I'm playing this game, but haven't gotten to any tunnels yet. However, I noticed in the walkthrough that I should check the letter on the back of Ned's picture in Nancy's bedroom. Ned picked up the picture, but can't find a way to turn it over. Moved the cursor all around, but nothing happened. How can these Nancy Drew games keep stumping me??? I have Nancy's keys, examined everything in the room and got the fingerprint kit. Any suggestions?
