Finders Keepers

Finders Keepers is a secondary quest in Dragon Age II.

Acquisition
After completing the Fools Rush In quest, travel to the Hanged Man. Isabela will tell you about Martin.

Walkthrough

 * 1) Find Martin in the back of the Hanged Man, where he will tell you of what he needs from you.
 * 2) Travel to the Docks during the day and speak to the longshoremen.

 * 6) If you tell Martin the location he will give you a discount for poisons for the rest of the game.
