The Postman Always Rings Twice

Cain’s title functions as a grim metaphor rather than a stand-alone aphorism: wrongdoing may seem to “get away with it” once, but consequences return—inescapably—for a second reckoning. In the hard-boiled, noir world Cain helped define, fate is not mystical so much as procedural and relentless: guilt, suspicion, and the law keep circling back. The phrase also suggests the illusion of control in passionate, impulsive lives; characters may think they can choose their moment, but the “postman” (news, justice, death, or truth) arrives on its own schedule. As a title, it primes readers for inevitability and repetition—crime followed by the return of accountability.
