There is a point in every human being when they are lonely. Lisa Brenner knew that moment. When her body is found one gray morning in front of a high-rise building, having fallen from the 12th floor balcony, she leaves behind a number of men who adored and loved her. Lisa was so close and devoted to all of them that in the end nobody knew if he was really her favorite. A tricky case that also deeply shakes the trust between Leitmayr and Batic.
