Back Cover SummaryEdit
In an old history book of Stoneybrook, Kristy finds a name that really catches her eye: Christina Thomas. The more she reads about Christina, the more excited Kristy gets. It turns out that Christina, who was an heiress, disappeared in 1863, when she was just seventeen. Nobody knows where she went — or what happened to the fortune she took with her.
Could someone with such a similar name be an ancestor of Kristy's? And would that make Kristy an heiress, too? One thing is for sure: the Baby-sitters are going to track down some answers — and maybe even the fortune!
