Read Chapter 13: The Gunpowder Accord

The powder magazine stank of saltpeter and damp wool, a smell René had come to associate with the possibility of dying very suddenly. He had been assigned to inventory duty—punishment, he suspected, for the commandant's lingering suspicion—and so he stood in the half-dark among barrels of black powder and crates of musket balls, counting what the garrison would need to hold out another week.

He wiped his brow with the back of his sleeve and lifted the next crate onto the workbench. The stencil on the side read *HERZOG VON BAYERN*. Bavarian issue. Odd, that. Breisach was Imperial, and the Bavarians ran their own supply lines. He pried the lid loose with his knife and found, not powder charges, but papers. Correspondence, by the look of it. Bundles of letters wrapped in oilcloth, destined for some office that would never receive them now that the Swedes had closed the roads.

He almost closed the crate and moved on. But one bundle caught his eye—the seal was French. Not the crude wax of a regimental paymaster, but the deep red, carefully pressed impression of a noble house. He pulled the bundle free and untied the cord.

The handwriting was elegant, cramped. The signature at the bottom: *Richelieu's man, if I ever saw one.* René had carried enough clandestine correspondence in his life to recognize the register of a diplomatic communiqué. He scanned the opening lines, and his blood went cold.

*Your Electoral Highness, the arrangement proposed by His Most Christian Majesty remains unchanged. In exchange for Bavarian support in the Rhineland, we shall ensure the Imperial crown's attention remains fixed upon the Baltic. The war must not be permitted to end before the Spanish are bled white and the Emperor's power is broken. To this end, we renew our pledge of 40,000 livres quarterly, to be delivered by our agent in Brussels...*

He read it twice. The date was four months old. The language was nearly identical to the letter he had carried from Paris—the letter that was now ash and scraps in his courier case, destroyed by a Swedish cannonball.

René sat down heavily on a powder barrel. The wood creaked. He caught his breath, then laughed, a short bitter sound that echoed off the stone walls.

He had nearly died a dozen times. He had watched a shepherd's kindness almost get him hanged. He had hidden in a tanner's vat, swum a river, lied to a beekeeper's widow, and carried a message through a warzone—for what? For a document that was, apparently, one of many. A template. A form letter sent to every Catholic prince who could be bought.

He pulled another bundle from the crate. Another letter, different hand, same shape. *The Elector of Mainz assures His Grace that the Swedish alliance is but a temporary convenience...* Another: *Bishop of Würzburg, on the matter of the Mendicant subsidy...*

The French were not prolonging the war through a single secret pact. They were flooding the Empire with money and promises, striking deals with every faction that would take their gold. His letter had been important enough to kill for, but it was not unique. He was a courier carrying one copy of a proclamation that existed in a dozen copies, scattered across a continent already drowning in ink and intrigue.

He should have felt relief. Instead, he felt the weight of the widow's crucifix pressing against his chest beneath his shirt.

Josef Mayr. A pressed soldier from a Tyrolean village, dead or alive somewhere in this siege. The widow had given him shelter, given him a name to seek, and René had promised to investigate. A promise made partly to escape her hut, partly out of guilt, and partly because she had looked at him with the tired eyes of someone who had lost everything and expected nothing.

What would she think if she knew the war that took her son was being prolonged by clerks in Paris who would never see a battlefield? What would she think of the man who had carried one of their letters?

René stood and began going through the crate more carefully. He was looking for something now, though he wasn't sure what. Names, perhaps. Locations. Anything that might tell him where the Bavarian copy had come from, or where it was meant to go.

The third bundle contained a list. Marching orders, by the look of it, for a Bavarian regiment attached to the Imperial forces outside Breisach. Names of officers. Unit designations. And, at the bottom, a note in a different hand: *Detach Mayr's company to the northern breach, where von Werth's cavalry can support the counterattack.*

Mayr. It was a common name in the Tyrol. But René's hand paused over the paper, and he felt the crucifix grow heavier against his chest.

He slipped the list into his doublet, then gathered the letters he had read and returned them to the crate. He was about to replace the lid when something caught his eye at the bottom of the crate—a folded square of paper, sealed with the same red wax as the first French letter. He picked it up and broke the seal.

The handwriting was the same clerk's hand as his own letter. The one he had carried from Paris. The one that had been turning to pulp in the rubble of the walls. He read the opening line, and his heart stopped.

*The terms of the Gunpowder Accord, as amended by His Eminence's agent, are as follows: the war shall continue until the Spanish Netherlands are rendered defenseless and the Emperor's armies are exhausted. In exchange, the Crown of France shall provide...*

Gunpowder Accord. He had not known the letter had a name. He read further, his eyes moving quickly over the familiar phrases, the clauses he had memorized during his ride across the Alps. But this copy was not identical. It contained a second page, a list of names—agents, intermediaries, dead drops—that his own letter had lacked.

He read the list once, then again. Halfway down, a name jumped out at him: *Katarina Vogler, inn at Sankt Jodok, safehouse for Imperial despatches.*

René let the paper fall to the workbench.

The girl who had hidden him from the patrol. The girl who had read through his lies and let him stay anyway. She was not playing a deeper game. She was playing the same game he was. She was an agent—French, or Bavarian, or perhaps simply a woman who sold information to whoever paid—and she had let him walk out of her inn knowing who he was.

He remembered her eyes as he had left, the way she had watched him from the doorway. She had not been warning him about Brandt. She had been cataloguing him. Recording his face, his voice, his lies, for someone else's ledger.

The shattered fragments of his letter were useless. But this copy—this complete copy, with its list of agents and contacts—was worth more than gold. It was worth more than his life.

And it had just fallen into his hands in a powder magazine in a besieged city, as if the universe had decided to test him.

Footsteps in the corridor. René stuffed the letter into his doublet, beside the crucifix and the marching orders, and bent over the crate as the door swung open.

"Delacroix." The commandant's voice was flat, unimpressed. "You are wanted on the wall. The Swedes are preparing another assault, and every man with a working arm is needed."

René nodded, not trusting his voice. The commandant's eyes flicked to the open crate, then to René's face, and lingered there a moment too long.

"You have found something of interest?"

"Just powder charges," René said. "Bavarian issue. The Count of Werth's men must have left them behind."

The commandant said nothing. He held out his hand.

René hesitated. Then he reached into his doublet and pulled out the rolled parchment of the marching orders—not the letter, not the list—and placed it in the commandant's palm.

"Quartermaster's inventory," René said. "I was checking the seals."

The commandant unrolled it, scanned the contents, and then looked at René with an expression that was difficult to read. "You are fortunate, Captain Frick, that I have no time to question you properly. The Swedes do not wait for bureaucratic niceties."

He tucked the parchment into his own coat and gestured toward the door. "To the wall. If you survive, we will continue this conversation."

René followed him out of the magazine, the letter burning against his chest. He had a copy of the Gunpowder Accord. He had a list of French agents operating in the Alps. He had marching orders for a Bavarian unit containing a man named Mayr.

And he had no idea which of these things he would use, or how, or whether he would live long enough to use any of them at all.

The Swedish bombardment began again as he stepped into the daylight, and the ground shook beneath his feet.
