Mafia 80. Chronicles in Plasticine.

Haha )) Shall we conduct a graphological analysis? ^^

I think Ment is the culprit; at least, if we try to decipher the clues in a way that both options are plausible, there were no other convincing candidates besides him.

Didn't I seem like a maniac to you yesterday?

Kosh is unlikely to be the culprit; that would be too risky.
But her innocence hasn't been proven either. She could very well be any kind of virus that doesn't draw much attention. Plus, the protection she had yesterday surprised me personally.
