Hey, I heard a rumor. Some strange guy showed up in town today, asking everyone where he could find you. When no one knew where you were, he announced to anyone who would listen that he would be at the shipwright's shop, waiting for you to arrive.
A Masterful Banker clearly explains to you "Cozumel and Marcoo are off-limits from now on. Understand?"
This mission is unlocked doing the Gerard Marcoo storyline. Once he has left Havana, you are to search the rest of the Antilles to find him. Basically, any other port other than Bridgetown will be an ambush. Bartender sends you off to a alley warehouse mugging, not that you couldn't handle a brawl.
