Diana: Her True Story was originally published in 1992 under the guise of a quasi-authorised biography with mostly unnamed courtiers and royalty as the accredited sources. It instantly became a sizzling, international bestseller that lanced the boil of Windsor family dysfunction, triggering a chain of events that led to Charles and Diana's divorce. After her tragic death in 1997, Andrew Morton revealed that Diana herself had not only been the main source for the book, but had also edited his original drafts for accuracy.
