Mafia 20. Radioactive Dreams.

Ah, I keep thinking and thinking about the smokers... Veg was with them, and they killed Morny, then me. I don't think Veg himself would do that, so it must have been other members of the mafia). And I doubt it was the newbies (although Phoenix is a suspect), which means it was someone from the old guard, maybe someone who knows us well. So, based on my reasoning, I suspect the following people are smokers: Azi, Hermit, Phoenix... or maybe Nera instead of someone, since there was evidence against her). That's the situation.
Gur (due to his connection to the cosmos), Teng (same reason), Azi (again, the cosmos + light), Deriel (due to his skills)... are suitable for the role of the 13th.
