What an amazing thriller! Absolutely loved it; every roller coaster moment of it. This book was full of surprises, and there was no boring moment. I highly recommend it.

It changed her life. Isla Bell is a professor of criminal psychology, a profession that she was steered into after finding three murder victims leaning against Hadrian’s Wall when she was just a girl. She studies the minds of killers and psychopaths, trying to understand what drives some people to commit such horrendous acts. The Hadrian’s Wall killer, Heath McGowan, was caught by Isla’s own detective father, and has only now agreed to speak to her about the murders. Her husband, the only one of Heath’s victims to survive doesn’t want her going anywhere near the killer, but she can’t turn down this chance to further her research. When another body is found, the similarities to the earlier murders are impossible to miss. Did Heath has a partner, is a copycat at work, or was the wrong man imprisoned? Wow! This novel is so twisted and so brilliantly plotted that you will be blown away. One of the best mysteries I’ve read in a while
