Read Chapter 1: The Dead Drop in Vienna

The Franz Josef Bahnhof smelled of wet wool, coal smoke, and desperation. Vienna in the winter of 1919 was a city of amputees and aristocrats selling silverware for bread, and every face in the crowd seemed to carry the same hollow look Marchand had seen from the Ardennes to the Marne. He stood by the third-class ticket window, a rucksack at his feet that held everything he owned, and watched the hands of the great station clock crawl toward eleven.

The Orient Express wasn't due for another two hours. His berth to Paris had cost him three weeks of courier pay and a favor he'd rather not remember, and he was already beginning to resent every minute of delay.

"Marchand. Jean-Luc Marchand."

The voice came from his left, low and precise, with the clipped accent of a man who had learned French in a classroom rather than a barracks. Marchand did not turn immediately. He let his eyes drift across the reflection in the ticket window, picking out the shape behind him: a thin man in a middle-class coat, wearing a bowler too new for his face.

"I think you've mistaken me for someone else," Marchand said.

"I don't mistake anything, Sergeant." The man stepped closer, close enough that Marchand caught the scent of cheap cologne over the station's grime. "Not your face, not your record, and certainly not the debt you owe certain parties from the spring of 1917."

Marchand went very still. The spring of 1917 meant the Chemin des Dames, meant the mud that swallowed men whole, meant the mutinies that followed the failed offensive. For most soldiers, that was where the story ended—court-martial, prison, or the firing wall. Marchand had been luckier. Or perhaps unluckier, depending on how one counted such things.

He turned, slowly, and faced the man. "I don't know anyone who's owed anything from that spring. The war is over."

"The war is over for the dead, Marchand. For the living, it merely changes its address." The man removed his bowler, revealing a pale scalp and eyes that seemed too close together. "My employer has a task. It requires a man of your particular talents. A man who has been to Russia and come back alive."

"I was never in Russia."

"No." The man smiled, a thin and bloodless affair. "But you were in the Carpathians in the winter of 1916, attached to a liaison mission that was never officially recorded. Don't bother denying it—your file is remarkably complete for a soldier who was supposed to have died in a field hospital."

Marchand's jaw tightened. He'd spent three years and four false identities burying that particular truth.

"What do you want?"

"Just to give you something." From his coat, the man produced a small photograph, creased and worn at the edges, showing a middle-aged man with a high forehead, a beard trimmed close to his jaw, and eyes that held the particular wariness of someone who had spent too much time looking over his shoulder. "His name is Pavel Orlov. Prince Pavel Orlov. He will be arriving at platform nine on the next train from the eastern line. He carries a small leather satchel."

"I'm a courier, not a kidnapper."

"You're an escort. A protector." The man tucked the photograph back into his coat before Marchand could take it—a photograph that Marchand had to memorize in the half-second it had been shown. "You will meet him. You will travel with him to Paris. And you will keep him alive."

Marchand laughed, short and bitter. "Mister, I spent four years keeping men alive, and most of them still died. I'm done with that work."

"Then you're done with being alive as a free man."

The threat hung in the air, as tangible as the breath fog between them.

"The spring of 1917," the man continued, his voice dropping to almost a whisper. "The 43rd Infantry Regiment. A certain corporal was due to be executed for inciting mutiny. A sergeant—a man much like yourself—testified that the corporal had been struck by a shell fragment and was not responsible for his actions. The sergeant vouched for him. The corporal was spared."

Marchand said nothing. He remembered the corporal. A boy of nineteen, standing in the mud of a shell crater, screaming that the generals were murderers and that the war would continue until the soldiers refused to march. Marchand had lied through his teeth to save that boy, citing a battlefield wound that had never happened.

"The corporal's family," the man said, "has long memories."

"I never met his family."

"You met his father. In the Carpathians. The 'liaison mission' that was never recorded—you were the liaison. You reported directly to the father." The man's thin smile widened. "His name was not Marchand, of course. Neither was yours, in that winter. But the father recognized your face in a photograph from the front. He told my employer, who told me. And now we're here."

Marchand felt the station press in around him. The noise, the crowds, the constant flow of refugees and deserters and broken men—all of it seemed to recede into a distant buzz.

"That father," he said slowly, "would be a dead man by now. The war was hard on everyone."

"The father survived. He emigrated to America. He is, I understand, doing very well for himself." The bowler man's eyes glittered. "But you came back here asking for one favor. The mother of the corporal asked through her husband that you be found and helped. That was how you got your papers. That was how you got your courier work with the Red Cross. They opened every door you've walked through since the war."

Marchand's hands, scarred and calloused, tightened at his sides. He had known the work came from somewhere. He just hadn't known who was behind it.

"A man like you," the bowler said, "is not in a position to refuse. The father has asked for nothing since your discharge. He has paid for your quiet, your safety, your new life. Now he asks for one thing in return."

"The father asked for this?"

"Through intermediaries. It is not safe for him to be seen in Europe." The bowler sniffed. "Not with everything that is happening in Russia."

Marchand stared at the clock. Eleven-forty. The eastern train would arrive within the hour.

"Why would the father want to protect a Russian prince?" he asked.

The bowler's thin smile faded. For the first time, he looked almost human—almost worried.

"Because Prince Orlov does not have much time," the man said. "And neither, I suspect, do the rest of us. But that is not something I am paid to know." He pressed a card into Marchand's hand—cream-colored, expensive, bearing only a handwritten name and an address in the Innere Stadt. "His name is Pavel Orlov. Platform nine. If you are late, you will find the job is gone, and so is everything the father has done for you. I suggest you move."

The man turned and walked into the crowd without looking back, swallowed almost instantly by the flow of bodies.

Marchand stood where he was for a long moment, the card sandwiched between his fingers, the train to Paris growing closer by the minute. He could walk away. He had walked away from worse things—from orders, from colleagues, from the memory of mud and blood and boys drowned in shell holes.

But the debt was not to the bowler, or even to the father in America. It was to the boy in the crater, the one who had screamed at the generals while the shells fell. Marchand had lied to save him. He had stood in front of a court-martial board and sworn that the boy's fever had broken his mind, that he deserved mercy, not a bullet. And the boy's family had repaid that lie with papers, money, a new name, a way out of the ruins.

Now they were asking for a return.

The station clock showed eleven-forty-five.

Marchand hoisted his rucksack off the ground, swung it onto his shoulder, and moved through the crowd toward platform nine, his stride long and even, his eyes scanning faces and hands and the curve of coats beneath which weapons might hide.

He did not know what he would find when the eastern train pulled in. He did not know who Pavel Orlov was, or why a Russian prince would need a disgraced French veteran to keep him alive through a continent still patched together with peace treaties and bandages.

But he knew debt. He knew the weight of a life saved and a promise kept.

And as he reached the end of the platform, the great iron clock above him ticking toward noon, he pushed his hand into his coat, found the worn handle of the pistol he carried on every job, and waited for the train.

Behind him, somewhere in the station's growing crowd, he caught the flicker of a uniform—Austrian, by the cut of it—and the way a man in civilian clothes touched the brim of his hat, a signal Marchand had seen a thousand times before.

Someone else knew about the prince.

And they had not come to welcome him.
