In the quaint town of Arden, nestled among sprawling apple orchards, secrets ripen beneath the surface. The annual Apple Harvest Festival takes a dark turn when the body of Henry Foster, the town's wealthy and feared orchard mogul, is discovered-poisoned, clutching a half-eaten apple. As Detective Iris Locke arrives to investigate, she finds herself entangled in a web of grudges and rivalries stretching back decades. Each suspect harbors a grudge against Henry, and everyone seems to have something to hide. With whispers of toxic deals, illicit affairs, and shadowy threats, Iris soon realizes that in Arden, no one is as innocent as they appear. And the deeper she digs, the more she uncovers a town rotting from the inside out-a town where one bad apple has tainted everything around it. As she edges closer to the truth, Iris must decide how far she's willing to go to expose it... before the killer strikes again.
