IN 1965, when it appeared in New Yorker, "Hapworth 16, 1924" left most of the fans disappointed, a feeling shared by the general Salinger fan even today. The story, except for a brief introduction from Buddy Glass, is a letter from Seymour, then aged seven, addressed to his parents, Les and Bessie, and to Boo Boo, Walter and Waker. Buddy is with Seymour— and Zooey and Franny are not yet born.
