[@VKAllen] As you investigate you notice that there are old, thick vines that run up the length of the manor towards the west side (closer to the edge of the cliff, you can't see the edge as the walls block it off). There are three balconies across the 3rd (and top) story of the manor. There are doors opening out to each balcony, the set of doors closest to the west end (about ten feet from the closest patch of vines that could support a grown adult) is open, the breeze coming off the water has white curtains fluttering in and out with the whims of the wind. Alternatively, the roof has several chimneys, one of which looks like it may fit one of your more lithe companions.
