If not the Partridge, so is the sheriff. Haffner next episode will be eliminated as a suspect, and many people will cry. If it's a list:

I believe in that order V

1 - Partridge (It was difficult now)
2 - Sheriff
3 - Bertram
4 - Raffner
5 - Stiles
6 - Smith

(My opinion)

If not, Bruno Heller changed the script, 

And this thing about "tiger tiger" is wrong, I hope they do not spoil the ending. And that Red John is not just a simple member of this organization.

( Sorry my English.)
