'Game, Set and Match' (1988) TV serial of Len Deighton Book Trilogy [4 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 4:
Giles Trent has attempted suicide after being confronted as a Russian spy. After agreeing to become a double agent, Trent is murdered by a member of the Brahms Network who believes Trent to be the leak. Samson does not believe Trent was responsible for the leak and was planted by the Russians to divert attention from the real mole. Samson is sent back over the Berlin Wall to contact Brahms Four who wishes to be extracted from East Germany.
