During her career, Agatha wrote and published her novels in a timely manner but when tasked with writing her autobiography it took 15 years to write and it was published after her death. Even in her autobiography, she maintained her privacy and withheld the details related to her disappearance.
In her autobiography Agatha refused to discuss the details surrounding her disappearance; she briefly describes life as unbearable “from that time [onward] I suppose dates my revulsion against the press, my dislike of journalists, and of crowds” (Christie, 1977). Most of the knowledge surrounding her disappearance comes from police reports, news articles, and interviews that individuals gave to the media. The mystery related to her mental state during her disappearance persists and the public will never definitively know what Agatha was thinking or experiencing emotionally at the time. “The clues to her personality and influences can be found in her novels; other clues are buried in her life story, her letters, and the memories she chose to share in her autobiography” (Corrigan, 2021). Archie Christie, family members, close friends, and her secretary all maintained that Agatha suffered from amnesia during the time in question. While performing research for an autobiography being written about Agatha, biographer Laura Thompson had access to Agatha’s personal affects which included notebooks, papers, and letters. In the biography, Thompson quotes a Chinese proverb found amongst these personal affects “of the 36 ways of avoiding disaster running away is the best” (Thompson, 2020).
