The "Hard-Boiled Detective" is a character archetype commonly found in crime fiction, particularly in the noir genre. These detectives are often tough, cynical, and morally ambiguous, navigating a gritty urban landscape filled with crime and corruption. They typically work outside the law, relying on their instincts and street smarts to solve cases. This character type emerged in the early 20th century, with notable examples including Sam Spade from Dashiell Hammett's "The Maltese Falcon" and Philip Marlowe from Raymond Chandler's works. Hard-boiled detectives often face personal struggles and complex relationships, adding depth to their stories.
