A Study in Scarlet

A Study in Scarlet is an 1887 detective novel by British writer Arthur Conan Doyle. The story marks the first appearance of Sherlock Holmes and Dr. Watson, who would become the most famous detective duo in literature. The book's title derives from a speech given by Holmes, a consulting detective, to his friend and chronicler Watson on the nature of his work, in which he describes the story's murder investigation as his "study in scarlet": "There's the scarlet thread of murder running through the colourless skein of life, and our duty is to unravel it, and isolate it, and expose every inch of it." The story, and its main characters, attracted little public interest when it first appeared. Only eleven complete copies of the magazine in which the story first appeared, Beeton's Christmas Annual for 1887, are known to exist now, which have considerable value. Although Conan Doyle wrote 56 short stories featuring Holmes, A Study in Scarlet is one of only four full-length novels in the original canon. The novel was followed by The Sign of the Four, published in 1890. A Study in Scarlet was the first work of detective fiction to incorporate the magnifying glass as an investigative tool. Plot Part I: The Reminiscences of Watson In 1881, Doctor John Watson returns to London after serving in the Second Anglo-Afghan War and starts looking for a place to live. An old friend tells him that Sherlock Holmes is looking for someone to split the rent at a flat at 221B Baker Street but cautions Watson about Holmes's eccentricities. Holmes and Watson meet and, after assessing each other and the rooms, they move in. Holmes is a "consulting detective", and his frequent guests are clients. After a demonstration of Holmes's deductive skills, Watson's disbelief turns into astonishment.
