The small town of Snowberry Creek, Washington, is gearing up for the Halloween Festival, and naturally, Abby is on the planning committee. As part of her duties, she's picking up a pumpkin order from ornery farmer Ronald Minter. But what she finds instead is the farmer in the middle of his corn maze with a knife in his back. The police suspect a homeless veteran named Kevin Montgomery, who was seen arguing with Minter when the farmer accused him of trespassing and stealing pumpkins. Abby's tenant Tripp Blackston, a veteran himself who’s been helping Kevin, is sure he’s innocent. Together, Abby and Tripp follow the twists and turns of the case to corner the corn-maze killer—before someone else meets a dead end.
