The Quiller Memorandum (1966) by Michael Andersen

Quiller (George Segal) cannot be fooled, even though they try their hardest. And he doesn’t like to be followed either. Certainly not by his own league. Nobody knows what he is up to, but he has everybody under control. His enemies as well as his colleagues. Quiller keeps his cards well hidden and the trump won’t be played until the right moment has come. And be sure, he will always have the winning hand.
