Then one of their men on Thoth could have picked up the news of our cargo. And they might have prepared to gather that in as a bonus. The Throne of Qur would be worth any effort. I could not help but believe that was the answer.

But what other devices could they have? That which sabotaged the Lydis we still do not understand. And the esper was something entirely new. Nor were the Free Traders backward in hearing about such things.

"Look out!"

I was startled out of my thoughts by Harkon's cry. We could still see the scene of the cargo cache. The robos had started to bring out what we had stored there. But it was not that action which the Patrol pilot had noted.

One of the guards had turned about, was pointing his blaster directly at our screen. A moment later that went black.

"Took out the snooper," Harkon commented.

"Now they know—first, that their esper is no longer controlling us; second, that we have learned of their activities in turn," Lidj said. "Do we now expect an attack in force?"

"What arms do you carry?" Harkon asked.

"No more than are allowed. We can break our seal on the ordnance compartment and get the rest of the blasters. That's the extent of it. A Trader depends on evasive action in space. And the Lydis does not set down on worlds where the weapons are much more sophisticated than on Thoth. We haven't broken that seal in years."

"And we don't know what they have—could be anything," Harkon commented. "I wonder who took out that amplifier. Might that man of yours be operating on his own—the one you did not see?"

But I was as certain as if I had witnessed the act. "Maelen did that."

"An animal—even a telepathic one—" Harkon began.

I eyed him coldly. "Maelen is not an animal. She is a Thassa, a Moon Singer of Yiktor." The odds were that he had not the slightest idea of what that meant, so I enlarged on that statement. "She is an alien, wearing animal form only for a time. It is a custom among her people." I was determined not to go farther into that. "She would be perfectly capable of tracing the esper interference and knocking out the amplifier."

But where was she now? Had she gone on to the cache to see what was happening there? I did not know how the jack guard had picked the snooper off so accurately. They were programmed to evade attack. He could have been just as quick to dispose of Maelen, had he_sighted her. They had probably been planeted on Sekhmet long enough to know most of the native wildlife, so they would have recognized her even in animal form as something from off-world, and been suspicious. I could imagine plainly the whole sequence of such a discovery.

If only I dared mind-search! But even though the amplifier was not of use, I knew I could once more bring upon myself that force I had experienced earlier. Until the stass frozen man—or thing—was rendered harmless (if he could be) I had no hope of tracking Maelen except by sight alone. And in the dark of night that was impossible.

"We can just sit it out," Korde was saying when I again paid attention. "Your ship"—he nodded to Harkon—"will be back soon with Foss. We have power enough to warn them once they come into braking orbit."

But Lidj was shaking his head. "Not good enough.

The jacks must have been watching us all along, even if we could not detect them—they certainly possess a protective field which blanks out even esper when they want, or Maelen would have picked them up earlier. So they know about us and that we are waiting for help. They could move fast now—pack up and be off-world before we get reinforcements. After all, their base may be half this continent away, hidden anywhere. We've got to keep on their tails if we can. But it won't do any good to try another snooper. They will be watching for that now."

"We haven't one anyway," Harkon commented dryly. "For the rest, I would say you are right. There is also this—if we stay in or around your ship, they may be able to pin us down, blank out an com warning, hold us just as tightly as they did before. I say, leave the ship with a guard and a locked-up boarding ramp. The rest of us will take to the country. It is rough enough to hide an army. We'll work our way northeast, starting at the cache, and see if we can at least locate the general direction of their base. They won't be able to transport all they are pulling out of there without making a number of trips. Also—that esper is still up there. If we find him before they come to see what is wrong, we may just be able to shut him off, or do whatever needs to be done to hinder them in using him again. And what about this Maelen of yours—can you contact her, find out where she is?" He spoke directly to me.

"Not as long as that esper is broadcasting. You saw what happened when I tried that before. But I think she is near that cache. It may be that if I get close enough she can perhaps pick me up, though I can't be sure. She is far more powerful than I am."

"Good. That makes you our first choice for the scouting force." He certainly did not wait for volunteers. Not that I would not have been the first of those. But a Free Trader does not take kindly to any assumption of authority except from his own kind. And it was very apparent that Harkon considered himself without question to be the leader of any sortie we planned.

Lidj might have challenged him, but he did not. He went instead to break the seal on the arms locker. We took out the blasters, inserted fresh charges, slung on ammunition belts. E rations were in packets. And we had our thermo suits as protection against the chill.

In the end Korde and Aljec Lalfarns, a tubeman, stayed with the ship. Harkon's gunners from the fritter removed the charges from those crafts' defense to render them harmless and made ready to join us. It was still dark, though dawn could not now be too far away. We had a short rest and ate our last full ship's meal before we left.

It was decided we would try the more arduous climb up over the cliff, so we could find the esper and take action to insure he would not trouble us again. And climb we did, the blasters on their slings over our shoulders, weighing us back, making the climb more difficult, though the face of the stone was already rough enough. We had had to put aside our mittens in order to find handholds, and the chill of the rock bit deep, so that we must press on as quickly as we could before any numbing of our fingers could bring about disaster. I thought of Maelen's sharp-pointed claws and knew that this road must have been a fairly easy one for her. But her passing had left no traces.

We reached the top of the cliff, spread out in a single thin line as Harkon ordered. From this height we could see the lights at the location of the cache. The workers there made no effort to hide their presence. And, having been alerted by the snooper, they could already be preparing a warm welcome.

Our advance had been very short when my wrist com buzzed. "To the right," clicked the signal which brought me in that direction, picking my way more by feel than sight.

Thus we gathered at the niche we had seen from the snooper. The smashed amplifier had not been moved. It was apparent that those who had installed it there either had not arrived to check on it, or had abandoned it. I stepped closer, flinched. For the first time in my life I experienced mind-send not only in my brain, but as an invisible but potent force against my body.

"Don't go directly in front of it!" I said sharply.

At my warning Harkon edged in from one side, I from the other. There was no sign of life on that face. It was humanoid, yet it had an alien cast. I might have been looking at a dead man, in fact I would have said so, had I not felt that strong current of send. The Patrolman stepped back, yielding his place to Lukas. Now the medic put out his unmittened hand and moved his fingers, held an inch or so away from the surface of that case, as if he were smoothing it up and down.
