The play's title derives from Shakespeare's tragedy Hamlet, in which “The Mousetrap” is Hamlet's answer to his murderous uncle Claudius's inquiry about the name of the play whose prologue and first scene the court has just seen.
The play is actually called 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”.
