In the middle of a novel, a kind of magical thinking takes over. To clarify, the middle of the novel may not happen in the actual geographical centre of the novel. By middle of the novel I mean whatever page you are on when you stop being part of your household and your family and your partner and children and food shopping and dog feeding and reading the post—I mean when there is nothing in the world except your book, and even as your wife tells you she’s sleeping with your brother her face is a gigantic semi-colon, her arms are parentheses and you are wondering whether rummage is a better verb than rifle. The middle of a novel is a state of mind. Strange things happen in it. Time collapses.
