Ep 4. The Man In The Middle

Judge Fulton discovers there's a traitor in the heart of the British intelligence services and determines that the best people to root out the mole would therefore be outsiders. Enter Danny and Brett who are plunged into the dangerous, double-dealing world of sinister spies and exotic temptresses... Movie legend Terry-Thomas plays Archie Sinclair-Beauchamp bringing a touch of humour to this dramatic episode.
