In this second Black Forest Investigation, Chief Inspector Louise Boni returns from rehab at a Buddhist monastery after the events of the award-winning Zen and the Art of Murder.With a shaky grasp on her newfound sobriety, Boni resumes work with the criminal investigation department. Her first assignment, the probe of a fireman's death while battling the explosion of a secret underground weapons cache, reveals connections to both neo-Nazis and illegal arms dealers from the former Yugoslavia. But the sudden incursion of secret service agents into the scene indicates more far-reaching possibilities. Boni must come to grips with the dark forces behind the hidden munitions, the divided loyalties of a new partner, and the ghosts of her own past while trying to resolve the most challenging case of her career.
