As soon as the world heard the news of the death of Diana, Princess of Wales in a crash in Paris on 31 August 1997, many questions began to be asked by people who believed it was a conspiracy and not an accident: was she engaged to Dodi Fayed? was she pregnant with Dodi's child? why did the ambulance take so long to get to the hospital? what were the roles of the 'blinding white flash' and the Fiat Uno? were the blood samples taken from the driver switched before testing? Martyn Gregory has interviewed close friends of Diana, the bodyguards who were with her and now for this revised and updated edition the head of the French investigation to delve into the real truth behind the crash. He answers all of these questions and more in an authoritative, exhaustively researched and utterly compelling book that reveals what really happened in Diana's last hours.
