"Well," I said, "if those canines were removed, and you were shaved all over and put into a suit of clothes, you might be able to pass for an unusually ugly specimen of humanity—no offense intended. You could make a fortune as a wrestler or boxer. I could introduce you to an honest manager, relatively honest, anyway. But you wouldn't be happy there, and sooner or later some zoologist would look closely at you, and the game would be up. Besides, city life would sicken you, you couldn't stand the gas fumes, the factory stinks, the noise, the crowds, but ... "

I shouldn't have told him all that. I needed him, and it wouldn't help, any to discourage him with the truth. If he had been a human being, I would have lied to him. But he was one of The

Folk, and even though I have loved only two members of that genus, tolerated some others, and hated most, I could not lie to this simple trusting soul. That is, if he was as open and simple as he seemed to be. I had to remind myself that he could be a cunning agent for the Nine.

"There was a time when you could have lived with me on my plantation in Kenya," I said. "But I lost that, and I can't ever return to Kenya, not unless I'm disguised. But I'll think of something. The important thing is to get out of here. As soon as possible."

"If anyone could do it, you could," Clara said. "Or maybe Caliban. But nobody can. You'd have to be a bird to get out of here."

At dusk our supper was lowered. We went into a stone hut to eat and talk. There was no furniture there except for a pail to throw our garbage into. Our only bedding was a pile of old blankets, but these sufficed to keep us warm, with the help of each other's body heat. Back of the hut was a latrine ditch. As soon as night fell, and it fell early here, while the sky, three thousand feet above, was still a dark blue, we left the hut. The south end was lit by powerful beams, and a searchlight' probed the valley. But we walked to the far north end, ignoring the light when it followed us. I plunged into the pool, sixty feet long and thirty wide, at the base of the northern wall. The water was icy, but I waded waist-deep until I got near to the wall, where I had to dive down. There were several openings in the rock through which water bubbled. But all were too small for me to get into.

After thoroughly exploring the bottom, I got out. I ran all the way to the other end to dry myself and warm up. Dick and Clara followed me at a brisk walk.

I was visible to the men above in the lights glaring down. They could see what I was doing, and if they wished to stop me, they had the means. But I think they were just laughing at me. I went into the tiny pool there and dived down to the bottom. This was about thirty feet deep, and the water flowed through an opening about six feet across. But a thick metal screen had been affixed to the rock with many metal spikes. I tugged at the screen about a dozen times, coming up for air each time. By the time I gave up, I was half-frozen, and it took me a long time to stop shivering. Somebody at the top of the cliff hooted at me for my efforts.

However, I did not feel that I had been foolish or wasted my time. That they had felt it necessary to screen the hole indicated that the hole might be an escape route.

After I had gotten warm under the blankets between Clara and Dick, I crawled out. Dick wanted to sleep; despite being raised by humans, he was one of The Folk in being unable to look far into the future. I told him he might lose more sleep before we got out of this, and if we didn't, he'd have as long to sleep as anybody ever wished for. Grumbling, he followed me out. We sneaked past the probing searchlight to the detritus of flint I had seen at the northeast corner. Apparently, it had fallen there when a projection was blown off about fifty feet up. Since there was no light, I could not work the flint. But when dawn came, I went to the door of the hut with a blanket over my shoulders. By the dim light there, I hammered and chipped away until I had several handaxes, long stabbing knives, scrapers, and choppers. I had learned the techniques from a French anthropologist who was once a guest at Grandrith Manor.

"What do you plan to do with your Early Paleolithic weapons, my cave man?" Clara said.

"I don't know yet," I said. That was true, but if I had a plan, I would not have told her until just before I initiated it.

"Well, at least you're keeping out of mischief."

The day passed just like it had before, except that Dick and I dived down to the bottom of the outlet pool and strove to pull the screen loose. When we came up for air, we could look up and see the faces of our guards there. They did not fire down to drive us away. It may be they felt there was no slightest chance of our loosening the screen. And if we wanted to exercise and to provide them with some slight amusement in a deadly dull job, so be it.

We gave up after a dozen dives. If our combined strength could not pull a corner of the screen loose with our bare hands, then tools were needed. I spent the rest of the day traveling around the base of the canyon and examining the walls. The northeast corner formed an almost square junction. By putting my back against one wall and pushing with my feet against the other, at a difficult angle, I might be able to inch my way up for the first hundred feet. After that the walls leaned slightly outward until, near the top, they were at an angle of about eighty-two degrees from the horizontal. The corner still maintained its squareness, but I would have to exert a tremendous pressure to keep from falling. I was not sure at all that I could do it. As far as I could tell, there were no guards on that side.

Two hours before dusk, two men holding rapid-fire rifles were lowered. They stood guard while their officer, a Lal Singh, rode down. Then two other riflemen rode down. Then a man with scuba gear.

We three prisoners were allowed to stand within forty feet and watch them. The scubamen came up with a satisfactory report. Then our huts were examined. They did not find the flint weapons because I had hidden them beneath the surface of the north pool. The scubamen did not look into that pool. Evidently they knew that I could do nothing there.

After making searches at random in other parts of the canyon, they left. Just before he was hauled away, I asked Singh what had happened to Murtagh. He did not reply. I surmised that Murtagh had been sent to Germany after Caliban. Probably nothing would be done with me until he was killed or captured. But I could not bank on that. If Clio was caught and brought here, the Nine might think there were enough victims for a Roman holiday.

As soon as it was dark, I sneaked out and cut down some of the hardwood bushes. I trimmed them off and sharpened their points. I still did not know what to do with them, but if a situation arose where they would be handy, they would be waiting and ready. And they could be used as pitons, if I found a big enough crack.

I wanted to tell Clara and Dick what I planned. If their stories were true, then they should be with me. I did not think that Clara, strong though she was, could manage that climb. Dick was powerful enough, stronger than me, but he was also much heavier. And I just could not chance that they were spies. That the men had come down to search the area did not mean that either of my fellow prisoners had informed on me, of course. Almost everything I had done had been visible. And if my flint tools had been discovered, I might have suspected that I had been betrayed. No, they would say nothing about the flint.

An hour after nightfall, I slipped out from the blankets. Clara and Dick both stirred, and Dick said something, in Swahili, in his sleep. I stood there for a while, made sure they were deeply asleep, or else pretending to be, and left with my sticks. I waited a while by a bush to see if anybody would follow me. No one did. The beams probed around at random. I avoided them, went to the north pool, and recovered my flint weapons.
