Tarrano the Conqueror-Ray Cummings

What they desperately require is an element of unpredictability, and that’s precisely what they get when Thomas Cole, a man from the past, is inadvertently thrust into their time. Can he disrupt their calculated predictions, or is he merely another variable in a game of chance? Discover the thrilling tale of The Variable Man, originally published in the September 1953 issue of Space Science Fiction magazine. (Summary by Gregg Margarite)
