Mrs. Digby is the Redfort's housekeeper. She has known Ruby Redfort since she was an hour old. She enjoys preparing food for Ruby and her friends, and listening to Chime Melody. No one is sure how old she is, not even herself. She is also very strict when she has been ordered to do something but is very nice to Ruby. In the last book she is basically the hero as she is the one who pushes Casey Morgan (Buz) of the edge, causing Casey to fall to her death. She is very fond of all the Redforts as well as Hitch, who stated that he was getting quite good at making a "Digby Club Sandwich", Mrs Digby's signature dish that everyone, especially Ruby and Clancy, enjoy.
