Sir Arthur Conan Doyle was a famous mystery writer from the 19th century. He was most famous for his creation of the all time popular Sherlock Holmes, but also did many other stories. Short stories often conclude decisively at the end and have only a few characters, characteristics and descriptions are kept simple e.g. in the “Adventure of the Engineers Thumb” “the fat man”. This description is short and concise as details of characters are minimalistic. Mystery stories often have a detective who solves the crime before the police, much like Holmes does. However in mystery stories the criminal is brought to justice, but Holmes being so unorthodox says is “commuting a felony” as he exchanged one crime for another as punishing criminals is not as important to h due to his impunities. This is due to the pleasure brought to him by solving mysteries and not bothered about crime or the police.
