The Beijing Ripper is at large, using the gruesome methods of his Victorian inspiration in a city as booming and squalid now as London was then. But when Dr Margaret Campbell performs an autopsy on one of his victims, the results send the investigative team reeling. The police, the media and a horrified public are baying for blood, and Campbell's partner, Detective Li Yan, is the detective responsible for delivering the killer to them. However, the Ripper knows exactly who's after him, and when he writes Li a personal letter, the case - and Li's life with Margaret - begin to drastically unravel. Only one thing is certain: to save himself and his family, Li must find out who the Ripper really is.
