“So?”

“The mark of the assassin predates…” Ruzsky stopped.

“What?”

“Hold on a second.” Ruzsky shut the folder on his lap, stood, and replaced it. He moved down the line of shelves, examining the dates. “I’m going to start earlier.”

Pavel didn’t answer. Ruzsky continued until he found the section for 1905. He was recalling not Ella’s history, but Maria’s.

Ruzsky took down the file for the first week of that year. It contained a seamless record of similar, mostly anonymous crimes, from across the Empire. They merged into each other, but he flicked through the pages methodically, before replacing the file and taking the next.

The telegraph traffic for the year was exhaustive, as the revolution which began in St. Petersburg slowly consumed the whole of Russia. It was particularly heavy from Odessa during the summer, as revolutionary fervor spread to the Black Sea Fleet, sparking a mutiny in the battleship Potemkin. Members of the local police department had recorded the string of ordinary crimes that occurred during the period of anarchy, even as the entire fabric of their world teetered on the brink of extinction. Ruzsky gave a wry smile.

He looked up at his partner, who sat with his head bent, absorbed in his task.

He returned to his own file and began to leaf through the pages once more.

“What are we looking for, Sandro?”

“You know what we’re looking for.”

Pavel had not raised his head. “If you say so.”

They worked without a break. Stanislav appeared as the light began to fade.

Ruzsky looked at him, but remained silent.

“I’m surprised you are here,” Stanislav said. “I heard-” The look on Ruzsky’s face persuaded him not to continue. “I’m sorry, anyhow.”

The journalist shrugged. He glanced at Pavel and began fiddling nervously with his mustache. “There’s an alert for Friday and the weekend.”

“What do you mean?”

“The entire Petrograd garrison. I heard Shulgin and Count Fredericks want the reserve battalions brought in from Peterhof and Gatchina, but the Tsar won’t hear of it.”

“I thought the Tsar was at the front.”

Stanislav shook his head. “Apparently not. There are delegations on their way. Italians, French…”

“Why is there an alert?” Ruzsky asked, though he thought he knew the answer.

“I don’t know, but the city is being divided up by military district and they are to patrol the streets before dawn. The Finland Regiment on Vasilevsky, the Preobrazhenskys on South Quay and along Horseguards, the Volynsky from the Nevsky down to Nicholas Station…”

Ruzsky put his folder down and stood.

“What are you doing down here?” Stanislav asked, looking about him.

“Why is there an alert?” Ruzsky asked again.

Stanislav shrugged.

“You must have heard speculation.”

Stanislav said, “I heard you found another body.”

Ruzsky did not respond.

“The newspapers are going to love that.”

“Well, you’d better ask Vasilyev before you get them to print it.”

Stanislav tugged harder at the ends of his mustache. “What are you doing down here?” He glanced at Pavel, who still had not moved.

“Some research,” Ruzsky answered.

“Into what?”

“Never mind.”

“It is still your case?”

Ruzsky took a pace forward. “I’d like you to do something. I want to know what all the murder victims were doing back in Petersburg, especially the American. He was staying at the Astoria, so go down there; talk to the bellboys and the chambermaids. See what you can find out. What did the American do with his time here? What visitors did he receive? Where did he go when he went out? Did the girl, Ella, ever come there?”

“The Astoria?”

“Yes.”

“He was staying at the Astoria?”

“Yes.”

Stanislav raised an eyebrow. “What else?”

“Just find that out, and get back to me. I want to know exactly what the American’s movements were from the moment he arrived until the moment someone stuck a knife in his chest, out on the ice.”

A few minutes later, Ruzsky tramped up the stairs to the deserted offices of the Criminal Investigation Division. The secretaries had tidied their desks, and all the doors around the central room were shut.

He picked up the telephone on his desk and asked the operator to put him through once again to Colonel Shulgin at Tsarskoe Selo.

It took a long time to make the connection and when it was achieved, a woman answered, her voice distant. “Yes?” she demanded.

“Might I speak to Colonel Shulgin?”

“Who is it that wishes him?”

“Chief Investigator Ruzsky, Petrograd City Police Criminal Investigation Division.”

“Oh, yes.”

He heard her footsteps receding.

Ruzsky drummed his fingers as he waited.

“Yes?” another voice answered. “Shulgin here.”

“It’s Ruzsky, sir.”

“Oh… yes, Ruzsky.” There was a long pause. “I was sorry to hear about your father.”

“I called you last night, sir.”

“Yes, you said it was urgent. My apologies.”

Ruzsky could tell someone else was listening, or standing close. He hesitated again.

“I’d be grateful if I could speak to you in person at the earliest opportunity.”

“Yes.” Shulgin’s tone was noncommittal.

“Preferably tonight.”

“That is not going to be possible, Chief Investigator.”

“My father’s death was no accident, sir.”

Shulgin was silent.

“It occurred within minutes of an unscheduled meeting with Mr. Vasilyev. I’m sure you will agree that it was quite out of character.”

“The meeting was not unscheduled. And Mr. Vasilyev is privy, I’m afraid, to a great deal of information that disturbs the minds of the sanest of men.”

“That is hard to accept,” Ruzsky said quietly.

“So are many things, at this time.”

“You were close to my father.”

“We were colleagues.”

“Close colleagues.”

“I was aware of your father’s concerns.”

“Would you share them with me?”

Shulgin sighed. “No, Sandro. I’m sorry. I cannot.”

“Am I not to be permitted to know why my father took his own life?”

There was a longer pause. “Nicholas Nikolaevich was a senior government official. Our hands are thus bound in ways we might not wish.”

“So he placed a revolver in his mouth and pulled the trigger purely as a result of the situation in which Russia finds herself at this time?”

Shulgin did not answer, but his silence suggested he also did not believe this was an adequate explanation.

“In the meeting we attended, you made reference to events you expected to take place on Friday or Saturday. You spoke with Mr. Vasilyev about intelligence you had received.”

“Yes.”

“We have been informed that the Petrograd garrison has received specific orders relating to this weekend.”

“Yes.”

“Would you mind telling me why?”

“You know the answer perfectly well.”

“You fear unrest?”

“Yes.”

“It is more than a routine matter?”

“We would not issue an alert without specific intelligence. But what bearing does this have on your investigation?”

“I thought it might shed light on the victims. It is possible that they have been murdered as a result of activities they planned to conduct in the capital.”

Shulgin was silent again.

“There has been another body, sir. A fourth victim. A woman.”

“I see.”

He could tell Shulgin already knew. Ruzsky pictured the colonel standing alone in the hallway of the Alexander Palace, the Tsar and his wife secluded in the rooms behind him, their children asleep. It seemed not just incongruous, but suddenly quite mad that the government of an empire should rest upon such foundations.

“I appreciate the burdens of office,” Ruzsky said. “Especially at this time. But it is not just blind faith that prevents me believing in my father’s suicide.”
