Pyotr could not have said, exactly, what about this man was strange, except that he had a sort of—stillness, striking amid the bustle. His clothes were fit for a prince, his boots richly embroidered. A knife hung at his belt, white gems sparkling at the hilt. His black curls were uncovered, odd for any man, and more so as it was white winter—brilliant sky and snow groaning underfoot. He was clean-shaven—something all but unheard-of among the Rus’—and Pyotr, from a distance, could not tell if he was old or young.

Pyotr realized he was staring, and turned away. But he was curious. The jewel-merchant said confidingly:

“You are curious about that man? You are not alone. He comes sometimes, to the market, but no one knows who his people are.”

Pyotr was skeptical. The merchant smirked. “Truly, gospodin. He is never seen in church, and the bishop wants him stoned for idolatry. But he is rich, and he always brings the most marvelous things to trade. So the prince keeps the Church quiet, and the man comes and goes away again. Perhaps he is a devil.” This was tossed off, half-laughing, but then the merchant frowned. “Never once have I seen him in the springtime. Always, always he comes in winter, at the turning of the year.”

Pyotr grunted. He himself was quite open to the possibility of devils, but he was not convinced that they would stroll about markets—summer or winter—dressed in princely raiment. He shook his head, indicated a bracelet, and said, “This is rotten stuff; already the silver is green round the edges.” The merchant protested, and the two settled to chaffering in earnest, forgetting all about the black-haired stranger.

THE STRANGER IN QUESTION halted before a market-stall, not more than ten paces from where Pyotr stood. He ran thin fingers over a heap of silk brocade. His hands alone could tell him the quality of the wares; he paid only cursory attention to the cloth before him. His pale eyes flicked here and there, about the crowded market.

The cloth-seller watched the stranger with a sort of obsequious wariness. The merchants knew him; a few thought he was one of them. He had brought marvels to Moscow before: weapons from Byzantium, porcelain light as morning air. The merchants remembered. But this time the stranger had another purpose; else he’d never have come south. He did not like cities, and it was a risk to cross the Volga.

The flashing colors and voluptuous weight of the fabric suddenly seemed tedious, and after a moment, the stranger abandoned the cloth and strode across the square. His horse stood on the south side, chewing wisps of hay. A rheumy old man stood at her head, pale and thin and oddly insubstantial, though the white mare was magnificent as a rearing mountain, and her harness was tooled and chased with silver. Men stared at her with admiration as they passed. She flicked her ears like a coquette, drawing a faint smile from her rider.

But suddenly a big man with cracked fingernails appeared out of the crowd and snatched the horse’s rein. Her rider’s face darkened. Though his pace did not quicken—there was no need—a cold wind rippled across the square. Men snatched for hats and loosened garments. The would-be thief flung himself into the mare’s saddle and dug in his heels.

But the mare did not move. Neither did her groom, oddly enough; he neither shouted nor raised a hand. He merely watched, an unreadable look in his sunken eyes.

The thief lashed the mare’s shoulder. She did not stir a hoof, only swished her tail. The thief hesitated a bewildered instant, and then it was too late. The mare’s rider strode up and wrenched him out of the saddle. The thief might have screamed, but found his throat frozen. Gasping, he groped for the wooden cross at his throat.

The other smiled, without humor. “You have trespassed on what is mine; do you think faith will save you?”

“Gosudar,” the thief stammered, “I did not know—I thought—”

“That such as I do not walk in the places of men? Well, I go where I will.”

“Please,” choked the thief. “Gosudar, I beg—”

“Don’t mewl,” said the stranger, with cool humor. “And I will leave you awhile, to walk free in the sun. However”—the quiet voice dropped lower and the laughter drained out of it like water from a smashed cup—“you are marked, you are mine, and one day I shall touch you again. You will die.” The thief choked out a sobbing breath, then found himself suddenly alone, a stinging like fire in his arm and throat.

Already in the saddle, though no one had seen him mount, the stranger wheeled and sent his horse through the crush. The horse’s groom bowed once and melted into the crowd.

The mare was light and swift and sure. Her rider’s anger quieted as he rode.

“The signs led me here,” said the man to his horse. “Here, to this stinking city, when I should not have left my own lands.” He had been in Moscow a month already, searching, tireless, face after face. “Well, signs are not infallible,” he said. “The witch’s daughter is hidden from me, and her child is long gone. The hour might have passed; the hour might never come.”

The mare slanted an ear back at her rider. His lips firmed. “No,” he said. “Am I so easily defeated?”

The mare went on at a steady canter. The man shook his head. He was not yet beaten; he held the magic trembling in his throat, in the hollow of his hand, ready. His answer lay somewhere in this miserable wooden city, and he would find it.

He turned the mare west, urging her into a long-striding gallop. The coolness among the trees would clear his head. He was not defeated.

Not yet.

THE REEK OF MEAD and dogs, dust and humanity, greeted the stranger when he arrived at the Grand Prince’s feast. Ivan’s boyars were big men used to battle, and to carving life out of the land of frost. The stranger was not so large as even the smallest. But no one, not even the bravest—or the drunkest—could meet his eyes, and no one offered him challenge. The stranger took a place at the high table and drank his honey-wine unmolested. The silver embroidery on his kaftan shone in the torchlight. One of the princess’s waiting-women sat beside him, gazing up through her long lashes.

Lent was near and the feasting was raucous. But—It is all the same here, thought the stranger. All these dim, busy faces. Sitting amid the din and the stink, he felt, for the first time—not despair, perhaps, but the beginning of resignation.

It was then that a man walked into the hall with two grown boys. The three took places at the high table. The older man was quite ordinary, his clothes of good quality. His elder son swaggered and the younger walked softly, his glance cool and grave. Perfectly ordinary.

And yet.

The stranger’s gaze shifted. With the three came a curling breath of wind, a wind out of the north. In the space between one breath and the next, the wind told him a tale: of life and death together, of a child born with the failing year.

“The blood holds, brother,” he whispered. “She lives, and I was not mistaken.” His face was triumphant. He returned to the table (though indeed he had never moved), and smiled with sudden delight into the eyes of the woman beside him.

PYOTR HAD ALL BUT forgotten the stranger in the market. But when he came that night to the Grand Prince’s table, he was quickly reminded, for the same stranger was sitting among the boyars, beside one of the princess’s waiting-women. She was staring up at him, her painted eyelids trembling like wounded birds.
