 Convinced that Kelvin and Ben are the murderers, Sam Ryan pursues her own investigation. She is also concerned that one of the boys may do himself harm after a third boy, who was only peripherally involved, hangs himself. The police are concerned that her involvement may actually taint some of the evidence they have and an angry DCI Peter Ross informs her that he has filed a formal complaint with the Coroner and the Chief Constable over her conduct. This obviously affects their professional and personal relationship.
