And yet there is the Andrew Morton book, Diana: Her True Story. Extremely partisan, but not bullshit.
The Sun had an exclusive splash just before Diana married Charles in July 1981 of her meeting him for a sexy assignation on the Royal train which was parked in sidings near his home Highgrove, in Tetbury, Gloucestershire.
There was a grainy long shot of a woman with fluffy blonde hair being hustled on to the train. The Royals didn't dignify the story with a comment. They never do. Diana always let it be known through "friends" that it wasn't her.
Camilla Parker-Bowles is blonde with a fluffy hairstyle and lived near Highgrove at the time. She still does because she retained her marital home on divorce and it is often described as her bolthole, which is completely normal, isn't it? We all maintain large second homes away from our current spouse, don't we?
For a long time I've wondered whether The Sun knew at the time it probably wasn't Diana, or just fell in later. I think they did but it wasn't convenient to say.
