News of Peter and Elise Andersen's latest adventure has traveled fast—all the way from Helsingør to Copenhagen and King Christian. The twins are thrilled when the well-loved Danish monarch invites them to visit him at his palace. But on the train to Copenhagen, Peter and Elise have a frightening run-in with a gruff German who is extremely protective of his travel bag—and its curious-looking contents. Soon, the mysterious man begins to show up everywhere the Andersens go. The German' s keen interest in an antique key Peter finds adds to his suspicions about the man's motives. What can he possibly be up to? Convinced the German is a threat, Peter turns spy and discovers that King Christian may be in danger! But will Peter and Elise be able to warn him in time?
