The Mousetrap

Agatha Christie's The Mousetrap is the longest running show, of any kind, in the world. It opened in November 1952 at The Ambassadors Theatre in London and moved to St.Martin's Theatre in March 1974 where it is still running to this day.


The Mousetrap began as a radio play, titled Three Blind Mice, and was written at the request of the BBC for Queen Mary. Christie then expanded Three Blind Mice from a twenty minute radio play into a full length stage play, adding some extra characters and a fuller background and plot. The title was changed and The Mousetrap was created.

Before it opened, Agatha Christie gave the rights to The Mousetrap to her nine year old grandson, Mathew Prichard, without any idea that it would become a huge record breaking phenomenon. The Mousetrap opened on 25th November 1952, produced by Peter Saunders. Richard Attenborough and his fellow film star and beloved wife Sheila Sim played the leading roles as Detective Sergeant Trotter and Mollie Ralston. The late Deryck Guyler provided the pre-recorded voice of the newsreader in the first act and the same recording is still used today. In 1994 Sir Stephen Waley-Cohen became the producer of The Mousetrap.

Every performance of The Mousetrap sets a new world record for the number of performances and after each performance the audience is asked 'to preserve the tradition of The Mousetrap by keeping the secret locked in their hearts.'
