Who killed Mrs White?

Hasbro, owners of Cluedo. And she is being replaced with Dr Orchid…

For the first time since 1949, Hasbro is changing the core Cluedo game, knocking off one beloved character and replacing her with another.

Long-time housekeeper Mrs. White will no longer be part of the main game; instead, Dr. Orchid will be joining the ranks of Colonel Mustard, Miss Scarlet, and Mrs. Peacock.

Dr. Orchid marks the first major change to the Cluedo series since it launched, and with her introduction, the other five suspects have been given youthful revamps for the new set (minus Mustard, who remains significantly older).
