Whose Signature on the Blades?

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

The maintenance tag lay on Ewan Stirling’s workbench like a dead thing. Iona stood in the workshop doorway, her waxed jacket still carrying the January wind’s bite, and watched the old man’s hands freeze above the metal surface. His fingers, stained dark with decades of grease, trembled as they hovered—caught between reaching and recoiling. The single hanging bulb overhead swung in the draft, throwing shadows that slid across his weathered face.

Ewan’s cap, the Harbour Master’s cap he still wore though he’d surrendered the rank thirty years ago, sat low on his brow. He didn’t look up. His eyes stayed fixed on the yellowed paper tag, on the date scrawled in faded red ink: February 14, 1986.

“You broke into the Control Room.” His voice came out flat. The smell of cutting fluid and old machine oil hung thick between them.

“I found what someone wanted hidden.” Iona stepped closer. Her boots scraped the concrete. The workbench was cluttered with wrenches and rags, but the space around the tag remained empty, as if Ewan had been clearing it for exactly this. “A turbine failure. Catastrophic, from those maintenance codes. And this tag—this tag proves it happened on the fourteenth.”

Ewan’s hands dropped to his sides. He exhaled, a sound that seemed to empty his lungs of decades. When he spoke again, his voice had dropped to barely a whisper.

“What did you find in there?”

Iona pulled out her notebook, flipping to a copied page. “I found proof of a catastrophic failure on the fourteenth. The turbine seized. It wasn’t routine.” She held up the maintenance tag, its stamped date clear. “The official logs say one thing. The maintenance record says another. They can’t both be true.”

The old man turned away. His shoulders hunched beneath his grey wool sweater. He walked to the window overlooking the channel, his movements slow and deliberate, like a man approaching a gallows. The bulb’s light caught the deep lines around his eyes, the set of his jaw that spoke of long practice at keeping secrets.

“You’re not the first to ask questions about that night.” Ewan’s reflection in the glass was ghostly, translucent. “But you’re the first to find proof. The rest—they just had stories. Stories we could contradict with other stories.”

“Who is ‘we,’ Ewan?”

He didn’t answer. Instead, he reached up and removed his cap, revealing white hair beneath. He turned the cap over in his hands, tracing the embroidered anchor with a thumb that still bore the calluses of working life. When he finally turned back, his eyes were red-rimmed and wet.

“The fourteenth of February.” He said it like a prayer, or perhaps a curse. “I remember the sound. You can’t forget a sound like that. Metal screaming against metal. The whole station shaking. We thought the foundations would crack.”

Iona moved closer, her notebook forgotten. This was what she’d come for—not just confirmation of forgery, but the sensory truth of that night. The archives gave dates and codes. Only a witness could give her the horror.

“Tell me what happened.”

Ewan set his cap down on the workbench, next to the maintenance tag. His hands no longer trembled—they were oddly still now, as if the decision to speak had drained the tension from his body. When he began, his voice took on the cadence of a recurring nightmare.

“The turbine had been making noises for weeks. Low groans, vibrations in the floor. Callum—he was the junior engineer, the one who actually got his hands dirty—he’d been logging complaints since January. But management wanted to keep it running. The sale was coming. The new buyers wanted proof of consistent output, and a shutdown for repairs would have shown in the quarterly reports.”

He paused, swallowing hard. The muscles worked in his throat.

“That night, the fourteenth, I was on harbour duty. Monitoring the tides, the vessel movements. Fraser was the shift supervisor. Catriona was at the front desk, handling the logbooks. And Callum—“His voice cracked on the name. “Callum was down in the turbine hall, trying to nurse that dying machine through another cycle.”

Iona’s pen moved across her notebook, recording the names, the positions. Four witnesses. Four people in that station when the turbine failed. Four people who had signed off on logs that said nothing about catastrophic mechanical failure.

“The seizure happened fast,” Ewan continued. “One minute the turbine was running, the next it was throwing sparks and screaming like a wounded animal. Fraser hit the emergency shutoff, but the damage was done. The intake valves had jammed open. The channel was flooding the housing.”

“Where was Callum?”

Ewan’s face changed. The confession that had been flowing became a trickle, then stopped. He turned back to the window, and Iona watched his reflection’s jaw work, grinding against words that refused to come.

“Ewan.” She pressed him, her voice harder. “Where was Callum?”

“He went into the channel.” The words came out in a rush, as if saying them quickly would make them less true. “The tide was coming in. I told him not to go. The intake was blocked. He thought if he could clear the obstruction, the water would drain. He thought he could save the turbine. He thought—“Ewan’s voice broke completely. “He thought he could save us all from the inquiry that would come if the station failed.”

Iona felt the workshop’s cold sink into her bones. The channel. The intake. She had stood at its edge during low tide, had seen the slime-covered walls and the rusted grating. Even at low water, it was dangerous. At high tide, with a flooding turbine housing—

“He drowned.”

It wasn’t a question. Ewan nodded anyway, his cap clutched to his chest now like a shield.

“The current pulled him under. The water was so cold, so fast. By the time we got to him—“He stopped, his throat working. “We got him out. But he was gone. Twenty-seven years old. Engaged to be married in the spring.”

Iona’s mind raced, connecting pieces. The forged logs. The false timeline. Catriona’s story about Callum working late, Fraser’s account of routine maintenance. All of it designed to hide the truth: not a routine shift, but a catastrophe.

“Who gave the order to forge the logs?” She asked directly, watching his face for any flicker of evasion.

Ewan didn’t answer. His eyes went to the maintenance tag, still lying on the workbench, then to his own hands—the hands that had held the pen, that had written the lies.

“I wrote them.” His voice was barely audible. “I wrote the false entries. The routine maintenance schedule. The times and dates that would show nothing unusual happened that night.”

“Under whose orders?”

The silence stretched. Iona heard the distant crash of waves against the sea wall, the rattle of wind against the workshop’s corroded roof. The bulb overhead buzzed and flickered, casting them in alternating shadow and light.

Ewan’s shoulders sagged. When he finally spoke, his voice carried thirty-eight years of silence. “Rossiter. Alistair Rossiter. He was the site manager then, the one negotiating the sale. He said if the buyers found out about the failure, about Callum, the deal would collapse. He said the station would close, and we’d all lose our jobs. He said—“Ewan’s voice caught. “He said Callum was already dead. Nothing could bring him back. But we could still save the station. Save everyone else’s livelihood.”

Iona felt something twist in her chest. She pushed it down, forcing herself to stay focused on the facts, on the record she needed to build.

“The four of you.” She said it carefully, watching for his reaction. “You and Fraser and Catriona—and Rossiter. You all agreed to the story.”

Ewan nodded slowly. “We sealed the Control Room that night. Rossiter took the maintenance logs, said he’d handle the official report. He told us what to say, what to write. Fraser signed off on the shift records. Catriona logged the false entries in the duty book. And I—“He looked down at his grease-stained hands. “I wrote the false maintenance logs under Rossiter’s orders. He even had me practice for hours until I could forge Callum’s signature perfectly.”

The confession hung between them. Iona felt its weight—a man’s entire career, his self-image, collapsing under the evidence she had brought. But even as something tugged at her, she recognized what was missing.

“You’re telling me it was an accident. A mechanical failure that led to a tragic death. A cover-up to protect the sale.” She stepped closer, her voice dropping to match his. “But there’s something you’re not saying, Ewan. Something about Callum’s death that you’re still afraid to admit.”

Ewan’s head snapped up. For a moment, his eyes met hers—really met hers, without evasion or deflection—and she saw terror there. Raw, animal terror.

“I’ve told you everything.” But his voice shook, and his hands had begun to tremble again. “The turbine failed. Callum went into the channel. He drowned. We covered it up to save the station. That’s all. That’s everything.”

“It’s not.” Iona pressed forward, her archivist’s instinct for gaps and silences screaming. “Because you’re still protecting someone. You named Rossiter for the forgery order, but you won’t say what he knew about Callum’s death. You won’t say whether that order went beyond hiding a mechanical failure.”

Ewan’s face crumpled. For a long moment, Iona thought he would break completely, that the final truth would spill out. But instead, he pressed his greasy palms to his forehead, leaving dark smudges on his skin, and began to weep.

“I can’t.” The words came out broken, hitched. “I’ve carried this for thirty-eight years. Every night, I see his face. Every tide, I hear that turbine screaming. But I can’t—“He looked up at her, his eyes streaming. “You don’t understand what it would mean. What it would destroy. Not just me. Not just Rossiter. Everyone who was there that night. Everyone who built their lives on that lie.”

Iona watched him cry. She wanted to reach out, to offer some comfort. But she also wanted to shake him, to force the final piece of truth from his locked throat. Her hand tightened on her notebook until her scarred thumb ached.

“Callum Reid deserves better than a partial confession.” She said it quietly, but the words carried. “And so do you. Whatever you’re still holding back—it’s eating you alive. Has been for thirty-eight years.”

Ewan’s weeping slowed, then stopped. He wiped his face with the back of his hand, smearing grease and tears together. When he looked at her again, something had settled in his eyes—a decision, or perhaps a surrender.

“The channel.” His voice was hoarse. “If you want to know what really happened that night, you have to go into the channel. At the lowest tide. There’s something there—something that was never recovered. Something that would prove Callum wasn’t just checking the intake.”

Iona’s pulse quickened. “What? What was left behind?”

But Ewan shook his head, his cap pressed back to his chest like armor. “I’ve told you what I can. The rest—“He turned back to the window, toward the dark water beyond the sea wall. “The rest is in the channel. If you’re brave enough to look.”

She stood there, weighing her options. She could push harder, demand more. She could threaten exposure, leverage his guilt. But something in his face told her that the well had run dry. He had given her what he could—the forgery, the order, the accident. The rest was locked behind a terror that no pressure would crack.

Iona tucked her notebook into her jacket pocket. Her movements were precise, deliberate—the ritual of an archivist preserving the record. The maintenance tag still lay on the workbench between them, its yellowed paper a silent witness to thirty-eight years of lies.

“Thirty-six hours.” She said it to his back, to his reflection in the glass. “The next extreme low tide is in thirty-six hours. I’ll be there, Ewan. Whatever you couldn’t say—whatever’s still hidden in that channel—I’ll find it.”

Ewan didn’t turn around. But his shoulders hunched forward, and she heard him exhale—a sound that might have been relief, or might have been dread.

Iona left the workshop, the cold January air hitting her face like a slap. The wind carried salt and the distant cry of gulls, and somewhere below the station, she could hear the rhythmic crash of waves against the intake walls. She walked toward the sea wall, her boots crunching on gravel, and pulled out her phone to check the tide tables.

The app loaded slowly, the signal weak this far out. When the numbers finally appeared, she committed them to memory: low tide at 06:47, minus 0.4 meters. The lowest ebb of the month. A window of less than two hours when the channel would be accessible.

She stood at the wall, looking down at the churning water. The channel mouth was visible now—a dark gap in the concrete where the tide rushed in and out. In thirty-six hours, that gap would be exposed. The slime-covered walls, the rusted grating, and whatever Ewan had hinted at—whatever proof of Callum’s final moments had been left behind.

The maintenance tag burned in her pocket, evidence of a forgery. But forgery was a paper crime. Whatever had happened to Callum Reid in that channel—that was flesh and blood. That was a death that someone had hidden beneath layers of false documentation and collective silence.

Iona turned her collar up against the wind. Behind her, the workshop light still glowed through the single window, illuminating Ewan Stirling’s hunched silhouette. He had given her a name—Rossiter. He had given her a method—the forged logs, the sealed room. He had given her the shape of the tragedy.

But he had held back the heart of it. And that omission, she knew, was where the real story lay.

She walked back toward the main building, her mind already racing ahead. She would need gear—boots, a torch, perhaps a grappling hook for the deeper sections. She would need to understand the channel’s layout, the currents, the places where debris might have accumulated over three decades. And she would need to be careful. If Rossiter had ordered a cover-up once, if four witnesses had maintained their silence for thirty-eight years, they would not welcome someone digging through the literal and figurative wreckage of their secret.

The wind shifted, carrying with it the smell of kelp and diesel. Iona paused at the station’s main door, looking back one last time toward the workshop. Ewan’s silhouette had disappeared from the window. He was alone now with his confession, with the maintenance tag she had left on his bench.

She had broken him. She had extracted the truth of the forgery, the name behind the order. But the victory felt hollow. Because she knew, with the certainty that came from years of reading between the lines of damaged documents, that the worst truth remained unspoken. Whatever had happened to Callum Reid in that channel—whatever had terrified Ewan into silence even now—was still waiting to be discovered.

In thirty-six hours, the tide would turn. And Iona Kerr would be there to meet it.
