It is a face! It sent shivers down my spine! see.... above my shoulder in the window!! I rang the door bell 3x, it is like he is looking out to see who is there! and it gets better. I recognised the face! I purchased a book on the history of Monte Cristo and the face in the window resembles the original owner Mr Crawley! I have uploaded a photo of him, have a look then go back to this pic see what you think.
