The Complete Carl Barks Disney Library #[6]

Synopsis

Uncle Scrooge and the ducks go to Scotland to find the treasure hidden in the walls of the old McDuck castle, and there they encounter a "ghost" that is invisible except for the shadow cast by its skeleton. The "ghost" soon steals the treasure and traps the ducks on a balcony a hundred feet above the ground, but the nephews get down safely and find a secret entrance to the castle through an old graveyard.
