Crime fiction

Crime fiction is a catch-all term that encompasses short stories and novels involving crimes (frequently murders), puzzles, and/or adventures that almost always come to an emotionally satisfying conclusion; it is, however, a very broad term that covers many narrower genres or sub-genres such as "mystery stories", "detective stories", "suspense stories", "spy stories", "private eye stories", and "thrillers". There can be, moreover, broad overlap between these sub-categories within the same story. As with "science fiction", no single term has ever been coined to cover all these kinds of fiction that can satisfy the millions of aficionados of each types.
