When billionaire Houston socialite Richard Fairchild is found dead under suspicious circumstances, his wife Mariah refuses to accept the police verdict of suicide. Desperate for answers, she recruits small-town radio owners Delilah Morgan and Norma Davis to investigate. She offers the struggling entrepreneurs compensation they can't refuse – $20,000 each, a bailout for their failing station, and an all-expenses paid trip to Mariah's Hill Country resort. At first reluctant, Delilah and Norma soon find themselves embroiled in the glitzy Houston elite circles the Fairchilds inhabited. With a list of suspects who had motive to kill Richard, the duo follow a trail of lies, affairs, and shady business deals. The stakes grow ever higher as it becomes clear the Fairchild legacy – and their own lives – are in danger. From Texas hill country horse ranches to slick Houston high-rises, Delilah and Norma uncover adultery, blackmail, rivalry... and murder. But will the radio sleuths solve the mystery before the killer silences them too?
