On the night of Friday 3 December 1926, Agatha Christie left her home in Sunningdale, Berkshire, and drove off into the dark. The next morning her car was found abandoned at Newlands Corner, near Guildford, with a fur coat and her driving licence inside. The Agatha Christie disappearance had begun.
For 11 days, she was missing. Police searched the Surrey Downs, a newspaper offered £100 for news of her, and two of her fellow crime writers were drawn into the hunt. Then, on 14 December, she turned up at a hotel in Harrogate, about 200 miles from home, registered under the surname of her husband’s mistress. A century on, nobody can say for certain why she went.
So we opened the file. Going back to the 1927 police letter at The National Archives, the Hansard record and what her biographers have argued since, we found a medium holding her glove, a hotel that still hosts crime writers every July, three different stories about who spotted her, and a search that cost either £25 or £12 10s, depending on who you asked.
Exhibit A
What happened when Agatha Christie went missing?
RealShe left home on 3 December 1926, her empty car was found the next morning, and she was found 11 days later at a hotel in Harrogate.
- 3 Dec
After a quarrel, her husband Archie leaves for a weekend with his lover. That night, Agatha leaves home too.
- 4 Dec
Her car is found at Newlands Corner, near Guildford, with a fur coat and her driving licence inside.
- 9 Dec
Police and volunteers mount another wide search of the Downs around Newlands Corner.
- 14 Dec
She is recognised at a Harrogate hotel, and Archie travels north to identify her.
The fullest official account is a letter from Surrey Constabulary’s deputy chief constable, William Kenward, to the Home Office, dated 9 February 1927 and now held by The National Archives. It says police and volunteers searched the Downs around Newlands Corner on 4, 5 and 6 December, before about three dozen officers were brought in for a wider search.
The same letter records a witness who said he had helped a woman matching her description start a car at 6.20 am, and that she was “sparsely dressed for such an inclement morning”. Kenward also complained that the press had exaggerated how many police were involved. Searchers even dredged the nearby Silent Pool, Historic UK says.
Exhibit B
Which crime writers joined the search for Agatha Christie?
RealTwo of the biggest names in detective fiction: Arthur Conan Doyle and Dorothy L. Sayers.
Conan Doyle, the creator of Sherlock Holmes, had a strong interest in the occult. He took one of Christie’s gloves to a medium in the hope it would lead to her, Historic UK says. Countryfile says the medium didn’t find her.
Dorothy L. Sayers, the creator of Lord Peter Wimsey, went to the scene too, and later used it in her novel Unnatural Death, the Ripon Gazette says.

Which Harrogate hotel did Agatha Christie stay in?
RealThe Swan Hydropathic Hotel, now the Old Swan Hotel. She checked in as Mrs Teresa Neele from Cape Town.
It was a spa hotel at the time, known locally as the Hydro, and it had been renamed the Old Swan Hotel by the mid-1950s, according to Wikipedia’s history of the hotel. The details of her registration, Mrs Teresa Neele of Cape Town, come from The Spectator.
The hotel has never really left the story. The 1979 film Agatha, starring Vanessa Redgrave and Dustin Hoffman, was filmed there. The Theakston Old Peculier Crime Writing Festival is held there each July, and the 2026 festival marked 100 years since Christie’s disappearance, Crime Fiction Lover reported.
Exhibit D
Who recognised Agatha Christie at the hotel?
DisputedAccounts differ. The National Archives says a member of the public recognised her on 14 December.

| Historic UK | The head waiter |
| WikipediaCiting her biographers | Two hotel band players |
When Archie arrived that evening, she was reading a newspaper report of her own disappearance, Historic UK says, and witnesses noticed she showed little sign of recognising him.
Exhibit E
Who was Nancy Neele?
RealArchie Christie’s lover, and the woman whose surname Agatha used at the hotel.
Archie had asked Agatha for a divorce a few months before she vanished, according to the Surrey Police and Crime Commissioner, and her mother had died earlier that year. On 3 December, after a quarrel, he left their home, Styles, to spend the weekend with Nancy Neele in Godalming, the Ripon Gazette says.
The couple divorced in 1928, and Archie went on to marry Nancy, according to Wikipedia’s account of the disappearance.
Exhibit F
Why did Agatha Christie disappear?
UnsolvedNobody knows for certain. Her family said she had lost her memory, but the theories have multiplied ever since.
Here is the line-up.
Theory 1
Lost memory
The case: The official version. Archie said she had lost her memory, and two doctors backed him, Historic UK says.
But: Biographer Laura Thompson rejects it, arguing nobody recovers from amnesia like that within two weeks.
Theory 2
A fugue state
The case: Historian Lucy Worsley argues it was a mental health crisis, a “fugue state” in which a person carries on with ordinary life but can’t say who they are.
Also: The psychologist Andrew Norman reached a similar conclusion.
Theory 3
A breakdown
The case: Thompson sees a breakdown brought on by her mother’s death and her husband’s betrayal landing at the same time.
Theory 4
A publicity stunt
The case: Cynics said she vanished to sell books, the Surrey Police and Crime Commissioner notes.
But: Worsley rejects it, and so did biographer Janet Morgan.
Theory 5
Framing Archie
The case: One theory at the time was foul play by her husband, the Surrey Police and Crime Commissioner notes. Another is that she vanished to cast suspicion on him.
But: Worsley rejects the idea of a plot to frame him.
Exhibit G
How much did the search for Agatha Christie cost?
DisputedAbout £25, according to Surrey police. The Home Secretary told MPs it was half that.
In his letter of 9 February 1927, Kenward put the cost at about £25, mainly for hiring vehicles and refreshments for special constables. Archie Christie declined to contribute, calling it “entirely a police matter”, The National Archives says.
The next day, the Home Secretary, Sir William Joynson-Hicks, told the Commons the search had cost “about £12 10s. 0d.”, and that he believed this included police wages, according to Hansard.
The newspapers spent more. The Daily News offered £100, over £5,000 in today’s money, to any reader who could find her, Countryfile says.
Exhibit H
Did Agatha Christie ever explain her disappearance?
BarelyHer autobiography leaves it out, but she gave an account to the Daily Mail in 1928.
Her autobiography says nothing directly about the 11 days, mentioning only a period of grief and a broken heart, according to Wikipedia’s summary of her biographers.
In a 2025 piece, Lucy Worsley argues that the 1928 interview describes a mental health crisis, and that the press, attitudes to women and the stigma around shell shock stopped people taking that explanation seriously at the time.
On 3 December 2026, it will be 100 years since she left Styles. The question of what she was thinking that night is still open.
