The 75th Anniversary Tour of Agatha Christie's classic murder mystery 'The Mousetrap', with Susan Penhaligon and Nicholas Bailey.
The Mousetrap comes to the Wyvern Theatre from 22 to 27 February 2027, as part of its 75th Anniversary Tour across the UK and Ireland. It's Agatha Christie's classic murder mystery, the one that's become a bit of a British institution in its own right.
The story is set at Monkswell Manor, a remote guesthouse where seven strangers are snowed in and discover a killer is among them. It's a proper closed-circle mystery — everyone's trapped in the same house, and the murderer has to be one of the people in the room. The play is based on Christie's radio play Three Blind Mice, and it's billed as the world's longest-running play and 'the cleverest murder mystery of British Theatre'.
That longevity is something of a legend. It opened in the West End in 1952 at St Martin's Theatre, where it's been running for more than 70 years and over 30,000 performances, making it as much of a London icon as Big Ben or Buckingham Palace. Christie herself gave it eight months 'at most', and she staged it on the strict condition that no audience or press member ever give away the plot. She also stipulated that a film adaptation could only be made six months after the West End production closed — a clause that's made a film unlikely. The 75th Anniversary Tour brings that same production to the Wyvern, so the secret is still the secret.
