Read Chapter 6: The Diplomat's Double

The clatter of hooves and boot-heels in the cobbled courtyard yanked Étienne from a shallow, dreamless doze. He’d made a nest of burlap sacks in the corner of the metalworker’s studio, gun oil and cold iron in his nose, Valeux’s shallow breathing a metronome in the dark. Now that breathing hitched. Valeux was awake, hand already creeping toward the revolver on the bench beside him.

Before either man could move, the door shuddered under a heavy fist. “Vautrin! By order of the Governor of Paris—open this door!”

Three knocks. Military. Not Prussians, not yet. Étienne crossed to the door and hauled it open. A French officer stood on the threshold, lamplight spilling across his greatcoat and the brass buttons of the 44th Line Regiment. He was young, maybe twenty-five, with a waxed mustache and eyes that had never missed a meal. Behind him, two soldiers held lanterns. And between them, wrapped in a traveling cloak the color of wet slate, stood a third man.

This man was older, soft-jowled, with the hands of a clerk and the weary patience of a man accustomed to being obeyed. He looked at Étienne the way a passenger looks at a coachman—expectant, slightly annoyed.

“Monsieur Vautrin,” the officer said, stepping inside without invitation. “I am Captain Delacroix. You have been the subject of grave misunderstanding. This man—” he gestured to the cloaked figure, “—is Antoine Valeux. The *real* Antoine Valeux. Envoy of the National Defense Government, carrying sealed terms of conditional surrender, bound for Brussels to negotiate with Prussian intermediaries.”

Étienne’s blood went cold. He turned to look at the man on the cot. The wounded man. The man with the soldier’s hands and the Prussian artillery map folded in his coat.

The impostor’s eyes met his. For one electric second, there was something there—not fear, but calculation. A chess player caught mid-gambit. Then the impostor moved with a speed that belied his wound. He lunged off the cot, shoving Étienne aside, and crashed through the rear window in a shower of glass and splintered wood.

Delacroix shouted. The soldiers piled after him, lanterns swinging, but the yard beyond was a maze of rusting iron and collapsed sheds. By the time they reached the window frame, the impostor had vanished into the wet black mouth of a sewer grate, its iron lid still clattering as it settled.

“He’s gone,” one of the soldiers said, uselessly.

Étienne stood in the center of the ruined studio, heart hammering. The coded artillery map—the map in his brother’s hand—was gone too. The impostor had taken it with him.

Delacroix turned on him, face flushed with fury. “You were about to fly a Prussian agent over our lines. You were about to deliver a spy to Berlin.”

“I didn’t know,” Étienne said. The words tasted like ash. He’d known something was wrong. He’d felt it in the man’s contradictions, in his soldier’s grip on the wine glass, in the way he’d flinched at the sound of Prussian mortars—not with fear, but with recognition. Étienne had read all the signs and flown toward them anyway, because the map had Lucien’s handwriting on it. Because his brother’s ghost had finally come within reach.

The real Valeux stepped forward. His voice was soft, almost kind. “This is a costly mistake, Monsieur Vautrin. But not fatal. We must depart before the city wakes. The Prussians will have men watching the launch site. We go at dawn, as planned.”

“As planned,” Étienne repeated. His mind was a storm. The map had been bait—a lure to draw a French agent into Prussian hands. Valeux—the real Valeux—was that agent. And Étienne was meant to carry him into the jaws of the trap.

“Captain,” Étienne said, turning to Delacroix. “The map the impostor carried. Did you know about it?”

Delacroix’s mustache twitched. “A field map. Purportedly of Prussian artillery emplacements west of the city. Crafted by our own intelligence to lure the spy’s contacts into revealing themselves.” He paused. “It was a decoy. A fiction.”

A fiction written in his brother’s hand. Lucien had faked his death at Sedan, and now he was writing fictional maps for French intelligence—or for Prussian intelligence disguised as French. Étienne’s head swam.

“You flew him here,” Delacroix continued, voice hardening. “You sheltered him. You were prepared to carry him over the lines. Do you understand how this looks?”

“I understand,” Étienne said quietly.

“You were seen at the Rothschild bank. You’ve been registered flying north, unexplained. The military has had its eye on you for weeks, Vautrin. If not for the urgency of this mission, I’d arrest you now.”

The real Valeux laid a hand on Delacroix’s arm. “We need him, Captain. There is no other aeronaut in Paris with the skill to thread this route at dawn. Whatever his sins, he is our ship and our sail.” He fixed Étienne with those tired, patient eyes. “You will fly me to Brussels. You will deliver me and my documents, and in exchange, your past becomes a closed book. The unregistered flights. The passenger you never declared. All of it, erased.”

Etienne thought of the detonator in his balloon’s cargo basket, hidden beneath a layer of mail sacks. He thought of Rothschild’s blackmailing smile. Erased. As if any of this could be erased.

“And the man who escaped?” Étienne asked. “The Prussian spy.”

Delacroix’s jaw tightened. “He knows the sewers. He’ll surface at a safehouse we haven’t found yet. But he’s wounded—grazed by a sniper’s bullet, shot by no one. He won’t get far. We’ll find him.”

Étienne looked at the broken window. The sewer grate lay in the yard beyond, cold and still. Somewhere beneath the city streets, Lucien’s ghost was running. And Étienne was being asked to fly the other way.

“Dawn, then,” he said.

The real Valeux smiled. “Dawn.”
