Know Thyself

My cases aren't like normal cases. I find the secrets the occult world is likely to kill you for. Quit half way and you step into oblivion, misjudge and you might lose your mind. Paranoia is an occupational hazard. 

They say all roads lead to Rome and, in this case, so do all my clues. Nestled deep within the Vatican clergy—guarded by something with more tricks than Harry Houdini and possessing the moral conscience of a snake—are the answers I've been looking for, so long as I am willing to trade my soul. 

It's one thing to know when the antichrist has come, it's a whole other kind of crazy when he says he's your brother.
