1. The devilishly mafia-like behavior that I noticed on the very first day.
2. Mafia-like reactions to accusations in the following days.
3. Overall unwillingness to answer questions due to the fear of making a mistake somewhere – peaceful players are happy to answer such questions because it gives them the opportunity to confirm their side, and there is nothing difficult about answering – because they don't need to lie, just tell the truth about their opinion and don't worry. The mafia, on the contrary, are afraid of not seeing a trap and therefore are more likely to be afraid to answer.
4. Avoiding answering the last question. I asked it to finally confirm your side. And you confirmed my suspicions – you gave an incorrect answer because you were afraid of being exposed.

At least because there are three mafia members out of nine players.
