A "whodunit" is a type of mystery story where the main focus is on solving a crime, usually a murder. The plot revolves around a detective or amateur sleuth who gathers clues and interviews suspects to uncover the identity of the culprit. The suspense builds as readers are invited to piece together the evidence alongside the characters, making it an engaging experience. These stories often feature a cast of characters, each with their own motives and secrets. Classic examples of whodunits include works by authors like Agatha Christie and Arthur Conan Doyle, where the twists and turns keep readers guessing until the very end.
