Whodunnit
A mystery play in which the central question is the identity of a perpetrator—usually a murderer—with the audience following clues alongside the characters to solve the puzzle. The genre thrives on suspense, misdirection, and a satisfying reveal. Agatha Christie's The Mousetrap (the world's longest-running play, in London since 1952) and her The Unexpected Guest are classic theatrical whodunnits.
