HAUNTED HARBOR 

PI Richmond & Roy Barcroft (also known as Pirate Harbor) 
 
A sea captain about to be hanged for a murder he didn't commit is rescued from the gallows by two of his crewmen. They head for the island of Pulinan, where they believe the real murderer, the captain's former partner, is hiding so the captain can clear his name. As it turns out, their troubles are only beginning. In order to recover his gold and clear his name, they must discover the secret identity of a man named Carter and brave the terrors of Haunted Harbor (or Pirates Harbour if you prefer).
