Bestselling novelist Alexander McCall Smith introduces readers to a delightfully funny pair of heroes--and the tricky villain who's always keeping them on their toes. Max and Maddy Twist have a flair for solving crimes. You might even say it's in their blood. That's because their parents 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. In Max and Maddy and the Chocolate Money Mystery , when a Swiss businessman asks for their help in catching a bank robber, Max and Maddy can't wait to take on the case. But little do they expect to find themselves chasing a gang of thieving St. Bernards! In Max and Maddy and the Bursting Balloons Mystery , 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?
