of course, but I knew it had arrived when the grapples in the claws latched onto the steel plates on my shoulders. One: The beacon was repaired. Two: The door was sealed, so there should be no more sabotage, accidental or deliberate. I leaned out quickly, grabbed it and threw it into the air with a single motion. Before it could fall, I had my Solar out and, with a wide-angle antagonistic toward future ancestral messengers. I stripped off my tattered lizard suit back in the ship, very glad that it would be some other repairman who’d get the job. 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 I have a little job I know you’ll enjoy. Repair job. The Centauri beacon has shut down. It’s a Mark III beacon.…” “ “I never heard of it either until Records dug up the specs. They found them buried in the back of their oldest warehouse. This was the earliest type of beacon ever built—by Earth, no less. Considering its location on one of the Proxima Centauri planets, it might very well “This department is officially called Maintenance and Repair, when it really should be called trouble-shooting. Hyperspace beacons are made to last forever—or damn close to it. When one of them breaks down, it is never the spaceport. By that in this non -space the regular rules don’t apply. Speed and The first ships to enter hyperspace had no place to go—and no way to even tell if they had moved. The beacons solved that problem and opened the entire universe. They are built on planets and generate 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? Not through hyperspace. All you can do is approach as close as you can by using other beacons, then finish the trip in normal space. This can take months, and often does. a built-in safety factor I never could eliminate from the machine. I would much rather take a chance of breaking through near some star than spend time just barreling through normal space, but apparently Tech knows this, too. They had a safety factor built into the computer so you couldn’t end up inside a star no matter how hard you tried. I’m sure there was no humaneness in this decision. They just this, with some oil painting and free-fall workouts in the gym, passed the time. I was asleep when the alarm went off that announced planetary distance. outside the atmosphere, I sent a flying eye down to look things over. In this business, you learn early when and where to risk your own skin. The The old boys had enough brains to choose a traceable site for the The image blinked, focused—and a great damn pyramid swam into in a ten-mile circle was this pyramid—and that definitely I dived the eye lower. The pyramid was a crude-looking thing of pyramid was a hollow basin filled with water. When I saw that, something basin on top of it for water this was used to cool the reactor that powered the monstrosity. If the water was still there, the beacon was still there—inside the pyramid. The natives, who, of course, weren’t even mentioned by the idiots who constructed the thing, 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 irritate the things who had built the pyramid. A great beginning for a Normally, a repairman stays away from native cultures. They are poison. reason, most beacons are built on uninhabited planets. If a beacon has to go on a planet with a culture, it is usually built in some inaccessible place. Why this beacon had been built within reach of the local claws, I had yet to find out. But that would come in time. The first thing to do was fool-proof. I had a pryeye of my own construction. It looked like a piece of rock town about a thousand kilometers from the pyramid and dropped the eye. the swamps outside the town. I had one of the working eyes dig a cave in In addition to the pyramid being around the beacon, there was a nice little religious war going on around the pyramid. It all began with the land bridge. Apparently the local lizards had been living in the swamps when the beacon was built, but the builders religion. A shiny metal temple out of which poured a constant stream of magic water—the reactor-cooling water pumped down from the atmosphere condenser on the roof. The radioactivity in the water didn’t hurt the natives. It caused mutations that bred true. A city was built around the temple and, through the centuries, the pyramid was put up around the beacon. A special branch of the priesthood served the temple. All went well until one of the priests violated the murder and destruction since then. But still the holy waters would not flow. Now armed mobs fought around the temple each day and a new band of priests guarded the sacred fount. And I had to walk into the middle of that mess and repair the thing. 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 “native life-forms” were quite well protected. There were spy cells on my ship, all of which I hadn’t found, that would cheerfully rat on me when I got back. least stay and talk to him. This was what I was aiming to do with 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 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 That night I took the ship down into the hills nearest the pyramid, an the plaza fronting the temple. The priesthood arrived. Some of the more credulous natives prostrated themselves and others fled temple was a small one built against the base of the pyramid. I wasn’t stopped, so it looked all right. The temple was a single “Stop!” I thundered before he got so far in that he couldn’t back out. “I said your ancestors sent me as emissary—I am not one of your ancestors. Do not try to harm me or the wrath of those who have Passed On will turn against you.” meeting of the shamans. It, of course, took place in the public bathtub pyramid proper. While it was being opened, the First Lizard turned to MARK III BEACON—AUTHORIZED PERSONNEL ONLY . The trusting builders counted on the sign to do the in the reactor. they were loaded in a metal crate. In the darkest hour before dawn, the heavy-duty eye dropped the crate outside the temple and darted away without being seen. at the power leads. I even hooked a gadget to the water pipe so their the dry pipe. Then a roar came from outside the pyramid that must have 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 ancestors!” I had the speaker on full volume and the vibration almost shook my head off. The rest of their clan showed up at the foot of the stairs and made a forbid entrance to the Inner Temple forever though, out of kindness,
