The Phantom of Nantucket

Nancy, Bess, and George are on Nantucket to visit Bess' friend Jenna and attend a exhibit opening at the whaling museum. When the girls get to the museum, a threatening banner has replaced the welcome sign. As the threats increase in severity, Nancy becomes more concerned about Jenna's safety than the ruined exhibit.
