Mafia 31. Twilight Dances.

Surprisingly, I currently trust Gil the most. The Mafia wouldn't act like that. And he's genuinely trying to logically and discreetly resolve the situation, rather than simply throwing someone under the bus. Hos also writes well, but he seems more suspicious.
Regarding the candidates for execution: Rimple is absolutely against it. Not only is he poisoned, but the clue is also – the key here isn't its simplicity, but the fact that it's a bit off, and I agree with Hos on that. We can assume that the fang is a planted clue, but it's also too simple (it's practically next to the main clue in the profile), and there was no reason for the Mafia to expose the archer so blatantly. I'm leaning towards the idea that the fang and the four elements are a single clue pointing to one detail in the profile.
Slonysh – I voted because there were no other candidates, but I think eliminating her is a big risk, and I'm not sure she isn't being set up by the Mafia.
Neira – I initially wanted to join Gil, but I realized that it's no less risky than with Slonysh.
However, Lizard seems like a pretty good candidate to me; the clue against him turned out to be quite complex, but right now, it's the best interpretation. Although he still won't be executed. By the way, where's Rimple with the proof of the white lizard?

Actually, I have my own suspicions about the Mafia, based on the notes from the second night, their behavior, and other things, but revealing them would either lead to a modkill or a knife/arrow in the back at night.

Learn to read between the lines.

Although I can't do it myself :(
