This book took a very long time to develop, but that's typical of John le Carre, isn't it? When the psychological state of the protagonist is the most important driving factor, it takes time to build to that point of action. But even when you reach that point in The Mission Song
, it isn't enough to rank this among le Carre's greats. It took me a long time to care enough to finish the book, and even when I did, the victims who were going to be affected by the "operation" were faceless and distant, making it hard to care. Perhaps this is le Carre's point.
