I really believe this was THE most boring book I have ever had the persistence to wade through, and I have little doubt it is the most suspense-less spy novel ever written. It is a horrible, horrible waste of time, IMHO.
The book has no real story line to speak of, its plot can be summed up as: a British/Czech double agent goes into hiding after the death of his father, his British bosses feverishly searching for him, and in the end he is cornered and shoots himself. In the meantime, we read page after page after page about the agent's childhood, his con man father, his more or less wasted attempts at education, his love affairs, and his youth friendship with a German in Bern, who he betrays, and who later uses his guilt to recruit him as a double agent for the Czech intelligence service. Not only that, we even read about the childhood of the father, and all of his life's story. An item that at first glance seems to be playing an important role in the story is a metal filing cabinet that the father keeps lugging around for no apparent reason, containing evidence of his crimes. It is ominously mentioned every few pages, and people seem to be going to great lengths to get to it, but in the end, nothing comes off it. Ah well...
The writing style if confusing, to put it mildly. Le Carre switches between cases, places and times, with no discernible boundaries. "Linguistic artistry" is what they call it - must be modern art then. You would probably have to read it multiple times to get through this mess, but there is really no point, the book is so tedious you just don't feel any need to understand the fine points.
I am truly utterly mystified what people see in this book. It supposedly was a #1 NY Times bestseller, there are glowing reviews right here at Amazon - hmm. "Epic in scope and length" - that I can attest to, it is epic all right. "Masterful" - that is highly debatable.
Well, I guess it must be me then, I probably just don't get it. Just be warned: this is NOT a thriller, not by any stretch, and in the broadest and most benevolent sense. There is just no suspense. But if you are looking for an epic, and have read the Encyclopedia Britannica already, then this book may be for you.
