Ruzsky put the form down, dipped his pen in the inkwell, scrawled, Is this bureaucracy really necessary? and put it back in the envelope and readdressed it.

Next was a thick sheaf of telegraphs responding to Pavel’s All Russias bulletin.

There were only three that showed any promise. The Moscow City Police had made two sightings of an American wanted on suspicion of espionage, theft, and affray who traveled under the name Douglas Robertson.

Kazan reported that a Canadian traveling under the name Robert Jones had failed to pay his hotel bill in August 1914.

The most encouraging was from Yalta. American wanted, it read, in connection with armed robbery, October 1910. Fits description. More details upon request. Detective Godorkin, Yalta 229.

Ruzsky leaned back, rested his feet on the edge of the desk, and stared at the small religious icon hanging on the wall.

He imagined Ella as she might have been while alive. He pictured her as shy and timid; the American, aggressive and manipulative. A pretty royal nanny and a thieving brigand; it was an unlikely romance.

The minute hand on the clock moved with a loud clunk.

Ruzsky headed downstairs. The machines in the communications room were idle. The solitary operator was drinking coffee and reading his newspaper.

Ruzsky handed him the three telegraphs and asked him to get onto Moscow, Kazan, and Yalta for further details.

Back in his office, Ruzsky glanced at the clock again, though he had been acutely aware of the time all evening.

He sat down, pulled open the drawer, and took out the roll of ruble notes that had been removed from the dead man’s pocket. He spread them out in order of the numbers outlined on the left-hand side of each note.

He stared at them, looking for a flaw to the theory he’d shared with Pavel. If you assembled the notes like this, you got the order of the letters. The numbers on the right could refer to a page and line number. But he could get no closer to breaking the code without knowing what had been used as the key.

Ruzsky shifted the paperweight to and fro, deep in thought.

He noticed that a figure had crept into the doorway and was leaning back, watching him. “Only a rat moves that quietly,” he said.

“Only a fool allows himself to be burned twice.”

Stanislav swung in through the door and sauntered over to Pavel’s desk. He perched on the end of it, his short legs not quite reaching the floor. His leather boots were in as advanced state of disrepair as Ruzsky’s own.

“Did you talk to the newspapers?” Ruzsky asked.

“I tipped one or two off.”

Stanislav was sober, but he looked tired, his thin face yellow with ingrained dirt. “Was that you last night?” Ruzsky asked.

Stanislav didn’t answer. He was stroking his stubble and looking at the floor.

“Up to something you’d rather I didn’t know about?”

The journalist still didn’t reply.

“So, what are you trying to tell me?”

Stanislav took out a packet of cigarettes, lit one, and threw the pack over toward Ruzsky, who sent it straight back.

“How did Prokopiev know about the bodies?” Stanislav asked.

“I have no idea. Probably from one of the constables.”

“That’s a coincidence.”

Ruzsky frowned.

“That’s what you said last time,” Stanislav said. “You-or rather Pavel, with your agreement-put that pervert in the cell at the end of the corridor and told his fellow inmates what he’d been up to. When I asked you who told the Okhrana, you said probably one of the constables. But Prokopiev was here within an hour of the man’s death.”

“I still don’t see your point.”

“Almost without exception, we now have a different set of constables. So, one hour after the bodies are brought in from the ice this time, Prokopiev is around to remove them.”

“So?”

“They knew. Someone high up is singing down the wire.”

Ruzsky did not respond.

“In another time, maybe that wouldn’t matter, but you took three years in exile and Vladimir ’s man wound up in the Moyka with a knife in his back. It’s not a game anymore.”

They were silent. The clock ticked loudly on the wall and Ruzsky glanced at it.

“Spell it out,” he said.

Stanislav shrugged. “If I had the answers, I’d tell you.”

“I’ve got to go.”

Ruzsky got up and put on his coat, slipped the ballet ticket into his pocket, and walked briskly along the corridor.

By the time Ruzsky arrived, the intermission had begun. The first-floor lobby was thronged with theatergoers discussing the performance, the hubbub rising toward the curved ceilings as liveried waiters, balancing silver trays, weaved through the throng. The men were dressed in white ties and tails, the women long dresses and gloves, diamonds glittering in the light spilling from the chandeliers.

Here, outside the dress circle, tradition dictated that theatergoers walk slowly around the edge of the room, arm in arm.

Ruzsky hesitated at the top of the stairs, momentarily dazzled by the finery on display. Petersburg and Russia really were two different countries. This city was as sophisticated and European and rich as most of Russia was backward, remote, and poor. The salons of the capital and the endless pine forests of the interior bore no relation to each other, and he belonged wholly to neither world.

He glanced at his ticket and then at the signs directing him up to the top floor.

As Ruzsky turned back up the stairs, his father’s booming laugh stopped him in his tracks. His family had spilled out of their box and into the corridor. The landing was crowded, but not enough for him to credibly pretend he had not seen or heard them. He found himself propelled across the rich red carpet behind the dress circle boxes. They were drinking champagne, clustered around a low wooden table laden with bottles in silver buckets. Ruzsky’s father stood at the center of the group.

Dmitri’s German wife, Ingrid, was at his shoulder. She was coldly beautiful, long blond hair framing a neatly formed, perfectly made-up face. She had a petite nose and a small mouth, her personality so naturally shy and reserved that Ruzsky had rarely been able to penetrate much beneath the surface. But her kiss tonight was warm and her eyes sparkled as he stepped away from her. Was it, he wondered, just the natural empathy of betrayed spouses?

Dmitri stepped down from the box, his face flushed. “Sandro,” he said, glowing with pleasure. Vasilyev was behind him, followed by Irina.

“I believe you know one another,” Ruzsky’s father said stiffly, gesturing toward the chief of the Okhrana.

“Yes,” Ruzsky said, stunned by the man’s sudden presence in the bosom of his family. “Yes,” he said again, “I believe we do.”

Irina was staring at him as Dmitri stepped forward and hugged him so tight his ribs almost cracked. “The prodigal returns,” he said, turning toward the silent company. “Come on,” he said. “This ridiculous feud cannot go on forever.”

Dmitri’s tone was laced with jollity, but it carried an unmistakably serious plea. He stood next to his brother, an arm around his shoulder, the two of them facing the assembled company.

Ruzsky found it impossible to avoid Vasilyev’s hooded gaze.

Irina’s face was flushed red, her eyes barely concealing her anger at his presence. Perhaps the Grand Duke was close by.

“Sandro must join us,” Dmitri exclaimed. “A benchmark performance.” As Ruzsky saw the hurt in Ingrid’s eyes, he realized how drunk his brother was.

They remained silent. Vasilyev continued to stare at him with intense, unblinking eyes. Ruzsky tried to summon enough energy to retreat with grace, but found himself catching his father’s eye. Just for a moment, beneath the severe frown, he thought he saw his expression soften. “Sandro must join us,” he said. “Of course.”
