Sherlock Holmes is a character created by British writer Arthur Conan Doyle in 1887 for 4 novels and 56 short stories that appeared in the monthly magazine The Strand Magazine. He is a private detective and police consultant, with extraordinary deductive ability, practical knowledge of chemistry, anatomy, geology, astronomy, boxing, fencing, law, acting, theatrical makeup, music (he is a violinist), police literature, . . . but his main ability to solve cases is in observation and analysis. He had enormous popularity in his time (England of the late nineteenth century, early twentieth century) almost at the height of today's superheroes, with a companion of adventures such as Dr. John H. Watson (his friend and chief chronicler), an archenemy like math professor James Moriarty, a worthy and beautiful opponent like Irene Adler (I can think of, like Batman's Catwoman), a drug addiction (like Ironman?) , and even died and rose again (as Superman! 128513; ) , although the latter at the request of the public; to top it off, and like other fictional characters, he also participated in a world war (the first) in counter-espionage duties for the United Kingdom against Germany. His fame extends to today, with movies, series, comics, manga and plays with him as the protagonist or with his inspiration.
