The ring pulled me on, and it seemed to me that its tug was stronger, as if it grew impatient, redoubling its demand on me. I found myself running, or trying to run, through the sand, though it was hard to keep my feet, my left hand, holding the ring so tightly my fingers cramped, straight out, across my body, pointing to the platform.

When I reached the bridge I was caught in a dilemma. To let go of the ring, to holster the laser, both actions might mean disaster. Yet I was not sure I could shift the bridge without using both hands and all my strength. The wood lengths from which it had been made were bleached white and might be lighter than they looked - but- Carefully, fighting until I was sweating as if I had been in another brawl with Hory, I forced the ring back to my chest, unsealed a slip of the coverall, and clapped the band inside. Within my clothing it pushed out the fabric, but that was tough and would hold.

The laser went into my belt, and I hurried to deal with the bridge. It was unwieldy, but my hopes that it was light were realized. I got it up and swung it around, so that the other end dropped on the top of the wall. And I had no sooner done that than the seal on the breast of my coverall burst open. Not the fabric, but the fastener had yielded to the struggling of the ring.

My grab missed the band. With the stone flashing in triumph, it flew out toward the platform. Now I must follow.

I made that trip on my hands and knees, Eet running as a dark streak ahead. And I felt particularly vulnerable as I climbed. For the span swung alarmingly under my weight and I thought that at any moment it would slide from its hold on the upper wall and hurl me into the water.

There was also the possibility that the sniffers might return. And I had no wish to conduct a running battle up or down this very precarious pa.s.sage. But at last I was able to put out a hand and rest it on solid and unyielding stone, pull myself to the dubious safety of the wall, and then jump to the platform.

The smoke from the nearest head trailed about me, and I sneezed at its odor. Then I thought, for a second or two, that there was a fifth fire lit in the center of the platform, though this did not smoke. Eet was warily circling that blaze - which was no fire after all, but the stone, in such furious display of energy as I had never seen.

"Keep off!" Eet's warning stopped me. "It is too hot to handle. It is trying to reach what calls it so strongly. And it will either destroy itself now, or reach that which it seeks. But it is beyond our control."

I knelt to see the better. Beyond our control? It had always been that. We had set it to our service in the ship, but how easily it had broken free. And all other times we - or I - had obeyed it and not it me.

Eet was right. The warmth that came from it was now a seething furnace heat. There was a raw radiance which hurt my eyes, a thrust of heat that drove me back and back, until I crouched against the wall beneath one of the smoking heads.

The mutant was probably right in believing that this unendurable burst of energy fought to destroy the stone, burn it to one of those cinders. But if it sought death, it was going in a blaze of glory.

I had to shield not only my eyes but my face against the fury. Eet was not with me. I hoped he was safe on the other side of that inferno.

"Just so," he let me know. "It is still trying to cut through."

I did not try to witness the struggle. The bursting light would have blinded me. Even though I shut my eyes, held my hands tightly across them, and turned my face to the wall, I could feel the effects of the holocaust. Could I bear it much longer? If the heat increased I might be seriously burned, or forced into the lake. Between one fate and the other there was little choice. Then - that lashing heat was gone! The stone had died- Pushing around, I got to my feet. I did not take my hands from my face and open my eyes until I stood upright. Then I looked away, dreading to face what must lie in front of me.

When I did, I fully expected to see a charred cinder. But what was there was an opening in the platform, a perfect square, as if some door had been burned away. And the light from below was not exactly faded, but was pulsating in a less strident and eye-destroying way.

Eet had already reached the hole. I saw his head shoot out and down as he stretched his neck to its greatest extent to view what lay there. But I went more cautiously, testing each block I stepped upon. That hole bore a likeness to a trap door and I had no wish to be caught in such.

The surface seemed solid enough, and with a couple of hesitant strides I joined my companion to look into the interior. The glowing stone lay on a coffer such as the one we had seen in the derelict ship. But the stones in this were very much alive, more so even than those in the cache of the ruins. And their light, coming through a slit, gave us an excellent view of the vault.

It would seem that the platform was only the outer sh.e.l.l of a room, perhaps a storeroom like that of the ruins. There were many boxes in orderly piles along its walls, and none of them had been affected by time. All were tightly sealed, showing not even hair-thin marks of an opening.

Only after I had studied them for a long moment did their general size and shape make me uneasy. There was something about them - long, narrow, not too deep. What was it-?

"Can you not see?" asked Eet. "These did not give their dead to the fire; they hid them away in boxes, as if they could lock them from the earth and the changes of time!" His contempt was cold.

"But those stones - if this is a tomb, why leave the stones here?"

"Do not many races bury treasures with their dead, that those no longer with them may carry into the Final Dark what they esteemed most in the days of their strength?"

"Primitive peoples, yes," I conceded. But that a race which had achieved s.p.a.ce flight would do so - no. And now I noted something else. While many of those boxes did bear too close a resemblence to coffins to dismiss Eet's explanation as fantasy, there were others of different dimensions.

Eet interrupted my thoughts. "Look about you!" His head shot up and turned from side to side, the nose pointing at those rows of heads. "Different species, perhaps different shapes for bodies. This was a composite tomb, made to hold more than one people-"

"Yet all following a single burial ceremony?" I countered. For even among the same species there are different modes of paying honor and bidding farewell to the dead. And to find one vault holding so many burials, seemingly united- "It might be so," Eet answered. "Let us a.s.sume that a composite garrison, even a single ship's company, were marooned here. That there was no chance for their eventual return home. Yet, they would hope that in the future there might come those to seek out their final resting place."

My mind took an imaginative leap. "And the stones were then left as payment for their return to their proper worlds, or for the type of funeral they desired?"

"Just so. Those would do as burial fees."

How long had they waited? Did the worlds which had given them birth still exist? Or did these planets now lie barren under dying suns half the galaxy away? Why had the builders of this place remained here? Had their empire broken apart in some vast and sudden war? Had the relief ships never come? Had the ship fallen at the ruins been their last hope, destroyed before their eyes in some mechanical or natural catastrophe? And the derelict we had found drifting - had that been a relief ship they had awaited? When it did not arrive had they surrendered to the fact of no escape and built this vault to tell their story to the future?

I glanced from wall to wall of that tomb. There was no message left there for our reading. Then I looked once more at the heads of the parapet. These, seen close up, were eroded to some extent, but they had not been as badly aged as the ruins by the cliff. Were they the actual portraits of those resting below, or did they only represent types of races?

Six were definitely nonhuman. Of those, one, I believed, was insectile, at least two vaguely reptilian, one batrachian. The rest were humanoid enough to pa.s.s as kin to my own species. Two were as manlike as the s.p.a.ce rovers of my own day. There were twelve of them - but what had brought such a mixture to this planet?

I turned to Eet. "This must be the source of the stones - and these came to mine them."

"Leaving the galleries picked so clean? That ring did not lead to them. I do not believe that could be true. This may have been a way station for such a shipment. Or it may have had a purpose we cannot conceive of now. But - the fact remains that we do have here a cache of live stones. Enough, as that Patrolman would point out, probably to disrupt the economy of any government. The man or men who take that box and are able to hold it will rule s.p.a.ce - for as long as they can keep the stones."

I came back to the vault opening. "The light- it is beginning to die. Perhaps the stones are also-" It was decidedly less light in the crypt.

Eet crossed the platform in a couple of his bounds, leaping now to the parapet. Only for a second did he so face the ship, his whole stance suggesting he was alert to what I could neither see nor hear. Then he was back at the same speed.

"Down!" He dashed against me, his impetus striking me almost waist-high. "Down!"

I did drop, my feet going over the edge of the opening. Then I swung by my hands and landed with a jar on the floor, sc.r.a.ping against the side of the box which held the stones. Though the light they emitted was now no more than a small and flickering fire, it was enough to show me safe footing.

I glanced up just in time to see a spear of light flash across the opening, hardly above the level of the parapet. Laser - but not a hand one! That was from the barrel of a cutter, and it must have been fired from the ship!

Eet climbed a pile of those boxes. He was crouched now well away from the hole, yet near the wall facing the ship, his head laid to the stone blocks as if through them he could still hear something.

I put my hand on the ring. There was warmth in it, and a gleam to the stone, but as far as I could see, it no longer threatened any would-be wearer. And, to my surprise, it did not adhere to the box, but came away easily. For safekeeping I put it into the front of my coverall, making sure the seam was tightly sealed.

Again I looked to Eet. The glow was further reduced, but not entirely gone. I could see him well enough.

"Hory?" I asked.

"Just so. It would seem he had resources we did not know about. Somehow he loosed himself. He has now tried to kill us and failed, so he will search for another and more effective form of attack."

"Go off world-bring in the Patrol?"

"Not yet. We have hurt his pride sorely by what we have done to him. There was more to his being here, I believe, than we - or I - first read in his mind. He may have had an inner shield. Also, he believes if we are left here we shall of necessity join forces with the Guild and perhaps be beyond reach before he can return. No, he wants the ring - and our deaths - before he goes."

"Well, we may not be dead - but how will we get out of here?" To try to climb again to the platform would expose us to Hory's beam. He need only wait; time was now on his side.

"Not altogether," Eet informed me. "If the Guild left men here, and we can safely conclude that they did, they will have monitored our planeting. And they will send to see who landed. Remember, they picked up Hory the first time. Almost too easily. Now I wonder why."

I brushed aside Eet's speculations about the past. "We may be half a continent away from their camp."

"But they must have some form of small aircraft. It would be necessary for their explorations. Yes, they will come - and I do not think we are as far from their base as you suggest. The ruins were once part of a settlement of some size. This tomb would not be located too distant from that."

"Always supposing it is a tomb. So we have to sit here and wait for the Guild to come after Hory. But how will we be any better off then?"

"We shall not, if we do so wait," Eet answered calmly.

"Then how do we get out - just by wishing?" I asked. "If we top that hole, he burns me - though you might be able to make it"

Eet still held his listening position against the wall. "Just so. An interesting problem, is it not?"

"Interesting!" I curbed my temper. I could think of several things to call the present situation, all of them more forceful than "interesting."

SEVENTEEN.

My hand kept returning to the ring beneath my coverall. It had led us on a wild chase, probably to our deaths - where we would lie in company. I glanced around the vault. The light was low, and shadows crept toward us from the rows of ominous boxes. Behind those was only the heavy masonry of the walls. Even if we were able to cut through on the opposite side from the ship so that Hory might not sight our going, we would still have the water to cross.

The ring. It had saved me and Eet before, though perhaps that was only incidental to its seeking for its kind. Could it do anything to get us out of here? Hory wanted it - wanted it badly I glanced at Eet, who was now a barely discernible blot against the wall.

"Could you reach Hory's mind from this distance?"

"If there was a reason - I think so. His has - at least on the surface - a relatively simple pattern - like yours."

"How much influence could you bring to bear on him under contact?"

"Very little. Such a tie needs cooperation to be successful. The Patrolman does not trust me, nor would he open his mind to me now. It would be necessary to break down active resistance. I coud not hold him in any thrall."

"But - you could me?" I did not know just what I fished for. I was one feeling his way through the dark by touch alone. If I chose rightly it meant life; if I failed - well - we might not be worse off than at present.

"If you surrendered your full will. But that is not in you. There is a stubborn core in your species which would resist any take-over. Whether you wished to cooperate or not, I would have a struggle on my hands."

"But Hory does not know that. All he knows is that you communicate mentally. He knows, though he will not admit it, that you are not an animal. Suppose he were led to believe that you have been controlling me all along, that I am only hands and feet to serve you. Suppose I acted that part now, got out there saying you were dead, I was free and wanted nothing more than to get back with him - bringing the ring?"

"And just how are you going to make that clear to him?" Eet inquired. He left the wall, flowed over the boxes to hunch before me, his eyes level with mine. "If you emerge on the platform he will burn you instantly."

"Can you die spectacularly in a way he can see?" I countered.

There was amus.e.m.e.nt rather than any direct answer. "Clutching my throat and flopping about?" he asked after a moment. "But with a laser you cannot perform so. I would be scorched fur and a dead body instantly. However, always supposing we could convince Hory I had made my exit permanently - what then?"

"I would emerge, dazed, cowed, ready to be taken prisoner-"

"While I would later come to your rescue? Do you remember that we played somewhat similar roles before? No, I do not believe Hory is so gullible. Do not underestimate him. He may be more than he seems."

"What do you mean?"

"I believe he has a mind shield - that I have read only surface thoughts - perhaps what he was programed to reveal. Did not you yourself once say 'Do not underrate your opponents'? However, your suggestion has some points worth considering. Suppose you were the one to meet his laser beam?"

"But - he hates you. Would be treat with you?"

"Just so - a question. However, there is an implanted feeling in your race that size and superior muscularity count much. Hory hates me as a freak, a thing which belies his superiority. Therefore, he must deal with me - for his own emotional satisfaction - not by a flash of fire, but rather by delivering me to his superiors in triumph. So far we have bested him and that rankles. I wish we knew more." Eet hesitated. "He is a puzzle. And he is also intelligent enough to know that time is his enemy. Do you think he has not already figured out a Guild detachment may be on its way here?

"But they could not shake him out of his ship. Only - he needs the ring as a booster to take off. He wants the ring, and he would like me - you are merely incidental."

"Thank you!" But Eet's dissection of the problem was not irritating - it was true. "So I die-"

"As conspicuously as possible. I will then endeavor to take over the n.o.ble mind of Hory, promising him the sun, any vagrant moon, and, of course, the stars, all via the help of the ring. I think he will use a stun beam on me-"

"But-"

"Oh, I do not think that weapon will be as effective as he thinks it is. I shall be transported to the ship, doubtless installed in a cage, and Hory will see his way clear to departing."

"Leaving me here? How-"

Again amus.e.m.e.nt from Eet. "I said I could not control Hory without his a.s.sistance. But there is one time when that a.s.sistance, unconsciously, may be mine for a short period. When he thinks I am totally in his power, he will then, by our hope, relax his guard. I do not need to advise you that period will be short. I am his shocked and docile prisoner, you are dead. He has full control-"

"And if the stunner really works on you?"

"Do you want to await death here?" Eet countered. "What one can say this or that sore stroke will not fall on his shoulders, aimed by the strong arm of fortune? Do you wish to sit here waiting for the Guild, or perhaps for Hory to switch on whatever heavy armament his ship affords and burn us to the bare rocks, setting even those to bubbling around our roasted ears? What I have learned of your minds suggests I have a good chance for what I propose to do. Esper powers are not used much and to mechanical devices such as cages there are always keys."

Perhaps my partnership with Eet had made me particularly susceptible to his self-confidence, or perhaps I merely wanted to believe that his plan could work because I could not turn up a better. But I made tacit agreement when I asked: "And how do I die by laser beam without being crisped in the process? That is a weapon one does not dodge, or survive. And Hory will not be aiming over my head, or any place except where it will do him the most good and me the least!"

It was now twilight in the vault and I could see Eet but not too clearly. If he had a plausible answer I was willing to agree that in this partnership he was the senior.

"I can give you five, perhaps ten heartbeats-" he answered slowly.

"To do what? Act as if I were going to jump in the lake? And how-"

"I can expend a little power over Hory, confusing his sight. He will aim at what he thinks is his target. But that will not be you."

"Are you sure?" My skin crawled. Death by fire is something no one of my kind faces with equanimity.

"I am sure."

"What if he comes to view the remains?"

"I can again confuse his sight - for a short period." After a long moment's pause he spoke more briskly: "Now - we make sure of a future bargaining point-"

"Bargaining point?" My imagination was still occupied with several unpleasant possible future happenings.

"The cache of stones here. I do not think that without the ring they will be visible."

"The ring." I took it out. "You will take the ring, and leave the stones here as bait to draw him back?"

Eet appeared to consider that. "If he had more time perhaps. But I think not now. Give me the ring. These - we do not want them in sight, if and when he comes to pick me up."

It was my muscle which dragged the box from below the opening and concealed it back behind one of the rows of coffins.

"Now!" Eet sat on a box. "He will not fire until you are out in the open, making a dash for the parapet. The laser may beam close enough so that you will feel its heat. The rest is up to you."

My good sense belabored me as I climbed up, reached out to grasp the edges of the opening. If- if- and if again- Eet popped out, running, heading for the parapet. I had only an instant and then I fell, a searing, biting pain along my side - a pain so intense that I was aware of nothing else for a second. I could smell my clothes smoldering. Then Eet was back with me, pulling at my coverall as if to urge me up and on, though in reality putting out those lickings of fire.
