don't always believe the clues
great game but has flaws. Sometimes the clues will misguide you and say that Anna is not in the area but if you check she might be there. I suggest to just keep track on which areas you've visited and which one's you haven't. Check everything in every area and move on if she's not there. By the way, I found Anna one time and she hanged herself. However, when I approached her she mysteriously revived herself. Just thought it was funny.
