“No man burdens his mind with small matters unless he has some very good reason for doing so.” - Sherlock Holmes
Few fictional characters reach the level of fame achieved by Sir Arthur Conan Doyle's Sherlock Holmes. The character's first appearance was A Study In Scarlet, which was published in the magazine "Beetson's Christmas Annual" in 1887. Though Sherlock Holmes was not the first mystery novel hero, he is certainly the most well known, with numerous adaptations for the radio and the screen. Interesting to note, the phrase "Elementary, my dear Watson" was never actually said in any of the original Sherlock Holmes books. Holmes was known to occasionally exclaim "elementary" and would sometimes refer to Dr. Watson as "my dear Watson", so this is likely where the confusion stems from.
