Of all the things Princess Diana lost in the demise of her marriage to Prince Charles, the most painful, by far, may have been her emotional stability. After the separation, Diana felt an encroaching sense she was being spied upon and had her rooms at Kensington Palace swept for bugs. And she may well have been right, according to an electronics expert who detected an electronic eavesdropping signal in Diana’s bedroom in 1994. The year before, she’d dispensed with police protection because she feared detectives had been hired to spy on her. By 1996, Diana had come to feel her life was in danger. In fact, she was certain there was a murderous plot afoot. And she was also certain of how it would play out.
