A sadistic murderer preys on his victim‘s biggest fears.How&why he chooses to kill women by targeting their children is what forensic psychologist Joe O‘Loughlin tries to find out with the help of retired detective Ruiz&the police.The story unfolds alternating between O‘Loughlin‘s&the killer‘s view.Some characters are a bit one-dimensional,but Joe,who has Parkinson‘s,is very likeable,the writing style is good,witty,the story gripping.Loved it
