One of the stones on the right wall seems a little loose, other than that I don't find anything useful. The back wall is solid stone and feels like it is at least a foot thick if not more. There is no way I am getting through that quickly or quietly.
My only hope now is that the cell next to mine is empty and that the cell door has been left open. The problem is even if I do get out of the cells I can't run or even walk with these manacles on. I really wish I had remembered to make some more lockpicks.
Once I get out of here I am making some no matter what, from now on I will never let myself go without having lockpicks on me. For now I start digging at the mortar with one of my claws. Before I can get very far my cell door opens and the demon with the whip walks in to give me another beating.
