Read Chapter 29: The Debt Called Due

The airship shed stank of coal smoke and damp rope. Rothschild's gold waited in three iron-bound crates, each coin gleaming dully under the lantern light. Étienne ran his palm across the nearest stack, feeling the cold weight of betrayal.

“A fortune to buy a riot,” he said.

Rothschild shrugged from the doorway, his fur-collared coat absurd in the filth of the hangar. “A riot buys time. Time buys my ships safe passage to London. You get your family out of Prussia. Everyone wins.”

Étienne said nothing. Behind him, Marchand was already moving, his quiet hands unfolding canvas and checking seams. The artisan had not spoken since they'd left the cellar, but his eyes tracked every corner of the shed, every shadow where a spy might crouch.

“Load it,” Étienne said.

The gold took twenty minutes to haul into the wicker basket. It sat heavy, dragging the envelope low against its tethers. Étienne climbed in and tested the valve lines, the rudder cables, the lift. A cold wind off the Seine rattled the shed door, and beyond it, the distant crump of Prussian shells rolled like thunder at the edge of the world.

Marchand climbed in after him, silent, carrying a canvas satchel that clinked with something that was not gold.

“You're not coming,” Étienne said.

“I am.”

“The basket's rated for two, not three. The gold's already pushing weight.”

Marchand's jaw set. “Then the gold can go over the side first.”

They stared at each other until Étienne looked away. “Fine. But if we go down, we go down together.”

He turned to the crate of black powder he'd had Marchand smuggle in from the ruined powder mill on the Rue de Sèvres. Fine-grained and volatile, it filled two canvas sacks. Étienne packed them beneath the gold, laid a train of fuse cord through a gap in the wicker, and fixed the cord's end to a slow-burning match he could strike with a pull-cord from the basket.

“When the coins hit,” he said, low, for Marchand's ears only, “they'll be sitting on enough powder to wake the dead.”

Marchand's eyes flicked to the fuse, then back to Étienne. “You're not planning a riot.”

“I'm planning a funeral.”

The shed doors opened. The ground crew—hired men, Rothschild's paid hands, not French soldiers—hauled the ropes and let the envelope rise. Étienne worked the ballast, dumping sand in careful handfuls until the basket lifted clean off the floor and swayed into the grey Paris sky.

Below, the city lay wounded. Fires still smoldered in the southern districts from the morning's bombardment. The Tuileries stood gutted. The Seine ran grey and cold between the bridges, and everywhere the thin smoke of cookfires rose from the hungry streets.

Étienne banked the balloon northeast, toward the Prussian lines. The gold settled against the floor of the basket with a soft, murderous weight. Marchand crouched in the corner, his satchel clutched to his chest, watching the ground unwind beneath them.

“You knew,” Étienne said, not looking at him. “About the powder. You knew I wasn't going to scatter the coins.”

“I guessed.”

“And you came anyway.”

Marchand was quiet for a long moment. Then: “The commandant has a telegraph line from his headquarters to the front. I saw the wire runs. If the depot explodes, the signal goes dead. He won't know the retreat is coming until it reaches him.”

Étienne looked at him sharply. “Retreat?”

“You said funeral. A burning depot behind their lines, in the middle of an occupied advance—they'll pull back. No army holds ground with its ammunition exploding behind it.” Marchand's voice was flat, certain. “The Prussians will retreat past the racecourse, past the outworks where Kohl's camp is pinned. And when they do, they'll find their own supply lines broken and a Paris that fights on.”

“You're not here for me,” Étienne said slowly.

“I'm here for France.”

The wind pushed them east. Étienne watched the Prussians camps spread beneath them like a steel stain—tents, trenches, artillery parks, wagon trains. In the distance he could see Kohl's field headquarters, the commandant's pennant snapping over the hut where his brother had been held. Where his brother was still held, unless—

He forced the thought away. The mission came first.

“Here,” Marchand said, pointing. A dark square of earthworks below them, crates stacked in neat rows, wagons drawn up in a line. The ammunition depot. Guarded, of course. A handful of men moved between the tents, small as ants.

Étienne pulled the valve cord and dumped ballast. The balloon sank fast, the wind carrying them toward the depot. He could hear the guards shouting now, could see them pointing. A shot rang out, then another. The bullets whipped past the basket.

“Hold steady,” Marchand said. He drew a pistol from his satchel—the bomb still in there, untouched under the canvas—and returned fire. A guard crumpled. The rest took cover.

Étienne reached for the pull-cord that would release the bottom of the basket and dump the gold. But he did not pull it yet.

He leaned over the edge instead, watching the depot grow closer, watching the crates and wagons and powder boxes take shape. Rows and rows of shells, of cartridges, of the instruments of siege.

Not all the gold needed to fall.

Étienne hauled one of the canvas sacks from beneath the coins and cut it open. Black powder spilled across the basket floor. He grabbed the slow-match, lit it with a sulfur-tipped striker, and shoved the burning cord deep into the powder.

“What are you doing?” Marchand's voice cracked.

“Making sure it catches.”

He heaved the sack over the side. The powder scattered in a black cloud, drifting down toward the depot roofs, toward the crates. The wind caught it, spread it thin—but some of it settled.

The match cord still burned in his hand. Étienne pulled the release cord for the gold. The bottom of the basket swung open, and the coins poured out in a glittering cascade. For one terrible moment they hung in the air, shining, beautiful—a fortune falling from the sky.

Then they hit the roofs, hit the crates, hit the ground. And the powder Étienne had scattered caught the spark from the first bag—

The world turned white.

The shockwave hit the balloon like a fist, snapping the envelope upward. Étienne was thrown against the wicker, his ears ringing, his vision a fog of fire. Marchand screamed something he couldn't hear. The basket spun, hung, fell.

Below them, the depot was a roaring column of flame spread across the earthworks. Secondary explosions cracked and boomed—shells cooking off, powder stores igniting, the fire leaping from wagon to wagon. Guards were running, scrambling away from the inferno, their officers shouting orders that no one could hear.

And beyond the depot, the Prussian lines were moving. Men pulling back from their trenches, limbers being hitched, wagons fleeing the wall of fire that marched across their camp. The retreat had begun.

Étienne clutched the basket's rim and watched the fire spread, watched the Prussians run, watched the great engine of the siege begin to break apart. He had done more than scatter gold. He had burned their war.

Marchand was staring at him, face pale. His satchel hung open, the bomb visible inside—a black sphere of iron and fuse, still cold.

“You meant to destroy it all,” Marchand said.

“I meant to give Paris a chance.”

Below, the fire roared. The retreat became a rout. And somewhere in that chaos, Étienne's brother was still hostage in a camp that was about to be overrun.
