Sherlock Holmes is a fictional consulting detective in London 1880-1914 created by Scottish author and physician Sir Arthur Conan Doyle. Holmes, master of disguise, reasoned logically to deduce clients' background from their first appearance. He used fingerprints, chemical analysis, and forensic science. This volume contains the final set of twelve Sherlock Holmes short stories written by Arthur Conan Doyle. The stories are not in chronological order, and the only characters common to all twelve are Holmes and Dr. Watson. The stories 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.
