A Study in Scarlet(1914)

A Study in Scarlet is the first Sherlock Holmes mystery by Sir Arthur Conan Doyle. When Scotland Yard detective Gregson seeks help solving a baffling murder, Holmes and his companion Dr. Watson take the case. Through meticulous observation and brilliant deduction, Holmes identifies the killer as Jefferson Hope, a cab driver with a dark past. Hope confesses and reveals a tale of vengeance—years of wrongs committed by the victim that drove him to murder. Before trial, the prisoner dies of heart failure, denying justice its formal conclusion. Yet Holmes has triumphed where Scotland Yard's finest nearly convicted an innocent man, proving once again the power of his extraordinary analytical mind.
