Crime fiction is one of the most popular literary genres and has been for more than a century. At the heart of almost all forms of mysteries—from the Golden Age puzzler to the contemporary police procedural, from American hardboiled fiction to the Japanese timetable mystery—is the investigator. He—or, increasingly, she—can be a private eye, a police officer, or a general busybody. But whatever forms these investigators take, they are the key element of crime fiction.
