An experimental psychologist answers a two-sentence classified ad in "a weekly magazine of refined opinion." The result is Last Night at the Brain Thieves Ball…. This clever, comic story … is that kind of insightful science fiction that publishers hope won't get pigeonholed and critics pretend is not part of the genre. The obvious comparison for Spencer is Kurt Vonnegut; although their styles differ both writers deftly mix comedy, social comment and science fiction. But read Spencer for himself; within a few years we may be comparing other writers to him.
