Santini is determined to find out if Jess Orton has grassed on him, and when he breaks into her home to challenge her, he causes her to fatally fall down the stairs. Fox is ordered off the case by DCI Pallister and warned that if her actions directly resulted in her death, then she could be facing criminal charges. Vicky plugs DS Timpney for information, suspicious that Santini may not be telling the whole truth. Desperate to conceal his involvement with the Ortons, Santini and Fox find themselves captured by Sherman and Ferguson, and facing possible execution. Fox believes she has a confession for Orton's murder and is attacked by Santini, but after their rescue, it's Santini's girlfriend Hagen who nails him for the murder.
