Was she murdered? Was it a tragic accident? Was she pregnant? Where did that white car that clipped the Merc go? Do you care?
An official UK police inquiry into the Paris car crash which killed Princess Diana and Dodi Al Fayed has found no evidence the couple were murdered.
Lord Stevens, who led the three-year investigation, said the crash was a "tragic accident".
The inquiry report said chauffeur Henri Paul, who also died, was speeding and over the legal drink-drive limit.
The princess, 36, and Mr Al Fayed, 42, died when their Mercedes crashed in the Pont de l'Alma tunnel in August 1997.
Part of the inquiry's remit has been to investigate the conspiracy theories.
The findings - contained within an 832 page document - form part of the inquest, due to resume next year, into the deaths of the couple.
Lord Stevens told a news conference in London the report addresses the key issues emerging from a "most complex and challenging" investigation.
Lord Stevens said he hoped the report would bring "some closure"
"I have no doubt that speculation as to what happened that night will continue and that there are some matters, as in many other investigations, about which we may never find a definitive answer.
"However, I do not believe that any evidence currently exists that can substantiate the allegation of conspiracy to murder that has been made."
Princess Diana was not engaged or about to get engaged and was not pregnant, he said.
Some 400 people, including Prince Charles, the Duke of Edinburgh and the heads of MI5 and MI6, were interviewed by the inquiry.
Referring to claims by Dodi's father, Mohamed al Fayed, the report said there was no evidence of a connection between the Duke of Edinburgh and MI6.
Mr Stevens said the various legal cases currently being pursued by Mr Al Fayed through the French courts are "unlikely, in my opinion, to have any bearing on my conclusion that there was no conspiracy or cover up".
He said: "I very much hope that all the work we have done and the publication of this report will help to bring some closure to all who continue to mourn the deaths of Diana, Princess of Wales, Dodi Al Fayed and Henri Paul."
The crash took place as the couple were pursued by paparazzi photographers during the drive from the Ritz hotel to Mr Al Fayed's flat.
A French investigation into the crash concluded Mr Paul had lost control of the car because he was driving too fast while under the influence of alcohol and prescription drugs.
