The traveling carnival has made its stop in Sinful and everyone is ready for thrilling rides, challenging games, and most importantly, funnel cake. But when a man is murdered in the funhouse and Emmaline LeBlanc is knocked unconscious so the killer can escape, the good times are over. Carter is beside himself wanting to hunt down the man responsible for putting his mother in the hospital, but he can't investigate when he's related to one of the victims.

Palmer Reed was well known as a boy by most everyone in Sinful for being a sneak, a liar, and sometimes a thief. As an adult, he continued his reign of underachieving and mostly making people angry wherever he went. Now he's a state police detective and is assigned to the case, but Fortune knows that to get Carter the answers he needs, Swamp Team 3 has to take on the investigation. As they dig deep into the confusion and lies that surround the murder, they uncover a secret that could devastate Carter and Emmaline, but Fortune is determined to discover the truth...whatever that may be.
