Marnie Logan has more than her share of problems: her husband has disappeared; a violent debt collector is demanding money from her; and she's convinced someone is following her. When the debt collector is found dead, only her London-based psychologist, Joe O'Loughlin, thinks she might be innocent. Then O'Loughlin uncovers evidence that a cold-blooded killer is eliminating people in Marnie's life. Could he be the next in line? Another edge-of-your-seat thriller from the author of Say You're Sorry (2012).
