Max and Maddy Twist have a flair for solving crimes. Their parents used to be famous, international detectives before the evil Professor Sardine ruined their careers. Now they run an ice-cream parlour while people turn to their crime-busting Cluedo-champion children to solve mysteries. In The Chocolate Money Mystery, Max and Maddy set out to catch a bank robber. But instead of a dastardly thief, they find themselves hot on the trail of a gang of St. Bernards.
