Fishermen find the floating corpse of Judith Boll. She was fatally stabbed, perhaps mugged, on her birthday. She expected a managerial promotion in Rufus Eckmann's shipping company and recently got engaged with Simon Schaaf, who refused to join the collegiate celebration. Colleagues claim they waited in vain for her. Judith Boll sneaked out of office abnormally early and met a man. A key next to the victim fits her home nor office. The team finds locked-away dirty secrets, also involving the boss's wife Lisa.
