He would have liked to say it was his suggestion originally, but it would have been too presumptuous. He was talking to an Earthman, who "Yes?" Matheny faced around, shivering with his own tension. who wish to leave. They wouldn't be able to see the Teamsters Hour on Mars, would they?" "Oh, we don't expect immigration," said Matheny shyly. He was a fairly young man, but small, with a dark-thatched, snub-nosed, gray-eyed head that seemed too large for his slender body. "We learned long ago that no one is interested any more in giving up even second-class citizenship on Earth to live in the Republic. But we only wanted to hire——uh, I mean engage—an, an advisor. We're not businessmen. We "Thanks," said Matheny, "but, you see, I—we need—that is.... Oh, He backed out of the office. Phobos! he thought wildly. temperature wasn't too far below zero. Why did they tap me for this job? he asked himself in a surge of homesickness. He, Peter Matheny, was no more than a peaceful professor of his government before now—in fact, the Red Ankh Society had been his idea—but still he was at ease only with his books and his chess and his mineral collection, a faculty poker party on Tenthday night and an , thought Matheny, greatest commercial empire the human race has ever seen, and I'm supposed to find my planet a con man!

Matheny would have found a few spins of roulette soothing: it was always an intellectual challenge to work out the system by which the management operated a wheel. But more, he would have been among people he understood. The frightful thing about the Earthman was the way he seemed to exist only in organized masses.

No, he didn't want to bother learning something new. He decided that the roulette wheels were either honest or too deep for him. He'd have to relax with a crap game instead. congregation really noticed him. Then it was with awe. The first few passes he had made were unsuccessful. Earth gravity threw him off. This is a church!" "Oh—I see—excuse me, I, I, I—" Matheny backed out of the crowd, "Oh. Thanks. Thanks ever so much. I, I, that is—" Matheny cursed Damn it, just because they're so much more sophisticated than I, do I have to talk like a leaky boiler? The helpful Earthman was not tall. He was dark and chisel-faced and sleekly pomaded, dapper in blue pajamas with a red zigzag, a sleighbell Matheny had yet heard. "Yes. Yes, I am. M-my name's Peter Matheny. I, I—" He stuck out his forgot this was a church. Never mind the chips. No, please. I just want Matheny sighed. "A drink is what I need the very most." They walked back to the deaconette's booth and Matheny cashed what 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 "There aren't many of us on Earth," agreed Matheny. "Just a small "We can't afford it," said Matheny. "What with gravitation and "Oh," said Matheny. He felt a certain guilt.

"Because we are," said Matheny. "By the time the shipping costs have "It was our mainstay," admitted Matheny, "but it's been overworked. "Of course," said Matheny bitterly. "We offer the most liberal "Beer," said Matheny without hesitation. frank with me. I like a man that is frank." Matheny shrugged. "I haven't told you anything that isn't known to Of course I haven't. I've not so much as mentioned the Red Ankh, for instance. But, in principle, I have told him the truth, told him of our need for even the secret operations do not yield us enough. The beer arrived.

The walls of the booth "By all means." Matheny disposed of his last beer. "I could use some ," said Matheny.
