Only halfway through the 4-part series so far but Cambridge Spies has definitely lived up to my expectations. Much impressed by the excellent Toby Stephens, having seen how versatile he can be from: Tenant of Wildfell Hall, Sunset Heights, Great Gatsby and of course Die Another Day! I have to say what a superb actor Tom Holland is too. Putting aside historical inaccuracies (this has never claimed to be a documentary anyway) in favour of sheer entertainment value, this is proving to be a fast-moving, truly gripping drama. I'm hooked!
