When Marcie Ducasse, newly promoted associate editor of Roaming New England magazine, gets a call from Steve Rostow, an old college friend, telling her that the ghost of a girl killed twenty years ago on the night of her senior prom has returned seeking vengeance, she knows this is the right material for her “Weird Happenings” column.

As Marcie and Steve investigate further they find that one of the richest men in the town of Arbella, Connecticut, who was a suspect in the girl’s murder, is trying to hush up the ghost’s attacks. He would also like to keep Marcie and Steve from writing their story in order to protect his own political ambitions. As the attacks reach a murderous crescendo, it becomes clear that they can no longer be concealed, and Marcie and Steve are forced to unearth events that happened twenty years before, in order to understand who killed the girl on the night of her prom and who—or what—has returned to avenge her.
