Hello girls. I want to play a game. All of you are injected with slow-acting poison for which only I have the antidotes. As you can see, your dance instructor, Ms.Young is lying dead on the floor of the classroom you all are in. I want you to find who killed her, and, listen very carefully, the culprit is one of you. If you can find who the person is, the antidotes shall be bestowed upon you. However, as you all should be aware by now, if you fail to reach the answer in time, this room shall be your graveyard. Heed my warning though, the doors and windows are locked tight and there is no way for you to break through and escape. The only way out is find the killer. Live or die. Make your choice. Let the game begin.
