A Last Goodbye on 'Lie to Me' (VIDEO)

Dr. Cal Lightman can read the truth -- or the lack of it -- in anyone's face. But on the latest episode of 'Lie to Me' (Mon., 8PM ET on Fox), Lightman must use his truth-reading methods for the most important purpose of all: conveying a man's last message to his wife and child.

[Spoiler alert.]

Dr. Lightman (Tim Roth) is called in to investigate a case involving a policeman who was shot in a federal housing project. After the injury, the cop is completely paralyzed -- and can only communicate by blinking his eyes. Lightman interprets the dying man's reactions to his questions -- and manages to solve the crime. But then, the policeman is about to expire from his injuries, and Cal must use his skills to convey a final dying statement of love.
