With Halloween fast approaching, Alex Harris, owner of the Always Prepared temporary agency, has her hands full keeping her assistant from turning the office into a house of horrors. But that's nothing compared to finding the body of one of Indian Cove's high society poisoned. All eyes turn to septuagenarian Robert Brissart. But Alex doesn't believe it for a minute fearing that the old woman was the intended victim all along and that another attempt will be made to finish her off. Alex needs to find out which member of the town's elite is the killer before they strike again. There's something sinister going on in Indian Cove and it's not just Halloween hi-jinks. The mystery comes to a frightening finale amid the jack-o-lanterns and ghosts on Halloween night when Alex discovers that there are more than just witches and goblins trick-or-treating in her normally peaceful New England village.
