Christie's first published novel, a classic country house mystery. Captain Hastings, recovering from war wounds, is invited to stay at Styles Court, the Essex home of a wealthy elderly woman and her large, quarrelsome household. When a crime shakes the house, Hastings turns to his old friend Hercule Poirot, a Belgian refugee living nearby. Poirot begins to sift through small details, family tensions and conflicting accounts. The book introduces the fussy, brilliant detective and his admiring companion, and it set out the pattern of clues and suspects that Christie would refine for decades.
