The Murderer Is Being Serialized

At three o'clock in the morning, Interpol Zhou Yan received a murder case. The deceased was a taxi driver, and there were no witnesses at the scene. However, there was an anonymous novel on the Internet. As early as 72 hours ago, the occupation of the deceased, the location of the crime, and the red button that the police had not disclosed yet were written down. Everyone believes that the author is the murderer. The police have just started to investigate, and the novel is updated again: "The second deceased has arrived and he is just outside the cordon." What's even weirder is that the real-name information of the account that published the novel actually belongs to the first deceased person. Thereafter, each chapter corresponds to an upcoming case. Is the author causing death, recording a crime, or is he seeking help from the police in this way? Zhou Yan must find him before the novel reaches the end - because Zhou Yan's name has appeared in the latest chapter.
