22. The Pirate's Promise

Tracking a cursed foghorn, Micki and Ryan arrive at an isolated community. Initially unbeknownst to them, the local lighthouse keeper is using the foghorn to summon up the ghost of pirate Angus MacBride, who kills his descendents in return for revealing more and more of his hidden treasure to the keeper. Ultimately the keeper discovers that he is the last descendent of MacBridge, and the pirate captain completes his crew at last.
