The Comforters
by Muriel Spark
Caroline Rose is plagued by the tapping of typewriter keys and the strange, detached narration of her every thought and action. Caroline has an unusual problem - she realises she is in a novel. Her fellow characters also seem deluded: Laurence, her former lover, finds diamonds in a loaf of bread - has his elderly grandmother hidden them there? And Baron Stock, her bookseller friend, believes he is on the trail of England's leading Satanist.
