As Sherlock Holmes continues his rise back into pop culture prominence, through everything from a potential threequel to the Guy Ritchie/Robert Downey Jr. movies, and BBC's hotly anticipated third series of 'Sherlock,' we've turned to CBS' own modern adaptation 'Elementary' for our deduction fix. Despite earlier claims to the contrary, it seems 'Elementary' is preparing to introduce Sherlock's greatest nemesis in "M." but is Vinnie Jones really that famed literary antagonist we're all speculating?

Far be it for us to question the executive producers of CBS' modern Sherlock Holmes procedural 'Elementary,' but upcoming episode "M." is looking more and more like an introduction to Sherlock Holmes' most famous enemy, that of the infamous Moriarty. Previously, producers Rob Doherty and Carl Beverly had expressed a desire to hold off on the famed character, instead placing Sherlock's father as a shadowy figure of the show's first season.

Now, CBS has released its first promo of upcoming episode "M.," set to introduce UK star Vinnie Jones as a British criminal possessing history with Sherlock, his "greatest enemy" with ties to fellow Sir Arthur Conan Doyle character Irene Adler. The episode's title and the hype could certainly wind up a red herring, but "greatest enemy" and proximity to the original literary canon certainly seem like strong indicators.

Check out your first look at Vinnie Jones in upcoming 'Elementary' episode "M." below, and give us your theories in the comments!
