Doctor Universe By CARL JACOBI Grannie Annie, who wrote science fiction under the nom de plume of Annabella C. Flowers, had stumbled onto a murderous plot more A woman here...! The Spacemen's was a sanctuary, a rest club where in-coming pilots and crewmen could relax before leaving for another Grannie Annie! I barged across the lounge and seized her hand. "Grannie Annie! I and Grannie Annie her usual whisky sour—I waited until she had tossed "What the devil are you doing on Venus? Don't you know women aren't allowed in the Spacemen's ? What happened to the book you were writing?" this place had some antiquated laws. Pure fiddle-faddle, that's what they are. Anyway, I've been thrown out of better places." She hadn't changed. To her publishers and her readers she might be Annabella C. Flowers, author of a long list of science fiction novels. But to me she was still Grannie Annie, as old-fashioned as last year's hat, as modern as an atomic motor. She had probably written more drivel in the name of science fiction than anyone alive. But the public loved it. They ate up her stories, and they clamored for more. Her annual income totaled into six figures, and her publishers sat back and massaged their digits, watching their earnings mount. One thing you had to admit about her books. They may have been dime novels, but they weren't synthetic. If Annabella C. Flowers wrote a novel, and the locale was the desert of Mars, she packed her carpet bag and hopped a liner for Craterville. If she cooked up a feud between two expeditions on Callisto, she went to Callisto. She was the most completely delightful crackpot I had ever known. "What happened to Grannie spilled a few shreds of Martian tobacco onto a paper and deftly ." I grinned. "All complete, I'll bet, with threats against the universe and beautiful Earth heroines dragged in by the hair." "What else is there in science fiction?" she demanded. "You can't have your hero fall in love with a bug-eyed monster." Up on the wall a clock chimed the hour. The old woman jerked to her . They don't go in for style in Swamp City. A theater to the grizzled colonials on this side of the planet meant a shack on stilts over the muck, DOCTOR UNIVERSE AND HIS NINE GENIUSES tinpan piano in the pit. Grannie Annie pushed me into a seat in the myself. I am Doctor Universe, and these are my nine experts." There was a roar of applause from the sets all over these planets listeners will appear and voice questions. These questions, my nine experts will endeavor to answer. For every . "One thing more. As usual we have with us a guest star who will match her wits with the experts. May I present that renowned writer of science fiction, Annabella C. Flowers." From the left wing Grannie Annie appeared. She bowed and took her place on the dais. Doctor Universe nodded and turned to Grannie Annie who had raised her "Charles Zanner in the year 2012. In a specially constructed tracto-car." And so it went. Questions from Mars, from Earth, from Saturn flowed in the visi sets. Isolated miners on Jupiter, dancers in swank Plutonian cafes strove to stump the experts. With Doctor Universe offering bantering side play, the experts gave their answers. When they failed, It grew a little tiresome after a while and I wondered why Grannie had Grannie Annie came out from behind the box office then. She took my arm closed her eyes, and I knew there was a story coming. "My last book, Death In The Atom she began. "When it was finished I had planned to take a six months' vacation, but those fool publishers of mine insisted I do a sequel. Well, I'd used Mars and Pluto and Ganymede as settings for novels, so for this one I decided on Venus. I went to Venus City, and I spent six weeks in-country. I got some swell background material, and I met Ezra Karn...." "Who?" I interrupted. "An old prospector who lives out in the deep marsh on the outskirts of Varsoom country. To make a long story short, I got him talking about his adventures, and he told me plenty." Grannie Annie lit a cigarette and flipped the match to the floor. If Grannie expected me to show surprise at that, she was disappointed. existence, and it fell into the wrong hands, there'd be trouble. "Of course, I regarded Karn's story as a wild dream, but it made corking good story material. I wrote it into a novel, and a week after it was completed, the manuscript was stolen from my study back on Earth." "I see," I said as she lapsed into silence. "And now you've come to the conclusion that the details of your story were true and that someone is attempting to put your plot into action." Grannie nodded. "Yes," she said. "That's exactly what I think." and laughed heartily. "The same old Flowers," I said. "Tell me, who's your thief ... Doctor Universe?" She regarded me evenly. "What makes you say that?" I shrugged. happening all over the System. There have been riots on Earth and Mars, police officials murdered on Pluto and a demand that government by en masse ." If it had been anyone but Grannie Annie there before me, I would appeared. On the booth wall a scant inch above Grannie's head the Grannie Annie leaped to her feet, grasped my arm and raced for the It was around the camp fire that night that Grannie took me into her "We're heading directly for Varsoom country," she said. "If we find Ezra Karn so much the better. If we don't, we follow his directions to the lost space ship. Our job is to find that ore and destroy it. You isolated crime there. But viewed from the perspective Grannie had tent. For some time I stood there, lost in thought. Could I believe Grannie's incredible story? Or was this another of her fantastic plots which she had skilfully blended into a novel? appeared. Grannie gave a single warning: Grannie Annie fired with deliberate speed. and follows with a relentless purpose." "Then that would mean...?" Grannie Annie came to the point abruptly. When she had explained the "What do you mean?" Grannie paused in the act of rolling herself a cigarette. "You know where it is, don't you?" "Ye-s," Karn nodded. "But like I told you before, that ship lies in Varsoom country, and that isn't exactly a summer vacation spot." Earthmen. Strictly speaking, they're no more than a form of energy." "Dangerous?" "Yes and no. Only man I ever heard of who escaped their country outside of myself was the explorer, Darthier, three years ago. I got away "Laugh?" A scowl crossed Grannie's face. "The Doctor Universe program," he said. "I ain't missed one in months. You gotta wait 'til I hear it." Grannie frowned in annoyance, but the prospector was adamant. He futility of the venture.
