it's the first Sherlock Holmes story where Watson meets Holmes.
Sherlock Holmes
Robert Downey jr has been in two Sherlock Holmes movies: Sherlock Holmes (2009) and Sherlock Holmes: A Game of Shadows (2011)
It was Doctor Watson that assisted Sherlock Holmes. He is also his flatmate. He is the first person narrator of all but four stories in the Sherlock Holmes canon.
Obviously, it has to do with what was left from the first movie. Mostly, it means Professor James Moriarty will have a bigger part to play.
A Study in Scarlet is the first one followed by: The Sign of Four The Adventures of Sherlock Holmes The Memoirs of Sherlock Holmes The Hound of the Baskervilles The Return of Sherlock Holmes The Valley of Fear His Last Bow The Casebook of Sherlock Holmes
