After you see her in the jail run up the stairs and go to the left, run along the wall and
jump on the ledge of the window, move along to the right side then jump in between the two
wooden posts, slid down then wait to sneak attack the monster below, once you kill him,
finish off the other. Once their dead you'll have to push the big basket onto the floor
switch then move one to the next area, once again killing the monsters. Once you get to
the last area you'll see the door switch located one the wall, run up and slash at it, she
should be realsed. Once she's out she'll shoot down the basket for you and you can open up
the last door and you're into the next room.
