A "Whodunit" is a genre of fiction that revolves around a mysterious crime, typically a murder, where the identity of the perpetrator is unknown. The narrative often follows a detective or amateur sleuth as they gather clues, interview suspects, and piece together evidence to solve the case. This genre engages readers by inviting them to solve the mystery alongside the protagonist. Classic examples of Whodunits include works by authors like Agatha Christie and Arthur Conan Doyle, featuring iconic characters such as Hercule Poirot and Sherlock Holmes.
