After setting the locker to respond to the letter combination years. The nondescript man hailed a cruising helicab. "Where to, fellow-man?" the driver asked. "I'm new in the parish," the other man replied and let it hang there. "Oh...? Females...? Narcophagi...? Thrill-mills?" "Games?" the driver finally asked, although he could guess what was wanted by then. "Dice...? Roulette...? Farjeen?" "Is there a good zarquil game in town?" The driver moved so he could see the face of the man behind him in the thrill-mill." He gave a sigh that was almost an audible shudder, and which the driver misinterpreted as an expression of ecstasy. "Each time, eh? You're a dutchman then?" The driver spat out of the window. "If it wasn't for the nibble, I'd throw you right out of the "Of course. You'll need plenty of foliage, though." It was a dark and rainy night in early fall. Gabe Lockard was in no the dripping grass first, but stopped and deliberately examined the young man by the light of his minilume, almost as if she weren't there " Mrs. Otherwise, darkness surrounded the three of them. lights were dimming and not being replaced fast enough nor by the newer models.

"Aren't you going to introduce your—your "I don't know who he is," Gabe said almost merrily, "except that he's no friend of mine. Do you have a name, stranger?" "Of course I have a name." The fat man extracted an identification card from his wallet and read it. "Says here I'm Dominic Bianchi, and Dominic Bianchi is a retail milgot dealer.... Only he isn't a retail milgot dealer any more the poor fellow went bankrupt a couple of weeks ago, and now he isn't ... anything." casually, as a by-product of some larger scheme, and her appreciation held little gratitude.

I warn you, be more careful in the the fat man checked his personal possessions. He then requested a taxi driver to take him to the nearest zarquil game. The driver accepted the commission phlegmatically. Perhaps he was more hardened than the others had been one zarquil game to another, loving the thrill of the sport, if you could call it that, for its own sake, and not for the futile hope it extended and which was its sole shred of claim to moral justification. Perhaps—and this was the most likely hypothesis—he just didn't care. Zarquil was extremely illegal, of course—so much so that there were many legitimate citizens who weren't quite sure just what the word "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 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. When the zarquil operators were apprehended, which was not frequent—as 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 However, beggars could not be choosers. The fat man paid off the heli-driver and entered the zarquil house. "One?" the small green creature in the slightly frayed robe asked. patterns. The stranger, a thin young man with delicate, angular features, made no attempt to follow. Instead, he bent over to examine "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 are The young man's cheekbones protruded as he smiled. "Yes, I'm all of them." "Then what they say about the zarquil games is true? There are people hair, for she was always conscious of her appearance Do you like it?

Sure, nobody's of foliage." expensive—that's all. Bad landing for the guy who gets it, but then it was tough on me too, wasn't it?" "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 shrugged. "I'll pay you twice the regular fee." The green one shook his head. "Regrettably, I do mean what I say. This game is really clean." "In a town like this?" "That is the reason we can afford to be honest."

The man rubbed his chin thoughtfully. "How much?" "Thirty thousand credits." "Why, that's three times the usual rate!" "The other will pay five times the usual rate." "Oh, all right," the delicate young man gave in. It was a terrific risk he was agreeing to take, because, if the other was a criminal, he tall and strikingly handsome in a dark, coarse-featured way. Nothing to police had been ordered to burn on sight. The abolishing of capital punishment could not abolish the necessity for self-defense, and the maybe I'll be able to get away with it.
