The Mousetrap is a murder mystery play by Agatha Christie. The Mousetrap opened in London's West End in 1952 and ran continuously until 16 March 2020, when the stage performances had to be discontinued during the COVID-19 pandemic. The longest-running West End show, it has by far the longest initial run of any play in history, with its 27,500th performance taking place on 18 September 2018. The play has a twist ending, which the audience are traditionally asked not to reveal after leaving the theatre.
