"You must will take a few days and might get a little expensive." Doran's thin sharp face grinned. "You break that date, Peri. Put it off or something. I got this Martian for you, see?" "So? Since when has all Mars had as much spending money as one big-time "I cannot promise anything yet except that I will try. Now you finish "Sure, sure. But how much are those boys going to spend on any girl, even a high-level type like you? Listen, I need you just for tonight, just blank right out again. I saw him first!" hundred million dollars expense money, and they are not going to audit his accounts at home. One hundred million good green certificates, Peri's peaches-and-cream countenance began to resemble peaches and cream left overnight on Pluto. "Badger?" she asked. "Sure.

We know our export trade hasn't a chance among all your corporations unless we get some—a five-year contract...?" He heard his words trailing off idiotically, and swore at himself. "Well, good luck." The official's tone was skeptical. He stamped the supposed to find my planet a con man! He began walking, disconsolately, at random. His lizardskin shirt and black culottes drew glances, but derisive ones: their cut was forty years out of date. He should find himself a hotel, he thought drearily, but he wasn't tired the spaceport would pneumo his baggage to him whenever he did check in. The few Martians who had been to Earth had gone into ecstasies over the automation which put any service you could name on a twenty-four-hour basis. But it would be a long time before Mars had such machines. If ever. He had been standing at the table for some time before the rest of the passes he had made were unsuccessful. Earth gravity threw him off. But when he got the rhythm of it, he tossed a row of sevens. It was a "You did all right, brother," said a middle-aged lady with an obviously surgical bodice. "But—I mean—when do we start actually playing ? What happened to the "Oh. Thanks. Thanks ever so much. I, I, that is—" Matheny cursed his knotting tongue. Damn it, just because they're so much more sophisticated than I, do I have to talk like a leaky boiler? remained of his winnings. "I don't want to—I mean if you're busy tonight, Mr. Doran—" "Nah. I am not doing one thing in particular. Besides, I have never met distance, such voyages are much too expensive for us to make them for people come back saying you have given the planet just barely enough air to keep a man alive. And there are no cities, just little towns and "Yes. And it all goes to Earth and sells at 2000 dollars a fifth. But you don't think we'd drink why do you call yourselves poor?" "Because we are," said Matheny. "By the time the shipping costs have been paid on a bottle, and the Earth wholesaler and jobber and sales engineer and so on, down to the retailer, have taken their percentage, and the advertising agency has been paid, and about fifty separate to be printed on Earth, and the printer and distributor keep most of the money. We've sold some books and show tapes, of course, but only absolutely, in dollars, it doesn't amount to much when we start "Beer," said Matheny without hesitation. "Huh? Look, pal, this is on me."

But, in principle, I have told him the truth, told him of our cetera. That is just the way Earth is set up these days." Matheny's finger stabbed in the general direction of Doran's pajama three seconds of commercial time on a Lullaby Pillow 'cast. What we need, what we have to hire, is an executive who knows Earth, who's an Earthman himself. Let him tell us what will appeal to your people, and how to dodge the tax bite and—and—well, you see how it goes, that sort of, uh, thing." "But where do I start?" he asked plaintively, for his loneliness smote "It might be arranged," said Doran in a thoughtful tone. "It just might. How much could you pay this fellow?" "A hundred megabucks a year, if he'll sign a five-year contract. That's Earth years, mind you." "I'm sorry to tell you this, Pete," said Doran, "but while that is not bad money, it is not what a high-powered sales scientist gets in Newer permanently."

"You said one thing, Pete," Doran remarked. "About needing a "Okay by me. Room service can send us up an oath box right now." "What? But—but—" Matheny hung onto himself and tried to believe that he had landed on Earth less than six hours ago. In the end, he did call room service and the machine was trundled in. Doran swallowed the pill and donned the conditioner helmet without an you may tell me under security, now or at any other time," he "I know." Matheny stared, embarrassed, at the carpet. "I'm sorry to—to—I mean of course I trust you, but—" "Forget it. I take a hundred security oaths a year, in my line of work. " Huh?
