Read Chapter 2: A Debt to the Cobbles

The summons came at the seventh bell, when the foundry whistle had long since died and the streetlamps coughed their sickly orange into the fog. Elias was bent over his bench, the memory-panel hidden beneath a loose floorboard, when a knock rattled his door. Not a polite knock. A rhythm. Three hard raps, then two soft ones.

He knew that pattern. He’d known it since he was fourteen, bleeding on a dockyard cobble, owing a man his life.

Elias wiped his hands on his leather apron and opened the door. The boy standing there was thin, pale, with eyes that looked too old for his face. One of Sinjin’s runners. He didn’t speak, just jerked his chin toward the alley, then vanished into the mist.

The walk felt longer than it should have. Lower Wren Street gave way to the tannery district, where the air hung thick with lime and rot, then down into the Cut—a warren of brick arches where the river’s damp seeped through everything. Sinjin kept his court in an old pump house, its iron wheel long rusted to stillness. Candles burned behind grimy windows, making the glass glow like dirty amber.

Two men flanked the door. Elias knew one by name—Hobbs, a bruiser with a shattered nose that had healed crooked. Hobbs didn’t speak. He just opened the door and nodded inward.

Sinjin sat in a wingback chair that must have cost more than Elias earned in a year, its velvet worn to thread at the arms. He was a small man, deceptively so, with the kind of stillness that made you think of a coiled spring. His fingers drummed on the chair arm as Elias entered.

“Elias Thorne.” The name rolled off his tongue like a stone. “Sit.”

Elias didn’t sit. Sinjin’s lips twitched, almost amused.

“Five years ago,” Sinjin said, “you were bleeding out beneath the Clockwork Bridge. Bullet in your gut. Gang of Whitefriars lads, if I recall, who didn’t take kindly to you fixing the wrong man’s boiler. I had you carried here. Had my own surgeon patch you up. Cost me three bottles of good whisky and a favor from a man I’d rather not owe.”

“I remember,” Elias said.

“Do you remember what you owe me?”

The silence stretched. Somewhere above, water dripped through pipes, a steady *plink-plink* that marked time like a slow heartbeat.

“Name it,” Elias said.

Sinjin smiled. It didn’t reach his eyes. He reached down beside his chair and lifted something wrapped in oilcloth—a cylindrical shape, maybe eighteen inches long. He set it on the table between them with a soft thunk. Unwrapped it slowly, deliberately.

It was a brass cylinder, ornate, with filigree etched along its sides. At one end, a funnel. At the other, a cluster of needle-thin probes arranged in a spiral. Elias’s stomach went cold.

“You recognize it,” Sinjin said.

“Modified resonating amplifier,” Elias said carefully. “Common enough for—” he stopped.

“For interrogation,” Sinjin finished. “Yes. But this one’s been… improved. By me. By a client who paid handsomely for the design. The problem is, it doesn’t work. Memory extraction used to be crude—torment, fear, whatever leaked out naturally. But this—” he tapped the filigree, “—this was supposed to pull memories out *clean*. Precise. A man’s secrets laid out like cards on a table. Except my tinkerer got himself killed in a factory accident, and the device sits useless because the calibration is wrong.”

Elias kept his face blank. His jaw was tight, his palms suddenly damp.

“I don’t work on that kind of thing,” he said.

“You don’t *want* to work on that kind of thing,” Sinjin corrected. “But you owe me.”

“I owe you my life. Not this.” Elias pointed at the cylinder. “This is—Sinjin, this is a machine for pulling the truth out of a man’s skull. Whatever the empire wants with it, they’ll use it on anyone they suspect. Laborers. Writers. Inventors. And they’ll call it *evidence*.”

“The empire doesn’t concern me. My client does.” Sinjin leaned forward. His voice dropped, softer now, more dangerous. “I didn’t keep you alive so you could grow a conscience, Thorne. I kept you alive because you’re the finest metal-smith on this river and I knew someday I’d need you. That day is today.”

“I can’t.”

“You *won’t*.”

The word hung in the air. Elias felt the weight of it, heavy as an anvil. He thought about the memory-panel hidden under his floorboard—the dead man’s plea, his own buried past leaking out like water through a hull. If Sinjin knew what Elias could really do, what he’d accidentally discovered, this brass cylinder would be the least of it.

“Tell me the debt is void,” Elias said quietly, “and I’ll walk away. No hard feelings. I’ll pay you back in coin over the next decade if you want. But I won’t build that.”

Sinjin was quiet for a long moment. He looked at Elias with the patience of a spider. Then he reached into his waistcoat pocket and produced a small, tarnished locket.

Elias’s breath caught in his throat.

“Recognize this?” Sinjin asked, dangling it by its chain. The silver caught the candlelight, glinting, familiar. Elias’s mother used to wear it. She’d worn it every day until she died.

“Where did you get that?” Elias’s voice came out rough.

“Your mother’s lodgings were cleared after she passed. Her effects went to auction to settle her debts. I had a man there. He bought this on my behalf.” Sinjin tilted the locket, opening it with a practiced thumb. Inside was a tiny etching, scratched onto a copper plate no larger than a fingernail. “Your sister, isn’t it? Lila. Lovely girl. Taken by the Foundling Office when you were both small. You remember that day, don’t you?”

Elias’s hands were shaking. He could see the etching from where he stood—a tiny face, a hint of braided hair, features blurred by age and crude craftsmanship. But he knew it. He’d always known it, even though he couldn’t remember her face clearly anymore. Memory was a strange thing: it faded at the edges, but the ache stayed sharp.

“You know why they took her,” Sinjin said softly. “You know what sort of records the Foundling Office keeps. Where they send children, what happens to them. And with the empire’s new registry laws, those records are about to become very hard to access. Very… private.”

Elias stared at him.

“Fix my machine,” Sinjin said, “and I’ll give you the locket. And the address of the institution where Lila was sent. You’ll have a chance to find her. Legitimately.”

The cylinder sat on the table between them. Cold brass. Cold promise.

“And if I refuse?” Elias managed.

Sinjin’s smile didn’t waver. “Then you’ll leave the locket with me. And I’ll send word north that a certain indentured girl—registered in the system as an orphan, subject to state reallocation—might be of interest to certain buyers. Ones who pay well for young hands. You understand.”

The words hit Elias like a fist to the chest.

He stood there, breathing hard, the weight of his life pressing down on him: his dead mother, his vanished sister, his secret on the floorboard, the dying man’s plea still etched in copper. And now this.

“I need time,” he said at last. “The calibration—I need to study it.”

Sinjin nodded, satisfied. “You have three days. Come Sunday, I expect you at my door with the device working. Or—” he gestured vaguely at the locket, still dangling from his fingers. “Well. You know.”

Elias turned and left without another word. The fog swallowed him the moment he stepped outside, cold against his sweat-damp skin. Behind him, the pump house door shut with a click like a lock turning.

In his pocket, his fingers brushed against the rough edge of a copper scrap—a piece of the accidental panel he’d carved two days ago. He could feel the ghost of its stored memory humming beneath his touch, like a heartbeat under stone.

He walked faster, the locket burning in his mind, and heard himself whisper to the fog:

“Lila.”
