Almost sixty years on and we still don't know whodunnit! A group of people are gathered together in a remote part of the countryside, and one of them is a murderer. Agatha Christie's classic thriller continues on the world's longest run.
For the last 34 years the St Martin's has been the home of The Mousetrap, more than half of its record breaking run!
The Mousetrap has been thrilling audiences from around the world for as long as HRH Queen Elizabeth II has been on the throne. On the 25th of November 2002 a Royal Gala Performance was held, attended by Her Majesty The Queen and The Duke of Edinburgh.
During this phenomenal run there have been no fewer than 382 actors and actresses appearing in the play, 116 miles of shirts have been ironed and over 415 tons of ice cream sold.
Some cast members are in the Guinness Book of Records, David Raven as the 'Most Durable Actor' for 4575 performances as Major Metcalf, and the late Nancy Seabrooke for a record breaking 15 years as an understudy.
The Mousetrap first entered the record books many years ago on 12th April 1958 when it became the longest running show of any kind in the history of British Theatre.
In 2000 the set was replaced for the first time during the run at St Martin's Theatre, still to the same design as the original. This task was completed over a weekend without the loss of a performance.
