Read Chapter 25: The Missing Person Revealed

The bone dagger felt heavier than it should, its carved grip slick against Élodie’s palm. Lucien leaned against her, his breathing ragged, his legs barely carrying him. The catacomb passage narrowed ahead, walls of stacked skulls and femurs glinting in the faint light of her lantern.

“Two more turns,” Lucien whispered. “There’s a grate—leads to the sewer line under the Rue de Sèvres.”

She nodded, pulling his arm tighter across her shoulders. Her own legs ached. The inn, Ashworth, all of it felt a world away. Behind them, the tunnel breathed—a low draft of stale air that carried the distant clink of metal.

Boots.

Lucien stiffened. “They found us.”

“How many?”

“More than we can fight.”

Élodie killed the lantern. Darkness swallowed them, thick as wool. She pressed Lucien against the wall, hand over his mouth, listening. The footsteps grew louder. Two men, maybe three, moving fast. A voice cut through the black—thin, familiar, like vinegar on a wound.

“Mademoiselle Marchand. I know you can hear me.”

Lefèvre.

“You’ve been a thorn in my side since the moment you returned to Paris,” he called, his footsteps echoing. “I gave you every chance to stay out of my affairs. I even killed your husband for you—saved you the trouble of a slow, public execution.”

The words struck her like a physical blow. Beside her, Lucien’s breath caught.

“Mathieu was never going to be a good husband to you, Élodie,” Lefèvre continued, closer now. “He liked to talk. He found a ledger I’d mislaid, and he thought he could barter it back for his freedom. Imagine. A lowly clerk trying to out-negotiate the Prefect of Police.”

Élodie’s blood ran cold. She felt for the small bone-shaped dagger in her sleeve, her fingers closing around its grip.

“I drowned him in the Seine,” Lefèvre said, almost cheerfully. “Had his papers altered to look like a skirmish at the front. Simple. Clean. It’s a shame you made this so complicated.”

She heard him stop. Ten paces away, at most. A match scraped, and a lantern flared, blinding her. She squinted against the light.

Lefèvre stood in the tunnel mouth flanked by two gendarmes. His face was pale, neat, smiling. He held Mathieu’s blue watch in one hand—her husband’s watch.

“Where did you get that?” she demanded.

“Your spy brought it to me,” Lefèvre said. He pocketed it. “He thought he was buying his way out. I let him believe that until the moment I put a bullet in his arm and sent him running back to you. Every move he makes, every word he whispers—I’ve known all along.”

Élodie’s throat closed. Ashworth. He’d seen her hidden confession in the watch and delivered it—she understood now. Lefèvre had controlled everything. The wound. The chase. Even the near-kiss in the dark had been part of his game.

“Secure them,” Lefèvre said.

The gendarmes rushed forward. Élodie raised the bone dagger, but Lucien was too weak to resist, collapsing to his knees. In that instant, she hesitated—and it was enough. A heavy hand caught her wrist, twisting until the dagger clattered to the limestone floor.

They bound her hands behind her back with coarse rope. Lefèvre approached, studying her face in the lamplight.

“You look like him, you know,” he said. “Your husband. That stubborn little jaw.”

“If you’ve hurt Ashworth—”

“Ashworth is dying in your cellar as we speak.” Lefèvre smiled. “And when he’s found, dead, in the home of a known English spy, I will have everything I need to hang your reputation out to dry. You’ll be remembered as a traitor’s whore. Your father’s name—ruined.”

Élodie spat at him. Lefèvre wiped his cheek with a handkerchief, unhurried.

“Take her to the sealed chamber,” he ordered. “I have a ledger to retrieve, and I want her to see exactly what she failed to find.”

They dragged her through the tunnels, Lucien stumbling behind. The catacombs turned, walls of stacked bones giving way to rough limestone and old brick. Deeper. Colder. At last, they reached a door of black iron, its face riveted with human vertebrae arranged in a pattern. In its center, a lock shaped like a human hand gaped open, its finger joints forming tumblers.

Lefèvre pulled a chain from his coat. On it dangled a single, desiccated fingerbone. He inserted it into the lock. The mechanism clicked and whined, and the door swung inward.

The chamber beyond was small and dry. Shelves lined the walls, laden with ledgers, satchels, and paper bundles sealed with wax. At a desk in the corner sat a brass lamp and a stack of correspondence. Lefèvre’s treasury.

“Here,” he said, gesturing with the lantern. “Twenty years of service to this city. Proof of every bribe, every blackmail, every secret I’ve bought and sold.”

He walked to a shelf and pulled down a leather-bound ledger with the imperial eagle embossed on its cover. “This is what your husband saw. This is what he died for. And now you will die for it too, regretting every choice that led you to this room.”

The gendarmes threw Élodie against the far wall. Rough hands wrapped rope around her wrists again, tighter, this time binding her to an iron ring set in the stone. They did the same to Lucien, who hung limp, his head drooped.

Lefèvre turned to leave. Then he paused, glanced back.

“I’ll kill the Englishman myself,” he said. “A courtesy, for how well he served me. And I’ll send Marie to join her husband in the river—a family reunion.”

He laughed. The door began to swing shut.

Élodie’s eyes darted around the chamber. Shelves. Ledgers. A low ceiling. The walls were old brick, crumbling in places. Above the door, a thick slab of limestone tilted slightly—part of the catacombs’ ancient architecture. Near her feet, a loose bone lay half-embedded in the mortar. A femur, long and brittle.

She shifted, testing the rope around her wrists. It bit deep but gave slightly. Her fingers brushed her palm. She still had the small fingerbone she’d taken from Lefèvre’s satchel—hidden in the seam of her sleeve, smaller than the dagger, easy to miss.

Lefèvre’s lantern retreated down the tunnel. The door hovered at the jamb.

The loose bone above the door trembled. A draft. This chamber wasn’t safe—the brick was failing. If that slab fell, it could seal them in forever. Or could bring the whole ceiling down on Lefèvre’s head.

Élodie twisted her wrists again. No give.

She worked the fingerbone from her sleeve with her opposite hand. It was tiny, too blunt to cut rope. But she didn’t need to cut it. She just needed to reach it.

She stretched her fingers toward the rope. Her wrists burned. Sweat slicked her palms. She managed to wedge the fingerbone between the rope and her wrist, twisting it against the fibers just enough—

The door slammed shut. The chamber plunged into darkness.

Somewhere in the tunnel, Lefèvre laughed, echoing and fading. She heard Lucien’s weak cough. The sound of water dripping. And above her, the faint grind of shifting stone.

The slab above the door was moving.

Élodie sawed the fingerbone against the rope, silent, frantic. A small piece of the ceiling crumbled and dropped, striking her shoulder. The grinding grew louder. The slab tilted.

“Wake up, Lucien,” she whispered, still sawing. “Wake up.”

The rope frayed. One strand. Two.

The ceiling groaned.
