The Silence of Lead

Varley reached the pit by the only way the Ordinance had forgotten to seal: the steam purge shaft, a duct that ran from the bowels of the crypt down to the tidal bed and that only old mechanics knew how to climb in reverse. Ada had shoved him into it with both hands when the sewer valves began closing behind them; she had stayed below, at the mouth that opened onto the river, with water up to her knees. Varley came out through the grating covered in silt, without his jar of camphor, his lame leg bleeding through the torn oilcloth.

"It goes at midnight," Silas told him before he could speak, and put the mud-caked cam into his hand.

Varley turned it under the coppery light of the gas jets. He saw the crest. For a long while he said nothing.

"Then the edict isn't for today," he murmured at last. "It's for tomorrow. A queen who dies at midnight in the hands of her mechanics, a stokers' conspiracy already signed and sealed in blood, and the Lord Protector weeping on the steps with the loan in his pocket. Vosper doesn't want the farce to last. He wants to choose how it ends."

The simulator was beating at sixty-four, hanging in its bronze cradle between the chains. Each stroke of the piston breathed out a warm vapor of tallow distilled in phenol, and beneath the dome of riveted plates the central rod spat an abnormal click: the teeth torn out that afternoon, the soft pallet, the anchor working with what it had left. Silas had tried to remove the cam. It was riveted to the crankshaft; tearing it out meant stopping the queen's chest, and stopping the queen's chest meant opening the valves.

"Cut the brine return," Varley said behind him. "The rocker jams on the downstroke. If you don't ease the gate, the back pressure will split the crosshead."

"If I touch the valve, the chest drops to fifty. They'll cook us before the needle gets back to sixty-two."

A dense hum ran along the beam that crowned the crypt and shook soot from the joints. It was not an order: it was the pre-purge sequence, a spaced knocking that came down through the pitch-sealed pipes. Upstairs, the bypass valves creaked as they took the first charge, a warning at three hundred degrees.

Silas fitted the punch into the slot of the escapement just as the rod reached the top of its arc. The impact of steel on bronze ran up his arm like a whiplash and split the pad of his thumb against the casing. He twisted the tool a quarter turn to the left and forced the spring to catch one more tooth. The simulator bucked on its chains and settled into a dry, tight cadence. Sixty-four, on the exact edge between the farce and the common grave.

From the walkway suspended over the vault, an angular silhouette cut across the beam of the carbide lamps. Hector Vosper did not come down. He rested the ivory knob of his cane on the main beam and struck three times; the impulse did not travel through the air but through the mass of iron, and burst in Silas's jaw. Then he spoke through the horn fitted to the lead pipe, his voice stripped of timbre by the mica diaphragm.

"Sixty-four. The ambassadors of the Hanseatic League have docked at the Water Gate three hours ahead of protocol. The chancellor wants the coffin raised upright in the Painted Hall before the tide goes out."

"If the bellows don't purge the condensation, the diaphragm will burst at the second genuflection," Silas replied without raising his head. "The anchor is three teeth short. Any diplomat who's awake will see the chest isn't breathing: it's convulsing."

"Then you'll hold the tension with your own tendons if the brass fails, artisan. If the cadence drops below sixty-one when the surgeons put the rod stethoscope to the mourning, the ballast gates will open. Ten feet of Thames mud."

"My lord." Silas raised the cam toward the walkway, knowing Vosper couldn't see it from there. "What time are they putting the stethoscope on her?"

There was a silence in the horn. Then Vosper's footsteps moving away along the grating, measured, without haste and without mercy, and the click of a last cartridge sealing the walkway hatch.

The bell of Whitehall began to strike twelve through the damp stone of the floor.

Silas counted the strokes with the punch held over the master ventricle. At the eighth, the crankshaft turned and the cam rose over the edge of the pinion like one tooth too many in a mouth. At the ninth, Varley hung on his arm.

"Leave it. Let her die. If you're holding her, they'll find you with your hands inside."

At the tenth, Silas drove the awl between the cam and the escape pinion. The brass groaned. Seventy, sixty-eight, sixty-five: the beat was bleeding out, and over the queen's breast the velvet must have been twisting in spasms, showing the edges of the whalebone to the surgeons of the State.

At the twelfth, physics made no bargains. The cam reached its tooth. A sliver of bronze flew off with the dry crack of a firing pin, the escapement leapt from its pivots and the mainspring, suddenly free of its two hundred pounds of torsion, lashed out blindly and pulverized the crown wheel. Splinters of red-hot brass and shards of whalebone flew out in a fan; one laid Silas's cheek open in a burning gash. The rods twisted on their shaft, devoured by their own inertia, and the machine that had kept a dead queen breathing for four months emptied itself onto the flagstones like a sack of smoking gears.

Upstairs, for the first time in four months, the queen's chest lay still.

The ballast sluices went off with a roar. From the upper gates came the thud of lead locking home, and a torrent of icy mud burst through the ventilation grilles. The mud was over Silas's shins before he let go of the awl.

He pushed Varley toward the purge shaft. The old man resisted for a second; then he wedged himself into the duct, bad leg first, and vanished downward, dragged by the suction. Silas stowed the cam in his leather pouch, fastened the buckle and threw himself in after him. The duct flayed his shoulders against the cast-iron ribs; the mud pushed at his back like a hand.

The outer grating burst under his weight and Silas fell on his side onto the frozen silt of the low shore. A dark lantern opened two varas away: Ada, waist-deep in the water, holding Varley by the collar of his habit. Silas coughed up blood and soot, swallowing the midnight fog, his hand closed over the pouch.

Behind them, muffled by ten varas of stone and lead, the bells of Whitehall began to toll. They were not ringing the alarm. They were ringing for the dead.
