★★★☆☆
Few plays can claim the extraordinary theatrical legacy of Agatha Christie’s The Mousetrap. First performed in 1952, this enduring murder mystery has entertained generations of audiences, and its 75th-anniversary tour offers an opportunity to experience a piece of British theatrical history. As the world’s longest-running play, I was curious to see what has kept audiences coming back for more than seven decades. I enjoyed the evening, especially the performances and the clever lighting, though I left with mixed feelings about the story itself.
The play is set in Monkswell Manor, a guesthouse newly opened by Mollie (Emily Laing) and Giles Ralston (Jack Hardwick). A group of strangers arrive, a snowstorm cuts them off from the outside world, and news of a murder in London soon turns an otherwise ordinary gathering into something much more unsettling. Everyone seems to have something to hide, and naturally, everyone becomes a suspect.
The cast generally does a good job of bringing these rather eccentric characters to life. I particularly enjoyed Jack Hardwick as Giles Ralston. His voice is wonderfully warm and soothing. His performance feels quite natural, even as his character becomes increasingly frustrated and suspicious. Thomas Barrett is also entertaining as Christopher Wren, the rather peculiar young architect. He is so obviously suspicious at times that I wondered whether he could be the murderer, or whether Christie was deliberately making things too obvious.
Emily Laing’s interpretation of Mollie Ralston is energetic and emotionally expressive, although at times I found her performance somewhat heightened compared with the rest of the cast. Mollie’s anxiety and emotional vulnerability are important to her character, and Laing clearly seeks to communicate these qualities. I understand that Mollie is meant to be anxious and emotionally vulnerable so this may well be a deliberate interpretation of the character. The frequent nervous movements and dramatic reactions occasionally felt a little excessive. A more restrained approach in certain moments might have allowed Mollie’s emotional development to emerge more gradually and created a stronger contrast as the tension intensified. This is perhaps more a matter of interpretation than a fundamental weakness in performance.
The rest of the cast, including Susan Penhaligon as Mrs Boyle, Nicholas Bailey as Major Metcalf and Alfie Richards as Sergeant Trotter, contribute well to the atmosphere of uncertainty.
One aspect I really appreciated was the lighting. With almost the entire play taking place in the same room, there is only so much you can do with the setting. Yet the lighting, designed by Nic Farman, is used very effectively to create suspense, particularly the moments surrounding the murder and the transition after the interval. The shifts between darkness and light make the familiar room suddenly feel threatening. Sometimes what we cannot see is more unsettling than what we can, and the production handled this particularly well.
My main reservations concern the script itself. While Christie is undeniably skilled at building suspense and misleading the audience, some characters’ decisions become increasingly hard to justify. Even as the danger becomes clearer, several keep concealing seemingly minor details about their movements and personal histories. Although these secrets serve the dramatic purpose of maintaining suspicion, they sometimes feel more like convenient devices than convincing human behaviour. I also found certain relationships developed rather suddenly. Some characters seem to become unusually attached to one another without much explanation, which made their behaviour a little difficult to understand. Perhaps these things are clearer if you’re already familiar with the original play but the story should communicate them to someone seeing it for the first time.
As for the mystery itself, I certainly did not guess the ending. It was a genuine surprise, and I enjoyed that. However, I also felt that the revelation came rather abruptly. Part of the pleasure of a good detective story is examining the clues, forming your own theories, and eventually realising how everything fits together. Here, I was surprised, but I did not quite have that satisfying moment of thinking, “Of course! I should have seen that coming.”
That said, I really liked the ending of the theatrical experience itself. After the curtain call, the audience was asked to keep the identity of the murderer a secret. I found this a lovely tradition, and perhaps one of the evening’s most memorable parts. There is something rather special about knowing that generations of audiences have been asked to make the same promise.
The Mousetrap is an enjoyable evening at the theatre, with some lovely performances, effective lighting, and a mystery that still manages to surprise. I am not entirely convinced by the story’s logic but I can appreciate its charm and its place in British theatre history. And, of course, I’d like to follow the tradition and keep the secret. If you want to know who the murderer is, you’ll have to go and see it for yourself.
Agatha Christie’s The Mousetrap runs at Palace Theatre Manchester until October 31st 2026 (fittingly!) and tours the UK until July 17 2027. It is currently booking at St. Martin’s Theatre in the West End until the same dare.
