Who was the author of the original Sherlock Holmes stories?

Arthur Conan Doyle is well-known for creating the iconic character Sherlock Holmes. The original stories, which include "A Study in Scarlet" and "The Sign of the Four," were published in the late 19th and early 20th centuries. Doyle's writing established many conventions of the detective genre, focusing on logical reasoning and deductive skills. Holmes, alongside his companion Dr. John Watson, became synonymous with detective fiction, leading to countless adaptations and imitations.

Edgar Allan Poe is famous for his early contributions to the genre, particularly with the character C. Auguste Dupin. J.K. Rowling is best known for the Harry Potter series and is not associated with detective fiction. Thus, the choice of Arthur Conan Doyle stands out as the author behind the beloved detective stories of Sherlock Holmes.
