"Someone told me," Duncan said, "that they are no horde at all; they really are a swarm. What could be meant by that?"

"I do not really know," said Scratch. "I have, you must understand, no real knowledge of them. It's only what I've heard."

"I realize that. But about a swarm. Prior to being told that they were more like a swarm than horde, I had talked with a venerable bee master and he talked of swarming bees. In this wise, could there be some connection?"

"There is one thing," said Scratch, "although it was a short conversation only that I chanced to overhear. It might, just possibly, bear on this swarming matter."

"Please go on," said Duncan. "Tell me what it was."

"At those times," said Scratch, "when the Horde is in the process of devastating an area, in the way it has devastated northern Britain, the members of the Horde at times are prone to come together, to form a sort of living mass. Perhaps like unto a swarm of bees. The ones who talked of this, having heard of it from a few widely separated and isolated observations, were very puzzled by the reported action. At other times, it appears, the individual members of the Horde, when there is no devastation going on, seem to work alone or in small parties, only a few of them together. But when they are about a devastation, they do collect, or so observers say, into a massive swarm…"

"Now, wait a minute," Duncan said. "I think there might be a clue to that. A learned man told me, not long ago, that they devastated an area to make themselves secure so they can engage in a rejuvenation process, a retreat of sorts, he said, as fathers of the church sometimes hold retreats. Do you suppose…"

"You know," said Scratch excitedly, "you may have something there. I have never heard of their rejuvenation rites. But that could well be it. A coming together of the entire community of Evil, a close coming together, a personal contact, one to one, and from that contact they might gain an unknown strength, a renewing of themselves. What do you think? It sounds reasonable to me."

"That had been my thought. I'm glad you share it with me."

"That might explain the swarming."

"I think it could. Although there are so many factors, so many things of which we have no understanding and perhaps never will."

"That is true," said Scratch, "but it's a good hypothesis. One that could be worked on. You talked with Cuthbert. What had he to say of it?"

"We did not talk about the swarming. At the time I did not know of it and if he did, he did not mention it. I brought up the rejuvenation theory, but he seemed to think little of it. He said the Horde was frightened of something, probably was getting together to move against it, but for some reason had become confused. Tell me something, Scratch. If you were forced to take sides in this matter, if there were no way in which you could avoid taking sides, which side would you choose?"

The demon jiggled his hoof up and down and the chain clanked. "This may sound strange to you," he said, "but if forced to take a stand I'd stand in with you humans. My heritage may be evil, but it's a human evil, or at least an earthly evil. I could not stomach associating with an alien evil. I'd not know them and they'd not know me and I'd be uncomfortable with them. Evil may be evil, but there are various kinds of it and they can't always come together."

Steps sounded on the stairs coming down from the balcony into the reception hail, and Duncan looked around. Still dressed in her green gown, Diane seemed to be floating down the stairs. Only the tapping of her sandals betrayed her walking.

Duncan got off the bench and Scratch also clambered off to stand stiffly beside him.

"Scratch," asked Diane, "what are you doing off your pillar?"

"Milady," Duncan told her, "I asked him to come down and sit with me. It was more comfortable for me. That way I did not need to stand, craning up my head to look at him."

"Has he been pestering you?"

"Not at all," said Duncan. "We've had a pleasant talk."

"I suppose," said Scratch, "I'd best get up again."

"Wait a second," Duncan said, "and I'll lend you a hand." He reached down and hoisted the demon so he could catch hold with his crippled hands and scramble back atop the pillar.

"It was good talking with you," Duncan said. "Thanks for giving me your time."

"That is gracious of you, my lord. We will talk again?"

"Most assuredly," said Duncan.

The demon squatted atop the pillar and Duncan turned back to Diane. She was standing in the entrance waiting for him.

"I had thought," she said, "we might take a turn around the grounds. I'd like to show them to you."

"I'd be delighted," said Duncan. "It is kind of you."

He offered her his arm and they went down the stairs together.

"How is Cuthbert feeling?" Duncan asked.

She shook her head. "Not as well as yesterday. I am worried for him. He seems so irrational. He's asleep now. I waited to come down until he was asleep."

"Could my visit with him…"

"Not at all," she said. "His ailment grows upon him. It progresses day by day. Occasionally he has a good day, but not too often now. Apparently he has not been himself since I left to go in search of Wulfert. I suppose I should not have left him, but he said he'd be all right, that he could get along without me."

"You have great love of him?"

"You must remember, he has been a father to me. Since the time I was a babe. The two of us are family."

They reached the bottom of the stairs and now turned to the left to follow a path that led to the back of the castle park. The lawn ran down to just short of the river, fenced in by the ring of standing stones.

"You think, undoubtedly," she said, "that I am harsh with Scratch."

"It seems to me you might have been, a little. Certainly he has a right to come down off his pillar and sit upon a bench."

"But he pesters everyone," she said. "It is seldom now that we have visitors, but in the olden days there were many who came to the castle, and he always pestered them, wanting to pass the time of day with them, hanging onto them as long as possible to engage them in his silly jabber. Cuthbert felt, and I think the others did as well, that he was an embarrassment."

"I can see how that might be," said Duncan, "but he really is all right. I'm not an authority on demons, naturally, so I can't…"

"Duncan."

"Yes?"

"Let's stop all this foolish chatter. There's something that I have to tell you, and if I don't tell it to you now, I'll never have the strength to."

She had halted at the bending of the path, opposite a large clump of birch and pine. He swung about to confront her and saw that her face was drawn and white.

"There can't anything be that bad," he said, startled by the look of her.

"Yes, there can be," she told him tightly. "You remember just an hour or so ago you said that you must be leaving soon, and I said there was no hurry, that you should stay a while and rest."

"Yes, I remember that."

"I should have told you then. But I couldn't tell you. I simply couldn't say the words. I had to leave to try to find the courage."

He started to speak, but she held up a hand to stop him.

"I can't wait," she said. "There can be no further talk. I must tell you now. Duncan, it is this: you can't leave. You can never leave this castle."

He stood stupid in the path, the words not sinking in, refusing to sink in.

"But that can't be," he said. "I don't…"

"I can't say it any plainer. There's no way for you to leave. No one can help you leave. It's a part of the enchantment. There's no way to break it…"

"But you were just telling me you had visitors. And you, yourself…"

"It takes magic," she told him. "Your personal magic, not someone else's magic. It takes an arcane knowledge that one holds oneself. The visitors have had that kind of knowledge, that kind of magic. Because of that, they could go where no others could. I have some of that knowledge myself, also a special dispensation…"
