A girl who has seen more darkness than most. A Scottish lawyer waiting to be killed. A fingerprint discovered at a murder scene, from a man who couldn't possibly have been there. As DI Alex Morrow investigates the death of a young businessman, she uncovers a vicious network of power and corruption that reaches back to Glasgow on the night Princess Diana died. And to a fourteen-year-old girl sat in a car with a dead body, the murder weapon still in her hand.
