Read Chapter 10: The Foundry Fire

The coal-oil lamp guttered on his workbench, and Elias didn't look up until the smell of smoke reached him through the scent of solder and grease. Not the familiar tang of his forge. Something greener, sharper — like lamp oil burning with a chemical undercurrent.

He straightened, listening. The workshop was quiet, but beneath the hiss of the boiler he heard a crackle that did not belong. Wood. Dry timber, feeding.

The back wall of his hidden lab glowed orange.

Elias moved before thought caught up. He snatched the false memory panel from its clamps — the prototype meant for Sinjin — and shoved it into his canvas satchel. The real extraction device was dismantled in a lead-lined box beneath the floorboards; he dropped to his knees, pried up the loose plank, and hauled the box out with a wrench of his shoulder. Twelve seconds, maybe. The fire had already eaten through the inner wall, and the smoke was curling low along the ceiling, thick and black.

He grabbed for his mother's journal — the one book he'd kept from the house on Cinder Row — and stuffed it into the satchel on top of the panel. His notes on Ashworth's erasure mechanism were scattered across the drafting table: schematic pages for a weapon he'd barely begun to build. He hesitated. The fire had reached the table.

Not the notes. The *weapon* was in his head.

He ran.

The workshop's main door was already a curtain of flame — the fire had been set at both ends, deliberately. He doubled back through the lab, through the storage alcove, to the coal chute that fed the old heating grate. He'd widened it years ago as a boy's escape route, a game he'd played until his mother had caught him and said nothing, only looked at him with that flat, silencing stare.

He dropped the lead box down the chute first, then followed it, shoulders scraping against rusted iron, the satchel clutched to his chest. He fell two meters into the ash pit behind the workshop and rolled, landing on his side in a drift of cold cinders.

Behind him, the workshop roared.

He lay there a moment, coughing, watching the flames lick through the gaps in the boards above. The boiler would go soon. The stored gases would make it a spectacle — the whole block would turn out to watch, and someone would be standing among the crowd, smiling.

He dragged himself up and moved through the alleyways, away from the growing light and the distant cry of whistles. The lead box was a dead weight in his arms, but he did not set it down. Street lamps flickered through the smog as he walked, and the burn of smoke in his lungs gave way to the colder burn of calculation.

Who had known?

The hidden lab was not a secret he kept carelessly. The false storefront was meticulous — dust layered on the counter, tools arranged for a mundane mechanic's trade, bills from suppliers that had never sent goods. The laboratory itself was behind a false wall operated by a mechanism he'd built himself, with no visible handle or hinge. Only three people had ever seen the space beyond that wall.

Sinjin had sent men before, and they had found nothing. This was not a random torching from the underworld's enforcer — this was targeted. Surgical. Whoever had set the fire had known where the inner wall would be weakest, where the lamp oil was stored, which door was the actual exit and which was a decoy.

*Someone who knew the layout.*

Elias reached the river and stopped, leaning against the iron railing, the water black and sluggish below. He examined the lead box in his hands. It had survived. The satchel had survived. Everything else — his tools, his materials, his schematics, a decade's worth of notes and half-formed ideas — was ash.

He thought of everyone who had passed through that workshop in the past month. The street performer Mirella had only ever seen the front room. Cordelia Vane's clerk had never visited. Ashworth knew where the workshop was, but he'd never seen inside — Elias had been certain of that, had watched the man's eyes the whole time at the party.

Brother Aldous had stood in the doorway of the front room and spoken of fire.

Elias closed his eyes. The preacher's warning had been a threat, not a prediction — he had said *fire is coming* like a man delivering a message, not like a prophet reading one. But he had never crossed the threshold, never touched the false wall. He could not have known the lab's layout.

Sinjin knew. Sinjin had leverage, and Sinjin had links to Cordelia Vane, who had links to false offices and false names and questions she had no business asking. But Sinjin needed the extraction device. He wouldn't burn the only man who could build it — not unless he had another source, another inventor. Ashworth could erase memories, but extraction was Elias's own design, his own secret.

The only other man who had ever been inside that lab was Bert.

Bert, who worked two streets over, who had helped him haul the new boiler in three years ago, who had stood in the middle of the hidden space and whistled low and asked *what in the devil's name are you building down here, Eli?* Bert, who knew Elias had spent more money on metal than on rent, who knew the false wall didn't sit flush, who knew where the oil cans lived.

Bert, who had been oddly eager to talk about Elias's recent business with anyone who'd listen — the street urchin who delivered the gear had mentioned it, passing on a rumor from a pub where Bert drank.

Elias opened his eyes. The firelight painted the river red and orange, and somewhere behind him the workshop collapsed with a groan that reached him even at this distance.

He had nowhere to go. He had nothing left but a lead box, a satchel, and the name of a man he had called a friend.

The smog settled over the water like a shroud, and Elias began to walk toward Bert's street.
