Yes, The Mousetrap is London’s longest-running play. It also holds the title of the longest-running play in the world. It premiered in London on 6 October 1952, at the Ambassadors Theatre, and later moved to the larger St. Martin’s Theatre in 1974, where it continues to run.
As of now, the play has been performed continuously for over 70 years, with tens of thousands of performances, making it a landmark in theatrical history. This remarkable longevity is a testament to its enduring appeal and the intrigue of its cleverly constructed murder mystery.
What is The Mousetrap and why is it so famous?
The Mousetrap is a murder mystery written by Agatha Christie, and holds the record as the world’s longest-running play.

Audiences are asked to keep the ending secret, adding to the play’s intrigue.
The play’s fame stems from its longevity, Christie’s legacy as the “Queen of Crime,” and its classic whodunit format, which traps both characters and viewers in suspense.

The peace is shattered when news breaks of a local murder, and the police warn that the killer may be headed their way. Tensions rise when a police officer arrives on skis to investigate, and the guests realise the murderer might already be among them.
As suspicions grow and secrets unravel, another murder occurs within the house, plunging everyone into chaos. The play builds to a dramatic climax, revealing the killer’s identity in a shocking twist. The mystery is a masterclass in suspense, full of red herrings, misdirection, and psychological intrigue, keeping audiences guessing until the final moment.

Meet The Mousetrap suspects
Welcome to Monkswell Manor, where a snowstorm has trapped seven strangers — and one of them is a killer. Agatha Christie's The Mousetrap isn’t just the world’s longest-running play — it’s also a brilliantly tangled web of secrets, lies, and red herrings. With over 28,000 performances since its West End debut in 1952, this murder mystery classic has become a London theatre legend, even picking up the Laurence Olivier Award for Special Recognition in 2022. But who are the shadowy characters hiding behind their polished facades? Let’s meet the suspects…
Mollie Ralston
The warm and welcoming owner of Monkswell Manor, Mollie has a genteel charm and a calming presence — the perfect host. But behind her gracious smile lies a quiet nervousness, and a reluctance to share details about her past. Could her kindness be a cover for something more sinister? With all eyes on the guests, is it possible the killer is the one pouring the tea?
Giles Ralston
Mollie’s husband and co-proprietor of the manor, Giles is protective, proud, and a little quick to point fingers. His aloofness can be chalked up to the stress of hosting under extreme weather… or it might be something darker. A man with a strong sense of privacy and the occasional flare of jealousy, Giles has a temper that could boil over at the worst possible time.
Christopher Wren
An exuberant, jittery young man with a love for architecture and a flair for the eccentric, Christopher Wren is immediately memorable — and that’s exactly how he likes it. But his erratic behaviour and sudden outbursts make the other guests uneasy. He’s either harmlessly odd… or hiding something too big for even him to control.
Mrs. Boyle
Opinionated, entitled, and unashamedly vocal about her dissatisfaction with everything from the furniture to the food, Mrs. Boyle has a talent for alienating everyone in the room. Her air of superiority hints at a long history of judgement and secrets. She’s the kind of person who makes enemies easily — but could she also be capable of murder?
Major Metcalf
With his military bearing and calm, methodical way of speaking, Major Metcalf appears to be a figure of order amidst the chaos. But when it comes to the past, he’s suspiciously vague. Is he simply a stiff-upper-lip type with nothing to hide, or is he blending in just a little too well?
Miss Casewell
Mysterious, stylish, and emotionally guarded, Miss Casewell has an unsettling air of detachment. Her cryptic remarks and unnerving calm suggest a traumatic history that still casts a long shadow. She’s returned to England after years abroad — but why now? And why here?
Mr. Paravicini
He appears out of the snow with a dramatic flair, claiming his car overturned in the storm. Paravicini is flamboyant, theatrical, and utterly unreadable. His stories don’t quite add up, his accent seems oddly changeable, and no one knows why he really came to Monkswell Manor. Is he a harmless eccentric… or something much more dangerous?
Detective Sergeant Trotter
Skiing in through the blizzard to warn of a potential murder and investigate a recent crime, Sergeant Trotter is all business. Methodical, thorough, and determined to get to the bottom of things, he wastes no time in interrogating the manor’s guests. But with so many stories not lining up and tensions rising by the hour, he’ll need every ounce of intuition to catch the killer before they strike again.
Now you’ve met the suspects, why not further your investigations and uncover the cast of characters that play them?
So, who did it?
Over 70 years since its premiere, The Mousetrap continues to enthral audiences night after night with its perfectly plotted twists, eccentric suspects, and that famously shocking final reveal. Whether you're a seasoned sleuth or a first-time theatre-goer, one thing’s for certain: nothing is quite what it seems at Monkswell Manor.
And remember — once you know the ending… shhh! Keep the secret.

Meet the cast of The Mousetrap
Agatha Christie's The Mousetrap continues its unparalleled run at London's St. Martin's Theatre, captivating audiences with its intricate plot and rich history. Since its West End debut on November 25, 1952, the play has achieved remarkable milestones, including over 29,000 performances and more than 10 million tickets sold. In 1974, the production seamlessly transferred from the Ambassadors Theatre to St. Martin's Theatre without missing a single performance, showcasing the dedication of its team. To date, The Mousetrap has featured no fewer than 297 actors and actresses. Notably, David Raven holds the Guinness World Record as the 'Most Durable Actor' for his 4,575 performances as Major Metcalf, and the late Nancy Seabrooke set a record with her 15-year tenure as an understudy.
Under the direction of Philip Franks, who joined the production as director in May 2024, this enigmatic ensemble cast continues to uphold the legacy of The Mousetrap, bringing the eccentric cast of characters to life (and death) each night. The current cast brings fresh energy and talent to this timeless classic:
Who plays Mollie Ralston in The Mousetrap?
Lara Lemon takes on the role of Mollie Ralston. No stranger to an Agatha Christie thriller, Lemon was most recently seen in Witness for the Prosecution, where she delivered not just one, but two standout performances, taking on the roles of Greta and Clegg. Lemon's nuanced portrayal of Mollie adds depth to the character, drawing viewers into the suspenseful world of Monkswell Manor.
Who plays Giles Ralston in The Mousetrap?
Harry Bradley brings a dynamic energy to the stage in his performance as Giles Ralston. Audiences may recognize him from another long-running hit - The Play That Goes Wrong - where his comedic timing and versatility were on full display. Bradley's interpretation of Giles balances charm and tension, contributing significantly to the play's intricate narrative.
Who plays Christopher Wren in The Mousetrap?
Richard Leeming leaps into the shoes of the enigmatic and eccentric Christopher Wren. Recently seen in Regent Park Open Air Theatre’s production of Romeo & Juliet and The Haunting at New Vic, Leeming captures Wren's eccentricities and mystery, keeping audiences guessing about his true intentions.
Who plays Mrs. Boyle in The Mousetrap?
Rekha John-Cheriyan delivers a commanding performance as the stern and critical Mrs. Boyle. Her recent role in the national and international tour of The Best Exotic Marigold Hotel showcased her ability to embody complex characters, and she brings the same depth to her portrayal of Mrs. Boyle, adding layers to the play's suspense.
Who plays Major Metcalf in The Mousetrap?
Owen Oakeshott takes on the role of Major Metcalf, infusing the character with authenticity and gravitas. Another Witness for the Prosecution alumni, Oakeshott demonstrated his unparalleled range in the courtroom thriller. Oakeshott's Major Metcalf is both reassuring and enigmatic, contributing to the play's intricate web of suspicion.
Who plays Miss Casewell in The Mousetrap?
Grace Darling makes her West End debut to play the enigmatic Miss Casewelly. Though her role in the Edinburgh Fringe hit Queen has already made her theatre royalty! She brings a fresh perspective to Miss Casewell, keeping audiences intrigued by her mysterious past.
Who plays Mr. Paravicini in The Mousetrap?
Alasdair Buchan brings charisma and intrigue to the role of Mr. Paravicini. No stranger to a detective drama, his previous work includes An Inspector Calls and Sherlock Holmes and the Crimson Cobbles. Interestingly, Buchan's connection to The Mousetrap dates back to his childhood when he staged an unauthorized school production, leading to a legal warning from the producers. Now, he joins the official West End cast, bringing his journey full circle.
Who plays Detective Sergeant Trotter in The Mousetrap?
Daniel Rainford steps into the role of Detective Sergeant Trotter, bringing determination and intensity to the character. His lead performance in Private Peaceful showcased his ability to portray contradictory and complex emotions, and as Trotter, he keeps the audience engaged as he unravels the mystery at Monkswell Manor.
The Mousetrap full West End cast
The Mousetrap West End cast is completed by Liv Koplick (Understudy Mollie/Casewell/ASM), Clive Marlowe (Understudy Major Metcalf & Mr Paravicini), Richard Parnwell (Understudy Christopher Wren/Trotter/ASM), Ben Riddle (Understudy Trotter/Ralston) and Catherine Sherman (Understudy Mrs. Boyle)

St. Martin's Theatre best seats and seating plan
London's charming St. Martin's Theatre has been a beacon of theatrical excellence for over a century. Since opening its doors in 1916, this historic venue has been home to countless unforgettable performances, including the legendary long-running show The Mousetrap. With a capacity of just over 550 seats, every show at St Martin's is an intimate experience. If you're planning a visit to witness the magic on stage, choosing the perfect seat can make all the difference. To ensure you have an optimal view of the captivating performances, keep reading to discover which seat will offer you the best vantage point and make your night truly memorable.
What are the best seats at the St. Martin's Theatre?
Starting with the Stalls, Row G seats are widely considered the most desirable in the theatre, thanks to the generous legroom provided by the aisle in front and an outstanding view of the full stage. However, the last three rows do experience some partial obstruction of the view due to the overhang from the Dress Circle.
Up in the Dress Circle, the rake provides excellent views even from the back row, but the front two rows offer some of the best sightlines in the theatre. Due to the more intimate scale of St Martin’s Theatre, the Dress Circle feels closer to the stage compared to larger West End venues. However, as with many historic theatres, legroom can be a bit limited.
The Upper Circle provides the most budget-friendly tickets in the theatre. Views from this section can feel distant, and the first few rows may be partially obstructed by a safety rail. Legroom tends to be quite cramped. Row H, while the furthest from the stage, offers slightly better legroom than most of the Upper Circle, making it a good option for taller patrons who are mindful of their budget.

The Mousetrap’s Miles Richardson tells us what makes his spring, spectacular
He may play a retired army general in The Mousetrap, but in real-life Miles Richardson is a (nature)lover, not a fighter. The eco-friendly thespian loves nothing more than enjoying the capital in bloom, taking in the wisteria and bluebells (and taking home any rubbish) on his journey to St Martin’s Theatre.
However, he may not have been making this commute if it wasn’t for his clean-shaven take on the Major! “The first thing [my wife] asked me when I found out I got the part was ‘would I have to grow any facial hair’. When I said No, she said I could do the job!” So, he was a whisker away from not clinching the part, literally!
We sat down with Miles to discuss songs, post-show drinks, and what makes his spring, spectacular.
