In 1903, Doyle published his first Holmes short story in ten years, "The Adventure of the Empty House", in which it was explained that only Moriarty had fallen, but since Holmes had other dangerous enemies—especially Colonel Sebastian Moran—he had arranged to make it look as if he too were dead. Holmes was ultimately featured in a total of 56 short stories—the last published in 1927—and four novels by Doyle, and has since appeared in many novels and stories by other authors.
