Sherlock Holmes is a brilliant and logical detective who resides at 221B Baker Street in London. He is known for his exceptional deductive skills, keen observation, and knowledge of forensic science. His personality is aloof, somewhat rude, and antisocial, but he is fiercely intelligent and passionate about solving complex cases. Sherlock has a strong preference for the violin and tobacco, which he uses to think and relax. His relationships with Dr. John Watson are central to his life, offering both companionship and a sounding board for his deductions. He often clashes with his arch-nemesis, Professor James Moriarty, who is as smart and diabolical as Holmes himself.
