Trotter. Completing the cast are Nancy Doubledee, Bella Farr, Barnaby Jago, Richard Parnwell and Clive Marlowe.

Directed by Denise Silvey, The Mousetrap is a thrilling murder mystery whodunnit with a twist ending that has infamously remained under wraps. It follows a group of seven strangers who find themselves snowed in at Monkswell Manor, a remote countryside guesthouse, as news spreads of a murder in London. 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?

Last year, The Mousetrap 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. Since opening in 1952, it has continued to enthrall audiences in London for over 73 years.

The Mousetrap is currently playing at St Martin's Theatre and booking until January 2027.
