Meet 'The Protectors': Ian Souter, Robert Shoesmith and their Girl Friday, Heather Keys. Their motto: 'We Sell Security'. Their object: to prevent crime. Operating from a smart Marylebone office, they form a high-powered private investigation team dedicated to fighting crooks and forestalling crimes of all kinds in the twilight borderland between the underworld and the policeman's beat. This classic ABC adventure series stars former RSC player Andrew Faulds as the fiercely moral Souter, a Black Watch officer turned private detective; Michael Atkinson is fellow troubleshooter Shoesmith, an ex-policeman with an unnervingly acute understanding of the mind and methods of the criminal; Ann Morrish is secretary and confidante Heather, a former auctioneers' assistant with a sharp eye for art fakes and forgeries.
