The roof, when we reached it, was not flat; and the pitch was great enough for me to fear falling at every step. Its hard, uneven surface seemed to be of tiles - once one loosened, and I heard it grating and clattering against the others until it fell over the edge and smashed on the uneven slabs below.

When I was an apprentice and too young to be entrusted with any but the most elementary tasks, I was given a letter to take to the witches' tower, across the Old Court from our own. (I learned much later that there was a good reason for selecting only boys well below the age of puberty to carry the messages our proximity to the witches required.) Now, when I know of the horror our own tower inspired not only in the people of the quarter but to an equal or greater degree in the other residents of the Citadel itself, I find a flavor of quaint naivete in the recollection of my own fear; yet to the small and unattractive boy I was, it was very real. I had heard terrible stories from the older apprentices, and I had seen that boys unquestionably braver than I were afraid. In that most gaunt of all the Citadel's myriad towers, strangely colored lights burned by night. The screams we heard through the ports of our dormitory came not from some underground examination room like our own, but from the highest levels; and we knew that it was the witches themselves who screamed thus and not their clients, for in the sense we used that word, they had none. Nor were those screams the howlings of lunacy and the shrieks of agony, as ours were.

I had been made to wash my hands so they would not soil the envelope, and I was very conscious of their dampness and their redness as I picked my way among the puddles of freezing water that dotted the courtyard. My mind conjured up a witch who should be immensely dignified and humiliating, who would not shrink from punishing me in some particularly repulsive way for daring to carry a letter to her in red hands and would send me back with a scornful report to Master Malrubius as well.

I must have been very small indeed: I had to jump to reach the knocker. The smack of the witches' deeply worn doorstep against the thin soles of my shoes remains with me still.

"Yes?" The face that looked into mine was hardly higher than my own. It was one of those - outstanding of its kind among all the hundreds of thousands of faces I have seen - that are at once suggestive of beauty and disease. The witch to whom it belonged seemed old to me and must actually have been about twenty or a little less; but she was not tall, and she carried herself in the bent-backed posture of extreme age. Her face was so lovely and so bloodless that it might have been a mask carved in ivory by some master sculptor.

Mutely, I held up my letter.

"Come with me," she said. Those were the words I had feared, and now that they had actually been given voice, they seemed as inevitable as the procession of the seasons.

I entered a tower very different from our own. Ours was oppressively solid, of plates of metal so closely fitted that they had, ages ago, diffused into one another to become one mass, and the lower floors of our tower were warm and dripping. Nothing seemed solid in the witches' tower, and few things were. Much later, Master Palaemon explained to me that it was far older than most other parts of the Citadel, and had been built when the design of towers was still little more than the imitation in inanimate materials of human physiology, so that skeletons of steel were used to support a fabric of flimsier substances. With the passing of the centuries, that skeleton had largely corroded away - until at last the structure it had once stiffened was held up only by the piecemeal repairs of past generations. Oversized rooms were separated by walls not much thicker than draperies; no floor was level, and no stair straight; each banister and railing I touched seemed ready to come off in my hand. Gnostic designs in white, green, and purple had been chalked on the walls, but there was little furniture, and the air seemed colder than that outside.

After climbing several stairs and a ladder lashed together from the unpeeled saplings of some fragrant tree, I was ushered into the presence of an old woman who sat in the only chair I had yet seen there, staring through a glass tabletop at what appeared to be an artificial landscape inhabited by hairless, crippled animals. I gave her my letter and was led away; but for a moment she had glanced at me, and her face, like the face of the young-old woman who had brought me to her, has of course remained graven in my mind.

I mention all this now because it seemed to me, as I laid Jolenta on the tiles beside the fire, that the women who crouched over it were the same. It was impossible; the old woman to whom I had handed my letter was almost certainly dead, and the young one (if she were still living) would be changed beyond recognition, as I was myself. Yet the faces that turned toward me were the faces I recalled. Perhaps there are but two witches in the world, who are born into it again and again.

"What is the matter with her?" the younger woman asked, and Dorcas and I explained as well as we could.

Long before we finished, the older one had Jolenta's head in her lap and was forcing wine from a clay bottle into her throat. "It would harm her if it were strong to harm," she said. "But this is three parts pure water. Since you do not wish to see her die, you are fortunate, possibly, to have come across us so. Whether she is also fortunate, I cannot say."

I thanked her, and inquired where the third person who had been at their fire had gone.

The old woman sighed, and stared at me for a moment before returning her attention to Jolenta.

"There were only the two of us," the younger woman said. "You saw three?"

"Very clearly, in the firelight. Your grandmother - if that is who she is - looked up and spoke to me. You and whoever was with you lifted your heads, then bowed them again."

"She is the Cumaean."

I had heard the word before, but for a moment I could not remember where, and the younger woman's face, immobile as an oread's in a picture, gave me no clue.

"The seeress," Dorcas supplied. "And who are you?"

"Her acolyte, My name is Merryn. It is significant, possibly, that you, who are three, saw three of us at the fire, while we who are two at first saw but two of you." She looked to the Cumaean as if for confirmation, and then, as if she had received it, back to us, though I saw no glance pass between them.

"I'm quite sure I saw a third person who was larger than either of you," I said.

"This is a strange evening, and there are those who ride the night air who sometimes choose to borrow a human seeming. The question is why such a power would wish to show itself to you."

The effect of her dark eyes and serene face was so great that I think I might have believed her if it had not been for Dorcas, who suggested with an almost imperceptible movement of her head that the third member of the group about the fire might have escaped our observation by crossing the roof and hiding on the farther side of the ridge.

"She may live," the Cumaean said without lifting her gaze from Jolenta's face. "Though she does not wish it."

"It's a good thing for her that the two of you had so much wine," I said.

The old woman did not rise to the bait, saying only, "Yes, it is. For you and possibly even for her."

Merryn picked up a stick and stirred the fire. "There is no death."

I laughed a little, mostly, I think, because I was no longer quite so worried about Jolenta. "Those of my trade think otherwise."

"Those of your trade are mistaken."

Jolenta murmured, "Doctor?" It was the first time she had spoken since morning.

"You do not need a physician now," Merryn said. "Someone better is here."

The Cumaean muttered, "She seeks her lover."

"Who is not this man in fuligin then, Mother? I thought he seemed too common for her."

"He is but a torturer. She seeks a worse man."

Merryn nodded to herself, then said to us, "You will not wish to move her farther tonight, but we must ask that you do. You will find a hundred better camping places on the other side of the ruins, and it would be dangerous for you to stay here."

"A danger of death?" I asked. "But you tell me there is none - so if I believe you, why should I fear? And if I cannot believe you, why should I believe you now?" Nevertheless, I rose to go.

The Cumaean looked up. "She's right," she croaked. "Though she does not know it, and only speaks by rote like a starling in a cage. Death is nothing, and for that reason you must fear it. What is more to be feared?"

I laughed again. "I can't argue with someone as wise as you. And because you gave us what help you could, we will go now because you wish it."

The Cumaean permitted me to take Jolenta from her, but said, "I do not wish it. My acolyte still believes the universe hers to command, a board where she can move counters to form whatever patterns suit her. The Magi see fit to number me among themselves when they write their short roll, and I should lose my place on it if I did not know that people like ourselves are only little fish, who must swim with unseen tides if we are not to exhaust ourselves without finding sustenance. Now you must wrap this poor creature in your cloak and lay her by my fire. When this place passes out of the shadow of Urth, I will look to her wound again."

I remained standing, holding Jolenta, uncertain whether we should go or stay. The Cumaean's intentions seemed friendly enough, but her metaphor had carried an unpleasant reminder of the undine; and as I studied her face I had come to doubt that she was an old woman at all, and to recall only too clearly the hideous faces of the cacogens who had removed their masks when Baldanders had rushed among them.

"You shame me, Mother," Merryn said. "Shall I call to him?"

"He has heard us. He will come without your call."

She was right. I already detected the scrape of boots on the tiles of the other side of the roof.

"You are alarmed. Would it not be better to put down the woman as I instructed you, so you might take up your sword to defend your paramour? But there will be no need."

By the time she had finished speaking, I could see a tall hat and a big head and broad shoulders silhouetted against the night sky. I laid Jolenta near Dorcas and drew Terminus Est.

"No need of that," a deep voice said. "No need at all, young fellow. I'd have come out sooner to renew our acquaintance, but I didn't know the Chatelaine here wanted it. My master - and yours - sends his greetings." It was Hildegrin.

Chapter 31

THE CLEANSING

"You may tell your master I delivered his message," I said.

Hildegrin smiled. "And have you a message to return, armiger? Remember, I'm from the quercine penetralia."

"No," I said. "None."

Dorcas looked up. "I do. A person I met in the gardens of the House Absolute told me I would encounter someone who identified himself thus, and that I was to say to him, 'When the leaves are grown, the wood is to march north.'"

Hildegrin laid a finger beside his nose. "All the wood? Is that what he said?"

"He gave me the words I have already recited to you, and nothing more."

"Dorcas," I asked, "why didn't you tell me this?"

"I've hardly had an opportunity to talk to you alone since we met at the crossing of the paths. And besides, I could see it was a dangerous thing to know. I couldn't see any reason to put that danger on you. It was the man who gave Dr. Talos all that money who told me. But he didn't give Dr. Talos the message - I know because I listened when they talked. He only said that he was your friend, and told me."

"And told you to tell me."

Dorcas shook her head.

Hildegrin's thick-throated, chuckle might almost have come from underground. "Well, it don't hardly matter now, does it? It's been delivered, and for myself I don't mind tellin' you I wouldn't have minded if it had waited a little longer. But we're all friends here, except maybe for the sick girl, and I don't think she can hear what's said, or understand what we're talkin' about if she could. What did you say her name was? I couldn't hear you too clear when I was over there on the other side."

"That was because I didn't say it at all," I told him. "But her name is Jolenta." As I pronounced Jolenta, I looked at her and seeing her in the firelight realized she was Jolenta no longer - nothing of the beautiful woman Jonas had loved remained in that haggard face.

"And a bat bite did it? They've grown uncommon strong lately then. I've been bit a couple of times myself." I looked at Hildegrin sharply, and he added, "Oh yes, I've seen her before, young sieur, as well as yourself and little Dorcas. You didn't think I let you and that other gal leave, the Botanic Gardens alone, did you? Not with you talkin' of goin' north and fightin' a officer of the Septentrions. I saw you fight and saw you take that fellow's head off - I helped to catch him, by the bye, because I thought he might be from the House Absolute for true - and I was in the back of the people that watched you on the stage that night. I didn't lose you till the affair at the gate the next day. I seen you and I seen her, though there's not much left of her now except the hair, and I think even that's changed."

Merryn asked the Cumaean, "Shall I tell them, Mother?"

The old woman nodded. "If you can, child."

"She has been imbued with a glamour that rendered her beautiful. It is fading fast now because of the blood she lost and because she has had a great deal of exercise. By morning only traces will remain."

Dorcas drew back, "Magic, you mean?"

"There is no magic. There is only knowledge, more or less hidden."

Hildegrin was staring at Jolenta with a thoughtful expression.

"I didn't know looks could be changed so much. That might be useful, that might. Can your mistress do it?"

"She could do much more than this, if she willed it."

Dorcas whispered, "But how was this done?"

"There have been substances drawn from the glands of beasts added to her blood, to change the pattern in which her flesh was deposited. Those gave her a slender waist, breasts like melons, and so on. They may have been used to add calf to her legs as well. Cleaning and the application of healthening broths to the skin freshened her face. Her teeth were cleaned too, and some were ground down and given false crowns - one has fallen away now, if you'll look. Her hair was dyed, and thickened by sewing threads of colored silk into her scalp. No doubt much body hair was killed as well, and that at least will remain so. Most important, she was promised beauty while entranced. Such promises are believed with faith greater than any child's, and her belief compelled yours."
