Based on the novel Started Early, Took My Dog by Kate Atkinson.
A new case comes calling when a woman searching for her birth parents approaches Jackson for help. His search takes him into the dark heart of 1979 police corruption and murder – and a secret that has remained buried for nearly 35 years.
His investigation crosses paths with Tracy Waterhouse (Victoria Wood), a retired police officer turned store detective. When Tracy witnesses a little girl being physically abused by her mother, she takes a surprising course of action which stirs the past for her and former police partner Barry (Gary Lewis), and presents a moral dilemma for Jackson.
A woman is convinced that her daughter’s riding accident was murder and, through his investigation, Jackson must confront some difficult truths about the destructive nature of love. Meanwhile, a new client asks Jackson to find out if her fiancé is cheating on her, and Jackson gets more than he bargained for after a surprising win at the races. His relationship with his own daughter, Marlee (Millie Innes), gets more complicated too.
Episode Two is an original screenplay.
