Query: Don't buy this book; you've heard it all before.

I was extremely disappointed with "Charles at Fifty" for three reasons. First, the title is grossly misleading. It implies that most or all of the book will examine the Prince of Wales as he is today (i.e., how he's handling Diana's death; his relationship with his sons and Camilla, his parents, etc.) Instead, almost all of it is a biography of Charles, going back all 50 years. Relatively little focuses on Charles after the divorce. Second, there's very little here that we've not already seen or heard somewhere else. (Readers are forced to sit through yet another rehashing of the Waleses' maital woes.) Third, the book is terribly one-sided. Diana is portrayed as the innocent victim of a cold, heartless, selfish man who used her. Little effort is made at telling his side of the story. Far superior to Holden's book is Penny Junor's "Charles: Villian or Victim;" however, be warned that Junor is VERY pro-Charles.
