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 and after awhile I braced him. I was right. I'd met the shrimp before when I was wound up in an 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, no!" I moaned. "What were you trying to do, start a feud between us and Mars?" He shrugged, but his little black-currant eyes began to sparkle with 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 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 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. friendly as a bottle of strychnine. But for a lad headed for Jupiter 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 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 put just a touch o' that there perfume on the outside of it. Akroida'll tiny bottle like that boy Aladdin clutching his little old lamp. I'd had a lot of cooperation getting that far. An Earth patrol had slipped down onto the Red Desert of Mars and picked up the Killicut 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 Ritter, compared with the value of the secret you are to buy with 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 don't you get that brain busy and set our rendezvous?" 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 was as nervous as a cat with new kittens. Feeling again for my little bottle of horrid stench, I breathed a prayer to the god of idiots and I braced up and tapped out the greeting Pard had taught me. My 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 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 I tried to back off from him a bit, but the ship stopped me. "I'm Casey Ritter. What's your label, chum?" "Attaboy," he ticked coyly. "Attaboy?" Things blurred around me. It couldn't be. It was just plain nuts. Then I got a glimmer through my paralyzed gray matter. "Who named you that?" He simpered. "My dear friend, Pard Hoskins." 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 mad at him? Don't you hate yellow, too?" He hung his silly head. "I fear I am colorblind," he confessed sadly. Right there I forgave him for pulling that eye on me. He was the guide I needed, the one who had got Pard out alive. I almost hugged him. in my boat." Well, I'd met the first of the brood and was still alive. Not only alive but loved and cherished, thanks to Pard's inventiveness and to a kindly fate which had sent Pard's old pal my way. A great man, Pard Hoskins. How had he made friends with the brute in the first place? as solid as if on a floor. Which was fine for flying hopper-scorps, but what about Casey Ritter, who hadn't cultivated even a feather? Attaboy, however, had the answers for everything. Towing me from the airlock to the window ledge, he again sniffed that delectable odor on my chest, caressed me with his front pair of legs while I manfully shaking the jewels that were hung all over her repulsive carcass, and making the Halcyon Diamond on her chest blaze like a bonfire. Attaboy dumped me onto a floating cushion where I lay clutching and shuddering away from her and from the void all around me, and went across to her alone with the arsenic. over, ducked his head humbly half-a-dozen times, and pushed the box over beside her. Akroida eased her eyeball back, opened the box and sniffed, and then turned to Attaboy with a full-blown Satanic grin. I could hear her question reverberate away over where I was. "Who from?" asked Akroida. That conversation was telegraphed to me blow by blow by the actions of those hopper-scorps. I didn't need their particular brand of Morse Code at all. "Who from?" Attaboy cringed lower and blushed a purple all-over blush. "Dear lady, it is from an interspace trader who possesses some truly remarkable jewels," he confessed coyly. his code, she reared up higher on her skinny elbow and glared in my direction. "Casey Ritter? Never heard of him. Where's he from?" Well, after all, she wasn't blind. He had to confess. "I—uh—the A sort of jerking quiver ran through Akroida. She reared up even higher. Her mean Roman nose twitched. "An earthman? Like Pard Hoskins?" Attaboy shrank smaller and smaller. He could only nod dumbly. The storm broke, all right. That old dame let out a scream like a
