This article examines the interrelation between stylistic and structural devices in criminal fiction. The study focuses on the role of authorial style in shaping the artistic effectiveness, readability, and long-lasting literary value of works devoted to crime, mystery, and justice. Before analyzing stylistic features in English and Uzbek criminal literature, the article discusses the concept of style, its etymology, theoretical definitions, and its manifestation in literary texts. Special attention is given to the idea that style is not merely an external decorative element but a fundamental artistic principle through which writers express their worldview, select events, construct characters, organize narrative details, and create suspense. The article also analyzes the works of such writers as Agatha Christie, Arthur Conan Doyle, Tohir Malik, O‘lmas Umarbekov, Charles Dickens, Komiljon Sindarov, and others. It argues that criminal fiction requires a particularly precise relationship between style and structure because details, clues, descriptions, dialogue, setting, and narrative rhythm all serve the process of revealing or concealing crime. The study concludes that in criminal fiction, an author’s individual style is manifested through language, character speech, creative method, selection of events, use of small details, and the manner of narration.
