On captain Reuter's day off, Elena Trakies is found at the beach skull-smashed with an iron rod thrown in the sea. The Latvian was one of the attractive Baltic potential brides offered by dating service "Ostseesonne". Managing owner Hannelore Kramer says she can't imagine why Elena returned after her match with school principal Heinrich Braake fell through, as he found her a gold-digger. The team finds there were many dissatisfied male clients, but about the time of the murder the while card database is gone and reported a robbery. Reuter goes undercover and charms Hannelore herself.
