Judging from the patterns of texts Doyle, Sherlock Holmes was born on 15 July 1854. His father was an English squire and his mother descended from a line of French painters. Has a brother, Mycroft, thanks to the prodigious powers to manage vast amounts of information held, working almost anonymously as general coordinator and internal reports of the affairs of the British government. Sherlock Holmes seems to have been a student in college, probably at Oxford, but certainly not Cambridge. After graduation, staying near the British Museum to study science for the development of his later career. Meet Watson in 1881 at St. Bartholomew's Hospital. Refuses knighthood, but accepted the Legion of Honor. His great enemy, also of extraordinary intellectual powers, is Professor Moriarty, who apparently came to end the life of the eminent detective in the cascade of Reichenbach, Switzerland (The Adventure of the Final Problem). Doyle had to choose to resurrect his hero when thousands of readers protested wearing black ribbons on their hats as a sign of mourning. Sherlock Holmes returns in the case The empty house (The return of Sherlock Holmes, 1903). After a career of 23 years, of which Watson shared 17 with him, Holmes retired to Sussex, where he focused on beekeeping, and even wrote a book entitled Manual of beekeeping, with some observations on the separation of the queen, and also, almost incidentally, solved one of their most difficult cases: "The Adventure of the lion's mane" (1907). Following his retirement as a detective took two years to thoroughly prepare a major counterintelligence action shortly before the outbreak of the First World War. Nothing about it has since 1914.
