The Killer's Code 》A Jeff the Killer Fanfict...
Kacey Madison excelled in everything she did. She'd graduated top of her class a semester early, held her school's fastest track record since she was a Freshman, and had four colleges offer her full-ride scholarships for her singing. She was perfect. But she had a dark side. By day she was a model citizen, but by night she was a serial killer operating under the alias K.C.K.
With her stunning good looks and her sharp wits, she'd deterred the police from suspecting her, but when a strange, pale boy witnesses her murder a man in an alley and threatens to reveal her, she is forced to play his game.
