Another wonderful Le Carre novel. This time the main theme is how being a sort of psychologically fluid and ungrounded con-man is an ideal preparation for being a spy. In this sense it is reminiscent of the Tailor of Panama, though I enjoyed the main character in this book much more. Confession: I listened to this as an audio-book. Le Carre is a great reader, and I love his American characters/impersonations to no end. I would listen/read/watch him do portraits of Americans for as long as he was willing to produce them.
