The Murderer Is Not at the Scene

Three months, three secret room murders. The deceased was tied to a folding chair. There were no external injuries on his body, and his face had the same kind of distortion - as if he was scared to death. There were no fingerprints, no footprints, no DNA at the scene. Criminal investigation captain Jiang Yanting has been working on cases all his life, and this is the first time he has taken the initiative to hire a psychological profiler. The person who came was called Shen Yanbei. He was young and spoke little. He stood in front of the whiteboard and looked at it for ten minutes, picking out details that no one had noticed. The case was solved. But there is another case involving Shen Yanbei - his cousin was killed fifteen years ago, and the real culprit has not yet been caught. All clues have been suppressed, changed, and hidden. To make matters worse, new cases and old cases began to face each other. Someone watched them in the dark for a long time.
