About the show
Agatha Christie's legendary whodunnit has been keeping audiences guessing at the St Martin's Theatre since 1952. The world's longest-running play, The Mousetrap celebrated its 30,000th performance in March 2025 and holds a Guinness World Record for the longest theatrical run in history. Can you solve the mystery before the final curtain falls? Keep the secret!
What is The Mousetrap about?
Agatha Christie's The Mousetrap is the longest-running show in the world, playing continuously in London since 1952. A group of strangers is snowed in at a countryside guest house when a police sergeant arrives with disturbing news: a murderer is on the loose, and one of them may be the killer. As the tension mounts and the bodies begin to fall, everyone has a secret and everyone is a suspect. The play's ending has been kept secret by audiences for over 70 years.
Why see The Mousetrap?
The Mousetrap is a piece of London theatrical history. Seeing it is not just watching a play: it is participating in a tradition that has run unbroken for more than seven decades. The whodunit plot is expertly constructed (Christie was the queen of misdirection for good reason), the atmosphere is genuinely suspenseful, and the famous twist ending is still being protected by every audience that sees it. At the end, every audience is asked not to reveal the identity of the murderer. It is a shared secret that connects millions of theatregoers across generations.
Practical information for visitors
The Mousetrap plays at St Martin's Theatre in the West End. Tickets start from £30. The show is suitable for all ages, though younger children should be comfortable with a two-hour running time and suspenseful atmosphere. St Martin's Theatre is located on West Street, near Leicester Square tube station.
