Just read a ridiculous piece (Mail I'm afraid) on her death. First, the speculation that she was pregnant (because of an "unmistakeable pregnancy bump" shown on that yacht when wearing a swimming costume and slouching slightly) - since when has a pregnancy, that could only have been a few weeks along, shown visibly? And her good friend Rosa Monckton holidayed with her a week-10 days or so beforehand and reported, in the most delicate way she could, that she'd been on her period at the time.
But the most ludicrous theory of all, was the "testimony" from a French couple driving ahead of the car in that tunnel, who said they saw, through their rear-view mirror, a motorbike stop at the wreckage, the rider get off, peer through the window and turn to give his accomplice a recognised military signal for "mission accomplished." How on earth could two people in a car (two rear-view mirrors??) see all that as their own car was travelling away from the scene, presumably at a reasonable speed. They were ahead of Diana's car, there would need to be time for it to swerve, hit the pillar, skid to a stop, the bike to stop, the rider alight, pick his way through scattered debris, establish the scene inside and then make his "signal." And the Pont d'Alma tunnel, if I recall correctly, is not straight, which means there would be no direct view from a distance due to a curve in the road.
And why the hell did they not stop their car to assist?
