Paperbacks: The Diana Chronicles, by Tina Brown

Sarah Bradford's Diana looked unbeatable, but Brown has at least equalled it with her mix of in-depth research (in the US style, we're given the interview tally: "over 250"), a hell-for-leather narrative and pin-sharp character studies.

The young Prince Charles was a "toxic bachelor, impaled on a life of public duty and private indulgence". We learn the breezy pillow talk of the love of his life: "Pretend I am a rocking horse." Brown's account of the third corner of this triangle may be an embarrassing pleasure in its pink cover, but it is a perceptive assessment of the great trag-edy of our tabloid age.
