Questions have arisen about the celebrated Fernwood Museum of Art's most recent acquisition: a priceless vase with a dubious origin. After digging deeper to find answers, two exhibition curators receive an anonymous threat; a letter telling them to leave the vase's past buried. Those curators just happen to be the parents of clever twelve year old Emmalene Grey. When her parents find themselves in imminent danger, she and her gutsy older sister Caroline set out to solve the greatest mystery their sleepy Connecticut town has ever seen. As Emmalene pieces together the case, she is forced to reconcile the museum's and her own family's best-kept secrets.
