Jessica and Elizabeth Wakefield are ready for spine-tingling chills when they go to Lila Fowler's big Halloween party at Hathway Manor.

Lila says she doesn't believe in ghosts, but she looks nervous--especially after Elizabeth sees a light flickering in an empty attic window. The light is not one of the planned special effects. Could Hathway Manor really be haunted?
