Scrabbling to one knee, he saw that the Red Bull had herded the unicorn almost to the beginning of the trees. If she would only try one more time to escape – but she was the Bull's and not her own. The magician had one glimpse of her, pale and lost between the pale horns, before the wild red shoulders surged across his sight. Then, swaying and sick and beaten, he closed his eyes and let his hopelessness march through him, until something woke somewhere that had wakened in him once before. He cried aloud, for fear and joy.

What words the magic spoke this second time, he never knew surely. They left him like eagles, and he let them go; and when the last one was away, the emptiness rushed back with a thunderclap that threw him on his face. It happened as quickly as that. This time he knew before he picked himself up that the power had been and gone.

Ahead, the Red Bull was standing still, nosing at something on the ground. Schmendrick could not see the unicorn. He went forward as fast as he could, but it was Molly who first drew near enough to see what the Bull was sniffing. She put her fingers in her mouth, like a child.

At the feet of the Red Bull there lay a young girl, spilled into a very small heap of light and shadow. She was naked, and her skin was the color of snow by moonlight. Fine tangled hair, white as a waterfall, came down almost to the small of her back. Her face was hidden in her arms.

"Oh," Molly said. "Oh, what have you done?" and, heedless of any danger, she ran to the girl and knelt beside her. The Red Bull raised his huge, blind head and swung it slowly in Schmendrick's direction. He seemed to be waning and fading as the gray sky grew light, though he still smoldered as savagely bright as crawling lava. The magician wondered what his true size was, and his color, when he was alone.

Once more the Red Bull snuffled at the still form, stirring it with his freezing breath. Then, without a sound, he bounded away into the trees and was gone from sight in three gigantic strides. Schmendrick had a last vision of him as he gained the rim of the valley: no shape at all, but a swirling darkness, the red darkness you see when you close your eyes in pain. The horns had become the two sharpest towers of old King Haggard's crazy castle.

Molly Grue had taken the white girl's head onto her lap, and was whispering over and over, "What have you done?" The girl's face, quiet in sleep and close to smiling, was the most beautiful that Schmendrick had ever seen. It hurt him and warmed him at the same time. Molly smoothed the strange hair, and Schmendrick noticed on the forehead, above and between the closed eyes, a small, raised mark, darker than the rest of the skin. It was neither a scar nor a bruise. It looked like a flower.

"What do you mean, what have I done?" he demanded of the moaning Molly. "Only saved her from the Bull by magic, that's what I've done. By magic, woman, by my own true magic!" Now he was helpless with delight, for he wanted to dance and he wanted to be still; he shook with shouting and speeches, and yet there was nothing that he wanted to say. He ended by laughing foolishly, hugging himself until he gasped, and sprawling down beside Molly as his legs let go.

"Give me your cloak," Molly said. The magician beamed at her, blinking. She reached over and ungently pulled the shredded cloak from his shoulders. Then she wrapped it around the sleeping girl, as much as it would wrap. The girl shone through it like the sun through leaves.

"Doubtless you are wondering how I plan to return her to her proper shape," Schmendrick offered. "Wonder not. The power will come to me when I need it – I know that much now. One day it will come when I call, but that time is not yet." Impulsively he seized Molly Grue, hugging her head in his long arms. "But you were right," he cried, "you were right! It is there, and it is mine!"

Molly pulled away from him, one cheek roughed red and both ears mashed. The girl sighed in her lap, ceased to smile, turned her face from the sunrise. Molly said, "Schmendrick, you poor man, you magician, don't you see -"

"See what? There's nothing to see." But his voice was suddenly hard and wary, and the green eyes were beginning to be frightened. "The Red Bull came for a unicorn, so she had to become something else. You begged me to change her – what is it frets you now?"

Molly shook her head in the wavering way of an old woman. She said, "I didn't know you meant to turn her into a human girl. You would have done better -" She did not finish, but looked away from him. One hand continued to stroke the white girl's hair.

"The magic chose the shape, not I," Schmendrick answered. "A mountebank may select this cheat or that, but a magician is a porter, a donkey carrying his master where he must. The magician calls, but the magic chooses. If it changes a unicorn to a human being, then that was the only thing to do." His face was fevered with an ardent delirium which made him look even younger. "I am a bearer," he sang. "I am a dwelling, I am a messenger -"

"You are an idiot," Molly Grue said fiercely. "Do you hear me? You're a magician, all right, but you're a stupid magician." But the girl was trying to wake, her hands opening and closing, and her eyelids beating like birds' breasts. As Molly and Schmendrick looked on, the girl made a soft sound and opened her eyes.

They were farther apart than common, and somewhat deeper set, and they were as dark as the deep sea; and illuminated, like the sea, by strange, glimmering creatures that never rise to the surface. The unicorn could have been transformed into a lizard, Molly thought, or into a shark, a snail, a goose, and somehow still her eyes would have given the change away. To me, anyway. I would know.

The girl lay without moving, her eyes finding herself in Molly's eyes, and in Schmendrick's. Then, in one motion, she was on her feet, the black cloak falling back across Molly's lap. For a moment she turned in a circle, staring at her hands, which she held high and useless, close to her breast. She bobbed and shambled like an ape doing a trick, and her face was the silly, bewildered face of a joker's victim. And yet she could make no move that was not beautiful. Her trapped terror was more lovely than any joy that Molly had ever seen, and that was the most terrible thing about it.

"Donkey," Molly said. "Messenger."

"I can change her back," the magician answered hoarsely. "Don't worry about it. I can change her back."

Shining in the sun, the white girl hobbled to and fro on her strong young legs. She stumbled suddenly and fell, and it was a bad fall because she did not know how to catch herself with her hands. Molly flew to her, but the girl crouched on the ground staring at her, and spoke in a low voice. "_What have you done to me?_" Molly Grue began to cry.

Schmendrick came forward, his face cold and wet, but his voice level. "I turned you into a human being to save you from the Red Bull. There was nothing else I could do. I will turn you to yourself again, as soon as I can."

"The Red Bull," the girl whispered. "Ah!" She was trembling wildly, as though something were shaking and hammering at her skin from within. "He was too strong," she said, "too strong. There was no end to his strength, and no beginning. He is older than I."

Her eyes widened, and it seemed to Molly that the Bull moved in them, crossing their depths like a flaming fish, and vanishing. The girl began to touch her face timidly, recoiling from the feel of her own features. Her curled fingers brushed the mark on her forehead, and she closed her eyes and gave a thin, stabbing howl of loss and weariness and utter despair.

"What have you done to me?" she cried. "I will die here!" She tore at the smooth body, and blood followed her fingers. "I will die here! I will die!" Yet there was no fear in her face, though it ramped in her voice, in her hands and feet, in the white hair that fell down over her new body. Her face remained quiet and untroubled.
