Agatha Christie and her husband Max are buried at St Mary's Church, Cholsey, Berkshire.
Agatha Christie was appointed a Fellow of the Royal Society of Literature in 1950. She received an honorary degree (Doctor of Letters) from the University of Exeter in 1961.
From the 1930s until her death, Agatha Christie had two country houses, Winterbrook House, near Wallingford, Berkshire, bought in 1934, and Greenway House in Devon, with about two hundred and fifty acres, bought in 1938. The house in Devon is still owned by her daughter and grandson.
Christie's work has built a huge fortune for her family: her daughter and grandson are said to be worth more than six hundred million pounds sterling, or well over a billion U.S. dollars.
Agatha's play The Mousetrap is now the longest continuously-running stage production in history, having opened in 1952.
Under her own name, Agatha wrote seventy-eight thrillers, nineteen plays, two autobiographies, one book for children, and over a hundred short stories. As Mary Westmacott, she also published six romantic novels.
Agatha met her second husband, the archaeologist Max Mallowan, while he was digging at Ur in what is now Iraq. He was a Fellow of All Souls College, Oxford, and fourteen years younger than Agatha.
In December 1926, Agatha crashed her car in Berkshire and vanished without trace. She was missing for eleven days, causing a sensation. Her husband was suspected of murder, but then Agatha was found alive and well staying in Harrogate under the name of her husband's mistress. Archie and Agatha soon separated. Her family claimed it was a case of amnesia, but the episode remains a mystery.
Agatha had only one child, Rosalind Christie, born in 1919. Rosalind also had one child, Matthew Pritchard, born in 1943, who now controls his grandmother's literary estate.
During the first world war, Agatha worked in a hospital dispensary. When some arsenic was stolen, it gave her the idea for her first book, The Mysterious Affair at Styles, and Hercule Poirot was born.
At the age of nineteen, Agatha got engaged to Major Reginald Lucy, of the Royal Artillery. However, in 1914 she married Archie Christie, an officer in the Royal Field Artillery. In 1928, they got divorced, and in 1930 Agatha married Max Mallowan (later Sir Max), an archaeologist.
Agatha's father, Frederick Alvah Miller, was an American business man living in England, while her mother Clarissa (Clara) Boehmer was born in Ireland.
When Agatha was eleven, her father died and she struck up a friendship with the novelist Eden Phillpotts, who lived near her mother's house in Devon.
Agatha and her sister did not go to school - instead, they had tutors at home. At the age of seventeen, Agatha went for a year to a 'finishing school' in Paris.
She grew up on the outskirts of the seaside town of Torquay, in Devon.
Agatha was the youngest of three children. Her sister Margaret (Madge) was twelve years older than agatha and her brother Louis Montant (Monty) was ten years older.
Christie was named a Dame of the Order of the British Empire in 1971.
Agatha Christie's books have been translated into more than 100 languages.
Estimates state that nearly two billion copies of Agatha Christie books have been printed.
