The Tarot Murders.....duh!!! This is not the first clown to leave behind a Tarot card. In fiction or real life. I say it's phony and tailor made to mislead (idiot) Moose and other investigators.
That's an interesting take... I was just speculating that the thing about not reporting the card to the media was an act of defiance by the police even though they feigned anger over the 'leak.'
