The name "Agatha Christie" is nearly synonymous with upper-class British mysteries, for good reason. Christie (1890-1976) set the standard for the genre in more than 60 novels and dozens of short stories, creating two iconic detectives along the way: the fastidious Belgian Hercule Poirot, and the English spinster Jane Marple in the Miss Marple series. No one could match her knack for weaving clues into her stories. Widely considered her masterpiece, And Then There Were None has been adapted into a number of films.
