Agatha Christie

• 1. Introduction

  ›

  Agatha Christie holds a record no living novelist can claim: more than two billion copies of her books sold, making her the best-selling fiction writer of all time. She wrote 66 detective novels and 14 short-story collections, and her stage play The Mousetrap has run without interruption in London's West End since 1952, logging more than 27,500 performances by 2018. According to UNESCO's Index Translationum, no individual author has been translated into more languages. Yet the woman behind those numbers spent her early years accumulating rejection letters, failed in her dream of becoming a concert pianist, and once vanished for 11 days, triggering a nationwide manhunt that made the front page of The New York Times. How did a quietly devout, shy woman from Torquay, Devon, become the Queen of Crime? And what did she keep hidden, even from her own autobiography?

• 2. Torquay to the Page

  ›

  Agatha Mary Clarissa Miller was born on the 15th of September 1890 at a villa called Ashfield, in Torquay, Devon. Her father, Frederick Miller, described as "a gentleman of substance", died of pneumonia and chronic kidney disease in November 1901, when Agatha was 11. She later said that loss marked the true end of her childhood.

  Because her siblings were so much older and few children lived nearby, Christie spent much of her time playing alone with pets and imaginary companions. Her mother Clara held an unusual educational philosophy: she believed a child should not learn to read until the age of eight. Christie's own curiosity overrode that plan entirely, and she was reading by four. Her formal schooling came later, including time in Paris at a series of pensionnats focused on voice training and piano. She gave up the ambition of performing professionally when she decided she lacked both the temperament and the talent.

  Her earliest writing followed. At 18, while recovering from illness in bed, she wrote "The House of Beauty", a short story of about 6,000 words dealing with "madness and dreams". Her biographer Janet Morgan called it "compelling" despite "infelicities of style". Magazines rejected every early submission she made, including pieces sent under pseudonyms such as Mac Miller and Sydney West. When she attempted her first novel, Snow Upon the Desert, set in Cairo, all six publishers she contacted declined it. Even the literary agent of family friend and novelist Eden Phillpotts turned it down, though he suggested she try a second book.

• 3. War, Poison, and Poirot

  ›

  On Christmas Eve 1914, Christie married Royal Artillery officer Archibald Christie at Emmanuel Church in Clifton, Bristol, weeks after Britain entered the First World War. While Archie was posted to France, she joined the Voluntary Aid Detachment of the British Red Cross and worked 3,400 hours at the Town Hall Red Cross Hospital in Torquay, first as an unpaid nurse and then, from 1917, as a dispenser earning £16 a year after qualifying as an apothecary's assistant.

  That pharmacy training became the engine of her fiction. As Professor of Pharmacology Michael C. Gerald has observed, in over half her novels one or more victims are poisoned. Arsenic, aconite, strychnine, digitalis, nicotine, and thallium all appear as murder weapons across her career. She brought those skills up to date during the Second World War as well, working in the pharmacy at University College Hospital in London from 1941 to 1947. Her later novel The Pale Horse drew on a suggestion from Harold Davis, the chief pharmacist there; in 1977, British medical personnel used Christie's accurate description of thallium poisoning to solve a real case.

  It was in 1916, still during the First World War, that Christie wrote The Mysterious Affair at Styles. Her detective Hercule Poirot was a former Belgian police officer with "magnificent moustaches" and a head "exactly the shape of an egg", modelled on Belgian refugees she had seen in Torquay and Belgian soldiers she had treated. The manuscript was rejected by Hodder and Stoughton and by Methuen before John Lane at The Bodley Head agreed to publish it in 1920, on the condition that Christie change how the solution was revealed. She complied, but the contract committing her next five books to The Bodley Head was one she later considered exploitative.

• 4. The Eleven Lost Days

  ›

  In August 1926, two things happened in rapid succession: Christie's mother Clarissa died in April, plunging Christie into a deep depression, and her husband Archie told her he had fallen in love with Nancy Neele, a friend of their acquaintance Major Ernest Belcher. On the night of the 3rd of December 1926, after a quarrel at their home in Sunningdale, Christie disappeared.

  The following morning, her Morris Cowley car was found at Newlands Corner in Surrey, parked above a chalk quarry with an expired driving licence and clothes inside. Authorities feared she might have drowned in the Silent Pool, a nearby beauty spot. Home Secretary William Joynson-Hicks pressured police to act; a newspaper offered a £100 reward; more than 1,000 police officers, 15,000 volunteers, and several aeroplanes searched the surrounding countryside. Sir Arthur Conan Doyle gave a spirit medium one of Christie's gloves in an attempt to locate her.

  The day after she vanished, it is now known, Christie had tea in London and visited Harrods, where she was struck by the store's Christmas display. She was found on the 14th of December 1926 at the Swan Hydropathic Hotel in Harrogate, Yorkshire, 184 miles north of Sunningdale, registered under the name "Mrs Tressa Neele" with a South African address. Christie's autobiography makes no mention of any of this. Two doctors diagnosed her with a genuine loss of memory; her biographer Janet Morgan concluded she had been in a fugue state; author Jared Cade argued she had staged the event to embarrass Archie without anticipating the scale of the public reaction. Laura Thompson offered a third reading: that Christie was conscious of her actions but not in emotional control of herself. Public opinion at the time leaned toward a publicity stunt or an attempt to frame her husband for murder.

• 5. Archaeology and a Second Life

  ›

  In 1928, Christie boarded the Orient Express to Istanbul, then travelled on to Baghdad. She had been invited to see the dig led by archaeologist Leonard Woolley and his wife, and on a return visit in February 1930, she met Woolley's assistant, Max Mallowan, 13 years her junior. Mallowan, in a 1977 interview, recalled the day he first took Christie and a group of tourists around his expedition site in Iraq. They married in Edinburgh in September 1930.

  For the rest of her life, Christie spent three to four months a year with Mallowan at excavation sites in Syria and Iraq, including Ur, Nineveh, Tell Brak, and Nimrud. She was not a passive companion. For the 1931 season at Nineveh, she bought a writing table so she could continue her own work. In the early 1950s she paid for a small writing room to be added to the team's house at Nimrud. She photographed and cleaned finds, recorded objects, and restored ceramics, a task she especially enjoyed. She also provided funds for the expeditions.

  That immersion fed her fiction directly. She drew on daily life at a dig for Murder in Mesopotamia and on her knowledge of international train travel for her 1934 novel Murder on the Orient Express. The Pera Palace Hotel in Istanbul, the eastern terminus of the Orient Express railway, claims the book was written there and keeps Christie's room as a memorial. In 1934, she and Mallowan also bought Winterbrook House in the hamlet of Winterbrook near Wallingford, and it became the home where she did most of her writing for the rest of her life.

• 6. The Mousetrap and the Stage

  ›

  When The Mousetrap premiered at the Ambassadors Theatre in the West End on the 25th of November 1952, Christie expected it to run for no more than eight months. Richard Attenborough played Detective Sergeant Trotter in the original cast, with Peter Saunders producing. The play was still running when Christie died in 1976, when she was still running when its 27,500th performance was staged in September 2018, and it ran continuously until March 2020, when all UK theatres closed because of the coronavirus pandemic. It reopened on the 17th of May 2021.

  Christie's arrival as a playwright had come by a different route. In 1928, Michael Morton adapted The Murder of Roger Ackroyd for the stage as Alibi; Christie disliked the changes and resolved to write for the theatre herself. Her first original stage work, Black Coffee, received strong reviews when it opened in the West End in late 1930. A decade later, she became the first female playwright to have three plays running simultaneously in London, with The Mousetrap, Witness for the Prosecution, and Spider's Web all on at the same time. Witness for the Prosecution, whose Broadway production won the New York Drama Critics' Circle award for best foreign play of 1954, also earned Christie an Edgar Award from the Mystery Writers of America.

  She described writing plays as substantially easier than writing novels: "you can see them in your mind's eye, you are not hampered by all that description which clogs you so terribly in a book and stops you from getting on with what's happening." Her daughter Rosalind Hicks holds the copyright to The Mousetrap, and Mathew Prichard, her grandson, inherited the Greenway Estate, which passed to the National Trust after his stepfather's death in 2005.

• 7. After Christie

  ›

  Christie died on the 12th of January 1976 at Winterbrook House at the age of 85. That evening, two West End theatres dimmed their outside lights: the St. Martin's, where The Mousetrap was playing, and the Savoy, which was hosting a revival of Murder at the Vicarage. She was buried at the churchyard of St Mary's in Cholsey, in a plot she had selected with her husband ten years earlier. About 20 reporters attended the funeral, some having travelled from as far away as South America, and 30 wreaths were placed at her grave, including one from the cast of The Mousetrap and one sent on behalf of readers by the Ulverscroft Large Print Book Publishers.

  For tax reasons, Christie had set up a private company, Agatha Christie Limited, in 1955 to hold the rights to her work. In 1968, she sold a 51% stake to Booker Books; by 1977, Booker had increased its holding to 64%. In 1998, Booker sold that stake for £10,000,000 to Chorion, which eventually sold it to Acorn Media UK in 2012. The family's remaining 36% stake passed through Rosalind Hicks to Mathew Prichard and, later, to great-grandson James Prichard, who was the company's chairman in 2020. Agatha Christie Limited still holds worldwide rights to more than 80 novels and short story collections, 19 plays, and nearly 40 television films.

  On the 1st of January 2026, several of Christie's 1930 publications entered the public domain in the United States under the U.S. Copyright Term Extension Act, including the first Miss Marple novel The Murder at the Vicarage and her debut stage play Black Coffee, 95 years after their initial release. In jurisdictions with a copyright term of life of the author plus 70 years, her works will remain protected until 2047.
