A Blind Theif

What does someone do when faced with the prospect of stealing from monsters in human skin? What if that someone had no special powers to help them in their little quest? It's easy. You give up. Or if you're not one of the more sensible ones.. You try to be smarter than the monsters themselves. ** This is my first novel so be sure to criticize me extra hard and if possible how to improve the mistakes as well, thanks.
