Louise's date with doctor Patrick Carter is interrupted when she has to attend at a train wreck,caused when an elderly woman driver died at the wheel and crashed her car on the line. Jackson had tried to save her and is in turn rescued by Reggie,a young nanny who knew the dead woman and wants him to locate her employer Joanna Hunter,a doctor,who disappeared with her baby son. She is not convinced by Joanna's husband Neil's story that they are staying with an aunt. Using the identity of Andrew Jones,a man whose wallet Reggie picked up from the railway lines in mistake for Jackson's they hire a car and discover that Neil was lying about Joanna's alleged visit to her aunt. Then Jackson is arrested, as Andrew Jones is a wanted man.

Louise vouches for Jackson,who is released,the real Andrew Jones killing himself,though a sinister link is established between him and an incident from Joanna's girlhood. Through Reggie's brother Billy, Jackson learns that Neil knows more about his family's disappearance than he claims and together Reggie and Jackson track Joanna and her baby down. Jackson's working day is not over, thanks to an obsessive husband in a divorce case.

After Jackson's daughter Marlee returns to live with him, he is approached by Rachel Stewart, who is perturbed by her boyfriend Andy Marshall's frequent disappearances. Jackson follows Andy to a remote farm where he meets Miriam Baker. Miriam believes that the death of her estranged daughter, Isobel Marshall, a noted equestrian, was no accident and blames her then son-in-law -- Andy Marshall. Posing as a friend of Isobel, Jackson calls on Andy and is told by Rachel that he was having an affair with her whilst still married; and a colleague of Isobel reveals that Isobel was planning to take their son Freddie and leave Andy. Jackson discovers that Isobel was less than the golden girl suggested by her public image before working out how she died. His luck seems to be in when he wins a small fortune on a race-horse called Nobody's Darling but sadly the death of the bookmaker leads to the exposure of a scam and the winnings are frozen.
