This series comprises five books: “The Ghost in the Library,” “The Mysterious Whispers,” “The Mystery of the Locked Room,” “The Secret of the Old Wardrobe,” and “The Mystery of the Cursed Chest of Drawers.”

During class breaks, strange sounds began emanating from the school’s broadcasting system, including students’ names, meaningless phrases, and menacing whispers saying, “You’re all about to face a terrible disaster.” While most teachers and students dismissed it as a simple equipment malfunction, Team X sensed something was amiss and decided to investigate the source of these mysterious sounds in depth.
Team X started by examining the broadcasting system’s equipment and studying how the school’s PA system works. They interviewed students and teachers who had heard the various sounds, meticulously recording when and what was being broadcast. Through data analysis and on-site investigations, the team discovered that the sounds were not random—they were deliberately generated by someone. In the end, they identified the individuals responsible for creating the sounds and uncovered their methods, ultimately solving the entire mystery.
