In the BBC Sherlock episodes, “The Blind Banker”, “The Great Game” and “A Scandal in Belgravia”, the writers changed some of the source material from “The Dancing” by Sir Arthur Conan Doyle Men”, “The Bruce-Partington Plans” and “A Scandal in Bohemia”, in order to modernize some of the central themes of the stories. Sherlock's writers preserved material that would continue to resonate with modern viewers of the show with the same passion with which Doyle intended his novels to resonate with his Victorian audience. The changes made bring out other themes more pertinent to modern society, while keeping most of Doyle's original messages intact. Of course there are some differences that will be present in these works due to the decision of the television series writers to bring Sherlock into the modern era in terms of setting. These differences and the changes made to the existing source material are not intended to take away from Doyle's work, but to add to it and encourage audiences to connect with the works' characters and adventures. "The Blind Banker" of the television series draws its source material from "The Dancing Men". The changes made to “The Dancing Men” are quite significant for its transformation into “The Blind Banker”. The first major change in the episode is that John Watson recently returned from active duty in Afghanistan due to injury. The series chooses to show John's problems adjusting to civilian life in the first two minutes of the episode. This characterizes Doctor Watson as needing Sherlock's constant adventures and adrenaline rushes to survive a normal life in London, further solidifying the bond between the two men. Doyle's Watson has... half the paper... "The Great Game". The fifth major change is the increased role of Mycroft Holmes in the modern version. Mycroft had a small role in Doyle's source material because he doesn't like leg work. In the modernized version Mycroft is constantly involved in the case of the missing plans and haunts Sherlock endlessly. This was changed to reflect the antagonistic relationship that can develop between siblings and make Sherlock more relatable to viewers with siblings who argue with their siblings like that. Doyle's ideas about family relationships did not include this level of arguing, especially not in public. Mycroft in the modern era is used to bring out Sherlock's childish side and push him into cases. The sheer amount of changes made to "The Bruce-Partington Plans" leaves one wondering if there are any similarities between the source and the adaptation.
