The voices were suddenly louder again. Two men stood in the doorway. They began to walk, their voices booming confidently across the factory floor. One of them whispered something and the other laughed.

Ruzsky edged forward, skirting one of the machines, and looked up. One of the men was Ivan Prokopiev, his closely cropped bullet head instantly recognizable, and the other was Michael Borodin.

Ruzsky stepped back, colliding with Pavel, who began to gesticulate, mouthing that they should leave immediately. Ruzsky shrugged. “How?” he mouthed back. Some of Prokopiev’s men were still in the foreman’s office at the end and Prokopiev and Borodin were now behind them.

Their answer presented itself when the two men returned, still in animated conversation. Ruzsky heard Prokopiev say, “Hurry up,” to his officers at the far end of the walkway, and he and Pavel took this as their cue.

They moved silently up the stairs and then retraced their steps down to the courtyard. They kept moving and did not stop until they had reached the high iron fence surrounding the barracks of the Lithuanian Regiment.

“There is your answer,” Pavel said, trying to recover his breath.

Ruzsky did not respond. His heart was pounding and his palms and forehead were clammy.

“It’s as you suspected. Borodin and Vasilyev are allies. They must have been since Yalta. That’s what lies behind our murders. Vasilyev must be eliminating everyone who is aware of that association.”

“It’s a neat theory,” Ruzsky conceded.

“Don’t tell me you’re surprised?”

“Whatever one might think of Vasilyev-or his associate-I can’t picture either of them following in someone’s footsteps like a misguided amateur and then slashing him seventeen times for the fun of it.”

“Perhaps the other one does the killing. Borodin…”

Ruzsky hesitated. The way in which the boy had been bludgeoned to death made some sense of this, but he still couldn’t accept it. “No,” he said. “I think Borodin and his allies are angered by these killings. If anything, they have disrupted their plans.”

They glanced back down the street to check that they had not been followed. “What are their plans?” Pavel asked.

Ruzsky did not answer. He turned his back so that he was shielded from the wind.

“At that meeting,” Pavel went on, “Vasilyev was giving Shulgin and your father the impression that these men were dangerous. Why was he doing that?”

“I don’t know.” Ruzsky looked at his colleague. He needed time to think. “Go home and get some sleep. We’ll talk later.”

“Will you be all right?”

“Of course.”

“Don’t do anything foolish. Remember what happened in Yalta.”

Ruzsky shook his head. “I will see you in the office at one.”

“What-”

“We have something we need to do.”

Ruzsky tapped his colleague’s shoulder affectionately and then started walking. After twenty yards, he stopped and turned back to watch Pavel melting into the night.

He and Tonya lived over in Palyustrovo, beyond the Finland Station. It was a walk almost as long as his own, but at least a warm bed awaited him.

Ruzsky turned into the wind and began the journey back to Vasilevsky Island. He didn’t encounter a droshky, so had to keep walking, crossing the Birzhevoy Bridge to the Strelka alongside a peddler pushing his cart laboriously up the incline. Ruzsky helped the man for twenty yards or so-until the downhill section of the bridge-earning himself a toothless grin.

He pulled his cap down farther and narrowed his eyes against the wind as he slipped through the austere buildings that dominated this end of Vasilevsky Island. He thought of the summer days when he and Dmitri had stood with the servants close to where University and Nicholas Quays merged, listening to the whistling of the winches and the shouts of crewmen from all over the world.

The memory of such innocent pleasures troubled him. Would that world ever return? He was worried not for himself, but for Michael.

He would see his boy tomorrow, come what may.

Ruzsky was so lost in thought that he almost walked straight into them. Only the presence of a dark automobile in the region of Line Fourteen-an unusual sight-alerted him.

He stopped and ducked into the shadows. There were two officers in the car. They were Prokopiev’s men, not the surveillance teams, who would have been much less conspicuous.

Ruzsky edged back into the shadows and moved silently away. Ironically, he knew there was now only one place in the city he would be safe.

At night, the servants locked and bolted the entrance to the yard at Millionnaya Street, but there was a gap above the doors that Ruzsky had slipped through many times as an adolescent.

Inside, he climbed the stone steps to the kitchen door and glanced in. A light was on. He knew that Katya awoke early. He checked his watch. It was half past five in the morning.

Ruzsky waited. Even out of the wind, it was still bitterly cold.

Katya bustled into the kitchen and he watched her for a few moments before knocking gently on the window. She looked around, startled, then frowned as she examined him more closely. Ruzsky realized that she had not initially recognized him.

She came to the back door, opening it a fraction, as if not wanting him to take his entry for granted. “Master Sandro,” she said, her face flushed.

“Katya.”

She did not move.

“Might I come in?”

“They’re all asleep, Master Sandro.”

“I want to see my boy, before they wake.”

Reluctantly, and only because she felt she had no choice, Katya eased the door back and allowed him entry. In the hallway within, she examined him cautiously. Ruzsky realized, through her reaction, what a mess he must look. He hadn’t seen himself in a mirror for days and he doubted it would be a pretty sight. “Thank you,” he said quietly.

“Be careful, Master Sandro,” she said.

Ruzsky smiled. He turned and walked up the stairs, drifting silently through the house.

He climbed the last steps to the attic.

In the darkness, Ruzsky walked forward until he stood over his son.

Michael lay on his front, his head to the side, clutching his worn-out bear. He was breathing easily. A new train track had been assembled upon the floor, reaching right to the edge of the bed.

Ruzsky studied him.

He reached down and touched his son’s soft head, then leaned down and kissed his ear. “I love you, my boy.”

Fatigue finally began to overwhelm him and, as he straightened, he felt unsteady on his feet. He turned and, trying not to wake Michael, slipped back across the hallway.

By the light of the moon, he saw Ilusha’s abandoned animals on the shelf above his bunk and found himself moving toward them. He looked at the photograph of his brother, with the two candles on either side of it.

Ruzsky stopped. The bed was already occupied.

Dmitri sat up, his hair tousled and his face full of sleep. “Sandro? What are you doing here?”

Ruzsky did not answer. He listened to the sound of his own breathing.

Dmitri lay down again, with his back to the door. He was in the full dress uniform of a colonel of the Guards. “There is room,” he said, shuffling to the side of the bunk.

Ruzsky waited for a few seconds, then walked forward. He lay down beside his brother.

The house was silent.

He looked up at the tattered toy elephant on the shelf above and the painted wooden soldier at the end of the bed. He closed his eyes.

Dmitri reached out for his hand and held it. Ruzsky gripped it tightly.

They lay still, just as they had done in the days and weeks after Ilusha’s death.

Ruzsky turned over and wrapped his arm around his brother’s chest.

He relaxed his grip, but did not move. After a few moments, sleep overwhelmed him.
