Sherlock Holmes is the most famous detective and most portrayed literary character in film and TV. Created by Sir Arthur Conan Doyle, Sherlock first appeared in print in 1887 with A Study in Scarlet.

Doyle is a British author who wrote across multiple genres. However, he is best known for his stories on legendary private detective Sherlock Holmes. Most of the stories take place during the Victorian or Edwardian era and are narrated by Holmes’ sidekick and best friend — Dr. Watson.

The world’s first and only “consulting detective” was inspired by the real-life figure of Joseph Bell — a surgeon for whom the author had worked for as a clerk.

Sherlock is a mastermind and he loves solving mysteries. His reasoning, eye for detail and power of deduction make for suspenseful and captivating plots. The friendship between the famous detective and Dr. Watson is one of the literature’s greatest. The constant bickering and banter between the two brings delicious and unexpected humor.

Sherlock is a brilliant man with a strong penchant for challenging cases. While he’s usually brutally honest and quite cold, the detective can sometimes become very emotional in a righteous cause.
