The salt of the River Wyre did not merely cling to the skin; it bit into it, leaving a crust that turned the collar of a wool jacket into a rasp. At half-past five in the morning, the harbor was a study in bruised purples and cold charcoal, the sky refusing to commit to either night or day. For Arthur Pringle, the transition was marked not by the sun, but by the groan of the incoming tide against the rotting green timber of the outer pilings. It was 1946, and though the guns across the Channel had fallen silent more than a year ago, the shipyard at Wyre Haven still carried the grim, oil-slicked posture of a fortress under siege.

Arthur stood at the edge of Slipway Four, his hands buried deep in the pockets of an oversized donkey jacket that had belonged to his older brother, Tommy. The wool was stiff, smelling permanently of stale tobacco, coal smoke, and the faint, sweet grease of a triple-expansion steam engine. To Arthur, the jacket was less a garment and more a shield, though against what, he couldn’t entirely say. The world was supposed to be rebuilding, softening at the edges, but here on the mudflats of the estuary, the peace felt like nothing more than a coat of gray paint slapped hastily over rusted iron.

Beneath him, the slipway sloped sharply into the murky water. The timber baulks, thick oak beams that had supported the weight of corvettes and minesweepers during the frantic years of the war, were black with weed. But it was not the weed that held Arthur’s gaze. It was the rust.

It wasn’t the ordinary, flaking orange decay that claimed any metal left to the mercy of the Lancashire rain. This was different. Along the steel launching tracks, where the heavy grease should have been thick and yellow as lard, there were streaks of an angry, chemical red. It looked like dried blood from a distance, but up close, it had the granular, powdery texture of iron filings mixed with acid. It was eating into the bearing surfaces, pitting the smooth tracks that had been laid down only three months ago during the celebrated "Postwar Reconstruction Initiative."

Arthur knelt, his knees clicking in the damp air. He extended a finger, dabbing at the residue. It was gritty, cold, and smelled faintly of sulfur—not the clean, sharp sulfur of a match, but the sour, rotten-egg stench of a chemical reaction gone wrong.

"You’ll catch your death down there, lad, and the yard won’t pay for the box."

The voice was dry and raspy, like gravel slid down a chute. Arthur didn’t need to look up to know it was Walter Vance, the senior shipwright whose legs had been left uneven by a falling deck plate during the heavy air raids of forty-one. Walter walked with a heavy, rhythmic lurch, his iron-shod boot striking the gravel with a metallic clink-clop that warned the apprentices of his approach from fifty yards away.

"Look at this, Walter," Arthur said, not rising. He pointed to the red streak. "The grease on the carriage guides. It’s gone dry. It’s burning the steel."

Walter halted, his shadow falling over Arthur like a heavy canvas tarp. He leaned heavily on his ash-handled walking stick, his rheumy eyes squinting down at the track. A cigarette, rolled so thin it looked like a splinter of pine, dangled from the corner of his mouth, unlit but thoroughly chewed.

"Aye," Walter grunted, coughing a wet, rattling cough that seemed to shake his entire frame. "The salt gets into everything. No such thing as decent tallow these days. Everything we get from the Ministry is watered down, stretched out with paraffin and god-knows-what. It’s peace-time grease, Arthur. Cheap and useless, like the peace itself."

"It’s not just cheap grease," Arthur insisted, scraping a fingernail along the groove. "Look at the pitting. It’s deep. If we run the cradle down this for the launch of the Sovereign next month, the carriages will bind. They could jam on the declivity. If she hangs up on the slipway, the tide will drop out from under her, and she’ll break her back on the stone."

Walter was silent for a long moment. The wind shifted, bringing the smell of frying bacon from the canteen across the wet basin, a tease of luxury that made Arthur’s stomach hollow out. The old man took the dead cigarette from his lips, stared at it, and tucked it behind his ear.

"The Sovereign isn’t our worry today," Walter said, his tone dropping into a lower register that lacked its usual bluster. "Today we’ve got the plating on the timber-carrier to finish. The office wants her out of the drydock by Friday, or the Swedes will take their timber elsewhere. Get your tools from the store, Arthur. Leave the grease to the maintenance gang."

"But I saw the maintenance sheet," Arthur said, rising to his feet and wiping his stained hand on the thigh of his trousers. "It was marked as oiled on Tuesday. Signed off by Miller himself. There’s no way three inches of industrial tallow disappears in forty-eight hours unless someone assisted it."

Walter’s hand reached out, surprisingly quick for a man who looked like he was made of dry driftwood. His fingers closed around Arthur’s forearm, not with violence, but with a sudden, heavy pressure that stopped the boy mid-breath. Through the thick wool of Tommy’s jacket, the grip felt cold.

"Listen to me, Arthur," Walter said, his eyes scanning the empty slipway, then looking up toward the high, glass-paned windows of the drawing office that loomed over the yard like a row of blank spectacles. "The war’s over. The men who spent six years holding their breath are trying to learn how to breathe again. Some of them are clumsy. Some of them are tired. If a grease-pot gets spilled, or a clerk signs a chit without looking, it’s because their minds are elsewhere. You start looking for devils in every corner, and you’ll find yourself out on the road with nothing but your grandfather’s pocket watch and a pair of leaky boots. Do you take my meaning?"

Arthur looked at the old man’s face. The skin was mapped with tiny blue-black scars—the "coal-tattoos" of a lifetime spent under heavy steel and flying scale. There was no anger in Walter's eyes, only a flat, grey exhaustion that seemed older than the shipyard itself.

"Yes, Walter," Arthur said quietly.

"Good," Walter said, releasing his grip with a small, stiff nod. "Now get the hand-drills. The wind’s coming round from the west, and if the rain catches us before we’ve got the temporary bolts in that port-side strake, we’ll be working in a bathtub."

The old man turned and began his slow, lurching progress back toward the tool stores, his clink-clop echoing against the towering steel sides of the half-finished hull in Drydock Two.

Arthur stayed behind for another minute. The tide was nearly full now, the brown, silt-heavy water of the estuary licking at the bottom-most timbers of the slipway. He looked down once more at the red trail on the steel. It didn't look like an accident. It didn't look like the mistake of a tired man. It looked like a deliberate, chemical erasure.

He reached into his pocket and pulled out a small, leather-bound pocketbook. Its black oilskin cover was warped by moisture, the pages thick and yellowed. It had been Tommy’s book, used for keeping track of rivet counts and overtime hours during the peak of the wartime rush. Now, it was Arthur’s ledger of doubts.

With a stub of pencil, he made a quick, neat sketch of the slipway track, marking the position of the red rust relative to the main concrete abutment. Beside it, he wrote a single word: Sovereign. Below that, he wrote: Tuesday—oiled?

As he closed the book, a shadow broke the grey light on the water. A small coaster was heading out toward the Irish Sea, its funnel belching a thick, oily plume of black smoke that hung low over the channel. The vessel was riding high in the water, her plates patch-painted and showing the salt-streaks of a hard winter. She looked tired, Arthur thought. Everything in Wyre Haven looked tired, as if the entire coast was waiting for a permit to lie down and rest.

He tucked the book away and walked toward the tool store, the gravel crunching beneath his boots.

The tool store was a long, corrugated-iron shed that sat in the permanent shadow of the great cantilever crane. Inside, the air was a thick mixture of paraffin, damp sacking, and the sharp, metallic tang of newly ground drill bits. Behind the wire-mesh counter sat old Hector, a veteran of the Somme who had lost his left hand to a German machine gun and now ran the store with a terrifying, one-handed efficiency that brooked no argument.

"Pringle," Hector muttered, not looking up from his ledger. "The brother’s boy. What’s the damage today?"

"Two half-inch high-speed drills, Hector. And a bucket of three-quarter bolts, hex-head, three inches long."

Hector reached up with his brass-tipped wooden prosthesis, hooked a bucket from a shelf with practiced ease, and dropped it onto the counter with a heavy clang. "Bolts are there. Drills are in the drawer behind you. Sign the book."

Arthur took the heavy pencil tethered to the counter by a greasy string. As he signed his name, his eyes drifted to the ledger page above his. The ink was fresh, the handwriting neat and clerkish.

Requisition: Slipway Four. Maintenance Grease, Grade B. 4 Drums. Delivered to J. Miller.

The date was yesterday.

"Hector," Arthur said, keeping his voice casual as he checked the point of one of the drill bits. "Did Miller come in for this grease himself?"

Hector looked up, his one good eye narrowing. "What’s it to you? You running the stores now? Or are you just naturally nosey?"

"Just wondering," Arthur said. "We were down by Four this morning. The tracks look dry. Walter said the grease might have been bad."

"Bad?" Hector spat into a sand-filled tin by his stool. "There’s nothing wrong with the grease. Best mineral stock we’ve had since thirty-nine. Miller took it down himself on the hand-trolley. Four full drums. I helped him hoist them."

"Yesterday afternoon?"

"Aye. Just before the whistle. Now take your gear and get out of my light. I’ve sixty boiler-makers coming in ten minutes, and every one of them’s going to tell me their mother’s dying just to get a newer hammer."

Arthur took the bucket and the drills, his mind spinning like a loose pulley. If four drums of grade-B grease had been delivered to Slipway Four yesterday afternoon, the tracks should have been thick with it. It should have been dripping into the mud, leaving a rainbow sheen on the rising tide. Instead, there was only that dry, red, sulfurous crust.

He walked out into the cold morning air, the heavy bucket banging against his shin. The yard was waking up now. The great air compressors in the powerhouse had started their low, rhythmic thumping—the heartbeat of the yard that didn't stop until the weekend shift finished on Saturday noon. From the fitting shops came the first screeches of the metal saws, a sound that set Arthur’s teeth on edge.

He headed toward Drydock Two, where the timber-carrier lay like a stranded whale in the deep concrete slot. To reach it, he had to pass the administrative block—a two-story brick building that looked out over the main gates.

The windows on the ground floor were dark, but on the upper floor, where the directors and the design staff worked, a single light was burning. Behind the gold-leaf lettering of Wyre Shipbuilders Ltd., a figure was standing by the window, looking out over the basin.

The glass was distorted by the morning condensation, but Arthur recognized the sharp, clean silhouette. It was Mr. Sterling, the assistant managing director, a man who had arrived at the yard six months ago with a clean collar, a leather briefcase, and a set of blueprints that no one below the rank of foreman was allowed to see.

Sterling didn't move as Arthur passed. He stood with his hands behind his back, watching the harbor as if he were waiting for something to rise out of the grey water.

Arthur pulled his collar up higher, the rough wool of Tommy’s jacket scraping his chin. He had a sudden, cold feeling that the tide wasn’t the only thing returning to Wyre Haven that morning, and that whatever was coming in with the water, it wasn't meant for the likes of him to see.

The wind off the Irish Sea had a way of finding the gaps in a man’s clothes, no matter how many layers of flannel and grease-stained denim he wore. As Arthur made his way toward the plating sheds, the cold dug deep into his collar, a reminder of his low standing in the hierarchy of Wyre Shipbuilders Ltd. He was nineteen years old, an apprentice shipwright in a yard that had no time for the slow, methodical learning of the pre-war years. Here, you learned by having your fingers pinched by five-ton plates or by getting your ears boxed by a foreman whose patience had been burned away by six years of blackout shifts and Ministry quotas.

To become an apprentice at Wyre Haven was to take an oath, though not one written on parchment or sealed with wax. It was a verbal contract, sworn in the presence of the yard manager and a union shop steward who smelled of cold tea and plug tobacco. You swore to keep the secrets of the trade, to obey the lawful commands of the journeymen, and to stay clear of the counting house unless summoned. In return, the yard promised to turn you into a man who could look at a curved sheet of four-inch steel and know exactly where to strike it with a twelve-pound maul to make it fit the ribs of a vessel.

But the oath had another, unwritten clause—one that every lad on the docks understood before he was allowed to sweep the shavings from the mold loft. You kept your mouth shut about what went into the mud, and you didn't ask why certain crates arrived from the railway siding under heavy canvas tarpaulins at three in the morning.

"Pringle! Stir your stumps, lad!"

The shout came from red-faced Jimmy MacNair, a plater who had worked at the yard since the days when the ships were built of timber and held together with wooden trunnels. MacNair was leaning over the edge of the staging on the timber-carrier’s port bow, his leather apron stiff with scale and dried sweat. He had a caulking mallet in one hand and a drift-pin in the other, his face decorated with grease smears that looked like war paint.

"I’ve got the bolts, Jimmy," Arthur said, hoisting the heavy iron bucket up the wooden rungs of the ladder. His muscles burned from the climb, the weight of the three-quarter hex-heads dragging at his shoulder.

"About bloody time," MacNair grunted, snatching the bucket and dumping a handful of the heavy bolts onto the wooden planks of the staging. "Old Hector must have had you doing his bookkeeping again. The man’s a menace with that wooden arm of his. I think he uses it to weigh the brass fittings so he can cheat the scrap merchants."

"He had the requisition book out," Arthur said, leaning against the cold steel of the hull to catch his breath. "He said Miller took four drums of grade-B grease down to Slipway Four yesterday afternoon."

MacNair paused, his hammer hovering over a drift-pin. He squinted at Arthur through bloodshot eyes that had spent too many years looking at the glare of oxy-acetylene torches. "And what’s that to you, young Arthur? Since when did you become the clerk of works for the slipways?"

"I was down there with Walter this morning," Arthur said, keeping his voice low so it wouldn't carry over the racket of a pneumatic riveter working further down the keel. "The tracks are bone dry. There’s a red crust on them. It’s pitted the steel. If we launch the Sovereign on those guides, she’ll stick."

MacNair let out a short, bark-like laugh that ended in a wet cough. He drove the drift-pin into a bolt hole with three rapid, rhythmic blows that set the staging vibrating under Arthur’s boots. "Stick? The Sovereign? Lad, that tub has got more problems than a dry track. She’s been sitting on that slipway since the day they signed the armistice, and if you ask me, she’ll still be there when you’re drawing your pension. The directors only keep her there so they can point her out to the inspectors from London and claim they’re still building merchant tonnage."

"But the grease was delivered," Arthur persisted. "Four drums. That’s enough to coat the whole run twice over. Where did it go?"

MacNair stopped again, his face hardening. The easy, rough humor was gone, replaced by the guarded look that Arthur had seen on every older man in the yard whenever the conversation strayed from the daily grind of the plating. MacNair leaned in close, the smell of stale stout and peppermint on his breath.

"You listen to me, Arthur Pringle," MacNair said, his voice dropping below the roar of the yard. "Your brother Tommy was a good lad. He was the best loftsman this yard had seen in twenty years, and we all took a piece of the grief when he went down with the Arandora Star. But you aren’t Tommy. You’re an apprentice who hasn't even finished his third year. You don't ask where the stores go, and you don't go poking your nose into Miller’s business. Miller’s got friends in the main office—friends who wear clean collars and don't like boys who ask questions about grease."

"My brother didn't keep his mouth shut when the plates on the Argus were short-measured," Arthur said, his jaw tightening.

"And where did that get him?" MacNair snapped, pointing a thick, scarred finger at Arthur’s chest. "He got himself transferred to the merchant pool, didn't he? Sent out on the first coal-burner that had a date with a torpedo in the Western Approaches. Is that what you want? To go down in the cold water because you couldn't keep your eyes on your own hammer?"

The words hit Arthur like a cold bucket of harbor water. The memory of the telegram arriving at the terrace house in Nelson Street was still sharp—the yellow paper, his mother’s sudden, dry-eyed silence that had lasted for weeks, and the way Tommy’s room had been left exactly as it was, his slide-rule still sitting on the small table by the window.

Arthur didn't answer. He took a cold-chisel from his pocket and began cleaning the rust from around the bolt hole MacNair had just cleared. The steel was cold and stubborn, resisting the bite of his tool. He worked with a furious, silent energy, driving the chisel with precise, heavy blows of his hand-hammer, his mind turning over MacNair’s words.

The yard was full of ghosts. Not just the men who had been lost at sea, like Tommy, but the ships themselves. The Sovereign was the largest of them—a ten-thousand-ton cargo liner that had been laid down under a wartime contract, her frames erected in a hurry when the German submarines were sinking hulls faster than the Clyde and the Tyne could replace them. But when the war ended, the urgency had evaporated, leaving her a rusted skeleton on Slipway Four, her plates only half-pinned, her empty holds collecting rainwater and dead gulls.

Yet, over the last few weeks, something had changed. Men had been moved off the repairs—the small coasters and trawlers that kept the yard’s accounts in the black—and sent over to the Sovereign. But they weren't working on the upper decks or the accommodation blocks. They were working down in the double-bottoms, in the dark, cramped spaces where the fuel tanks and the ballast lines ran.

Arthur had seen them coming off the night shift, their faces grey with fatigue, their overalls soaked not with the usual black fuel oil, but with a strange, sweet-smelling compound that looked like yellow wax.

By midday, the rain had arrived, a driving, slate-grey downpour that came off the salt marshes and turned the yard into a bog of black mud and coal-dust slurry. The whistle blew for the dinner hour, a long, mournful hoot that was answered by the sirens of the locomotives shunting coal wagons down at the railway wharf.

Arthur climbed down from the staging, his hands numb with cold, his boots heavy with wet clay. Instead of heading for the canteen, where the air would be thick with the steam of wet wool and the smell of boiled cabbage, he walked toward the old mold loft—the vast, timber-floored building where the lines of every ship built at Wyre Haven were laid out full-size in chalk.

The loft was usually empty during the dinner hour, the loftsmen having gone to the pub outside the gates or down to the boiler house to warm their tin boxes of sandwiches. It was a quiet place, smelling of dry pine shavings and linseed oil, the high wooden rafters creaking in the wind like the ribs of an old sailing ship.

Arthur let himself in through the small wicket door in the heavy bay gates. The floor was a vast expanse of blackened timber, marked with a confusing maze of white, red, and yellow lines—the frames, waterlines, and buttocks of a dozen different designs. To an outsider, it looked like the scribbling of a madman, but to Arthur, it was a map. He could read the curves, tracing the rise of a bow or the run of a stern with his eye.

He walked to the far end of the loft, where the drawings for the Sovereign were stored in long, zinc-lined drawers to keep them from the damp. The drawers were heavy, smelling of vinegar and old paper.

He pulled out the drawer marked Hull 104—Sovereign—Lines and Scantlings.

The blueprints were large, stiff sheets of blue paper with white lines, their corners frayed and dirty from the thumbs of the shipwrights. Arthur spread the first sheet out on the layout table, using a couple of iron weights to hold down the curling edges.

It was the midship section, showing the massive longitudinal girders that gave the vessel her strength. Arthur’s eyes ran down the columns of figures—the plate thicknesses, the rivet spacing, the weight calculations. Everything looked standard, the solid, uninspired design of a Ministry-type cargo boat built to carry coal or grain across the Atlantic.

But as he turned to the next sheet—the arrangement of the double-bottom tanks—his hand stopped.

The drawing had been altered. Not with the usual neat red-ink corrections made by the drawing office clerks, but with a series of heavy, black-pencil lines that had been drawn over the original white lines. A series of auxiliary pipes had been added, running from the deep ballast tanks under the engine room through to the forward holds.

Beside the modifications, there was a small, neat stamp: Approved for Installation—Special Survey Reconstruction.

The date on the stamp was October 14th, 1945. Three months after the war had ended.

Arthur leaned closer, his breath frosting in the cold air of the loft. The pipes didn't make sense. In a standard cargo vessel, the ballast lines were designed to pump seawater in and out of the double-bottoms to keep the ship stable when she was running empty. But these new lines were small, too small for heavy ballast water. They looked like fuel lines, or perhaps chemical lines, designed to handle something much thinner than heavy marine oil.

And they led to a series of void spaces—cofferdams that had been created by adding extra watertight bulkheads in the cargo holds. It was a massive waste of cargo space, something no shipowner would tolerate in a peacetime vessel when every cubic foot of hold space meant profit.

"Looking for something, Arthur?"

The voice was quiet, but in the silence of the empty loft, it sounded like a hammer blow.

Arthur spun round, his hand instinctively covering the section of the blueprint he had been studying.

Standing at the top of the stairs that led up from the ground floor was Mr. Sterling. The assistant managing director was wearing a dark blue overcoat with a velvet collar, his leather gloves held in one hand. He had a cigarette in a silver holder, the blue smoke drifting up toward the high rafters.

"Mr. Sterling," Arthur stammered, his face turning hot. "I... I was just looking for the frame spacings for the timber-carrier. MacNair wanted to check the deck-plate alignment."

Sterling walked slowly across the wide timber floor, his leather-soled shoes making a soft, dry tapping sound that was very different from the heavy clop of Walter’s boot or the crunch of Arthur’s clogs. He stopped at the edge of the table, looking down at the blue sheet.

"This isn't the timber-carrier, Arthur," Sterling said, his voice mild, almost conversational. "This is Hull 104. The Sovereign."

"Yes, sir," Arthur said, his throat dry. "I... I pulled the wrong drawer. They’re next to each other."

Sterling didn't look angry. He reached out with a gloved finger and tapped the drawing, right on the spot where the black-pencil alterations had been made. "An interesting vessel, the Sovereign. A testament to what this yard can do under difficult circumstances. She was built to survive, Arthur. Built to take a torpedo and keep her cargo dry."

"The alterations, sir," Arthur said, the words slipping out before he could stop them. "The extra bulkheads. They aren't in the original specification. They take up nearly twenty percent of the lower hold space."

Sterling took a slow drag from his cigarette, the tip glowing a bright, angry orange in the grey light of the loft. He blew the smoke toward the ceiling, watching it curl around the timber beams.

"A shipyard is a living thing, Arthur," Sterling said. "It must adapt to the times. The war may be over, but the world is still a dangerous place. We are building for the future now. New materials, new methods. Some of those methods require... adjustments. The Sovereign is a prototype of sorts. A vessel designed for special service."

"What kind of service?"

Sterling’s eyes shifted from the drawing to Arthur’s face. They were cold, grey eyes, the color of the river on a rainy morning, showing no more warmth than the steel plates down in the drydock.

"The kind of service that doesn't concern an apprentice shipwright," Sterling said softly. "Your brother was a man who asked a great many questions, Arthur. He was very interested in drawings. He spent a lot of time in this loft, looking at things that didn't appear on the weekly work sheets."

Arthur felt a sudden tightness in his chest. "Tommy? What did he find?"

"He found that he was more suited to the sea than the shore," Sterling said, his tone perfectly flat, devoid of any sympathy. "He wanted to see how the ships behaved in deep water. It was a pity about his vessel. A great loss to the yard. We had hoped he would return to us after the war."

Sterling reached down, took the edge of the blueprint, and began folding it with slow, neat movements. "You have three months left on your third year, Arthur. If you work hard, and if you keep your mind on the work that is assigned to you, there is no reason why you shouldn't receive your journey lines when your time is up. The yard needs good shipwrights. It does not need amateur detectives."

He slid the folded drawing back into the zinc drawer and pushed it shut with a firm, metallic click.

"Go and get your dinner, Arthur," Sterling said, turning back toward the stairs. "The rain is clearing, and I believe MacNair is waiting for those deck plates."

Arthur stood by the empty table, his hands trembling slightly in his pockets. He looked at the closed drawer, then at the retreating back of the assistant managing director.

The warning had been clear enough. It was the same warning Walter had given him by the slipway, and the same warning MacNair had delivered on the staging. But there was something in Sterling’s voice—a cold, calculated certainty—that made Arthur’s stomach turn.

He walked out of the loft and down into the yard. The rain had indeed stopped, leaving the ground slick with wet coal-dust and oil. The men were drifting back from the canteen, their jackets steaming, their faces grim as they faced the afternoon shift.

Arthur didn't go to the canteen. He walked toward the boundary wall, where a narrow alley ran between the back of the engine shops and the high brick wall that separated the shipyard from the town.

It was a neglected part of the yard, filled with piles of scrap iron, old boiler tubes, and rusted plates that had been rejected by the inspectors. The ground was soft and marshy, the water standing in deep, oily puddles that reflected the grey sky.

As he rounded the corner of the engine shop, he saw something that made him pull back into the shadow of a stack of angle-iron.

A small hand-trolley was parked next to the back door of the paint store—a low, concrete building where the highly flammable thinners and red-lead paints were kept under lock and key.

On the trolley were four large iron drums.

Arthur crept closer, his boots making no sound on the wet earth. He reached the trolley and looked at the labels on the drums. They were standard five-gallon containers, their tops sealed with heavy lead caps.

But the labels had been defaced. The words Maintenance Grease, Grade B had been crossed out with a thick smear of black paint. Above them, someone had written in crude, hurried chalk:

Waste Acid—For Disposal.

Arthur reached out and touched the side of one of the drums. It was warm—not hot, but carrying that faint, chemical heat that comes from a reaction inside the metal. He leaned down and sniffed the small brass vent-plug on the top of the drum.

It didn't smell like grease. It didn't smell like oil.

It smelled of sulfur—the same sour, rotten-egg stench that he had scraped from the steel tracks of Slipway Four that very morning.

He knew then that Hector hadn't lied. The grease had been delivered. But it had never reached the tracks. Someone had swapped the drums, or perhaps used the grease containers to store something else entirely—something that was being used to destroy the slipway under the cover of the morning tide.

Arthur pulled out Tommy’s black oilskin pocketbook. His fingers were cold, the pencil slipping twice before he could get a firm grip.

He turned to a fresh page and began to write.

The grease from the store wasn't grease. It was acid. Miller took it. Sterling knows about the drawings. Tommy knew too.

As he closed the book, he heard the sound of footsteps coming from the other side of the paint store—the slow, rhythmic clink-clop of Walter Vance’s iron-shod boot.

Arthur didn't wait to be seen. He slipped back into the shadow of the engine shop, his heart hammering against his ribs like a loose piston, and began the long walk back to the timber-carrier, where the cold steel and the heavy hammers were waiting for him.
