The Hungry Water

I had been living in my parents' converted cellar for three months, two weeks and four days. Not that I was counting. The narrow window near the ceiling admitted just enough daylight to remind me that the world was still turning outside while I remained trapped in a cycle of rejection emails and mounting debt. My laptop glowed with yet another standard refusal.

"Thank you for your interest in our engineering vacancy. After careful consideration, we have decided to pursue other candidates whose qualifications more closely match our requirements."

I closed the laptop harder than necessary. A four-year integrated master's course in engineering at a respectable British university had earned me precisely nothing, except the privilege of sleeping on a sofa-bed in my childhood home and avoiding my mother's worried glances. I had accumulated about GBP 18,000 in overdraft, credit-card and postgraduate debt, and the first immediate repayments were already due.

"Daniel?" Mum called from the top of the stairs. "Are you awake?"

"Yeah," I called back, my voice still rough with sleep despite it being past noon.

The stairs creaked as she came down, carrying a mug of tea in one hand and a printed sheet in the other. My mother, Margaret Chen, had the peculiar ability to look worried and hopeful at the same time. I had seen that expression increasingly often since moving home.

"I brought you some tea," she said, setting the mug on the little table beside the sofa-bed. "And I found something you might want to look at."

She handed me the page. It was a job advert headed: "Technical Assistant - Gannet Island Marine Observatory."

"Marine research?" I asked, scanning the details. "Mum, I'm an engineer, not a marine biologist."

"Keep reading," she urged, sitting on the edge of the bed. "They need someone with engineering skills to maintain instruments and help collect data. Accommodation and meals are included, and the salary is decent."

The advert described a six-month technical contract at a remote island observatory several hundred nautical miles west of the Outer Hebrides. The work involved cold-water reef monitoring and marine-instrument maintenance. The requirements included mechanical aptitude, basic programming knowledge and a willingness to live in an isolated environment. I could honestly claim all three.

"I don't know," I said, although I kept reading with growing interest. "Gannet Island? I've never heard of it."

"It's a small, privately funded observatory," Mum said. "I looked it up after I found the advert. They monitor cold-water reefs, currents and that sort of thing. The important part is that they need your skills and they're offering good money."

I sipped my tea and considered it. Six months on a remote North Atlantic island sounded extreme, but my alternatives were non-existent. My savings had dwindled to almost nothing, and creditors were already asking when I intended to start paying them.

"You think I should apply?" I asked, already knowing the answer.

"I think you need a fresh start," she said carefully. "And perhaps some time away from everything would help you work out what comes next."

By everything, she meant my spectacular failure after university: the relationship that had imploded, the dream jobs that had never materialised and the depression that kept me asleep until noon most days.

"The deadline is today," she added, tapping the paper. "I'd say it's worth a try."

Three hours later, I submitted the application with a hastily updated CV and a covering letter that tried to sound enthusiastic about marine research without revealing my complete lack of relevant experience. To my surprise, a reply arrived that evening requesting a video interview the following morning.

The interview lasted barely fifteen minutes. It was conducted by a stern-faced woman named Dr Helen Ward, who seemed far more interested in my ability to tolerate isolation than in my technical qualifications.

"The observatory is extremely remote, Mr Chen," she said, her intense green eyes studying me through the screen. "The passage from Oban takes four days in normal conditions because of the distance, weather and a scheduled supply stop. We receive a supply run every five weeks, weather permitting. Are you comfortable with that?"

"Absolutely," I lied, wondering what I was getting myself into.

"Very well," she said after a short pause. "The post is yours if you want it. We need someone immediately. Can you be ready to leave in three days?"

I blinked, stunned by the speed of the offer.

"Yes. I can do that."

"Excellent. Travel instructions will follow shortly. Pack lightly but sensibly. The island has a cold maritime climate and the weather can change without warning."

And just like that, I had a job.

The next three days passed in a blur of hurried preparation. My parents helped me gather warm, practical clothing, waterproofs, a new pair of work boots, basic toiletries and several books to pass the time. Mum's expression shifted constantly between relief that I had found employment and concern about the observatory's isolation.

"You'll call when you can?" she asked as we drove towards Oban.

"They have satellite internet, but it's limited," I reminded her. "I'll email whenever I can."

The supply vessel was waiting at the commercial quay in the working harbour, well away from the pleasure craft. It was a weathered Scottish creel boat, its paint scarred by years of hard use. A grizzled older man was checking lashings on deck. As we approached, he looked up and nodded.

"You the new technical assistant?" he asked, his voice as rough as his appearance.

"Yes. Daniel Chen." I offered my hand.

He regarded it for a moment before giving it a brief shake.

"Malcolm Reid. Captain Reid will do. We leave in twenty minutes. Say your goodbyes and get your kit aboard."

Mum's goodbye was tearful but quick, perhaps because she understood that prolonging it would only make matters worse. As she drove away, I stood on the quay beside my two duffel bags and watched the last connection to my old life vanish into the traffic.

Captain Reid was not conversational. Once we were under way, he withdrew to the wheelhouse, emerging only to inspect equipment, adjust lashings or check the creel gear stacked aft.

The accommodation consisted of a narrow bunk in a cramped cabin smelling of diesel, damp rope and fish. We ate sandwiches and drank tea whenever hunger demanded it rather than at fixed times. Bad weather slowed us during the second day, and we put into a small harbour for several hours to collect sealed cases of equipment and fuel drums intended for the observatory.

Later, while Reid coiled rope beside the creels, I attempted to start a conversation.

"Have you been to Gannet Island many times?"

"Supply runs every five weeks for three years," he replied without looking up.

"What's it like?"

He paused, his weathered hands resting on the rope.

"It's an island. Black rock, scrub, water on every side. Observatory's on the eastern shore."

"And the researchers? What are they like?"

His blue eyes settled briefly on me.

"They pay on time and don't ask me to remain any longer than necessary."

After a moment, he added, "Watch yourself in those waters. The currents round the island are treacherous. People who swim alone don't always come back."

With that cryptic warning, he returned to his work. I retreated to my bunk, wondering what I had agreed to.

The passage stretched into a fourth day, slowed by rolling seas and an unhelpful wind. Each hour merged into the next beneath the monotonous engine noise. My stomach had finally adjusted to the motion, although I would not have described myself as comfortable.

Late that afternoon, Reid called from the wheelhouse.

"Land ahead. We should dock before sunset."

I hurried to the bow for my first glimpse of my new home. Gannet Island emerged slowly from the haze, first as a dark stain on the horizon and then as a bleak mass of steep black rock. Dense, wind-stunted vegetation clung to its slopes. Cold reefs broke the slate-blue water around it, and a deceptively sheltered cove opened on the eastern side.

As we drew closer, the observatory resolved into a cluster of insulated prefabricated buildings tucked between the rocky shore and the thick scrub. A short jetty reached into the cove. Solar panels covered several roofs, and wind turbines turned on the ridge above. A radio mast stood against the darkening sky.

The compound was smaller than I had imagined. The descending sun threw long shadows across the water, giving the island an ominous silhouette. A cold breeze found its way through my jacket and raised gooseflesh along my arms.

"We'll dock in twenty minutes," Reid said, appearing beside me. "They'll be expecting you."

I nodded without taking my eyes from the island. This remote outpost would be my home for six months. It was my escape from failure, my chance to begin again. Yet the larger it grew before me, the harder it became to ignore my unease.

"Something wrong with the view?" Reid asked.

"No. It's just... more isolated than I expected."

He made a noise that might have been a laugh.

"You haven't seen isolated yet, son. Wait until you've spent a month here with the same four people and nowhere else to go."

Four people. With me, the station's entire complement would be five. The number struck me harder than I expected.

The engine dropped to an idle as we approached the jetty. I gathered my bags and took a breath, trying to suppress my apprehension. This job was my lifeline. Accommodation, meals and a salary that could begin to pull me out of debt. Whatever hidden costs accompanied it, I would have to cope.

By the time I stood on the jetty with my bags at my feet, watching Captain Reid secure the boat, the four-day journey already seemed unreal. The island itself looked less like a place where people lived than a fortress rising from the Atlantic.

"Mr Chen?" a woman's voice called from the head of the jetty.

I turned. A woman in her early forties was striding towards me in khaki trousers, sturdy boots and a pale blue work shirt beneath a windproof jacket. Her blonde hair was cut into a practical bob, framing an expression of pure efficiency.

"Yes. Daniel Chen." I extended my hand.

She took it in a firm grip.

"Dr Helen Ward. I'm the lead researcher and station supervisor." Her green eyes assessed me with clinical detachment. "I trust the passage was uneventful."

"As uneventful as four days on a creel boat can be."

She did not acknowledge the attempt at humour.

"Captain Reid, the usual supplies?"

"All accounted for," he said without looking up. "I'll have them ashore within the hour."

"Excellent." Helen turned back to me. "Bring your things. I'll show you the compound and introduce you to the team."

I hoisted my duffel bags and followed her up a narrow path. The air was sharp with salt and peat, and the wind made the short climb harder than it looked.

"We maintain a small team," Helen explained as we walked. "Besides you and me, Lewis Grant and Rhys Morgan handle security and most of the heavy maintenance. Tom Bell is our cook and general quartermaster. He has been here longer than any of us. Everyone takes on more than one role."

The main building was a two-storey insulated structure with solar panels across most of its roof. Several smaller units surrounded it, linked by gravel paths and covered walkways. Cables ran towards the turbines above, while a reinforced annex housed the radio room.

"This is the primary research building," Helen said, pushing open the door. "Laboratories and communal areas downstairs, living quarters upstairs."

The interior was unexpectedly modern: clean white walls, functional furniture and banks of sophisticated instruments. Two men at a workbench looked up from the sensor housing they were cleaning.

"Lewis Grant and Rhys Morgan," Helen said. "Security and maintenance."

Lewis was muscular, with close-cropped hair and the posture of someone with military experience. He gave me a curt nod. Rhys was leaner but equally fit.

"Welcome to paradise," Rhys said, with a trace of irony.

"And this," Helen continued as we entered the kitchen, "is Tom Bell."

An older man with salt-and-pepper hair tied in a short ponytail looked up from chopping root vegetables. His weathered face creased into something close to a smile.

"The new blood has arrived," he said, putting down his knife and wiping his hands on his apron. "Welcome to our little rock, Daniel."

"Tom has been here for more than ten years," Helen said. "He knows the island better than anyone."

"Not that there's much to know," Tom replied with a shrug. "Evening meal is at 18:30. Nothing fancy, but it'll keep you warm."

Helen continued the tour. She showed me laboratories without clearly explaining what was being studied, an instrument store, a workshop and the radio room. The legitimate work involved monitoring cold-water reef ecology, currents and underwater acoustics, but several terminals and filing cabinets were locked, and she passed over them without comment.

My quarters were on the first floor: a small, clean room with a bed, desk and compact shower room.

"You start tomorrow at 07:00," she said as I set down my bags. "Your main responsibilities are instrument maintenance, data organisation and general technical assistance. Any questions?"

I had dozens, but her manner did not invite them.

"Just one for now. Is there anywhere to swim? I could use some exercise after the journey."

Her expression hardened.

"Listen carefully, because this is the most important rule on Gannet Island. Never swim alone. The currents are unpredictable and extremely dangerous. People have disappeared here, including experienced swimmers. If you want to enter the water, you tell me, Lewis or Rhys, and someone accompanies you. Understood?"

"Understood," I said, taken aback by her intensity.

"Good. Get settled. The evening meal is in an hour."

She left me alone in my new home.

The next three weeks settled into a monotonous routine. I calibrated current meters, hydrophones and reef-monitoring instruments, organised research data into spreadsheets and helped with basic maintenance around the compound. The true purpose of much of the work remained obscure. Helen, sometimes accompanied by Lewis or Rhys, took boats to different parts of the island and returned with samples and encrypted datasets they never explained to me.

The isolation was worse than I had expected. Helen focused on her work to the exclusion of almost everything else. Lewis and Rhys were professional but distant, spending much of their time patrolling the perimeter, checking the boats or servicing security systems. Tom was the most approachable, but even he seldom lingered after preparing meals, disappearing into his quarters as soon as the kitchen was clean.

By late in my third week, I was going mad with restlessness. The lack of meaningful conversation and the repetitive work left me bored and irritable. I had read half the books I had brought, while the station's little library consisted mostly of technical manuals and research papers.

An exceptional warm spell settled over the island. One bright afternoon, after spending the morning recalibrating monitoring equipment in an overheated instrument room, I found myself staring through the window at the cove. The slate-blue water looked smooth and inviting. Sunlight shone across its surface, and the black rocks sheltered it from the worst of the wind.

Helen was locked in her laboratory. Lewis and Rhys were repairing a weather station on the far side of the compound, and Tom was preparing the evening meal. No one would notice if I took a quick swim.

I justified it easily. The cove was sheltered and the water calm. I was a strong open-water swimmer. I would stay close to shore. What danger could there be?

I changed into swimming trunks and followed a narrow path to a strip of pale shingle at the cove's edge. The stones were warm beneath my feet. I glanced back at the compound, saw no one watching and waded in.

The cold struck like a blow. My breath caught and every muscle tightened, but I forced myself to breathe steadily and kept moving until my body began to adjust. Once I ducked beneath the surface, the shock gave way to exhilaration. Salt water washed away the sweat, frustration and tension of the previous three weeks.

I surfaced and rolled on to my back beneath a cloudless blue sky. For the first time since arriving, I felt free. The compound receded into another world, its rules, routines and strained silences fading as I drifted.

The gentle movement of the water loosened my muscles. I closed my eyes against the brightness, drew a long breath and let myself sink beneath the surface, enjoying the muffled stillness below.

When I rose again and wiped the water from my eyes, something moved about 45 metres away.

At first I thought it was a shadow or a trick of the light. Then I saw a figure with long dark hair gliding smoothly through the cove.

I trod water and squinted. The figure moved with extraordinary grace, as though it belonged to the water. Long black hair streamed behind what appeared to be a woman's body.

"Hello?" I called. "Are you all right?"

The figure stopped.

For an instant, I thought a pale face turned towards me. Then it slipped beneath the surface without so much as a splash.

I turned in the water, searching for the swimmer to reappear. Nothing broke the surface. Within seconds the cove was peaceful again, as if nobody had ever been there.

"What the hell?" I muttered.

I swam towards the place where she had vanished, but found only clear, cold water and dark weed wavering over the rocks. After circling for several minutes, I reluctantly returned to shore.

Questions crowded my mind. Who was she? Helen had made it clear that the island's entire population consisted of the same four people I had met, plus me. The swimmer certainly had not been Helen, Lewis, Rhys or Tom.

I dried myself quickly, dressed and returned to the compound without being seen. The last thing I needed was to be caught breaking the rule against swimming alone on my first attempt. Yet for the rest of the afternoon I could think of nothing except the dark-haired figure.

By the evening meal, curiosity overcame caution. Tom had made a thick fish stew, and all five of us sat around the table in the common room. Helen discussed the following day's research schedule while Lewis and Rhys occasionally added brief comments about maintenance tasks.

I moved my food around the bowl, waiting for a natural pause.

"I was wondering," I said at last, trying to sound casual, "whether anyone else lives on the island."

Helen looked up sharply.

"No. Just the five of us. Why?"

I shrugged.

"I thought I saw someone swimming in the cove this afternoon. A woman with long dark hair."

Tom's spoon struck his bowl. In the sudden silence, the sound seemed unnaturally loud. His weathered face had gone pale.

"You saw what?" he whispered.

"Someone swimming. I called out, but she went under and disappeared."

I looked around at their faces.

"Why is everyone acting as though that's impossible?"

Helen shot Tom a warning glance.

"It was probably a seal. They occasionally enter the cove."

"It wasn't a seal," I said. "It was a person. A woman."

Tom leant forward, ignoring Helen's stare.

"You saw one of them. They're back."

"Tom," Helen said sharply. "Enough."

"He needs to know, Helen. Especially if he's been swimming alone."

Her jaw tightened.

"We are not filling his head with local superstition."

"Superstition backed by seventeen disappearances," Tom said. He turned to me, his voice taking on a deep, measured cadence. "This island has a dark history, Daniel. Twenty-four years ago, this wasn't merely a research station. There was a crofting and fishing settlement here. About fifty people lived on the island, families who had worked these waters for generations."

Lewis and Rhys exchanged uncomfortable glances but remained silent.

"Then the herring shoals vanished," Tom continued. "The seabird colonies went with them. One week the cliffs were deafening and the nets came up silver. The next there was hardly a bird in the sky, and every net was empty. The fishermen had to range farther from the island, out over deeper water."

"Tom, please," Helen interrupted. "This is not appropriate conversation for the dinner table."

He ignored her.

"That was when the men began disappearing. Experienced sailors. Capable swimmers. Men who had handled boats since childhood. Some vanished from their vessels. Others walked into the water alone and never returned. Seventeen in less than six months. Only a few bodies were recovered, and those were found elsewhere or weeks later. Most never washed ashore at all."

A chill ran through me despite the warmth of the room.

"What happened to the settlement?"

"The remaining families left. The island was abandoned until the observatory was built."

"That's ridiculous," I said, although my voice lacked conviction. "There must have been a rational explanation. Currents, perhaps, or exposure..."

"Did she look at you?" Tom interrupted. "Did you see her face?"

The image of that pale face turning towards me flashed through my mind. I hesitated too long.

"That is enough." Helen struck the table with the flat of her hand. "Tom, you know the rules about telling unsubstantiated stories to new staff."

"Rules won't keep him safe if he's swimming alone," Tom replied.

Helen stood.

"Daniel, I want to make this absolutely clear. The currents around Gannet Island are dangerous. That is why we use a buddy system. Whatever you saw was most likely a marine animal distorted by light and distance. Tom has a habit of turning natural phenomena into ghost stories."

Tom met her gaze without flinching.

"Call them what you like, Helen. They're out there. They always have been."

The rest of the meal passed in strained silence. Lewis and Rhys finished quickly and excused themselves. Helen remained at the table, apparently to prevent Tom from saying anything more.

I helped clear the dishes, my mind churning. Part of me wanted to dismiss Tom's account as the superstition of an old island hand. Another part remembered the swimmer's impossible grace and the completeness of her disappearance.

That night I lay awake, staring at the ceiling. The rational part of my mind insisted there must be a logical explanation. Perhaps another researcher was working elsewhere on the island and Helen had chosen not to mention her. Perhaps it really had been a seal, transformed by distance and an imagination starved of human contact.

But I could not forget the pale face turning towards me before vanishing without a trace. No splash. No bubbles. Nothing.

Tom's story played repeatedly in my head. Seventeen disappearances in less than six months. A settlement abandoned. Men walking into the sea alone.

I rolled on to my side and pulled the duvet higher, although the room was warm. Beyond the window came the distant sound of waves striking rock. It was the same shore where I had been swimming, the same water where I had seen her.

Helen was hiding something. Her reaction had been immediate and defensive, and the speed with which she had silenced Tom suggested that she had heard his story many times before. If it was merely superstition, why was she so concerned about my hearing it?

I sat up and switched on the bedside lamp. My mobile showed a few minutes past midnight. Sleep was not coming. The guarded data, the security personnel, the locked cabinets and the absolute rule about entering the water alone all seemed excessive for an observatory monitoring reefs and currents.

What were they actually studying? For nearly three weeks I had organised readings and calibrated hydrophones without being told what the data meant or what the underwater instruments were listening for.

I lay down again and closed my eyes, trying to force myself to sleep. Each time I began to drift, I saw the figure moving through the cove, black hair flowing behind her. And I heard Tom asking, "Did she look at you? Did you see her face?"

I tossed and turned, suspended between rational scepticism and a growing certainty that Gannet Island concealed something from me.

Morning arrived after a broken night. I dragged myself through breakfast, nodding mechanically as Helen listed my tasks: instrument calibration, data entry and the usual maintenance checks.

My attention remained in the cove, searching the water for a glimpse of dark hair.

"Daniel, are you listening?" Helen asked.

"Yes. Sorry. Instrument calibration. I've got it."

She studied me for a moment too long.

"You seem distracted. Is everything all right?"

"I'm just tired. I didn't sleep well."

She nodded, although her expression remained doubtful.

"Have some tea and concentrate. We have important work today."

I finished my assigned tasks by early afternoon, moving through them mechanically. All the while, my thoughts remained fixed on the cove.

The water seemed to call to me. I could almost hear a gentle whisper promising answers to questions I had not yet formed. When Helen disappeared into her laboratory and Lewis and Rhys began work on the far side of the compound, I made my decision.

Rules or no rules, I needed to know what I had seen.

I changed into my swimming trunks and slipped out by a different route. The cove was calm under the extraordinary sun, light scattering across its slate-blue surface. I waded in and endured the cold shock until my breathing steadied.

This time I swam with purpose, moving towards the deeper part of the cove and scanning the water around me. For twenty minutes I saw nothing but small fish, wavering kelp and shadows over the reef.

Then something moved to my right.

She appeared about 25 metres away, just as she had the day before. This time I saw her clearly.

Her skin was not merely fair but almost luminous against the dark water. Her black hair flowed around her like silk, moving with a grace no human swimmer could match. She did not appear to kick or pull herself forwards. Her body flowed through the sea as if she and the water were one substance.

I trod water, transfixed.

She turned towards me. I glimpsed high cheekbones, full lips and eyes that seemed to contain the depth of the ocean itself. Then, as before, she slipped beneath the surface.

I searched until the cold tightened my muscles and my shoulders ached, but she was gone.

Eventually I returned to shore, dried myself and entered the compound unnoticed. At the evening meal, Tom watched me with knowing eyes but said nothing. Helen discussed the next day's plans while I pushed food around my plate, my thoughts still in the water.

"Daniel, you'll assist me with sample collection tomorrow," Helen said. "We'll take the small boat to the western reef."

"Of course," I replied, already calculating how the trip would affect my chance of returning to the cove.

The following morning I accompanied her, going through the motions of collecting water samples, measuring temperature profiles and servicing a current meter. When she questioned my continued distraction, I blamed the strain of adjusting to island life. She did not look convinced.

As soon as we returned and my work was complete, I went back into the water.

The next two days brought further encounters. Sometimes I saw only pale skin beneath the surface or a strand of black hair vanishing into deeper blue. At other times she remained visible, watching me from a distance. She never approached and never made contact, but with every solitary swim I felt a bond growing between us.

There had now been four daylight encounters, beginning late in my third week and continuing through the following week. I became increasingly secretive, varying the times of my swims and the paths I took to the cove. When Lewis asked where I had been one afternoon, I claimed I had walked the island perimeter to clear my head. When Rhys commented on my wet hair, I said I had used the outdoor shower after working in the heat.

Helen grew suspicious. I caught her watching me through windows, her green eyes narrowed in calculation. I began taking greater precautions, hiding a towel and a change of clothes in a dry hollow beneath an overhanging rock near the cove.

At night I lay awake sketching the swimmer's face on scraps of paper, trying to capture the impossible beauty I had seen. The drawings never came close, but making them fixed her more firmly in my mind. I concealed them beneath my mattress.

My work deteriorated. I made careless errors in data entry, which Helen pointed out with increasing frustration. Calibrations that should have taken an hour stretched to three because my thoughts kept wandering back to the cove.

By Friday, just short of a month after my arrival, the obsession consumed nearly every waking thought. I stood at windows staring at the distant shine of water. During meals I barely spoke, eating quickly so I could return to my room and add details to the sketches.

That evening, as the sun sank towards the horizon, I made another decision. All four encounters had taken place in full daylight. Perhaps sunset would offer something different. Perhaps the fading light would reveal what daylight concealed.

I waited until Tom served the evening meal, then claimed to have a headache and withdrew to my room. Twenty minutes later, I slipped through a side entrance and made my way to the cove beneath a sky turning gold.

The water looked different at sunset: darker and more secretive, streaked with muted orange and pink. I changed quickly and waded in, forcing myself through the initial bite of cold until it became the familiar pressure of the sea against my skin.

Instead of remaining within the sheltered cove, I swam towards deeper water beyond the natural wall of black rock marking its boundary. The rational part of my mind issued frantic warnings about currents, cold and safety procedures. I pushed them aside. I needed to see her again. Nothing else mattered.

The water grew colder beyond the rocks, and the seabed fell away beneath me. Sunset set the waves aflame as I pressed onwards, my heart pounding more from anticipation than exertion.

Twilight gathered. Behind me, the protective rocks diminished. Around me, the water deepened from slate blue to almost black. My arms maintained a steady rhythm, carrying me farther from the island with every stroke.

I had come in search of the pale woman who had haunted my thoughts for days, but empty water stretched in every direction.

Then I saw her.

She appeared only 10 metres away, floating motionless where a moment before there had been nothing but waves. Her skin shone against the darkening sky with a cold, internal light. Black hair spread around her shoulders and moved gently with the current.

Her eyes held me. They looked deep and ancient, reflecting something like starlight although no stars had yet appeared. Her expression was neither curiosity nor hunger, but something I had never seen on a human face.

I trod water, breathless, as she raised one pale hand. Her fingers extended towards me, beckoning.

Without breaking my gaze, she turned and began moving towards the open Atlantic, away from the island and the cove.

I followed without hesitation.

My body moved as though something else controlled it. The part of my mind that understood currents, hypothermia, exhaustion and the simplest rules of water safety fell silent. Nothing mattered except keeping her in sight and closing the distance.

Her movement was impossibly graceful, closer to flowing than swimming. She did not struggle against the sea. She belonged to it.

I pushed harder, my muscles burning as I tried to match her effortless pace.

More figures emerged around me from the gathering darkness, like stars appearing one by one. First two, then five, then dozens. All resembled women of the same unearthly beauty, their hair streaming like weed as they moved through the water. Their pale bodies glowed beneath the dark surface.

They surrounded me in a loose circle, diving and rising in patterns too intricate to follow. Sometimes I glimpsed faces with high cheekbones, full lips and eyes far too knowing. At other times I saw only pale limbs slipping beneath the waves.

Something entered my mind. It was not sound, exactly, but something like music, a silent song that bypassed my ears and reached directly into the oldest part of me.

It promised things I could not name but wanted desperately: belonging, understanding, completion.

I swam harder, arms and legs driving frantically through the water. I needed to reach them, to join their underwater dance. Whenever I drew close to one, she slipped away and another luminous figure appeared just beyond my fingertips.

The island disappeared behind me. I did not look back. I did not care. The compound, Helen, Tom's warning, all of it seemed trivial and remote beside what awaited me in the sea.

They led me farther from safety, out above water that fell into blackness. Their glowing bodies became the only light, pulsing with an inner radiance that drew me after them.

I felt no fear. The part of my mind that should have warned me about distance, exhaustion and current had ceased to exist. In its place was raw, overwhelming need.

I wanted to be with them. I wanted to belong to them. I wanted whatever their silent song offered.

I surrendered to the call and swam on automatically, chasing the luminous forms that remained forever beyond my reach.

Then my left shoulder went into a sudden, savage spasm.

My stroke collapsed. Before I could recover, I struck something hard and bright in the dark water. My chest and cheek slammed against a floating marker buoy, and its metal fittings scraped my skin. Pain and the jarring impact shattered the spell.

I came back to myself gasping, already exhausted, with seawater flooding my mouth as the black waves closed around me.

The sudden spasm tore through my shoulder just as I struck something hard and hollow. My chest slammed into a floating marker buoy, and the impact drove the breath from me.

In that instant of piercing pain, my mind cleared. I clung to the buoy and looked around, properly looked, and horror washed over me. The shore was gone. The observatory lights and the steep black outline of Gannet Island had vanished into the darkness.

I had no idea how long I had been swimming or in which direction. Endless black water stretched around me. The women had disappeared as well. One moment they had surrounded me, their pale bodies luminous beneath the surface, their silent song filling my head. The next, there was nothing.

There was no trace that they had ever existed. There was only me, alone in pitch-black water, with no visible landmark and the buoy rolling beneath my hands.

"Hello?" I called.

My voice sounded pitiful against the vastness of the North Atlantic.

"Are you there?"

No answer came except the soft slap of waves against my face. Panic burst through my chest.

I turned in the water, searching for the shore, the observatory lights or even the faintest outline of the island against the night sky. There was nothing. Darkness met more darkness in every direction.

"Help!"

My shout seemed to travel nowhere. The night swallowed it.

"Somebody help me!"

I tried to think rationally. I needed to choose a direction and swim, but every direction looked identical. My shoulder throbbed where the muscle had seized, and the pain spread down my arm. My breathing came in short, desperate gasps.

My limbs felt weighted with lead. How long had I been swimming? An hour? Longer? My muscles trembled with exhaustion as I fought to stay beside the buoy, but its wet casing gave me no proper grip.

Stay calm, I told myself, though my teeth were already chattering. Hold on. Keep your face above water.

My body would not obey. My injured arm failed first. My fingers slid from the buoy, and my legs no longer kicked with any strength. Each movement became harder than the one before it. I slapped weakly at the surface and slipped beneath it.

Cold water closed over my head.

I kicked desperately and broke the surface with a gasp, only to sink again seconds later. My lungs burned. My arms and legs refused to work. The third time I went under, I could not find the strength to force myself back up.

Water filled my nose and mouth. The burning in my chest intensified, then softened into a strange, peaceful numbness. As darkness narrowed my vision, I thought I saw them again: pale faces watching through the water, dark hair drifting like weed.

Were they returning for me? Had abandoning me here been their intention all along?

My consciousness began to slip away. The last air escaped my mouth in bubbles and floated towards a surface I would never reach.

Then strong hands caught my arms.

The grip was firm and human. I felt myself being hauled upwards, but I could do nothing to help. My body had nothing left.

The world went black.

I returned to life choking. Water surged up my throat and poured from my mouth. I rolled on to my side on coarse, gritty sand and vomited seawater.

My chest felt as though someone had struck it with a hammer. Every cough drove fresh pain through my ribs.

"That's it," a voice said. "Cough it out. Keep breathing."

It was Dr Helen Ward.

I opened my burning eyes. She was kneeling beside me with her hands still poised for chest compressions. Her blonde hair hung in wet strands around her face, and she was soaked from head to foot. A safety line was clipped to the belt around her waist and trailed back across the beach.

Behind her stood Lewis Grant and Rhys Morgan, both holding high-powered torches. Their beams swept across the cove and out over the slate-black water. Lewis's jaw was clenched. Rhys kept glancing between me and the sea.

I tried to speak, but another fit of coughing seized me.

"Don't talk yet," Helen ordered. Her voice was clinical, but something beneath it frightened me more than the cold. "Just breathe."

I nodded and concentrated on dragging air into my waterlogged lungs. Each breath felt like inhaling fire.

"You were nearly two kilometres beyond the cove," Rhys said quietly. "If Tom hadn't noticed your meal was untouched and your towel was missing..."

Helen silenced him with a look.

Lewis lowered his torch. "I checked the cove. Helen picked up the locator signal from the marker buoy and followed it out with the line. We only just found you."

After several minutes, my breathing steadied enough for Helen to help me sit. The beach rolled around me, and every muscle screamed in protest. She knelt directly in front of me and gripped my shoulders.

Her face was inches from mine, more intense than I had ever seen it.

"Daniel," she said, low and urgent. "I need to know. Did you see them? The women in the water?"

I hesitated, then nodded weakly.

The colour drained from her face. She released me and rose so abruptly that sand scattered beneath her boots.

"Lewis, get to the radio room. Use the satellite set and send a distress call to Captain Reid. Tell him to divert back and reach us at first light."

Lewis nodded and ran towards the observatory without a word.

"What's happening?" I managed. My voice was little more than a rasp.

Helen turned back to me, and I was shocked to see her hands trembling.

"You're leaving at first light on Captain Reid's boat."

"But I've been here just short of a month," I protested. "My contract..."

"Your contract is terminated. This is not negotiable."

The urgency in her voice and the tremor in her hands revealed more than any explanation could have done. Whatever had happened in the water, whatever those women were, had terrified Dr Helen Ward, the most composed person I had ever met.

"Can you stand?" Rhys asked, offering me his hand.

I nodded and let him pull me upright. My legs shook so violently that they barely supported me. Rhys put my arm across his shoulders.

"We need to get you warm and dry," Helen said, taking my other side. "Then you need to pack. Captain Reid will take you off the island as soon as he arrives."

They half carried me along the path towards the observatory. My legs felt boneless and occasionally buckled beneath me. Painful aftershocks from the shoulder spasm travelled down my arm.

Salt coated my mouth and throat, making every breath feel as though it passed over sandpaper. Helen said nothing as we struggled up the path, but her fingers dug into my arm with unusual force.

I had seen her annoyed, stern and utterly focused. I had never seen her afraid. The naked fear on her face when I confirmed that I had seen the women transformed her.

Rhys's torch beam bobbed ahead, cutting through the dense, wind-stunted vegetation. Fragments of the night replayed in my mind: luminous skin, synchronised movements and the silent song that had filled my thoughts with promises while drawing me farther from land.

It had not been a hallucination. Helen's reaction proved that.

"Hold on."

Tom Bell stepped from the darkness ahead. His ponytail had come loose, and his expression was grim. He took in my drenched, shaking body with knowing eyes.

"So it happened," he said. It was not a question.

Helen gave a curt nod. "Lewis is making the distress call. Captain Reid will take him away in the morning."

Tom fell into step beside us as we continued towards the insulated prefabricated buildings.

"You need to understand what nearly happened to you," he said quietly. "Those things you saw are not human."

I opened my mouth, but produced only a hoarse cough.

"Save your strength," Tom said. "Just listen. Those creatures have been here longer than any of us can say. Twenty-four years ago, before this observatory existed, there was a crofting and fishing settlement on Gannet Island. First the local herring shoals vanished. Then the seabird colonies deserted the cliffs almost overnight. After that, the men began hearing the call."

We passed through the observatory's side entrance. Security lights cast the gravel, aerials and turbine towers into harsh relief. Tom continued despite Helen's tightened expression.

"The men could not resist it, just as you could not. They went into the water alone and did not return. Seventeen disappearances before the settlement was abandoned. Only a few bodies were ever recovered, elsewhere or much later. Most simply vanished."

"Tom," Helen warned.

He ignored her.

"The observatory does monitor cold-water reefs, currents and marine acoustics. That work is real. But it was also established to study those creatures and keep people away from them. That is the true reason for the swimming rule. A second person interferes with their ability to lure a target. They are strongest when a man is alone."

Rhys pushed open the door of the main building. From the radio room came Lewis's urgent voice as he repeated our coordinates over the satellite set.

"You're lucky to be alive," Tom added while Helen steered me towards the stairs. "Most men who get as far as you did never reach land again."

Helen gave him a withering look. "That is enough, Tom. Daniel needs warmth and rest before Captain Reid arrives."

Tom stepped back, but held my gaze.

"Remember what I told you," he said. "Stay away from the water tonight."

In my room, I peeled off my salt-stiffened clothes with trembling hands. Even after a hot shower had turned my skin red, I could not shift the chill lodged deep in my bones. I dragged out my holdalls and began throwing in clothes, books and toiletries. My movements were jerky and uncoordinated.

The observatory walls suddenly seemed as thin as paper.

Even in my first-floor room, I could feel the sea calling to me. It was a persistent pull within my mind, like a melody I had almost remembered. I pressed my palms over my ears, but it made no difference. The call was not entering through them. It was already inside my head.

I sat on the edge of the bed beside my half-packed bag and tried to understand what had happened. Had supernatural creatures truly enchanted me?

The part of my mind trained by a four-year integrated master's engineering course still believed in physics, measurement and repeatable evidence. It searched frantically for other explanations: oxygen deprivation, a toxin released by algae, some acoustic phenomenon that had caused hallucinations.

Yet I could not deny what I had experienced. The women had been real. Their soundless song had passed through every rational defence and taken command of my body. Without the marker buoy breaking their hold, and without Helen following its locator beacon, I would have drowned.

Or something worse would have happened, if Tom was right.

Sleep was impossible. I paced the cramped room and stopped occasionally to force another possession into a bag. Every few minutes I found myself drawn towards the window overlooking the cove, though I kept the curtains firmly shut.

The pull was subtle but relentless, like a gentle current circling my ankles.

By dawn, my eyes burned with exhaustion, but my mind remained painfully alert. I had packed everything except the drawings of the woman's face. I tore those into tiny pieces and flushed them down the lavatory. I wanted no reminder of her.

A knock at the door made me jump.

"Captain Reid is here," Helen called. "It's time."

I shouldered my bags and followed her downstairs. Neither of us spoke as we walked to the landing stage, where Captain Malcolm Reid's weathered Scottish creel boat moved against its lines. It was the same boat that had brought me to Gannet Island just under a month earlier, although it seemed that years had passed.

Lewis and Rhys were nowhere in sight. Only Tom stood at the end of the landing stage, hands in his pockets, while Captain Reid secured a line. The skipper looked up as I approached, his lined face revealing nothing.

"Heard you had some trouble," he said.

I nodded, not trusting my voice. The cove lapped gently against the pilings, perfectly innocent in the grey morning light.

Helen helped load my bags aboard. Her movements were brisk and impersonal. When I turned to her, her expression was unreadable.

"The confidentiality agreement in your contract remains legally binding," she said. "Remember that."

I nodded again, understanding at last why the pay had been so generous for apparently routine instrument maintenance. They had not merely paid for my engineering skills. They had paid for my silence.

I stepped aboard and felt the deck shift beneath my feet. Captain Reid started the engine without ceremony and took the boat away from the landing stage.

I stood at the stern. Helen remained motionless on the dock, arms folded, as Gannet Island receded into mist and the steep black rock sank behind the swell.

Two contrary sensations pulled at me. Relief grew with every metre between me and the island. Beneath it was an inexplicable grief, as though I were abandoning something essential to my existence.

Captain Reid said little during the four-day passage to Oban, slowed by rough weather and a scheduled supply stop. I spent most of it in the cramped cabin, listening to the engine's monotonous drone and trying to ignore the silent melody playing at the edge of my thoughts.

When we finally reached the commercial quay at the working harbour, I thanked him with all the sincerity I could muster. He merely nodded.

"I've been doing this run for three years," he said as I gathered my bags. "You're the first person they've sent back early."

I could think of no answer. I went down the gangway without looking back.

My mum cried when I appeared at the suburban house without warning. I told Margaret Chen that the observatory post had not worked out.

"Technical problems with the instruments," I claimed.

She did not press me. She welcomed me home, brought tea down in a mug and made up the sofa-bed in my parents' converted cellar.

I began applying for jobs at once. I could not bear idleness, because stillness gave my thoughts too much room to return to the sea. Within three weeks, I secured a junior position with a process-engineering firm on the outskirts of Glasgow.

The work was not revolutionary. I optimised production processes and investigated mechanical failures, but it kept my hands occupied and anchored my attention to the present.

I found a modest flat in East Kilbride, twenty minutes from the office on a good day. I chose it deliberately, away from the coast, reservoirs and major rivers. The rent swallowed nearly half my pay, but distance from deep water mattered more than comfort.

My new colleagues invited me for drinks after work. I went occasionally and made the minimum effort necessary to appear normal. I laughed at their jokes, contributed vague remarks to conversations about football clubs I did not follow and deflected personal questions with a story about a previous job maintaining equipment on a research vessel.

Nobody needed the truth. I had not fully processed it myself.

Sometimes, while writing a report or sitting in traffic, I wondered whether any of it had happened. Perhaps I had hallucinated the women, their silent song and the light beneath their skin. Perhaps I had simply swum too far, become disorientated and nearly drowned from exhaustion and cold.

Then I remembered Helen's face when she asked whether I had seen them. I remembered the fear in her eyes and Tom's account of men who had never returned. I knew it had been real.

I established rules. No swimming. No beaches, boats or fishing trips with colleagues. I took showers instead of baths and never filled the tub more than a few inches if I needed to soak a sprained ankle.

I crossed roads to avoid ornamental fountains in Glasgow. During heavy rain, I stayed inside until the worst had passed and the drains had cleared. People noticed my habits but dismissed them as eccentricity. Once, my supervisor remarked that I was the only engineer he knew who refused every fishing trip.

I laughed and claimed to suffer from seasickness. The lie came easily.

The dreams began about two months after I returned.

They were always the same. I stood on a shore, sometimes the cold cove at Gannet Island and sometimes a beach I did not recognise. The water began to glow. Dark heads surfaced, and pale faces turned towards me.

Then the song entered my mind, promising things I could not name but desperately wanted. I walked forwards. Water rose around me, cold yet welcoming.

Just before it covered my head, I woke.

The first time, I sat bolt upright with my heart hammering and my sheets soaked in sweat. I stumbled to the bathroom, splashed water over my face and froze when I tasted salt on my lips.

It was not sweat. It was seawater.

I spat into the basin and rinsed my mouth again and again, desperate to remove the taste that brought the island rushing back.

The dreams became more frequent. Once a week became twice, then almost every night. I woke with salt on my lips, a longing I refused to name and the fading echo of that silent song.

Sleep deprivation became my constant companion. Dark circles formed beneath my eyes, and colleagues asked whether I was ill. I blamed insomnia and drank more coffee.

Six months after leaving Gannet Island, I returned from work to find a plain courier envelope outside my flat. No sender was shown. My name was written in neat, exact handwriting that I recognised as Helen's.

I carried it inside and placed it on the kitchen table. I stared at it while eating a ready meal. Part of me wanted to throw it away unopened. Whatever it contained could only pull me back towards something I was trying to escape.

Curiosity won, as it always had.

Inside was a waterproof document wallet containing papers and photographs, together with a sealed letter bearing my name. I opened the letter first. It was handwritten on waterproof field paper.

Daniel,

I have debated whether to send you this information. In certain circumstances, knowledge can be as dangerous as ignorance. After what happened, however, you deserve to understand what you encountered and why you must remain vigilant for the rest of your life.

I lowered the letter and took a deep breath. My hands were shaking. Then I continued.

The entities you saw are not unique to Gannet Island. Accounts of similar beings extend across several centuries and cultures. The observatory was established after the island's crofting and fishing settlement was abandoned twenty-four years ago. Its public work on reef ecology, currents and marine acoustics is legitimate, but its restricted purpose is to study these entities and the disappearances associated with them. What I have enclosed is a small portion of our findings.

I looked at the document wallet, then returned to the letter.

Some researchers believe the entities are an unknown marine predator with an advanced method of creating psychic lures adapted to individual prey. Others regard them as a phenomenon that cannot be explained biologically, and possibly as the source of siren folklore. Old Hebridean oral accounts call them "the Hungry Below" and warn against answering voices from deep water.

I spread the contents of the wallet across the table.

The evidence came from Iceland, Cornwall, the Aegean and Hokkaido. Some reproductions were centuries old: woodcuts, sailors' sketches and paintings of drowning men reaching towards beautiful women among the waves. Recent digital photographs showed the same luminous skin and dark hair I remembered.

Research papers traced patterns among the missing. Recorded victims were overwhelmingly solitary men and usually capable swimmers. Reports on the few bodies recovered described peculiar findings. Some had little or no water in their lungs, suggesting that they might have remained alive below the surface before dying from another cause.

One paper proposed a hunting mechanism. The entities appeared able to establish a psychic connection with chosen prey, projecting emotion and desire directly into the mind. Repeated solitary exposure strengthened the connection. Physical separation weakened it but did not necessarily remove it.

That explained the dreams, the taste of salt and the lingering call I felt even far inland.

Helen's letter continued.

Daniel, you must understand that once they have marked someone, the connection may never fully break. You are one of very few people known to have seen them at close range and returned. Most men drawn as far as you were never seen again.

The final paragraphs made my blood run cold.

You must never return voluntarily to the sea. The danger is not confined to Gannet Island. Any sufficiently deep water connected to the sea may leave you vulnerable. They are patient hunters. They need not pursue prey when they can wait for it to return.

The call may diminish, but it will never disappear. Your only defence is distance from water deep enough for them to inhabit, and the presence of other people if exposure cannot be avoided. They have entered your mind once. They will not forget you.

I sat at the kitchen table until dawn, reading every document and studying every photograph.

Several files concerned research subjects, all men, who had encountered the entities and been monitored afterwards. Many eventually returned to the water despite repeated warnings, driven by what they described as irresistible longing.

None was seen again.

As daylight seeped through the blinds, I gathered the papers and photographs, replaced them in the waterproof wallet and laid Helen's letter on top. Then I closed it and pushed it away.

I understood that my escape from Gannet Island had not been an ending. The shoulder spasm, the collision with the marker buoy, Helen's rescue and my return to Britain were not victories. They were delays.

The entities had touched something within me that could not be untouched. A thin but unbreakable thread joined my mind to theirs. Somewhere beneath distant waves, they waited with inhuman patience.

The song persisted in the depths of my consciousness, quieter but unceasing: a promise, an invitation and a hunger that would never be satisfied until I answered.

Seven years later, I caught my reflection in a conference-room window. I was thirty-two, dressed in a tailored suit and presenting schematics for an industrial seawater filtration system to executives who nodded at efficiency figures few of them fully understood.

The irony was not lost on me. I had built a successful career designing industrial filtration and coastal intake systems, yet I had never once attended a live test beside deep water.

"That concludes my presentation on the new pre-filtration system for the Cromarty Firth seawater project," I said, moving to the final slide. "Any questions?"

The room remained quiet for a moment before applause began. My director, Peter Shaw, rose with a broad smile.

"Daniel, you've surpassed yourself again. The Cromarty Firth project could transform how we approach coastal intake filtration."

I forced a smile and packed away my laptop while the executives discussed implementation dates. Nobody questioned why the lead engineer always delegated field testing. They assumed I was too valuable to spend days on site.

The truth was simpler and much more complicated.

Back in my office, I shut the door and loosened my tie. My calendar showed a company retreat beside Loch Lomond the following month. I had already prepared an excuse, a family emergency that would arise conveniently on the day before departure.

It was the same excuse I had used for a conference in Brighton and, before that, a client meeting at Liverpool docks.

My mobile vibrated with a message from Peter.

Celebration drinks at The Quayside tonight?

I replied at once.

Sorry, early start tomorrow. Another time?

It was another rule in the life I had constructed: no restaurants overlooking the sea, no aquariums, coastal holidays or ferry journeys. I had declined a promotion involving regular visits to our Reykjavik office because it required frequent flights across the North Atlantic. Whenever possible, I even planned driving routes that avoided bridges over deep water.

Most people believed I had severe aquaphobia. That was close enough to the truth that I never corrected them.

My flat in East Kilbride had been chosen specifically for its distance from the coast, reservoirs and major rivers, although the commute cost me extra time each day. Its walls held desert landscapes and mountain scenes. There was no picture of water anywhere. The bathroom had a shower enclosure rather than a bath, and I never filled the kitchen sink beyond halfway.

That evening, rain hammered my windscreen as I drove back from a site visit in Wester Ross. A severe Atlantic storm had intensified throughout the day. Surface-water warnings appeared on overhead signs and flashed across my mobile before I put it away.

I should have taken a room near the site, but the prospect of being trapped in an unfamiliar hotel during the storm made my skin crawl. I chose an inland route, only to meet a Police Scotland diversion where flooding had closed the road.

An officer in waterproofs directed traffic towards the A832 coast road, the only available route around the closure.

I lowered my window a fraction. "How bad is the flooding?"

"Bad inland," the officer shouted over the rain. "The coast road is passable for now. Take it slowly and follow the diversion signs."

My hands tightened on the steering wheel as I joined the A832.

The road twisted between steep rock and a sea loch connected to the Atlantic. In clear daylight, drivers stopped in lay-bys to photograph the mountains and dark water. That night, through rain and darkness, I heard waves striking the rocks below. I fixed my eyes on the carriageway and refused to look towards the loch.

The rain grew heavier. My wipers struggled, and surface water gathered across the tarmac. The tyres threw spray from deepening pools. I slowed to 30 mph, then 20.

My mobile rang through the car's hands-free system. Peter's voice filled the cabin.

"Daniel, where are you? This storm is getting serious."

"On the A832," I said, unable to conceal the tension in my voice. "The inland road is flooded. Police sent us along the coast."

"Be careful. They're calling it the worst storm in years. Can you pull into a lay-by until it eases?"

I peered through the windscreen. On my left, black rock rose almost vertically. On my right, a crash barrier ran above the water. There was nowhere safe to stop.

"Not here. I'll be all right. Speak tomorrow."

I ended the call and leaned forwards, straining to see through the rain. The road curved sharply ahead. I eased off the accelerator and touched the brakes.

Too late, I saw a broad sheet of water crossing the carriageway.

The car struck it at barely 15 mph, but that was enough.

Aquaplaning felt like floating: a sudden, sickening lightness as the tyres lost contact with the road. I steered gently in the direction of the skid, as I had been taught, but the car continued sideways.

The crash barrier appeared in the headlights. One section had already been damaged by the storm or an earlier impact. It rushed towards me with terrifying speed.

The collision was deafening. Metal shrieked against metal. The damaged barrier buckled and gave way.

For one suspended moment, the car balanced at the edge, its headlights illuminating rain and empty darkness. Then it fell.

Time stretched during the drop. I braced against the steering wheel and crossed my arms before my face. The airbag exploded out on impact, punching the breath from my lungs.

The car plunged into the sea loch. Cold water burst through damaged seals and flooded the footwells.

"No. No, no."

I fumbled for the seat-belt release. Water reached my knees, then my waist. The car sank nose first, tipping me against the restraint. The release would not move.

I pressed it repeatedly as the water rose to my chest. The electrics failed, and the cabin fell into darkness.

I reached towards the glove compartment and searched for the emergency tool I had carried for years, a combined belt cutter and glass hammer. Water climbed to my neck.

I drew one deep breath before it covered my face. My fingers found the tool. I cut through the belt and pushed myself towards the driver's window.

I struck the corner of the glass. Nothing happened. The difference between the pressure inside and outside still held everything rigid.

I waited in darkness while the cabin filled, fighting the instinct to waste my remaining air. Only when the water had nearly reached the roof and the pressure had almost equalised did I strike again.

The glass shattered.

The last rush of water filled the car. I squeezed through the opening and pushed away from the sinking wreck.

Darkness surrounded me, absolute and disorientating. I kicked towards what I hoped was the surface and pulled with both arms. The car had entered close to the rocks, but in the black water I could see neither shore nor sky.

My lungs were close to giving out when pale light appeared below me.

There were dozens of them.

They were the women from Gannet Island. Their skin shone with the same unearthly light I had never forgotten. Dark hair flowed around flawless faces, and their eyes held ancient knowledge and hunger.

Long fingers reached towards me, inviting me down.

The silent song entered my mind again, bypassing my ears and speaking directly to thought. It was stronger than I remembered, as though seven years of separation had sharpened rather than weakened it.

It promised everything I had ever wanted: belonging, understanding and completion. It promised release from vigilance and from the loneliness of the life I had built. It promised peace.

I hung suspended, my body angled upwards towards air and life while my mind sank towards their open hands.

Helen was not there to rescue me. There was no observatory team on the beach with torches and a safety line. I did not know that another driver had seen my tail-lights vanish through the broken barrier and immediately called Police Scotland. I did not know that the police, Scottish Fire and Rescue Service, HM Coastguard and the RNLI were already being alerted.

In that moment, I believed nobody knew where I had gone. I believed nobody was coming.

The women drifted closer. Their synchronised motion was more beautiful than any human dance. Their song filled my mind until it smothered the pain in my lungs and the cold entering my bones.

One of them moved ahead of the others. I knew her. She was the first woman who had beckoned to me at Gannet Island.

Her hand stopped centimetres from my face.

All I had to do was take it. All I had to do was stop fighting.

Darkness gathered at the edges of my sight. My lungs screamed for air.

The choice was simple: spend my last strength swimming upwards or surrender to her embrace.

I thought of Helen's letter and the men who had disappeared. I thought of seven years spent running from water, of the dreams and the taste of salt on my lips. I thought of the life I had built despite them.

With the last of my strength, I kicked upwards and away from the reaching hands.

The woman's face changed. Its beauty fell aside and revealed something ancient and terrible. Her mouth opened impossibly wide, exposing teeth that had never belonged to anything human.

I broke the surface with a desperate gasp. Air had never tasted so sweet.

Rain lashed the loch. I had surfaced close to jagged rocks below the road, and above them headlights had stopped beside the broken barrier. Torch beams searched the water.

I raised one arm and shouted. My voice was frail against the storm, but someone on the road shouted back.

A Coastguard rope team was arriving to mark my position from above while firefighters secured the roadside. Farther out, through the rain, the engine of an RNLI inshore lifeboat carried across the loch from the direction of the nearest station.

"Hold on!" someone called.

I heard the words "lifeboat" and "we can see you".

As I trod water, the pull from below strengthened. The song changed from seduction to command. The water around my legs grew colder.

Something brushed my ankle.

Fingers closed around my calf.

I kicked free and struggled towards the rocks. Behind me, pale faces broke the surface and watched with inhuman patience. They did not pursue me into the shallows.

They did not need to.

They had time. They always had time.

Blue emergency lights flickered across the road above. A Coastguard rescuer directed a torch beam on to me, guiding the approaching lifeboat. I caught a projection of black rock and clung to it while the current tried to draw me back towards deeper water.

The silent song continued inside my mind. Its constant pull demanded constant resistance.

I knew then, with absolute certainty, that this would not be our final encounter. They had found me once, and they had found me again. The connection they had established would never break completely.

Their song would call until my dying day, an eternal temptation requiring eternal vigilance.
