Sherlock Holmes is a fictional consulting detective created by Sir Arthur Conan Doyle. Holmes is known for his expertise in deduction, rational thought, and forensic science. His primary trait is his razor-sharp intellect, often solving crimes that baffle even the most seasoned detectives. Holmes is reclusive, preferring solitude and the companionship of his friend, Dr. Watson, over others. He is also meticulous in his methods, with a preference for violin music and chemical experiments in his leisure time. His complex personality ranges from aloof to fiercely logical. Holmes often clashes with his arch-nemesis, Professor Moriarty, and displays a cold indifference to the comfort of others, though he harbors a profound concern for justice and truth.
