Shame — Alan Russell

Gray Parker's execution was front-page news and his case even inspired a bestselling book. Everyone wanted to hear about the man who strangled all those women. Everyone except his young son. As soon as he was old enough, Caleb moved away, started a new life and denied any connection to his infamous father.
But now new bodies have started to turn up, marked in the same way that his father once marked them, and all the evidence points to Caleb. The only person who believes he's innocent is the one woman who survived one of Gray Parker's attacks, the woman who turned his crimes into a bestseller.Together, these unlikely allies must desperately try to prove Caleb is innocent … before either the law or the killer can catch them.
