Trixie Belden and the Mystery of the Emeralds (1965)

A mystery in which Trixie and the gang try to find an emerald necklace from the time of the Civil War, which is hidden in Virginia. ( )

My favorite book in the series! Of course, I'm a sucker for secret passages and missing jewels- both of which this book contains :) ( )

I loved this series when I was growing up; I thought Trixie was a lot more fun than Nancy Drew, and these were some of my all-time favorite books. I read them as an adult, though, a few years ago, and found that they haven't, IMO, stood the test of time well. They are obviously dated, and there are some messages that I don't think are appropriate anymore (mostly the way Trixie is treated differently - and often poorly - because she's a girl). ( )
