Mycroft Holmes is a fictional character appearing in stories written by Sir Arthur Conan Doyle. He is the elder brother (by seven years) of detective Sherlock Holmes. He is described as having abilities of deduction and knowledge exceeding even those of his brother, though their practical use is limited by his poor physique and dislike of fieldwork.

The character has been adapted in various pieces of literature and media, including television series, movies, radio, and comics. He is also popular in culture, being mentioned by many works, which mostly reference his job, personality, or his relationship with Sherlock Holmes.



Possessing deductive powers exceeding even those of his younger brother, Mycroft is nevertheless incapable of performing detective work similar to that of Sherlock as he is unwilling to put in the physical effort necessary to bring cases to their conclusions. In "The Adventure of the Greek Interpreter" Sherlock Holmes says:

...he has no ambition and no energy. He will not even go out of his way to verify his own solutions, and would rather be considered wrong than take the trouble to prove himself right. Again and again I have taken a problem to him, and have received an explanation which has afterwards proved to be the correct one. And yet he was absolutely incapable of working out the practical points...

Though Sherlock initially tells Watson that Mycroft audits books for some government departments, he later reveals that Mycroft's true role is more substantial. While Conan Doyle's stories leave unclear what Mycroft Holmes' exact position is in the British government, Sherlock Holmes says that "Occasionally he is the British government [...] the most indispensable man in the country." He apparently serves as a sort of human computer, as stated in "The Bruce-Partington Plans":

He has the tidiest and most orderly brain, with the greatest capacity for storing facts, of any man living. The same great powers which I have turned to the detection of crime he has used for this particular business. The conclusions of every department are passed to him, and he is the central exchange, the clearinghouse, which makes out the balance. All other men are specialists, but his specialism is omniscience. We will suppose that a minister needs information as to a point which involves the Navy, India, Canada and the bimetallic question; he could get his separate advices from various departments upon each, but only Mycroft can focus them all, and say offhand how each factor would affect the other. They began by using him as a short-cut, a convenience; now he has made himself an essential. In that great brain of his everything is pigeon-holed and can be handed out in an instant.

Mycroft appears or is mentioned in four stories by Doyle: "The Greek Interpreter", "The Final Problem", "The Empty House" and "The Bruce-Partington Plans". While he does occasionally exert himself in these stories on behalf of his brother, he on the whole remains a sedentary problem-solver, providing solutions based on seemingly no evidence and trusting Sherlock to handle any of the practical details. In fact, Mycroft's own lack of practicality is a severe handicap despite his inductive talents: in "The Greek Interpreter", his blundering approach to the case nearly costs the client his life.

Mycroft resembles Sherlock, but is described in "The Greek Interpreter" as being "a much larger and stouter man". In "The Bruce-Partington Plans", the following description is given:

Heavily built and massive, there was a suggestion of uncouth physical inertia in the figure, but above this unwieldy frame there was perched a head so masterful in its brow, so alert in its steel-grey, deep-set eyes, so firm in its lips, and so subtle in its play of expression, that after the first glance one forgot the gross body and remembered only the dominant mind.

Mycroft spends most of his time at the Diogenes Club, which he co-founded.

He is the only character to refer to Sherlock exclusively by his first name.

In other mediaEdit

Mycroft Holmes has been portrayed many times in film, television, and radio adaptations of the Holmes stories.


  • Mycroft appeared In the episodes "The Bruce-Partington Plans" (November 6, 1939) and "The Greek Interpreter" (January 15, 1940) in the radio series starring Basil Rathbone as Holmes and Nigel Bruce as Dr. Watson; unfortunately, no cast listing currently exists to show who portrayed him. In the same series, "The Greek Interpreter" was adapted again on July 23, 1943 and "The Bruce-Partington Plans" on September 10, 1943; it is currently unknown whether the same scripts and same actor for Mycroft were used.
  • In the 1950s radio series starring John Gielgud as Sherlock Holmes, Gielgud's own brother, Val Gielgud, played the part in "The Bruce-Partington Plans".
  • In the BBC radio dramatisations with Carleton Hobbs and Norman Shelley, Mycroft was played at various times by Malcolm Graeme, Keith Williams, Felix Felton and – in "The Empty House" – by Carleton Hobbs himself.
  • In the BBC Radio adaptations starring Clive Merrison as Sherlock and Michael Williams as Watson, John Hartley played Mycroft in "The Greek Interpreter" on 21 October 1992, "The Bruce-Partington Plans" on 24 January 1994 and "The Retired Colourman" on 29 March 1995.

Film and televisionEdit

  • The first film appearance of Mycroft Holmes was in the 1922 film The Bruce Partington Plans, where he was played by Lewis Gilbert.
  • Mycroft was supposed to appear in the 1943 film Sherlock Holmes in Washington but was replaced by Mr. Ahrens.
  • The BBC broadcast two Sherlock Holmes series in 1965 and 1968 which starred Douglas Wilmer (1965) and Peter Cushing (1968) as Sherlock and Nigel Stock as Watson. Mycroft appeared twice, once in 1965 in The Bruce-Partington Plans and played by Derek Francis and in 1968 in The Greek Interpreter and played by Ronald Adam.
  • In the 1965 film A Study in Terror, Mycroft is played by Robert Morley.
  • In the Billy Wilder-directed film The Private Life of Sherlock Holmes (1970), which starred Robert Stephens as Sherlock, Mycroft was played by Christopher Lee (who also played Sherlock Holmes in other productions before and since). In this film, which purports to show the 'real' people behind Watson's dramatised accounts, Mycroft is nearly unrecognisable: whippet-thin and not notably indolent. He is also depicted as either the head or at least a senior operative of the British secret service, for which the Diogenes Club is a front.
  • Charles Gray assumed the character in both the 1976 film The Seven-Per-Cent Solution and four episodes of Granada Television's The Adventures of Sherlock Holmes series in the late 1980s and early 1990s. Gray's first two television appearances were adaptations of the two stories in which Mycroft actually appears (The Greek Interpreter and The Bruce-Partington Plans). In the two other appearances, the character was used to replace another for various reasons:
    • The Golden Pince-Nez – Mycroft was used in place of Watson due to Edward Hardwicke being unavailable.
    • The Mazarin Stone – Mycroft was used in place of Sherlock owing to Jeremy Brett's ill health.
  • The 1975 film The Adventure of Sherlock Holmes' Smarter Brother, starring Gene Wilder as Holmes' younger brother "Sigerson Holmes," was inspired by Mycroft, who is mentioned, but does not appear except in a photograph of the three brothers as children.
  • Boris Klyuyev played Mycroft Holmes in The Adventures of Sherlock Holmes and Dr. Watson, a Soviet TV series. Klyuyev was nine years younger than Vasily Livanov, who played Sherlock Holmes. According to Sherlock, Mycroft is married and has a son.
  • He is also briefly mentioned in the 1985 film, Young Sherlock Holmes; when Sherlock is expelled from boarding school, he tells Watson that he plans to stay at his brother Mycroft's for a few days.
  • Peter Jeffrey played Mycroft in the 1990 film Hands of a Murderer which starred Edward Woodward as Sherlock, John Hillerman as Watson and Anthony Andrews as Professor Moriarty.
  • Jerome Willis played Mycroft in Sherlock Holmes and the Leading Lady, a 1992 made-for-TV film which starred Christopher Lee as Holmes and Patrick Macnee as Watson.
  • R.H. Thomson played Mycroft in the 2001 made-for-TV film The Royal Scandal opposite Matt Frewer's Sherlock.
  • Richard E. Grant played him as a semi-crippled young man – following a bad trip after he was injected with drugs by Moriarty – in Sherlock: Case of Evil (2002).
  • In the 2010 BBC television series Sherlock, Mycroft is portrayed by series co-creator Mark Gatiss. In this contemporary version, Sherlock and Mycroft exhibit smouldering animosity towards each other (which Dr. Watson characterises as "sibling rivalry" and Mycroft himself refers to as a "childish feud"). Mycroft is part of the Cabinet Office and is so powerful that he can use mass surveillance to track Sherlock. In keeping with the books, Mycroft describes himself as "occupying a small position in the British government", but more accurately, "he is the British government". While Sherlock reveals that Mycroft essentially bullied him as a child and has made him feel stupid throughout his life, going so far as to suggest that they would both be willing to arrange the death of the other, Mycroft gradually reveals a well-hidden deep familial love for his brother, something Sherlock, in time, begins to reciprocate. In the 2015 Christmas Special "The Abominable Bride", he is portrayed by Gatiss in heavy makeup as morbidly obese, more in keeping with the original stories.
  • Stephen Fry played Mycroft in the Guy Ritchie-directed Sherlock Holmes: A Game of Shadows, released in December 2011.[1]
  • Rhys Ifans played Mycroft Holmes in another modern adaptation, Elementary.[2] In this series, Mycroft is introduced as a London restaurateur who later turns out to work for MI6 as a source due to his restaurants being used as a front for various crime organisations. Mycroft goes into hiding at the end of the second season when he exposed his ties to MI6 to help Sherlock with a case, which Holmes feels reflected a lack of trust in him to find another solution. In the sixth season episode "Nobody Lives Forever", it is revealed that Mycroft died ten months prior to the events of that episode of a brain haemorrhage, which Sherlock was never informed about until he started digging.
  • In the Russian TV adaptation from 2013, Igor Petrenko played Mycroft Holmes, as a twin brother of Sherlock, who is serving The Queen.
  • In the NHK puppetry Sherlock Holmes, Mycroft is a fat young man who is in the sixth grade of Beeton School. He is in the position of managing the pupils of Dealer house in which he lives, the head of the pupil council and member of Diogenes Club in his house. Though he has deductive powers superior to Sherlock, he is more calculating than his younger brother.
  • In the 2015 film Mr. Holmes, set in 1947, though it is revealed that Mycroft died a year or so earlier, he appears briefly, played by John Sessions.
  • In the Japanese television series, Miss Sherlock, which premiered in 2018, Yukiyoshi Ozawa plays Kento Futaba, who is modeled on Mycroft. He is the older brother of Yuko Takeuchi's Sherlock, who respects his intelligence, and he holds a prominent position in the government's Intelligence Agency.
  • Hugh Laurie played Mycroft in the 2018 film Holmes & Watson.
  • Sam Claflin is due to play Mycroft in the upcoming Enola Holmes.

Through the series, Mycroft is steadfastly determined to capture her while Sherlock gradually grows to respect her considerable talents and begins to understand her reasons for her defiance.
