The writer gave us one too many clues. The Chief of the who CBI is the guy. Near the end of a recent episode, he quoted a line from a William Blake poem. The bald headed guy who has replaced Hightower informed Jane that the quote was a William Blake line when Jane asked. No big deal there. BUT, guess who wrote the poem "Tiger Tiger" burning bright??? WILLIAM BLAKE. Ergo, the boss is either Red John's inside guy, or he is actually RED JOHN. I am betting he is Red John. Cheers!!!
