I think maybe I have to take another look at that whole "kept woman" thing.
— Ms. Hudson to Watson, "Snow Angels".

Ms. Hudson works as a maid and sometimes assistant to Sherlock Holmes. Holmes indicates that she has an Oxford don's knowledge of ancient Greek, but she's a complete autodidact. She consulted with Holmes on several cases when he worked for Scotland Yard. Holmes also calls her a "muse" as she consistently finds herself in the company of powerful men in crisis. Watson notices her Adam's apple indicating that Ms. Hudson is most likely a transgender woman.


Season One

Watson first meets Ms. Hudson at The Brownstone as Holmes as offered her a place to stay while she recovers from a break-up with David Renkin, a powerful executive. Ms. Hudson was Renkin's kept woman. With the power out and a snow storm pending, Hudson helps Watson make a fire when they are interrupted by Renkin pounding on the door. Hudson tells Watson to let him in but this results in them arguing. After returning from a case in the snow storm, Watson is pleasantly surprised to find the Brownstone cleaned. Holmes approves of Ms. Hudson's method of organizing his many books. The next day, Ms. Hudson leaves for her cousin's and Watson learns that he's hired her to clean the Brownstone weekly.
