Agatha Mary Clarissa, Lady Mallowan, DBE (15 September 1890 – 12 January 1976), mainly known as Agatha Christie, was an English crime fiction writer. She also wrote romances under the name Mary Westmacott, but is chiefly remembered for her 66 detective novels. Her work with these novels, particularly featuring detectives Hercule Poirot or Miss Jane Marple, have given her the title the 'Queen of Crime' and made her one of the most important and innovative writers in the development of the genre.
Christie has been called—by the Guinness Book of World Records, among others—the best-selling writer of books of all time, and the best-selling writer of any kind second only to William Shakespeare. An estimated one billion copies of her novels have been sold in English, and another billion in 103 other languages.

Biography
Agatha Christie's first novel The Mysterious Affair at Styles was published in 1920 and introduced the long-running character detective Hercule Poirot, who appeared in 30 of Christie's novels and 50 short stories.
Her other well known character, Miss Marple, was introduced in The Murder at the Vicarage in 1930, and was based on Christie's grandmother.
During World War II, Christie wrote two novels intended as the last cases of these two great detectives, Hercule Poirot and Jane Marple—respectively, Curtain, in which Poirot is killed, and Sleeping Murder. Both books were sealed in a bank vault for over thirty years, and were released for publication by Christie only at the end of her life, when she realised that she could not write any more novels. These publications came on the heels of the success of the film version of Murder on the Orient Express in 1974.
Like Arthur Conan Doyle, Christie was to become increasingly tired of her detective, Poirot. In fact, by the end of the 1930s, Christie confided to her diary that she was finding Poirot "insufferable", and by the 1960s she felt that he was an "an ego-centric creep". However, unlike Conan Doyle, Christie resisted the temptation to kill her detective off while he was still popular. She saw herself as an entertainer whose job was to produce what the public liked, and what the public liked was Poirot.
In contrast, Christie was fond of Miss Marple. However it is interesting to note that the Belgian detective's titles outnumber the Marple titles by more than two to one.
Poirot is the only fictional character to have been given an obituary in The New York Times, following the publication of Curtain in 1975.
Following the great success of Curtain, Christie gave permission for the release of Sleeping Murder sometime in 1976, but died in January 1976 before the book could be released. This may explain some of the inconsistencies in the book with the rest of the Marple series—for example, Colonel Arthur Bantry, husband of Miss Marple's friend, Dolly, is still alive and well in Sleeping Murder (which, like Curtain, was written in the 1940s) despite the fact he is noted as having died in books that were written after but published before the posthumous release of Sleeping Murder in 1976—such as, The Mirror Crack'd from Side to Side. It may be that Christie simply did not have time to revise the manuscript before she died. Miss Marple fared better than Poirot, since after solving the mystery in Sleeping Murder, she returns home to her regular life in Saint Mary Mead.
On an edition of Desert Island Discs in 2007, Brian Aldiss recounted how Agatha Christie told him that she wrote her books up to the last chapter, and then decided who the most unlikely suspect was. She would then go back and make the necessary changes to "frame" that person. [2]

Hercule Poirot & Miss Marple
On 10 August 2007, it was announced that Christie, played by actress Fenella Woolgar, would appear as a character in the 2008 season of the science fiction TV series Doctor Who.
