AGATHA CHRISTIE is the world's best known mystery writer. Her books have sold over a billion copies in the English language and another billion in 44 foreign languages. She is the most widely published author of all time in any language, outsold only by the Bible and Shakespeare.

Her writing career spanned more than half a century, during which she wrote 80 novels and short story collections, as well as 14 plays, one of which, The Mousetrap, is the longest-running play in history. Two of the characters she created, the brilliant little Belgian Hercule Poirot and the irrepressible and relentless Miss Marple, went on to become world-famous detectives. Both have been widely dramatized in feature films and made-for-TV movies.

Agatha Christie also wrote under the pseudonym Mary Westmacott. As well, she wrote four non-fiction books including an autobiography and an entertaining account of the many expeditions she shared with her archaeologist husband, Sir Max Mallowan.

Nine short mysteries feature sleuths Miss Marple and Hercule Poirot, in a collection whose title story finds the guests of Monkswell Manor trapped inside by a snowstorm while a killer is on the loose. Reissue.
