Earl Spencer's 'Swan Song: Diana, My Sister' went on sale on Tuesday. It alleges King Charles sounded "giddily elated... like a lottery winner" after Diana, Princess of Wales's death in 1997. Buckingham Palace said "the pain of fraternal grief can cloud reason". Spencer told People Magazine Prince Harry is "completely fine" with the book.
