Holmes is an eccentric individual with a sharp wit and a flair for the dramatic. He exhibits a profound sense of justice and an unwavering commitment to truth. Holmes is reclusive, preferring the company of his loyal friend, Dr. Watson, to that of most other people. His arch-enemy is the master criminal, Professor Moriarty, whom he greatly respects as a worthy opponent. Holmes often shows disregard for social conventions, living in an untidy apartment at 221B Baker Street, London, where he conducts his investigations.
