Agatha Christie’s renowned thriller The Mousetrap, which continues at London’s St. Martin’s Theatre, welcomes a new cast November 18.

The world's longest-running play now features Lara Lemon (Witness for the Prosecution) as Mollie Ralston, Harry Bradley (The Play That Goes Wrong) as Giles Ralston, Richard Leeming (The Haunting) as Christopher Wren, Rekha John-Cheriyan (The Best Exotic Marigold Hotel tour) as Mrs. Boyle, Owen Oakeshott (Land of the Free) as Major Metcalf, Grace Darling (Queen) as Miss Casewell, Alasdair Buchan (Accolade) as Mr. Paravicini, and Daniel Rainford (Laughing Boy) as Detective Sgt. Trotter.

The company also includes Liv Koplick, Clive Marlowe, Richard Parnwell, Ben Riddle, and Cathryn Sherman, who understudy various roles. This cast will continue through May 10, 2025.

Philip Franks directs; Denise Silvey is the artistic director.

In the play, adapted from the novel of the same name, a group of seven strangers find themselves snowed in at Monkswell Manor as news spreads of a London murder. When a police sergeant arrives, the guests discover that a killer is in their midst.

The Mousetrap premiered at Theatre Royal Nottingham in 1952 and toured the U.K. before opening in the West End, where it is entering its 73rd year. The production will play its 30,000th performance March 19, 2025.

In 2022, it was announced that The Mousetrap would come to Broadway. The producers behind the West End production of the play initially said the work would bow on the Main Stem in 2023, but a Broadway production has yet to materialize.

The Mousetrap is produced by Brian Fenty.
