By the Pricking of My Thumbs

Born in Torquay in 1890, Agatha Christie began writing during the First World War and wrote over 100 novels, plays and short story collections. She was still writing to great acclaim until her death, and her books have now sold over a billion copies in English and another billion in over 100 foreign languages. Yet Agatha Christie was always a very private person, and though Hercule Poirot and Miss Marple became household names, the Queen of Crime was a complete enigma to all but her closest friends.
