Tatort S2006E08 - Blum - 09 - Der schwedische Freund

A man lies dead in a park in Konstanz. In his wallet is a passport that identifies him as a Swede. Klara Blum requests administrative assistance from Stockholm to find out more about the dead man. When support arrives in the person of the attractive Stockholm detective Bo Johansson, it turns out that the dead man is a prominent Swedish industrialist. Bo Johansson and the murdered Sunderström have a common history: many years ago, Sunderström was suspected of having killed Bo Johansson's daughter's ex-boyfriendbut was acquitted for lack of evidence. Klara finds the Swedish colleague very likeable and involves him in the investigation. To the displeasure of Kai Perlmann, who feels marginalized and who is rather suspicious of the Swedes.
But Klara's trust in Bo begins to falter when she finds out that Bo's daughter lives near Konstanz and was seen in the park shortly before the crime. Torn between attraction and distrust, Klara Blum sets out to uncover Bo Johansson's secret.
