Another Victory For The Mentalist.
17 March 2014 | by See all my reviews

"Grey Water" is another great episode from The Mentalist.....after "The Golden Hammer" all the episodes were better than the previous ones and this one was the greatest of The Mentalist 2 so far....Grey Water has two main story lines: A.The search for the killer of an anti-fracking advocate and B.The hunt for whoever is killing the former CBI members....the way both of these plots are handled at the same time was great...this episode is full of surprises and just as it makes you laugh sometimes...it will make you feel butterflies in your stomach..If I say anything more I might spoil the episode for you,so have fun and enjoy "Grey Water".
