“Literary biography—an enterprise Updike regarded with some skepticism—is largely a hunt for such deeply buried evidence. As an aid to future biographers and anyone else interested in pursuing the mystery of Updike’s prodigious talent, I’d suggest paying attention to his lifelong love affair with cartooning, a passion that burned hottest when he was young but remained warm until his dying days, when he ceased to draw but still repeatedly referred to the comics he had loved in childhood.”
