(11 September 1930 - 12 January 1976) (her death)
In 1928, Christie left England for Istanbul and subsequently for Baghdad on the Orient Express. During this trip, she encountered her first archaeological dig and met a young archaeologist, Max Mallowan, whom she married in September 1930. Their marriage was happy and lasted until Christie's death in 1976. In a 1977 interview, Mallowan recounted his first meeting with Christie, wherein he took her and a group of tourists on a tour of his expedition site in Iraq.
Christie frequently used settings that were familiar to her for her stories. She often accompanied Mallowan on his archaeological expeditions, and her travels with him contributed background to several of her novels set in the Middle East. Other novels (such as And Then There Were None) were set in and around Torquay, where she was raised. Christie's 1934 novel Murder on the Orient Express was written in the Pera Palace Hotel in Istanbul, Turkey, the southern terminus of the railway. The hotel maintains Christie's room as a memorial to the author.
Christie lived in Chelsea, first in Cresswell Place and later in Sheffield Terrace. Both properties are now marked by blue plaques. In 1934, she and Max Mallowan purchased Winterbrook House in Winterbrook, a hamlet adjoining the small market town of Wallingford, then within the bounds of Cholsey and in Berkshire.
To honour her many literary works, she was appointed Commander of the Order of the British Empire (CBE) in the 1956 New Year Honours. The next year, she became the President of the Detection Club. In the 1971 New Year Honours, she was promoted to Dame Commander of the Order of the British Empire (DBE). three years after her husband had been knighted for his archaeological work in 1968. They were one of the few married couples where both partners were honoured in their own right. From 1968, owing to her husband's knighthood, Christie could also be styled Lady Mallowan.
