Secrets of Glenville

I don't understand why it's Isaac and not Koshu; I can't say anything about that. Logash is playing aggressively; I would also be checking him out.

Many people, including you, Kitz, suspect Plesen because he needs money (description). But you also need money, right? So, based on the role description, you're mafia or a maniac.
