"I have thirty days to decide whether to have an affair…." This line, uttered by Carolyn O’Keefe, lures P.I. Kristin Ashe into following and investigating the woman Carolyn plans to pursue. From the start, Kris has misgivings about the work, but her unease turns to rage when Carolyn reveals the object of her interest. The more Kris learns about Carolyn O’Keefe and her strange past, the more frightening the results. At the same time, Roberta Franklin, a real-estate developer, has hired Kris and Fran Green, the feisty ex-nun, to determine whether the mansion she wants to convert into condos is haunted. The elderly owner says "no," her daughter disagrees, and her adolescent great-grandson, Flax, turns out to be a natural at ghost hunting. When Kris, Fran, Flax, and a paranormal investigator spend a night in the dilapidated structure, they discovered there’s as much complicated drama in the real world as there is in the spirit world.
