Chapter 2

Low Water, High Stakes

────────────────────────────────────────

The tide table showed a 47-minute window. Iona’s pen circled it, a countdown in red ink.

She sat alone in the station’s makeshift archive room, a converted office that smelled of damp concrete and old paper. The tide table was her first document, printed from the British Oceanographic Data Center’s archives, the numbers crisp and unambiguous. Low water at Kessock: 14:47. High water: 20:33. The spring tide meant the channel would drain further than usual, exposing the intake floor for less than an hour before the sea reclaimed it.

Forty-seven minutes. She underlined the figure twice.

What the forged entries could not do was move the body. Callum Reid, the engineer who had supposedly signed the duty log for February 1986, had drowned hours before his logged shift began. The handwriting analysis she’d requested would take weeks. But the physical evidence was available now, if she was willing to risk the channel during low tide.

She pulled the personnel file from the stack she’d requisitioned that morning. The manila folder was thin, the kind that suggested a life cut short. Callum Reid’s photograph paper-clipped to the inside cover showed a man in his late forties, thinning hair, the reserved smile of someone unaccustomed to having his picture taken. Twenty-three years at Kessock Tidal Station. Drowned in the intake channel, February 3rd, 1986. Body recovered the following morning.

The incident report was clipped behind his photograph. Iona had read it a dozen times already, but she read it again now, her finger tracing each line.

“Recovery site: eastern intake channel, approximately fifteen meters from the maintenance access ladder. Body found against the debris grate. Time of recovery: 07:12, February 4th. Estimated time of death: between 21:00 February 3rd and 02:00 February 4th, consistent with tidal submersion.”

She flipped to the duty log. The entries for February 3rd claimed Reid had been on shift from 18:00 to 02:00, performing routine checks in the turbine hall and control room. The eastern intake channel, where his body had been found, was never mentioned. The logs placed him nowhere near the water.

“Someone went to considerable trouble,” she murmured, turning to a fresh page in her notebook. “But they couldn’t change where the body was found.”

She wrote the four names in a column, the skeleton crew who had been on duty that night according to the station’s records. Alistair Rossiter, the site manager. Fraser Munro, senior technician. Ewan Stirling, junior engineer. Catriona MacAulay, operations assistant. Four witnesses, four accounts she would need to collect if she wanted to understand what had actually happened in the turbine hall on the night of February 3rd, 1986.

But first, she needed to see the channel for herself.

Iona checked her watch. 14:23. The tide would reach its lowest ebb in twenty-four minutes. If she wanted to reach the intake floor before the water began returning, she needed to move now.

She gathered her equipment into a waterproof bag: camera, measuring tape, flashlight, the incident report folded inside a plastic sleeve. The station’s eastern access corridor stretched beyond the archive room’s door, leading to the maintenance hatch that overlooked the intake channel.

The corridor was dark, the emergency lights casting orange pools at irregular intervals. Her footsteps echoed against the concrete floor. The station had been decommissioned for fifteen years, its machinery silent, but the building still carried the hum of latent power, the sense that something vast and dangerous slept just out of sight.

She passed the control room, its windows dark, the instrument panels dormant behind reinforced glass. The turbine hall’s massive doors stood sealed ahead, but she turned left before reaching them, toward a smaller door marked “Authorized Personnel Only” in faded red paint.

The door’s hinges groaned when she pushed it open. Cold air rushed past her, carrying the smell of salt and seaweed. A metal grate platform extended from the threshold, and beyond it, the channel dropped away into shadow.

Iona stepped onto the platform and looked down.

The intake channel was a concrete trench, thirty meters long and eight meters deep, designed to funnel seawater through the station’s turbines during high tide. Now, at low water, the channel was a dark canyon, its floor carpeted with black silt and scattered debris. The walls were slick with algae, marked with horizontal stains where the water usually rose. Far below, she could see the debris grate mentioned in the incident report, a massive metal screen designed to catch anything that might damage the turbines.

The maintenance ladder was mounted on the eastern wall, its rungs disappearing into the gloom. Rust had bloomed across the metal in orange patches, but the bolts securing it to the concrete looked intact.

She checked her watch again. 14:31. Sixteen minutes until low water.

The ladder would take her to the channel floor. From there, she could measure the distance from the access point to the debris grate, compare it to the incident report’s description of the recovery site, and determine whether the forged logs could possibly be accurate.

If Reid had been where the logs claimed, he would have been in the turbine hall, checking gauges. The eastern intake channel was nowhere near the turbine hall. It was on the opposite side of the station, accessible only through this maintenance hatch and the ladder below.

She tested the ladder’s top rung with her gloved hand. The metal held, though a flake of rust came away under her grip.

“The things I do for proper documentation,” she said, and began her descent.

The ladder groaned with each step, but held. The air grew colder as she descended, the temperature dropping as she moved deeper into the channel’s shadow. The smell of the sea intensified, brine and decay mixing into something sharp and ancient.

Twenty rungs. Thirty. The channel floor rose to meet her, the black silt glistening under her flashlight’s beam.

Her boot touched bottom, and the silt gave beneath her weight, sucking at her ankle with a sound like a wet gasp. She steadied herself against the wall, the algae cold and slick under her palm.

Fourteen-forty. Seven minutes until low water.

She oriented herself, pointing her flashlight toward the debris grate. It loomed at the channel’s far end, a massive metal screen now tilted at an angle, designed to rise during flood tides and lower during ebb. In its lowered position, it formed a barrier against anything floating in the incoming water.

According to the incident report, Reid’s body had been found against that grate, fifteen meters from the maintenance ladder.

Iona began walking, her boots sinking with each step, the silt pulling at her feet. She counted her paces, measuring the distance. Five meters. Ten. The walls rose around her like the sides of a tomb, the high-water marks staining the concrete far above her head.

She reached the grate and stopped.

The metal screen was massive, four meters tall, its surface crusted with barnacles and seaweed. But something else caught her flashlight’s beam, and she moved closer, angling the light.

A scrape in the concrete, low near the floor, where something had been dragged across the surface. The mark was faded, partly obscured by silt, but its shape was unmistakable. A body had been pulled from this spot, hauled toward the ladder, lifted out of the channel.

She took photographs, her camera clicking in the silence. The scrape mark. The grate. The walls rising above. Then she measured the distance from the mark to the ladder, counting her paces back.

Fifteen meters. The incident report was accurate. Reid’s body had been found here, in the eastern intake channel, far from the turbine hall where the logs claimed he had been working.

She crouched beside the scrape mark, her flashlight illuminating the silt around it. Something glinted in the mud, and she reached down, her gloved fingers closing around a small metal object.

A button. A standard work uniform button, corroded but intact, still attached to a fragment of fabric that had been caught on the grate’s edge and torn away.

She bagged the evidence and stood, her legs aching from the cold and the effort of moving through the silt.

The water reached her boots.

It was barely noticeable at first, a seep of cold around her ankles, but when she looked down, she saw the silt beginning to soften, the water rising from somewhere beneath. The tide was turning.

Iona checked her watch. 14:52. Low water had passed five minutes ago. The sea was returning.

She moved toward the ladder, her steps faster now, the silt yielding more easily as the water loosened its grip. The channel floor was changing, the solid surface dissolving into something treacherous.

She reached the ladder and grabbed the lowest rung, hauling herself up. Her arms burned with the effort, her fingers aching against the cold metal. The water followed her, rising inch by inch, filling the channel’s lowest points.

Twenty rungs. The water was at her knees now, the current pulling at her legs. She climbed faster, her breath coming in short gasps, her boots scraping against the rungs.

Ten rungs. The water was rising faster than she had anticipated, the spring tide surging back through the intake. She could hear it now, a rushing sound from somewhere beyond the grate, the sea reclaiming its territory.

Five rungs. Her hand closed around the platform’s edge, and she hauled herself up, rolling onto the metal grate as the water swirled below. The channel was filling, the black silt already submerged, the debris grate groaning as the pressure shifted.

She lay on the platform, her chest heaving, her clothes soaked from the knees down. The cold was a physical weight now, pressing against her skin, seeping into her bones.

She had made it. But she had also found what she came for.

Iona sat up, her hands trembling as she pulled the incident report from her waterproof bag. The recovery site was confirmed. The distance was accurate. Callum Reid had drowned in the eastern intake channel, far from the turbine hall, far from the control room, far from anywhere the duty logs claimed he had been working.

The forgery was not a clerical error. It was a deliberate lie, designed to place Reid somewhere he could not have been, doing something he could not have been doing, at a time when he was already dead.

She thought of the four names in her notebook. Rossiter, Munro, Stirling, Reid. The four people whose signatures were on the duty roster that included the forged entry. One of them had written the false entries. All of them had let the lie stand.

The water continued to rise below her, the channel filling rapidly now, the sea reclaiming the space where Callum Reid had died. In an hour, the intake would be completely submerged, the evidence hidden beneath meters of cold gray water.

But the evidence existed. The scrape mark. The button. The distance. The physical truth of a man’s death, preserved in the station’s concrete and silt, contradicting the official record with silent, irrefutable certainty.

Iona stood, gathered her bag, and walked back toward the door. The corridor seemed warmer now, or she had simply grown accustomed to the cold. The control room’s windows were dark as she passed, the turbine hall’s sealed doors silent.

She had come to Kessock Tidal Station to catalogue its records, to organize its archives, to bring order to its dusty history. Instead, she had found a murder disguised as an accident, a forgery designed to hide the truth, and four names that pointed toward answers she was only beginning to seek.

The four witnesses. The four people who knew what had really happened in the turbine hall on the night of February 3rd, 1986.

She would find them. She would ask them questions. And she would not stop until she understood why Callum Reid had died, and why someone had tried to erase the truth from the official record.

The station’s front door opened onto a gray afternoon, the sea stretching to the horizon, the tide rising against the shore. Somewhere beneath that water, the intake channel was filling, the debris grate tilting, the scrape mark on the concrete floor disappearing beneath the surge.

But Iona had seen it. She had measured it. She had photographed it.

But Iona had seen it. She had measured it. She had photographed it. The truth was not lost. It was simply waiting, like the tide, to be revealed.

She walked to her car, the evidence bag heavy in her pocket, the four names waiting in her notebook. The mystery had only deepened, but the first piece was in place. The logs were lies. The death was real. And somewhere in the gap between the two, the answer was hiding.

She started the engine and pulled away from the station, the sea rising behind her, the truth sinking deeper into the water, waiting for the next low tide to bring it back into the light.
