In Arthur Conan Doyle's novels, Sherlock Holmes claims to be the consultant of a famous detective, which means that any problem that the police or detective can't solve will come to Sherlock Holmes.
Sherlock Holmes can often solve many important cases by sitting at home, but most of Arthur Conan Doyle's novels will encounter some cases that even Sherlock Holmes can't solve by sitting at home, which requires Holmes to go out and find out for himself. Sherlock Holmes is very good at solving crimes through small details of the crime scene and reasoning about some details.
Extended data:
Conan Doyle wrote 60 stories about Sherlock Holmes, which are familiar to many people. But in essence, Holmes is a first-class chemist. Almost every story will mention some chemicals, such as sulfuric acid, copper salt solution and so on. Of course, the story also involves toxicity testing.
The narrator Watson made it very clear about Holmes' love for chemistry. When Holmes was a student, he used the Christmas holiday to study organic chemistry experiments. Holmes has a chemistry experiment table in his apartment in Baker Street. At least once, the smell smoked Watson out of the house.
On another occasion, Holmes suspended the investigation because he wanted to complete a chemical analysis that interested him. Shylock could have solved more cases by chemical methods, but in almost all 60 stories, being a chemist made him feel great pleasure.
