Last night, "Diamonds Are Forever," the last Sean Connery James Bond movie, circa 1971, was on the TV. 

1) Diamonds were hidden by being put into a chandelier [a plot in The Mentalist, SEASON ONE Ep. 4  "LADIES IN RED"]

2)  The Bond girl was a REDHEAD

3) Played POKER in LAS VEGAS/most of setting was CALIFORNIA & LAS VEGAS 

4)  went to a CARNIVAL

5)  REDHEAD played a game where you shoot water into a CLOWN FACE

6)  And the villian had  a TWIN [made through plastic surgery]

7)  Hero is a cocky know-it-all who gets the best of everyone

I think Heller must have seen this movie a few times when he was a kid LOL -- though The Mentalist is FAR better than this lesser Bond movie.

BUT if Red John is anything like this movie -- then the villian is the guy with the TWIN:  KIRKLAND [which one, I do not know]
