Benjamin Wendt (17) drifts drowned in the port of Glückstadt, abandoned by two mates after a night out and an argument. They sailed aboard a yacht for wayward youths like them. Marten Behrmann remains missing, Tine Harms returns in the morning. Benjamin's step-father Henning Sandberg, a Swedish consulate official, got off by diplomatic immunity two years earlier when his official car fatally hit Steffen Regner, then 16, without stopping. Oskar wrecked his promotion chances by pressing the case in vain. Steffen's father was in Glückstadt the fatal night. The detectives must tie it all together.
