You begin looking at some shelving units, one of which has a globe and an hourglass on it. Turn to your left until you see the arched wooden entryway. Go ahead out of that into a circular atrium of sorts and turn to the left, taking the hallway immediately to the left of the one that you're exiting. Down that hall you should see another, smaller, circular atrium. You're going to cut directly across it to the door just beside the mirror, and once you are through there you are going to continue straight through the bedroom into the open archway on the left. That is a door actually, it was just hard to see the door from further away. You should step into a closet, a walk-in closet with a window on the other end of it to the one you're entering, just step up to that window, right above the little cabinet drawers thing, and once you're standing looking out of that window, you're done.
