Dame Agatha Mary Clarissa Christie (colloquially regarded as "The Queen of Crime"), was an English writer known for her 66 detective novels and 14 short story collections, particularly those revolving around her fictional detectives Hercule Poirot and Miss Marple. She is the writer of the mystery novel And Then There Were None.


Christie was born on 15 September 1890, into a wealthy upper middle-class family in Torquay, Devon.

Christie was made a dame in 1971 by Queen Elizabeth II. Throughout her life she was surrounded by strong women and she was Christian, although she believed in psychic powers.

She was also homeschooled, which isolated her from society and allowed her to explore her creative side.

Her father was often ill and died when she was a teenager.

Her marriage ended in divorce and afterwards she disappeared for ten full days.

And Then There Were None

And Then There Were None was first published in the United Kingdom by the Collins Crime Club on 6 November 1939, as "Ten Little Niggers".

The title has changed several times with different editions, including: "Ten Little Indians" and "And Then There Were None".

It is Christie's best-selling novel, with more than 100 million copies sold; it is also the world's best-selling mystery and one of the best-selling books of all time. Publications International lists the novel as the sixth best-selling title.
