The New York Times – Alan Furst: In A Most Wanted Man, the sheer desperation of those whose job it is to prevent another 9/11, another Madrid commuter train, another London Tube attack, is written as a slow-burning fire in every line, and that's what makes it nearly impossible to mark the page and go to sleep. Something said earlier in this review might better be amended. The concept of "best book" is difficult for the writer and reader; there are too many variables. Truer to say that this is le Carre's strongest, most powerful novel, which has a great deal to do with its near perfect narrative pace and the pleasure of its prose, but even more to do with the emotions of its audience, what the reader brings to the book. There the television has once again done its work, has created a reality, and John le Carre has written an extraordinary novel of that reality.
