Sherlock Holmes

I think in the book Sherlock Holmes, Sherlock Holmes presents cleverness and intelligence by known where people have been or done just by what they wear or use. " Now, you will observe that he could not have been on the sttaf of the hosipital, since only a man well-established in a London practice could hold such a position, and such a one would not drift into the country." He knows that the masn has worked in the country and a little about his life. I think that shows his personality and adds to the story.
