Overview

The Mousetrap traps a group of strangers in a snowbound guesthouse with a murderer among them — a classic Agatha Christie whodunnit that's become as famous for its longevity as for its plot. It opened in the West End in 1952 and has run continuously since (aside from a brief pandemic closure), making it the longest continuously running play anywhere in the world.

Audiences are traditionally asked not to reveal the ending after the show — a tradition that's stuck for over 70 years and is very much part of the fun of going.

Visitor information

St Martin's Theatre is a small, traditional playhouse just off Leicester Square, in the heart of Theatreland.

Getting there

Leicester Square Underground is a couple of minutes' walk away.

Age guidance

Suitable for most ages from around 10 up; it's a classic mystery thriller with mild suspense rather than graphic content.

Accessibility

Wheelchair-accessible seating is available and should be arranged with the box office in advance given the theatre's smaller, older layout.

Frequently asked questions
