The Secret Timetable

                            In **“The Secret Timetable”**, an ordinary Monday morning at school turns into a thrilling mystery when 9-year-old Milo Mertens notices something impossible: a whole lesson has disappeared from the official school timetable. At the strict and highly organized Regelberg Elementary School, every minute is planned, every rule is posted, and every student is expected to follow the schedule without question. So when Milo spots a strange gap between classes, he knows something is very wrong.

Together with his clever friend **Fina Fuchs**, who loves logic and patterns, and his chaotic but lovable friend **Turbo**, Milo begins to investigate. What starts as a small curiosity quickly becomes a full-scale **school mystery adventure**. The three friends discover a second, hidden timetable marked with a mysterious stamp and linked to something called **“Project Double-Timetable.”** Suddenly, students are being sent to extra lessons in rooms that officially do not exist, scanners are reporting “unplanned presence,” and the school seems to be changing right in front of their eyes.

When Turbo receives a notice for **extra class in Room 102**—a room no one has ever seen—Milo and Fina realize they are dealing with more than a timetable mistake. Hidden doors, secret corridors, suspicious announcements, and strange time gaps lead the trio deeper into a puzzling system of control. As they follow clues through the school hallways, they must stay one step ahead of the strict **Inspector Order**, a rule-obsessed authority figure who seems to know more than he admits.
