Lester del Rey was surely one of science fiction's most happily argumentative representatives, an authority on a variety of subjects far too wide to list, and with a command of language, agility of mind, and the total confidence to pass as an authority on any subject.

In an odd way, this is what science fiction is all about-the ability to convince the reader, or the listener, of the absolute reality of total impossibilities. But of course, one needs more than gall, a good mind, and command of the langugae. One needs talent, and professionalism, and experience-three qualities that add up to the controlled power which is the key to the finest of Lester del Rey's writing.

Of which these five stories from the Golden Age of Science Fiction are a prime example: "Vengeance is Mine," "Superstition," "Life Watch," "For I Am a Jealous People," and "Pursuit."
