Mafia 91. Experimental Redemption.

Well, let's just say I see the "maniac" problem differently. Obviously, one of the pair is Neyra/Sezam. But I have to say, the second one is more likely than the first. Sezam doesn't really look like a mafia member; she's too bold, but she definitely looks like a maniac.
Ples and Demerol are mafia members, yes.
