Princess Diana, her eyes wistful and her face beautiful, look straight into your eyes. And in sad, husky tones related the story of how she became an emotional wreck when she discovered her Prince Charming loved somebody else. Also laid bare were her intense boneliness amid all the glamour of the royalty, her desperate attempts to harm herself physically and, in this sad state of affairs, her seeking consolation in an adulterous affair with a cavalry officer who was also her horse riding instructor. Only to be let down again with the man going public about the relationship. On November 20, when Diana's interview was telecast on BBC 1's Panorama programme, nothing else mattered in Britain.
