“Mr. le Carré is maybe the most eccentric constructor of fiction in English literature since Joseph Conrad. His stories are full of digressions and long flashbacks; he circles around his plots for the longest time, as if he were doing reconnaissance on them before deciding to go in for the kill. And the verbal textures of the books can be challenging too, because his spies tend to speak in their own special jargon, which seems like normal speech, but isn’t quite.”
