The Adventures and Memoirs of Sherlock Holmes is a collection of the first twenty four short stories based on the famous detective, including the cases of The Red-Headed League, The Cardboard Box, and The Final Problem. Holmes will need to use his various skills, including a knack at cracking ciphers, an aptitude for acting and disguise, tracking footprints, hand to hand combat, deciphering different types of tobacco ash, and knowledge of psychology to solve cases of blackmail, revenge and murder. 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.
