Replying...
Intro. You broke into Sarah's apartment after you got out of jail. She was wrongly accused and you want to get back at her. You hid and waited. She finally got home and disappeared into the shower. You sneak in, first take out all your things, clothes, towels and so on, then you take the big knife and come up to her from behind, turn off the light and have the knife ready at the height of her face when she turns around.
