Now in their mid-40s, Amelia and sister Julia return to their father Victor's house to care for him in his final days and then organise his funeral.

The second case involves Theo, a morbidly obese, middle-aged man who is unable to move on from his beloved daughter Laura's seemingly random murder in 1994.

She was 18 and had just began working as an assistant at Theo's law practice for the summer when a mysterious man in a yellow golfing vest came into the building and fatally stabbed her.

Michelle, who may have already had psychopathic tendencies as a result of a dysfunctional upbringing, had also been under extreme stress, only being eighteen years old with a new baby, Tanya, whom she had no attachment to, while living without many basic utilities (such as hot water) in an isolated, rural area.

She later changed her legal name to Caroline and moved to a remote village where she currently works as headmistress for the local primary school, but otherwise has to live a secretive existence.

However, after combing through every one of Theo's ex-client folders (mostly women fleeing domestic abuse), Jackson is unable to find anyone whose partners may have held a grudge against him.

Throughout this distressing time, Theo finds some paternal comfort in giving money to a young homeless woman, Lily-Rose, whom he walks past each day, and interacting with Jackson's eight-year-old daughter Marlee, who has to accompany him at work.

Meanwhile, Jackson and Marlee visit Sylvia in the convent and present Blue Mouse to her, but she insists she still has no idea what happened that night.

Jackson's personal life begins to deteriorate as his work on the cases continues; he's attacked, seemingly at random, someone drains the brake fluid from his car, and he feels he is being followed.

While returning from a visit to Laura's grave, Theo has a bad asthma attack and is narrowly saved from dying by Julia and Lily-Rose who had alerted her, and he is taken to hospital.

Sylvia finally discloses the location of Olivia's body, which was buried in Binky's garden, although omits that she in fact murdered her, so she would remain a pure child of God and not be molested by their father.
