In Season Four of The Mentalist, Simon Baker returns as Patrick Jane, consultant with the California Bureau of Investigation (CBI), solving the state's toughest homicides. After gunning down serial killer Red John during Season 3's explosive finale, the question remains -- is the man Jane shot really Red John? When it comes to The Mentalist, the truth is often elusive. And with a new boss, puzzling new cases, and Red John never far from his mind, Jane will need his keen skills of observation, manipulative theatrics and smooth charm to sidestep the system that stands in the way of the truth.
