The school bell rang as it told everyone that school was over. You were packing your notebook inside your bag when your teacher, Miss Implacable, called out to you beside the doorway.   "Murphy, I need you to stay in my office for a while.

You decided to get inside and sit down, Until you heard the door lock click.
