Midnight Book and Movie Mystery

Introduction: Late at night, a bizarre case occurred in the century-old "Qinglan Library" - a precious ancient book, Night Tales Notes, disappeared out of thin air in a sealed display case. The surveillance video showed that no one entered the exhibition hall that night. What's even weirder is that the librarian Lin Mo received an anonymous letter on the night of the incident, with only one line on it: "At twelve o'clock at midnight, the book will come back by itself." After the police intervened in the investigation, they discovered that there was a dusty unsolved case hidden behind the library: Thirty years ago, a young female writer mysteriously fell to death here, and the last thing she read during her lifetime was this night story notebook. As the investigation deepened, Lin Mo and criminal investigation consultant Lu Chen discovered that a book "disappeared" every ten years in the library's catalog, and all the missing books seemed to be related to a mysterious "Midnight Reading Club"...
