<passage>:
Grannie Annie, who wrote science fiction 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. Grannie Annie! planted firmly on the varpla carpet and her wrinkled face was set in calm defiance. I barged across the lounge and seized her hand. "Grannie Annie! I haven't seen you in two years." "Hi, Billy-boy," she greeted calmly. "Will you please tell this 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 But to me she was still Grannie Annie, as old-fashioned as last year's Pistols and it wasn't Ganymede As we strode down the aisle a mangy-looking Venusian began to pound a tinpan piano in the pit. Grannie Annie pushed me into a seat in the front row. 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." From the left wing Grannie Annie appeared. She bowed and took her place Doctor Universe nodded and turned to Grannie Annie who had raised her It grew a little tiresome after a while and I wondered why Grannie had snipped the Martian's single lock of hair. A booted foot bludgeoned into his mouth. Moments later an official hydrocar roared up and a dozen I.P. men 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 In a booth well toward the rear the old lady surveyed me with sober eyes. "Billy-boy, did you see the way that crowd acted?" I nodded. "As disgraceful an exhibition as I've ever seen. The I.P. men 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. "What do you mean?" develops into a sense of impotence and a desire for leadership or followed." Grannie Annie lit a cigarette and flipped the match to the floor. 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 Grannie nodded. "Yes," she said. "That's exactly what I think." 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. "Let's get out of here," I said, getting up. Zinnng-whack! fresco seemed to melt away suddenly. A heat ray! Grannie Annie leaped to her feet, grasped my arm and raced for the door. Outside a driverless hydrocar stood with idling motors. The old woman threw herself into the control seat, yanked me in after her and threw over the starting stud. An instant later we were plunging through the dark night. We had traveled this far by ganet , the tough little two headed pack animal of the Venus hinterland. Any form of plane or rocket would have had its motor instantly destroyed, of course, by the magnetic force belt that encircled the planet's equator. Now our drivers changed to boatmen, and we loaded our supplies into three clumsy 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. Grannie's incredible story? Or was this another of her fantastic plots undulating sweeps toward the center of the camp. Fascinated, I watched it advance and retreat, saw two hyalescent eyes swim out of the murk. It charged, and with but a split second to act, I threw myself flat. There was a rush of mighty wings as the thing swept over me. Sharp talons raked my clothing. Again it came, and again I rolled swiftly, missing the thing by the narrowest of margins. From the tent opposite a gaunt figure clad in a familiar dress appeared. Grannie gave a single warning: "Stand still!" 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. I stood frozen as the diminuendo of its wild cries echoed back to me. "In heaven's name, what was it?" "Then that would mean...?" "That it was sent by our enemy, the same enemy that shot at us in the cafe in Swamp City. Exactly." Grannie Annie halted at the door of her tent and faced me with earnest eyes. "Billy-boy, our every move is being watched. From now on it's the survival of the fittest." The following day was our seventh in the swamp. The water here 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 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. that's manifested by laughing. But just what it is that makes them laugh, I don't know." Food supplies and fresh drinking water were replenished at the hut. Several mold guns were borrowed from the prospector's supply to arm the Grannie frowned in annoyance, but the prospector was adamant. He 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. advance on foot. It was Karn who first sighted the ship. Striding in the lead, he suddenly halted at the top of a hill and leveled his arm before him. suspended between them was a network of copper wire studded with white insulators. Grannie gazed a long moment through binoculars. "Billy-boy, take three Venusians and head across the knoll," she ordered. "Ezra and I will circle in from the west. Fire a gun if you strike trouble." But we found no trouble. The scene before us lay steeped in silence. Mid-way we could see a circular hatch-like door. "Up we go, Billy-boy." Heat gun in readiness, Grannie Annie began to climb slowly. The silence remained absolute. We reached the door and pulled it open. plate and their radiations stepped up by an electro-phosicalic process." Karn raised the butt of his pistol and brought it crashing against the glass wall. His arm jumped in recoil, but the glass remained intact. "You'll never do it that way," Grannie said. "Nothing short of an atomic blast will shatter that wall. It explains why there are no guards here. The mechanism is entirely self-operating. Let's see if the Grannie stamped her foot. "It's maddening," she said. "Here we are at
