Detective stories are a genre of fiction that focus on the investigation of a crime, often involving a detective as the main character. These stories typically present a mystery that needs to be solved, usually involving a murder or theft. The detective gathers clues, interviews suspects, and pieces together information to uncover the truth. The appeal of detective stories lies in their suspenseful plots and the challenge of solving the mystery alongside the protagonist. Famous examples include works featuring Sherlock Holmes by Arthur Conan Doyle and Hercule Poirot by Agatha Christie, both of whom have become iconic figures in this genre.
