Old Man had that look of intense glee on his face that meant someone was in for a very rough time. Since we were alone, it took no great feat of intelligence to figure it would be me. I talked first, bold attack being the best defense and so forth. company secrets to me.” The grin was even wider now and he actually chortled as he thumbed a antagonistic toward future ancestral messengers. What He was telling me —the guy who did the job while he sat back on his fat paycheck in an air-conditioned office. like that at all. I have a fleet of expensive ships that are equipped to do almost anything—manned by a bunch of irresponsibles like you .” “How I wish I could fire you all! Combination space-jockeys, mechanics, engineers, soldiers, con-men and anything else it takes to do the repairs. I have to browbeat, bribe, blackmail and bulldoze you thugs into doing a simple job. If you think you’re fed up, just think I smiled, a little weakly, I’m afraid, as if I had never meant to keep that account a secret. His spies were getting more efficient every day. Walking down the hall, I tried to figure a way to transfer the money without his catching on—and knew at the same time he was figuring a way to outfigure me. It was all very depressing, so I stopped for a drink, then went on to fixed universe. 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 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 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 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. only locked inside a mountain of handmade stone, but I had managed to irritate the things who had built the pyramid. A great beginning for a job and one clearly designed to drive a stronger man than me to the bottle. Normally, a repairman stays away from native cultures. They are poison. Anthropologists may not mind being dissected for their science, but a repairman wants to make no sacrifices of any kind for his job. For this inaccessible place. fool-proof. I had a pryeye of my own construction. It looked like a piece of rock in the memory bank of the machine translator and had tagged a few expressions. This is fairly easy to do when you have a machine memory to work with. One of the lizards gargled at another one and the second one turned around. I tagged this expression with the phrase, “Hey, It gurgled out through the speaker in the local tongue and he turned around. When you get enough reference phrases like this in the memory bank, the MT brain takes over and starts filling in the missing pieces. As soon as figured it was time to make a contact. I found him easily enough. He was the Centaurian version of a goat-boy—he herded a particularly loathsome form of local life in the swamps outside the town. I had one of the working eyes dig a cave in pushed a switch and a handful of the local currency, wampum-type shells, rolled out of the cave and landed at his feet. had been out of touch with things since his death and Goat-boy happily filled him in. I learned all I needed to know of the history, past and recent, and it wasn’t nice. 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 distant continent. The idea that the race would develop and might reach this continent never occurred to the beacon mechanics. Which is, of course, what happened. 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 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 cheerfully rat on me when I got back. Diplomacy was called for. I sighed and dragged out the plastiflesh equipment. Working exactly like them, just something close, to soothe the native mind. It’s logical. If I were an ignorant aborigine of wearing a suit of plastiflesh that looked remotely humanoid, I would at 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 flying lizard, sort of a cardboard pterodactyl, and the slowly flapping wings obviously had nothing to do with our flight. But it was impressive enough for the natives. The first one that spotted me screamed and dropped over on his back. The others came running. They milled and just whispered loud enough for the throat mike to catch. This was jaws. The natives chomped and rattled and the translation rolled out almost Some of the more credulous natives prostrated themselves and others fled screaming. One doubtful type raised a spear, but no one else tried that after the pterodactyl-eye picked him up and dropped him in the swamp. The priests were a hard-headed lot and weren’t buying any lizards in a poke ancient reptile who clearly was one of the leaders. I waddled toward him “You are a liar! You are no ancestor of ours! We will—” “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 motion to cover my flicking a coin grenade toward them. It blew a nice hole in the floor with a great show of noise and smoke. The First Lizard knew I was talking sense then and immediately called a across the floor. There was a bolted and guarded door that led into the pyramid proper. While it was being opened, the First Lizard turned to me. “Undoubtedly you know of the rule,” he said. “Because He from constant polishing. I checked the readings carefully and found just what I had suspected. One of the eager lizards had managed to open a circuit box and had polished the switches inside. While doing this, he had thrown one of the switches and that had caused the trouble. Rather , that had repairs didn’t take long, though there was plenty of groaning from the blind lizards when they heard me ripping the wall open to get at the power leads. I even hooked a gadget to the water pipe so their Holy Waters would have the usual refreshing radioactivity when they they were waiting for. 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 The rest of their clan showed up at the foot of the stairs and made a in the water. “The ancestors are annoyed and have decided to Before they could get any more bright ideas, I threw the switch and my
