You're starting on a staircase. To your right is a large window with stained glass in the middle of it. To your left, you'll see the stairs going up. Follow the stairs up. At the top of the stairs, you're going to come into, what looks like a library with a long table in the middle. Walk between the table and the wall on your right, along that carpet. Go toward the far end of the table. You're going to stop before you hit the second chair from the end. So, once you're between the second chair from the end on the right side of the table, and the bookshelf, you're done.
