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 Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Grannie Annie! 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 But to me she was still Grannie Annie, as old-fashioned as last year's in the name of science fiction than anyone alive. But the public loved it. They ate up her stories, and they clamored for She was the most completely delightful crackpot I had ever known. "What happened to rolled herself a cigarette. "It wasn't Guns ." 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 "That damned fossilized dynamo," I muttered. "She'll be the death of me yet." These questions, my nine experts will endeavor to answer. For every question missed, the sender will receive a check for one thousand From the left wing Grannie Annie appeared.

The old woman paused. "Did you ever hear of the Green Flames?" she asked abruptly. I shook my head. "Some new kind of ..." "It's not a new kind of anything. The Green Flame is a radio-active rock once found on Mercury. The Alpha "When any form of life is exposed to these Gamma rays from the Green Flame rock, they produce in the creature's brain a certain lassitude and lack of energy. As the period of exposure increases, this condition develops into a sense of impotence and a desire for leadership or guidance. Occasionally, as with the weak-willed, there is a spirit of 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. enough to endanger all civilized life. "The archives tell us that one of the first acts of the overthrowing government was to cast out all Green Flames, two of which Vennox had ordered must be kept in each household. The effect on the people was immediate. Representative government, individual enterprise, freedom followed." Grannie Annie lit a cigarette and flipped the match to the floor. travels into the Varsoom district he had come upon the wreckage of an old space ship. The hold of that space ship was packed with Green Flames!" If Grannie expected me to show surprise at that, she was disappointed. I said, "So what?" "So everything, Billy-boy. Do you realize what such a thing would mean if it were true? Green Flames were supposedly destroyed on all planets after the Vennox regime crashed. If a quantity of the rock were in 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 representation be abolished on Jupiter. The time is ripe for a military dictator to step in. "And you can lay it all to the Green Flames. It seems incredible that a single shipload of the ore could effect such a wide ranged area, but in my opinion someone has found a means of making that quantity a thousand times more potent and is transmiting it en masse If it had been anyone but Grannie Annie there before me, I would 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 confidence for the first time since we had left Swamp City. "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 see, I'm positive the Green Flames have never been removed from the ship." Sleep had never bothered me, yet that night I lay awake for hours 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? Abruptly I stiffened. The familiar drone of the marsh was gone. In its appeared. Grannie gave a single warning: The thing in the darkness turned like a cam on a rod and drove at us again. This time the old woman's heat gun clicked, and a tracery of purple flame shot outward. A horrible soul-chilling scream rent the air. A moment later something huge and heavy scrabbled across the ground and shot aloft. Grannie Annie fired with deliberate speed. hand into one of those yellow streaks, he would have been devoured in a matter of seconds. The place was a two room affair, small but comfortable. The latest type of visi set in one corner showed that Karn was not isolated from Grannie Annie came to the point abruptly. When she had explained the object of our trip, the prospector became thoughtful. "Green Flames, eh?" he repeated slowly. "Well yes, I suppose I could find that space ship again. That is, if I wanted to." "What do you mean?" Grannie paused in the act of rolling herself a Karn shook his head. "They're a form of life that's never been seen by Earthmen. Strictly speaking, they're no more than a form of energy." "Laugh?" A scowl crossed Grannie's face. Grannie frowned in annoyance, but the prospector was adamant. He 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. "Up we go, Billy-boy."
