About this book
The Boxcar Children attend an Invention Convention at the home of an eccentric artist known for her whimsical, one-of-a-kind clocks. The clocks chime loudly at every hour, especially at midnight. But the clocks aren't the only noise the kids hear โ something or someone is tapping in the night. Is someone inventing trouble for the convention?
