Lisbon is about to meet her villainous match.

On this Sunday's episode of The Mentalist, Henry Ian Cusick (Lost, Scandal) will debut as someone creator Bruno Heller describes as a "charming and powerful man," an individual only Lisbon suspects of truly dastardly deeds.

"Lisbon's search for vengeance is triggered by a huge and traumatic failing on her part," Heller teases to TV Guide. "In her eagerness and aggression to catch this guy, she puts other people in harm's way."

Although Cusick is not featured, watch the official CBS preview now for "If It Bleeds, It Leads."
