This classic cover from TV Times dates back to 1967 and on the cover is the late actor Gerald Flood who at the time was starring in the ITV intelligence series, "The Rat Catchers....."
The Rat Catchers was a 1960s British television series about a top secret British Intelligence Unit who receive orders from the Prime Minister and without questions battles enemy spies, saboteurs, and other criminals in order to protect the security of Great Britain and the Western Alliance. The show centred around three major characters: Peregrine Pascale Smith (portrayed by Gerald Flood), the Oxford University-educated managing director with 12 years experience under his belt, Brigadier H. St. J. Davidson (portrayed by Philip Stone), the emotionless analytical brains behind the group, and newly-recruited Richard William Hurst (portrayed by Glyn Owen), formerly a superintendent at Scotland Yard who though he was said to have gone by the book in the police force, seems to have some problems with authority now. Part of the problem is that the Brigadier refuses to tell him more than the minimum that he needs to know about the organisation. Officially he works for Smith's company: Transworld Electronics and in episode 3, he is not sure whether Smith or the Brigadier is his boss.
