Will Hurley was an attractive, charming, and impressive student at Dublin's elite St. John's College - and Ireland's most prolific serial killer. Having stalked his five young victims, he drowned them in the muddy waters of the Grand Canal. Sentenced to life imprisonment when he was just 19, Will is locked away in the city's Central Psychiatric Hospital.
Freshman Alison Smith moved to the Big Smoke to enroll in St. John's and soon fell hard for Will Hurley. Her world bloomed...and then imploded when Liz, her best friend, became the latest victim of the Canal Killer - and the Canal Killer turned out to be the boy who'd been sleeping in her bed. Alison fled to the Netherlands and, in 10 years, has never once looked back.
When a young woman's body is found in the Grand Canal, Garda detectives visit Will to see if he can assist them in solving what looks like a copycat killing. Instead, Will tells them he has something new to confess - but there's only one person he's prepared to confess it to.The last thing Alison wants is to be pulled back into the past she's worked so hard to leave behind. Reluctantly, she returns to the city she hasn't set foot in for more than a decade to face the man who murdered the woman she was supposed to become.
Only to discover that, until now, Will has left out the worst part of all.
