Mystery

Mysteries are also very widely read by SF fans (and not so much by fantasy fans). I think there are two ways in which SF and mysteries are alike. First, they're constrained by logic and certain real-world limits. Second, they give the author the opportunity to investigate a new and unfamiliar piece of culture (the detective is often working outside his normal milieu).
