About the book:
A man's body is found in an empty house. His heart has been cut out and delivered to his family.
He is the first victim, and DI Helen Grace knows he will not be the last. But why would a happily married man be this far from home at night?
The media call it Jack the Ripper in reverse: a serial killer preying on family men who lead hidden double lives.
Helen senses the fury behind the murders. But what she cannot possibly predict is how volatile this killer is - or what awaits at the end of the chase...
