On a starry night, Wey became a major suspect of the Hengcheng police for a serial murder case. When he was interrogated, he had not eaten for nearly 20 hours, suffered from unbearable stomach pain and was in a trance. The three victims were all her high school alumni, and evidence at the scene - a figure that resembled her in the surveillance, fingerprints on the murder weapon, and biological tissue in the dead man's fingernails - all pointed to her, but Wei Yi insisted on her innocence and believed that she was framed.
At the critical moment, Gu Feng, a provincial special consultant and double-degree doctor, arrived. He is not only Wei Yi's high school classmate, but also the person she has had a crush on for many years. Gu Feng relied on his professional ability and started with the details: he pointed out that the person under surveillance was not Wei Yi. Combined with the escalation of the murderer's criminal behavior (from impulsive killing to cleaning up the scene to destroying the corpse), he profiled the real murderer as a woman aged 25-34, 165-170cm, left-handed, and living in poverty, clearing some of Wei Yi's suspicions.
The case also involves an old high school case from many years ago: a robbery case involving Zhao Yihui, Su Li and others, which resulted in the death of Wei Yi's parents in a car accident. Wei Yi and Su Li had a long-standing feud, and Su Li had teased her many times in high school; she and Gu Feng also had many past memories, from when Gu Feng sent her to the doctor after she fainted at the sports meeting, to when they reunited on the streets of Orlando, the two had an undercurrent of emotion.
As the investigation deepened, Officer Ling discovered that there may be more than one person involved in the old case, and Gu Feng's name appeared in the transcript but was crossed out. At the same time, Wei Yi wanted to recruit Lin Ruo, a high school classmate, to join the company, but Gu Feng noticed that Lin Ruo was corrected to be left-handed, which vaguely matched the characteristics of the real murderer. The story intertwined suspense and emotion, laying out more mysteries to be solved.
A sweet suspense story, not bad
