The five novels that Hammett published between 1929 and 1934, collected here in one volume, have become part of modern American culture, creating archetypal characters and establishing the ground rules and characteristic tone for a whole tradition of hardboiled writing. Drawing on his own experiences as a Pinkerton detective, Hammett gave a harshly realistic edge to novels that were at the same time infused with a spirit of romantic adventure. His lean and deliberately simplified prose won admiration from such contemporaries as Gertrude Stein, Ernest Hemingway, and William Faulkner.

Each novel is distinct in mood and structure. Red Harvest (1929) epitomizes the violence and momentum of his Black Mask stories about the anonymous detective the Continental Op. In this raucous and nightmarish evocation of political corruption and gang warfare in a western mining town (modeled on Butte, Montana) nicknamed "Poisonville," the Op takes Machiavellian pleasure in pitting one faction against another to bring about their mutual destruction. The Op returns in The Dain Curse (1929) to preside over a more ornately melodramatic tale involving jewel theft, drugs, and a mysterious religious cult. With The Maltese Falcon (1930) and its protagonist Sam Spade, Hammett achieved his most enduring popular success. A tightly constructed quest story with an unforgettable cast of eccentric adventurers, it is at the same time shot through with a sense of disillusionment and the arbitrariness of personal destiny.

The Glass Key (1931), an exploration of city politics at their most scurrilous, tracing intricate patterns of loyalty and betrayal in scenes charged with drama. His last novel, The Thin Man (1934), is a ruefully comic tale distinct from the rest of his work. Paying homage to the traditional mystery form, it is best remembered for its protagonists Nick and Nora Charles, the sophisticated inebriates who would enjoy a long afterlife in the movies.

Hammett's years of experience as a Pinkerton detective give even his most outlandishly plotted mysteries a gritty credibility. Mixing melodramatic panache and poker-faced comedy, his stories are hard-edged entertainment for an era of headlong change and extravagant violence, tracking the devious, nearly nihilistic exploits of con men and blackmailers, slumming socialites and deadpan assassins. As guide through this underworld he created the Continental Op, the nameless and deliberately unheroic detective separated from the brutality and corruption around him only by his professionalism.
