The Memoirs of Sherlock Holmes is a collection of short stories, including the adventures of The Silver Blaze, The Musgrave Ritual, and The Final Problem. This collection not only introduces the term "smoking gun", it also introduces Holmes' greatest nemesis, Professor Moriarty. Holmes will need to use his various skills, including a knack at cracking ciphers, deciphering riddles, tricking thieves, analyzing tracks, and faking sickness to solve cases involving impersonation, burglary and revenge. Sherlock Holmes is famous for his intellectual prowess and is renowned for his skilful use of deductive reasoning, astute observation, and forensic skills to solve difficult cases. Deductive reasoning allows Holmes to impressively reveal a stranger's occupation. Similarly, by studying inanimate objects, he is able to make astonishingly detailed deductions about their owners. This mindset was a major innovation in the field of crime fiction, inspiring authors like Robert J. Sawyer, Neil Gaiman and Stephen King.
