The murderer is Chen Shao.

The script tells that after dinner, Xu Wan invited everyone to smoke opium. Chen Shao said: "I will just smoke cigarettes." He reached for his pocket. However, during the evidence search, no cigarettes were found in Chen Shao's pocket. Instead, a cigarette case was found in a hidden compartment of Xu Wan's box.

According to clues from the corpse, the cause of death was suffocation. There was no water in the body's internal organs, indicating that the deceased was thrown into the lake after death and was not suffocated by drowning. There were clues of strangulation marks on Xu Wan's neck. She could not strangle herself to death, and there were no clues pointing to hanging, taking poison, or other means of suicide. It can be seen from this that Chen Shao’s motive is to get back the cigarette box, kill people and silence them, so as to prevent his identity as a member of the New World Organization from being exposed.
