About the show
Agatha Christie's murder mystery and the longest-running play in the history of world theatre.
The Mousetrap has been running in London since 1952. Audiences are asked, by tradition, not to share the ending. Agatha Christie's locked-house whodunit takes place at Monkswell Manor during a snowstorm, where the houseguests start dying. It is a useful piece of London theatre history as much as a night out. Running time is roughly two hours and fifteen minutes with an interval. Suitable for ages twelve and up.
