<passage>:
The man at the bar was exceptionally handsome, and he knew it. So did the light-haired girl at his side, and so did the nondescript man in Everyone in the room was aware of the big young man, and most of the humans present were resentful, for he handled himself consciously and arrogantly, as if his appearance alone were enough to make him superior accustomed to adulation herself, and next to Gabriel Lockard she was almost ordinary-looking. As for the extraterrestrials—it was a free bar—they were merely amused, since to them all men were pathetically and irredeemably hideous. short man standing next to the pair—young, as most men and women were in that time, thanks to the science which could stave off decay, though not death—but with no other apparent physical virtue, for plastic surgery had not fulfilled its bright promise of the twentieth century. The drink he had been raising to his lips splashed all over his clothing ugly little man, but also a rather ridiculous one—or at least he felt was implied. And that, coming on top of Gabriel Lockard's spectacular appearance, handsome face. The man in the gray suit smiled. "Who else in any world would stand up other man's incredibly handsome young face, noted the suggestion of bags under the eyes, the beginning of slackness at the lips, and were him, she assumed he was lying, but, as a matter of fact, just then he happened to have been telling the truth. 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 and of which she still bore the reminder on one thickly made-up cheek. on the ground when the car that had been following them landed, and a short fat man was puffing toward them through the mist. young man by the light of his minilume, almost as if she weren't there looking at her intently. His small eyes seemed to strip the make-up There were no public illuminators this far out—even in town the lights were dimming and not being replaced fast enough nor by the newer models. The town, the civilization, the planet all were old and which was, of course, absurd. She had an excellent memory for faces and casually, as a by-product of some larger scheme, and her appreciation held little gratitude. perhaps he was unaware that the fat man was not a desperate or despairing individual seeking one last chance, but what was known colloquially as a flying dutchman, a man, or woman, who went from one zarquil game to another, loving the thrill of the sport, if you implied, knowing merely that it was one of those nameless horrors so deliciously hinted at by the fax sheets under the generic term of "crimes against nature." Actually the phrase was more appropriate to zarquil than to most of the other activities to which it was commonly applied. And this was one crime—for it was crime in law as well as 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 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. it was down-right shabby, the dim olive light hinting of squalor rather than forbidden pleasures. That was darkside practices. Naturally the small-town houses were more likely to patterns. The stranger, a thin young man with delicate, angular It almost seems as if he went around looking for trouble, doesn't it?" "It does indeed," the stranger agreed, coughing a little. It was growing colder and, on this world, the cities had no domes to protect them from the climate, because it was Earth and the air was breathable and it wasn't worth the trouble of fixing up. The girl looked closely at him. "You look different, but you the same man who pulled us out of that aircar crash, aren't you? And before that the man in the gray suit? And before that...?" The young man's cheekbones protruded as he smiled. "Yes, I'm all of them." who go around changing their bodies like—like hats?" Automatically she reached to adjust the expensive bit of blue synthetic on her moon-pale hair, for she was always conscious of her appearance if she had not been so before marriage, Gabriel would have taught her that. "But why do you do it? Why! Do you like it? Or is it because of Gabriel?" She was growing a little frantic there was menace here some animal who had lived and died light-years away—more closely about identify you now, even when you're ... wearing a new body there's something about you that doesn't change." from the crowd. Too bad he got married anyway," he added, his voice less impersonal, "for your sake." She had come to the same conclusion in her six months of marriage, but she would not admit that to an outsider. Though this man was hardly an in the long run, be most beneficial for my face." "Sorry," the Vinzz said impersonally, in English that was perfect except for the slight dampening of the sibilants, "but I'm afraid you cannot play." "Why not?" The emaciated young man began to put on his clothes. game is really clean." "In a town like this?" "That is the reason we can afford to be honest." The Vinzz' tendrils quivered in what the man had come to recognize as amusement through long, but necessarily superficial acquaintance with the Vinzz. His heavy robe of what looked like moss-green velvet, but might have been velvet-green moss, encrusted with oddly faceted alien jewels, swung with him. "We do a lot of business here," he said unnecessarily, for the whole The young man smiled wryly. Just his luck to stumble on a sunny game. he changing because of Gabriel, he wondered, or was he using his own discoverment and identification simply as an excuse to cover the fact that none of the bodies that fell to his lot ever seemed to fit him? Was he activated solely by revenge or as much by the hope that in the to be asked or answered. All I can tell you is that it is in good health." "Of course," the Vinzz said primly. His kind did have certain ultimate standards to which they adhered rigidly, and one of those was the 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, He looked at himself in the mirror and found he had a fine new body tall and strikingly handsome in a dark, coarse-featured way.
