The Mousetrap is a murder mystery play by Agatha Christie. The Mousetrap opened in the West End of London in 1952, and has been running continuously since then. It has by far the longest initial run of any play in history, with its 25,000th performance taking place on 18 November 2012. It is the longest running show (of any type) of the modern era. The play is also known for its twist ending, which the audience are traditionally asked not to reveal after leaving the theatre.
The play began life as a short radio play broadcast on 30 May 1947 called Three Blind Mice in honour of Queen Mary, the consort of King George V. The play had its origins in the real-life case of the death of a boy, Dennis O'Neill, who died while in the foster care of a Shropshire farmer and his wife in 1945.
The play is based on a short story, itself based on the radio play, but Christie asked that the story not be published as long as it ran as a play in the West End of London. The short story has still not been published within the United Kingdom but it has appeared in the United States in the 1950 collection Three Blind Mice and Other Stories.
When she wrote the play, Christie gave the rights to her grandson Matthew Prichard as a birthday present. In the United Kingdom, only one production of the play in addition to the West End production can be performed annually, and under the contract terms of the play, no film adaptation can be produced until the West End production has been closed for at least six months.
The play had to be renamed at the insistence of Emile Littler who had produced a play called Three Blind Mice in the West End before the Second World War. The suggestion to call it The Mousetrap came from Christie's son-in-law, Anthony Hicks. In Shakespeare's play Hamlet, "The Mousetrap" is Hamlet's answer to Claudius's inquiry about the name of the play whose prologue and first scene the court has just observed (III, ii). The play is actually The Murder of Gonzago, but Hamlet answers metaphorically, since "the play's the thing" in which he intends to "catch the conscience of the king."
The play's longevity has ensured its popularity with tourists from around the world. In 1997, at the initiative of producer Stephen Waley-Cohen, the theatrical education charity Mousetrap Theatre Projects was launched, helping young people experience London's theatre.
As a stage play, The Mousetrap had its world premiere at the Theatre Royal, Nottingham on 6 October 1952. It was originally directed by Peter Cotes, elder brother of John and Roy Boulting, the film directors. Its pre-West End tour then took it to the New Theatre Oxford, the Manchester Opera House, the Royal Court Theatre, Liverpool, the Theatre Royal, Newcastle, the Grand Theatre Leeds and the Alexandra Theatre in Birmingham before it began its run in London on 25 November 1952 at the Ambassadors Theatre. It ran at this theatre until Saturday, 23 March 1974 when it immediately transferred to the larger St Martin's Theatre, next door, where it reopened on Monday, 25 March thus keeping its "initial run" status. The London run has now exceeded 25,000 performances. The director of the play for many years has been David Turner.
Christie herself did not expect The Mousetrap to run for such a long time. In her autobiography, she reports a conversation that she had with Peter Saunders: "Fourteen months I am going to give it", says Saunders. To which Christie replies, "It won't run that long. Eight months perhaps. Yes, I think eight months." When it broke the record for the longest run of a play in the West End in September 1957, Christie received a mildly grudging telegram from fellow playwright Noël Coward: "Much as it pains me I really must congratulate you ..." In 2011 (by which time The Mousetrap had been running for almost 59 years) this long-lost document was found by a Cotswold furniture maker who was renovating a bureau purchased by a client from the Christie estate.
The original West End cast included Richard Attenborough as Detective Sergeant Trotter and his wife Sheila Sim as Mollie Ralston. They took a 10% profit-participation in the production, which was paid for out of their combined weekly salary ("It proved to be the wisest business decision I've ever made... but foolishly I sold some of my share to open a short-lived Mayfair restaurant called 'The Little Elephant' and later still, disposed of the remainder in order to keep Gandhi afloat.")
Since the retirement of Mysie Monte and David Raven, who each made history by remaining in the cast for more than 11 years, in their roles as Mrs Boyle and Major Metcalf, the cast has been changed annually. The change usually occurs around late November around the anniversary of the play's opening, and was the initiative of Sir Peter Saunders, the original producer. There is a tradition of the retiring leading lady and the new leading lady cutting a "Mousetrap cake" together.
The play has also made theatrical history by having an original "cast member" survive all the cast changes since its opening night. The late Deryck Guyler can still be heard, via a recording, reading the radio news bulletin in the play to this present day. The set has been changed in 1965 and 1999, but one prop survives from the original opening – the clock which sits on the mantelpiece of the fireplace in the main hall.
Notable milestones in the play's history include:
- 22 April 1955 – 1,000th performance
- 13 September 1957 – Longest-ever run of a "straight" play in the West End
- 12 April 1958 – Longest-ever run of a show in the West End with 2239 performances (the previous holder was Chu Chin Chow)
- 9 December 1964 – 5,000th performance
- 17 December 1976 – 10,000th performance
- 16 December 2000 – 20,000th performance
- 25 November 2002 – 50th anniversary; a special performance was attended by Queen Elizabeth II and Prince Philip, Duke of Edinburgh
- 18 November 2012 – 25,000th performance
In May 2001 (during the London production's 49th year, and to mark the 25th anniversary of Christie's death) the cast gave a semi-staged Sunday performance at the Palace Theatre, Westcliff-on-Sea as a guest contribution to the Agatha Christie Theatre Festival 2001, a twelve-week history-making cycle of all of Agatha Christie's plays presented by Roy Marsden's New Palace Theatre Company.
A staging at the Toronto Truck Theatre in Toronto, Ontario, that opened on 19 August 1977 became Canada's longest running show, before finally closing on 18 January 2004 after a run of twenty-six years and over 9,000 performances.
On 18 November 2012, both the 25,000th performance and the 60th year of the production were marked by a special charity performance which featured Hugh Bonneville, Patrick Stewart, Julie Walters and Miranda Hart. The money raised by the performance went towards Mousetrap Theatre Projects.
During the Diamond Anniversary year of 'The Mousetrap', a touring production visited regional theatres for the first time in its history, whilst the London run continued uninterrupted.

Twist ending and tradition of secrecy
The murderer's identity is divulged near the end of the play, in a twist ending which is unusual for playing with the very basis of the traditional whodunnit formula, where the cliché is that the detective solves the crime and exposes the remaining plot secrets. By tradition, at the end of each performance, audiences are asked not to reveal the identity of the killer to anyone outside the theatre, to ensure that the end of the play is not spoiled for future audiences.
Christie was always upset by the plots of her works being revealed in reviews, and in 2010 her grandson Matthew Prichard, who receives the royalties from the play, was "dismayed" to learn from The Independent that the ending to The Mousetrap was revealed online in the play's Wikipedia article.
The play is set in the Great Hall of Monkswell Manor, in what Christie described as "the present".
Act I opens with the murder of a woman named Maureen Lyon, played out in sound only on a dark stage representing London. The action then moves to Monkswell Manor, recently converted to guesthouse and run by a young couple, Mollie and Giles Ralston. The inexperienced Ralstons are nervous to be hosting their first guests in the midst of a paralyzing snow storm, but they are determined to make a go of things. While waiting for the guests to begin arriving, Mollie listens to a radio report about the Lyon murder, which notes that police are looking for a man in a dark overcoat who was observed near the scene.
Their first four guests, all of whom have made their travel arrangements via writing to the guest house and none of whom have submitted references, arrive. Christopher Wren is an unkempt, flighty young man who tells Mollie that he is an architect, named as he is because his parents hoped for him to be like Christopher Wren. Giles and Mollie both react strongly to Wren, Giles with instant dislike and Mollie with instant, instinctual trust. Mrs Boyle and Major Metcalf then arrive together, having been forced to share a taxi from the train station. Mrs Boyle is a heavyset woman of a certain age who complains freely about everything in the guesthouse but declines Giles Ralston's offer to cancel her reservation. In contrast, Metcalf is an amiable ex-military man. Miss Casewell, a mannish young woman in a dark coat, is the last of the arranged guests to arrive, but just as the company is settling down, an unexpected fifth party arrives. Identifying himself in a foreign accent as Mr Paravicini, he tells the Ralstons that his car has overturned in a snowdrift. He notes that the snow has rendered roads impassable and that the denizens of the house are essentially trapped. Despite being uneasy about Paravicini's manner, Mollie places him in the last remaining room.
Scene II opens the next afternoon. The guest house is, indeed, snowed in, and the inmates are somewhat restless. Mollie answers the ringing telephone and is surprised to find herself speaking to Superintendent Hogben of the Berkshire Police. Hogben tells her that he is dispatching a man named Sergeant Trotter to the guest house, and that the Ralstons must listen carefully to what Trotter has to tell them. Apprehensively, the Ralstons try to think of what they could have done to garner police attention, but can come up with nothing sufficiently serious to bring out a police sergeant in a snowstorm.
Though the Ralstons are doubtful that anyone could get through the snow to the house, a tap on the window proves them wrong, bringing a friendly young man on skis who identifies himself as Detective Sergeant Trotter. As Giles goes off with the Trotter to store his skis, Major Metcalf discovers that the phone has stopped working, cutting off the household's last lifeline to the outside world.
Trotter and Giles return and Trotter explains his purpose to the household: he has been sent in regard to the murder of Maureen Lyon. The dead woman's real name was not Lyon, but Stanning, and she and her husband had once been at the center of a horrific child abuse case at a farm near Monkswell Manor (taking features from the real Dennis O'Neill case). The couple had fostered three children named Corrigan, two boys and a girl who were wards of the court, but had mistreated the children so severely that the youngest boy had died. After being rescued from the Stanning farm, the remaining children had fallen off the radar; the girl was adopted by an unknown family, and the elder boy joined the army, deserted, and then disappeared. Both Mr and Mrs Stanning were sentenced to prison for their actions; the husband died there, while the wife had served her sentence and been released, only to be found strangled under the name of Maureen Lyon. Based on what little they know about the remaining Corrigan children, police suspect the elder boy, who would now be twenty-two, of being the killer.
The reason Trotter is interested in Monkswell Manor, he reveals, is that a notebook was found at the scene of the murder containing two addresses: Lyon's and that of Monskwell Manor. Also in the notebook was the inscription "Three Blind Mice," and a note reading "This is the First" was pinned to the body. The police have sent Trotter to find out how the Ralstons' guest house is connected to the Corrigan children's tragedy, and whether the residents of the house are in danger as a result. Both Giles and Mollie deny having any connection to the Corrigan children's case, though Mollie is ill at ease answering Trotter's questions and quickly excuses herself. With nothing else to go on, Trotter turns to the guests and asks each of them to explain how they have come to be at Monkswell Manor and what their connection to the Corrigans is. All five guests deny any personal knowledge of the Corrigan case, and Trotter impatiently declares that if one of them dies, it will be their own fault.
Trotter and Giles set off on a tour of the house, while the guests remain in the sitting room to discuss the alarming turn of events. Major Metcalf confronts Mrs Boyle, revealing that she was actually one of the magistrates who had been responsible for assigning the Corrigan children to the Stannings' care. Mrs Boyle takes this in stride, acknowledging its truth but denying that she has any responsibility for what eventually happened to the children there, as the Stannings had seemed like a fine sort of people at the time.
As the evening wears on, the household cannot rest easy. Giles and Mollie become suspicious of each other while the guests snipe at one another. Sergeant Trotter, upon finding out that the telephone is out of service, points out that it needn't be an issue of the murderer arriving to kill someone in the house; it could very well be an issue of the murderer being someone who is already in the house. He goes offstage, tracing the phone wire to find out if it has been cut. Mrs Boyle wanders back into the now-empty room and begins listening to the radio. The opening notes of "Three Blind Mice" are heard whistled by an unknown party, and Mrs Boyle responds without alarm, speaking to the person only she can see. Suddenly, the lights go out and a scuffle is heard. Moments later, Mollie walks into the room and turns on the lights, only to find Mrs Boyle dead on the floor.
Ten minutes after Mollie found Mrs Boyle dead of strangulation, Sergeant Trotter has taken charge of the household. All the remaining residents are gathered in one room as he attempts to sort out the events of the evening. A shaken Mollie Ralston is unable to provide him with any useful clues; the only thing she is sure she observed was the radio blaring. Frustrated, Trotter points out that as long as the people of the house continue to refuse to give him information, their lives continue to be in danger; a third murder could very well occur, given that the notes left with Maureen Lyon specified three "blind mice", but only two addresses. He insists that everyone tell him where they were when the murder of Mrs Boyle occurred. As each person recounts their whereabouts, Trotter taxes them to account for inconsistencies or weaknesses in their stories. Finally, he declares that everyone in the house had the opportunity to commit the murder, since each of them was alone at the time it happened. Giles counters that while seven people in the house lack alibis, only one fits the description of the early-twenties young man the police suspect to be the murderer: Christopher Wren. Wren insists that it's all a frame-up, and Trotter acknowledges that he lacks any evidence pointing to Wren in particular.
Mollie later pulls Trotter aside and elicits from him the fact that while police suspect the elder boy to be the killer, the dead boy also had relatives and loved ones who might be interested in revenge: the children's father, an Army sergeant whose current identity and whereabouts are unknown, for example; or the female child, the dead boy's sister, who would now be a young woman. Trotter notes that Metcalf or Paravicini could the father, Miss Casewell or Mollie Ralston herself could be the sister, and even Giles Ralston could be hiding an identity as the elder boy. Mollie, aghast, protests the notion that either she or Giles could be a murderer, but Trotter forces her to admit that they haven't been married for long, and know little about each other's pasts.
Mollie soon finds herself in conversation with Christopher Wren, who confesses that he is actually an Army deserter hiding from his past and has been at Monkswell Manor under a false name. Mollie acknowledges to him that she, too, is running away from traumatic events in her past. Despite the trust Christopher and Mollie are forming between them, he and Giles each suspect the other and nearly come to blows over who can safely be alone with Mollie. The situation is only defused by the arrival of Paravicini, who tells the company that Trotter has discovered his skis are missing and someone may be preparing to escape the house.
Trotter again calls an assembly of the household, declaring that he now intends to check the alibis everyone provided to him after Mrs Boyle's murder. They will re-enact the murder, with each member of the household playing the part of another member and acting out their alibi. Trotter's hope is that while the most of the alibis will be verified, one will be proved impossible. Each person is to go to their assigned position and stay there until summoned back by Trotter. The household obediently disperses, leaving Trotter alone onstage.
Identity of the murderer
After the role-players scatter, Trotter sits for a moment before calling for Mollie. He tells her that she has risked extreme danger by not identifying herself to him; he now knows that she was once the schoolteacher of the doomed Corrigan children. She failed to answer a letter the younger boy sent her at the time, begging to be rescued from the farm. Mollie protests that she had been been seriously ill when the letter arrived, and was unable to even read it until well after the boy was dead. To this day, she says, she is haunted by her failure to help the children out of their circumstances.
Trotter takes a gun out of his pocket and points it at Mollie, telling her that though she assumed he was a policeman, she only believed that because he had rung up beforehand, playing the role of his own superintendent. Trotter is, in fact, Georgie, the elder Corrigan brother, and he intends to take his revenge on Mollie. Falling back into the demeanor of a wounded child who never grew up, he drops his gun and begins to strangle her, but is stopped by the sudden appearance of Miss Casewell. Casewell calls him by name and reveals that she is Kathy, his long-lost sister, come to take him somewhere safe. Major Metcalf, who accompanied Miss Casewell into the room, summons Giles and tells the frightened innkeepers that he had known all along that Trotter wasn't a policeman - because Metcalf himself is a policeman, having arranged to switch places with the real Major Metcalf after discovering the "Three Blind Mice" notebook on Maureen Lyon. 
The play made little stir in the review pages of the British press when it opened. The Manchester Guardian commented that it was "a middling piece" with "less in it than meets the eye … Coincidence is stretched unreasonably." The critic commented that the characters were "built entirely of clichés". The reviewer in The Times was more favourably disposed to the characters, calling them "nicely assorted, individually labelled and readily identified", and found the plot "elaborately skilful." In The Daily Express John Barber praised "the atmosphere of shuddering suspense" but thought some of the characters "too obvious by half". In The Illustrated London News, J. C. Trewin commented that those who failed to spot the killer would probably call the plot "preposterous and over-burdened", but those who succeeded might be more kindly disposed.
The play was published as a paperback by Samuel French Ltd as French's Acting Edition No. 153 in 1954 and is still in print. It was first published in hardback in The Mousetrap and Other Plays by Dodd, Mead and Company in 1993 (ISBN 0-39-607631-9) and in the UK by Harper Collins in 1993 (ISBN 0-00-224344-X).
In 1959 it was announced producer Edward Small, who had brought Witness for the Prosecution to the screen, was to make a film version of the play in co-production with Victor Saville for United Artists. Tyrone Power and Maria Schell were named as leads. However no film version resulted.
In 1960, the Bengali author Premendra Mitra directed a film Chupi Chupi Aashey, based on the radio play and short story. This uncredited adaptation is possibly the only notable film version of The Mousetrap.
