A Question of Integrity (given the title The Wonder Worker in the United States), picks up the story of Nicholas Darrow twenty years after the last of the Starbridge novels. Nick is now rector of a church in the City of London, where he runs a centre for the ministry of healing. His own life is greatly affected by events taking place at the centre, especially after he meets Alice Fletcher, an insecure new worker there, and is forced to reassess his beliefs and commitments as a result.
