Electromagnetic Pulse Apocalypse

A clever move, considering I'm suspected in every game, and votes are cast quite easily. Did my colleagues give me a hint?

Your role will be revealed. She had no reason to lie. If you're a peaceful player, the Mafia/Maniac who accused you for no reason won't be around at night anymore. And that's beneficial. It's a good trade, considering there are more peaceful players.
Execute Arandor. I don't understand those who don't want to vote. One of them is definitely Mafia or Maniac. We should check.

What if a second Investigator shows up?

If he does, it's better if he stays silent. There's no Doctor protecting him. No one is stopping him from killing Mona at night. Tox could have done it. =)

Then the Doctor was healing against the Mafia, and the Maniac was killing.

Hmm. Why would the Maniac kill? I think it's the Mafia. What's the point of the Maniac using a regular kill? With a blood kill, he could have killed both the target and the Investigator if he came to the target. And roles are revealed anyway when there are only 10 people left in the game. And if the Maniac had used a blood kill, which is a more logical move in this situation, it would have been written that Vis was a victim of the Maniac.
