On 3rd December 1926, Agatha Christie fought with her husband, Archibald. He had been having an affair which Christie had discovered; she had also been informed he was planning to spend the weekend with friends and his mistress.
Once he had left, she went upstairs and kissed her daughter, Rosalind (7), goodnight. Getting into her Morris Cowley, she left the house. What ensued was one of the biggest manhunts in history. In a mystery more connected to her books, Christie was not found again until eleven days later.
