Agatha Christie

Agatha Christie was born Agatha Mary Clarissa Miller in Torquay, Devon, on 15 September 1890. Her mother, Clara, encouraged her imaginative childhood games, while her American father, Frederick Miller, died when Christie was eleven. During the First World War, she trained as a dispenser at a hospital in Torquay and worked with medicines, an experience that gave her practical knowledge of poisons. She began writing detective fiction before the war, and her first published novel, *The Mysterious Affair at Styles*, appeared in 1920. It introduced Hercule Poirot, the Belgian refugee detective whose precise reasoning and distinctive appearance made him one of fiction’s best-known investigators.

Christie’s second major detective, Miss Jane Marple, first appeared in *The Murder at the Vicarage* in 1930. An elderly resident of the village of St Mary Mead, Miss Marple solves crimes through sharp observation and comparisons with human behavior she has encountered locally. Christie’s novels often depend on carefully controlled clues, misleading testimony, concealed identities, and final revelations that reconstruct the crime for the reader.

In 1926, Christie’s first marriage, to Archibald Christie, ended after he asked for a divorce. That December, she disappeared for eleven days, prompting a large search and extensive newspaper coverage. She was found at a hotel in Harrogate, where she had registered under the surname of her husband’s mistress. Christie later married archaeologist Max Mallowan in 1930. Her travels with him in the Middle East influenced novels including *Murder on the Orient Express*, published in 1934, and *Death on the Nile*, published in 1937.

During the Second World War, Christie worked in a hospital dispensary and continued writing. Her 1939 novel *And Then There Were None*, originally published under a different title, places ten people on an isolated island and removes them one by one according to the pattern of a nursery rhyme. Her stage play *The Mousetrap* opened in London in 1952 and became the world’s longest-running theatrical production, continuing for decades.

Christie also wrote romantic fiction under the pseudonym Mary Westmacott, including *Absent in the Spring*. She received a Commander of the Order of the British Empire in 1956 and became President of the Detection Club. Christie died on 12 January 1976 at Winterbrook House near Wallingford, Oxfordshire. Her books remain widely translated and continue to shape detective fiction through their emphasis on fair-play clues, ingenious construction, and psychologically deceptive suspects.
