JUPITER'S JOKE the great red spot of terrible Jupiter. didn't foul me with this trip to good old Jupiter. Then I croaked, "Jupiter! What for? Are you running outa space in stir? court didn't seem important just then. Jupiter was worse than the pen, a lot worse. Jupiter was a death sentence. the Red Spot of the planet, floating in some kind of artificial anti-gravity field in the gaseous portion of the atmosphere—" and in some way worm from them the secret of their anti-gravity field, say, eminently suited to the task." He beamed at me. I looked around. They were all beaming. At me! Suddenly I smelled a rat as big as an elephant. That whole Kooleen 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.... when I already had more counts against me than a cur has fleas. Not Crude, but it was all I could squeeze out. I squeezed out more when I saw those pictures, though. Those inhabitants were charming, just charming if you like scorpions. Well, a cross between a scorpion and a grasshopper, to be accurate. Floating among that red stuff, they showed up a kind of sickly purple turning to gangrene around the edges. the great Casey Ritter, daredevil of the Solar System!" he sneered. 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 into a sea of ammonia among man-size scorpions just for the hell of it. Nuts! After all, in the pen a man can eat and breathe, and a guard won't reach in and nip off an arm or leg while he's got his back safe and secure in the grip of the good old Iron College, I relaxed. asteroid real estate racket. Pard Hoskins was his alias, and he had the tag of being a real slick operator. We swapped yarns for about a week when we met, and then I asked him what's his rap this trip. "Oh, a pretty good jolt if they can keep hold of me," he says. "I just His eyes watered at the memory, yearning like a hound-dog's over a fresh scent. I couldn't believe it. Those emeralds were in the inner shrine of the super-sacred, super-secret temple of the cavern-dwelling tribe of 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. 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 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 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, already penetrated the Great Red Spot of old Jupiter and come out that I could pry more information out of Pard Hoskins. Hoskins was in the bunch. He'd never get out of there, and he knew it. those scorpions, and how he'd made Akroida mad. "I put on a yeller slicker," he confessed sadly. "That there ammonia mist was eatin' into the finish on my spacesuit, so I draped this 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 drives them nuts! Thought they'd chaw me up and spit me out into the chlorine before I could get outa the damn thing. If my colorblind pal a-purpose to upset her." Then he winked at me. "But then I got off in a corner and cooked up some perfume that drives them nuts the other way sorta frantic with ecstasy, like the book says. Didn't have a chance to try it on Akroida, though. She wouldn't give me another audience. It's in the stuff they He ruminated a few minutes. "Tell you what, chump. Make them shell out with a green an' poiple spacesuit—them's the real Jupiter colors—an' put just a touch o' that there perfume on the outside of it. Akroida'll do anything fer you if she just gets a whiff. Just anything! But remember, don't use but a drop. It's real powerful." II slipped down onto the Red Desert of Mars and picked up the Killicut Ritter, compared with the value of the secret you are to buy with of emeralds back into its little safe. "Instead of sniping at me, why patted my pretty enameled suit, which was a study in paris green and passionate purple. I patted the three hundred pounds of arsenic crystals for Akroida and thing, and the temperature rose to nearly forty. Meanwhile the hopper-scorp reached the ship. Hastily I squirted some of my Scorpion-Come-Hither lure on the chest of my spacesuit, opened the lock, and popped out, brave as could be. Face to face with that thing, though, I nearly lost my grip on the handle. In fact, I'd have fainted intimate—or rather, the taps were. There was even a rather warm expression discernible in the thing's eyes, so I took heart and decided else. "I've never been here before, and so I've never met the charming lady," I informed him. "However, I have something very special in the way of jewels—not with me, naturally—and the rumor is that she might out thoughtfully, just like an ordinary business man, and I managed to tap out yes. He drifted closer close enough to get a whiff.... A shudder of ecstasy stiffened him. His head and eyes rolled with it, and he wafted closer still. Right there I began to harbor a premonition Hoskins. How had he made friends with the brute in the first place? natural lump on his back, and he darted away from me. I opened the throttle and tore after him among the immense red blobs that were now beginning to be patterned with dozens of green-and-purple scorpions, all busy filling huge baskets with buds and tendrils, no doubt. Other scorpions oared and floated about in twos and threes in a free and peaceable manner that almost made me forget that I was scared to persecutor was right, too. That anti-grav secret was worth more than block, skyscrapers and all. It was like a mammoth red cavern, and it glowed like the inside of a red light. No wonder those scorpions like green and purple. What a relief from all that red! A patch in the middle of the hall became a floating platform holding up a ten-ton cannon and twice as mean and dangerous. She was idly nipping shaking the jewels that were hung all over her repulsive carcass, and making the Halcyon Diamond on her chest blaze like a bonfire.
