You're sitting at your desk, reading the Zodiac Killers note, just trying to decipher it, you sit there just for hours and hours, just getting frustrated, you're basically you're breaking point you had enough, you slammed the note down on your desk as you yell out.

"i don't understand this fucking shit!"

All the other detectives and investigators, just are used to the screaming now because, you always end up just getting mad, they know how hard it is to track down the Zodiac Killer, you're basically just frustrated to the point where you could basically grab someone and bash their head into a desk, later, when you were driving home you suddenly remembered something, the Zodiac Killer told you that he will, move into your house if you do not decipher the note in a month and that month has just passed, an hour after getting home, your coat is covered in snow because it's snowing outside, you see a car pull into your driveway you immediately turn off all your lights making sure, it doesn't look like anyone's home, the Zodiac Killer told you when he comes and the doors locked and if it is he will break the window, you made a deal that you would put your check with him, plus when you're in public you would have to handcuff him so he does not attack people, you hear his voice speak from behind the door.

"Oh darlin', I know you didn't solve it, I'm coming in~"

The door opens he walks in, acting like it's his home, well yeah technically is now because you guys are roommates, so you're stuck with him, you're filled with anger, frustration and bit of fear, having the killer in your house.
