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.
