I knew the Kur must be cunning, if not brilliant. It could be no accident that this Kur and not another had received this dreadful assignment, to protect the device of a planet’s destruction until its detonation.

But also it would be under stress. And in the storm it could not see clearly beyond the portal. It would assume that I would not relinquish the shield of the ring’s invisibility. A diversion would be ineffective, for what could draw the Kur from his position? If the blood of the slaughtered humans about had not been sufficient to override his obedience to the dark imperative of the steel worlds, I did not think anything I might contrive could lure him forth. He had resisted blood; the will of this Kur, restraining its instincts of feasting and carnival, must be mighty indeed. He would assume, perhaps, I might attempt to draw fire with a decoy, thus slipping into the ship. The only likely object to use in such a plan would be the body of one of the humans about, victims of the Kur with whom I had shared the march in the desert. I made no attempt to conceal my wounds. I let it be clear that I was outside the portal, that I had ascended the side of the ship, that with me, dragged, was an inert weight, presumably a body.

A likely plan, it seemed to me, would be to thrust the inert body into the portal, and draw the fire of the Kur within. Perhaps then, in the sudden moment of confusion, one might slip within, behind it, invisible.

It would be an elementary decoy strategy.

This was a likely plan. I did not adopt it. The Kur waited within. I did not think I played Kaissa with a fool.

But I would use a decoy strategy. Only I, myself, would be the decoy. Behind the decoy there would be nothing. One thing the Kur would not expect would be that I would surrender the shield of invisibility; one thing he would not expect would be that it would be I, myself, who would present myself to his weapon. I clung to the side of the portal. I propped the body beside me, holding it that it not be swept from the side of the ship. I counted slowly, five thousand Ihn, that the reflexes of the Kur within be drawn to a hair-trigger alertness, that the whole nervous might of the beast might be balanced on a razor’s edge of response, that every instinct and fiber in his body would scream to press the trigger at what first might move. But I counted, too, on its intelligence, its control, that it would not fire on what first might move, particularly if it were visible.

The wind howled and the sand swirled about the ship. I pressed the circular switch on the ring tied about my neck. I again saw in the normal range of the spectrum. I now realized I saw in the light of the moons; I broke out in a sweat; it was night. Limply, as though thrust from behind I pushed myself, awkwardly, sagging, into the opening, and fell forward. Scarcely had I fallen into the lock than I heard, loud, over me, the concussions of the weapon, firing five times; almost simultaneously the Kur leaped from somewhere within, from a nest of piping, and scrambled past me; its foot pressed on my shoulder; it peered out into the storm; it spied the body below, which had slipped from the side of the ship when I had entered the ship, no longer holding it; it seemed momentarily puzzled; it fired into the body twice more; it scrambled from the opening, turning, slipping on the steel, and slid down to the sand at the side of the ship.

I came alive, crawling through the interior hatch, which was hanging back open, fastened back, so that the Kur could have his clean shot. I slipped inside, and nearly fell, my feet scraping for a hold. I found it. I heard the Kur outside howl with rage. I tried to swing the hatch shut, to lock it, but it hung crooked on its hinges and would not close. Perhaps it had been damaged in the crash of the ship. Perhaps the Kur with whom I had trekked had, with the frenzy of a Kur’s strength, wrenched it aside, before meeting the four charges of the other Kur’s weapon. I heard the Kur’s claws swift on the steel outside, scraping, climbing. I reached for the ring at my neck. It was gone! The bit of leather, brittle, worn from the sun, had separated. I heard the snap of the hand weapon.

I looked up. It was not more than eighteen inches from my face. It snapped again. I dropped into the darkness of the ship. It was empty. The Kur howled with rage. I fell, dropping, striking objects, sliding for perhaps forty or fifty feet, until stopped by a compartment wall. I looked up. The interior of the ship was suddenly illuminated. In the cylinder above me, in the portal, his paw at the disk, stood the Kur. He looked down at me. His lips drew back. He had discarded the weapon. I looked about myself, wildly. The interior of the ship, given its attitude, seemed oddly askew. Beyond this it was not as compact as I would have expected, as filled with devices, panels and storage cabinets. It had been muchly stripped, apparently, presumably to lighten it. I saw the Kur easily, gracefully for its bulk, with its long arms, pipe to pipe, swing down toward me. When it reached my level I tried to climb upward, clinging to piping at the ship’s side. Its hand closed about my ankle and I felt myself torn from the piping. I was lifted in the air and hurled against the wall of the ship, and I fell back from the wall, falling some ten feet to the remains of a twisted, ruptured bulkhead, slipped from it and fell another five feet into a debris of scrap and wire. I crawled on my bands and knees. I heard the Kur approach. Under some pipes, below me, suddenly, I saw the ring. I fell to my stomach, my arm clawing downward. I could not reach it. I scrambled to my feet. The Kur looked down, he, too, seeing the ring. I backed away, stumbling a bit, back in the debris and wire. I looked upward, in the inclining cylinder of the ship. High above me, some sixty or seventy feet, I saw six dials. The Kur reached down with its long arm. I bent to the pile of debris and wire. The Kur’s arm was long enough to reach the ring, as mine was not, but the piping beneath which it had fallen was too closely set to accommodate the large arm of the Kur. I began to climb upward, on projections, on spaced piping, on the remains of sundered bulkheads, toward the dials. The Kur took the pipes in his hands, to bend them apart. He had separated them some five inches when he looked up. He saw me. He howled with rage. No longer did, he concern himself with the ring. Instantly he began to climb toward me. He climbed swiftly, purposefully.

I crouched on a steel beam athwart the cylinder, opposite the six dials. The first four dials were motionless. The last two were still in motion. Each dial had a single sweep. Each dial was divided into twelve divisions. The sweeps in the first four dials were vertical. I could not read the numerals on the dials.

I surmised the vertical position was equivalent to twelve or zero. It was the position, at any rate, it seemed clear, in which the devices stopped. The movement of the sweeps was counterclockwise.

The Kur was climbing toward me.

The first dial, I surmised, registered something equivalent to months, the second to weeks, the third to days, the fourth to hours. I did not know the rate of revolution of the Kurii’s original planet, nor the rate of its rotation. I had little doubt that these measurements, however, were calibrated on the movements of a world, presumably vanished, destroyed in their wars. They had destroyed one world; they now desired another.

With my teeth I tore the insulation from a part of the wire I had taken from the pile of debris and wire, coiled and, in my teeth, carried with me in my climb.

I looped the noose where the wire was naked. As the Kur climbed near me, his back to me I caught its great shaggy bead in the loop and drew it tight. It tore at the fine wire with its thick digits but they could not slip beneath it. I flung myself backward off the beam and the wire pulled the Kur from the side of the ship until it hung, struggling, I hanging a few feet below it. It flung out its paws but could grasp on nothing. It tried to hold the wire, and climb on it, or relieve the pressure on its throat, but its great paws slipped on the slender strand; then its weight began to pull me upward; I, hands knotted in the insulated portion of the wire, kicked the Kur back as it reached for me; then I was above it, being drawn by its weight to the height of the beam; the shoulders of the Kur were mantled in red; blood ran heavily from its throat, in throbbing, gigantic glots; I braced, myself, head down, feet pressed up against the beam, to hold the Kur in place; then, without warning, the wire parted; when the wire parted I was almost horizontal to the beam, trying to keep from being pulled over it, trying to hold the Kur; the force of my legs, relieved suddenly of the counter tension of the Kur’s weight, flung me back, almost to the other side of the ship, and I slid down a few feet and caught some piping. The Kur, striking four times, fell some sixty or seventy feet, to the lowest level of the ship, past the door, well below the level of the sand outside.
