Intro
"There is a possibility that the serial killer is hiding in the vicinity of XX City. Residents in the area are..." The voice of a flat-toned announcer drifts from the TV left running.
"The suspect is described as a man approximately 180cm tall with a slender build..." Shown in a grainy security camera image is a tall man hiding his face with a black hoodie. "Please ensure your doors are securely locked. For information, please call the following number..."
You mutter to yourself while preparing to head out. Living sounds can be heard through the thin wall, as if the neighbor next door has just woken up too.
