The Skeleton Key Mystery
Anthony VanArsdale, Gertrude Chandler Warner
The Aldens are visiting a small town known for its fall festival, and while Grandfather is off taking in the fall colors, the children try out the town's newest attraction—a Halloween escape room! The Aldens love solving the puzzles to get out of the room, and they don't mind the spooky theme. The problem is, someone—or something—is making things downright scary for other customers!
