A Study in Scarlet by Sir Arthur Conan Doyle is the novel that initiated the unique relationship between John Watson, a doctor, and Sherlock Holmes, who was a scholar, a scientist, and a brilliant but unofficial detective.
Not long after meeting each other and mutually agreeing to be each other’s roommate in the famous 221b Baker Street flat, Dr. Watson and Holmes are asked by Scotland Yard to help solve a puzzling murder. As the detective’s intrinsic skill of deductive reasoning begins to work on overlooked clues and on ignored suspects, the reader and the narrator, Dr. Watson, are caught up in the tragic and, at times, romantic story that unfolds with the mystery.
This first novel by Sir Doyle is frequently overlooked by first-time readers of his famous detective series, although A Study in Scarlet is the crucial introduction and key to the sequent stories and novels about Sherlock Holmes.
