GRIFTERS' ASTEROID By H. L. GOLD Harvey and Joe were the slickest con-men ever to gyp a space-lane sucker. Or so they thought! could devote his life to improving this lonely worldlet is obviously a "For a very good reason, sir. Patience is the virtue that will be rewarded with the key to these fourth dimensional broadcasts. A man who person with unusual patience." Characteristically, Harvey Ellsworth tried to maintain his dignity, though his parched tongue was almost hanging out. But Joe Mallon, with In their hectic voyages from planet to planet, the pair of panacea purveyors had encountered the usual strange life-forms. But never had remaining pair. The bartender, a big man resembling the plumpish Harvey in build, was leaning negligently on the counter, ordering this proclaiming this magic medicine the sole panacea in the entire history of therapeutics." Harvey's eyes bulged. Joe gulped. "That—that's robbery!" the lanky man managed to get out in a thin quaver. The barkeeper shrugged. "When there ain't many customers, you gotta make more on each one. Besides—" "Besides nothing!" Joe roared, finding his voice again. "You dirty crook—robbing poor spacemen! You—" "You dirty crook!" Joe roared. "Robbing honest spacemen!" Harvey nudged him warningly. "Easy, my boy, easy." He turned to the bartender apologetically. "Don't mind my friend. His adrenal glands are sometimes overactive. You were going to say—?" The round face of the barkeeper had assumed an aggrieved expression. "Folks are always thinkin' the other feller's out to do 'em," he said, unconscionable interjection of a middleman between Nature and man's thirst." Johnson's response almost floored them. "Who said anything about "Now do you see, my hot-tempered colleague?" said Harvey as he and Joe "What's this doing here?" Harvey asked, puzzled. "I thought Johnson had His mouth went wry. "Bitter! He uses only one pool, the sweet one! The only thing that needs purifying around here is that blasted mayor's conscience." Him and me are the whole Earthman population of Johnson City." Johnson's eight-foot son, topped by a massive roof of sun-bleached hair atmosphere. The pursuit of vengeance, Harvey realized, had taken a quick and unpleasant turn. Something shrewd was called for.... "Of course," replied Harvey calmly. "Any fool knows the first symptoms of the disease that once scourged the universe." every year, and I ain't hankering to have it in an off-season. Get him out of here!" his gigantic offspring were cowering across the room, trying to breathe in tiny, uncontaminating gasps. "It sells itself." "'Course, I'd expect a considerable reduction if I bought a whole "Medicine," Harvey propounded, "should taste like medicine." To Joe he swindled to the tune of ten buckos a liter? Where would our profit have been, then? No I had to use the bitter free water, of course." Harvey looked reprovingly at his gangling partner. "Did Johnson ask to the same that swindler cheated us, besides whatever other funds or valuables he possesses. We could not be content with less." Harvey stopped filling bottles and looked up pensively. "I have every hope of luring away the profitable monstrosity. Apparently you have also surmised the fortune we could make with him. At first I purpose to exhibit him on our interplanetary tours with our suckers. Later, a brief period of demonstrating his abilities on the audio-visiphone. Then our triumph—we shall sell him at a stupendous figure to the zoo!" Joe was still dazed by that monetary vista when he and Harvey carried and asked: "You gents eaten yet? The restaurant's open now." Harvey and Joe looked at each other. They hadn't been thinking about food at all, but suddenly they realized that they were hungry. chance of company. Genius, the six-armed native, appeared from the dingy kitchen with two menus in one hand, two glasses of water in another, plus napkins, silverware, a pitcher, plates, saucers, cups, and their cocktails, Harvey and Joe studied the menu critically. The prices were was as extraordinary as the meal itself. With four hands, Genius played deftly upon a pair of mellow Venusian viotars hostess's season a riotous success, which should be worth a great sum to women like Mrs. van Schuyler-Morgan, merely for his hire." "Think of a fast one fast," Joe agreed. "You're right." "But I dislike having to revise my opinion of a man so often," complained Harvey. "I wish Johnson would stay either swindler or honest merchant. This dinner is worth as least twenty buckos, yet I estimate our check at a mere bucko twenty redsents." fantastic, idiotic figure— three hundred and twenty-eight buckos !" Harvey focused on the microscopic print, and his face went pasty with "restaurateur," pocketed it. Meanwhile, Harvey tipped Joe the sign to made you forget those elements of human wisdom that have entered the folk-lore of your native planet. Such as, for example: 'It is folly to kill a goose that lays golden eggs,' and 'Penny wise is pound foolish.'" "I don't get the connection," objected Johnson. "Well, by obliging us to pay such a high price for your dinner, you put out of your reach the chance of profiting from a really substantial deal. My partner and I were prepared to make you a sizable offer for the peculiar creature you call Genius. But by reducing our funds the way you have—" carelessness. "Perhaps you wouldn't have accepted it, anyway." "That's right," Johnson came back emphatically. "But what would your offer have been which I would have turned down?" "Which one? The one we were going to make, or the one we can make now?" "Either one. It don't make no difference. Genius is too valuable to sell." "Oh, come now, Mr. Johnson. Don't tell me no amount of money would tempt you!" "Nope. But how much did you say?" "Ah, then you will consider releasing Genius!" it's the same as having a lot of things. Because, if you've got money, you can buy this and that and this and that and—" asked with the suspicion of a man who has seen human nature at its worst and expects nothing better. "We must not be selfish, my boy," Harvey said nobly. "We have had our chance now we must relinquish Fate to the hands of a man who might On a larger and heavier world than Planetoid 42, Johnson's curiosity would probably have had weight and mass. He was bursting with questions, but he was obviously afraid they would cost him money. For his part, Harvey allowed that curiosity to grow like a Venusian amoeba political speech-makers." "Do not jump to hasty conclusions," Harvey cautioned. "Another word, and I shall refuse you the greatest opportunity any man has ever had, with the sole exceptions of Joseph, myself and the unfortunate inventor of this absolutely awe-inspiring device." He has spurned our generosity. We have now the chance to continue our study, which I am positive will soon reward us with the key to an enormous fortune." turn it down. I hated to give it up after working on it for three whole saying I'll buy, but what is it I'm turning down?" a sensitive soul like his could stand only so much. And the combination of ridicule and failure to solve the mystery caused him to take his own life."
