Mafia 21.

I want to consider the notes for now, skipping the snails.

2nd night

Based on the investigation, Neyra Drake has a negative status. Considering the block and 2 uncommitted murders, I believe we can confidently conclude about the type of her role.
With the report, your informant.
P.S. Tonight, I'm going to Aziral.

As we can see, the note is indeed confirmed by visiting Aziral, which means it is true.
But I was much more interested in the reaction of some players to it, when they didn't yet know that the note contained a postscript about Aziral. Despite Neyra and Happy's obvious conformism, the latter vehemently rushed to deny the truthfulness of the note, diverting the discussion. Hermit did the same. Therefore, I believe that they belong to the same group.

Let's pay attention to Neyra's reaction. She constantly claims something like "town, you will be real idiots if you execute me, because you are making a mistake." Interestingly, she makes this claim in every setting – just remember the last one, where she was Death. It's silly to fall for such unargued statements.

3rd night

Aziral has a positive reputation and good apples in the garden. Today I'm going to Hermit.
Your informant.

truthfulness is undetermined

Aziral has a positive status. Yesterday's note about Hermit was planted by the Mafia. I have changed my opinion about Neyra Drake; she may be a Barbarian or a Pirate. Tonight, I will check Thorium.
With the report, your informant.
P. S. To avoid copying my style, I wrote the word "informant" with "щ" yesterday.

lie, because Thorium had no visits. Therefore, the note was planted to justify Neyra.

Summing up the overall logical conclusion, execute Neyra Drake.
