Amy Petty is dead, but Amy Petty is alive . . .
When an inter-city service travelling from Kent to London joins Paddington, Hatfield and Selby in a deadly list of notoriety, it isn't only fate who decides who is killed; one passenger uses the opportunity for argument to spill over into murder; whilst another - blonde, beautiful Amy Petty - sees the train crash as an opportunity to leave her life behind.
But why would Amy want the world to presume her dead? Is it because of her husband - the rich, charismatic and evil-tempered Douglas Petty - currently embroiled in a libel action against a national newspaper? Or maybe it isn't the present that Amy is running from. Maybe it's the past from which she cannot escape . . .
