Her first love confessed to five murders.

The truth was so much worse.

Dublin’s notorious Canal Killer is ten years into his life sentence when the body of a young woman is fished out of the Grand Canal. Though detectives suspect a copycat is emulating the crimes Will Hurley confessed to as a teen, they turn to him for help. Will says he has the information the police need, but will only give it to one person – the girl he was dating when he committed his horrific crimes.

Alison Smith has spent a decade building a new life. Having moved abroad, she’s confident that her shattered life in Ireland is finally behind her. But when she gets a request from Dublin imploring her to help prevent another senseless murder, she is pulled back to face the past, and the man, she’s worked so hard to forget.
