Altairian stopped, producing a huge key ring from some obscure "Do they think logical." Zeckler's eyes flashed, and a huge grin broke out on his cubicle. "Not much to offer you," he said slyly, "but it's the best I can do under the circumstances." I read." "Whatever are you talking about?" "It was a Greek, I think—" Meyerhoff stared at him. "Oh, come now. Have you gone off your rocker completely? You've got a problem on your hands, man." rock. "Oh, yes. You had something else to say. Well, go ahead and say it." know what brotherhood means, nor humanity, either. Bread that?" Zeckler's eyes widened. "What do you mean, fool? So I spend a couple of weeks in this pneumonia trap. The deal was worth it! I've got three million credits sitting in the Terran them up. Three million credits—do you hear? That's enough to set me up for life!" Meyerhoff nodded grimly. " "Really," said Harry Zeckler loftily, "it was so obvious I'm amazed that it didn't occur to me first thing." He settled himself Rocket and grinned at the outline of Altair IV looming larger "And take the chance of being overheard? Don't be silly. simple for you.

"They'll probably drop a little fine on me and let me go." "A little fine of one Terran neck." Meyerhoff grinned nastily. "You've committed the most heinous crime these creatures can a trading alliance with Altair I, and that includes uranium, too. "Ah, well. After all, the Trading Alliance was outlook, wasn't it? What a pity!" He clucked his tongue sadly. "Me, he said weakly. "Nothing like a good lawyer to handle a trial." " Lawyer? appeared in his eyes. "Yes, I think you will. I'm quite sure of chuckled. "I'm your advisor, old boy. Nothing else. I'm here to keep you from botching things up still worse for the Trading Commission, that's all. I wouldn't get tangled up in a mess it, in fact. Won't cost you a cent, either." trial. The Altairians weren't any too happy to "Eh?" Not me! Oh, no. Sorry, but no thanks." Meyerhoff Not too much—just three million credits." Zeckler went white. "But that money was in banking custody!" "Is that right? My goodness. You don't suppose they could was awfully silly—until they got their money back, of course. In a way, he thought, it was a pity to see such a change in the lint fleck from his lapel, and looked up at Zeckler slyly. "That—uh—jury where rich and unexploited trading ground was uncovered, it have lost those papers, do you?" Meyerhoff grinned at the " "Oh, yes. Didn't I tell you? Conspiring to undermine the authority of the Terran Trading Commission. Serious charge, But occasionally a situation arose where the civilization and with them.

Thought a trial Zeckler shrugged again. "The simplest, tiredest, moldiest old racket that ever made a quick nickel. Remember the old Terran gag about the Brooklyn Bridge? The same thing. Only they're not so dull. You'd have found out that they're marsupials, as long as it benefits them as individuals." Meyerhoff grinned at the little man's horrified face. "Never too. You've probably never heard that there are just too many Altairians here for the food their planet can supply, and their doesn't grow here. And consequently, land is the key factor in their economy, not money nothing but land. To get land, it's every man for himself, and the loser starves, and their entire legal and monetary system revolves on that principle. They've built up the most confusing and impossible system of barter and trade imaginable, aimed at individual survival, with land as the value behind the credit. That explains the lying—of course they're liars, with an economy like that. They've completely missed the concept of truth. Pathological? You bet system built around it." Zeckler snorted. "But how could they possibly have a legal system? I mean, if they don't recognize the truth when it slaps them in the face?" Meyerhoff shrugged. "As we understand legal systems, I Meyerhoff sighed. "You've got twelve mad Altairians in your hair. You've got a mad planet in your hair.

It's stupid, to them, silly, a mark of Altair from my homeland on Terra. I—I landed on Altair II, planet, at the hands of those barbarians. The conspiracy is theirs, not mine.
