Last year the play celebrated its 30,000th performance in the West End and was presented with a Guinness World Records certificate for the record title longest theatrical run. The genre-defining murder mystery opened in 1952 and continues to enthral audiences at London’s St Martin’s Theatre, more than 73 years on. It is currently booking through to January 2027.
As news spreads of a murder in London, a group of seven strangers find themselves snowed in at Monkswell Manor, a remote countryside guesthouse. When a police sergeant arrives, the guests discover – to their horror – that a killer is in their midst. One by one, the suspicious characters reveal their sordid pasts. Which one is the murderer? Who will be their next victim?
The Mousetrap is produced by Brian Fenty and directed by Denise Silvey.
