The outlook is not so good for Cass’s psychic shop, Mystical Musings. With winter winds discouraging tourists from riding the ferry from Long Island to Bay Island, Cass hopes to draw in more customers by hosting a murder mystery weekend, complete with a séance, in a supposedly haunted mansion. But Cass begins to lose her spirit when her ex-husband shows up, along with his fiancée—Cass’s ex-best friend. Then, after one of the guests is found dead, a blizzard blows in, trapping everyone inside with a murderer. Now Cass must divine who did the deed before her reputation and her livelihood fade away.
