Caffeine is a Killer…After surviving two murders, and two months in business, bookstore and coffee shop owner Riley Morgan expects everything to go well. It’s August in the town of Cedar Grove, South Dakota. Summer is coming to an end, but there is one last hurray with the local Cedar Grove Apple Festival and Fair. It proposes to be a good occasion for all. Riley’s launching out his new Spiced Chai latte and Apple Cinnamon Scones. There is trouble on the horizon though. His old college roommate and rival in everything during those four years, Evan Johansen, has decided to open up a coffee shop in town. Riley’s landlord and nemesis, Brent Larsen, seems in full swing of this. Riley hates Caffeine Crush, because it’s just another trendy coffee shop. It makes matters worse when Evan is found dead in his shop, with a cup of Riley’s new Spiced Chai Latte nearby and this happens right after Riley is seen arguing with Evan. It will take the help of his best friend Connor, the nosy baker lady next door, his police officer girlfriend, and his trusty pitbull Duke to figure this mystery out.
