The Third Little Green Man

He was unnecessary. The first two had already convinced Shoemaker there was only one cure for his condition—and that was to get the hell away from space-ships and onto a nice red wagon.
Shoemaker sat in the open sallyport of the ship and looked gloomily at a pale blue-green seascape, parted down the middle by a ghostly shoreline. The sea was a little greener, and the land was a little bluer; otherwise there was no difference to the eye. Once in a while a tiny breeze came in from the sea, and then the stink changed from sulphur to fish.
Venus, he decided, was a pest-hole. If he'd known it would be like this, he would have socked old Davies in the eye when he came to him with his damned plans. And then he'd have got roaring drunk to celebrate his escape.
Drunk.... Boy, he'd been squiffed last night! And every night, except one horrible period when they'd found his cache and it had been three days before he could shut off the engines and make more. Thinking of that, he shuddered. Better get started early tonight; no telling when the others would be back.
He rose and went back into the stifling heat of the ship. No cooling system in the thing; that's one item he hadn't thought of. But then, to hear Davies and Burford talk, Venus was going to be a kind of Turkish paradise, full of pomegranates and loose women. Nothing had been said about the temperature or the smells.
He walked down the narrow passageway to the hold, entered one of the compartments, and stopped before a patched section of the bulkhead. The ship was practically nothing but patches, and this looked no different from the rest. But it was.
Shoemaker stuck a fingernail under the lower end of the metal strip, and pulled. The strip came loose. He got his finger all the way under and lifted. The soldered edges tore away like so much glue.
He caught the section as the top came away, and laid it aside. Behind it, in a space where plastic filler had been removed, were stacked bottles of a colorless liquid. He took one of them out and shoved it into his back pocket. Then he picked up the patch sheet and, holding it in place with one hand, took a metal-foil tube out of his pocket with the other. The gunk in the tube was his own discovery; a phony solder fluid that was pretty nearly as strong as the real thing, except that the slightest leverage would pull it loose. He smeared a thin film of the stuff all around the patch, held the sheet for a few seconds more while it dried, then stood off to examine his work. Perfect.
