Okay, so what's the deal with the basement window and grate. Some say this is evidence of an intruder...some say it is evidence of the contrary. What say you? I understand their was a cobweb on the grate...does anyone know if this was fact of fiction? If their was a cobweb on the grate, could the grate have been moved and replaced without disturbing the web? Is the grate significant? Why? Why not?
