With the words “Elementary, my dear Watson...” the most famous detective of all times, Sherlock Holmes, starts to explain something to his friend, Dr. Watson. That phrase has now entered the English language
Sherlock Holmes first appeared in 1882. He became famous in ‘The Adventures of Sherlock Holmes”. After that came the whole series of books about him: “The Memoirs of Sherlock Holmes”, “The Return of Sherlock Holmes”, “The Hound of the Baskervilles” and many others. Many thousands of books about Sherlock Holmes are still sold every year.
Who invented Sherlock Holmes? Arthur Conan Doyle was his inventor. He was a doctor. In 1882 he moved from Scotland to England to set up a practice. One of the doctors he worked for, Dr. Joseph Bell, was the model for Sherlock Holmes's friend, Dr. Watson. Conan Doyle's medical knowledge was a great help to him in his detective stories.
Conan Doyle started the fashion of tile detective story. Today the fashion goes on.
And what sort of man is Sherlock Holmes? We learn a lot about him from the stories in which he appears. He is a quiet man, who only speaks when he has something to say. He smokes a pipe (he has a collection of them). He plays the violin. He carries a large magnifying glass. He lives at 221B Baker Street in London.
If you go to London, you will not be able to find 221 B Baker Street. But instead, you can go to a pub called the “Sherlock Holmes”. In that pub there is a room exactly like Sherlock Holmes's room at 221B Baker Street as described in Conan Doyle’s stories. On the walls there are drawings from the original editions about Sherlock Holmes.
