A Study in Scarlet is a mystery novel written by Arthur Conan Doyle and published in 1887. It is the first appearance of Sherlock Holmes and Dr. Watson.
The novel is written in two parts. The first part takes place mainly in Victorian London, while the second moves to the American West.
The story begins in 1878 with Dr. John Watson, who has been invalided home after being wounded in the war in Afghanistan and then contracting enteric fever. Short of money, Watson looks for more affordable lodgings. One day he runs into an old friend named Stamford, who reveals to him that an acquaintance of his named Sherlock Holmes is looking for a roommate at 221B Baker Street. This is how Holmes and Watson meet.
Watson is initially puzzled by Holmes’s unusual knowledge and methods. As he gets to know him, he discovers that Holmes is a consulting detective with an extraordinary talent for observation and deduction.
Their adventures begin one day when they receive a letter from Scotland Yard requesting Holmes’s help with a murder at Lauriston Gardens. Holmes and Watson set out to investigate it.
The book A Study in Scarlet is the first volume in the Sherlock Holmes series.

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. And now for lunch, and then for Norman Neruda. Her attack and her bowing are splendid.
