*WARNING, HUGE RED JOHN SPOILERS AHEAD*

Hi,

My theory is an unpopular one, but don't just hit the red thumb.

I am certain that Red John is Marlon Dingle from Emmerdale.

Now, I know that this seems unlikely because Emmerdale and The Mentalist are different TV shows, but a collaboration is not out of the question. I also believe a few of you will have come up with this theory too, so please, let's share our ideas.

There are a few things that make me certain of this:

1. The voice;

We know that Red John has a high pitched voice, and I think you will agree that in this clip Marlon Dingle's voice is also rather high pitched, when he wants it to be: http://www.youtube.com/watch?v=GwbXArwp19Y

2. Law enforcement connections;

In the video clip above, we see Marlon is a member of the local law enforcement. We know Red John has influence over the CBI and other local law enforcement agencies. It would make sense if Marlon gained this influence by working his way up the ladder of the FBI or Homeland Security - making friends on the inside.

3. Appearance;

From this picture, and the video above, you can see that Marlon matches Rosalind Harker's description exactly. He would make the perfect Red John. When he smiles, his face also bears a strong resemblance to the famous Red John smiley face.This should convince you that Marlon is Red John. http://files.list.co.uk/images/2012/07/16/9df367ec6a7771d4854bc0b5fccbbfa5f3dab10d.jpg

4. "He is Mar"; http://www.blogcdn.com/www.aoltv.com/media/2009/01/mentalist-heisman.png

This CLEARLY implies that the man Red John killed was trying to write "He is Marlon". This almost proves Marlon Dingle is infact Red John by itself.

5. "Gonna Red Mill";

Marlon Dingle is an anagram of "Gonna Red Mill", i.e. Marlon is going to paint the mill red. The mill actually refers to the barn where Red John ( or should I call him Red Marlon! ) painted his smiley face!

6. "Tyger Tyger";

As we know, the line "Tyger, Tyger" is repeated often by associates of Red John. In this picture, we see Marlon wearing an orange and black shirt. Which animals have an orange and black striped coat? You guessed it, tigers! http://www.emmerdale.org/emmerdale/Picture_Gallery/thumb_size/marlon1_dedication.JPG

Thanks for reading my theory and I hope this has enlightened you. Maybe now you can all stop posting theories about the "7 suspects" and we can collect enough evidence to prove, once and for all, that Marlon Dingle is Red John!
