"The Memoirs of Sherlock Holmes" are overshadowed by the event with which they close - the meeting of the great detective and Moriarty, the Napoleon of Crime. Their struggle, seemingly to the death, was to leave many readers desolate at the loss of H olmes, but was also to lead to his immortality as a literary figure. However illogical as a detective story, "The Final Problem" has proved itself an unforgettable tale. The stories that precede it included two narratives from Holmes himself, on a mu tiny at sea and a treasure hunt in a Sussex country house, as well as a meeting with his brilliant brother Mycroft.
