Overview:For ten years Lena Drömer has been traveling to Tuscany alone for four weeks every November - at least that's what her husband, the Protestant pastor Hermann, and her daughter believe. But this time it will be a journey without return. Shortly after her departure Lena is killed in a bus accident near Bremen. Her death gives up Hermann Rätsel. Why did she die in the north, when she wanted to go to the south? When, as every year in November, a postcard from Lena arrives from Italy, Hermann sets off in search of the truth.
