[1] The book is based on an imaginative fictional elaboration of the actual forensic evidence that the Mercedes carrying Diana, Princess of Wales had had a glancing contact with another car, believed to be a white Fiat Uno at some point before it crashed in the Pont de l'Alma tunnel in Paris on 31 August 1997.

In Paris, Veronique has just split up with her boyfriend and is driving home in her "little white car."

While passing through a tunnel in central Paris, a large car approaches from behind at high speed.

Veronique is determined to not let it pass, and it collides with the back of her car and crashes.

The remainder of the book tells of Veronique's life and loves before the crash, and the subsequent efforts to conceal her involvement.
