The Hong Kong local police are looking into the apparently motive-less murder of a businessman. Fitz is in town lecturing at a university and as the police are getting nowhere and requiring a quick result they call him in to assist on the case. While working in a foreign location, in a different culture, with detectives not used to serial killings, Fitz is confronted with yet another murder. Time is running out. Fitz is convinced that a western ex-patriot is behind the brutal slayings, but can he make the connection in time?
