The Repairman latched onto the steel plates on my shoulders. I had got turned around after the eye-burning and my flying beast hooked onto me backward. I had meant to sail out bravely, blind eyes facing Old Man had that look of intense glee on his face that meant someone The grin was even wider now and he actually chortled as he thumbed a eyes had been duly burned out, and they were back in business. Which “This is your contract,” he said. “It tells how and Four: The fact that they would probably let another repairman in, under one here.” He made a quick note on his secretary plate. “I have deducted 13 credits from your salary for the cost of the duplicate—as well as a 100-credit fine for firing a Solar inside a building.” I slumped, defeated, waiting for the blow to land. The Old Man fondled I have a little job I know you’ll enjoy. Repair job. The Centauri beacon has shut down. It’s a Mark III beacon.…” “ What “Mark III,” the Old Man repeated, practically chortling. I looked at the blueprints he handed me and felt my eyes glaze with horror. “It’s a monstrosity! It looks more like a distillery than a beacon—must be at least a few hundred meters high. The Old Man leaned over his desk, breathing into my face. “It He leaned back, wiped his hands on his handkerchief and gave me Lecture “This department is officially called Maintenance and Repair, when to last forever—or damn close to it. When one of them breaks down, He was telling He rambled on. “How I wish that were all it took! I would have a I nodded moodily at his pointing finger. his finger again. It was all very depressing, so I stopped for a drink, then went on to the spaceport. By tremendous amounts of power. This power is turned into radiation that is punched through into hyperspace. Every beacon has a code signal as part of its radiation and represents a measurable point in hyperspace. Triangulation and quadrature of the beacons works for navigation—only it follows its own rules. The rules are complex and variable, but they are still rules that a navigator can follow. when a beacon breaks down, how do you find it? by using other beacons, then finish the trip in normal space. This can take months, and often does. This job didn’t turn out to be quite that bad. I zeroed on the the stars, comparing them to the spectra of Proxima Centauri. It finally rang a bell and blinked a light. I peeped through the eyepiece. A fast reading with the photocell gave me the apparent magnitude and a comparison with its absolute magnitude showed its distance. Not as bad as I had thought—a six-week run, give or take a few days. After feeding a course tape into the robot pilot, I strapped into the acceleration tank and went to sleep. The time went fast. I rebuilt my camera for about the twentieth time and just about finished a correspondence course in nucleonics. Most repairmen take these courses. Besides their always coming in handy, the outside the atmosphere, I sent a flying eye down to look things over. In eye would be good enough for the preliminary survey. the first peak and kept it on a course directly toward the second. There was a nose and tail radar in the eye and I fed their signals into a scope as an amplitude curve. When the two peaks coincided, I spun the eye controls and dived the thing down. the beacon appear on the screen. The image blinked, focused—and a great damn pyramid swam into view. I cursed and wheeled the eye in circles, scanning the surrounding Locking the eye in a circular course, I dug through the Mark III plans—and there it was. The beacon had a precipitating field and a this was used to cool the reactor that powered the monstrosity. If the water was still there, the beacon was had built a nice heavy, thick stone pyramid around the beacon. I took another look at the screen and realized that I had locked the eye into a circular orbit about twenty feet above the pyramid. The summit of the stone pile was now covered with lizards of some type, apparently the local life-form. They had what looked like throwing sticks and arbalasts and were trying to shoot down the eye, a cloud of arrows and rocks flying in every direction. I pulled the eye straight up and away and threw in the control circuit that would return it automatically to the ship. , I had long before worked out a system that was fool-proof. I had a pryeye of my own construction. It looked like a piece of rock about a foot long. Once on the ground, it would never be noticed, though This was a favorite spot that drew a good crowd during the day. In the morning, when the first wallowers arrived, I flipped on the recorder. It gurgled out through the speaker in the local tongue and he turned When you get enough reference phrases like this in the memory bank, the figured it was time to make a contact. I found him easily enough. He was the Centaurian version of a Goat-boy Grandson! This is your grandfather’s spirit speaking from Grandson, who found the heavenly loot more than he could resist. Grandpa filled him in. It would have been easy enough if we were allowed a little mayhem. I could have had a lizard fry, fixed the beacon and taken off. Only equipment. Working from 3D snaps of Grandson, I modeled a passable reptile head over my own features. It was a little short in the jaw, me not having one of their toothy mandibles, but that was all right. I didn’t like them, just something close, to soothe the Centaurians. When the head was done, I peeled it off and attached it to an attractive suit of green plastic, complete with tail. I was really glad they had tails. The lizards didn’t wear clothes and I wanted to take along a lot of electronic equipment. I built the tail over a metal frame that anchored around my waist. Then I filled the frame with all the equipment I would need and began to wire the suit. When it was done, I tried it on in front of a full-length mirror. It was little before dawn, the eye hooked onto my shoulders and we sailed was light, then dropped straight down. It must have been a grand sight. The eye was camouflaged to look like a flying lizard, sort of a cardboard pterodactyl, and the slowly flapping wings obviously had nothing to do with our flight. But it was impressive the Great God,” I said. Of course I didn’t say it out loud, jaws. “Begone, O faithful steed,” I said to the eye, and pressed and he gave me a cold and fishy eye, then growled something. The MT whispered into my ear, “Just what in the name of the This raised a buzz of conversation behind me, but got no rise out of the will—” blind could enter the Holy of Holies.” I’d swear he was old suitcase can be called smiling. toward me. He was just drawing a bead on my right eyeball when my brain “Of course,” I said, “blinding is only right. But in the Holy of Holies, not now. I need my eyes to see and mend the Fount of Holy Waters. Once the iron.” behind me and I was alone in the dark. eye-sockets red pits of burned flesh. They knew what I wanted and led about a tenth the size of the ancient bucket of bolts and produced at least four times the power. Before I sent for it, I checked over the rest of the beacon. In 2000 years, there should be some sign of wear. heavy-duty eye dropped the crate outside the temple and darted away they were waiting for. for the eye-burning ceremony. A delightful prospect, eternity spent in a locked beacon with three blind lizards. In spite of their hospitality, I couldn’t accept. “What—you dare interfere with the messenger of your eye-sockets and the plastic gave off an authentic odor.
