A FIRST WORDWhat the genre is for.
The detective story is the only literary form in which the reader is officially permitted to enjoy a corpse. Its central labour is to make the disordered legible: to take a death, a deception, or an absence, and reorganise the world around it until the reader sees what was always there.
The pleasure has two competing centres of gravity. One is the puzzle — Christie, Carr, Sayers — in which the body in the library is a chess problem and the detective is the smarter player. The other is the mood — Hammett, Chandler, Highsmith — in which the crime is symptomatic of a corrupted social world, and the detective walks through it because someone has to.
This deck holds both in view. It traces the form from Edgar Allan Poe in 1841 through the British Golden Age, the American hard-boiled school, the postwar procedural, Patricia Highsmith's psychological suspense, the Scandinavian and Japanese reinventions, and the recent literary thrillers. At the end is a list of thirty essential cases.
