Mrs. Hudson is a fictional character in the Sherlock Holmes novels and short stories by Arthur Conan Doyle. She is the landlady of 221B Baker Street, the London residence in which Sherlock Holmes lives.^[1]

Mrs. Hudson appears or is mentioned in many Sherlock Holmes stories, though her appearances are generally brief, and little information is given about the character. She has been made a more prominent character in multiple Sherlock Holmes adaptations in film, television, and other media.^[2]

Mrs. Hudson is the landlady of 221B Baker Street, the London residence where Sherlock Holmes and Dr. Watson live in many of the stories. In the short story "The Adventure of the Naval Treaty," Holmes says "Her cuisine is a little limited, but she has as good an idea of breakfast as a Scotchwoman,"^[3] which some readers have taken to mean that she is Scottish. Other than one mention of her "stately tread" in the novel A Study in Scarlet, she is given no physical description or first name, although some commentators have identified her with the "Martha" in "His Last Bow".^[4][5]

In the first Sherlock Holmes story, A Study in Scarlet, there is a landlady of 221B Baker Street, though her name is not given. The landlady is identified as Mrs. Hudson in the following story, The Sign of the Four.^[1] At one point in "A Scandal in Bohemia", Holmes calls the landlady "Mrs. Turner", rather than Mrs. Hudson, which has caused much speculation among Holmes fans.^[6] It has been suggested that Mrs. Turner was substituting for Mrs. Hudson or that Holmes or Watson mistakenly used the wrong name, though it may have simply been an error by Doyle, since the name Mrs. Turner also appeared in an early draft of "The Adventure of the Empty House" but was corrected to Mrs. Hudson.^[7] When Holmes is in retirement in Sussex in "The Adventure of the Lion's Mane", he says he is living with his "old housekeeper", which some readers believe is Mrs. Hudson.^[1]

Holmes tells Watson in "The Adventure of the Empty House" that his sudden return to Baker Street three years after his supposed death "threw Mrs. Hudson into violent hysterics". In the same story, Watson notes that their old Baker Street rooms are unchanged due to "the supervision of Mycroft Holmes and the immediate care of Mrs. Hudson".^[8] Mrs. Hudson also places herself in danger to assist Holmes in the story, by carefully moving a bust of Holmes every quarter of an hour to fool a sniper, Colonel Sebastian Moran, into thinking the bust is actually Holmes.^[9] When Moran fires his gun, the bullet passes through the bust and hits the wall, after which it is picked up by Mrs. Hudson. She expresses dismay that the bust of Holmes was spoiled by the bullet and presents the bullet to Holmes.^[8]

There is no mention in the stories of Mrs. Hudson's husband. It has been suggested as a possibility that she was never married, since the title "Mrs." was used in the Victorian era as a respectful title for high-ranking domestic staff, regardless of marital status.^[5] While no relatives of Mrs. Hudson's are identified in the stories, she shares her surname with a character in "The Adventure of the Gloria Scott" and another in "The Adventure of the Six Napoleons". There are also characters in "The Boscombe Valley Mystery" with the surname Turner, a name which may or may not be connected with Mrs. Hudson in "A Scandal in Bohemia".^[1]

Watson describes the relationship between Holmes and Hudson in the opening of "The Adventure of the Dying Detective":

Mrs. Hudson, the landlady of Sherlock Holmes, was a long-suffering woman. Not only was her first-floor flat invaded at all hours by throngs of singular and often undesirable characters but her remarkable lodger showed an eccentricity and irregularity in his life which must have sorely tried her patience. His incredible untidiness, his addiction to music at strange hours, his occasional revolver practice within doors, his weird and often malodorous scientific experiments, and the atmosphere of violence and danger which hung around him made him the very worst tenant in London. On the other hand, his payments were princely. I have no doubt that the house might have been purchased at the price which Holmes paid for his rooms during the years that I was with him. The landlady stood in the deepest awe of him and never dared to interfere with him, however outrageous his proceedings might seem. She was fond of him, too, for he had a remarkable gentleness and courtesy in his dealings with women.^[10]

In The Sign of the Four, she worries about Holmes's health after hearing him spend the night pacing up and down.^[1] In "The Adventure of the Naval Treaty", she apparently plays along with Holmes's dramatic reveal of the missing treaty to Mr. Phelps by serving Mr. Phelps a covered dish with the recovered treaty inside.^[9] Mrs. Hudson is displeased on the two occasions Holmes is visited by a dirty group of Baker Street Irregulars, expressing "disgust" when the Irregulars arrive in A Study in Scarlet and "dismay" when they appear in The Sign of the Four.^[9] In "The Adventure of the Speckled Band", Mrs. Hudson is woken up early by the appearance of a client for Holmes and, by the time Watson is up, has "had the good sense to light the fire" according to Holmes.^[1]

She is the landlady of 221B Baker Street, and also appears to perform various tasks such as preparing meals. Holmes praises her "excellent" breakfasts in "The Adventure of the Naval Treaty" and "The Adventure of Black Peter". She serves curried chicken in "The Adventure of the Naval Treaty" and woodcock in "The Adventure of the Blue Carbuncle". She sometimes escorts visitors up the steps to Holmes's flat, such as Inspectors Gregson and Baynes in "The Adventure of Wisteria Lodge" and some sailors in "The Adventure of Black Peter". She also occasionally brings Holmes a card or telegram on a tray, for instance when she brings Holmes the card of John Garrideb in "The Adventure of the Three Garridebs" and a telegram in "The Adventure of the Dancing Men".^[9]

In addition to the page Billy, Mrs. Hudson employs a live-in maid at Baker Street. Watson hears the maid going to bed while he is waiting up for Holmes in A Study in Scarlet, and waits for the maid to bring him coffee in "The Five Orange Pips". She brings Holmes a telegram in "The Adventure of the Bruce-Partington Plans". It has been suggested that this maid could be the Mrs. Turner who appears in "A Scandal in Bohemia".^[1]

Though limited information is given about Mrs. Hudson in the original stories, the character has developed a popular image due to portrayals in adaptations and speculation in articles and books, according to a 2005 essay by Catherine Cooke. Cooke writes that Mrs. Hudson is "a nice, motherly individual getting on in years [...] At least, this is how she is usually conceived. It is a portrait perpetuated in numerous films and television adaptations: Minnie Rayner in the Arthur Wontner films, Mary Gordon in the Basil Rathbone films, Irene Handl in The Private Life of Sherlock Holmes, and Rosalie Williams in the Jeremy Brett series".^[5]

Cooke also adds that essays written about Mrs. Hudson have influenced the general conception of the character, one of the most influential being "The Singular Adventures of Martha Hudson" by Vincent Starrett, originally published in 1934. Starrett suggested that Mrs. Hudson's first name is Martha, and described Mrs. Hudson as a "housekeeper", though in the original stories she is only referred to as a "landlady", which is a separate occupation. Cooke writes that "most American Sherlockians until relatively recently seem to have accepted Starrett’s fancies," but adds that British Sherlockians were less likely to identify Mrs. Hudson as "Martha" or confuse her position as a landlady with that of a housekeeper.^[5]

Daniel Smith writes that, though few details are given about Mrs. Hudson in Doyle's stories, the character "has become one of the iconic figures of Sherlock Holmes's world" due largely to portrayals of the character in film and television. According to Smith, "Mary Gordon in the Rathbone films and Rosalie Williams in the Granada TV series did much to form the popular image of the landlady". Smith also comments that Gordon, Williams, and other actresses such as Irene Handl and Una Stubbs have provided "memorable portrayals of the occasionally tetchy but ultimately sympathetic stalwart of 221B" and helped cement Mrs Hudson's place in the public consciousness.^[2]

In the TMS anime series Sherlock Hound (1984–1985) directed by Hayao Miyazaki, Mrs. Hudson is depicted as a much younger woman in her early to mid 20s, and a widow of a pilot named Jim. In this incarnation, her full name is revealed to be Marie Hudson, and fitting with the theme of the characters being canines, she resembles a Golden Retriever. She normally stays behind at 221B Baker Street, but accompanies Hound and Watson on a few cases, usually any that involve something related to flight, and is shown to be a very skilled driver, pilot, and markswoman. She is once kidnapped by Professor Moriarty and his henchmen as a part of a scheme to defeat Hound, though Moriarty vows to never involve her in his schemes after she shows him kindness during the time she's kept as a hostage. Additionally, it's shown that most of the main male cast of the series (namely Hound and especially Watson) are attracted to her. She is voiced by Yōko Asagami in the original Japanese release and by Patricia Parris in the English-language dub.

In "A Scandal in Belgravia" when agents torture Mrs. Hudson trying to find a mobile phone, Sherlock repeatedly throws the agent responsible out of an upper-level window, and later states that "England would fall" if Mrs. Hudson left Baker Street. In "His Last Vow" her name is revealed to be Martha Louise Hudson (née Sissons), a semi-reformed alcoholic and former exotic dancer. Her "pressure point", according to Charles Augustus Magnussen’s information on her, is marijuana.

A transgender Ms. Hudson appears in the 19th episode of the US series Elementary, "Snow Angels" (2013),^[14] as an expert in Ancient Greek who essentially makes a living as a kept woman and muse for various wealthy men; Holmes allows her to stay in the apartment after a break-up, and she subsequently agrees to clean for them once a week as a source of income and to prevent Holmes from having to do it himself.^[14] She is portrayed by Candis Cayne.

Mrs. Clara (née Clarisa) Hudson is a much more developed character in Laurie R. King's series of novels focusing on the detective scholar Mary Russell. In this alternative extension of the Holmes mythology, the retired Holmes marries his much younger apprentice and partner. Russell and Holmes meet after the traumatic death of her family in California when she moves to the farm adjoining Holmes' Sussex home. Mrs. Hudson takes the young and emotionally fragile Russell under her wing, and Russell comes to think of her as a friend, a second mother, and a rock in the whirl of danger that always surrounds Holmes. The novel The Murder of Mary Russell (2016) tells Mrs. Hudson's biography over several generations, her meeting and bond with Holmes, and her ties to Russell. The novel appeared after the development of Mrs. Hudson's character in the BBC series Sherlock. As in that rendition of the character, Mrs. Hudson has a criminal past and initially met Holmes in unsavory circumstances, in this case when she murdered her father to save Holmes' life. Holmes buys the Baker St. house for Hudson and establishes her as his landlady. In typical Holmesian logic, this relieves him of the tedium of homeownership and explains both her forbearance with her tenant and his uncharacteristic affection for her. A skilled actress and con artist, she is comfortable with the criminals who inhabit his world and enjoys playing occasional roles in investigations in which an eminently respectable older woman might be needed. In this series, she is slightly older than Holmes (although Russell and Watson think she is significantly older), born in Scotland, raised in Australia, and an immigrant to England. She acted as a mother surrogate to Billy Mudd, Holmes' first 'Irregular', has one sister who lived to adulthood, and one illegitimate child of her own. Holmes states explicitly that the condition of her remaining in England and their relationship is that Hudson's life prior to the murder is never to be mentioned, that they must never have a sexual or romantic relationship, and that she know that her history as a criminal and murderer will always be present in his mind whenever they interact. To Holmes, Hudson represents a way of solving the ethical problem of what to do with someone who murders to prevent harm, but who may return to criminal activity. His manipulation of Hudson removes Hudson and Mudd from lives as criminals, keeps Hudson's infant from the workhouse, and provides Holmes with a housekeeper and intelligent ally.

In Sherlock Holmes' War of the Worlds (1975) it is suggested that Holmes and the younger Mrs. Hudson had a long-lasting love relationship, obvious to all but the naive Watson.
