Patrick Kloster is a character who appeared in Mr. Monk and The Genius where he murdered his wife for millions of dollars worth of life insurance. Being a Behaviorist, he can study the mind and actions of others and use them to his advantage, especially when winning at chess games. However, the one person he found challenging was Monk who was able to deduce that Tatiana's tombstone was switched with another grave. Because of his narcissism and superiority complex, he believes that he couldn't get caught and thought he was above the law and that everyone is merely a piece in a chess game, but was proven wrong by the Obsessive-Compulsive detective.
