And here, I'm even more confident than with the clue against Slonysh, because in her case, you could still say that the earring and the tiara are slightly different things, but here, the fact that the compass didn't point north can only be explained by this... there's a very high probability that WishmasteR is the Mafia... IMHO... Perhaps rescind Slonysh's execution and execute WishmasteR.
