The Perfect Crime: the Absent Murderer

Four horrific murders occurred in Linjiang City one after another. The heads and fingers of the deceased were cut off. The murderers committed the crime neatly and left no traces at the scene. The police profiled him as a male vendetta killer, and the investigation stalled. Real estate salesman Shen Yan accidentally got involved in the case and formed an informal partner with criminal investigation captain Su Wanqing.
