Buried Treasure... In My Own Attic(1994)
(The fourth book in the Bubble Gum Gang series)
A novel by Cynthia Blair
A trunk full of beautiful old dresses and hats sets Carla on a buried treasure hunt. The only clue is a poem stuck between the brittle pages of an old diary, but it's definitely a mission for the Bubble Gum Gang--three junior high school misfits who know how to solve mysteries--but where do they start, and, even more important, what will they find when they're done?
