Eliminate two Rouge's lairs from the Outer City.
Scarlett will need to visit the Guard Captain of the Outer City and ask for work. He can be found patrolling the northern part of Trading Center area of the Outer City. Look for a guard in a blue tabard walking about between the Garrison and the northern-most Trading Center tower.
The Captain suggested Scarlett find the bandit's lair by waiting until just before dawn and following them back to their den. That doesn't actually work (rogues tend to just evaporate come first light), and a stakeout would be pretty boring, anyway. Use the Quest Map to find their lair any time of day. One is at the end of the main street through the Backstreets, and the other is behind the Old Temple. Each door is protected by an extra tough lock (not that it will phase Don and Nesto's ghosts; just a couple of extra twists.)

Inside each lair, Scarlett will find one of the Rogues standing guard in the hallway. After she dispatches him, the door at the end of the hall will have to be smashed down using her heavy war hammer or battle axe. Inside, she'll find three enemies waiting: two Rogues and one Rogue Master. Dispatch them with extreme prejudice.
When Scarlett attacks in the second lair, the last Rogue Master will attempt to negotiate. He claims if the rogues are wiped out, something worse will only take there place: corrupt city guards. Scarlett can leave without fighting, or wipe them out, her choice. (They are right, and once Scarlett has removed all the rogues, soon the nighttime streets will be terrorized by Marauders instead.)
There is ample treasure in each lair. Hey, they have pie!
