About The Mousetrap
The Mousetrap is the world's longest-running play — and one of London's most iconic theatrical experiences. Agatha Christie's legendary murder mystery has been thrilling audiences since 1952, and the twist ending has remained a closely guarded secret for over 70 years. Audiences are asked not to reveal who committed the murder, and remarkably, the secret has been kept.
Set in a snowed-in country house, a group of strangers find themselves trapped together when one of them is murdered. As suspicion falls on everyone, the tension builds to a shocking conclusion. At St Martin's Theatre in the heart of the West End, The Mousetrap is a piece of living theatre history — and a genuinely gripping whodunnit.
