P.I. Billie Bly is hired to investigate a haunted house producing screams and entities of dancing light her client thinks are ghosts.
Billie reluctantly takes the case because her client is paying her double her rate. It would be easy to chalk up the ghosts to her client's overactive imagination and the fact that a haunted house fundraiser is being held there the week of Halloween.
When she sees things she can't explain, she is sure someone is plotting to scare people away from the house. The problem is, she can't figure out how and why they are doing it.
Each step she takes plunges her deeper into danger and the thing that scares her most may be her saving grace.
