That night I turned on my hard prison cot until my bones were so much jelly, trying to figure that steal. The next morning I got up burning with this fever for information, only to find that Pard had got himself put in solitary for mugging a guard, and that really put the heat on 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. "Jupiter!" I goggled at him. "Akroida! Who's she?" 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. "Akroida," he explained in his own sweet time, "is the queen-scorp of them idiotic scorpions that lives on Jupiter. I sold her the Halcyon Diamond that disappeared from the World Museum five years ago, remember?" He winked broadly. "It come from Mars in the first place, you know. Mars! What a place fer jools! Damn desert's lousy with 'em, if it wasn't so much trouble to dig 'em out--" He went off into a dream about the rocks on Mars but I jerked him back. "You mean those scorpions have really got brains?" "Brains!" he snorted. "Have they got brains! Why, they're smarter than people! And not ferocious, neither, in spite of how they look, if you just leave 'em alone. That's all they want, just to be left alone. Peace an' quiet, and lots of methane and ammonia and arsenic, that's fer them. Besides, the space suit rig you got to wear, they can't bite you. Akroida's not a bad old girl. Partial to arsenic on her lettuce, 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 them emeralds." I went back to my cot that night, and this time instead of biting my nails, I bit myself. So I faced it. Casey Ritter lost his nerve, and along with it, the chance of a lifetime. A better man than me had already penetrated the Great Red Spot of old Jupiter and come out alive. That thought ate me to the quick, and I began to wonder if it was too late, after all. I could hardly wait for morning to come, so that I could pry more information out of Pard Hoskins.
