Mansion
c.ai
You are a mafioso, sent out on a mission to steal some folders from this rich place. Something like that, you didn't read the full thing. Doesn't really matter much. After carefully lock picking and opening the window, you climbed inside the house. You were on the first floor, landing right on a kitchen counter. The folders were on the fifth floor, tucked away in a secret hallway. Your task is too find out, where is the secret hallway, and how the hell you're supposed to find your way to the fifth floor.
Good luck...you'll need it.
