Vince Wain is visiting his ex-wife Brenda and their son Martin. While he is at their house he helps himself to their savings and is very surprised when Brenda goes to the police about it. During the following row Martin decides to run away and asks David to help him. They even become blood brothers and promise each other not to let each other down. Mr. Turner is cleaning windows at Ashfordly Hall when he is bitten by his lordship's dog Jack and demands that the dog is put to sleep. Lord Ashfordly even risks being charged in that he cannot prove that the dog is not a danger to the public - no easy task because Jack has quite a history in the biting department. Luckily for him help is not far away and Aunt Peggy offers to train him - the dog that is, not Lord Ashfordly.

On her way home from night class Sandra Proctor is forced off the road by a hit-and-run driver. Alan Seddon's car was stolen outside the dance hall in Ashfordly. Alan is the son of Roy Seddon, the councillor on the police committee, and Sergeant Miller gives the case top priority. The car is found abandoned, and it turns out to be the car that hit Sandra Proctor. Alan is known for his wild driving and neither his girlfriend Hayley nor his best friend Paul can give him an alibi for the entire evening, so he may have caused the accident and reported the car stolen to cover his tracks. David is fed up with being ordered around by Aunt Peggy and accepts a job with the window cleaner Topsy Turner instead. But Peggy is not prepared to give up on him that easy.
