Sophia:It was Colonel Mustard in the library with the candlestick.
This is a reference to both the classic board game and the cult-classic film Clue. Both have characters such as Colonel Mustard, Miss Scarlett, and Mrs. Peacock. They also both involve having either the players of the game or the audience trying to figure out who killed Mr. Boddy, who died before either the game or movie began. There are many rooms in the mansion, along with many weapons.
