Without warning, the whole castle sang like a plucked string as the beast asleep at its root shifted his dire weight. The Lady Amalthea caught her balance easily, being well used to this, and said lightly, "The Red Bull. But why do you think I have come to steal the Bull? I have no kingdom to keep, and no wish for conquest. What would I do with him? How much does he eat?"

"Do not mock me!" the king answered. "The Red Bull is no more mine than the boy is, and he does not eat, and he cannot be stolen. He serves anyone who has no fear – and I have no more fear than I have rest." Yet the Lady Amalthea saw forebodings sliding over the long, gray face, scuttling in the shadows of brows and bones. "Do not mock me," he said. "Why will you play that you have forgotten your quest, and that I am to remind you of it? I know what you have come for, and you know very well that I have it. Take it, then, take it if you can – but do not dare to surrender now!" The black wrinkles were all on edge, like knives.

Prince Lнr was singing as he rode, though the Lady Amalthea could not yet hear the words. She said quietly to the king, "My lord, in all your castle, in all your realm, in all the kingdoms that the Red Bull may bring you, there is only one thing I desire – and you have just told me that he is not yours to give or to keep. Whatever it is you treasure that is not he, I truly wish you joy of it. Good day, Your Majesty."

She moved toward the tower stairway, but he stood in her way and she paused, looking at him with her eyes as dark as hoofprints in snow. The gray king smiled, and a strange kindness for him chilled her for an instant, for she suddenly fancied that they were somehow alike. But then he said, "I know you. I almost knew you as soon as I saw you on the road, coming to my door with your cook and your clown. Since then, there is no movement of yours that has not betrayed you. A pace, a glance, a turn of the head, the flash of your throat as you breathe, even your way of standing perfectly still – they were all my spies. You have made me wonder for a little while, and in my own way I am grateful. But your time is done."

He looked seaward over his shoulder, and suddenly stepped to the parapet with the thoughtless grace of a young man. "The tide is turning," he said. "Come and see it. Come here." He spoke very softly, but his voice suddenly held the crying of the ugly birds on the shore. "Come here," he said fiercely. "Come here, I won't touch you."

Prince Lнr sang:

The horrible head on his saddle was harmonizing in a kind of bass falsetto. The Lady Amalthea went to stand with the king.

The waves were coming in under the thick, swirling sky, growing as slowly as trees as they bulged across the sea. They crouched as they neared the shore, arching their backs higher and higher, and then sprang up the beach as furiously as trapped animals bounding at a wall and falling back with a sobbing snarl to leap again and again, claws caked and breaking, while the ugly birds yelled mournfully. The waves were gray and green as pigeons until they broke, and then they were the color of the hair that blew across her eyes.

"There," a strange, high voice said close to her. "There they are." King Haggard was grinning at her and pointing down to the white water. "There they are," he said, laughing like a frightened child, "there they are. Say that they are not your people, say that you did not come here searching for them. Say now that you have stayed all winter in my castle for love."

He could not wait for her answer, but turned away to look at the waves. His face was changed beyond believing: delight coloring the somber skin, rounding over the cheekbones, and loosening the bowstring mouth. "They are mine," he said softly, "they belong to me. The Red Bull gathered them for me, one at a time, and I bade him drive each one into the sea. What better place could there be to keep unicorns, and what other cage could hold them? For the Bull keeps guard over them, awake or asleep, and he daunted their hearts long ago. Now they live in the sea, and every tide still carries them within an easy step of the land, but they dare not take that step, they dare not come out of the water. They are afraid of the Red Bull."

Nearby, Prince Lнr sang, "Others may offer more than they can give, All that they have for as long as they live…" The Lady Amalthea closed her hands on the parapet and wished for him to come to her, for she knew now that King Haggard was mad. Below them lay the thin, sallow beach, and the rocks, and the rising tide, and nothing more.

"I like to watch them. They fill me with joy." The childish voice was all but singing. "I am sure it is joy. The first time I felt it, I thought I was going to die. There were two of them in the early morning shadows. One was drinking from a stream, and the other was resting her head on his back. I thought I was going to die. I said to the Red Bull, 'I must have that. I must have all of it, all there is, for my need is very great.' So the Bull caught them, one by one. It was all the same to the Bull. It would have been the same if I had demanded tumblebugs or crocodiles. He can only tell the difference between what I want and what I do not want."

He had forgotten her for the moment as he leaned over the low wall, and she might have fled the tower then. But she stayed where she was, for an old bad dream was waking all around her, though it was daylight. The tide shattered on the rocks and tumbled together again, and Prince Lнr rode along singing, "But I will love you as long as I can, And never ask if you love me."

"I suppose I was young when I first saw them," King Haggard said. "Now I must be old – at least I have picked many more things up than I had then, and put them all down again. But I always knew that nothing was worth the investment of my heart, because nothing lasts, and I was right, and so I was always old. Yet each time I see my unicorns, it is like that morning in the woods, and I am truly young in spite of myself, and anything can happen in a world that holds such beauty."

In the dream I looked down at four white legs, and felt the earth under split hoofs. There was a burning on my brow, as there is now. But there were no unicorns coming in on the tide. The king is mad. He said, "I wonder what will become of them when I am gone. The Red Bull will forget them immediately, I know, and be off to find a new master, but I wonder if they will take their freedom even then. I hope not, for then they will belong to me forever."

Then he turned to look at her again, and his eyes were as gentle and greedy as Prince Lнr's eyes became when he looked at her. "You are the last," he said. "The Bull missed you because you were shaped like a woman, but I always knew. How did you manage the change, by the way? Your magician couldn't have done it. I don't think he could turn cream into butter."

If she had let go of the parapet she would have fallen, but she answered him quite calmly, "My lord, I do not understand. I see nothing at all in the water."

The king's face shivered as though she were looking at him through fire. "Do you still deny yourself?" he whispered. "Do you dare deny yourself? Nay, that's as false and cowardly as though you were truly human. I'll hurl you down to your folk with my own hands if you deny yourself." He took a step toward her, and she watched him with her eyes open, unable to move.

The tumult of the sea filled her head, together with Prince Lнr's singing and the blubbering death wail of the man named Rukh. King Haggard's gray face hung over her like a hammer, muttering, "It must be so, I cannot be mistaken. Yet her eyes are as stupid as his – as any eyes that never saw unicorns, never saw anything but themselves in a glass. What cheat is this, how can it be? There are no green leaves in her eyes now."
