Agatha Miller was born in Devon, England, the daughter of an American business man and his English wife. She was married twice, first (from 1914 to 1928) to Colonel Archibald Christie, and then, after a divorce, to the archaeologist Sir Max Mallowan (from 1930 until her death). She had one daughter, Rosalind Christie.
Soon after her first marriage, and during the Great War of 1914-18, Agatha was working in a hospital dispensary and wrote a whodunnit (The Mysterious Affair at Styles) about a poisoning, inventing Hercule Poirot. It was several years before this book was published, but Agatha went on to become the world's best-selling novelist of all time, creating a whole gallery of detectives. She also wrote romantic novels under the name of Mary Westmacott.
