It has been estimated that Sherlock Holmes is the most prolific screen character in the history of cinema.

The first episode, "The Case of the Cunningham Heritage," adapts the first section of "A Study in Scarlet", in which Holmes and Watson's relationship is established, and develops an original story from there.
