What is the author's style in The Adventures of Sherlock Holmes by Arthur Conan Doyle?

As Watson narrates the stories here, it should be no surprise that the language that he uses is common Victorian English. Both Watson and Holmes use a somewhat refined, though not austere, English style that shows intelligence and some class status, but is not affected or silly. Much of the vocabulary that is used is probably very different and more intricate than we would find today, though that was common in Victorian England.
