For women with an eye for macho men, Darren Dee O'Neall seemed to be the kind of guy that romantic dreams are made of: strong, handsome and with the demeanour of a rugged outdoorsman. But in reality, O'Neall was a living nightmare: a vicious monster with a history of sexually violent crimes so savage that he was on the FBI's Most Wanted list. Top true crime author Gary C. King gives us the whole story, including: a twisted killer, whose ability to change his appearance confounded authorities over and over again; a mother's agonizing search for her missing daughter; and a police investigation that finally led to the arrest of one of the most dangerous men in American history.
