"The Adventures of Sherlock Holmes" is a collection of twelve short stories by Arthur Conan Doyle, first published on 14 October 1892. It contains the earliest short stories featuring the consulting detective Sherlock Holmes, which had been published in twelve monthly issues of "The Strand Magazine" from July 1891 to June 1892. The only characters common to all twelve are Holmes and Dr. Watson and all are related in first-person narrative from Watson's point of view.
In general the stories in "The Adventures of Sherlock Holmes" identify, and try to correct, social injustices. Holmes is portrayed as offering a new, fairer sense of justice. The stories were well received, and boosted the subscriptions figures of "The Strand Magazine", prompting Doyle to be able to demand more money for his next set of stories.
