WHAT IS IT ABOUT?
Opened at the Duchess Theatre in London on 23 March 1960. Does the letter given to Carla by the family solicitor hold the answer to her mother Caroline's death in prison, after being incarcerated for the murder of her husband. Was she really guilty? Carla sets about solving the puzzle by turning detective and questions all the people present on that day 16 years ago. Will her mother prove to be innocent?
