She sat up, grim-faced, and wiped her mouth. “I’m all right, Father,” she said to Sergei.

The boat ground against a dock. Vasya took hold of the pack-horse’s halter, led him ashore. The rope slid against her sweating hands. People were pushing to get into the city before the gates were shut for the night. It was not difficult to fall a little behind the three monks. Morozko’s cold presence paced invisibly beside her. Waiting.

Would anyone recognize her—the witch they thought they’d burned? There were people in front and behind; people all around. She was afraid. The air smelled of dust and rotten fish, and sickness. Sweat trickled between her breasts.

She kept her head down, trying to look insignificant, trying to control her racing heart. The stink of the city was calling up memories faster than she could push them back: of fire, of terror, of hands tearing at her clothes. She prayed no one would wonder why she wore a thick shirt and jacket in the heat. She had never in her life felt so hideously vulnerable.

The three monks were stopped at the gate. The gate-guards held sachets of dried herbs to mouth and nose as they prodded carts and asked questions of travelers. The river darted points of light into their eyes.

“Say your name and your business, strangers,” said the captain of the guard.

“I am no stranger. I am Brother Aleksandr,” said Sasha. “I have returned to Dmitrii Ivanovich, accompanying the holy father Sergei Radonezhsky.”

The captain scowled. “The Grand Prince ordered you brought to him when you arrived.”

Vasya bit her lip. Smoothly, Sasha said, “I will go to the Grand Prince, in due course. But the holy father must go first to the monastery, to rest and say prayers of thanks for his safe arrival.” Vasya’s hands were slippery on the lead-rope of the horse.

“The holy father may go where he chooses,” said the captain flatly. “But to the Grand Prince you will go, according to orders. I will have men escort you. The Grand Prince has taken advice, and he does not trust you.”

   “Who has advised him?” Sasha demanded.

“The wonder-worker,” said the gate-guard, and a little emotion entered his flat voice. “Father Konstantin Nikonovich.”

The Bear knows we are coming now, Morozko had said to Sergei and Sasha, as they made their way along the Moskva toward the city in the sweltering afternoon. It is possible you will be delayed at the gate. If so—

Vasya could scarcely breathe around the panic in her throat. But she managed to mutter to the pack-horse at her side: “Rear!”

The creature broke into a frenzy of heavy-limbed bucking. Next moment, Sasha’s battle-trained Tuman reared up as well, lashing out with her fore-hooves. Rodion’s horse too began capering heavily, right at the gate, and then Sergei raised his voice, rich and full despite his age, to say, “Come, Brother, let us all pray—” just as Tuman kicked one of the guards. When the confusion was at its height, Vasya slipped through the gate, Morozko in her wake.

Forget. Just like that other night on this same river. Forget that they could see her. Of course, the guards might not have seen her even without magic, so effectively had the three monks drawn all eyes.

She waited in the shadow of the gate. Waited for Sasha to come through with Sergei, so that she could follow them, invisibly, to the Grand Prince’s palace, be let in with them, unseen, then go and steal the bridle.

“Am I an utter fool, brother?” asked a familiar voice. Somewhere in its light tones was the clashing of armies, the screaming of men. The Bear stood in the shadow of the gate and seemed to have grown since the last time she saw him, as though nourished by the miasma of fear and sickness swirling about Moscow. “The city is mine,” he said. “What do you expect to do, coming here like a ghost in the company of a pack of monks? Betray me to the new religion? See me exorcised? No, I am stronger. You won’t have a pleasant prison of forgetfulness this time; it will be chains and long darkness. After I kill her and make her my servant in front of you.”

Morozko didn’t speak. He had a knife of ice, though the blade dripped water when it moved. His eyes met hers once, wordless.

She ran.

“Witch!” shouted the Bear, in the voice that men could hear. “Witch, there is a witch there!” Heads began to turn; then his voice was cut off abruptly. Morozko had flung his knife at his brother’s throat; the Bear had slammed it aside and then the two were grappling like wolves, invisible in the dust.

   Vasya fled, heart hammering in her throat, effacing herself in the shadow of buildings.

SHE TRIED NOT TO THINK of what was happening behind her; Sasha and Sergei set to distract Dmitrii, Morozko holding off the Bear.

The rest was up to her.

If it comes to it, I cannot keep him distracted forever, Morozko had said. Until sunset, not longer. And by sunset it won’t matter. He will have the dead, he will have the power of men’s fears, that rise in the dark. He must be bound by sunset, Vasya.

So she ran now, the sweat smarting in her eyes. The gazes of chyerti fell on her like a hail of stones, but she did not turn to see. People went heavily about their business, gasping and sweat-soaked, holding sachets of dried flowers to ward off sickness, paying little heed to a single gawky boy. A dead man lay huddled in a corner between two buildings, flies in his open eyes. Vasya swallowed nausea and ran on. With every step she had to fight down panic at being in Moscow again, and alone. Every sound, every smell, every turn of the streets brought back paralyzing memories; she felt like a girl in a nightmare, trying to run through clinging mud.

The gates of the palace of Serpukhov had been reinforced and reinforced again; spikes of wood lined the top, and there were guards on the gate. She paused, still fighting that stomach-clenching dread, wondering how she was going to—

A voice spoke from the wall-top. She had to look three times before she saw the speaker. It was Olga’s dvorovoi. He reached his two hands down to her. “Come,” he whispered. “Hurry, hurry.”

When she caught the outstretched hands of the dvorovoi, she found them strangely solid. Olga’s house-spirits had been little more than mist, before. But now the chyert’s hands pulled strongly. Vasya scrabbled for purchase, got a hand up to the top of the wall and pulled herself over.

   She dropped to the ground on the other side and found a brassy, silent dooryard, with only a few servants moving slowly. She breathed, groped for the forgetfulness that kept them from seeing her. She could barely manage it. Just there, Solovey had…

“I must speak to Varvara,” Vasya said to the dvorovoi, between clenched teeth.

But the dvorovoi had her by the hand, and was hustling her in the direction of the bathhouse. “You must see our lady,” he said.
