Sam Spade
Sam Spade is a fictional character and the protagonist of Dashiell Hammett's 1930 novel The Maltese Falcon. Spade also appeared in four lesser-known short stories by Hammett. The Maltese Falcon, first published as a serial in the pulp magazine Black Mask, is the only full-length novel by Hammett in which Spade appears.
The character, however, is widely cited as a crystallizing figure in the development of hard-boiled private detective fictionโRaymond Chandler's Philip Marlowe, for instance, was strongly influenced by Spade. Spade was a departure from Hammett's nameless and less-than-glamorous detective, The Continental Op. Spade combined several features of previous detectives, most notably his detached demeanor, keen eye for detail, and unflinching determination to achieve his own justice.
