Sir Arthur Conan Doyle (1859–1930) was a Scottish author and physician best known for creating Sherlock Holmes, one of literature’s most iconic detectives. Holmes, with his remarkable powers of observation and deduction, has become a symbol of logical reasoning. Doyle wrote four novels and 56 short stories featuring Holmes and his loyal friend, Dr. Watson. Beyond the Holmes series, Doyle was a versatile writer, producing works in historical fiction, science fiction, and supernatural tales. Despite his literary success, Doyle considered his historical novels, such as The White Company, to be his finest work. He was also deeply interested in spiritualism and wrote extensively on the subject in his later years.
