Michael Cole is the only person who knew all three victims of the fatal Pont de l'Alma road tunnel crash that occurred in Paris, in the early hours of 31 August, 1997: Diana, Princess of Wales, Dodi Al Fayed and Henri Paul, their driver. Michael discovered that the Princess had not survived her terrible injuries nearly two hours before news of her death was announced by the British ambassador. During that surreal interval, it was reported that Diana was not badly injured and had walked to the ambulance. At first, Michael thought the crash was a tragic accident that had robbed two young people of their lives and happiness. Michael accompanied his boss, Mohamed Al Fayed, and his wife, Heini, to the Princess's funeral in Westminster Abbey. But even before that things started to happen which to him, a seasoned journalist and award-winning TV correspondent, seemed strange. He sensed a cover-up, with the authorities on both sides of the Channel anxious to write off the deaths of the world's most celebrated woman and her lover as accidental. But an English jury brought in a verdict of 'Unlawful Killing'. This is the inside story of what really happened.
