Hamlet

The Tragedy of Hamlet, Prince of Denmark, often shortened to Hamlet, is a tragedy written by William Shakespeare sometime between 1599 and 1602. Set in Denmark, the play depicts Prince Hamlet and his revenge against his uncle, Claudius, who has murdered Hamlet's father in order to seize his throne and marry Hamlet's mother.

The Mousetrap
The Agatha Christie play Three Blind Mice had to be renamed at the insistence of Emile Littler who had produced a play called Three Blind Mice in the West End before the Second World War. The suggestion to call it The Mousetrap came from Christie's son-in-law, Anthony Hicks.

In Shakespeare's play Hamlet, "The Mousetrap" is Hamlet's answer to Claudius's inquiry about the name of the play whose prologue and first scene the court has just observed (III, ii). The play is actually The Murder of Gonzago, but Hamlet answers metaphorically, since "the play's the thing" in which he intends to "catch the conscience of the king."
