Donald Duck #33/1967

In "Het spook van de Notre Duck," Oom Dagobert Duck’s new vault proves to be more than just a secure storage spot—it’s tied to a mysterious tune. When the fife that opens it vanishes from the Cathedral of Notre Duck’s wishing fountain, Donald, Kwik, Kwek, and Kwak follow a trail of eerie music, chasing a shadowy thief through the cathedral’s twisting halls. But as they close in, the very walls seem to conspire against them, trapping the ducks in a labyrinth of secrets and echoes.
