As evening falls against the majestic backdrop of the Bavarian Alps, Charles Hirter, an American tourist, is savagely murdered. In the peace, quiet and pastoral splendor of this magnificent setting, Charles Hirter draws his last breath. Was Charles simply in the wrong place at the wrong time? Kommissar Franz Waldbaer, the German detective in charge of the case, faces an investigation that yields neither clues nor suspects nor motives. A gruff, go-it alone detective, Waldbaer is dismayed by the arrival of Robert Hirter, the victim's brother, who insists on joining the investigation. But there is more to Robert than meets the eye. As Robert and the Kommissar uncover a nefarious nexus of evil past and evil present, they find themselves probing dark, long-forgotten episodes from the Third Reich in order to identify the present threat. Thrust into a violent world of fanatic passions, malevolent intentions and excruciating urgency, Robert Hirter and Kommissar Waldbaer must race against the clock to stop a sophisticated, covert, and deadly plot.
