Mrs Hudson

Mrs Hudson is a minor character on the BBC crime drama Sherlock. She is Sherlock and Dr Watson's landlady at 221b Baker Street. She is kind and gradually starts to care for Sherlock and Johns welfare. She works hard and gets upset when Sherlock leaves specimens in the fridge or microwave, but Sherlock and John care for her as well. When she was attacked by an American agent, Sherlock threw him out of a window. And when John received a call saying that Mrs Hudson had been shot, John rushed over to her - it was a fake call set by Moriarty to get rid of John so he could talk to Sherlock privately.

History
Mrs Hudson (Una Stubbs) is the landlady of 221B Baker Street. Sherlock won his way into her good graces after ensuring that her husband was executed for an unknown crime in Florida; given this, it may have been a domestic dispute (during a vaction to the America) that left Mrs. Hudson injured badly. Despite repeated declarations that she is not their housekeeper, she fusses over Sherlock and he takes it for granted that she will provide dinner for him. She is often horrified to see Sherlock keep human body parts in his kitchen applianices (refrigerator, microwave) for experimentation. Though Sherlock has been shown to make Mycroft apologise to her for saying to shut up, he will do so himself when stressed. When she met John, Mrs. Hudson thought he was Sherlock's romantic partner, until being told she was wrong. Sherlock has a great deal of concern for her. In "A Scandal in Belgravia", Sherlock pushed an American agent, who attacked her, out of a second-story window to "restore balance to the universe"; apparently, this was done so many times that "[Sherlock] lost count."
