Read Chapter 10: Under the Opera House

The pistol shot cracked against stone as the police inspector’s boot caught the edge of the grating. Juliette’s hand found mine, rough and insistent, and pulled me down through a gap in the cobblestones before I could think. The grate slammed shut above us, and for a heartbeat, the only light was a sliver of gaslamp through the iron teeth.

“Move,” she hissed.

I moved. The sewer tunnel opened into a low brick archway, slick with lime and runoff, the stench of Parisian filth pressing against my throat. Behind us, boots hammered on stone, and a voice shouted orders to circle around. They knew the sewers. We did not.

“This way,” I said, tugging her left where the brick turned older, rough-hewn, the mortar crumbling like dry bread. The sound of pursuit faded, replaced by the drip of water and the distant rumble of a Métro that did not yet exist. Paris was a corpse above, but below, it was still alive, breathing through its old bones.

We ran until my lungs burned, until the tunnel opened into a chamber that was not meant for waste or water. The walls here were dressed stone, carved with niches and faded frescoes, the kind of work that belonged in a cathedral, not beneath a drainage pipe. A faint smell hung in the air, not sewage but candle wax and dust, old velvet, and something else. Something metallic.

Juliette slowed, her fingers brushing the wall. She stopped at a section where the stone seemed newer, a patchwork repair, and traced a seam with her nail. “This shouldn’t be here,” she said. “The original cellars of the opera house. They walled them off when they built the new foundation.”

“You know this place.”

“I know the old maps.” She pressed two stones at once, and something clicked. A panel swung inward, silent on hidden hinges, revealing a narrow stair descending into darkness.

Behind us, a shout echoed. Closer.

I stepped through the opening first, Juliette close behind, and the panel swung shut of its own accord, sealing us in blackness absolute. She struck a match, and its flare showed a narrow shaft, the steps worn smooth by centuries of feet, and at the bottom, a door half ajar, spilling lamplight.

That metallic smell grew stronger.

We crept down, the match burning low, and pushed the door fully open. The chamber beyond was round, vaulted like a tomb, and in its center stood a single wooden table and a chair. On the chair sat a man, or what remained of one. His hands were bound behind the chair’s back, his head fallen forward, and the front of his coat was dark and stiff with dried blood.

Juliette made a sound, half breath, half choke. “No.”

“You know him?”

She stepped closer, slowly, and lifted the man’s chin with two fingers. His face was pale, waxen, the eyes open and empty. A face I had never seen, but one she clearly knew. “He is the agent,” she said. “Lucien’s contact. The last name on the list.”

A thought turned in my gut like a knife. “The Prussians found him first.”

“No.” She lowered her hand and pointed at his chest. The wound was a single, precise puncture between two ribs. “This was not an execution. This was an interrogation gone wrong, or a message. Prisoners are shot. Traitors are stabbed.”

I looked at the dead man. His pocket bulged, a crease of paper visible. The match sputtered. I stepped forward, carefully, and pulled out a folded letter, stained with his blood. Juliette struck another match as I opened it.

The hand was tight, precise, the hand of a clerk or a soldier trained in reports. It was addressed to no one, but the wording was unmistakable.

…the necessity of our arrangement has ended. The French envoy is dead, and his terms with him. The remaining diplomatic channels will be closed by tomorrow’s demonstration. The balloon pilot is known to us, but he carries nothing of value now. It is over. Do not write again. Burn this as you were told. Understand that if this falls into the wrong hands, I will deny everything. The name I have given you is worth more than your life, and mine is worth more than Paris.

It was signed with a single letter: D.

I read it twice. The implication settled in my chest like cold water. This was not the handwriting of a Prussian officer. This was the hand of a man who wrote in French, who spoke of closing diplomatic channels with a cop’s precision, who knew my name and my mission and what I carried.

“D,” I said. “Which of your generals begins with D?”

Juliette’s face, caught in the matchlight, went very still. “Delacroix,” she said. “Captain Delacroix is in charge of the city’s defense. But he is a captain. The letter says high-ranking. Which Delacroix have you met?”

I had not. I had only heard the name, barked through a chain of command that ran from the army to the police to the préfecture. But a man like that, with a rank high enough to close streets, to order arrests, to place soldiers around a balloon with a detonator in its cargo…

“General Delacroix,” I said. “There is a general. He commands the left bank defenses.”

Juliette shook her head slowly. “The general is a decorated soldier. He gave a speech at the Palais d’Industrie. He lost a son at Sedan. He would never—”

“He lost a son who the Prussians could have taken alive,” I said. “What better cover for a traitor than a father who grieves?”

She had no answer. Her match burned her fingers and she dropped it with a hiss, leaving us in the dark with the dead agent and that letter, now creased in my fist.

Something stirred in the shadows beyond the door. Not rats. I heard the careful step of a boot on stone, and the faint jingle of a revolver’s chain.

“They found the panel,” I said. I grabbed Juliette’s arm and pulled her to the far side of the chamber, where another door, smaller, half-hidden by a tapestry rotted with damp, promised a way out. I hauled it open, revealing a crawlspace that slanted upward, cold air breathing from its throat.

We ducked inside. The space was narrow, barely wide enough for my shoulders, and I had to crawl on elbows and knees, the stone scraping skin through wool. Behind us, the sound of men entering the chamber, voices low, and then one sharp command.

“Search the walls. He knows the crawlspaces.”

He. Not they. A man who tracked us, who knew we were here, who called me by a name I had not given.

I did not look back. I crawled, the letter gritted between my teeth, tasting the dead man’s blood on the paper. The air turned colder, the stone changed to cut limestone, and then the crawlspace opened into sudden space, and I tumbled forward onto a hard floor.

We were under the opera house proper. Overhead, I could hear it, faint and muffled through the floorboards: the massed voice of a crowd, singing. A funeral hymn. The city was burying someone important, or preparing to die itself.

Juliette crawled out behind me, breathing hard. She looked at the letter. “What do we do with this?”

“We deliver it,” I said. “To the only man above Delacroix who can act on it. Rothschild knows the military hierarchy. He has channels.”

She stared at me. “The banker who is blackmailing you?”

“The same,” I said. “The man who wants me to carry his detonator to Brussels also has the ear of the government. If I walk into his office with proof that a general is selling the city to the Prussians, he will listen. And if he does not, I will tell him his parcel is the only thing keeping me quiet, and I will tell his government everything.”

The singing above swelled to a crescendo. I pressed the letter flat against my thigh, the blood still damp, and made my way toward a stairwell that led up, toward light, toward the risk of the street.

But behind me, in the crawlspace, I heard the scrape of a match, and a voice I knew from the safehouse. The voice of the Prussian impostor, the man who had worn my brother’s handwriting as easily as a coat.

“Étienne,” he called softly. “It is good to see you alive.”

I ran.
