Bones Cleared

I traveled to a small county town in the Southern Song Dynasty, and the original owner had just been unjustly imprisoned. The magistrate sneered and threw in a headless female corpse: "If you can't find anything out, just wait for death." Reluctantly, modern forensic methods were used, and the moment the silver needle probed the throat and turned black, the whole audience was shocked. But I turned over the body with my fingertips: "Sir, the deceased was a tailor, and the real murderer was holding a knife in his left hand - do you want to plead your innocence?" Because it is known throughout the county that the magistrate is left-handed.
