The novel is notable for introducing the character of Mary Morstan, Dr. Watson's future wife.

First editions of 'The Sign of Four' can be determined by their publication details—published by Spencer Blackett, featuring a cover with a street scene and the text 'New Edition' typically indicates a later printing rather than a true first edition.
