The novel begins in the famous apartment 221B Baker Street, home to Sherlock Holmes who is visited by clients in need of assistance in resolving various issues. Unsurprisingly, Sherlock Holmes works his magic in order to find a logical solution to each mystery. Narrated through the perspective of Dr. Watson, Holmes's close friend and companion, he serves as a monitor as he accompanies or is given a full account of the sequence of events surrounding investigation details. Watson then documents each adventure and shares it with the readers which in turn act as memoirs of Holmes's achievements. This type of narration only enhances the sense of mystery surrounding each case because of the occasional missing detail and leaves the reader wondering about the next course of action. Interestingly, Holmes offers logical explanations for each of his solutions, but nevertheless manages to keep the audience on their toes.
