<passage>:
Grannie Annie, that waspish science-fiction writer, was in a jam again. What with red-spot Grannie Annie was the original research digger-upper, and when she laid the setting of a yarn on a star of the sixth magnitude, only a transportation-velocity of less than light could prevent her from visiting her "stage" in person. Antlers Park, the manager of I. V. himself. Antlers Park flicked the ash from his cheroot and shrugged. per second. The trouble is that by the time the average Martian reaches middle age, his ability to produce those vibrations steadily decreases. Then it was found that this ore, Acoustix, revitalized their sounding apparatus, and the rush was on." "What do you mean?" Park leaned back. "The rush to find more of the ore," he explained. . Chap by the name of Jimmy Baker runs that. However, the point is, between the properties of these two companies "What sort of trouble?" Grannie Annie had demanded. And when Antlers Detail for detail they were a duplicate of ourselves! "A mirage!" said Ezra Karn. "This is Jimmy Baker," she said. "He manages Larynx Incorporated , and he's the real reason we're here." I decided I liked Baker the moment I saw him. In his middle thirties, he was tall and lean, with pleasant blue eyes which even his sand goggles could not conceal. car's ability to move in any direction. "If I weren't a realist, I'd say that Larynx Incorporated has been bewitched," he began slowly. "We pay our men high wages and give them Jimmy Baker nodded. "The first symptoms are a tendency to garrulousness on the part of the patient. Then they disappear." He paused to make an adjustment of the windlass. Baker lit a cigarette. "There's all kinds of rumors," he replied, "but none of them will hold water. By the way, there's a cockatoo eyrie ahead of us." perched upon it. They watched us with their mild eyes as we passed, but Baker dropped his cigarette and ground his heel on it savagely. "Shaft Four, eh?" he repeated. "That's our principal mine. If the fever spreads there, I'm licked." "There must be ways of stopping this," she said. "Have you called in any physicians? Why don't you call an enforced vacation and send the men away until the plague has died down?" Baker shook his head. "Three doctors from Callisto were here last to produce during a period of thirty days or more, and you lose all rights." A visiphone bell sounded, and Baker walked across to the instrument. A man's face formed in the vision plate. Baker listened, said "Okay" and threw off the switch. Baker looked up. "That's right. We only began operations there a comparatively short time ago. Struck a rich vein of Acoustix that There was no refusing her. Jimmy Baker led the way down to a lower level where a huge laboratory and experimental shop ran the length neither would her millions of readers. Ezra Karn and I went back into the office. The old prospector chuckled. "Dang human dynamo. Got more energy than a runaway comet." were Jimmy Baker, Grannie, and Xartal. It was as if I were standing directly behind them. "It's Mr. Baker's own invention," the operator said. "An improvement on the visiphone." "Do you mean to say you can follow the movements of that car and its Antlers Park flashed on the screen. "A little. But up until yesterday the fever's been confined to the other side of the Baldric. We had one partial case, but my chemists gave the chap an antitoxin that seems to have worked. Come to think of it, I might drive over to Shaft Four and give Jimmy Baker the formula. I haven't been out in the Baldric for years, but if you didn't have any trouble, I shouldn't either." conversation. The view through the windscreen showed an irregular array of flagpole trees, with the sky dotted by high-flying cockatoos. "There's an eyrie over there," Jimmy Baker was saying. "We might as well camp beside it." Moments later a rude circle of flagpole trees loomed ahead. Across the drawing pictures on large pieces of pasteboard, and as I stood there in the visiscreen room, I watched him. There was no doubt about it, the Martian was clever. He would make a few rapid lines on one of the pasteboards, rub it a little to get likenesses of Ezra Karn, of myself, of Jimmy Baker, and of Antlers Park took form. plot. Look at that damned nosy bird! " and I saw the image of Jimmy Baker. The real Jimmy Baker stood next to Grannie, staring up at this incredible mirage. Grannie let out a whoop. "I've got it!" she said. "Those things we see up there are nothing more than mental images. made a greater impression on their brains," Grannie replied. Up on the eyrie a strange performance was taking place. The duplicate of Grannie Annie was bowing to the duplicate of Jimmy Baker, and the image of Ezra Karn was playing leap frog with the image of Antlers Park. part of the button appeared to be a powerful lens of some kind, and as I seized it and pulled it loose, I felt the hum of tiny clock work. All at once I had it! Red spot fever. Heat fever from the infra-red rays of Jupiter's great spot. Someone had constructed this lens to concentrate and amplify the power of those rays. The internal clockwork served a double purpose. It opened a shutter, and it rotated the lens slowly so that it played for a time on each of the sleeping men. controls was Antlers Park, the manager of Interstellar Voice. prim way next to Antlers Park. Park said: with a steady powerful pull to the connecting wire. Park's vehicle in his hand. There was a flash of purple flame, and a round hole appeared in our windscreen inches above Karn's head. "Heat gun!" Ezra yelled. Now we were rocketing over the sand dunes, winding in and out between the flagpole trees. I had to catch that car I told myself. Grannie but the triangular kite faltered. Taking advantage of Park's loss of speed, I raced alongside. The I. V. manager lifted his weapon frantically. But before he could "I see you've got Antlers Park. I'm glad of that. It saves me a lot of had been removed, and mounted on the hood was a large bullet-like contrivance that looked not unlike a search lamp. A blinding shaft of bluish radiance spewed from its open end. Playing it back and forth upon the marching men were Jimmy Baker and Xartal, the Martian. We drove slowly, keeping the line of marching Larynx miners always ahead of us. Jimmy Baker had struck a new big lode of Acoustix, a lode which if worked successfully would see Larynx Incorporated . Antlers Park For he knew that just as Jupiter's great spot was responsible for a climate and atmosphere suitable for an Earthman on this Eighth Moon, so also was that spot a deadly power in itself, capable when its rays were concentrated of causing a fatal sickness. Then suddenly becoming fearful of Grannie's prying, Antlers Park strove to head her off before she reached Shaft Four. He did head her off and managed to lure her and Baker and Xartal into the Shaft barracks where they would be exposed to the rays from the lens button. But Grannie only pretended to contract the plague. Park then attempted to outwit Ezra Karn and me by returning in Jimmy Baker's kite car with a cockatoo image of Grannie.
