Jokes are efficient things and they must be as carefully constructed as mouse traps. And so for me to write a page of a novel is a very slow business, because the whole thing has to be rigged in order to snap at the end. My books are essentially mosaics, thousands and thousands of tiny little chips all glued together, and each chip is this thing I learned to do—this thing I learned to make as a child—which is a little joke.
