It has been more than a year since Cannon Whyte fell 103 feet from the cathedral gallery, yet unease still casts a shadow over the peaceful lives of the Close's inhabitants. In an apparently separate incident, head verger Appledown is being persecuted: a spate of anonymous letters and random acts of vandalism imply that he is inefficient and immoral. But then the notes turn threatening, and when Appledown is found dead, Inspector Hazelrigg is called in. Investigations suggest that someone directly connected to the cathedral is responsible, and it is up to Hazelrigg to get to the heart of the corruption.
