'Game, Set and Match' (1988) TV serial of Len Deighton Book Trilogy [9 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.

Mexico Set: Part 4:
Still tracking Stinnes, Bernard himself comes under suspicion that he is a double agent.
