However, at my urging it rolled aside into the wall. I looked into a passageway. It was lighted, though by what means I could not see, save that the walls themselves appeared to give off a gray luminosity. With the blaster ready I went along.

There were doors in this corridor, each tightly closed, each bearing on its surface a series of symbols which had no meaning for me. And where in all this maze could I find Maelen? Since my sharp lesson in the hall of the sleepers, I dared not risk another call. There was no help but to look within each of the rooms I passed.

The first door opened on a small chamber holding but two sleepers. But there were also chests ranged about its walls. However, I did not wait to explore those. Another room—three sleepers—more storage containers. Room three—two sleepers again—more chests.

I was at the end of the hall and here the way branched right and left. I chose the right. The hall was still lighted and it ran straight, without any break. How many miles did this burrowing run? I wondered. It might be that Sekhmet was half honeycombed with these tunnelings. What a find! And if those chests and boxes I had seen in the smaller rooms contained such treasures as had been found on Thoth —then indeed the jacks had uncovered a mine which the Guild would not disdain to work. But why had they jeopardized their operation by sabotaging the Lydis? They could have worked here for years and never been discovered, had we not been forced down and they overplayed their hand by the attack on us. Was it a matter of being over-greedy?

The corridor I now followed began to narrow; soon it was passage for one only. There—I paused, my head up as I sniffed. Some untrackable system of ventilation had supplied all these ways. But this was something different—it was an odor I recognized. Somewhere not too far away cyro leaves had been recently burned. There were other faint scents also —food—cooked food—but the cyro overlaid most of that so strongly I could identify little else.

Cyro is mildly intoxicating, but it is also used as a counter to both body fatigue and some nervous depressions. As a Free Trader I was and am conditioned against certain drugs. By the very nature of our lives we must keep ourselves alert and with top powers of reaction. Just as we are conditioned against a planet-side interest in intoxicants of any type, gambling, women not of our kind, so we know the drugs which can spell danger by a clouding of mind, a slowing of body. So well are we armored against such that the use of any can make us violently ill.

Now I felt myself swallowing, fighting the nausea that smell induced in me. But such an odor could mean nothing less than that somewhere ahead were, or had been, others than the sleepers. After such a warning my progress was doubly cautious.

The hall ended in a blank wall, but then I saw an opening to my right, framing a brighter glow some distance ahead. And so I came out on a low-walled balcony overhanging another large chamber. This in turn was partly open to the sky. And beyond, in that daylight, I caught a glimpse of a spacer's fins, as if one side of this cavern opened on a landing field.

There was no way down from the balcony. But from this perch I had a good view of all which lay below. And there was plenty to see. To one side was heaped a pile of such chests and boxes as had been in the rooms. Many of them had shattered lids as if they had been forced. And not too far away two servo robos were fastening up a shipping crate.

Off to the right was a plasta-bubble, the kind of living quarters used by explorers as a base camp. This was sealed. But two men sat on upturned boxes outside it. One was speaking into a wrist recorder. The other held a robo control board on his knee as he watched the two busy at the crate. There was no one else in sight.

I tried to gauge the ship's size from what I could see of its fins, and decided it must be at least equal to the Lydis, perhaps larger. But there was no doubting that I witnessed a well-established and full-sized operation, and that it had been going on for some time.

The last thing I wanted to do was attract their attention. But Maelen—had she wandered in here; to be caught in some trap? Indecision held me fast. Dare I mind-call? There were no sleepers visible. But that did not mean that the jacks might not be using one as a defense or a warning.

I was still hesitating when a man came in from outside. Griss Sharvan!

Griss—I still could not accept that he was a part of this, or that he had of his own free will gone over to the enemy. I had known him far too long, and he was a Free Trader. Yet he moved freely, gave no sign of being a prisoner.

He joined the two by the bubble. The one recording got to his feet hurriedly, as did his companion. They gave the response of underlings in the presence of a leader. What—what had happened to Griss?

Suddenly his attention turned from them. His head came up, he stared straight up—at me! I fell behind the low wall edging the balcony. His actions had been those of a man alerted to danger, one who knows just where to look.

I began to crawl back to the passage which had brought me here. Only I never reached it. For what struck me then was something I had never experienced before, in spite of my many encounters with different kinds of esper power.

The command of my own body was taken from me. It was as if my mind was imprisoned in a robo which was obeying commands broadcast by a board. I got to my feet, turned around, and marched back into the sight of the three below, all of whom now watched me.

Griss raised his hand, pointed a forefinger at me. To my complete amazement I was raised from the stone under my boots, lifted above the wall, carried out and down, all as if I had antigrav on me. Nor could I struggle against that compelling force which held me captive.

That energy deposited me, still on my feet, on the floor of the cavern. I stood there, a prisoner, as the two who had been checking cargo advanced on me. Griss remained where he was, that pointing finger aimed at my head, as if his flesh and bone had become a tangler.

The man who still held the robo control reached out his other hand and snatched the blaster from my hold. Even then my hands did not change position, but remained as if I still gripped barrel and butt with them. But the other jack brought out a real tangler, spinning its web of restraint around me. When he was done, Griss's had dropped and that compulsion was gone, though now I had no chance at freedom. They had left my legs unbound, and the jack with the tangler caught my shoulder and gave me a vicious shove toward Griss.

Only it was not Griss Sharvan who stood there. Though he—it—wore Griss's body as one might wear a thermo suit. The minute those eyes met mine, I knew. Nor did that knowledge come as too great a shock, since my own experiences had taught me such shifts were possible.

However, this was no shift for the sake of knowledge, nor for the preservation of life, such as the Thassa practiced. The personality which had taken over Griss was alien to our kind as the Thassa could never be. I had a swift mental picture of a terrifying creature—a thing with a reasonably humanoid body but a head evilly reptilian, a mixture which repelled.

Only for an instant did I hold that mental image; then it was gone. But with its disappearance there was also a flash of incredulous surprise, not on my part, but from the alien. As if he—it—was astounded that I had been able to pick up that image at all, as its true nature was so well concealed it never revealed itself.

"Greeting, Krip." Griss's voice. But I knew well that those slow, toneless words carried another's thoughts. I did not attempt any mental scanning, being warned by instinct that such would be the most dangerous thing I could do. "How many are with you?"
