Read Chapter 30: The Escape from the Hôtel de Ville

The stench hit them first—a wet, sour wall of it that made Céleste gag before they'd gone three steps into the tunnel mouth. Beneath the Hôtel de Ville, the sewers of Paris ran like black veins through the city's corpse, and Émile knew these passages better than he knew the faces of most men he'd photographed. Better than he wanted to.

"Ahead," he said, pulling Céleste by the wrist. "The branch at the Fontaine. Keep low."

Behind them, boots rang on stone. De Valois's men had found the grate quickly—too quickly, as if they'd known it existed. Maybe they did. Men who guarded the Hôtel de Ville knew every hole a rat could crawl through, and Émile was the rat tonight.

Céleste stumbled on the uneven footing, caught herself against the curved brick wall, and kept moving. Her pistol was still in her hand, wet with the spray of the tunnel's narrow channel. She hadn't fired it since the flash powder blinded de Valois. Émile didn't know if she'd fired it at all. He didn't ask.

"Which way?" she said.

"Left at the fork. The main collector runs under the Rue de Rivoli—too open. De Valois's men will know it. We want the old branches, the ones the engineers forgot."

Luc came up behind them. He'd been silent since the flash, since Céleste's pistol had carved a path through the guards' confusion and they'd fled down the service stairs into this reeking dark. His face was pale beneath the grime, his hands raw where they'd grabbed at the plate that Émile carried against his chest.

Émile shouldered through a narrow gap where the tunnel choked itself to half its width. Water rushed past his ankles, cold and carrying things he refused to identify by feel. He'd been in trenches in the war that had smelled better. But the dark was a friend tonight, and the sewers offered a hundred turnings where a man might vanish.

Boots behind them. Closer now.

"Two of them," Luc said quietly. "Maybe three."

Céleste glanced back at the sound. "They'll catch us in the open stretch before the Fontaine."

Émile stopped. He'd been thinking it too. The tunnel ahead opened into a long, straight collector where the water ran deep and the walls offered no cover. They'd be silhouettes against whatever dim light filtered through the grates above.

"Not through," he said. "Over."

He pointed to a rusted iron ladder that climbed the wall to a maintenance hatch—one of the old inspection points, sealed years ago when the city had redirected the flow. Émile had used it once, during the siege, to move plates between darkrooms without crossing the streets.

Céleste understood before he finished pointing. She holstered her pistol and started climbing. Luc followed, his movements stiff, the watch heavy in his pocket.

Émile came last, pausing to scrape mud from the rungs so the pursuit would lose seconds looking for their trail. The hatch was rusted shut, but he threw his shoulder against it once, twice, and the seal gave with a groan that echoed down the tunnel.

They spilled into an alley behind the Rue Saint-Antoine. Rain fell in a thin, miserable drizzle, washing the worst of the filth from their clothes. The streets around them were empty—the curfew kept good citizens indoors, and the Communards who walked at night walked with purpose, not pleasure.

"Where now?" Céleste said.

Luc was already looking east. His eyes had that far-off quality Émile recognized—the look of a man who'd spent too long in the dark and had begun to think in terms of exits.

"The eastern gates," Luc said. "Porte de Vincennes. The Prussians hold the perimeter there. They don't care about the plate—they care about the war. If I can slip through their lines, the plate goes with me."

Émile shook his head. "The plate stays with me."

Luc's face tightened. "Émile—"

"You heard the man in the tavern." Émile kept his voice low, but the heat bled through. "Moreau has your watch. He thinks he has your plate. He doesn't know you made a copy." He patted his coat where the two glass negatives lay wrapped in oilcloth. "I have both plates now. If you carry one, and de Valois's men take you, they'll take it. We split the burden, or we don't split at all."

Céleste looked between them. The rain darkened her hair, plastered it to her forehead. "He's right," she said. "One of us carrying everything is a single point of failure. But three of us moving together makes a pattern. De Valois's men will call ahead, trap us at the next crossing."

Luc was silent a long moment. Then he reached into his pocket and pulled out the watch—the heavy brass watch Jules had worn, that Moreau's men had taken and Luc had somehow recovered. He held it up, and in the dim light of a distant gas lamp, Émile saw that the face had been replaced. Not glass. Something black, filmed with age.

"It's not a clock," Luc said. "Not anymore."

He worked the winding stem, and the back of the watch swung open on a hinge Émile hadn't noticed. Inside, nested in a bed of felt, lay a third glass plate—slightly smaller than the others but unmistakably the same image. The massacre. The same composition, the same horror, captured from a slightly different angle.

Émile stared. "You had it all along."

"Moreau's men took the watch from my coat when they caught me at the printing shop. They found the plate I'd planted in my camera—the decoy. They thought the watch was Jules's memento." Luc's smile had no warmth. "Grief makes good cover."

"So the copy I found in the darkroom—"

"Was the copy. This is the original." Luc closed the watch, pressed it into Émile's palm. "Jules never carried a decoy. He carried the truth, and he died for it. But I made sure it would survive him."

Émile's hand closed around the watch. It was heavier than it looked, warm from Luc's pocket. He could feel the plate inside, fragile as a held breath.

Céleste broke the silence. "If Luc doesn't carry a plate, why does he go east alone?"

"Because he's the bait," Émile said slowly, understanding dawning. "Moreau's men know his face. They know he was photographed with the watch. If they see him moving east without a camera, without plates, they'll assume he's sent the plate ahead—or that he's the courier himself. They'll follow him, not us."

Luc nodded. "And you two go west, toward the river, and vanish. When the chase is on me, you find a darkroom and make your copies. Then the plate becomes useless as blackmail—too many originals, no proof which was first."

Émile looked at the watch in his palm. Three plates now sat in his possession, the false and the true, and the weight of them pressed against his ribs like a second heart.

"You'd walk into a trap knowing it's a trap?" Céleste asked Luc.

"I walked into one to get this watch back." He touched his coat where the wound had healed thin. "I can walk out of another."

Émile handed the watch back. "No. They'll search you. They'll find it."

Luc shook his head, already threading the watch chain through his buttonhole. "They'll search me at the gate, yes. And they'll find nothing. Because I won't have it." He looked at Émile with an expression that was almost gentle. "You'll follow at a distance. When the moment comes, you'll do what you do."

"Photograph it?"

"Bear witness." Luc clapped him on the shoulder. "You're the one who never lied with a camera,Émile. Don't start tonight."

He stepped east without another word. His boots made soft sounds against the wet cobblestones, then quieter, then gone.

Céleste stood close to Émile, watching the darkness where Luc had vanished. The rain fell harder now, washing the alley clean of their footprints.

"He'll be caught," she said quietly.

"Yes."

"And you'll let him."

Émile turned the watch over in his palm. The brass was warm. Somewhere inside, Jules's last truth waited to be told.

"I'll do what I do," he said, and pocketed the watch.

They went west, into the rain, into the city that wanted them dead on every street corner, and the plate went with them, hidden in a dead man's timepiece.
