The Final Problem
Doyle determined that these would be the last Holmes stories, and intended to kill off the character in "The Final Problem". Reader demand stimulated him to write another Holmes novel in 1901–1902, "The Hound of the Baskervilles", set before "The Final Problem". Next year a new series, "The Return of Sherlock Holmes", begins with the aftermath of "The Final Problem", in which it is revealed that Holmes actually survived.
