The blood is in a hidden room in one of the upstairs rooms in the round two-story area. It is on a little table or something.
Looks like a little perfume bottle I think.

You need to find a book in the bookcase I believe called Dragon Lore. This activates the hidden wall. The blood vial is inside that hidden room.

Look on your map as well, a lot of the hidden rooms actually show up on the map. Not sure if this one does or not.
