When evil knows no bounds... Private investigator Ravn has finally found a fragile peace on his houseboat in Copenhagen. But when a new client appears with a chilling request, Ravn is pulled back into the darkness he thought he'd left behind. Seventeen years ago, two boys committed an unthinkable crime and vanished into new identities under witness protection. Now, a series of brutal attacks on women is shaking the city, and Ravn's client fears his old friend is the perpetrator. As Ravn digs deeper, he's drawn into a dangerous game of cat and mouse, where nothing is as it seems and everyone has something to hide. With time running out and the body count rising, Ravn must confront the shadows of the past to stop a killer before he strikes again. But can he trust his client, or himself? The fourth book in Michael Katz Krefeld's gripping Ravn series. Perfect for fans of Dept. Q by Jussi Adler-Olsen and Søren Sveistrup's The Chestnut Man.
