I love John Le Carre's novels, or should I say I love the BBC radio and tv versions of his work. However, this production is very disappointing for being so muddled it's impossible to follow the plot. At first I thought it was my fault for not paying enough attention, but by episode 3 I realised that it was just poorly adapted. I remember the terrorist events of the 70's and 80's, but even so I just couldn't get a hold of the storyline here. Finally, I've given up trying, as it was not entertaining me at all!
