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.
First published in Strand magazine 1887, accumulated to four novels and fifty-six short stories set ~1880-1914.

All but four stories are narrated by Holmes's friend and biographer, Dr John H. Watson; two are narrated by Holmes himself ("The Blanched Soldier" and "The Lion's Mane") and two others are written in the third person ("The Mazarin Stone" and "His Last Bow"). In two stories ("The Musgrave Ritual" and "The Gloria Scott"), Holmes tells Watson the main story from his memories, while Watson becomes the narrator of the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, each include long omniscient narration of events unknown to Holmes or Watson.
