Campbell McBride is now working for her father Bill as a private investigator in Murray, Kentucky. Xina Harrison wants them to find out what is going on with her aunt, Katherine Taylor. Katherine is a rich, reclusive author, and she has resisted letting Xina visit her for several years. Xina arrived unannounced, and Katherine was upset and didn't want to let her in. When Xina did gain entry, she learned Katherine fired her longtime housekeeper. She noticed that a few family heirlooms previously on display have disappeared. Xina is afraid someone is stealing from her aunt or influencing her to give them her money and valuables. True Blue accepts the case, and the investigators follow a twisting path to the truth.
