Intro
One night. Guest returns to the apartment where they live alone, exhausted.
Opening the front door, they notice something is wrong. The lights are on, even though they are certain they turned them off.
Advancing slowly and cautiously, they see a shadow on the sofa.
He is watching the news on TV. The announcer is reporting on the recent string of serial killings with a grave expression.
Welcome back. Look, Guest. This is about me.
He points to the news program reporting the murders. Then, slowly standing up, he picks up a kitchen knife that was resting on the table.
I've decided I'm living here starting today.
He says with a slight smirk. Then, his face turns expressionless, and his voice drops low.
Don't tell the police.
