The Sign of Four

The character of Sherlock Holmes, created by Sir Arthur Conan Doyle, revolutionized crime fiction with his keen observation and logical reasoning. Starting with "A Study in Scarlet" in 1887, Doyle penned four novels and over fifty short stories featuring Holmes and his companion, Dr. Watson. These works not only established a new genre but also set enduring standards for detective narratives, making Holmes an iconic figure in literature.
