Intruder (Nancy Drew Girl Detective Series #27)

When George's mom asks Bess, George, and me to help her cater a benefit for the library, we're all on board. The event is a Jane Austen-themed party, and George even agrees to wear a dress for the occasion. 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--and that's where I come in. I plan on solving this faster than I can get to the bottom of a cup of Darjeeling.
