The first episode of plot development
On the Mid-Autumn Festival moonlit night, tycoon Nie Chengjiang gave a big banquet for his new house. Unexpectedly, a bizarre murder happened in his new house. Chen Qiusheng, the deceased, was a well-known person in Shanghai, engaged in commerce and futures. When he went to the toilet drunk, his secretary He Kun and two men saw a hand with a knife sticking out of the mirror and stabbing Chen Qiusheng to death. The crime scene was blocked on the spot, and Qiao Chusheng, inspector of the patrol room, led the masses to the scene at the first time.
After investigation, it was found that there were no Tibetan organs at the crime scene, the walls were solid, the ceiling had no windows, and there was no escape route after the crime. This is a typical murder case in the secret room. After investigation, on the day of the party, Lu Yao, the manager of Sassoon Bank who had a dispute with the deceased, was listed as an important suspect and was arrested in the patrol room.
During the trial, Gao Fei, who returned from Cambridge, quickly concluded that Bai was an audit reporter with superb IQ. Qiao Chusheng urged Lu Yao to help him solve the mystery. During the investigation, Lu Yao not only cleared his suspicion, but also the truth behind the murder gradually surfaced.
