When I had gone exploring with Krip we had suited our path to the demands of his human body. But I knew I could take a much faster way up and over the heights, since my powerful claws were well fitted to climbing this rock riddled with cracks and crevices. I worked my way around until I reached a spot which I thought directly in line with those lights. There I began to climb. The rock face was dark enough so that my black fur would not show against its surface as it would have on the light dunes. As I had hoped, my claws readily found and clung to irregularities which served me well.

I made better speed at this than I had skulking about on the ground, and so managed to pull out on top of the ridge hardly winded by my efforts. From this vantage point I could see my suspicions were in part true. Three lights, giving from here a greater glow of illumination, were at the point where Foss and the others had thought they had so well hidden the cargo. Yet the effort of breaking through the plug they had left there could not be an easy one. I guessed from the vibration in the rocks, and a faint purr of sound now to be heard, that some machine had been brought in to handle that task.

So intent had I been on that distant work I was not at first aware of what lay closer. Not until I moved a little aside and edged against that beam—

Shock struck me with the power of a blow. Had I met it at a point of greater intensity I might actually have been borne back to crash into the valley.

It was pure force, delivered with such strength that one could believe such a beam should be visible. And it was mind force. Yet this was a concentration I had never experienced, even when our Old Ones merged their power for some needful action. That it had to do with the blanked minds of the humans below, I had no doubt at all. I was prepared now, wary, my defenses up, so that I could skirt the danger and not be once more entrapped. And that I must find the source, I also knew.

I did not want a second meeting with that deadly beam, yet I must somehow keep in contact in order to trace it. So I was reduced to flinching in and out on the edge, reeling away, shuffling on to touch again. Thus I came to a niche in the rocks. There was no light there, no one around; I summoned up enough mind-seek to make sure before I approached that pocket from the rear. It was very dark and whatever was in there was deeply set back in the niche.

Finally I had to pull my way to the top of the rock pile, since I had made sure that the only opening lay at the front. Crouched with my belly flat on the arch, I clawed myself forward. Then I bent my head down, hoping that the beam did not fill the whole of the opening, that I could see what lay inside.

It had seemed dark when viewed from a distance. But within the very narrow space was a faint glimmer, enough to reveal the occupant. I was looking, from a cramped, upside-down position, into a face!

The shock of that nearly loosed me from my precarious hold. I regained control, was able to concentrate on those set, grim features. The eyes of the stranger were shut, his face utterly expressionless, as if he slept. And his body was enclosed in a box which had been wedged upright so that he faced out over the valley. The main part of the box was frosted, so that only the section of cover directly over his face was clear. The face was humanoid enough, though completely hairless, without even brows or lashes.

And the skin was a pale gray.

The box which enclosed him (I believed the sleeper to be male) was equipped with a front panel which might have been transparent had not the frosted condition prevailed, for it looked like crystal. This was banded by a wide frame of metal flecked here and there with small specks of color I could not see clearly.

At the foot of the box was another piece of equipment. And while the sleeper (if sleeper he was) resembled nothing I had seen before, what sat at his feet was familiar. I had seen its like employed only a few days ago in the Lydis. It was an amplifier for communication, such as Korde had rigged when he made the off-world distress call.

Seeing it where it now was left only one inference to be drawn. The mind-blast was coming from the boxed body, to be amplified by the com device. Also, its being here could have only one purpose—that of holding Krip, the Patrolmen, and presumably the crew of the Lydis in thrall. Could I in some manner disconnect it, or abate the flow of current, they might be released.

About the boxed sleeper I could do nothing. I was not strong enough to handle the case—it had been too tightly wedged into that niche. My eyes, adjusting to the very faint light emitted from the frame, showed the rocks had been pounded in about the large box to pin it in place.

So—I might not get at the source of the mind-thrall, but the amplifier was another matter. I remembered well how cautiously Korde had adjusted the one on the Lydis, his constant warning that the slightest jar could deflect the line of force beam. But this was a task I had to push myself to. For, just as I had tired under my battle in the flitter with that which had tried to take over my mind, so now did my body send messages of distress through aching muscles, fatigue-heavy limbs.

I withdrew to the ground below and moved in cautiously from the side, creeping low and so hoping to elude the full force of the beam. Luckily it did not appear to sweep the ground.

Having made this discovery, I found it easy to wriggle closer. I could see only one possible way, and success would depend upon just how clumsy this animal body was. Backing off, I went to look for a weapon. But here the scouring winds had done their work far too well. There were no loose stones small enough to serve me. I padded along, nosing into every hole I saw, becoming more and more desperate. If I had to return to the floor of the valley to search, I would. But I still hoped.

Stubbornness rewarded me in the end, for in one of the hollows I found a rock which I worried at with my claws until it loosened, so that I could scrape it out into the open. When one has always been served by hands, it is difficult to use one's mouth. But I got the rock between my teeth and returned.

Once more I edged in as flat as I could, and with the stone between my teeth I hammered away at the top of the amplifier, until that was so battered I did not believe those who had left it could ever use it again.

I did not approach the box of the sleeper. But from that seeped a dank chill, like the worst blast of highland winter I had ever met on Yiktor. I believed that had I set paw to that frosted front, I might well have frozen a limb by that unwary touch. There was no change in the face, which could have been that of a carven statue. Yet the sleeper lived, or had once lived. Looking up at the entombed stirred a confused feeling in me.

Quickly I not only glanced away from those set features, but also backed out of the line of sight of the closed eyes. The other, added presence I had sensed in the flitter—I felt a stirring of that. And the sensation caused such alarm in me that I loped away without heeding the direction of my going.

When I had my emotions once more under control, and that hint of troubling influence was gone, I discovered I had headed not back to the ship valley but toward the lights and the purr of sound. It might be well for me to scout that scene of activity. I hoped that now that the broadcast had been stopped, those in the Lydis and flitters would be free. And it could be to their advantage if I were able to supply information upon my return.

The strangers had no guards or sentries about. Perhaps they were so certain of that which they had put to work in the heights that they felt safe. And it was easy enough to slip up to a good vantage point. . Busy at the cache they were, with flares lighting the scene, brighter even than Sekhmet's daylight. Robos, two of them, were at work on the plug we had set to seal the crevice. But the Traders had done so good a job there that the machines were not breaking it down in any hurry. They had various tools, flamers, and the like fitted into their work sockets and were attacking the fused stone with vigor.
