Donald Duck #32/1967

When Scrooge Duck unveils his new vault—accessible only by playing "My Bonnie Lies Over the Ocean" on a fife—he sends the tune soaring into the depths of the Cathedral of Notre Duck’s wishing fountain. But when the fife vanishes and a mysterious black-clad figure begins playing the same melody, Donald, Scrooge, and the nephews Kwik, Kwek, and Kwak find themselves chasing shadows through ancient stone halls. As the cathedral’s secrets stir, the pursuit leads them into a trap they never saw coming.
