Reichenbach Falls
Public pressure forced Conan Doyle to bring the sleuth back to life, and explain his apparently miraculous survival after his deadly struggle with Professor Moriarty in "The Final Problem". This is the first Holmes story set after his supposed death at the Reichenbach Falls, as recounted in "The Final Problem." "The Hound of the Baskervilles" had seen the return of a pre-Reichenbach Falls Sherlock Holmes, which only served to whet readers' appetites.
