When a mysterious man, beaten and tortured, stumbles into the police precinct asking for JD, then dies before he can divulge his secret, a series of events are set in motion that will put the couples’ detecting power to the test and Harper’s life in grave danger. Soon after, Aubrey Lowen, Harper’s second cousin, is found severely beaten by the side of the road. Hospitalized, he hovers between life and death as Harper heads to Keeneland’s backstretch to keep an eye Lowen’s head trainer, Henley Smythe, who seems up to no good. As Harper tries desperately to uncover the culprit and help Aubrey’s wife Millie save their once-successful Thoroughbred farm, a dangerous character from Harper’s past shows up on the backstretch. Amid the dark pool of danger swirling around Harper, JD announces that the Feds have stepped in, preventing the couple from continuing their investigation. Undeterred, the two work under the radar to stop a killer bent on destroying the Lowen legacy and anyone who gets in the way. As murder and greed haunt every step they take, the couple knows that buried deep in Keeneland’s chaos the killer lies in wait—but uncovering the murderer just may cost Harper her life.
