Use for novels and stories dealing with the detection and solution of crime. Where possible assign additional topical headings, e.g. a class-of-persons heading for the investigator, or a heading for the name of the investigator, and headings for the setting and for the crime involved.
Use for works whose prime purpose is to produce a feeling of frightened anticipation. These works may contain secondary elements, espionage, romance, or psychology.
