Sir Arthur Conan Doyle created the world's most famous detective when he introduced Sherlock Holmes in 1887, and in doing so, he invented the modern mystery genre as we know it. The brilliant, eccentric detective with his unmatched powers of observation and deduction, paired with the steadfast Dr. Watson, became an instant phenomenon that has never faded. Conan Doyle's stories are masterclasses in plotting and atmosphere, combining clever puzzles with the foggy intrigue of Victorian London. Holmes has transcended literature to become a cultural icon, adapted endlessly across every medium, yet readers still return to the original tales for their wit, ingenuity, and sheer entertainment value. These stories prove that popular fiction can be both wildly entertaining and genuinely brilliant, creating a character so vivid that many people refuse to believe he wasn't real.
