'Game, Set and Match' (1988) TV serial of Len Deighton Book Trilogy [3 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 3:
Samson has been sent back to Berlin. He meets with station chief Frank Harrington, then tracks down his childhood friend and former agent Werner Volkmann's wife Zena, who has become Harrington's mistress. Werner is suspected of being the leak, while Samson has suspicions it is Giles Trent of the Foreign Office. He also suspects his wife, Fiona—who is security chief at London Central—is having an affair with his superior Bret Rensselaer.
