anything. "They can identify the organisms," I pointed out. "Sure. Easy. But how do they know where he picked them up? They're laying all around outside the domes here on Mars ever since the first assault by the aliens twelve years ago. Nobody's had time to decontaminate this whole planet like they did Earth. Easiest thing in the world for a new officer on Mars to take a little sight-seeing excursion outside the domes and to be a little careless." "There would be an epidemic if he brought back a lot of spores," I suggested. "Besides, it's out of bounds to leave the dome." Spender shook his head. "You can get around that out-of-bounds business without any trouble," he said. "And there are decontamination chambers in the air locks, which would clean up anything he brought in; so there would be no epidemic. The exposure would take place outside of the domes—say if he opened his helmet to smell the perfume of the famous hypnotic marspoppy, or something like that. Then he would be infected, and after that it's non-contagious. All we need is somebody to buddy up to him, and take him out there. Nature and the poppy will do the rest." "Look," I said angrily, "cut that stuff out, Spender. If you're looking to me to disable the guy, forget about it. I won't. And I'm telling you right now that if I find anybody else does, I'll report it." For once Spender laughed. He turned to face me, and his blue eyes were dancing in his scarred, old face. He was laughing at me and my belligerent righteousness, but the real joke, of course, was that unless somebody actually caught him talking Frendon into going out there, there wouldn't be the slightest chance of proving he had done it. It was the simplest thing in the world to sneak out and back without being observed, and we both knew it. "All right," I said then. "Have your laugh, Spender. And you, too, Harding. I don't like the nut we've got any more than you do, but what you're talking about is mutiny and murder—" "Oh, he wouldn't necessarily die," Harding commented thoughtfully. "If he gets the serum within a few hours of the first symptoms, he probably would be just a very sick man for about a month. Too long to take the ship out with us when we go." He grinned at me. "And as for mutiny, nobody would be using any physical force on him. Nor—when you come right down to the specific matter of his commanding his ship—would there be any moral force employed either."
