The Unexpected Guest is a 1958 play by crime writer Agatha Christie. The play opened in the West End at the Duchess Theatre on 12 August 1958 after a previous try-out at the Bristol Hippodrome. It was directed by Hubert Gregg. Plot summary On a foggy night, Michael Starkwedder enters the home of the Warwicks through a window in the study. He finds the dead body of Richard Warwick, and finds Richard's wife, Laura, holding a gun that supposedly killed him. Michael does not believe she killed him, and she soon tells him she is innocent. The two decide to place the blame on an enemy from the past, MacGregor, a man whose son was killed when he was run over by Richard's car while Richard was driving drunk. As the story progresses, it is revealed that Laura was having an affair due to Richard's cruel nature, and was vouching for the man she was cheating with when she claimed to have killed Richard.
