Missing, Presumed Dead - S3.E4

There's been a shooting, but none of the neighbours seem to have witnessed anything. While chasing a possible suspect, Sgt. Bob Cryer hits a pedestrian. During door to door inquiries P.C. Yorkie Smith discovers a man with exotic animals including snakes, owls and a crocodile in his bathtub. D.S. Roach is attacked by some thugs, and the next day tries to beat them with an iron bar until P.C. Carver stops him. His attackers are later kneecapped as a message to D.I. Galloway as to who really is the law on the manor.
