The Brass Skeleton

Beneath Whitehall, the stone breathed with a cold rot. It was not air that filled the crypt but a mist soaked in Thames brine, pushed by the low tide through the lime joints. Steam hummed in the iron pipes set into the granite at a frequency so low it could not be heard: it was received in the molars, in the toenails pressed against the grating and in the pit of the stomach, where it reverberated like an untuned organ fifteen fathoms down. Silas Crane crouched motionless, his forehead resting against the black oak beam that held up the catafalque, waiting for the condensation to stop dripping on the back of his neck. In that cavity, shut off by three lead floodgates and tons of mud, any breath taken too deeply sounded like blasphemy.

Above his crown, a few spans from the waxed wood, rested the weight of the Empire. Or, more precisely, the most expensive illusion in Christendom: three hundred kilos of mourning cloth, fire-hardened Greenland whalebone and silver brocade wrapped around a queen who had been dead for four months. No one could come within three varas of the bed; a decree of the Holy Office forbade it, and the Mantle of State did the rest, smothering the death rattles of the machinery so that in the chamber above nothing could be heard but the solemn murmur of a sleeping majesty. Down below, in the artificer's pit, the artifice had no liturgy. It smelled of carbolic acid and whale grease: the synthetic lymph that oiled the connecting rods and turned any skin or paper it touched into pitch in under six minutes. Silas wore no gloves. Leather cost him a tenth of a second of touch, and touch was the only thing standing between his ministry salary and the scaffold.

The needle of the tachometer trembled on its brass dial. Sixty-eight beats. Sixty-nine. A dull stumble ran along the main shaft: the cadence dropped to fifty-six, bounced up to eighty-two and settled into a limping rattle that made the bronze crossheads screech. Upstairs, that imbalance would show as a convulsive tremor under the velvet of the royal breast, like the flutter of a crow trapped beneath a shroud. The Secret Ordinance allowed no explanations: the queen's chest had to rise and fall between sixty-two and seventy-four times a minute, and if the guards in the antechamber saw the velvet stray by more than four hertz, the black-wax valves would open and a salvo of superheated steam would flood the pit in under forty seconds.

Silas slid his fingers between the teeth of the differential, blind, among spatters of hot oil. His fingertips, hardened by two decades of tempering royal springs, recognized the fault at once: the left-flank compensating rod was not swinging on its agate bearing; it was knocking dry, jammed by the lime shed from the river coils. With his left hand he unhooked the ratchet wrench from his baldric; with his right he held the return strut so the cam would not jump its guide and burst the false ribcage. He fitted the spout of the oilcan between the articulated ribs. The lymph flowed over the rocker with a warm gurgle, overflowed the housing and ran between his knuckles, split open by brass burrs; the acid bit into the cuts with a burn that wrung a click from between his molars. He did not pull his hand away.

Through the iron beams that held up the catafalque, a dull pulse reached his pelvis. Footsteps. Two hobnailed soles stopping on the floorboards above, right at the edge of the three varas. The ministry guards were there, scrutinizing the swell of the velvet, waiting for the slightest hesitation to justify the purge.

"Turn, you heap of scrap," Silas muttered, swallowing the bile the phenol pushed up his throat.

He forced the adjusting lever to the left. The rod creaked and spat tiny sparks that died in the oily mud. His fingers slid on the wing nut; his blood mixed with the whale grease into a brown salve that smelled of rancid iron. Seventy-eight. Over the threshold. Above his neck, the black-wax pneumatic cylinder shuddered in its guide: the sentries were checking the surface gauge. Silas drove his thumb into the gear train and braked the cam at the cost of splitting his nail bed against the bronze teeth, while with his other hand he tightened the set screw until the steel shrieked.

The rocker found its course again. The needle crept back: seventy-four, seventy-one, sixty-six. A solemn rhythm, worthy of an empire's sleep. Upstairs, the boots pivoted on the oak and resumed their round toward the antechamber. Silas sank to his knees in the mud, his wounded hand pressed against his belly.

"It isn't compensating for the drag, lad."

Varley came out of the shadow of the side embrasure, dragging his lame leg, wrapped in greasy oilcloth, across the mud. Between his blackened fingers he held a pocket chronometer with a crazed enamel face. He had been Silas's master back when the queen still breathed on her own, and since she had stopped he went up to the bedchamber every morning in the habit of the royal apothecary, to anoint with camphor a body no one else was allowed to touch.

"Listen to it," he said. "It has a hanged man's syncope. Three tenths of a second late on every odd cycle."

"I tightened the set screw to the end of the thread. It read sixty-six before the guard finished the round."

"Sixty-six at rest, but the escapement is still biting false." The old man held a strip of vellum to the dorsal valve; two drops of lymph fell on the parchment and gnawed it away in a seething of brown bubbles. "If the mantle loses its rhythm in the next litany, they'll cook us before we reach the sluice."

Silas drew the entry pallet of the anchor out with his tweezers and turned it under the loupe. The edge was not worn. It was smooth and straight, with the fine parallel striations a watchmaker's file leaves behind.

"It isn't wear," he said. "Someone has filed the pallet."

Varley did not answer. Through the iron core of the main pillar came a vibration they both knew well: the procession of prelates was crossing the narthex. If the simulacrum faltered in the middle of the office, the mechanics would end up in a pit sealed with lead and nobody would ask about the file.

"They've put us down here to die with their doll," Silas murmured.

"Swallow your panic," Varley hissed, wedging his knuckles into the secondary gear. "The right arm's eccentric has just engaged. She signs today."

Beneath the mourning canopy, the whalebone frame creaked like the keel of a stranded whaler. Through the inspection slit, barely wider than two fingers, Silas saw the ministry's mahogany table and the document laid out on the crimson cloth. The queen's hand—a kidskin glove treated with lead salts to imitate the pallor of august old age—came down with a jerk. The rod of the pantograph was vibrating out of time, dragged along by the arrhythmia in the chest.

Then a joint gave. At the upper coupling of the bellows, the pressed gut split with a muffled snap, and a drop of yellow lubricant hung in the air for a fraction of a second before falling onto the official parchment. Silas put out his hand on a clockmaker's instinct, as if he could catch it from below.

The acid devoured the fibers of the document, dissolved the wax seals and left the text showing through beneath the trembling stroke of the mechanical pen. It was no customs ordinance. The words burned for an instant before turning to soot: Order of dispersal and summary condemnation for the stoker and stevedore gangs of the Lower Thames. Silas's own people. His guild brothers, sentenced to the furnaces for a conspiracy the ministry had built nut by nut.

Upstairs, heedless of the sore in the paper, the queen's gold fountain pen went on along its course, dragged the ink across the stain and signed the slaughter with a blind scrawl. A pneumatic click announced the vestibule floodgates opening: the smell of the acid would soon reach the halberdiers' noses. Silas looked for Varley's eyes in the gloom. In the old man's there was no craft left, only the certainty that the cage had just closed over their necks.
