I look at the books on my library shelves. They certainly seem dormant. But what if the characters are quietly rearranging themselves? What if Emma Woodhouse doesn’t learn from her mistakes? What if Tom Jones descends into a sodden life of poaching and outlawry? What if Eve resists Satan, remembering God’s injunction and Adam’s loving advice? I imagine all the characters bustling to get back into their places as they feel me taking the book down from the shelf. “Hurry,” they say, “he’ll expect to find us exactly where he left us, never mind how much his life has changed in the meantime.
