The Maltese Falcon is a 1930 detective novel by American writer Dashiell Hammett, originally serialized in the magazine Black Mask beginning with the September 1929 issue. The story is told entirely in external third-person narrative; there is no description whatsoever of any character's thoughts or feelings, only what they say and do, and how they look. The novel has been adapted several times for the cinema. It is considered part of the hardboiled genre, which Hammett played a major part in popularizing.
Sam Spade is a private detective in San Francisco, in partnership with Miles Archer. The beautiful "Miss Wonderley" hires them to follow Floyd Thursby, who she claims has run off with her sister. Archer takes the first stint but is found shot dead that night. Thursby is also killed later and Spade is a suspect. The next morning, Spade coolly tells his office secretary, Effie Perine, to have the office door repainted to read simply "Samuel Spade".
