S50E35 : Borowski and the House by the Sea

In a coastal forest near Kiel, Commissioners Klaus Borowski and Mila Sahin run eight-year-old Simon out of nowhere. Confused, the boy reports that his grandfather was dead in the forest, that he had been attacked by a dog and protected by an Indian. Borowski hurriedly searches the forest, but finds nothing. Instead, he notices a sailing ship anchored in the bay. When Commissioners bring Simon back to his parents Johann and Nadja Flemming, it is confirmed that Grandfather Heinrich has disappeared. He suffered from Alzheimer's and often just started disoriented.
