Inspector George Gently S04E02 - Goodbye China

The detective looks into the suspicious death of an old friend and informant nicknamed "China", when he is told conflicting reasons for the man's demise by the coroner and the nurse who tended him in his final few hours. The investigation leads Gently to the local police station, where it becomes clear the officers are hiding something – and to complicate matters, the disappearance of a teenage boy is also linked to the case.
