Apart from my quest for Keys...I do like the other 'keys'..The GOLD KEYS.
As a child growing up in the UK in the 1960s, Television was limited unbelievably to just 2 channels. BBC1 & ITV. Along came BBC2 in 1968.
TV over here seemed to have a strict diet of Coronation Street, Old B & W American Gangster Movies with Cagney, Bogey & Robinson et al, John Wayne War films & John Wayne Westerns, Elliot Ness & The Untouchables, and the early USA TV Shows such as Burke's Law, Wagon Train, Addams Family etc etc.
Of course we had our own great stuff as well such as The Avengers, but the American series produced by Desilu, Quinn Martin and those ilk were very memorable.
THE INVADERS had a big effect on me. I found it morose, bleak, thought provoking & scary.
Classic!!
I've just acquired the full set of 4 books of the series...here they are.
