In this collection of original essays, several prominent writers and critics of the genre examine the interface of theology and detection. Edward D. Hoch discusses Roman Catholic sleuths; James Yaffe discusses Jews in detective fiction; Marvin Lachman discusses the use of religious cults as mystery story backgrounds; co-editor Breen writes of Protestant religious mysteries and on Mormonism in the mystery; and four authors of mysteries about religious detectives—William X. Kienzle, Ellis Peters, Harry Kemelman, and Sister Carol Anne O'Marie—respond to a series of questions about their work.
