Books with title Xavier Ox's Xylophone Experiment

In this third and exciting new book in the new Countdown Mysteries™ series, we catch up again with the three young detectives who together use their combined detective skills, and high-tech devices, to solve mysteries and crimes in their town of Anchor Bay. A desperate thief hits the Anchor Bay Art Gallery, apparently stealing nothing at all, and leaving the gallery staff and police totally baffled. Then their new friend’s precious musical instrument is mysteriously stolen from the concert hall just days before an important concert, leaving Roly, Nine and Charlie with no idea that one situation is inextricably connected to the other in some way. Can the members of D.I.G. come together again and use their combined detective skills to save the day… and all before the countdown clock runs out?
