One of the letters is dated August 6, 1997, which was the last day of a holiday she had with Dodi on a yacht owned by the Fayed family. In it, she said: "Darling Dodi, heaven knows how I can thank you. I adored it all and every minute was full of laughter and happiness. I have never felt such rigid burden being removed as what happened with you. As always, I give you heartfelt thanks for bringing such joy into this particular chick's life." (Sky News)
