Back from their adventure on the high seas, Jaundice and Kale are settling into a quiet life in Dullsville, just the way they like it. The tea is tepid, the oatmeal is tasteless, and the socks are ripe for darning - that is, until Aunt Shallot shows up and reveals herself to be anything but the dull relation they were expecting.
Instead, she tells her nieces that she is Magique, Queen of Magic, and that she's on her way to a big show and is in need of two willing assistants. As Magique and the Bland sisters board the Uncanny Express, they meet a cast of mystifying characters. And when Magique goes missing, it's up to Jaundice and Kale to solve the mystery - with the help of famous detective Hugo Fromage.
