The young man came into the prelate’s presence, tall and pale and burning. His robe of dark stuff set off the beauty of his hair and eyes.

“Father Konstantin,” said Aleksei, “you are called to a task by God.”

Father Konstantin said nothing.

“A woman,” the Metropolitan continued, “the Grand Prince’s own sister, has sent a messenger begging our help. Her village flock is without a shepherd.”

The young man’s face did not change.

“You are the very man to go and minister to the lady and her family,” Aleksei finished, smiling with an air of studied benevolence.

“Batyushka,” said Father Konstantin. His voice was so deep it was startling. The servant at Aleksei’s elbow squeaked. The Metropolitan narrowed his eyes. “I am honored. But already I have my work among the people of Moscow. And my icons, that I have painted for the glory of God, they are here.”

“There are many of us to tend to the people of Moscow,” replied the Metropolitan. The young priest’s voice was soothing and unnerving at the same time, and Aleksei watched him warily. “And no one at all for those poor lost souls in the wilderness. No, no, it really must be you. You will leave in three weeks.”

Pyotr Vladimirovich is a sensible man, thought Aleksei. Three seasons in the north will kill this upstart, or at least fade that oh-so-dangerous loveliness. Better than killing him now, lest the people take his flesh for relics and make him a martyr.

Father Konstantin opened his mouth. But he caught the Metropolitan’s eye, which was hard as flint. The guards waited at every hand, and more in the anteroom, with long scarlet pikes. Konstantin bit back whatever he had wanted to say.

“I am sure,” said Aleksei softly, “that you have much to do before your departure. God be with you, my son.”

Konstantin, white-faced and biting his red lip, bent his head stiffly and turned on his heel. His heavy robe rippled and snapped behind him as he left the room.

“Good riddance,” muttered Aleksei, though he was uneasy still. He dashed kvas into a cup and tossed it cold down his throat.

AT HIGH SUMMER, the roads were grass-grown and dry. The mild sun loved the sweet-smelling earth, and soft rains scattered flowers in the forest. But Father Konstantin saw none of it; he rode beside Anna’s messenger in a white-lipped rage. His fingers ached for his brushes, for his pigments and wood panels, for his cool, quiet cell. Most of all he ached for the people, for their love and hunger and half-frightened rapture, for the way their hands stretched out to his. Devils take the meddling Metropolitan. And now he was exiled, for no other reason than that people preferred him.

Well. He’d train some village boy, see him ordained, and then be free to return to Moscow. Or perhaps go farther south, to Kiev, or west to Novgorod. The world was wide, and Konstantin Nikonovich would not be left to rot on some farm in the woods.

Konstantin spent a week fuming, and then natural curiosity took over. The trees grew steadily larger as they rode deeper into the wild lands: oaks of giant girth and pines tall as the domes of churches. The bright meadows grew sparser as the forest drew in on either side; the light was green and gray and purple, and the shadows lay thick as velvet.

“What is it like, the land of Pyotr Vladimirovich?” Konstantin asked his companion one morning. The messenger started. They had been riding a week, and the handsome priest had hardly opened his lips except to eat his meals.

“Very beautiful, Batyushka,” the man replied respectfully. “Trees fine as cathedrals, and bright streams on all sides. Flowers in summer, fruit in autumn. Cold in winter, though.”

“And your master and mistress?” asked Konstantin, curious despite himself.

“A good man is Pyotr Vladimirovich,” said the man, warmth creeping into his voice. “Hard sometimes, but fair, and his folk never go wanting.”

“And your mistress?”

“Oh, a good woman; a good woman. Not like the mistress that was, but a good woman all the same. I know no harm of her.” He shot Konstantin a furtive glance as he spoke, and Father Konstantin wondered what it was that the messenger had not said.

THE DAY THE PRIEST ARRIVED, Vasya was sitting in a tree talking to a rusalka. Once, Vasya had found such conversations disconcerting, but now she had gotten used to the woman’s green-skinned nakedness and the constant drip of water from her pale, weedy hair. The sprite was sitting on a thick limb with catlike nonchalance, steadily combing her long tresses. Her comb was the rusalka’s greatest treasure, for if her hair dried, she would die; but the comb could conjure water anywhere. When she looked closely, Vasya could see the water flowing from the comb’s teeth. The rusalka had an appetite for flesh; she would snatch fawns drinking in her lake at dawn, and sometimes the young men who swam there at midsummer. But she liked Vasilisa.

It was late afternoon, and the light of the long northern days shone down on the two, bringing out the radiance in Vasya’s hair and fading the rusalka to a greenish, woman-shaped ghost. The water-spirit was old as the lake itself, and sometimes she looked wonderingly on Vasya, the brash child of a newer world.

They had become friends under strange circumstances. The rusalka had stolen a village boy. Vasya, seeing the youth vanish, gurgling, and the flash of green fingers, had dived into the lake after him. Child though she was, she blazed with the strength of her own mortality and was a match for any rusalka. She seized the boy and dragged him back into daylight. They made it safe to shore, the boy bruised and spitting water, staring at Vasya with equal parts gratitude and terror. He tore away from her and ran for the village as soon as he felt the earth under his feet.

Vasya had shrugged and followed, wringing the water from her braid. She wanted her soup. But late in the long spring twilight, when each leaf and blade of grass stood out black against the blue-tinged air, Vasya had returned to the lake. She sat down on the verge, toes in the water.

“Did you wish to eat him?” she asked the water conversationally. “Can you not find other meat?”

There was a small leaf-filled silence.

Then—“No,” said a rippling voice. Vasya sprang to her feet, eyes flicking through the foliage. It was luck more than anything else that her glance lit on the sinuous outlines of a naked woman. The rusalka crouched on a limb, a glimmering white thing clutched in one hand.

“Not meat,” the creature had said with a shudder, hair scudding like wavelets over her skin. “Fear—and desire—not that you know anything of either. It flavors the water and nourishes me. Dying, they know me for who I am. Otherwise I’d be no more than lake and tree and waterweed.”

“But you kill them!” said Vasya.

“Everything dies.”

“I will not let you slay my people.”

“Then I will disappear,” replied the rusalka, without inflection.

Vasya thought for a moment. “I know you’re here. I can see you. I am not dying, and I am not afraid—but—I can see you. I could be your friend. Is that enough?”

The rusalka was looking at her curiously. “Perhaps.”

And true to her word, Vasya would come looking for the water-spirit, and in spring she threw flowers into the lake, and the rusalka did not die.

In return, the rusalka taught Vasya to swim as very few could, and to climb trees like a cat, and so it was that the two found themselves together, lounging on a limb overlooking the road, as Father Konstantin approached Lesnaya Zemlya.
