Infiltrate the Manse
Escape the manse
Talk to Mirabelle first in Gran Soren and receive a set of Royal Armor. Head to the Duke's Manse northeast of Hillfigure Knoll and wear your disguise. Leave your other equipment and keep your weight down so you can freely loot whatever's inside the manse. Enter through the front gate and make sure you're carrying ample amount of curatives since you'll be exploring the whole manse alone.
Explore the area until you reach the duchess. It's rather small so you wouldn't have problems navigating the place. After the cutscene, escort her until you reach a locked gate near the entrance. She'll unlock it and continue downstairs until go through the underground corridors. Make sure to save often at this point. You'll run into a bunch of bandits so deal with them quickly before they turn their attention to Alenoire and hurt her.
After clearing the enemies, continue forth and you may have to carry her and jump across the gaps to proceed. Your pawns will regroup with you eventually so continue exploring the area until you reach the exit.
