Photos: THE MOUSETRAP Celebrates Guinness World Record Breaking 30,000th Performance

Agatha Christie’s iconic thriller The Mousetrap celebrates its 30,000th performance in the West End today and further extends booking through to spring 2026. The genre-defining murder mystery opened in 1952 and continues to run at London’s St Martin’s Theatre, more than 70 years on.

Marking the milestone, Guinness World Records adjudicator Will Munford presented the company with a certificate for the record title longest theatrical run. Craig Glenday, Editor in Chief says: “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." See photos here!

Who will be their next victim?
