1975

It's the worst thing Detective Bill Roach has ever seen. The young woman's body is found beside a busy road. She's been disembowelled - while she was still alive. Placed on her chest is a cassette player. Inside is a sixty-minute tape, playing just one song over and over again: Mack the Knife.

With his copper's instincts, Bill knows this isn't the last they'll hear of the killer they call Jack the Knife. He's right. The hunt for Jack won't end for almost fifty years.

Present day

Eighty-year-old former police detective Bill Roach sits at the bedside of elderly Gillian Lake, comforting her as she slips away. A popular resident at the Crown Woods Retirement Home, Bill sees it as an act of kindness to ensure his fellow residents don't die alone.

But the post-mortem throws up shocking results. Gillian didn't die of old age. She was murdered.

Bill never caught Jack the Knife. But now he has a chance to make good the past - and catch Gillian's killer.

But Bill's hunt for the truth will expose dangerous secrets. Past secrets that will burst into the present . . . with horrifying results.
