In fog-bound San Francisco, private detective Sam Spade is hired by a mysterious woman who claims to be searching for her missing sister. The case curdles almost at once into murder, extortion, and double-dealing, drawing Spade into a tightening web of lies spun by elegant predators and desperate amateurs alike. At the center of their hunger is a legendary object-the Maltese Falcon-whose promise of immeasurable value turns every conversation into a negotiation and every gesture into a threat. Hard-boiled, swift, and morally serrated, Dashiell Hammett's novel defines noir's cold arithmetic: desire as motive, betrayal as method, and truth as whatever survives the next turn.
