As for the extraterrestrials—it was a free bar—they were merely amused, since to them all men were pathetically and irredeemably hideous. not death—but with no other apparent physical virtue, for plastic surgery had not fulfilled its bright promise of the twentieth century. hastily supplied by the management. "Then what are you running from, if not me? You can't be running from yourself—you lost yourself a while back, remember?" Gabe ran a hand through his thick blond hair. "Come on, have a drink Once the illuminators were extinguished in Gabriel Lockard's hotel suite, it seemed reasonably certain to the man in the gray suit, as he watched from the street, that his quarry would not go out again that night. So he went to the nearest airstation. There he inserted a coin in a locker, into which he put most of his personal possessions, identification was possible, for he was no one and had been no one for years. The nondescript man hailed a cruising helicab. "Where to, fellow-man?" the driver asked. "Oh...? Females...? Narcophagi...? Thrill-mills?" wanted by then. "Dice...? Roulette...? Farjeen?" "if you get up, I'll drive you home. I warn you, be more careful in the future! Sometimes," he added musingly, "I almost wish you would let Gabriel shivered. "I'll be careful," he vowed. "I promise—I'll be careful." When he was sure that his charge was safely tucked in for the night, driver to take him to the nearest zarquil game. The driver accepted the or despairing individual seeking one last chance, but what was known Playing the game was fabulously expensive it had to be to make it profitable for the Vinzz to run it. Those odd creatures from Altair's seventh planet cared nothing for the welfare of the completely alien human beings all they wanted was to feather their own pockets with interstellar credits, so that they could return to Vinau and buy many slaves. For, on Vinau, bodies were of little account, and so to them zarquil was the equivalent of the terrestrial game musical chairs. Which was why they came to Terra to make profits—there has never been big money in musical chairs as such. they had strange powers, which, not being definable, were beyond the could give an effective prison sentence to a creature whose life spanned approximately two thousand terrestrial years. And capital punishment had become obsolete on Terra, which very possibly saved the terrestrials embarrassment, for it was not certain that their weapons could kill the Vinzz ... or whether, in fact, the Vinzz merely expired after a period of years out of sheer boredom. Fortunately, because trade was more profitable than war, there had always been peace between Vinau and Terra, and, for that reason, Terra could not bar the entrance of apparently respectable citizens of a friendly planet. The taxi driver took the fat man to one of the rather seedy locales in which the zarquil games were usually found, for the Vinzz attempted to conduct their operations with as much unobtrusiveness as was possible. of the usual Vinoz set-up it was down-right shabby, the dim olive light hinting of squalor rather than forbidden pleasures. That was The Vinoz games were usually clean, because that paid off better, but, when profits were lacking, the Vinzz were capable of sliding off into darkside practices. Naturally the small-town houses were more likely to The fat man wondered whether that had been his quarry's motive in coming to such desolate, off-trail places—hoping that eventually disaster would hit the one who pursued him. Somehow, such a plan seemed too logical for the man he was haunting. to herself. "I had no idea of the kind of place it was going to be until he brought me here. The others were bad, but this is even worse. them from the climate, because it was Earth and the air was breathable and it wasn't worth the trouble of fixing up. Why! must not let herself think that way or she would find herself looking for a zarquil game. It would be one way of escaping Gabriel, but not, she thought, the best way her body was much too good a one to risk so casually. of the Moon and hurl itself upward—one of the interstellar ships embarking on its long voyage to distant suns. She wished that somehow she could be on it, but she was here, on this solitary old world in a barren solar system, with her unconscious husband and a strange man who followed them, and it looked as if here she would stay ... all three of them would stay.... "If you're after Gabriel, planning to hurt him," she asked, "why then less impersonal, "for your sake." She had come to the same conclusion in her six months of marriage, but "Why must you change again?" she persisted, obliquely approaching the subject she feared. "You have a pretty good body there. Why run the risk of getting a bad one?" "Why not?" The emaciated young man began to put on his clothes. "You know why. Your body is worthless. And this is a reputable house." "But I have plenty of money." The young man coughed. The Vinzz "In a town like this?" "That is the reason we can afford to be honest." The Vinzz' tendrils set-up spelled wealth far beyond the dreams of the man, and he was by no means poor when it came to worldly goods. "Why don't you try another town where they're not so particular?" The young man smiled wryly. Just his luck to stumble on a sunny game. win another body that approached perfection as nearly as his original casing had? He didn't know. However, there seemed to be no help for it now he would have to wait until they reached the next town, unless the girl, seeing him reappear in the same guise, would guess what had happened and tell her husband. He himself had been a fool to admit to her that how he could so casually have entrusted her with so vital a piece of information. The Vinzz had been locking antennae with another of his kind. Now they kept them from tapping a vast source of potential players. There had also never been a recorded instance of humans and extraterrestrials exchanging identities, but whether that was the result of tabu or biological impossibility, no one could tell. It might merely be prudence on the Vinzz' part—if it had ever been proved that an alien life-form had "desecrated" a human body, Earthmen would clamor for war ... for on this planet humanity held its self-bestowed purity of birthright dear—and the Vinzz, despite being unquestionably the stronger, were pragmatic pacifists. It had been undoubtedly some rabid member of the anti-alien groups active on Terra who had started the rumor that the planetary slogan of Vinau was, "Don't beat 'em cheat 'em." "Why, that's three times the usual rate!" not an important criminal in any sense of the word, was one whom the police had been ordered to burn on sight. The abolishing of capital punishment could not abolish the necessity for self-defense, and the she hadn't followed the idea to its logical conclusion. "Of course I'd go with you," she went on, now knowing she lied, "when you got your ... old body back." Sure , she thought, I'd keep going with you to farjeen houses and thrill-mills. Actually she had accompanied him to a thrill-mill only once, and from then on, despite all his threats, she had refused to go with him again. But that once had been enough nothing could ever wash that experience from her mind or her body. "You wouldn't be able to get your old body back, though, would you?" she went on. "You don't know where it's gone, and neither, I suppose, does he?" "I don't want to know!" he spat. "I wouldn't want it if I could get
