pete to squeeze through the doorway. Then we put everything back except for a narrow gap through which we could monitor his movements.

Through the gap, I watched Pete disappear into the radio room. The platform's emergency lighting made the passageways look distorted and threatening. Every few minutes, I glimpsed him moving among the equipment, inspecting connections and checking circuit panels.

"Found anything?" I called after he had been working for nearly an hour.

"Yes."

His voice carried back with an odd note in it.

"Yes, I've found something."

Pete emerged carrying a handful of cables and circuit boards. His expression was grim as he approached our barricade.

"They knew exactly what they were doing," he said, placing the components on the medical table. "Look at these cuts. Clean and precise, made with the proper tools. They didn't simply smash the equipment. They systematically disabled every primary and backup communications system, along with the automated telemetry and the emergency beacon."

I examined the severed cables. The cuts were neat, made with wire strippers or similar tools. This was not the random destruction of someone in the midst of a psychotic episode. It was planned sabotage by people who understood the platform's systems. Graham, as offshore installation manager, had the access and technical knowledge to do it, although that did not explain whether he had acted willingly.

"But why?" Imran asked. "Why would Graham and Cal cut us off from the outside world?"

"Perhaps they didn't have a choice," Pete said quietly. "Perhaps something made them do it."

The implication struck me hard. If Graham and Cal had been compelled to isolate us, their disappearance was not random. It formed part of a larger design.

"Made them do it how?" I asked. "Mind control? Hypnosis? That's science fiction."

Pete returned to Cal's note, tracing the strange symbols with his fingertip.

"I don't know. But these symbols are starting to make more sense."

"No, they're not," Imran said firmly. "They're meaningless scratches made by someone who had lost his mind. Don't follow Cal down the same path."

Pete did not listen. He found another pen and began copying symbols onto a clean sheet, adding details and joining lines that I could not see in the original. He looked more confident now, as though he were deciphering a language he had begun to understand.

The platform shuddered beneath us. At first I assumed it was normal movement. Offshore installations responded constantly to wind and sea conditions. Then it happened again a few seconds later, accompanied by a deep groan that seemed to rise from far below.

"What was that?"

Imran moved to the little window and pressed his face to the glass, looking down towards the sea. Another groan travelled through the platform, longer this time and possessing a metallic quality unlike any ordinary structural strain. It vibrated through the walls and produced harmonics that made my teeth ache.

"The platform's under stress," I said, trying to persuade myself as much as Imran. "A storm may be coming in. The weather changes quickly out here."

But the small weather monitor in the medical bay showed calm conditions. There was no wind, no heavy swell and nothing that could account for the movement.

The groan came again. This time it sounded almost deliberate. It was not merely the random complaint of ageing metal. Something appeared to be pressing against particular parts of the structure, testing the platform's strength from below.

"We should take watches," I said. "One of us needs to remain awake while the others rest."

Imran nodded and sat in one of the medical chairs.

"I'll take first watch. You two try to sleep."

Sleep seemed impossible, but exhaustion was overtaking me. Two days of fear and unrelenting tension had left me drained. I stretched out on the examination couch and used folded towels as a pillow. Pete settled near the table where Cal's note lay open. Even after lying down, he continued staring at the symbols in a way that disturbed me.

"Pete, you need to rest. Staring at that thing all night won't help."

"Just a few more minutes," he murmured. "I'm beginning to see how they connect. The patterns are becoming clearer."

I wanted to argue and tell him that he was following the same path that had led to Cal's collapse. I was too tired. Despite the hard couch and the threatening noises, I drifted into sleep.

My dreams were strange and terrifying: dark water, unfamiliar symbols carved into metal and voices calling from impossible depths. I woke repeatedly, never knowing what had disturbed me. Each time I saw Imran's silhouette beside the window, still keeping watch, and Pete bent over the table, studying the note beneath the dim emergency lights.

Morning brought no relief. The platform had groaned throughout the night, the sounds falling into something almost like a pattern. The emergency lighting made it difficult to judge the hour, and I felt as though I had barely slept.

"Any change?" I asked Imran as I sat up and tried to ease the stiffness in my back.

"The noises became worse at about 03:00. More frequent and more intense."

"And Pete?"

He gestured towards the table.

I turned, and my stomach dropped. Pete had covered the medical table with paper. Dozens of sheets bore symbols resembling those in Cal's note, except these were larger and more elaborate, with flowing lines forming patterns across several pages.

"Pete, what is this?"

He looked at me with oddly distant eyes.

"I've worked it out. The structure. The meaning. It isn't exactly a language. It's more like a map. Or perhaps instructions."

"Instructions for what?"

"For understanding. For accepting the invitation."

His voice had acquired the same dreamlike quality Cal's had possessed during his final conversations.

"They're not random, Euan. They're a path to something greater."

Imran approached the drawings.

"Pete, you've been awake all night drawing nonsense. You need to rest. Eat something. Clear your head."

"It isn't nonsense."

Pete stood and gestured towards the network of symbols.

"Look at the connections. Look at the way each element builds upon the last. This is communication, simply not in any form we were taught to recognise."

I studied the papers more carefully, trying to see what Pete described. The symbols were joined by flowing lines, creating patterns that seemed to move when I stared at them for too long. To me, they remained the obsessive drawings of a man losing his grip on reality.

"Communication with whom?" I asked.

Pete turned back to his work, adding more symbols with swift, confident strokes.

"With them. The ones below. The ones who have been waiting."

The casual certainty with which he spoke frightened me. He was not speculating or giving voice to a fear. He spoke as though stating something everyone already knew.

"Pete, listen to me."

I moved closer and tried to capture his attention.

"You're displaying the same behaviour Cal showed before he disappeared. You need to step away from this and focus on our actual situation."

"Our actual situation is precisely what I'm focusing on."

Pete added another symbol to the growing network.

"We aren't trapped here by accident. We were brought here. Selected for this purpose. The others understood eventually."

"What others?" Imran demanded.

"Graham and Cal."

"They're dead, Pete. Or they lost their minds and killed themselves. That's what will happen to us if we don't find a way off this platform."

Pete finally looked up. His face was utterly calm.

"Dead isn't the right word. They've passed beyond physical limits. They've joined something larger and more important than individual existence."

"You're talking about suicide," I said bluntly. "That is what you're describing."

"I'm talking about evolution. About accepting an invitation to become part of something beyond our limited understanding."

Pete returned to the symbols, adding detail with every stroke.

"The pattern is almost complete. Soon I'll understand enough to make the transition."

Imran seized my arm and pulled me away from the table.

"We can't let him continue. He's suffering the same collapse as Cal."

"I know," I whispered. "But what can we do? We're trapped here with him."

"Perhaps we don't have to remain trapped."

Imran lowered his voice further.

"Perhaps there's another option."

"What do you mean?"

He glanced at Pete, who remained absorbed in his drawing, then turned back to me.

"I've been thinking about what happened to Graham and Cal. Perhaps they made the sensible choice."

"You're talking about killing ourselves."

"I'm talking about ending this on our own terms instead of waiting for whatever took them to come for us."

His expression was grim but resolute.

"Look at Pete. Look how quickly he's deteriorating. In another day or two, there'll be nothing left of him. Do we really want to wait and see what comes next?"

The suggestion terrified me, but I could not dismiss it entirely. Our situation seemed hopeless. We were stranded on an isolated platform without communications or any means of calling for help, while our colleagues disappeared or lost their minds. If something was taking us one by one, perhaps a swift death would be better than what had happened to the others.

"There must be another way," I said. "Rescue teams will start looking for us eventually. When we miss the next scheduled check-in, Aberdeen Marine Control will send someone to investigate."

"When is the next check-in due?"

I tried to recall the communications schedule. Routine reports could be days apart for a platform with such a small maintenance crew. More importantly, Graham and Cal had disabled the automated telemetry and emergency beacon along with the radios. Whatever was happening ashore, no alert had triggered a response. I did not yet know that the Centre was suppressing or spoofing those shore-side warnings.

"It could be days before anyone realises something is wrong," I admitted.

"And when they do come," Imran said, "what makes you think they'll find anything? Whatever happened to Graham and Cal could happen to the rescue crews as well."

The reasoning was bleakly convincing. If an unknown force was taking crew members, additional people would merely provide more victims. If the source lay in the water surrounding the platform, vessels approaching along the North Sea shipping routes might be just as vulnerable.

"I'm not giving up," I said. "Not yet. There has to be an explanation for this. Something rational that we can understand and perhaps counter."

"Like what Pete is doing? Trying to communicate with whatever is down there?"

I glanced at Pete. He had left the table and was drawing symbols directly onto the medical bay wall. His movements had become increasingly frantic, as if he were racing to complete some essential task.

"No. Not like that. Pete is losing contact with reality, following the same path Cal took. But perhaps there's a middle ground. Perhaps we can determine what is really happening without losing our minds in the process."

"Understanding the pattern," Pete said suddenly, his voice carrying clearly across the room. "Accepting the invitation."

He had been listening, but he had interpreted our conversation in a way neither of us intended. To Pete, our discussion of a rational explanation had become confirmation of his symbols.

"The transition is beginning," he continued, adding another elaborate figure to the wall. "Soon the barriers will dissolve entirely."

Imran and I watched in horror as he covered more of the medical bay. The symbols flowed together into patterns that hurt to look at. Pete worked with increasing speed and confidence, as though he knew precisely what he was doing.

"We have to stop him," Imran whispered.

"How? He isn't violent. He hasn't threatened us directly. If we try to restrain him, he may become dangerous."

"He's already dangerous. Look at him. He's completely detached from reality. In a few more hours, he'll be just like Cal before he disappeared."

I had to concede that Imran was right. Pete was deteriorating in exactly the same way: obsessing over the symbols, becoming unresponsive during ordinary conversation and behaving as though he were receiving messages from somewhere else. It was like watching Cal's collapse happen again.

"Understanding the pattern," Pete repeated in an almost singsong voice. "Accepting the invitation."

He turned from the wall. The calm, peaceful expression on his face disturbed me more than panic would have done. He did not look like a man who believed he was suffering a breakdown. He looked like a man who believed he had found the truth.

"Soon," he said with absolute certainty. "Very soon."

Later that morning, on the third day, I woke to rotor blades beating through the air. The noise jolted me upright from where I had slumped against the medical bay wall. My neck ached from the awkward position. Imran was already at the window, his face pressed against the glass and wearing an expression I had not seen in days.

Hope.

"Helicopter," he said, his voice cracking. "It's actually a helicopter."

I scrambled to my feet, my joints protesting after three days in cramped quarters with almost no proper rest. Through the window I saw the aircraft approaching from the south-east, a black speck against the grey morning sky that grew with each second.

"Thank God," I breathed as I joined him. "Someone has finally come for us."

As it approached, I saw that it was an unmarked government-operated transport helicopter. It was neither an HM Coastguard aircraft nor a civilian offshore helicopter, and it bore no insignia identifying the organisation operating it. Rotor wash struck the sea around Morrow, breaking the unnatural stillness into widening ripples.

"They aren't slowing down," Imran said, his hope giving way to confusion.

He was right. The helicopter continued at the same speed instead of preparing to land. It passed low over the platform, and someone in the open doorway pushed out a waterproof package. A small parachute deployed immediately.

The package struck the deck, bounced once and came to rest near the central equipment housing. The helicopter then turned sharply and flew away.

"Wait!" Imran shouted after it. "Come back! We need to be taken off!"

The aircraft dwindled into the distance, leaving us with the package and a dreadful sense that a straightforward rescue had never been intended.

We dismantled enough of our barricade to squeeze through the medical bay door, then approached the package cautiously. It was a waterproof transport container without identifying marks, apart from a small geometric logo that resembled one of Pete's symbols.

Inside lay a single sheet of official headed paper and a smaller sealed envelope. The same geometric logo appeared at the top of the letter, above the name Centre for Cognitive Hazard Research and Containment.

Imran snatched up the letter and read aloud, his disbelief deepening with every sentence.

"To the remaining personnel aboard Morrow platform. Your crew has been exposed to a cognitive hazard requiring specialised extraction protocols. Standard rescue procedures are ineffective and potentially dangerous. The following instructions must be followed precisely to ensure successful separation from the anomaly."

He stopped and stared at me.

"This is insane. A cognitive hazard? What does that even mean?"

I took the letter and continued. The instructions were beyond bizarre.

First, we were to memorise a phonetic counter-sequence contained in the sealed envelope. The letter described it as a language-neutral cognitive buffer. Second, precisely at 00:00, we were to burn every item of written material connected with the anomaly, specifically including Cal's note and the Centre's own instructions. Immediately afterwards, while standing on the platform's central structure, we were to recite the memorised counter-sequence in full.

The letter ended with a warning that chilled me.

"Failure to follow these procedures precisely will result in permanent cognitive integration with the anomaly. The extraction window closes at 00:30. No further assistance will be provided."

"It's elaborate nonsense," Imran said when I had finished. "Cognitive hazards, language-neutral buffers, cognitive integration. It's meaningless jargon meant to convince us that there is some scientific explanation for this."

I wanted to agree, but the helicopter's behaviour troubled me. A conventional rescue crew would have landed and taken us off first, leaving questions until later. Instead, someone had gone to considerable trouble to deliver precise instructions while keeping clear of the platform.

"Perhaps," I said. "But an organisation capable of deploying an unmarked helicopter believes these procedures are necessary. That suggests they know something we don't."

"Or they're part of whatever has been done to us. Think about it. A mysterious organisation appears with bizarre instructions at the precise moment we're most desperate. That's manipulation."

I opened the sealed envelope. Inside was a single page of text that was plainly not English. The written forms resembled Pete's drawings but had been arranged into structured lines. Beneath them was a phonetic transcription that allowed the sequence to be spoken without understanding its meaning.

"This is what we're supposed to memorise," I said, showing it to Imran.

He glanced at the page and shook his head.

"I'm not taking part in this. Whatever game they're playing, I refuse. We should concentrate on real solutions: repair the radio, signal for proper help, find some way off the platform ourselves. If the Centre genuinely knows how to save us, it can land and extract us like human beings. I'm not performing rituals for people who won't even identify themselves properly."

I studied the transcription and tried silently to form the unfamiliar syllables. They felt wrong even in my imagination, as though my tongue had not been designed to make those sounds.

"Pete," I called. "Pete, come and look at this."

He did not answer. He remained at the table, tracing patterns over his drawings. When I moved closer, I saw his lips moving continuously. He was whispering the same strange syllables printed beneath the counter-sequence.

"He's already reciting it," I said. "However he learnt it, Pete already knows whatever language this is."

Imran joined me beside the table and looked down at him with open concern.

"Pete, can you hear us? Do you understand what's happening?"

Pete looked up briefly, his eyes struggling to focus on us. When he spoke, English mingled with the strange syllables.

"Integration proceeding. Optimal synchronisation. Barriers dissolving."

Then he returned to his whispering and the tracing of patterns, completely detached from our conversation.

"He's gone," Imran said flatly. "Whatever process took Graham and Cal has claimed Pete as well. His body is still here, but his mind is somewhere else."

The sight of him disturbed me profoundly. Pete was in a worse state than Cal had been before vanishing, yet somehow he remained physically present, oblivious to everything around him.

I spent the rest of the day memorising the phonetic counter-sequence, despite Imran's repeated warnings. The transcription made it possible, but the sounds left me increasingly uneasy each time I practised them.

We also searched every accessible section of the platform again. We found no sign of Graham or Cal. The covered corpse in the obsolete orange survival suit remained locked inside the secured external recovery area, its repeated parallel wounds still offering no clue to its identity.

By evening I could recite the entire sequence without consulting the page, although I still had no idea what it meant.

Imran made one final attempt to repair the radio, carefully disassembling cables and circuit boards, but the damage was too extensive and too systematic. Graham, Cal or whoever had controlled them had done the job thoroughly. By sunset, Imran finally gave up.

"Even if I managed to transmit," he said, "who would receive it? The Centre is clearly monitoring the platform. They would probably intercept anything we sent."

As midnight approached, the platform's groans intensified. The vibrations became rhythmic, almost musical, as though the whole structure were resonating with an external force.

Through the medical bay window I watched the sea change. Dark shapes moved beneath the surface, more numerous and far larger than anything Cal had described. Light pulsed through the water, forming patterns that spread out from Morrow in every direction. The luminous areas arranged themselves into geometric designs horribly reminiscent of Pete's symbols.

"It's beginning," I said as the display intensified. "Whatever the Centre warned us about, it's happening now."

Imran joined me at the window, his face pale.

"Those patterns aren't random, are they?"

"No. They're organised. Deliberate."

I checked my watch. It was 23:47. Thirteen minutes remained until midnight.

"You're really going to do this?" Imran asked. "You're going to follow their instructions?"

I looked at Pete, still hunched over the table he had covered in symbols, and thought of Graham and Cal, who had vanished without any chance of rescue. The Centre's letter might have been another act of manipulation, but it was the only contact we had received since the crisis began.

"I don't see another choice. Pete is already lost, and we're running out of time. If there is even a chance this works, I have to try."

Imran stood silently for a while, watching the glowing patterns beneath the sea.

"If you're doing it, I'm not leaving you alone out there. I won't recite the sequence, but I'll watch you. I'll make certain nothing happens to you."

At 23:58, I gathered Cal's note, the Centre's letter, the page containing the counter-sequence and every sheet Pete had covered with anomalous symbols. I also took a lighter from the medical bay's emergency kit. We could not remove all the marks Pete had drawn directly onto the walls, but we carried every loose written item connected with the anomaly.

Pete followed without seeming to understand where we were going. He walked like a sleepwalker as we made our way to the platform's central structure.

The light beneath the sea had become dazzling. It pulsed in time with the platform's vibrations, and from our elevated position we could see the designs spreading across the water. They seemed to convey information in a form my mind could not interpret.

Precisely at 00:00, I set fire to Cal's note, the Centre's instructions, the phonetic sheet and Pete's symbol-covered pages. The papers caught quickly. Bright orange flames consumed Cal's desperate words and the impossible markings. As the last scraps blackened and collapsed into ash, the luminous patterns below abruptly changed, assembling themselves into new configurations.

"Euan," Imran called from the medical bay doorway, where he had remained to watch. "Something is changing."

I began reciting the memorised counter-sequence, concentrating on forming every unfamiliar syllable correctly. The sounds felt unnatural when spoken aloud.

Pete stood beside the burning remains of the papers. His lips moved in perfect time with mine. As we spoke, the light in the sea intensified until it spilled across the platform deck.

The creaking structure began to sound almost musical, each resonance aligning with the counter-sequence. It was longer than it had seemed while I memorised it. Sections repeated and accumulated, each phrase building upon the one before. Pete recited beside me with increasing certainty, as though he understood what I could only reproduce.

As we neared the end, the platform convulsed. For one terrible moment I thought the whole installation would collapse into the luminous sea. Then the movement settled into a steady beat matching the final words.

I spoke the last syllable.

Silence fell.

Every groan and vibration ceased. The light beneath the sea began to fade, and even the ordinary wind and machinery seemed hushed. Pete stood with his eyes closed, peaceful for the first time in days. Imran remained in the medical bay doorway, watching the water darken.

"Is that it?" he called. "Is it over?"

I had no answer. The Centre's instructions had not explained what would follow the recitation, only that everything had to be completed before the extraction window closed at 00:30. We had finished with nearly twenty minutes remaining.

The light vanished entirely, leaving ordinary black water beneath a starless sky. Whatever had moved below was no longer visible. I could not tell whether it had gone or had simply stopped revealing itself.

Pete opened his eyes and looked directly at me. For the first time since his deterioration began, his expression held complete clarity.

"Thank you," he said in perfect English. "The transition is complete."

He turned and walked calmly towards the seaward rail.

For half a second, I did not understand what he intended. Then he climbed over the safety barrier and stepped into the darkness.

I lunged after him, but the sudden loss of the sea's glare had ruined my night vision. Equipment and structural braces lay between us, and I could not reach the rail safely before he fell. I heard the splash below but could see nothing in the black water.

"What happened?" Imran shouted from the doorway. "Where did it all go?"

I could not answer. My mind still reeled from the counter-sequence and the abrupt shift from impossible light to ordinary darkness. Had the procedure worked? Were we safe? The Centre had told us only to finish before 00:30.

Pete was gone. He had declared the transition complete and stepped over the rail as calmly as a man entering another room. The sea concealed whatever awaited beneath it.

The platform's unnatural mechanical groaning had stopped. Only the normal hum of electrical systems and the slap of waves against the supports remained. After days of impossible phenomena, those ordinary sounds felt alien.

Then another sound broke the quiet: rotor blades approaching from the south-east, much closer than before and growing louder by the second.

"Another helicopter," Imran called, moving for a clearer view through the medical bay window. "This one is coming in quickly."

I saw its navigation lights, red and white points advancing towards the platform. Unlike the aircraft that had delivered the package, this one slowed and descended in a clear approach.

A searchlight swept across Morrow as the helicopter crossed the platform's edge. It was a large, unmarked government-operated transport aircraft. Its cargo door stood open, revealing several people in bulky protective clothing. The rotor wash was so violent that I had to seize a support post to remain upright.

Rather than landing on the helideck, the aircraft hovered above the central structure. Thick ropes dropped from the cargo bay, and four figures descended at once. They wore sealed chemical-protection suits with full-face respirators and carried equipment I did not recognise.

"Step away from the structure," one ordered through an external speaker. "Proceed to the designated extraction point."

I backed away with my hands raised to show that I posed no threat. Their movements were disciplined and practised, and their equipment suggested they considered Morrow dangerously contaminated.

Imran emerged from the medical bay with his hands raised as well.

"We're the survivors," he said. "We need to be taken off and given medical treatment."

"Affirmative. Extraction protocol is in effect."

The lead figure approached him with an injector.

"This is a precautionary sedative. You will remain unconscious during transport."

"Wait," I said, moving towards them. "We need to tell you what happened. There were five of us aboard originally, and the other men are missing. The body in the secured recovery area is still-"

The injector struck my neck before I could finish. Whatever it delivered acted almost instantly. Drowsiness swept through me and my muscles lost their strength. My vision blurred. I struggled to remain standing.

"Standard procedure," the suited figure said as I sagged. "Cognitive contamination requires controlled extraction."

Imran received an injection moments later. Even as the sedative took hold, he tried to report the missing crew, the sabotage and the covered corpse outside. The team showed no interest in our account.

They worked with mechanical efficiency, securing us to wheeled stretchers lowered from the helicopter. Other members moved through the platform to conduct a rapid search. Their later record would state that Graham, Cal and Pete were missing, and that the unidentified corpse had vanished from the locked external recovery area during the final blackout.

Within minutes, Imran and I were being winched into the cargo hold.

I drifted in and out of consciousness during the ascent, catching fragments of radio traffic between the extraction team and its base. The voices were clinical and detached. They discussed us as contaminated material rather than rescued men.

"Containment secured. Two subjects sedated for transport."

"Estimated arrival at Containment Site C in thirty minutes."

"Understood. Medical team standing by for decontamination. Memory-suppression protocols prepared."

"Platform exhibits no remaining active manifestation. Three crew unaccounted for. External recovery subject also missing. Recommend standard containment clean-up."

The helicopter banked as it gained height. Through a small window, I saw Morrow platform for the last time. It appeared completely ordinary, standing alone in the dark North Sea. There were no glowing patterns and no visible sign of what we had witnessed.

Strapped to the stretcher with Imran secured on the only other one beside me, I wondered whether any of it had happened. The drugs pulled me deeper into sleep as the flight dissolved into disconnected impressions: the hammer of the rotors, subdued voices, the smell of disinfectant and stale air inside the sealed cargo compartment.

When I surfaced briefly, we were landing at a brightly illuminated facility that was not Aberdeen International Airport. Plain institutional buildings enclosed the landing pad, resembling a research complex. Hard white lights made the place look cold and official.

Medical staff met the aircraft and transferred Imran and me onto trolleys and wheeled stretchers. I tried to ask where they were taking us, but my words emerged as an incoherent murmur. The drugs left me conscious enough to see, but too heavily sedated to speak properly.

We were separated as soon as we entered the main building. Imran disappeared down one corridor while they wheeled me into an examination room. It was windowless and clinically spotless, fitted with unfamiliar monitoring equipment and ceiling-mounted cameras.

A doctor in theatre scrubs approached my trolley, consulting a tablet as she examined me.

"Subject displays expected symptoms of cognitive contamination. Blood tests will establish exposure levels. Begin the standard decontamination sequence."

"What sort of contamination?" I managed to ask, scarcely above a whisper.

She ignored the question and nodded to a nurse carrying another injector.

"Subject remains verbally responsive. Increase sedation for blood-draw procedures."

The second injection entered my arm. This dose was stronger. My vision narrowed to a tunnel, and remaining conscious became nearly impossible. I heard the medical team discussing tests and treatment protocols, but their voices seemed to come from an immense distance.

When I woke again, I was in another room, lying in a hospital bed within what appeared to be a secure specialist NHS-adjacent clinical unit operated under an undisclosed government contract. Several intravenous lines ran into my arms, and monitors beeped steadily beside me.

A narrow window admitted daylight, although it looked only onto another wing of the complex. A different doctor sat beside the bed, writing on a clipboard. She looked up when she realised I was awake and gave me a professional smile that did not reach her eyes.

"Good morning, Euan," said Dr Eleanor Vane.

"I'm Dr Eleanor Vane. You've been unconscious for approximately eighteen hours while we carried out the necessary medical procedures. How are you feeling?"

My mouth was dry, and my thoughts felt sluggish and disconnected.

"Where am I? What happened to Imran and Pete?"

"You're in a secure specialist clinical unit outside Aberdeen. You've been through a significant traumatic experience, and we're here to help you recover."

Dr Vane consulted her clipboard. "Your blood tests show evidence of severe psychological stress and possible exposure to hallucinogenic compounds. That would explain the vivid episodes you experienced on the platform."

"Hallucinogenic compounds? That's not what happened. We were isolated on Morrow for days. The others disappeared one by one, and there was something in the water."

"Euan, I need you to listen carefully." Dr Vane's voice became patient but firm. "According to our investigation, you were alone on Morrow platform for nearly three weeks. The isolation and stress caused severe psychological symptoms, including hallucinations and paranoid delusions."

The words struck like a physical blow.

"That isn't true. Graham was our foreman. Cal saw something in the water. Imran helped me search after they disappeared. Pete was drawing symbols all over the medical bay."

"There is no record of those individuals being assigned to Morrow during your deployment. Our psychiatric assessment suggests that you created these identities to cope with the isolation."

Dr Vane added another note to her clipboard. "This can occur in cases of extreme social deprivation."

I tried to sit up, but the intravenous lines and monitoring leads restricted me. "Check the crew manifest. Check the employment records. Those men were real. They weren't hallucinations."

"We have conducted a thorough investigation. The employment records show that you were the only person assigned to the installation during the relevant period. Your supervisor confirms that it was a special assignment requiring prolonged solo monitoring of automated systems."

The certainty in her voice made me question my memories for the first time since the ordeal began. The sedative, and whatever else they had put into me, made clear thought almost impossible. Yet I knew that Graham Hargreaves, Cal Strachan, Imran Qureshi and Pete Walsh had been real.

"What about the helicopter that delivered the Centre's instructions? What about the extraction team in sealed chemical-protection suits?"

Dr Vane turned to another page. "You activated the platform's emergency beacon and were collected alone by an HM Coastguard aircraft. There were no chemical-protection suits and no special instructions. It was an ordinary emergency evacuation prompted by your deteriorating mental state."

Nothing she said matched my memories. Yet each dose made exact details harder to hold. The more fiercely I tried to recall what had happened, the faster it dissolved.

Over the following days, the clinical staff subjected me to repeated psychological assessments, asking detailed questions about my time aboard Morrow and recording every answer. Each session left me less certain of what had happened. They spoke of reality distortion and trauma-induced psychosis, reducing everything I remembered to the symptoms of a breakdown.

They prescribed medicine for anxiety and sleep, but it interfered with my memory as well. Graham and the others became less distinct. Whenever I reached for a conversation or a particular expression, it seemed insubstantial, like a scene remembered from a film.

"This is a normal part of recovery," Dr Vane explained during one session. "As your brain processes the trauma in a healthier way, the defensive fantasies will naturally dissolve. You'll remember the isolation and stress without the elaborate hallucinations your mind created to protect you."

"They weren't hallucinations," I insisted, though there was less conviction in my voice. "I remember Cal's note. I remember the symbols Pete drew. Those details were too specific to be imaginary."

"The human brain is remarkably creative under extreme stress. It can produce detailed false memories which feel entirely real." Her pen scratched constantly across the paper. "Your case is clinically fascinating. The consistency and complexity of the personalities you created suggest exceptional psychological resilience."

As the days passed, I began questioning things I had known only hours before. Had Graham really been so tall? Had Cal's handwriting looked as frantic as I remembered? The more precisely the clinicians asked me to describe them, the more the details blurred and shifted.

When I mentioned the strange syllables in Cal's note and the Centre's phonetic counter-sequence, Dr Vane showed particular interest.

"Can you reproduce any of the sounds, even approximately?"

I tried to recite the sequence I had memorised so carefully, but it was gone. Syllables that had once felt charged with meaning now produced only shapeless noises.

"Fascinating," Dr Vane murmured as she filled another page. "The brain's capacity to create and then discard intricate false memories is quite remarkable."

"I didn't invent this. Something real happened on that platform. Something that required a specialist extraction."

"I want you to consider the possibility that your mind created an elaborate scenario to protect you from a simpler but equally traumatic truth. Nearly three weeks of complete isolation on an offshore installation would be psychologically devastating. Your brain may have populated that environment with companions to prevent a total collapse."

It made a horrible kind of sense, especially through the fog of the medication. Still, some part of me refused to accept that Graham, Cal, Imran and Pete had sprung fully formed from my imagination. They had been too real and too different from one another.

"What condition was I in when I was found? Was I injured? Malnourished? Dehydrated?"

"You were severely exhausted and malnourished, consistent with somebody struggling to maintain basic self-care during a psychological crisis. You had no injuries that could not be explained by ordinary platform hazards."

Every conversation confused me further. The staff appeared concerned for my welfare, but their constant insistence that my memories were false felt like another form of pressure. Under the medication, I could no longer distinguish what I had experienced from what stress might have invented.

When I asked to speak to Imran, so that he could confirm what we had seen, Dr Vane looked genuinely puzzled.

"Euan, there was nobody called Imran on the platform. We've discussed this several times. You were alone throughout the entire period."

"Then who was extracted with me? There was another wheeled stretcher in the helicopter. Imran was on it."

"You were the only patient transported. You may be combining memories from other sources, perhaps films or books about rescue operations."

Her certainty, reinforced by the lingering drugs, made me doubt my own senses. If there was no record of Imran or Pete being extracted, perhaps they truly had been creations of an isolated mind.

But when I asked to see the aircraft's flight record or speak to the HM Coastguard crew she claimed had rescued me, Dr Vane dismissed the request with references to patient confidentiality and an ongoing investigation.

"Your priority must be recovery, not the reconstruction of traumatic memories. The more you analyse these experiences, the more distressing they will become."

She changed my dosage again. After that, asking questions became much harder. The tablets left me detached and compliant, more inclined to watch television or sleep than to examine anything uncomfortable.

Days merged into one another through examinations, assessments and altered prescriptions. I stopped asking about Imran and Pete. I stopped insisting that Graham and Cal had existed. Dr Vane praised my progress and said my delusional fixations were diminishing as my mind processed the trauma.

Yet late at night, when the medicine weakened slightly, memories returned with a specificity no fantasy should have possessed: Cal's terrified face as he described the shapes below the water; Pete whispering painful syllables while tracing symbols in the air; the cleanly severed radio cables; the sabotaged telemetry and emergency beacon that had prevented any genuine alarm from reaching shore.

Whenever I told Dr Vane about these persistent images, she increased the dosage until I stopped mentioning them.

At last, I signed my discharge papers. Dr Vane sat opposite me with her usual professional smile and explained that compensation had been paid directly into my bank account.

"Offshore work carries inherent psychological risks," she said, sliding a payment advice slip across the polished desk. "Firth Energy Services recognises your traumatic experience and wishes to ensure that your return to ordinary life proceeds smoothly."

GBP31,500. More than I would earn in a year offshore. It seemed calculated to discourage questions rather than compensate me.

I folded the documents and put them inside my jacket. The official headed paper identified the place only as the Aberdeen Clinical Assessment Centre. Nothing stated that it was a secure specialist NHS-adjacent unit operating under an undisclosed government contract.

"My memory is still foggy. The timeline doesn't feel right. Nearly three weeks alone doesn't match what I remember."

Dr Vane glanced at her clipboard. "Memory distortion is entirely normal after psychological trauma. Your brain is protecting itself by suppressing the most distressing elements. Fighting those defences will only delay your recovery."

She handed me a bottle of prescribed tablets. The label bore my name and the name of a drug I had never encountered.

"Continue taking these for six months. You'll attend an occupational and psychological assessment at the end of every month. Provided you remain stable, the dose will be reduced in small stages at each appointment. If you experience vivid dreams, memory gaps, intrusive thoughts or any recurrence of your former symptoms, contact us immediately."

The van journey back to Aberdeen took forty minutes through countryside I did not recognise. The driver ignored my attempts at conversation and followed roads which seemed to loop unnecessarily before reaching the familiar streets near the harbour. Outside my block of flats, he merely nodded and waited while I collected my weatherproof kit holdall.

My flat looked exactly as I had left it, though I could not remember when that had been. Post lay heaped on the kitchen worktop: bills, advertising leaflets and letters from friends who had apparently been told that I was recovering from a work-related accident. The postmarks suggested I had been away for nearly a month, which was at least consistent with Dr Vane's claim that I had spent almost three weeks alone before my treatment began.

I spent the afternoon searching my belongings for anything that might restore a clearer account of events. My work logs contained ordinary entries until 15 March 2026, then stopped. The final entry recorded my assignment to Morrow platform for routine maintenance, but I could not connect it to any stable memory.

In a desk drawer I found a small notebook I did not remember keeping. Its pages contained notes on offshore assignments, weather and crew rotas, all in my handwriting, but covering periods which did not agree with my employment record.

One entry read, "Graham worried about equipment failures."

Another said, "Cal acting strangely after morning watch."

Reading them felt like opening somebody else's diary.

The medicine made sustained concentration difficult, but images surfaced without warning: black water, metal groaning under strain and voices shaping syllables that hurt whenever I approached their meaning. Each memory vanished before I could examine it, leaving only a sense of unfinished business.

Sleep brought more persistent visions. Luminous patterns spread across dark water while enormous shapes pulsed beneath them. Sometimes voices called from far below, not human but somehow familiar. I woke with salt on my tongue, convinced that somebody had tried to tell me something important.

By my third week back in Aberdeen, solitude had become unbearable. Each morning I walked to the harbour and stared across the North Sea, feeling that I had abandoned something out there.

The Assessment Centre had given me details of counselling services, but talking about my "adjustment difficulties" was pointless when the counsellor treated every memory as a stress-induced fantasy. Instead, I rang my supervisor at Firth Energy Services.

"Euan, good to hear from you, mate. How are you feeling?"

Alistair Fraser's voice held genuine concern and unmistakable relief.

"I'm ready to return to work. The doctors say keeping active will help."

There was a pause. "Are you sure? After what you went through out there, perhaps you should take longer."

"What I went through?"

The way Ali had said it suggested he knew more than the medical account revealed. When I pressed him, he became evasive.

"Company policy is to leave those discussions to the clinicians. All I know is that you had a difficult time on a solo assignment and required specialist treatment."

Solo assignment. The phrase disturbed me, although I could not explain why.

"I need to work, Ali. Sitting here thinking about it isn't helping."

He arranged a physical examination and an occupational psychological assessment for the following week. The company doctor spent less than an hour reviewing my records before clearing me for light duties. The psychological assessment was more thorough, but concentrated entirely on my tolerance of isolation and stress rather than the facts of my previous assignment.

"Any recurring dreams or intrusive thoughts?" the assessor asked.

I had learnt to be careful. "Some anxiety about returning to work. Normal recovery symptoms."

"Good. The Assessment Centre says you've responded well to treatment. We'll put you on day shifts at first. Nothing too demanding."

Two weeks later, I was aboard a helicopter heading over the North Sea. The familiar routine of safety checks and loading kit reassured me, although the other technicians kept a subtle distance. News travelled quickly offshore, and my breakdown was evidently common knowledge.

The assignment involved straightforward maintenance on a platform about forty-five kilometres north-east of Aberdeen. It had a smaller crew, a shorter rota and none of the isolation factors supposed to have caused my illness.

The work was routine enough to perform automatically while my mind wandered towards less manageable questions. My colleagues remained professional but avoided discussing my absence. When somebody mentioned Morrow over lunch, the conversation shifted at once after several glances in my direction.

Later, I asked a veteran technician what he knew about the installation.

"Morrow?" He looked genuinely confused. "Haven't heard that designation in years. It was decommissioned and dismantled in 2009. Nothing's operated at that site since."

"I was working there in March."

"Perhaps you're thinking of Brae Point or Morven Ridge. They're both active in the northern fields."

Back ashore, I searched the company database. Public records confirmed that Morrow had been decommissioned and dismantled in 2009. Nothing had operated at its former location since then.

My employment history nevertheless showed an assignment there beginning in March 2026.

When I raised the discrepancy with Ali, he seemed as perplexed as I was.

"Must be a clerical error. Old records get tangled sometimes. I'll have somebody correct it."

No correction appeared. Whenever I checked, the impossible assignment remained: a deliberate-looking entry placing me aboard an installation dismantled seventeen years earlier.

The tablets were meant to help me sleep, but instead they left me detached from daily life. I found myself standing on street corners without knowing how I had arrived, or sitting in restaurants before half-eaten meals I could not remember ordering. One evening my keys turned up in the fridge and a bag of shopping on my desk.

My colleagues noticed my distraction. I would begin speaking and lose the thread halfway through, or stand motionless for minutes before equipment I was meant to inspect.

At my first monthly occupational review, Ali raised the matter gently.

"You're competent, Euan, but you seem elsewhere. As if your mind is working on something you can't quite reach. Perhaps you need additional counselling."

His observation was more accurate than he knew. Every day I felt that something essential was slipping just beyond recall. Names, faces and conversations dissolved whenever I tried to hold them.

I began carrying a pocket notebook, recording where I went, whom I spoke to and anything significant I thought or felt. Each evening I wrote down everything I could remember, hoping to bridge the unexplained gaps.

After two weeks, I discovered entries in my own handwriting which I had no memory of making.

"Walked to harbour at 03:00. Watched the water for two hours. Nothing visible tonight."

"Rang Aberdeen Clinical Assessment Centre. Hung up when Dr Vane answered."

"Researched offshore disappearances. Found seventeen cases resembling mine since 2008."

The notes were detailed and precise, yet they read like somebody else's private thoughts. According to my handwriting, I had investigated missing offshore workers, government concealment and cognitive anomalies among isolated groups.

The most disturbing entry occupied a whole page in careful block capitals.

"They know I'm remembering. The medicine isn't working any more. Graham, Cal, Imran and Pete were real. The Centre is monitoring my recovery. I must stop writing before they notice."

Beneath it were symbols composed of nested angles, broken rings and repeating parallel strokes. Looking directly at them made my eyes ache. In my peripheral vision they appeared to rearrange themselves.

It was my notebook, my pen and unmistakably my handwriting, but I had no recollection of creating any of it.

I shut the book and placed it in the desk drawer beside the prescription bottle I had then been taking for three months. The white tablets rattled when I shook it. For the first time since my discharge, I wondered whether my recovery was proceeding according to my needs or somebody else's design.

The six-month programme continued with mechanical regularity. At the end of each month I attended an occupational assessment and a separate appointment with Dr Vane. After the first appointment she reduced the evening dose slightly. The second reduction followed at the end of month two, and another at month three despite my worsening gaps. Months four and five brought further small reductions, each accompanied by questions about dreams, salt water, repeated sounds and any urge to investigate Morrow. At the sixth assessment, she lowered the dose to what she called a maintenance level and renewed the prescription indefinitely.

Throughout those months I continued working offshore under supervision.

One night I dreamed of voices calling from deep water, repeating names I almost recognised.

I found the envelope beneath the door of my flat after returning from a two-week rota on Fulmar platform. It was plain white, with no return address. My name had been written in block capitals that looked traced rather than natural.

Six months had passed since my discharge from the Aberdeen Clinical Assessment Centre: six months of routine assignments, monthly occupational and psychological assessments, scheduled dosage reductions and memory gaps that grew wider rather than narrower. The notebook remained my only reliable record, although I had stopped examining it after finding the entries I could not remember writing.

My flat felt different. Nothing had visibly changed, yet it no longer seemed entirely mine. I opened cupboards expecting objects that were not there and stood in rooms unable to recall why I had entered them.

The envelope lay on the kitchen table while I made strong tea in my battered insulated mug. The routine anchored me: water to the marked line, one teabag, four minutes to brew. Simple, measurable actions that left me able to approach something more difficult.

When I opened the envelope, I recognised the geometric logo from the extraction instructions. The message beneath it was printed on the same official headed paper. It was brief, clinical and devastating.

"Mr Mercer,

"Our monitoring indicates that you have attempted to reconstruct memories altered for your psychological protection. Such efforts are counterproductive to rehabilitation and may cause permanent cognitive damage."

I read the words twice.

Monitoring. They had watched me while I tried to understand Morrow. They knew about the dreams, the unremembered notebook entries and the persistent sense that something had been taken from me.

The letter continued in the same cold register Dr Vane used.

"Your condition resulted from exposure to a cognitive anomaly operating outside ordinary perceptual reality. Conventional psychiatric treatment proved ineffective. Controlled alteration of autobiographical memory was therefore necessary to prevent irreversible psychological collapse.

"Your memories were modified to preserve essential cognitive functions while removing information hazardous to conscious processing. This intervention has enabled you to retain employment and social function that would otherwise have been impossible."

A cognitive anomaly. Not hallucinations, not stress, but something real enough to measure and contain. Whatever we had encountered required an organisation with resources and authority far beyond an ordinary hospital.

I put down the letter and went to the window. Aberdeen Harbour lay below, supply vessels travelling between shore and the platforms beyond the horizon. It was the same movement I had watched for years, but now it resembled somebody else's life playing silently on a screen.

How much of my return was my choice? How much had been managed?

The next paragraph answered me.

"Controlled exposure to maritime and offshore environments reinforces the revised memory structure while reducing the likelihood of reversion to the original traumatic state. Your supervisors are aware of your condition and have been instructed to monitor your adjustment."

Ali's careful choice of assignments, my colleagues' distance and the evaluations focused on isolation had all been arranged by people who knew precisely what had happened. Even the false employment entry placing me on Morrow might have been planted as part of the treatment, or left behind as an artefact of whatever system contained the truth.

The final paragraph made my hands shake.

"Although your memories were modified for your protection, the Centre considers limited disclosure necessary to discourage further investigation. Graham Hargreaves, Callum Strachan and Peter Walsh remain cognitively integrated with the anomaly. They retain awareness of their condition and of the events preceding their transition. Imran Qureshi survived extraction, but cannot be safely released. He remains conscious under permanent secure containment at Containment Site C."

Their names struck through the fog.

Graham. Cal. Pete. Imran.

Their faces almost returned: Graham's authority strained by fear, Cal hunched over his half-finished sudoku book, Imran beside me in the helicopter on the other wheeled stretcher, Pete staring towards the water as though something below had taught him how to see.

They had not been invented. They had endured the platform with me. Graham, Cal and Pete remained joined to whatever had waited beneath Morrow, lucid inside altered states beyond ordinary human experience. Imran had escaped the platform alive, only to spend the rest of his life awake in a secure cell.

I had been given forgetfulness. They had been given no such mercy.

The letter ended with instructions and a threat.

"Burn this communication immediately after reading. Continue the prescribed medication schedule and all assigned offshore duties. Do not investigate your former colleagues, Morrow platform or your suppressed memories. Further attempts will activate protective protocols and may require more invasive treatment."

I read the message again, trying to memorise details that my altered mind might reject within hours. Then I carried it to the kitchen sink and held a lighter to one corner.

The threat made the choice for me. I wanted evidence, but I knew what "more invasive treatment" meant.

The flame consumed the headed paper, taking the names and the confession with it. I crushed the ashes and washed them down the drain until no physical trace remained.

For the moment, the truth survived in my head. The Centre for Cognitive Hazard Research and Containment existed. My memories had been deliberately altered. Graham, Cal and Pete remained conscious within the anomaly. Imran remained conscious in permanent confinement.

I stepped on to the balcony and stood at the rail, looking across Aberdeen Harbour towards the North Sea. Platforms marked the horizon beyond the supply vessels. Somewhere out there, perhaps beneath an installation that officially did not exist, three men continued to experience what had happened to them. Elsewhere, behind sealed doors, Imran remembered it all alone.

My notebook lay open on the table behind me, filled with daily records of a life I could not always recall living. The following morning I would report for another offshore assignment. I would continue the routine designed to keep me stable, and the maintenance dose would make it harder to question the gaps. Solitary duties would limit the friendships that might disrupt the revised memories.

Standing in the salt air as supply vessels moved towards platforms where I might one day work, I understood that I would never be permitted to recover the whole truth. The reality beneath it was too dangerous for an unaltered human mind.

They had offered partial forgetting as a gift and left me with fragments of a story too terrible to hold. Harbour lights trembled across the black water stretching towards the horizon, while beneath the North Sea the anomaly persisted, and the men it had taken remained awake.
