<passage>:
Harvey and Joe were the slickest con-men ever five buckos for a glass of water—and got it! no dignity to maintain, lurched across the rubbish-strewn patch of land that had been termed a spaceport. When Harvey staggered pontifically into the battered metalloy saloon—the only one on Planetoid 42—his tall, gangling partner was already stumbling out, mouthing something incoherent. They met in the doorway, violently. Joe reeled aside, and Harvey saw what had upset his partner. He stared, speechless for once. In their hectic voyages from planet to planet, the pair of panacea remaining pair. The bartender, a big man resembling the plumpish Harvey in build, was leaning negligently on the counter, ordering this Without a word, the bartender reached under the counter, brought out two glasses of water. The interplanetary con-men drank noisily, asked for more, until they had drunk eight glasses. Meanwhile, the bartender Harvey and Joe were breathing hard from having gulped the water so "Yeah?" said the bartender disinterestedly, polishing the chaser Harvey grinned puzzledly. "We didn't take any whiskey." "Might as well. Water's five buckos a glass. Liquor's free with every Harvey's eyes bulged. Joe gulped. "That—that's robbery!" the lanky man 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 was chargin' feller critters for water just out of devilment? I charge more to charge for water than it does for you to pay. I just got to, them. The planetoid man worked the pump while the mayor intently watched the crude level-gauge, crying "Stop!" when it registered the Harvey bravely counted off the bills. He asked: "But what are we to charging you for battery water? You can have all you want for nothing. It's just the purified stuff that comes so high." After giving them directions that would take them to the free-water pool, the ponderous factotum of Planetoid 42 shook hands and headed back to the saloon. His six-armed assistant followed him inside. "Now do you see, my hot-tempered colleague?" said Harvey as he and Joe "Just the same," Joe griped, "paying for water isn't something you can a faint suspicion alive in him. So he called Harvey and they went to They rushed back to the first pool, where Joe again tasted a sample. unpleasant turn. Something shrewd was called for.... "Joseph!" he exclaimed, looking at his partner in alarm. "Don't you gently crossing. He sagged against the door frame, all his features drooping like a bloodhound's. "Bring him in here!" Johnson cried. "I mean, get him away! He's coming down with asteroid fever!" "Of course," replied Harvey calmly. "Any fool knows the first symptoms ?" demanded Johnson. "I come down with it every year, and I ain't hankering to have it in an off-season. Get him out of here!" "In good time. He can't be moved immediately." "Then he'll be here for months!" Harvey helped Joe to the counter and lifted him up on it. The mayor and Instead of replying, Harvey hurried outside to the ungainly second-hand rocket ship in the center of the shabby spaceport. He returned within a When Joe tried to pull away, Harvey was inexorable. He made his partner Joe recoiled. "I'm fine now!" he cried, and sprang off the bar to prove "We do not sell this unbelievable remedy," Harvey replied with dignity. Harvey took a glass from the bar and poured him a generous sample. The "Medicine," Harvey propounded, "should taste like medicine." To Joe he With Joe stumbling along behind, he left the saloon, crossed the clearing and entered the ship. As soon as they were inside, Joe dropped mind you. Was I to mix the extract with the water for which we had been I had to use the bitter free water, of course." Harvey looked reprovingly at his gangling partner. "Did Johnson ask to "Okay, okay," Joe said. "But you shoulda charged him more." Harvey stopped filling bottles and looked up pensively. Joe was still dazed by that monetary vista when he and Harvey carried down carefully. Then he took the elaborate bottle-opener Harvey gave out the money into Harvey's hand, at a moderate rate that precariously Harvey and Joe looked at each other. They hadn't been thinking about "It's only water we were short of," Harvey said apprehensively. "We've "Your hospitality," said Harvey, "depends on the prices you charge." Swiftly, Harvey conned the possibilities of being bilked again. He saw chance of company. Genius, the six-armed native, appeared from the dingy kitchen with Harvey and Joe studied the menu critically. The prices were complained Harvey. "I wish Johnson would stay either swindler or honest As if on cue, Genius came out and put the check down between Joe and Harvey. Harvey picked it up negligently, but his casual air vanished in !" Johnson didn't answer. Neither did Genius "You can go to hell!" Joe growled. "We won't pay it!" Johnson sighed ponderously. "I was afraid you'd act like that," he said with regret. He pulled a tin badge out of his rear pocket, pinned it on his vest, and twisted his holstered gun into view. "Afraid I'll have to ask the sheriff to take over." "restaurateur," pocketed it. Meanwhile, Harvey tipped Joe the sign to "Well, by obliging us to pay such a high price for your dinner, you put "It doesn't matter any longer," Harvey said with elaborate "Oh, come now, Mr. Johnson. Don't tell me no amount of money would tempt you!" Harvey was quick to pay out, for this was a genuine windfall. Then he Harvey forcibly removed his eyes from the native, who was clearing off Joe's face grew as glum as Johnson's had been. "Aw, Harv," he protested, "do we have to sell it? And right when I thought we were getting the key!" have more success than we. Go, Joseph. Bring it here." Unwillingly, Joe turned and shuffled out. 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 "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 Harvey nodded in relief. "We have attempted to repay our host, Joseph. He picked up the radio and began walking toward the door. "Now, hold on!" the mayor cried. "I ain't Again Harvey smashed his fist down. "Do you dare to repeat the scurvy "Why, I don't know," Johnson said in confusion. "For three years, Joseph and I lost sleep and hair, trying to detect the simple key that would translate the somewhat metamorphosed 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."
