At four hours past midnight, the river March reached its total sky-high minimum. Down at the South Basin water-gate, the receding tide had exposed eight feet of slimy green granite wooden support posts, the mudflats stretching out into the darkness like the ribbed belly of a beached giant beast. The roaring tumult of the upper river had dwindled to a steady, hollow murmur echoing through the limestone water chutes.
Inside the uncoupling vault beneath the Hero Monument, the heat had dropped below freezing. The air was bone-dry and tasted of frost, ozone, and wet lime. Of the forty nested rings of static-electric copper coils that had once pulsed with stolen light, thirty-nine hung dark, cold, and dead, their liquid silver baths drained into iron carboys.
Tomas Reed sat upon an upturned ash nail-keg, his knees wrapped in a coarse horse-blanket against the piercing cellar chill. His left forearm ached with a deep, marrow-deep throb that made his fingers curl inward against the palm splint. He step by step massaged the scarred tendon line with his right thumb. He felt the tough, unbending gristle where Gerva’s stitches had held. In his lap rested the master route ledger, lit up by the steady yellow glow of Hester Quill’s horn lantern.
“Six hundred and ninety-five deposits are in lawful custody or on confirmed wagons,” Hester said. He ran her brass metal pen down the final thick parchment folio. “Only eighteen remain unaccounted for on this floor. Fourteen belong to the district keeper chests at White Steps and Fen Hollow, held back until the High Bridge roadway was cleared. Two belong to the cousins Jeda and Var in the western orchards. One belongs to Dalen Ross at the North Bell Tower. And the last... Is the eight-sided anchor at the base of the drain tube.”
Tomas looked down into the central pit. Suspended within the final, shuddering blue arc of current hung Oren Voss’s plate. Deposit Seven Hundred and Thirteen. The bronze was shivering in its socket. It shook in deep ring with the last leftover trickle of water passing through the main turbine.
Aven Lark climbed down the iron check ladder, his uncoupling tongs trailing a thick braided copper ground-line behind him. “The drain tube is at dead-stall, Tomas. The stone bypass is carrying nine-tenths of the river. The static-electric tension on Oren’s plate has dropped to sixty volts. We can pull the anchor without blowing the foundation ring.”
Nessa Vale stood at the foot of the ladder, her sound horn tucked into her oilskin coat. She held a pair of heavy rubberized lineman’s shears. “The low-tide window will hold for exactly ninety minutes before the sea begins to push the estuary back up the valley. If we’re going to close this ledger, every one of these eighteen records must be in its receiver’s hands before dawn.”
Tomas stood up from the upturned nail-keg. That let the coarse horse-blanket slide from his knees onto the dry timber staging. The ninety-minute margin left zero room for a misrouted cart or a disputed signed name at a garden gate. With his right hand, he drew the chalk-board schedule from beneath Hester Quill’s horn lantern and laid it across the top of the two leftover cedar chests. One branded with the white quarry-step mark of White Steps, the other with the crossed-reed glyph of Fen Hollow.
“Before we touch Oren Voss’s anchor in the pit, we clear the seventeen,” Tomas said, his voice echoing flatly off the thirty-nine dead copper rings hanging overhead in the freezing dark. “Why were these fourteen community plates held back on the lower rack when Ada Fen and Orrin Hale took their main wagons out at midnight, Master Lark?”
Aven Lark wiped his glasses on the hem of his wool smock, his breath pluming white in the sub-zero vault air. “Because those fourteen canisters were wired into the backup governor bridge on Tier Six,” the old artificer explained. He pointed with his padded copper tongs toward a cluster of fourteen small eight-sided sockets bolted directly beside the main intake butterfly-valve. “When Renn Tal built the automatic flood-governor in Year One, Holt’s mechanics tapped fourteen citizen plates—eight from Fen Hollow and six from White Steps—to hold the butterfly-valve open against the silt-pressure. If I had pulled those fourteen while the main pool head was still above twelve feet, the butterfly-valve would have slammed shut and burst the cast-iron intake collar before your western bypass took the load.”
“And now the intake pipe is dry to the lower doorstep,” Nessa Vale confirmed. She tapped the glass face of the liquid silver U-tube gauge mounted on the pier beside her shoulder. “Zero high-pressure head on the butterfly-valve. The iron leaf is resting on its own bronze stop-pins. You can strip the governor bridge in ten minutes without moving a drop of water.”
Tomas nodded to Sile Rook and young Jory, who stood waiting beside the padded timber hand-barrow at the foot of the stone ramp. “Aven, pull the fourteen governor plates now. Jory, as each canister comes off the tongs, check the serial notch against Hester’s list and pack it in dry oat-chaff. Sile, once those fourteen are sealed into the two cedar chests, you and Jory take the light spring-cart across High Bridge. Mara Flint’s masons have cleared the toll-plaza. So you have a clean trotting road straight to White Steps and the south polder dike.”
Sile Rook hefted his two-inch tall oak body-shield onto his back strap and tested the hemp rope-beckets of the Fen Hollow chest with one scarred hand. “And what about you, Tomas? You’re talking about walking four miles west to the orchard line for Jeda and Var. Then climbing eighty steps up the North Gate belfry for Dalen Ross, with your left wrist tied in a rag and ninety minutes on the tide-clock.”
“I’m taking you as far as the west orchard crossroads on the spring-cart before you turn south for the polders,” Tomas answered, adjusting the buckle of his ash-wood pack frame with his right hand so the main weight-band rode squarely over his right collarbone and hip-bone, leaving his braced left forearm free of the strap’s bite. “From the orchard shed back to the North Gate is three miles along the old canal towpath. I have walked that path in forty minutes with two hundredweight of wet laundry on my back. I can walk it in thirty with three bronze cylinders.”
While Aven Lark climbed onto the sixth-tier duckboard and began shearing the lead retention pins from the fourteen governor sockets—each twist producing only a faint, dying orange spark now that the main coils were drained—Hester Quill laid out the three single delivery slips for Deposits Seven Hundred and Ten, Seven Hundred and Eleven. Seven Hundred and Twelve.
“Pay close attention to the orchard receipt, Tomas,” Hester said. He handed him a waterproof zinc metal tube containing two notarized court attachments. “Deposits Seven Hundred and Ten and Seven Hundred and Eleven are both in the name of Kester Var, master wheelwright, payable jointly to his grandchildren Jeda and Var the Younger. They live beyond the town milestone in the unincorporated orchard tract. Because of that, the Guild of Wheelwrights has refused to recognize their residency for thirty-nine years. Both grandchildren must sign or set their marks to the same sheet in my presence to vest the back-pension. So I’m riding on the spring-cart with you.”
By the time the fourteenth governor canister clicked into the cedar chest and Jory drove the wooden dowels into the lid cleats, seventy-eight minutes remained before the turn of the estuary tide. Down in the central pit, only a single pale blue light still burned under the quartz glass. The solitary eight-sided plate of Oren Voss. It hummed softly to itself at the very bottom of the drained iron cage.
Mirelle Voss stood at the edge of the pit railing with her father’s cedar box tucked under her arm. She looked down at that last blue ember. “Go finish the seventeen, Tomas,” she said quietly, not taking her eyes from the quartz slit. “My father waited until the townspeople crossed the bridge before he laid his hands on the wheel in Year One. He wouldn’t let you pull his name out of the floor while three families on the road were still waiting for their receipts.”
Tomas closed the ledger with a quiet snap of its leather clasp. “Fourteen go into the Fen Hollow cart with Sile. I’ll take the orchard cousins and the bell tower. And when those seventeen are signed, we bring Oren’s plate to Mirelle.”
