The sixth season of The Mentalist has a tagline: “Red John: The Final Chapter.”

So that’s even more confirmation that Red John will indeed be unmasked this season. Below, the first promo is all about the hunt for the show’s mysterious serial-killer villain, an operation that’s now down to seven suspects.

Here in the teaser with Patrick Jane (Simon Baker) conflicting with Teresa Lisbon (Robin Tunney) followed by a moment that strongly suggests that Red John may have captured her. Check it out below, the drama returns Sunday, Sept. 29. And afterward, see our Q&A with showrunner Bruno Heller on why capturing Red John isn’t necessarily the end of the show.
