Sherlock Holmes is a fictional consulting detective created by Sir Arthur Conan Doyle. He is known for his extraordinary powers of deduction, observational skills, and logical reasoning. Holmes prefers the company of his intellectual equal, his loyal friend and chronicler Dr. Watson, over most others, and has a keen dislike for emotional displays and bureaucracy. He is often perceived as aloof and arrogant, but his loyalty to justice and pursuit of truth are paramount. Holmes often clashes with his nemesis, the master criminal Professor Moriarty. Holmes inhabits the world of Victorian London, where his adventures take him through the city's foggy streets and into the darker corners of society.
