Producer Brian Fenty has announced the principal cast of the 75th anniversary UK tour of The Mousetrap, Agatha Christie's iconic thriller and the world's longest running play. The tour begins in Birmingham on 3 September 2026, running through to 2027 and visiting over 25 cities across the UK.
The tour welcomes new director Hannah Chissick who, together with casting director Denise Silvey, has assembled the company that will take The Mousetrap into its 75th anniversary.
Joining the cast are Emily Laing (One Life) as Mollie Ralston, Jack Hardwick (The Bodyguard UK tour) as Giles Ralston, Thomas Barrett (Summer Folk, National Theatre) as Christopher Wren, Clare Duffy (Pipe Dream, Union Theatre) as Miss Casewell, James Peake (The Invisible Man, Eastbourne Theatres) as Mr Paravicini and Alfie Richards (The Lion The Witch and The Wardrobe, UK tour) as Detective Sergeant Trotter.
They join the previously announced Nicholas Bailey (EastEnders) as Major Metcalf and Susan Penhaligon (A Fine Romance) as Mrs Boyle.
Since 1952, The Mousetrap has captivated the world with silent clues, shifting shadows and the best-kept secret in theatre history. A shocking murder rattles London and, far from the chaos, seven strangers seek refuge in a remote guesthouse. But when a police detective battles through a deadly snowstorm with a warning no one expects, it becomes clear the threat is already within their walls.
Earlier this year the play celebrated its 30,000th performance in the West End and was presented with a Guinness World Records certificate for the record title of longest theatrical run. The genre-defining murder mystery opened in 1952 and continues to enthral audiences at London's St Martin's Theatre, now booking into its 75th year in 2027.
The tour is directed by Hannah Chissick with lighting design by Nic Farman, casting by Denise Silvey and resident director Myles Brown. The Mousetrap is produced by Brian Fenty.
