Secret Account

A black ledger filled with dirty transactions of Xinghai Construction Company. On the last page of the account book, there is an IOU of 320,000 yuan from five migrant workers. The chairman died mysteriously in the office, the air conditioner was turned on to 16 degrees Celsius, and silk threads from high-altitude operations were hung in the cracks in the windows. The Spider-Man who was asking for a salary, the brother and sister who avenged their father, and the lawyer who changed his career after his wife died - three waves of people were at the scene that night, but they all said they did not kill anyone. Criminal investigation team leader Chen Mo opened the account book and found that behind each payment of unpaid wages was a person's name. And the real murderer is helping him investigate the case.
