DI Henley believes the serial killer she helped put in prison might help her with the copycat killings. His way of helping her was not what she intended. The background information was a bit forced, but the action in this thriller was enough to keep it moving. It’s a bit gruesome, so if you like crime shows that are pretty graphic, this may be to your taste. I found it a bit cliched that the criminal was trying to get the detective’s attention, but then, I wonder how often that happens IRL. I was fortunate to receive a digital copy from the publisher Hanover Square Press through NetGalley.
