In the first murder notice, a male colleague died at home inexplicably. The reason is that there is a conflict between the husband and wife, and the wife has been planning for a long time.
The second murder notice, the female boss died at the dinner party. The cause was long-term alcoholism and respiratory failure. The third and fourth time... Yan Shuang didn't know why she was involved in this unsolved revenge case. She was just a conscientious and transparent person in the company.
She always felt that there was a shadow behind her... staring at her in the darkness.
