Almost a century after Agatha Christie disappeared, fans still speculate about why she vanished.

Christie wrote more than 80 books during her career, many featuring detective Hercule Poirot and Miss Marples. Famously, the Queen of Crime mysteriously vanished on Dec. 3, 1926, after a fight with her husband, Colonel Archibald “Archie” Christie. He had asked her for a divorce months earlier as he was having an affair with a younger woman named Nancy Neele.

Following the row, the Seven Dials author packed a small suitcase, drove her car into the night and disappeared. Her vehicle was found the following day above a chalk quarry and a manhunt ensued. The theories of what happened to the famed writer ranged from suicide to her husband’s involvement to Christie hiding out in London in men’s clothing.

It would be 11 days before Christie turned up at a Yorkshire spa on Dec. 15, which she had checked into under the last name Neele. At the time, Christie, her husband and several doctors said that amnesia was to blame, but the truth behind why she disappeared and what occurred in that time remain a mystery to this day.

Here’s everything to know about Agatha Christie’s disappearance.

When did Agatha Christie disappear?

Christie, then 36, disappeared on the night of Dec. 3, 1926. Her mother had died that April and her husband had asked for a divorce in August. At the time, she had moderate literary success, having released six novels in six years, including 1925’s The Murder of Roger Ackroyd.

Around 9:45 p.m., the British writer gave her sleeping 7-year-old daughter, Rosalind, a goodnight kiss, got into her green Morris Cowley roadster and left her home in Berkshire, England. She had packed a small suitcase, her driver’s license, a photo of her daughter and cash.

The next day, Christie’s car was discovered abandoned above a chalk quarry in Newlands Corner. Some of her clothes, including a fur coat, her license and a bottle labeled “poison lead and opium” were allegedly found nearby.

“The novelist’s car was found abandoned near Guildford on the edge of a chalk pit, the front wheels actually overhanging the edge,” The New York Times reported on Dec. 6. “The car evidently had run away, and only a thick hedge-growth prevented it from plunging into the pit.”

Who was Agatha Christie married to at the time of her disappearance?

Christie married Colonel Archibald “Archie” Christie in 1914, and the pair shared one daughter, Rosalind Margaret Clarissa Hicks (née Christie), born in August 1919. Hicks would go on to run her mother’s estate before she died in 2004 at the age of 85.

At the time of Christie's disappearance Archie, a former World War I pilot, was having an affair with a younger woman named Nancy Neele and wanted a divorce. He and Christie got into a fight on Dec. 3, and he left their home to spend the weekend with friends, including Neele. Christie vanished later that night.

The author and the war veteran divorced in 1928. Christie married her second husband, Sir Max Mallowan, in 1930.

What was the search for Agatha Christie like?

The sudden vanishing of a famous writer made front-page news around the world.

The New York Times reported that 100 policemen searched for her over that first weekend. Police initially called off the search on Dec. 8 after Christie’s brother-in-law informed them that he had received a letter that Christie was going “for rest and treatment” at a Yorkshire spa.

The letter was apparently unconvincing, and the search began again, with detectives presuming suicide. The hypothesis grew legs because Christie’s car was found near a natural spring where some theorized she may have drowned. At points, Archie was also considered a suspect, but he had an alibi.

In total, Christie appeared to have written four letters: to her secretary, noting that she would not be returning that evening; to her brother-in-law; to her best friend, Charlotte, which was given to the police and read that Christie needed to “get away from here” because “it just wasn’t fair;" and to her husband, who would not reveal the contents of his, which he reportedly read then destroyed, per National Geographic.

A week in, the manhunt continued, with more than 10,000 volunteers looking for Christie, along with dozens of dogs. To try and help solve the mystery, author Sir Arthur Conan Doyle even consulted a medium, providing her with one of Christie’s gloves.

Among the primary speculations made by police was that Christie may have run off to London and disguised herself in men’s clothes. They did not believe she was planning on returning home.

Where did Agatha Christie disappear to?

The novelist was found on Dec. 15, 1926, at the Swan Hydropathic Hotel in Yorkshire (now called the Old Swan Hotel), more than 200 miles from her home.

Christie had checked in under the moniker “Teresa Neele.” The last name was that of Archie’s girlfriend, whom he married after his divorce from Christie.

After the Murder Is Announced writer was located, the explanation for her disappearance was reported as amnesia.

“She does not know who she is ... she has suffered from the most complete loss of memory,” Archie told reporters, according to The New York Times.

The why behind Christie’s disappearance is, well, still a mystery. One theory is that she was distraught about Archie’s affair and sought revenge, which was why she used the name “Neele” at the spa.

The party Archie attended the weekend of his wife’s disappearance was actually his engagement party to Neele — though he didn’t tell the police that when questioned. Christie’s return in under two weeks meant that Archie had to return to her side and publicly pretend their marriage was doing just fine, according to National Geographic.

Another theory is that Christie had been contemplating suicide, though she later said she had not attempted it.

Her biographer Janet P. Morgan wrote that Christie had been in an “hysterical fugue” state, in which a person experiencing extreme stress can forget their identity. In 2006, writer Andrew Norman, a former doctor who wrote the 2007 book Agatha Christie: The Finished Portrait, told The Guardian that he believed Christie was suicidal and “had fallen into a psychogenic amnesia after a period of depression.”

Others think the disappearance was a publicity stunt. “My wife had discussed the possibility of disappearing at will ... engineering a disappearance had been running through her mind, probably for the purpose of her work,” Archie told The Daily Mail.

Did Agatha Christie’s disappearance mimic her books?

Christie’s disappearance doesn’t exactly match the plot of any of her stories, but there was plenty of source material in her books that was similar to her vanishing.

In The Murder of Roger Ackroyd, published not long before she disappeared, the narrator was the murderer all along. The book also makes use of ellipses, alluding to forgetting or skipping periods of time.

Christie later wrote a semi-autobiographical novel called Unfinished Portrait under her pen name, Mary Westmacott. The book follows Celia, who is in the middle of a divorce and considering suicide; some believe it reflects Christie’s mindset at the time of her disappearance and dissolving marriage.

Did Agatha Christie ever discuss her disappearance?

In 1928, Christie provided some details about her nearly two-week disappearance during an interview with The Daily Mail.

She told the outlet that she had driven past a quarry on Dec. 3 and it “came into my mind the thought of driving into it,” but she “dismissed the idea at once” because her daughter was in the car with her.

“That night I felt terribly miserable. I felt that I could go on no longer. I left home that night in a state of high nervous strain with the intention of doing something desperate,” she told the outlet. “When I reached a point on the road which I thought was near the quarry, I turned the car off the road down the hill toward it. I left the wheel and let the car run. The car struck something with a jerk and pulled up suddenly. I was flung against the steering wheel, and my head hit something. Up to this moment I was Mrs. Christie.”

Christie did not speak publicly about the incident again. In her memoir, Agatha Christie: An Autobiography, she wrote, “For the first time in my life I was really ill,” and noted that her forgetfulness, tears and insomnia marked “the beginning of a nervous breakdown.”

She did not elaborate further, and of the end of her marriage, she only wrote, “There is no need to dwell on it. I stood out for a year, hoping that he would change. But he did not. So ended my first married life.”

The Guardian reported in 2004 that Christie wasn’t able to talk to her daughter about the incident, which was tough on Rosalind.

Nearly a century later, the cause of Christie’s disappearance is still widely debated, and biographies about Christie have not provided any more information about the incident.

Hollywood has long been fascinated with Christie’s disappearance. The 1979 film Agatha, starring Dustin Huffman and Vanessa Redgrave, a 2008 episode of Dr. Who and a 2018 British TV movie called Agatha and the Truth of Murder are among the many works that speculate about what happened when Christie vanished.

Novels have also been written about it, including Kathleen Tynan’s Agatha (1977), Andrew Wilson’s A Talent for Murder (2017), Marie Benedict’s The Mystery of Mrs. Christie (2022) and 2022’s The Christie Affair, in which Nina de Gramont reimagines the author’s disappearance and tells the story from the perspective of the mistress, here named “Nan O’Dea.”

“The detail that made me want to write a novel about it — that sort of made a story start to come into shape — was that she had used the last name of her husband’s mistress to register at the hotel,” Gramont told The New York Times in 2022.
