Xu Heshu, a talented suspense writer, has a secret habit: on page 13 of each manuscript, he uses invisible ink to record the true sinful inspiration behind the story.
Lin Zhihan, a top forensic doctor, believes in absolute rationality. She was ordered to investigate a series of serial murders that imitated the plot of the novel. All the evidence pointed to the writer Xu Heshu, but she discovered that the murderer left the provocative number "13" at every scene.
They were supposed to be "dead enemies of the truth" in the parallel world, but they were forced to intersect due to a series of serial murders that perfectly replicated the novel. Lin Zhihan was the only one who discovered that all the scenes had the same strange mark "13", and all the evidence pointed to Xu Heshu.
The two people who didn't trust each other were forced to join forces. One decodes the human heart's code from the yellowed invisible pages, and the other verifies scientific evidence on the cold autopsy table. Reason and imagination collide here, and what they are chasing together is a ghost reader who knows all the "truths on page 13".
However, when the last hidden page was revealed, they discovered that what the murderer really wanted was not imitation, but "correction." He is writing the two of them, as the protagonists of the final chapter, into an irreparable tragedy.
——When fiction begins to devour reality, the only ones who can break the situation are the puzzle maker with a pen and the solver with a knife. They become each other's only accomplices in a desperate situation.
Intent: When fiction and evidence must corroborate each other in order to arrest the reader who used the story to kill people, the author who wrote the book and the forensic doctor who wielded the knife signed the same "common guilt" contract.
