John Updike in The New Yorker:
Hugger-mugger takes a lot of explaining, a lot of diagramming. An additional trouble with it, which keeps the suspense thriller, however skillful and polished, a subgenre, is that the novelist, manipulating his human counters on the board, must keep them somewhat blank, with selective disclosure of their inner lives, lest the killer or mole or whatever be prematurely unmasked. Even the most intimate human matters are turned into diagrams. Salvo’s love, Hannah (not to be confused with his wife, Penelope), is thus addressed by an Americanized friend, Baptiste:
“Let’s do facts. Here are the facts. Your friend here fucks you, right? Your friend’s friend knows he fucks you, so he comes to your friend. And he tells your friend a story, which your friend repeats to you because he’s fucking you. You are rightly incensed by this story, so you bring your friend who is fucking you to me, so that he can tell it all over again, which is what your friend’s friend reckoned would happen all along. We call that disinformation.”
Between information and disinformation, characters don’t have much breathing room.
