Months after the events of DR. CUBA, Inspector Heiner Thumann, newly appointed to the nascent Interpol, must return to his home country of Germany and investigate a rash of murders that has spread across post-war Stuttgart. Thumann must confront the memories of his own experiences with the Nazis, even as the evidence begins to suggest that he and his Co-Inspector, Ximena Torres, are facing more than one potential serial killer. Rumors run rampant across Germany that the killings are not that of a man, but a giant, lumbering clay beast resembling the Golem of ancient Talmudic myth.
