You decide to try entering the house through the cellar.
You dart across the yard, without attracting to much attention from the security guards. Though, you are a bit worried about getting into cellar without making to much noise. You stare at the doors and mentally sigh. There's no way you're going to open the door without making a noise unless you get your hands back. However, you really would prefer to be something that blends in with the darkness right now.
You wait until after the security guards pass the cellar, then quickly crawl out from the backpack straps. You then crawl inside, and pull out the Book of Beast. You look over your shoudler once, to insure that the guards have not returned, then open the book, and cast the Half Shape spell.
You transform, into an anthropomorphic raccoon. You quickly put the books in the backpack, and put the backpack on, open the cellar, and slip inside, remembering to close the doors behind you of course.
The cellar looks relatively typical. Lots of dusty old boxes in storage, old furniture, shelves filled with junk that may or may not be antiques, and some girl wearing only a pair of jeans being chained to a wall by some large brute holding a gray book. Wait, what was that last one?
You look back at the far wall.
Sure enough, there is a young girl chained to the wall. She appears to be close to twenty two, and resembles the stereotypical large breasted dumb blond. Her dress consist of a pair of jeans, and nothing else, no shirt. The man who chained her to the wall probaly did it for his own pleasure. And, he seems to be to distracted by her, to notice that you've entered the cellar.
Of course, something else of interest is the gray book the man is holding. It could be one of the seven books.
You could try to save the girl, but it may draw unwanted attention. However, it could result in you getting another book.
