Their relationship was beginning to be strained--some part had to be blamed on the game of golf. Agatha began to be troubled by Archie's love for golf, so much so that Agatha felt he was more interested in it than he was in his own family. She had to get away for a little, so she went to Corsica without him. When she returned, she received news that her mother Clara was gravely ill with bronchitis. She passed away shortly after but Archie didn't want anything to do with it. Agatha described him as someone who hated "illness, death, and trouble." His solution for Clara's passing was for everyone to go to Spain. Agatha refused to leave and Archie stayed in London.
More than a month later, he announced that he was in love with another woman, and demanded a quick divorce. The woman was Nancy Neele, the former secretary of Major Belcher. After a small separation, he returned to Agatha and Rosalind for reconciliation. This was an utter failure and Agatha described it as "a mistake". Archie announced in December of 1926 that he decided to finally leave Agatha and marry Miss Neele. Archie packed his bags and left for a friend's house, where Miss Neele was waiting for an engagement party. That same day, December 4 (many sources say the 3rd or even the 8th), was when Agatha totally broke down and disappeared. After the ordeal of Agatha's disappearance, Archie left Styles for good. Christie said this about the entire episode and about Archie: "So, after illness, came sorrow, despair, and heartbreak. There is no need to dwell on it. I stood out for a year, hoping he would change. But he did not. So ended my first married life." Agatha and Archie were divorced in April of 1928. Archie did marry Nancy Neele at St. George's Church in Hanover Square (London), and remained married until she died in 1959. Archie Christie died in 1962.
