wanted to live in Sunningdale so, in 1924, they moved to a flat called Scotswood, where they lived for two years. At the beginning of 1925, Agatha was invited to participate in a committee to design and organise a children's section of the 1925 British Empire Exhibition in Wembley. Another friend of Belcher's, Nancy Neele, was also invited to be a member of the Committee; Neele would later become Christie's mistress and second wife. The committee on which both Agatha and Nancy sat designed and organised the Children's Paradise section of the Wembley Exhibition which contained Treasure Island as its centrepiece. It was a substantial contribution to the event as The Times outlined its features in-depth and gave the names of the committee. It was a very successful part of the Exhibition as, in the following year, the Treasure Island feature was exported to the United States, where it was lauded as "the greatest amusement feature at the Sesquicentennial Exposition in Philadelphia, Pennsylvania". At the beginning of 1926, Christie and Agatha jointly bought a large house in Sunningdale they called "Styles". In April of that year, Agatha's mother, Clarissa Miller, died, and, for several months, she moved back to her childhood home in Ashfield to sort and pack her mother's belongings. In August, Christie came to see her at Ashfield and told her he wanted a divorce as he had fallen in love with Neele. On 3 December 1926, Agatha left their home in Styles and when she did not return, Archie reported her missing. A major police hunt was undertaken, and Christie was questioned by the police. Agatha was located ten days later at the Swan Hydropathic Hotel (now the Old Swan Hotel) in Harrogate, Yorkshire, registered as Mrs Teresa Neele. Christie was asked to go to the hotel to identify his wife. She apparently did not recognise him until later, when she was recovering at her sister's house, Abney Hall. Christie issued a statement to the press saying that his wife was suffering from a nervous disorder and that she had complete loss of memory. The 1979 dramatic film Agatha was based on this event with Agatha and Archie portrayed by Vanessa Redgrave and Timothy Dalton. After this, the couple separated. Agatha went to live in a flat in London, and Christie remained at Styles so that he could sell it. In 1928, Christie married Nancy Neele at
