Agatha Christie
in order.

Agatha Christie is the best-selling novelist of all time, with an estimated two billion copies sold — outsold only by the Bible and Shakespeare. Over a career spanning 1920 to 1976, the 'Queen of Crime' wrote 66 detective novels and 14 short story collections, inventing many of the conventions of the modern whodunit and then gleefully breaking them in classics like The Murder of Roger Ackroyd, Murder on the Orient Express, and And Then There Were None, the best-selling mystery novel ever written.

Christie created two of fiction's most beloved detectives: Hercule Poirot, the fastidious Belgian with the 'little grey cells' who stars in more than 35 novels, and Miss Jane Marple, the deceptively sharp spinster of St. Mary Mead. She also wrote the husband-and-wife sleuths Tommy and Tuppence, spy thrillers, and — as Mary Westmacott — six psychological romances. Her play The Mousetrap has run in London's West End since 1952, the longest run of any play in history.

Made a Dame of the British Empire in 1971, Christie remains a global phenomenon decades after her death, with her estate reporting translations into over 100 languages and a steady stream of new film and television adaptations, from David Suchet's definitive Poirot to Kenneth Branagh's star-studded movie trilogy.
