The Spotlight Clubbers create stone rubbings of Civil War-era tombstones for a summer school class on the Civil War. Cindy has chosen the tombstone of Serafina Winslow, who died in 1862. Then, at the neighborhood yard sale, Cindy locates a box of interesting-looking old photos and frames and miscellaneous papers. When she takes it home with her, she discovers Serafina Winslow's journal inside! Things get even more mysterious when Cindy finds a sketch of her neighbor's missing locket in the journal. What does the long-deceased Serafina Winslow have to do with the recent disappearance of the locket? Leave it to the Spotlight Club to dig up the answers!
