The police pursue a number of leads, but Mowbray strongly suspects Robert Jackson, a delivery driver with a previous record of violence against women. Mowbray's boss disagrees, however, and the detective must decide whether to charge Jackson.

Mowbray takes himself off the case, goes on leave, and tries to patch things up with Sally and the kids. While he's gone, the police make an arrest. DCS Henderson believes he has his man but needs a confession to be sure.
