Pavel tried to take responsibility, but Ruzsky had overruled him. It had been his own idea, he told the secret police chief, Igor Vasilyev, and his thugs.

Ruzsky’s punishment had been effective banishment to Siberia as the chief investigator of the Tobolsk Police Department.

Ruzsky tried to return his friend’s smile. They both knew that Pavel’s punishment would have been much worse. Ruzsky might have been the black sheep of his distinguished, aristocratic family, but the Ruzsky name itself and the fact that his father was a government minister still carried weight. It had limited the scale of punishment-back then, at least.

Ruzsky finally heard a bolt being pulled back and the palace door swung open. Three men in the distinctive uniforms of the Yellow Cuirassiers emerged from the darkness. The elder of the men-a sergeant-had white hair and a mustache like Pavel’s. His two young companions were nervous and held their rifles firmly in both hands. In the grand hallway behind them, Ruzsky could just make out the tip of a chandelier.

“City police,” Ruzsky said. He wasn’t in the mood to offer felicitations for the dawning of a new year.

“You should have come to the other side.”

“There have been two murders, out here, on the ice.”

The sergeant walked forward, followed by his companions. They stood in a small group looking out toward the torches in the middle of the frozen river. “Yesterday it was a drunk,” he said, pointing at the deserted road in front of him. “Froze to death just here.”

“I fear this is a little different. The victims were stabbed-”

“A week ago, someone was stabbed out in front of the Admiralty.”

“A domestic dispute,” Pavel corrected him. “Two brothers. Both still alive.”

“Have you been on duty all night?” Ruzsky asked.

“Of course.”

“You’re on detachment?”

The Yellow Cuirassiers-officially His Majesty’s Life Guard Cuirassier Regiment-were based out at Tsarskoe Selo, in the small town that surrounded the royal palaces there. It was about an hour’s train ride from the capital.

The sergeant did not answer.

“There are other guards?” Ruzsky went on.

The man shrugged. “On Palace Square. They don’t move unless we call for them.”

Ruzsky looked down the embankment toward the Hermitage. “There is no one out here?”

“A sentry either end until midnight. After that, it is not necessary. The shutters on the ground and first floors are closed. We would hear any commotion.” He was defensive.

“There are no patrols?”

His cheeks flushed slightly. Ruzsky didn’t wish to press the point; it had been New Year’s Eve, after all. “What time did you and your men come on duty?”

“If you wish to ask questions, you will have to apply to the head of the guard detachment or the office of the palace police.”

“Come on,” Pavel said softly, before Ruzsky could get annoyed. “A couple of lovers have been sliced up out there. We just want to check to make sure no one saw anything, then be on our way.”

The man’s face softened. He breathed out. “Cigarette?” Pavel asked, taking out a tiny tin case from the pocket of his coat and offering it around the group.

The men hesitated-smoking on duty was strictly forbidden-before each taking one in turn. They lit up and smoked in silence, suddenly conspiratorial.

The sergeant looked out at the constables still guarding the bodies on the ice. It was marginally less cold here, in the shelter of the giant porch.

“We came on duty at midnight. I did my last rounds about an hour later. I walked along the embankment to check for drunks. Then I locked the door.”

“You stand here, inside the hallway?”

“We check the rooms periodically, but, as I said, all the shutters are locked, except those by the door.”

“You didn’t see or hear anything?”

The sergeant shook his head and so did his young companions. Ruzsky could see they were telling the truth. He suspected they’d probably been playing cards as the New Year dawned.

That, and the fact they had accepted a cigarette while on duty, was, he thought, a sign of the times. He wondered if the men had seen action at the front. The sergeant, certainly. The others looked too young.

“When you came out at one o’clock, you didn’t see anyone at all?”

“There was a group farther down, by the Admiralty. I think they’d just crossed the river, but they were going home. It was quiet after that. If we’d heard anyone else, we’d have moved them on. We don’t allow people to linger.”

“Could anyone have seen something from one of the upstairs windows? A servant?”

He shook his head. “These are all state rooms at the front. There are family bedrooms on the top floor, but none are occupied.” The sergeant gestured toward the group on the ice again. “It’s quite far out.”

“But extremely visible on a clear night.”

“Yes.” He shook his head and looked genuinely apologetic. “You can talk to the head of the household later on. He could tell you whether there might have been anyone in the front rooms, but I’m afraid I cannot help you.”

The sergeant turned and retreated, taking the younger men with him. The door shut with a loud bang and the silence descended once more, save for the iron chain above them creaking in the icy wind. An ambulance had parked on the Strelka and two men were carrying a stretcher out to retrieve the bodies.

“It’s a strange place for a murder,” Pavel said. “At this time.”

Ruzsky didn’t answer. He glanced over his shoulder. They were only a few minutes from his parents’ home here, and he thought of his son Michael sleeping, curled up with his teddy bear pressed to his nose.

“We’d better start looking for the knife,” he said.

Ruzsky returned to the edge of the ice. As he reached the bottom of the steps, he heard the sound of a car door being shut and turned to see two men in fedoras getting out of a large black automobile farther down the embankment.

The men leaned over the wall and surveyed the scene on the ice.

“The Okhrana?” Ruzsky asked quietly.

It was only half a question. They both knew perfectly well that these were Vasilyev’s men. The change in Pavel’s demeanor was palpable.

“What are they doing here?” Ruzsky asked.

Pavel did not answer. He was staring at them, trying to conceal his unease.

The two secret policemen sauntered back to their automobile and got in. The car swung around and returned the way it had come.

Ruzsky and Pavel watched as it disappeared down the embankment before turning left over the bridge in the direction of the St. Peter and St. Paul Fortress.

R uzsky didn’t want to go back onto the ice, so he got Pavel to instruct the constables and then stood on the embankment and watched as they searched across the river. It was a huge area and they moved quickly, reminding him of a pack of hunting dogs eager to pick up a trail. Maybe they just wanted to get home.

The wind had dropped a little, but it was still bitterly cold. The dim light gave the appearance of fog and Ruzsky could now only just make out the spire of the cathedral on the other side of the river. It wasn’t going to make their search any easier.

It was still early, but they were not alone on the ice; two constables from the marine police had begun working the section of the river around the Strelka. As Ruzsky watched, one leaned forward and probed gently with his foot, before reaching back, taking a pole with a red flag from his colleague, and sticking it into the ice.

The pair appeared oblivious to the fact that a murder investigation was going on around them. They were looking for hazards, patches of black water, where a thin covering of ice concealed a pocket of five or six feet of water and a thicker layer of ice underneath.
