Where were the controls of this thing? Ah, way up forward. Best look at those. There just might be a chance that he could change setting and, in extremis, simply pull the wires loose.

He walked up along the plates. His plane's lights were bright even up front.

There was the setting box. A “preset,” and there was the console one set the preset plates in. Fat lot of good the console was. Like a stamping machine. He looked at the preset box. One usually fed preset plates into the side and latched the box. Here, too. But this one?

It was armored.

It had a keyhole. He looked around but there was no key left behind.

Cables? All armored. And they even went into the preset box with an armored connection.

Crud was all around. Lord, this thing was old! It was only clean around the preset box. He supposed they had cleaned it up to set it.

A vague feeling of unease troubled him. Completely aside from his intentness on stopping this drone, there was something odd in this place. He looked down toward the plane. The deep recesses between the frames were in complete darkness.

Zzt, unseen in a recess not six feet away, crouched back in desperation. His wits were racing. What did he know about Tolneps? Shortly after he had graduated from Mechanics College on Psychlo he had done a duty tour on

Archiniabes where the company had mines. It was in this universe. The system star was the double star he sometimes saw in winter on this planet; the smaller star of the “dumbbell” had a weight so dense that a half cubic inch of it here would weigh one ton. A minesite had been wiped out utterly by a Tolnep raid. They came from somewhere near the star cluster he often saw here. They had mastered time control and could hold it frozen and their ships made long piratical voyages. The company had analyzed several of their dead bodies. What did he remember about them? What weakness? He could think only of strengths. Their bite was deadly poison. They had a body density comparable to iron. They were immune to Psychlo gas. They couldn't be killed with an ordinary blast gun. Weaknesses, weaknesses, weaknesses? If he didn't recall them he would never get out of this alive. Never.

This one was walking back down past him now. He shrank against the ship skin. It didn't see him here in the darkness.

Then he remembered. Their eyesight! That was why they always wore face masks. They saw in infrared only and had to have a filter plate. They went totally blind when subjected to shorter wavelength light and they could be killed only with ultraviolet weapons. They were intensely allergic to cold and had a body heat of around two hundred degrees, or was it three hundred? No matter, he was on to it. It was eyesight. Without its faceplate that creature would be blind.

Zzt planned carefully. The instant he got a chance, he would knock off the faceplate, leap forward, and claw the thing's eyes out, somehow avoiding the poison teeth. Zzt's paw slid down to the side of his boot and he got out his trusty big wrench. He could throw it like a projectile. Don't hit the body, hit the side of the mask!

Zzt then drew from his breast pocket the small round mirror with its long handle that he used to look in the back of connections or the underside of bearings. He carefully extended the mirror around the edge of the frame, praying to the crap nebula the thing wouldn't notice it. He began to watch the creature.

Jonnie found it very hard to walk in the rolling drone. The floor plates were not meant for walking and had gaps on both sides.

He went clear to the back end of the drone, quite a walk in itself. He looked at the strange honeycomb. It was bottle racks for additional load. He crawled in the entry port. Maybe some cables or something overlooked would be in there. He could barely get through the port and wondered how a

Psychlo could, until he realized it was just for canister loading of the racks. Clumsy. Just racks. Bad design. The ports were toward the center and it was only blank bulkhead on either side. Nothing else here.

He went back toward the forward end. He stopped just beyond the ship. He thought very hard. He could see nothing that could be pulled apart, nothing that could be blasted apart. He could even blow up his ship in here and nothing would happen.

No controls. The drone was not made to be flown but just set and launched. Not even the remote Terl had shown him would do anything now.

Rolling like a huge ungainly drunk, the thing continued on its way with death in its jaws, insensate, invulnerable.

He wasn't seeing so well again. Blood had started flowing when he crawled into the hole back there and he'd knocked his mask. He lifted his hands to the mask, turning sideways to lessen the blast from the door. He was reaching for the edge of his jacket to wipe it off.

With the impact of a bullet the mask was hit!

It flew from his hand.

Something had almost broken his left thumb.

There was motion about thirty feet away.

Mountain training and a hunter's life had left nothing wanting in Jonnie's reactions.

The action of dropping to one knee, drawing, and firing the blast gun did not take more than a third of a second.

He fired at the mass that had begun to come at him. The shots drove it back with sheer force.

Again and again he fired.

The thing, whatever it was, moved back into the cover of the rib frames near the preset.

There was something or someone in here with him. He had walked right past it twice when he went to the preset box.

Jonnie protested a little at not heeding his instincts earlier. He had felt some presence. That was the worst part of wearing air masks. It denied one's sense of smell. And he could smell it now. Despite the cold air and the rust motes Jonnie could smell a Psychlo.

He rose cautiously, holding the gun, and backed toward his plane to get a bit more distant. A Psychlo was pretty strong stuff not only to smell but to deal with in any wrestling match. He recalled having to wait for Thor before he could approach within arm's length of Terl. Psychlos could crush one with ease. Which Psychlo was this? Did he know him?

Zzt, pressed up against the skin, was trying to keep from vomiting with contempt and disgust. Only what it would do to his breathe-mask prevented him.

It wasn't the blast gun shots. Yes, those that hit had bruised him and thrown him back, and a few feet closer they might have disabled him.

It was his own reaction to change. Here he had been in abject funk and all the while it was only the animal. Terl's animal!

A surge of hatred and fury followed his nausea. He almost emerged from the recess and plowed straight in. But a blast gun stung. And the dumb twit didn't even have it on penetration, only on blast. Typical.

That this animal had subjected him to such terror he could not forgive. Why, he had nearly killed it once on the tractor with a remote. He really should have killed it. He should have taken a blast rifle out that day. Who would have noticed in all that fire?

Nothing but the animal! A puny, soft, undersized, slug-white, stupid animal had scared him like that! He quivered with rage. His nausea faded.

Desire for information overrode his kill lust at this moment. Maybe this was some new plot of Terl’s. Damn

Terl!

Zzt got himself under control enough to speak. “Did Terl send you?”

Jonnie tried to place the voice. Hard to do the way they talked through a face mask. The masks had sound amplification patches on their sides but voices got muffled, low as they were. He could ask; Psychlos were very arrogant.

“Who are you?” said Jonnie.

“You went through all that at the tractor and you don't even remember who I am! Stupid dimwit. Answer me!
