The Mentalist premieres its third season on September 23.

Soon afterwards, viewers will be a new character, one with a close connection to Patrick Jane.

According to a CBS casting notice, the drama is seeking an actor to play Jan's brother-in-law. This individual is a con man and blames our favorite fake psychic for his sister's death - but he'll need to make things right when he stands accused of murder.

No word yet on when this episode will air. Got any suggestions for who should take on the role?
