Burden of Proof

Blaketon becomes the prime suspect in a murder enquiry when he is asked to spy on an adulterous coal merchant by his wife. After the man is found dead, his wife claims she and Blaketon are lovers, leaving Rob to lead his own investigation to clear the private detective's name. Meanwhile, Bellamy falls in love with a young widow with three children, living on the Ashfordly council estate, when he attends to a burglary at her house, and Peggy fails to back a winner when she buys a greyhound that refuses to run.
