The body of a young Mexican woman is found in the Main Valley, south of Würzburg. Inspector Peter Haller and his colleague Birgit Sacher are involved in solving the crime. Haller is not yet forty and was born in Würzburg. He has a quiet love for his city, for its clarity and familiarity. He will never fully understand how people can become criminals in such a beautiful environment. This is the secret drive behind his investigations, in which he is not just concerned with solving the case, but with looking into the soul of the perpetrator.
