Theory on the Fake List:
So we know that Brett Partridge has already been killed...
Next episode, there will be a murder at the Visualize Headquarters...
In the preview for the next episode, the dead man on the ground looks like it may be Jason Cooper of Visualize.
So what does that mean?
I think that Kirkland go ahold of Jane's black book (in the link below) http://images3.wikia.nocookie.net/__cb20121126092820/thementalist/images/6/6a/Tumblr_me32umpZrn1rgjl...
Kirkland has been on the hunt for Red John as long as Jane has.  He knows that Patrick is smarter than he is, and wanted to find out who Patrick had narrowed it down to...and when he searched Patrick's room, he found the black book.

Brett Partridge and Jason Cooper are BOTH on that list.  I think that this is the "Fake List" they were talking about in the previews for the next episode.
After Kirkland kills both Partridge and Jason Cooper, that's when Jane realizes what's going on, and tells everybody that someone has his fake list.
Kirkland finds out the list is fake, and takes Patrick hostage to try and get the REAL list from him...

I still don't know for sure who Red John is, but I think I may be right with this theory.  What do you think?
