Dmitrii’s guards had drawn their swords; Kasyan’s men circled her brother on their fine horses. Blades dazzled in the indifferent sun.

“I’m all right, Sasha,” Vasya called to her brother. “Don’t—”

Kasyan cut her off. “I suspected,” he said in an even voice, directing his words to the Grand Prince. The half-formed brawl on the ice paused. “I only knew for sure today, Dmitrii Ivanovich.” Kasyan’s expression was grave, except for the glint in his eyes. “There is a great lie and a gross immodesty here, if not worse.” He turned to Vasya, even touched her cheek with a burning finger. “But surely it is the fault of her lying brother, who wished to dupe a prince,” he added. “I would not blame the girl, so young is she, and perhaps half-mad.”

Vasya said nothing; she was looking for a way out. Solovey gone, her brother surrounded by armed men…If any of the chyerti were there, she couldn’t see them.

“Morozko,” she whispered, reluctantly, furiously, despairingly. “Please—”

Kasyan cuffed her across the mouth. She tasted blood on a split lip; his expression had turned venomous. “None of that,” he spat.

“Bring her here,” said Dmitrii in a strangled voice.

Before Kasyan could move, Sasha sheathed his sword, slid from his mare’s back, and stepped toward the Grand Prince. A thicket of spears brought him to a halt. Sasha unbuckled his sword-belt, cast the blade into the snow, and showed his empty hands. The spears retreated a little. “Cousin,” Sasha said. At Dmitrii’s look of fury he changed it. “Dmitrii Ivanovich—”

“Did you know of this?” hissed Dmitrii. The prince’s face was naked with the shock of betrayal.

In Dmitrii’s face, for a moment, Vasya saw the plaintive phantom of a child who had loved and trusted her brother wholeheartedly, his illusions now dashed and broken. Vasya drew a breath that was almost a sob. Then the child was gone; there was only the Grand Prince of Moscow: solitary, master of his world.

“I knew,” replied Sasha, still in that calm voice. “I knew. I beg you will not punish my sister for it. She is young, she did not understand what she did.”

“Bring her here,” said Dmitrii again, gray eyes shuttered.

This time, Kasyan hauled her forward.

“Is this truly a woman?” Dmitrii demanded of Kasyan. “I will have no mistake. I cannot believe—”

That we fought bandits together, Vasya finished for him, silently. That we endured the snow, and the dark, and that I drank in your hall and offered you my service. All that Vasilii Petrovich did, for Vasilii Petrovich was not real. It is as though a ghost did it.

And indeed, looking into the bow-marks of strain bracketing Dmitrii’s mouth, it was as though Vasilii Petrovich had died.

“Very well,” said Kasyan.

Vasya did not know what was happening until she felt Kasyan’s hand on the ties of her cloak. And then she understood and threw herself at him, snarling. But Kasyan got a hand on her dagger before she could; he kicked her legs out from under her and pushed her facedown into the snow. A knife-blade—her own knife-blade—slid cold and precise down her back. “Be still, wild-cat,” Kasyan murmured while she thrashed, suppressed laughter in his voice. “I will cut you else.”

Dimly she heard Sasha, “No, Dmitrii Ivanovich, no, that is a true maid, that is my sister Vasilisa, I beg you will not—”

Kasyan pulled the cloth apart. Vasya jerked once at the claws of cold on her skin, and then Kasyan hauled her upright. His free hand ripped away jacket and shirt together, so that she was left half-naked before the eyes of the city.

Tears gathered in her eyes, of shock and shame. She shut them a moment. Stand. Do not faint. Do not cry.

The bitter air scoured her skin.

One of Kasyan’s hands ground the bones of her arm together; the other seized her hair, twisted it, and pulled it away from her face so that she had not even that to hide behind.

A noise rose from the watching crowd: of laughter mingled with righteous indignation.

Kasyan paused a moment, breathing into her ear. She felt his glance flicker over her breasts and throat and shoulders. Then the lord raised his eyes to the Grand Prince.

Vasya stood shaking, afraid for her brother, who had launched himself at the men hemming him in and been brought down by three, held hard in the snow.

The prince and his boyars stared with expressions ranging from bewilderment, horror, and rage to sniggering glee and dawning lust.

“A girl, as I said,” Kasyan continued, his reasonable voice at odds with the violent hands. “But an innocent fool, I think, and under the sway of her brother.” His sorrowful glance took in Sasha, kneeling, appalled, held by guards.

A murmur swept through the crowd, out and back. “Peresvet,” she heard, and “Sorcery. Witchcraft. No true monk.”

Dmitrii’s glance slid from her booted feet to her bared breasts. It stopped at her face and lingered there, without feeling.

“This girl must be punished!” cried one of the young boyars. “She and her brother have brought shame on all of us with their blasphemy. Let her be whipped; let her be burned. We will not suffer witches in our city.”

A howl of approval met his cry, and the blood drained slowly from Vasya’s face.

Another voice replied: not loud, but cracked with age, and decisive. “This is unseemly,” it said. The speaker was fat, his beard a fringe, and his voice calm against the gathering rage. Father Andrei, thought Vasya, putting a name to him. Hegumen of the monastery of the Archangel.

“Punishment need not be debated before all Moscow,” said the hegumen. His eyes flicked to the people seething on the riverbank. The shouts were growing louder, more insistent. “These will riot,” he added pointedly. “And perhaps endanger the innocent.”

Vasya was already cold and sick and frightened, but these words gave her a fresh jolt of terror.

Kasyan’s hand tightened on her arm, and Vasya, looking up, saw his flash of irritation. Did Kasyan want the people to riot?

“As you say,” said Dmitrii. He sounded suddenly weary. “You—girl.” His lip curled on the word. “You will go to a convent until we decide what to do with you.”

Vasya had her lips open on another protest—but it was Kasyan who spoke first. “Perhaps this poor girl would be easier with her sister,” he said. “Truly I think she is an innocent in her brother’s wicked plotting.”

Vasya saw the quick malice in his eyes, directed at Sasha. But it did not enter his voice.

“Very well,” said the Grand Prince flatly. “Convent or tower, it is all one. But I will put my own guards at the gate. And you, Brother Aleksandr, will be confined under guard in the monastery.”

“No!” cried Vasya. “Dmitrii Ivanovich, he did not—”

Kasyan twisted her arm once more, and Sasha met her eyes and shook his head very slightly. He put out his hands to be bound.

Vasya watched, shivering, as her brother was pulled away.

“Put the girl in a sledge,” Dmitrii said.

“Dmitrii Ivanovich,” Vasya called again, ignoring Kasyan’s grip. Her eyes watered with the pain, but she was determined to speak. “You promised me friendship once. I beg you—”
