When George's mum asks Bess, George, and Nancy to help her cater a benefit for the library, everyone is on board.

The event is a Jane Austen-themed party, and George even agrees to wear a dress for the occasion.

But it seems like the party isn't everyone's cup of tea.

The bed-and-breakfast where the event is being held has been plagued by vandalism.

Someone is breaking teapots, making a mess, booby-trapping the staircase, and generally terrorizing the old couple that runs the place.

No one can figure out how the mysterious intruder is getting in and out of the house.

Can Nancy solve this case faster than getting to the bottom of a cup of Darjeeling?
