and sewed up tight. Sure, the crystals are deadly, but I was smuggling them legitimately, in a manner of speaking, for this doctor to experiment with. He wasn't going to sell them for dope. But—and this was the 'but' that was likely to deprive the System of my activities—even experimenting with them was illegal even if it needed to be done also, I had promised not to rat on him before taking the job. I didn't get it at first. I'd argued with 'em, but inside I'd been all set for the sentence, and even sort of reconciled to it. I could even dried-up straw, joined his fingertips carefully, cleared his scrawny throat, and told me what for. caper: Had it been just a trap to lead me straight to this? I hadn't been able to figure how they'd cracked my setup.... At the thought my larynx froze up tight. This was worse than I'd thought. Government men trapping me and then beaming at me. And a full pardon. And a reward. Oh, no! I told myself, it wasn't possible. Not when I already had more counts against me than a cur has fleas. Not unless it was a straight suicide mission! Crude, but it was all I could squeeze out. I squeezed out more when I saw those pictures, though. Those the great Casey Ritter, daredevil of the Solar System!" he sneered. "Never loses a bet, never turns down a dare!" I shuddered. "You're telling that one! And besides, a man's got to draw They were really stumped. They hadn't expected me to take this attitude at all. No doubt they had it figured that I'd gratefully throw myself won't reach in and nip off an arm or leg while he's got his back turned. How stupid could they get? chummily and snapped a salute at the guard. It makes me grind my molars now to think of it. The way that bunch of stuffed shirts in the S.S.C. made a gold-barred chimpanzee out of me has broken my spirit and made a pass at the Killicut Emeralds, that's all, and got nabbed." eggs, an even dozen of 'em and flawless, I'm a-shoutin', not a flaw!" His eyes watered at the memory, yearning like a hound-dog's over a fresh scent. mad, and if Pard had really got near those emeralds, he should be nothing but a heap of cleaned bones by now. Either he was the world's champion liar or its bravest son, and either way I took my hat off to him. He looked loftily past me. "Sorry. Gotta keep that a secret. Likewise where I cached 'em." My jaw must've been hanging down a foot, because I'd just been playing along with him, not really believing him, and now all of a sudden I me. I chewed my fingernails down to the quick by the time he got out a week later. By that time he really had me hooked. I'd of sworn he was leveling with me. But he wouldn't tell me how he'd worked the steal. Instead, he opened up on the trade he'd booked for the string. He said, "When I chisel me way outa this squirrel cage, I'm gonna hit fer good old Jupe and sell 'em to Akroida. She's nuts about jools. What that old girl won't give me fer 'em—" He whistled appreciatively, thinking about it. He looked at me as if I hadn't yet got out from under the rock where he was sure I'd been born. "Don't you know nothin', butterhead?" From him I took it. I even waited patiently till the master spoke again. The memory still makes me fry. so I brought her a hundred pounds of the stuff, an' she went fer that almost like it was diamonds, too. Did I rate around there fer awhile!" He sighed regretfully. "But then I went and made her mad, an' I'm kinda persona non grata there right now. By the time I gnaw outa this here cheese trap, though, I figger she'll be all cooled off and ready fer nails, I bit myself. So I faced it. Casey Ritter lost his nerve, and For three more days I worked down my knuckles, my nails being gone, while I sat around all hunched up, wondering feverishly if Pard would make a deal about those emeralds. Then I broke down and sent out a letter to the S.S.C. The Big Sneer of the conference table promptly dropped in on me, that was good training, so I sneered right back at him, explained the caper, and we both paid a visit to Pard. In two days the deal was made and the caper set up. There were a few bits of info that Pard had to an audience with the old rip." He shook his head slowly. "The kid that took me in was colorblind, so I didn't have no warning at all. I found out that them scorpions can't stand yeller. It just plain hadn't helped me, they'd of done it, too. And Akroida claimed I done it a-purpose to upset her." Then he winked at me. "But then I got off in a corner and cooked up though. She wouldn't give me another audience. It's in the stuff they cleaned outa me room: a poiple bottle with a bright green stopper." He ruminated a few minutes. "Tell you what, chump. Make them shell out slobbering. But the Big Sneer of the S.S.C., the fellow that had got me into this caper, was right there to take the joy out of it all and to remind me that this was public service, strictly. "These—" he had proclaimed with a disdainful flourish, like a placer miner pointing to a batch of fool's gold—"These jewels are as nothing, them. And be assured that if you're man enough to effect the trade—" He paused, his long nose twitching cynically—"IF you succeed, your reward will be triple what you could get for them in any market. Added to which, IF you succeed, you will be a free man." That twitch of the nose riled me no little. "I ain't failed yet!" I snarled at him. "Just you wait till I do, feller!" I slipped the string of emeralds back into its little safe. "Instead of sniping at me, why poor sinner's map was made of shell, and he wasn't responsible for its expression. I tapped back very politely that he must be mistaking me for someone that there might be such a thing as being too popular in Scorpdom, but I thrust this sneak-thief idea back into limbo. Taking advantage of his condition, I boldly tapped out, "How's about I tried to back off from him a bit, but the ship stopped me. "I'm Casey I breathed again. How simple could I get? He'd already mistaken me for Pard, hadn't he? Then I remembered something else. "How come you aren't mandibles and other embellishments calculated to interest my hosts. Whether it interested them or not, it was plenty uncomfortable for me. eyeballs felt paralyzed. Pard was right again. These critters had brains. And my S.S.C. persecutor was right, too. That anti-grav secret was worth more than any string of rocks in the system, including the Killicut Emeralds. what about Casey Ritter, who hadn't cultivated even a feather? of all that space dropping away, I clutched at his shell and nearly dropped the arsenic. But he didn't have any brakes I could grab, so he ducked his head and fearfully waited.
