Time to get even. Seek out the rich scholar who's promised to help you with your map, and confront him with the pirate leader's accusations.
This mission must be accepted after completing Past the Point of Subtlety within the mission instance.
Go back to your nation's starting town to the same location where you started off this storyline (in A Man of Wealth and Taste) and confront the rich man in his house. He is a level 10 Boss. After some talk, he will turn hostile and you have to defeat him in a swashbuckling duel.
- Kill the rich man
WARNING: After you accept this mission and you still have not gotten your reward for completing the earlier The Winning Bid, there is a workaround turn-in mission called Settling Accounts, which is given by their Assistant located back in their home. This is not a bug, but intended timeline behavior.
