'Game, Set and Match' (1988) TV serial of Len Deighton Book Trilogy [2 of 13]

'Game, Set and Match' is a 1988 television serial directed by Ken Grieve and Patrick Lau and written by John Howlett. It is based on the books, 'Berlin Game' (1983), 'Mexico Set' (1984), and 'London Match' (1985) by Len Deighton.

It was hugely expensive to make and a massive flop (the sound engineering is an utter disgrace, and Ian Holm cast as Bernard Samson is ludicrous). But it deserves to be saved, I think.

Berlin Game: Part 2:
A leak from within London Central has been discovered in the German arm of the British SIS. The leak causes concern among the higher levels of the SIS in regard to their East German "Brahms Network", especially their most valuable agent, "Brahms Four".
