The plot of the movie closely follows the short story "The Final Problem", which is included in "The Memoirs of Sherlock Holmes".

Toward the beginning of the film, Watson enters Holmes' room on Baker Street that's full of eccentricities; looking out the window is a mannequin to act as Holmes' doppelganger. This idea was first used in the short story "The Empty Room" found in "The Return of Sherlock Holmes". The dummy was used again in the short story "The Mazarin Stone" found in "The Case-Book of Sherlock Holmes".

The note left by Holmes and read by Watson; "Come at once if convenient - If inconvenient come all the same." was taken directly from the short story "The Creeping Man" found in "The Case-Book of Sherlock Holmes".
