A crime series.
This week: Paul Dawkins as Joyce Porter's Det. Chief Insp. Dover investigates the case of Dover and the Poison Pen Letters
Dramatised by James MacTaggart.
Also starring Tenniel Evans

Detective Chief Inspector Dover is middle-aged, fat, dyspeptic, lazy, and frankly unintelligent.
An outbreak of poison-pen letters in a remote village provides the Assistant Commissioner at Scotland Yard with a longed-for opportunity of getting rid of him for a time. Dover's efforts are, as usual, desultory, and their immediate effect is to produce one attempted and one successful suicide. Only Det.-Sgt. MacGregor, Dover's assistant, suspects that the successful suicide is, in fact, a case of murder.
