The Maltese Falcon is a 1930 detective novel by Dashiell Hammett, originally serialized in the magazine Black Mask beginning with the September 1929 issue. The story has been adapted several times for the cinema. The main character, Sam Spade, appears in this novel and in three lesser-known short stories and is widely cited as the crystallizing figure in the development of the hard-boiled private detective genre. Raymond Chandler's character Philip Marlowe, for instance, was strongly influenced by Hammett's Spade. Spade was a departure from Hammett's nameless detective, The Continental Op. Spade combined several features of previous detectives, notably his cold detachment, keen eye for detail, unflinching, sometimes ruthless, determination to achieve his own form of justice, and a complete lack of sentimentality.
