Frank Kane (1912–1968) was an American author best known for his prolific output of hardboiled detective fiction, particularly the long-running Johnny Liddell series. Born in Brooklyn, New York, Kane worked in journalism and radio before turning to fiction, bringing a sharp ear for dialogue and a feel for urban grit to his storytelling. Over his career, he penned more than forty novels and hundreds of short stories, many appearing in leading pulp magazines of the era. Kane's creation, Johnny Liddell, became a fixture of mid-century crime fiction—a tough, wisecracking private eye navigating a morally ambiguous underworld. Kane's work stood out for its snappy prose, fast-moving plots, and colorful gallery of gangsters, cops, and femme fatales. Though firmly rooted in the conventions of the noir tradition, his stories carried a distinct energy and personality, earning him a loyal readership and a lasting place in the history of American pulp literature.
