The Mentalist Adds Henry Ian Cusick As A Guest Star In Season 5

In its four previous seasons, The Mentalist has dealt with criminals from many different backgrounds and with all kinds of different agendas. What the show does not do all that often is introduce potential criminals with multi-episode story arcs. In Season 5, Lost alum Henry Ian Cusick is joining the cast for a special three-episode guest stint that may or may not leave the man with a criminal rap sheet.
