A Study in Scarlet

First published in 1887, A Study in Scarlet is the first crime that Sherlock Holmes solves with his companion Doctor Watson. A murder that leaves the Police clueless is brilliantly solved by the master detectives - Holmes and Watson. The book's title is derived from a speech that Holmes gives to his companion Doctor 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.""
