A puzzle writer, a classic writer who, at the peak of his career, announced his departure from literature and settled in a remote province far from human temptations. His only work, “Catcher in the Rye,” became a turning point in the history of world literature. The novel’s title—and its main character, Holden Caulfield—is viewed by many generations of young rebels as a code name: starting with the beatniks and hippies and ending with today’s radical youth movements.
