She was a most wonderful woman for prowling about the house. How she got from story to story was a mystery beyond solution. A lady so decorous in herself, and so highly connected, was not to be suspected of dropping over the banisters or sliding down them, yet her extraordinary facility of locomotion suggested the wild idea. Another noticeable circumstance in Mrs. Sparsit was, that she was never hurried. She would shoot with consummate velocity from the roof to the hall, yet would be in full possession of her breath and dignity on the moment of her arrival there. Neither was she ever seen by human vision to go at great pace.
-Charles Dickens, Hard Times
