James M. Cain's first novel, The Postman Always Rings Twice, is the noir novel that paved the way for all the noir fiction that followed. Frank Chambers, a drifter, is dropped from the back of a truck at a rundown rural diner. When he spots Cora, the owner's wife, he instantly decides to stay. The sexy young woman, married to Nick, a violent and thuggish boor, is equally attracted to the younger man and sees him as her way out of her hopeless, boring life. They begin a clandestine affair and plot to kill Nick, beginning their own journey toward destruction.
