Black Coffee

Agatha Christie is the most widely published author of all time in any language. Now, in this never before published story, her most famous and beloved detective, Hercule Poirot, returns to bring his "little gray cells" to bear on one last case. In the spring of 1934, Poirot is summoned to Surrey, by England's most prominent physicist, Sir Claud Amory. Amory fears that someone in his household is attempting to steal his latest discovery, a formula critical to England's defense. Poirot, with Captain Hastings at his side, rushed to Surrey, but arrives too late. Amory has died, his formula is missing, and anyone in his country house, full of relatives and guests, could have been responsible. Originally written in 1930 as a three-act play, Black Coffee is adapted as a novel by Charles Osborne (Christie's biographer and well-known theater and opera critic). Black Coffee is classic Christie at her finest.
