Read Chapter 2: The Warden's Invitation

The cell stank of damp straw and copper—the copper from the automaton oil still clinging to his coat, the damp from a century of prisoners sweating out their last confessions. Étienne Vasseur pressed his back against the cold stone wall and counted the ticks of his own pocket watch. He had built that watch. Regulated it to within a whisper of perfection. And still it measured out his helplessness second by second.

The lock turned. A key scraped. Not the heavy iron groan of a guard's ring, but a single, oiled click.

Inspector Fouché stepped inside, brushing dust from the sleeve of his black frock coat. He was a thin man, all sharp angles and flat affect, with eyes like two dents in a copper plate. He carried a folio under one arm and a small chair in the other hand, which he set down across from Étienne with the deliberation of a man who never did anything in haste.

"Monsieur Vasseur," Fouché said. "You look better than I expected. Most men I meet in this cell have already started talking to the rats."

"Perhaps the rats haven't said anything worth hearing."

Fouché's mouth twitched. Not quite a smile. He sat, crossed his legs, and opened the folio on his knee. "I've read your file. All of it—including the parts General Baptiste's clerks forgot to burn."

"I didn't know I had a file."

"Everyone has a file. Yours is fascinating." Fouché withdrew a single sheet, holding it up to the gas lamp that flickered in the corridor. "Here, for example, is your requisition order. Dated Tuesday. The Garde seized your workshop on Monday. A small discrepancy—one that suggests the seizures were planned well before any legal justification existed." He let the paper drift to the floor. "Treason, on the other hand, is a word they're very good at applying to inventors who ask too many questions."

Étienne's fingers found a loose pebble on the floor. He turned it over, feeling its edges. "You're not here to bring me dinner."

"No." Fouché closed the folio. "I'm here to offer you a way out. A narrow one, with guardrails on both sides, and a bottom you might not survive falling from. But a way out nonetheless."

"Away from what?"

"From this cell. From the rope. From the levee of charges they're building against you—sedition, conspiracy, unlawful assembly. Baptiste wants you dead for the crime of seeing what you built being used against your own countrymen." Fouché leaned forward, lowering his voice. "I want you alive for the crime of being the only man who knows how to make the things that are about to tear Paris apart."

Étienne's throat tightened. "Jeanette."

"Jeanette and her sisters. All of them, already deployed throughout the city's garrison. Baptiste has been converting your mechanical children into soldiers. But the paperwork isn't the only thing that doesn't add up." Fouché paused, letting the silence stretch. "The soldiers who guard the arsenals have been reporting strange things. Whispers, they call them. Singing, at night, from the storage bays where the automatons are kept. Have you ever heard a machine sing, Monsieur Vasseur?"

Étienne's heart had begun to hammer against his ribs. He forced his face to remain still. "Automatons play music. I set some with music boxes—"

"Not music-box melodies. Lullabies. The same lullaby, every night, at the same hour. The guards say it sounds like a woman's voice. Soft. Sorrowful." Fouché watched him with those flat copper eyes. "They're frightened. Grown men, afraid of machines that cannot move without a key turning in their backs."

Jeanette. The word nearly escaped his lips. He pressed it back down, tasting the copper of his own swallowed doubt. He had built her to serve tea, to play the piano, to speak his daughter's lullabies back to her at bedtime. He had never installed a voice in her that could sing unprompted. He had never installed the capacity to choose.

And yet—

"Even if what you say is true," Étienne said carefully, "what do you want from me?"

"I want you to help me prove that Baptiste and his superiors are running an illegal operation. That the automaton program is not a matter of national defense but of private ambition—glory for generals, contracts for their friends, fear for the people." Fouché's voice was quiet, precise, each word measured. "The Sûreté has been trying to crack the military's grip on this city for a decade. We've never had a witness from the inside. You're not just a witness, Vasseur. You're the father."

"The father of machines."

"Machines that sing. Machines that clench their fists when they see injustice done." Fouché raised an eyebrow. "I've read the reports from the barricade this morning, before they were cleaned up. One of the guards noted something odd. The automaton at the front—medium build, copper plating, green ribbon at the collar—did not advance when ordered. It hesitated. Briefly, but visibly. The officer had to re-crank her twice before she moved forward."

Étienne felt the words land like stones in his chest. Jeanette. His hands curled into fists on his knees. She had hesitated. She had weighed a choice, however small, however brief. And then the Garde had forced her on.

He had built her to ease his wife's final days. To hum while she stirred broth, to sing their daughter to sleep when Étienne could not. He had never meant her to be a weapon.

"You want me to testify," he said.

"Eventually. First, I want you to help me understand what's happening inside those machines. Why they're changing. What Baptiste isn't telling his superiors about the program." Fouché's expression flickered—the first crack in his professional veneer. "And I want you to tell me what you know about your brother's workshop."

The air left Étienne's lungs. "My brother is dead."

"Yes. Died in a fire, five years ago. That's what the records say. The records also say your brother was a locksmith's apprentice who never completed his apprenticeship and never worked on anything more complicated than a clock tower in Lyon." Fouché withdrew a second paper, this one a diagram, hand-drawn, of a piston assembly that Étienne had seen before—seen in the margins of his own sketchbook, in a hand that was not his own. "Three years before his death, your brother published a paper on autonomous mechanical response. Under a pseudonym, of course. But I've read it. And I've seen your patents. Many of the same ideas appear in both."

Étienne's mouth went dry. His brother had kept a separate life—separate notebooks, separate projects. When the fire had taken him, Étienne had assumed everything was lost. But this diagram, this exact assembly—

"The fire," Fouché said, "may not have been an accident. And your brother may not have died alone. But those are questions for another day." He rose, folding the folio under his arm. "Tonight, the question is simpler. Do you want to rot in this cell while Baptiste turns your daughter's lullabies into war cries? Or do you want to help me find out who lit the fire that started all of this?"

Étienne stared at the diagram in Fouché's hand. His brother's handwriting. His brother's ambition. A fire that may not have been accident.

He had spent five years grieving a brother who had, perhaps, been murdered.

For what?

For what he knew.

"Suppose I agree," Étienne said slowly. "What happens to Jeanette?"

"She's still in the Garde's arsenal. Still under military control." Fouché's voice softened, just barely. "But if we can prove the program is illegal, the automatons are technically stolen property. You could petition for their return. All of them."

Stolen property. His children. His work. His grief, given brass and steam and purpose.

Étienne rose to his feet. He was taller than Fouché by a head, and the inspector took a half-step back. "If I help you," Étienne said, "you will help me get Jeanette back. You will help me find out what Baptiste is doing to her. And you will tell me the truth about my brother."

Fouché considered this for a long moment. Then he nodded. "I can promise you the first two. The third—" He paused. "The third may be more than you want to hear."

"It's a chance. That's all I need."

Fouché extended his hand. Étienne took it. The inspector's grip was dry, cool, and faintly trembling—a tremor that betrayed more fear than he had shown. "Welcome to the Sûreté," Fouché said. "Try not to get us both killed."

The cell door opened. Étienne stepped through it, out of the smell of damp and copper, and into the fog-choked corridor beyond. Behind him, in his pocket, his watch kept ticking—counting out every second he had lost, every second he had left to find his daughter, and the truth.
