The Mystery of Locked Rooms

Thanks to a breeze coming from behind the brick wall, the Deltas realize that it is fake. Sarah, West, and Hannah pull the bricks out to reveal a tunnel, and Hannah volunteers to go first. She crawls through the passage and points out a message on the wall that reminds them that there is only one correct direction in the Library Room. The tunnel gets narrower and narrower until it seems to reach a dead end. Sarah and West, who are following Hannah, start to get worried, but Hannah can open a passage that leads them back into the library through one of the bookshelves. There, they realize that the room must contain four exits, one for each cardinal direction, but only one will lead them to the next room. The slide, marked with a “W,” represents the Western passage.

Back in the Library Room, Sarah, West, and Hannah decide to try using the rotary phone they noticed earlier. The phone’s plate shows letters instead of numbers, and when Hannah picks it up a recorded voice tells them to enter an answer.
