Agatha Christie’s iconic thriller The Mousetrap celebrates its 30,000th performance in the West End today and extends booking through to spring 2026. The genre-defining murder mystery, which opened in 1952, continues to captivate audiences at London’s St Martin’s Theatre more than 70 years on.
Marking this milestone, Guinness World Records adjudicator Will Munford presented the company with a certificate for the record title of longest theatrical run. Craig Glenday, Editor in Chief, said: “Guinness World Records has monitored this category from the very first edition in 1955. The Mousetrap overtook the previous holder in 1958, making it one of the all-time longest-standing world records.”
Brian Fenty, Producer of The Mousetrap, remarked: “As The Mousetrap celebrates its record-shattering 30,000th performance, I’m reminded daily of the timeless genius behind Agatha Christie’s work and her landmark Whodunnit. It’s an honour to carry forward this legacy, proof that remarkable storytelling can unite audiences across generations—and endure for decades to come.”
Continuing the celebrations, a special schools matinee performance was held with over 400 children from schools across London attending the play this afternoon at St Martin’s Theatre.
The current cast of The Mousetrap includes Lara Lemon as Mollie Ralston, Harry Bradley as Giles Ralston, Richard Leeming as Christopher Wren, Rekha John-Cheriyan as Mrs Boyle, Owen Oakeshott as Major Metcalf, Grace Darling as Miss Casewell, Alasdair Buchan as Mr Paravicini, and Daniel Rainford as Detective Sgt. Trotter, along with Liv Koplick, Clive Marlowe, Richard Parnwell, Ben Riddle, and Cathryn Sherman.
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, directed by Philip Franks, and the Artistic Director is Denise Silvey.
