In the short story The Shadow on the Glass, Lady Cynthia Drage is one of the guests of Mr and Mrs Unkerton. She is a middle-aged woman with “a hard face and a liberal allowance of make-up”. During the events of the story, she has a parasol with her, which is described as being "the newest thing in parasols". She uses it to gesture as she is talking, tapping Mr Satterthwaite smartly, and waving it to greet newcomers.
Lady Cynthia has a vast knowledge about people and scandals.
