Black Coffee is a play by the British crime-fiction author Agatha Christie (1890–1976) which was produced initially in 1930. The first piece that Christie wrote for the stage, it launched a successful second career for her as a playwright. Twenty-two years after Christie's death, Black Coffee was re-published in the United Kingdom and the United States in the form of a novel. The novelisation was undertaken by the Australian-born writer and classical music critic Charles Osborne, with the endorsement of the Christie estate.
