" I think this George Smiley novel is a bit disappointing since he's simply invited by Ned to share his knowledge/ideas, that is, he showed up once in a while in a class of young people hoping to be a great secret agent like him. Of course there're some exciting episodes worth reading but, I think, reading his Karla Trilogy is all right and you can say, "That's it!" In other words, you won't feel guilty or inadequate if you skip this one. "
