Spyforce

Spyforce was a strong Australian WW2 spy/action series, with exciting scripts and a good cast. What made it stand out was the two lead characters - Jack Thompson as the archetypal Aussie and Peter Sumner as his German-born partner - who were constantly at odds due to Jack's doubts over Peter's true loyalties. I must admit its been a long time since I saw the show, but my recollection is that although Peter's character was sympathetically developed and complex, there was always a wee bit of doubt about whether MAYBE he really was a double agent.
