<passage>:
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 hair-raising than any she had ever concocted. And the danger from the villain of the piece didn't worry her—I was the guy he was shooting at.

"Beg pardon, thir," he said with his racial lisp, "thereth thome one to thee you in the main lounge." His eyes rolled as he added, "A lady!" was a sanctuary, a rest club where in-coming pilots and crewmen could relax before leaving for another voyage. The rule that no females could pass its portals was strictly enforced. Grannie Annie! tied by a ribbon under her chin. Her high-topped button shoes were planted firmly on the varpla carpet and her wrinkled face was set in I barged across the lounge and seized her hand. "Grannie Annie! I friend of yourth, you'll have to take her away. It'th abtholutely againth the ruleth...." and Grannie Annie her usual whisky sour—I waited until she had tossed ? What happened to the book you were writing?" "Hold it, Billy-boy." Laughingly she threw up both hands. "Sure, I knew 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 rolled herself a cigarette. "It wasn't ." 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 somewhere and talk." She minced lightly down the aisle, climbed the stage steps and disappeared in the wings. "That damned fossilized dynamo," I muttered. "She'll be the death of me yet." subsided, the man continued: "As most of you are familiar with our program, it will be unnecessary . "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 tracto-car." And so it went. Questions from Mars, from Earth, from Saturn flowed in It grew a little tiresome after a while and I wondered why Grannie had brought me here. And then I began to notice things. dragging his cumbersome third leg behind him. Kagors, of course, had an unpleasant history of persecution since the early colonization days of rushed out and scattered the crowd. But a few stragglers lingered to shout derisive epithets. Grannie Annie came out from behind the box office then. She took my arm ought to clamp down." "The I.P. men aren't strong enough." She said it quietly, but there was a glitter in her eyes and a harsh line about her usually smiling lips. then she leaned back, 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. intolerance. The Green Flames might be said to be an inorganic opiate, a thousand times more subtle and more powerful than any known drug." I was sitting up now, hanging on to the woman's every word. Grannie Annie lit a cigarette and flipped the match to the floor. If Grannie expected me to show surprise at that, she was disappointed. "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." and laughed heartily. "The same old Flowers," I said. "Tell me, who's She regarded me evenly. "What makes you say that?" I shrugged. times more potent and is transmiting it en masse ." If it had been anyone but Grannie Annie there before me, I would have called her a fool. And then all at once I got an odd feeling of approaching danger. 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 Grannie's incredible story? Or was this another of her fantastic plots appeared. Grannie gave a single warning: Grannie Annie fired with deliberate speed. "Hunter-bird," Grannie said calmly. "A form of avian life found here and follows with a relentless purpose." "Then that would mean...?" jetty, and Grannie Annie was introducing me to Ezra Karn. 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 "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 because I was alone, and they didn't notice me, and Darthier escaped because he made 'em laugh." "Laugh?" A scowl crossed Grannie's face. about us in hordes. The next day an indefinable wave of weariness and despondency beset our entire party. I caught myself musing over the futility of the venture. Only the pleadings of Grannie Annie kept me from turning back. On the morrow I realized the truth in her warning, that all of us had been exposed to the insidious radiations. Grannie gazed a long moment through binoculars. "Billy-boy, take three "Up we go, Billy-boy." Heat gun in readiness, Grannie Annie began to There was no sign of life. "Somebody's gone to a lot of trouble here," Ezra Karn observed. Somebody had. Before us stretched a narrow corridor, flanked on the Grannie stamped her foot. "It's maddening," she said.
