Chain Of Evidence

Eddie Chapman's wife is found murdered on a cliff-top path at the beach. Police suspect Eddie, the smooth talking owner of a tennis school, as does his sister-in-law Sally Partridge when Eddie asks her to sign a money order. Detectives can't prove anything until a gold necklace brings to light the real murderer. Inspector Connolly takes long service leave and Inspector Fox takes his place as head of the Homicide squad.
