Unfinished: Yes!

You think you are seeing the truth. But the truth is looking at you too. Shen Muyuan, director of the Ninggang Repertory Theater, died under the lifting stage of the rehearsal hall three days before the premiere. The scene was the setting of the play "Shadow Catching" - an old house that had been cut open vertically, with all the rooms exposed, like an anatomy specimen. Shen Muyuan was lying under the dissected house, with a broken neck bone and a copper button on his right hand side. Engraved with branching pattern and worn number "029" on the reverse. On the stage, he used prop blood to write a skewed "four" character. Detective Chi Yuan looked at it for a long time and realized that it was not a number. It is the beginning of the word "Yes". The first stroke stretched out a long tail - halfway through writing, someone pulled his hand away. He wanted to identify the murderer's name, but only finished the first drawing. There were six people who went in and out of the rehearsal hall that night: the deputy director, the male lead, the female lead, the stage designer, the lighting engineer, and the stage manager. Surveillance shows that no one can commit a crime within the time of death. Everyone's alibi was impeccable—or so it seemed. Until Fang Shiyuan discovered that someone walked out of the picture wearing the clothes of the deceased and came back wearing another person's clothes. Alibis are interchangeable. The copper button was torn off the murderer by the deceased's own hands. The murderer may have never left the mirror. "Shadow" is the name of a play and the name of this murder case. It's about a person discovering another person in his own shadow. Shen Muyuan arranged it into a drama. Someone staged it as a murder. ——And what Fang Zhiyuan wants to find is the person who comes out of the shadows
