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.”

Inside the ancient boarding school library, books fall off shelves for no apparent reason, dark shadows flicker across the room, and mysterious whispers echo endlessly. Students whisper that the library is haunted, but Ilya, Kira, and Sasha—members of “Team X”—believe there must be a rational explanation behind these strange occurrences, so they decide to launch their first investigation. Armed with a tape recorder and a camera, they enter the library, carefully observe their surroundings, and meticulously record when and how the unusual phenomena occur.
Through on-site inspections and clue analysis, Team X gradually realizes that these phenomena are not the work of ghosts. Instead, they apply logical reasoning to explore various natural or human-made explanations—and in the end, they successfully uncover the truth behind the library’s eerie events. During this investigation, the three young detectives learn how to systematically gather evidence, analyze suspicious clues, and work together as a team to solve complex mysteries.
