Summary With definitive proof that Jason Buliegh could not have committed the murder of Angela Fairley, Joe and Chrissie begin to rationalize what they have done. Buliegh's solicitor, who happens to be Chrissie's sister, issues an appeal for anyone who might have seen him. The squad begins to focus on other suspects, including a drug dealer who lived on the same estate and the dead girl's parents. A problem arises when Chrissie's father, a retired former policeman suffering from dementia, begins to remember some of the events on the fateful evening. Chrissie ingratiates himself with Buliegh's mother in the hope that he will be the first to get any information she might acquire. DS Lucy Romanis has been so busy on the case that she has done no work on the case of an elderly man who was beaten by three youths.
