Agartha

You decide to go to the police and tell them the hypothesis that you have to "a person in agartha that you met is killing people" and you know it because You received the text message with already 3 names of dead people.
The police inform you that this cannot be true because, in the news they reported it as an accident. in order not to scare people in reality, they were suicides.

Congratulations, you are in the eighth final. They won't take you seriously in the police. (8/14).
