Like Shaffer's most famous play, Sleuth, Whodunnit is a mystery. As the amusing title suggests, this is a comedic take, a parody. The eccentric cast of characters seems deliberately familiar (everyone you would expect at an English manor house), but no one is quite who they seem to be, and then there's the issue of a very inconvenient corpse. There's blackmail, seduction, the falsification of documents and more blackmail. "The fun is in the tricks the characters play on each other," says Sampson.
