I haven't felt this way since I figured out that the killer in all of those "Murder She Wrote" episodes was Jessica Fletcher. Of course she was the killer, she was present every time someone was murdered.
I always thought Mrs. White did it. From when I was a child playing my first game of Clue, my first guess always included was Mrs. White. I would confidently announce: "Mrs. White, in the Kitchen with Poison." Of course it was Mrs. White, she was the cook and therefore in a great place to put poison in someone's food. And she had motive, she was a poor working class woman surrounded by affluent posers like Mr. Green or Colonel Mustard.
Now, she is dead, killed off in order to introduce a new character. Is this news? Yes, it is. Here how Boston Magazine put it: "Board Game Clue Kills Off Mrs. White, Introduces Dr. Orchid." Yes, Dr. Orchid, a plant biologist with a doctorate will take the place of a lowly cook, the only working class character in the game.
