This is another 1960s ITC series gem. It follows the dangers faced by Mc Gill, a disgraced American secret service man, who now is based in London, and getting PI work for money as he can. While this is certainly as good as others of its ilk, such as The Saint and The Champions, etc, I have found this one to have its own unique flavour. I think that this is because, while we are not subjected to the "nitty gritty" of extreme violence that such a series would have in our current era, Mc Gill puts up a very realistic fight when required. Another difference with this series for me is that the chief actor playing Mc Gill, Richard Bradford, doesn't put the same effort of flirting with the camera that was so prominent at the time of this production. He appears to put his whole self into acting the character he is portraying, and the result is charismatic acting that is unique. If only more episodes were made. The DVD set includes a recent interview with the actor which is interesting in that he explains how he felt about the production of the series, and he also offers an interesting explanation of his approach to his acting during this series. Amazon, please offer more DVDs of this actors work.
