The Repairman By Harry Harrison The 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. it would be some other repairman who’d get the job. — Harry Harrison What I had worked on every type or model made. But I had never heard of this found them buried in the back of their oldest warehouse. This was the He leaned back, wiped his hands on his handkerchief and gave me Lecture He was telling me —the guy who did the job while he sat back on his 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 figuring a way to outfigure me. It was all very depressing, so I stopped for a drink, then went on to By the time the ship was serviced, I had a course charted. The nearest To understand the importance of the beacons, you have to understand hyperspace. Not that many people do, but it is easy enough to understand to even tell if they had moved. The beacons solved that problem and when a beacon breaks down, how do you find it? the navigator, using every beacon I could get an accurate fix on. The computer gave me a course with an estimated point-of-arrival as well as comparison with its absolute magnitude showed its distance. Not as bad just about finished a correspondence course in nucleonics. Most distance. the ancient directions and finally located the right area. Staying this business, you learn early when and where to risk your own skin. The eye would be good enough for the preliminary survey. The old boys had enough brains to choose a traceable site for the beacon, equidistant on a line between two of the most prominent mountain 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, 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 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 reason, most beacons are built on uninhabited planets. If a beacon 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 make contact. To make contact, you have to know the local language. And, for that It swished down and landed at night in the bank of the local mud wallow. After about five of the local days, I had a sea of native conversation 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 caught one of them alone and shouted “Hey, George!” at him. 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 the MT could give a running translation of any conversation it heard, I 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 an outcropping of rock and wait for him. When he passed next day, I whispered into the mike: “Welcome, O Goat-boy Grandson! This is your grandfather’s spirit speaking from paradise.” This fitted in with what I could make out of the local religion. Goat-boy stopped as if he’d been shot. Before he could move, I pushed a switch and a handful of the local currency, wampum-type shells, rolled out of the cave and landed at his feet. “Here is some money from paradise, because you have been a good boy.” Not really from paradise—I had lifted it from the treasury the night before. “Come back tomorrow and we will talk some more,” I called after the fleeing figure. I was pleased to After that, Grandpa in paradise had many heart-to-heart talks with Grandson, who found the heavenly loot more than he could resist. Grandpa 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. 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 continent never occurred to the beacon mechanics. Which is, of didn’t hurt the natives. It caused mutations that bred true. A city was built around the temple and, through the centuries, the priests guarded the sacred fount. like them, just something close, to soothe the native mind. It’s logical. If I were an ignorant aborigine of enough for the natives. The first one that spotted me screamed and dropped over on his back. The others came running. They milled and the Great God,” I said. Of course I didn’t say it out loud, just whispered loud enough for the throat mike to catch. This was radioed back to the MT and the translation shot back to a speaker in my 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 they just stood and muttered. I had to take the offensive “I would talk with you, O noble priests,” I said. The The MT whispered into my ear, “Just what in the name of the thirteenth sin are you and what are you doing here?” I drew up my scaly figure in a noble gesture and pointed toward the ceiling. “I come from your ancestors to help you. I am here to restore the Holy Waters.” This raised a buzz of conversation behind me, but got no rise out of the “Stop!” I thundered before he got so far in that he couldn’t back out. “I said your ancestors sent me as The First Lizard knew I was talking sense then and immediately called a meeting of the shamans. It, of course, took place in the public bathtub and I had to join them there. We jawed and gurgled for about an hour and settled all the major points. I found out that they were new priests the previous ones had all been me. “Undoubtedly you know of the rule,” he said. “Because the old priests did pry and peer, it was ruled henceforth that only the He took a good thirty seconds to think it over and had to agree with me. The local torturer sniffled a bit and threw a little more charcoal on blueprints. With the faithful priests stumbling after me, I located the started The old boys had built well, I’ll give them credit for that. but slowly. The water-feed pipe from the roof, for example. The pipe they were loaded in a metal crate. In the darkest hour before dawn, the When they had given up, I boomed orders at them through a speaker in the The ancestors!” I had the speaker on full volume and the vibration The rest of their clan showed up at the foot of the stairs and made a they will let the waters flow.
