Widower Eberhard Bauer is found murdered, having run up high debt on dubious 0900-'hotlines', just to talk to girls. Teen son Nick moved to friends, his study fund was largely wasted on the sex lines, yet Nick Bauer says dad started paying him back, recently 3,000 Euro, but there's no record. Hotline manager Maike Wagner says Eberhard sort of stalked her employee, Franka Turner alias "Lana", who claims not to have noticed - maybe her husband Ingo Turner did? Then an earlier link between Eberhard Bauer and Franka Turner means a twist.
