Has Patrick Jane (Simon Baker) regained the upper hand in his cat-and-mouse game with Red John on The Mentalist?

Who is Red John? Vote in our poll!

At the end of last week's episode, Jane was given an important clue by Red John's latest victim, right before she died: Red John has a tattoo of three dots on his left arm. But simply forcing the five remaining suspects to roll up their sleeves may be easier said than done.

In this clip from Sunday's episode, exclusive to TVGuide.com, find out how Jane plans to use the new information to his advantage and possibly lure Red John into a trap.

The Mentalist airs Sundays at 10/9c on CBS.
