What happens
Six weeks after the events at Black Dudley, Abbershaw prepares for his wedding to Meggie but remains haunted by the murder of Colonel Coombe. His suspicions lead him to confront Wyatt Petrie, who confesses to stabbing his uncle, driven by a twisted sense of justice after a girl he loved was ruined by Coombe. Wyatt reveals the flaws in his 'perfect murder' plan, and Abbershaw, torn between law and morality, lets him escape to a monastery in Spain. The chapter ends with Abbershaw receiving a parking ticket from a policeman, which he cheerfully accepts as a sign of order.
