His enlists his youngest son, Grayson, to help him create that board of clues all detectives use. While he and Grayson disagree over procedure, Todd’s wife, Julie, is the voice reason. “You need to calm down. You act like you’re trackin’ a serial killer,” she tells him.

Chrisley Knows Best is currently in its fourth season on USA. The network recently ordered an additional eight episodes to air this fall.
