I cut a hole in the drywall for the secret room, but it was too dark to see. So I decided to break the window. I broke one of the panes and pulled on the curtain. It just ripped and fell it was so old. I couldn't reach the latch on the window, so I got a hammer and busted out the sashes and cleared the rest of the glass so I wouldn't get hurt. Then I climed in. There wasn't much in there but dust and an old TV. It must have been a bedroom as there was a closet. There's one t- shirt that says "Lin Pac" on it. The room is good sized. I think with a new door and window, paint, varnished floor it will make a useful office.
