It seems as though Oprah is not going to respond to an unauthorized biography from Kitty Kelley, yet she built her career on the examination of other people’s lives (“Oprah’s ‘Hidden’ Life,” April 13).

It’s quite strange that Oprah began her last season of shows revealing the face of the lady who was attacked by a chimpanzee, but when it comes to really knowing Oprah herself, we have to settle for an unauthorized biography.
