The golden age of mystery fiction produced some of the most enduring characters in literary history. Sherlock Holmes, Father Brown, Hercule Poirot, and Inspector Alleyn remain household names more than a century after their creation. These iconic detectives — and the brilliant writers who invented them — built a genre defined by logic, atmosphere, and the deeply satisfying unravelling of a perfect crime.
