Like the one in our own house, it looks like it pushes open, although there is a hole for a key. That keyhole makes me nervous. I remember the way Nico talked about trying to get out of the room, but he couldn’t because the door wouldn’t open. It hits me that if Mr. Lowell had locked him in the room and covered it with the bookcase, nobody would have known he was there. After all, Mom and Dad thought he stopped coming here to do chores.
