Passage: Conan Doyle's 56 short stories and four novels are known as the "canon" by Holmes aficionados. Early canonical scholars included Ronald Knox in Britain and Christopher Morley in New York. Morley founded The Baker Street Irregulars—the first society devoted to the Holmes canon—in 1934.The Sherlockian game (also known as the Holmesian game, the Great Game, or simply the Game) attempts to resolve anomalies and clarify details about Holmes and Watson from the canon. The Game, which treats Holmes and Watson as real people (and Conan Doyle as Watson's literary agent), combines history with aspects of the stories to construct biographies and other scholarly analyses of these aspects. Ronald Knox is credited with inventing the Game.One detail analyzed in the Game is Holmes's birth date. The chronology of the stories is notoriously difficult, with many stories lacking dates and many others containing contradictory ones. Morley and William Baring-Gould (author of Sherlock Holmes of Baker Street: A Life of the World's First Consulting Detective) contend that the detective was born on 6 January 1854, the year being derived from the statement in "His Last Bow" that he was 60 years of age in 1914, while the precise day is derived from broader, non-canonical speculation. This is the date the Baker Street Irregulars work from, with their annual dinner being held each January. Laurie R. King also speculated about Holmes's birth date. She instead argues that details in "The Adventure of the Gloria Scott" (a story with no precise internal date) indicate that Holmes finished his second (and final) year of university in 1880 or 1885. If he began university at age 17, his birth year could be as late as 1868.Holmes's emotional and mental health have long been subjects of analysis in the Game. At their first meeting, in A Study in Scarlet, the detective warns Watson that he gets "in the dumps at times" and doesn't open his "mouth for days on end". Leslie S. Klinger has suggested that Holmes exhibits signs of bipolar disorder, with...
