The terrible strength that had animated Sasha’s limbs suddenly vanished. He leaned against his mare’s smoke-smelling shoulder. Nothing. There was nothing left of her. He could not stop shivering.

Dmitrii pushed the loose hair from his brow, made the sign of the cross. Low he said, “God rest her spirit.” He laid a hand on his cousin’s shoulder. “It is for no man to undertake justice in my city without my leave. You will have vengeance.”

Sasha said nothing. But the Grand Prince was surprised at the look on his cousin’s face. Grief, of course, anger. But also—puzzlement?

“Brother?” said Dmitrii.

“Look,” Sasha whispered. He kicked one log apart, and then another, pointed to the remains of the cage.

“What?” said Dmitrii warily.

“No bones,” said Sasha, and swallowed. “No flesh.”

“Burned away,” said Dmitrii. “The fire was hot.”

Sasha shook his head once. “It didn’t burn long enough.”

“Come,” said Dmitrii, looking worried now. “Cousin, I know you wish her alive, but she did go in. She could not have come out again.”

“No,” said Sasha, drawing a deep breath. “No, that would be impossible.” But still he glanced again at the red and black hellscape of the river, and then abruptly went to his horse. “I am going to my sister.”

Startled silence. Then Dmitrii understood. “Very well,” he said. “Tell the Princess of Serpukhov that I—that I am sorry for her grief, and yours. She—was a brave girl. God be with you.”

Words, only words. Sasha knew that Dmitrii could not wholly regret Vasya’s death; she had been a problem he didn’t know how to solve. Yet—the fire had contained no bones. And Vasya—you could not always predict Vasya. Sasha wheeled his mare and kicked her to full gallop up the hill of the posad and through the gates of Moscow.

Dmitrii turned, scowling, to snap orders and marshal his guards. He was very weary, and now there had been two fires in Moscow, the second, in its own way, as destructive as the first.

SASHA FOUND OLGA’S GATES SMASHED, the dooryard trampled. But Dmitrii had sent all of his own men-at-arms that could be spared. They had established some kind of order, kept the outbuildings from looting. The dooryard was quiet.

Sasha passed Dmitrii’s men with a soft word. A few of the grooms had straggled back after the crowd went down to the river. Sasha roused one in the stable and thrust him the reins of his mare, barely pausing.

The snow of the dooryard was daubed and spattered with blood, and there were the marks of boots and blades on the door to the terem. A fearful serving-woman opened at last to his knocking; he had to persuade her to let him in.

Olga was sitting by the hot brick of the stove in her bedchamber, still awake and still dressed. Her face was drawn and gray in the candlelight; exhausted shadows smeared her milky beauty. Marya was weeping hysterically into her mother’s lap, black hair flung about like water. The two were alone. Sasha paused in the doorway. Olga took in his filthy, blistered, soot-streaked appearance and blanched.
