Max & Maddy and the Bursting Balloons Mystery

Max and Maddy Twist have a flair for solving crimes. You might even say it's in their blood. That's because their parents once ran a thriving detective agency--until the notorious Professor Claude Sardine shut them down. But now Max and Maddy are ready to pick up where their parents left off. When an eccentric balloonist enlists their help in finding out who is sabotaging a hot air balloon race, Max and Maddy not only take the case--they take to the air! But will they be able to find the culprit before their balloon becomes the next target? Bestselling novelist Alexander McCall Smith introduces readers to a delightfully funny new set of heroes--and the tricky villain who's always keeping them on their toes.
