GRANDMA PERKINS AND THE SPACE PIRATES smoke-and-flame eyes kindled sparks in hearts all over the universe. But it took sweet old Grandma Perkins, of the pirate ship Dirty to set the Jupiter moons on fire . smile. The two of them were sitting in the finest lounge of the luxury space ship Kismet was blasting through space at close to the speed of light, bound from Callisto, one of Jupiter's moons, back to Earth. But none of the two hundred Earthbound passengers were conscious of the speed at all. Darling Toujours waved a long cigarette holder at the author. "Don't Carlton asked. The solar system's most famous actress clamped her scarlet lips shut with rage. It would take someone like Carlton E. perfect body—her slightly over-sized mouth. She began to wish that she had never left Callisto, that she had cancelled her passage on the Kismet when she learned that Carlton was to be a fellow passenger. But her studio had wired her to return to Earth immediately to make a new series of three dimensional video films. And the Kismet was the only first class space ship flying to away from Mrs. Perkins and rudely propelled the older woman out the and read, but her cabin was so small that there was no room for any other furniture besides the bed. He stretched his long arms up to bring down the heavy bag and found himself wondering just how it had gotten up there in the first place. He didn't remember ever putting it there for her and Grandma Perkins guaranteed to pay them so much for the flight, which you've already done, and they guaranteed that you wouldn't be put off against your will until you reached your destination." "But why do we have to have a contract?" Johnny leaned back, relaxing against the door. "Well, STAR—that's Stellar Transportation and Atomic Research, you know—is one of Thirteen," we call them. STAR charters every space flight in this neck of the woods. Well, back in the old days, when space flights were scarce, it used to be that you'd pay for a ticket from Saturn to Earth, say, and you'd get to Mars and they'd stop for fuel. Maybe somebody on Mars would offer a lot of money for your cabin. So STAR would just bump you off, refund part of your money and leave you stranded there. In order to get the monopoly, they had to promise to stop all that. And got around to her little cranny most of it was cold. But she didn't complain. She enjoyed watching the people with the more expensive from her little table over to one of the very comfortable sofas in the main lounge. In reality she wasn't supposed to be sitting there, but she hoped that she could get away with it. The divans were so much more comfortable than her hard, narrow bed that she felt like sitting there for a long time, by herself, just thinking. But her hopes met with disappointment. For shortly after she sat down, but loudly enough for Grandma Perkins to hear. to. But any time I want to get rid of somebody I just offer to show them pictures of my family. You'd be surprised how effective it is." Johnny laughed. "Why are you going to Earth, anyway, Grandma?" The old woman sighed. "It's a long story, Johnny, but you just sit down and I'll tell it to you." remembering the heavy box in her cabin that got moved up and down without his help, suppressed a smile on the word "feeble." "There aren't many friends my age left around any more. So I'm being sent to Earth to a home full of dear, sweet old ladies my age, the money for which is being provided by my dear, sweet children—all ten of them." Grandma dabbed a bit of a handkerchief at her eyes. "The Grandma Perkins never finished the sentence, for interrupting her came excitement after all. At the door to the steps leading to her downstairs cabin she paused to think. "If I go down and hide, I'll miss all the fun. Of course, it's safer, and an old woman like me shouldn't be up and about when pirates are around, but—" A delicious smile spread over her face as she took her scruples firmly in hand and turned to follow the bellowing Captain The Starship Kismet was the pride and joy of Stellar Transportation and Atomic Research. It was outfitted with every known safety device "What in great space has happened to the motors? Why are we losing speed?" "Pirates going to board us. How nice," muttered Grandma to herself as on board my ship," the Captain shouted to the Communications Officer. "Oh, my goodness. That doesn't sound very smart," Grandma said half aloud. And turning from the doorway, she crept back through the deserted passageway. The main passenger hatch was not too far from the bridge. Grandma found it with ease, and in less than three minutes she had zipped herself into one of the emergency-use space suits stowed away beside the port. She felt awfully awkward climbing into the monstrous steel and plastic contraption, and her small body didn't quite fit the proportions of the metallic covering. But once she had maneuvered herself into it, she felt quite at ease. "Pirates! I'm hiding from the pirates. They'll never find me here!" she "That's the one, boys," said another voice. "Let's go." Catching hold of Grandma's arm, they led her out into the emptiness of free space. Half an hour later, after the pirate ship had blasted far enough away from the "That's better. And now, Miss Toujours, maybe you'd be more comfortable without that space suit on," he said. attire." As the men approached her, Grandma sensed the game was up. "Okay," she told them. "I give up. I can make it by myself." She started to take the bulky covering off. She had gotten no more than the headpiece off when the truth dawned on her companions. overheard that you intended to board the Kismet , searching for only one person, I decided that one person had to be Darling Toujours. I guessed right off that she was the only one on board worth kidnapping "You never would have gotten inside the Kismet without my assistance. And even if you had, you'd never have gotten back out alive. Grandma Perkins paused in her narrative and looked up at her audience, giving them a withered little smile. "And if you want to know why, well ... I was bored on the Kismet , and I thought how nice it would be to run away and join a gang of cutthroat pirates." "She's batty," moaned Snake. "She's lost her marbles," muttered another. "Let's toss her overboard right now," said still another. Lamps O'Toole took the floor. "Now, wait a minute. We can't do that," control seats and lit a cigarette. "So, when us good, honest men couldn't find any work because of STAR, and we didn't want to give up working in space, we just ups and decides to become pirates. This was our first job, and we sure did need the money we could have gotten out of Darling Toujours' studios for ransom." money, and to top it all off, we'll be wanted for piracy by the Space Patrol." back?" suggested Snake hopefully. "I haven't got any rich relatives period," she said pertly. Then she you promised you wouldn't bring me back at all." "I figured as much," Lamps said dolefully. "Lookit, Grandma, the best thing we can do is to put you off safely at the next place we stop. Unless we get you back in one piece the Space Patrol will be on our necks forever. So don't go getting any ideas about joining up with us." "Well, the very least you could do for a poor old lady is to feed her,"
