Walt Disney's the Phantom Blot #3

Via a newspaper ad, the Phantom Blot enlists the Beagle Boys to spring him from prison and assist him in his criminal schemes. Together, they succeed in taking Uncle Scrooge’s money bin, but abandon it upon learning that Scrooge is focused on protecting a preposterously greater treasure. A treasure that leads Scrooge, the Phantom Blot, and the Beagle Boys to medieval times, and a confrontation with the dreaded Black Knight.
