Plot

Jackson finally solves the mystery of Laura's killer whilst Shirley, about to make a wealthy marriage, tells him that she feels guilty because she promised to look after Tanya, the daughter of her sister Michelle who was sent to prison for murdering her husband. Tanya went off the rails on discharge from a care home and Shirley wants to make amends. A meeting with Michelle however paints a different picture and Jackson is convinced that Shirley only wants Tanya found so that she does not ruin the marriage. Fortunately a happy coincidence brings closure for Tanya and Theo whilst the Lands' eldest sister, now a nun, throws light on the fate of Olivia. Jackson, however, is perturbed to learn that his ex-wife is leaving, with their daughter, for a job in New Zealand.—don @ minifie-1

Brodie learns that there is a fourth Land sister, Sylvia, who is now a nun and has been since not long after Olivia's death 30 years ago. He also learns that the girls' father sexually abused them, or at least attempted to do so. The reaction of a former police colleague to seeing Blue Mouse leads him to identify the killer. In the case of Laura Wyre, he is convinced she was involved with someone but was afraid that her father would find out. He first suspects one of Laura's teachers but the answer lies elsewhere. As for Shirley Manning and her missing niece Tanya, he learns the truth about what happened to Tanya's father.—garykmcd
