This time they're on a tour of Europe with their down-to-earth uncle John Merrick.The benevolent uncle and his nieces meet mysterious and sinister Victor Valdi, his daughter Tato, and a pretend nobleman, Count Ferralti, who fancies Louise. The story revolves around travel and kidnapping, and the subsequent adventures of the three young girls, told in Baum's own inimitable style that keeps us at the edge of our seats.
