Agatha Clarisse Miller was born in 1890. At the age of 24, she married Archibald Christie, an aviator of the Royal Flying Corps while working as a nurse in a hospital.

A year after her marriage, she published her first novel, the first of a long series of which Death on the Nile , The Crime of the Orient-Express or The 10 Little Negroes . At the time of her disappearance, the novelist had written a few novels but had not yet acceded to the celebrity. During these mysterious days, everyone will be passionate about his fate.

On December 3, 1926, Agatha Christie disappeared at the age of 36 years. Around 10 pm, while her husband is at his mistress's weekend, the novelist leaves his daughter Rosalind and announces to her secretary that she is going out. The next day, one finds his car in the countryside without any trace of the driver.

Her husband, Archibald Christie (hero of the Great War), will even be suspected of having murdered her. A theory supported by the servants who would have heard a dispute in the day, especially since Agatha Christie had just discovered the adultery of her husband.

The press makes the disappearance of the novelist public and the Daily News goes so far as to offer a reward to the person who will bring elements on the investigation. A few days later, the investigation obtained no results and had only three clues: written messages on paper, one of which had been destroyed by her husband and another revealing that she had gone to rest in a Yorkshire spa.

Eleven days after the disappearance of Agatha Christie, the police received an alert: they would have seen it in a Yorkshire hotel, come under a false name. The most astonishing in history: her false name is the name of her husband's mistress.

A few days later, the novelist returns to London and will never evoke those days of which only she will hold the truth. To avoid the subject the times when he was asked to express himself, Agatha Christie will evoke a sudden amnesia. She even said that she had told everything to her secretary, but the soundtrack would have been inaudible.

The story is so intriguing that a novel ( Agatha Christie, the missing chapter ) will try to imagine the case, even to elucidate it, because even in his autobiography, Agatha Christie will not talk about his disappearance. The mystery remains whole and transforms the novelist into a marginal woman. Some think of a simple publicity shot to make her talk or a vengeance against her husband who deceived her a lot when others consider a kidnapping or a real secret that her biggest fans would like to know ...

Eventually, we finally think that the one we called the Queen of Crime wished to write a police novel with her as a heroine to live in real way one of her scenarios. One thing is certain: this disappearance marks a turning point in the life of author of Agatha Christie.
