One sentence summary: In the countdown to the anonymous death notice, the funeral home forensic doctor found himself involved in a perfect criminal loop that spanned fifteen years. Each corpse was a secret code pointing to the real murderer.
Main plot: I am a resident medical examiner at a funeral home and deal with death every day. Until he received an anonymous text message accurately predicting an upcoming "accidental" death. In order to prevent the tragedy, I intervened in the investigation, only to find that the deceased was a key figure in an old case fifteen years ago. Since then, death notices have followed like a shadow, and each deceased person is related to the serial disappearance case that was covered up that year. I had to look for clues in the autopsy, deal with my partner who was a criminal police officer (actually a pawn to monitor me), and make my way through the cold atmosphere of the funeral home. In the end, it was discovered that I was not only the puzzle solver, but also the carefully designed "last key" - my deceased relative was the first victim of the serial case, and the murderer planned for fifteen years just to complete the "cleaning" of the last accomplice through my hands today, and make me bear all the guilt. The truth is hidden in the abnormal death details of each corpse, and the time it takes to solve the puzzle is the countdown breath of the next person who is about to die around me.
