Does an article revealing the not-so-well-kept secret that Arthur Miller had a son with Down’s Syndrome, whom he cut entirely out of his life as an infant, taint Miller’s legacy as a playwright? “For many of those who came of age in the middle of the last century a saintly glow hovers around Miller, whose plays have often examined questions of guilt and morality through the prism of family. He was a hero of the left and a champion of the downtrodden.” That image is now in danger of shattering.
