Did Sherlock Holmes go to America?

Answer 1

Not in the books, however, Sir Arthur Conan Doyle did.

'A Study in Scarlet,' 'The Adventure of the Noble Bachelor,' 'The Adventure of the Yellow Face,' 'The Hound of the Baskervilles,' 'The Adventure of the Dancing Men,' 'The Adventure of Wisteria Lodge,' 'The Valley of Fear,' 'The Problem of Thor Bridge,' 'The Adventure of the Three Garridebs' and possibly others contain characters from America, but the representation is often inaccurate.
