"Monat asked Spruce how long this process would take. A thousand years? Two? A million?

"Spruce became angry, and he shouted, 'You will stay here as long as it takes you to be rehabilitated! Then...'

"He paused, glaring at us as if he hated us, and he said, 'Con­tinued contact with you makes even the toughest of us take on your characteristics. We then have to go through a rehabilitation process ourselves. Already, I feel unclean...'

"One of the councillors, wishing to press him, urged that he be put over the fire until he would talk freely.

"Spruce cried, 'No, you won't! I should have done this long ago! Who knows what...'"

Burton paused dramatically.

"Then Spruce fell dead!"

There were gasps, and someone said, "Mein Gott!"

"Yes, but that isn't the end of the story. Spruce's body was taken away for dissection. It seemed too coincidental that he should have had a heart attack. Not only was it too convenient for him, it was unheard of.

"While he was being dissected, we discussed what happened. Some thought that he was lying to us. Or, at least, only giving us half-truths. We did agree on one thing. That was that there were people in this Valley who were agents of the Ethicals or perhaps the Ethicals themselves. These did not bear the mark on their foreheads.

"But it seemed likely that we would not be able to distinguish them anymore by using Kazz's peculiar visual powers. Spruce would be resurrected wherever their headquarters was. He would report to the others that we now knew about the symbols. And of course they would put the mark on their agents.

"This would take time, and in the meantime Kazz might detect others. But this has not happened. Neither he nor Besst has seen anybody unmarked. Again, of course, this does not mean too much. They have to get a close look under certain conditions to see the mark.

' "Three hours later, the surgeon reported to us. There was nothing remarkable about Spruce. Nothing to distinguish him from, other members of Homo sapiens."

Once more, Burton paused.

"Except for one small item! This was a very tiny black sphere! The doctor had found it on the surface of Spruce's forebrain. It was attached to the cerebral nerves by extremely thin wires. This led us to conclude that Spruce had literally thought, or wished, himself to die.

"Somehow, the sphere interacted with his mental processes in such a manner that he could think himself dead. Perhaps he thought of a certain code sequence, and this released a poison into his system. The doctor could find no evidence of this, but then he lacked the necessary chemical means to make an accurate analy­sis.

"In any event, Spruce's body showed no damage. Something had stopped his heart, but the doctor did not know what that was.''

A woman said, "Then there could be such people among us? Now, here, in this group?"

Burton nodded, and everybody started talking at once. After fifteen minutes of this babel, he stood up and indicated to his crew that it was time to go to bed. On the way to the cutter, Kazz drew him aside.

"Burton-naq, when you mentioned you and Monat were hyp­notists... well, that made me think about something. I've never thought about it before . .. maybe there's nothing funny about it... only..."

"Well?"

"It's nothing, I'm sure. Only it was funny. You see, I told Spruce I could see he didn't have no sign on his head. He left a few minutes later, but I could smell the fear in his sweat. There were others there, all eating breakfast, Targoff, Doctor Steinborg, Monat, Pete, and a number of others. Targoff said we should convene the council, though this was some time after Spruce had taken off. Monat and Pete agreed. But they said they wanted to question me a little more. You know, what the marks looked like. Were they all alike or did they differ?"

"I said they differed. A lot of them were... what you say?... similar, yes, that's it. But each one . .. what the hell, you know what they look like, I've drawn pictures of them for you."

Burton said, "Aside from some looking something like Chinese ideograms, they resemble nothing I've ever seen. My guess is that they're symbols of a numbering system."

"Yeah, I know what you said. The thing is, Monat and Frigate took me aside before we went to your place to tell you what'd happened. In fact, we went to Monat's hut."

Kazz paused. Impatiently Burton said, "Well?"

"I'm trying to remember. But I can't. I went into the hut, and that's all!"

"What do you mean, that's all?"

"Burton-naq, I mean that's all. I don't remember a thing about going into that hut. I remember starting through the door. The next I remember is walking with Monat, Pete, and the other councillors to your hut!"

Burton felt a slight shock, yet he had no idea what had caused it.

"You mean that you don't remember anything from the time you entered until the time you walked out?"

"I mean that I don't remember walking out. All of a sudden, there I was, a hundred paces from Monat's house and walking along, talking to Monat."

Burton frowned. Alice and Besst were standing on the dock, looking back as if wondering why they had dropped behind.

"This is most peculiar, Kazz. Why haven't you told me about this before? After all, it's been many years since it happened. Didn't you think about this before?"

"No, I didn't. Ain't that funny? Not one frigging thought. I still wouldn't remember even entering the hut if Loghu hadn't said something about it the other day. She saw me go in, but she wasn't with the group that day and so didn't know what was going on until later.

"What happened was that she was standing in the doorway of her and Frigate's hut. Frigate, Monat, and me was going to go into Frigate's hut. When they found she was there, they went to Monat's. It was just by chance that she mentioned this yesterday. We was talking about when we was grail slaves, and this brought up Spruce. That's when she asked me what Monat, Pete, and me was talking about. She said she wondered sometimes why they wanted to talk to me in private.

"She just never brought it up before because it didn't seem important. It still wasn't, but she was curious, and since the subject was brought up, she remembered to ask me. You know how curious women are."

"Women have the curiosity of cats," Burton said, and he chuc­kled. "Whereas men are as curious as monkeys." "What? What does that mean?"

"I don't know, but it sounds deep. I'll think up an explanation later. So, it was Loghu's remarks that made you remember the events preceding and following your entry into Monat's place?" "Not right away, Burton-naq. I got to puzzling about what she said. I really strained my brain. I could hear the tissues ripping. Finally, I could remember, in a dim way, how we meant to go into Pete's hut. Then I could remember Loghu being there and Monat saying they'd use his hut. And after a while... I could faintly recollect going into there.

"While you was talking didn't you notice me sitting there by the fire, frowning away like there was a thunderstorm on my brow?"

"I just thought you'd taken too much to eat and drink, as usual.''

"That, too. But it wasn't no farts storming around inside me. It was gas on the brain."

"Since you've recalled this, you haven't said anything to Monat or Frigate about it?"

"No."

"Don't, then."

Kazz had a low forehead, but he was not unintelligent.

"You think there's something phony about those two?"

Burton said, "I don't know. I'd hate to think so. After all these years . .. and they are good friends. At least..."

"It don't seem possible," Kazz said. He sounded as if his heart were about to break.

"What doesn't?"

"I don't know what. But it has to be something bad."
