The Mentalist is casting for a new, evidently key character.

Based on the notice sent around this week, his name will be Sam Glenn and the CBS drama is hoping a "name" actor lands the role, which ought to appear on at least seven episodes. It looks like he'll have a connection to Teresa, as well as a possible rivalry with Patrick.

Here's a look at the complete casting note:

40-49, masculine, attractive, a California Bureau of Investigation Agent. He was Detective Teresa Lisbon's mentor as she was coming up through the ranks - in fact, they even dated for a while at one time. He is the head of a division that has been given the Red John murder investigation.

He is the one person who doesn't fall for Patrick Jane's charming ways...APPROXIMATELY A 7-EPISODE ARC. WE ARE LOOKING FOR A "NAME" ACTOR IN THIS ROLE. PLEASE SUBMIT ALL ETHNICITIES.
