Harper Lee’s novel To Kill a Mockingbird became iconic almost immediately after appearing in 1960: best-seller status; the Pulitzer Prize the next year; a classic movie soon after, with Gregory Peck in an Academy Award–winning role. It has since gone on to sell more than 40 million copies in umpteen editions, and has become obligatory on high school reading lists (which also means it is widely banned). The copy I picked up recently references the original cover art but the flap copy no longer describes it as a novel—instead, it is “one of the best-loved stories of all time,” for once not an exaggeration. The very idea of its being a “story” preserves Mockingbird’s Southernness—a tale told, and well—while transforming it safely into a kind of universally known folklore.
