The Dead of Night

Chapter summary

• Core event: Fumitaka caulks an illicit hull seam underwater in a flooded drydock and avoids a provost patrol before discovering the copper plate schematics specify a kinetic ram rather than a blockade runner.
• Continuation: First chapter of the volume.
• Closing hook: Fumitaka unrolls the broker's blueprint and realizes the lodestone placement and copper weight will turn the sloop into an acoustic battering ram aimed at the harbor floodgates.

Cold harbor water rose to Fumitaka's collarbones, smelling of dead crabs and coal smoke.

He gripped the iron caulking chisel with three scarred fingers and set its oiled felt collar against the weeping seam. Above him, sixty feet of oak planking groaned against the wooden shores. One slip of the iron mallet against stone would echo up the flooded granite slipway like a pistol shot, and the naval provosts on the high pier had ears trained for treason.

"Keep the pitch pot level," Fumitaka muttered into the dark.

Ten inches to his left, Genzo clutched the rim of the suspended brazier. The young apprentice was shivering so violently the chains rattled against the staging beam.

"The tide is creeping, master," Genzo whispered back, his breath coming in fast, ragged puffs. "The sea-ghouls come up with the high swell. My grandmother said if you taste bilge copper after midnight, your lungs turn to brine."

"That isn't copper," Fumitaka said without turning his head. "It's the tannery runoff from the upper canal. Stop shaking before you dump hot resin into my boots."

Fumitaka waited for the harbor swell to push against the lock gates. The deep surge created a low, vibrating groan through the drydock's granite floor. Exactly as the water surged, he struck the mallet against the felt-wrapped chisel head.

Thump.

The strike was dull, absorbed by the felt and smothered by the sloshing tide. Hot black pitch bit deep into the split oak. A thread of gray steam hissed into the black water around his chest. He reset the chisel, checked the grain with his thumb, and waited for the next surge.

Thump.

Four more strikes wedged the hemp oakum flush against the inner frame. The leak died to a trickle, then stopped entirely. In the quarantined port of Shiranami, unauthorized timber repairs carried a sentence on the high yardarms, but thirty iron chits from the broker Daigo would buy forged transit passes for Genzo and the girl Saki. An old shipwright's neck had very little market value anyway.

A sudden yellow glare cut across the dark ceiling of the slipway.

Genzo gasped and dropped his chin into his collar. "Lanterns on the east gangway."

Fumitaka reached up, clamped a scarred palm over Genzo's mouth, and shoved the boy's head down into the shadow of the keel. With his other hand, he caught the lip of the suspended brazier, pinching the charcoal glow under a wet slab of slate.

Heavy boots struck the stone quay twenty feet above them. The rhythm was brisk and regular: two provost marines in boiled leather, their iron-shod halberds clinking against belt buckles.

"Hold the beam," a hard voice barked from the pier edge.

The yellow lantern beam swept the black water, skimming the moss-slick granite blocks and the row of rotting support pilings. The light crawled across the sloop's starboard planks, illuminating patches of white barnacles and dark marine grime.

Fumitaka remained motionless in the hemp harness. The freezing salt water bit into his chest, but he kept his breathing slow and shallow through his nose. He had built three of the patrol barges currently docked at the naval citadel; he knew the blind spots beneath a sixty-foot keel better than the men holding the lanterns.

The light lingered on the fresh pitch patch for three seconds. To a trained naval inspector, the dark line was still wet. To a bored provost on the midnight watch, it looked like another streak of harbor filth.

"Nothing down there but dead eels," the second guard grunted. "Slipway Four has been condemned since the winter blockade began."

"Check the chain lock anyway," the first replied.

The footsteps moved off toward the outer capstan. The iron gate rattle faded into the constant, dull roar of the outer surf.

Fumitaka released Genzo's jaw and blew a slow breath into the mist. "Get the tallow cloth over the brazier. We climb up."

Genzo scrambled onto the damp wooden scaffolding with all the grace of a netted cod, his knees knocking against the cedar planks. Fumitaka pulled his own heavy frame out of the water, unhooking the sodden hemp harness. His joints ached with the deep, sour stiffness that twenty years in wet slipways gave a man.

They retreated into the dry recess beneath the inner quay wall, where a single oil lantern sat shielded inside an upturned nail keg. Fumitaka took the coarse rag Genzo handed him and wiped the salty grit from his forearms.

"We sealed the garboard strake," Genzo whispered, rubbing his knuckles near the lantern chimney. "That's what the broker paid for. We can take the chits and leave the port tomorrow."

"Daigo left the second half of the contract on the work chest," Fumitaka said.

He picked up the rolled sheet of oiled parchment weighted down by an iron square. He unrolled it across the top of an empty tar barrel, anchoring the curled edges with a pair of rusty calipers.

The parchment showed the vessel's lower hull profile, marked in crisp vermilion ink.

Fumitaka squinted at the measurements. His brow furrowed as he traced the ink lines down the spine of the deadwood.

"Master?" Genzo asked, leaning closer. "What is it? Did he short the timber dimensions?"

"Look at the copper cladding," Fumitaka said, his voice flat.

Genzo squinted at the draft. "Four-inch plates along the waterline. That's heavy for a sloop, but smugglers need speed against the naval cutters, don't they? The magnetic drag keeps the hull level in the rough rips."

"A blockade runner carries quarter-inch sheathing," Fumitaka said. "You taper it toward the bow so the hydro-magnetic resonance slips through the granite sea-veins without waking the bottom sensors. You want the hull to skim."

He tapped his calloused finger against the deadwood schematic.

"Daigo isn't asking for quarter-inch sheathing. He wants solid four-inch rolled copper bolted directly to the keel timber with iron dowels. And look at the drill recesses inside the deadwood."

Genzo blinked at the red dots clustered along the bow stem. "Lodestone wells? Why would anyone put twelve magnetized rods inside the forward timber?"

Fumitaka stared at the drawing. A cold weight settled in his belly that had nothing to do with the harbor water.

Twelve lodestone rods aligned with four-inch copper did not reflect acoustic waves to slip past the blockade. When submerged in salt water and struck by the correct horn frequency from the deck, that mass of copper would lock onto the submerged granite bedrock of the bay like an iron spike driven into an anvil. It would create a rigid, unyielding kinetic wedge of twenty thousand tons.

A vessel fitted like this could not turn. It could not outrun a patrol cutter. It had only one possible function: to be aimed at the massive stone hinges of Shiranami's sea-gates and driven forward until the entire harbor wall shattered under the impact.

"Master?" Genzo's voice went thin and fragile. "Who did we take this job from?"

Fumitaka rolled the parchment tightly and shoved it into the dry breast of his oilcloth coat.

"Pack the chisels," Fumitaka said. "We are going to find Daigo."

Chapter notes

• Hook of this chapter: Fumitaka discovers that the ship's copper and lodestone schematics are designed as a devastating kinetic ram against the harbor's sea-gates, not a smuggler's escape craft.
• Next chapter preview: Fumitaka confronts the broker Daigo on the stone piers to demand the truth and protect his apprentices.
• Foreshadowing: The hydro-magnetic resonance pattern on the keel is planted as a weapon intended to destroy Shiranami's floodgates.
