Sherlock Holmes by Sir Arthur Conan DoyleFirst of all, Holmes is the first scientific detective. Second, all of his cases have been solved, so there are no flaws in his method. Well, after researching books and websites, I finally found the "real" way Holmes solved crimes. The site where I found such spectacular information is Sherlockian.Net. This view was helpful and made me understand most of Conan Doyle's stories. The way Holmes began most investigations was to find an alternative and guard against it. This step is comparable to the popular saying “don’t put all your eggs in one basket.” Holmes never had a single thought about what had happened. What made Sherlock great was that all the possibilities were relevant to him. Nothing could ever escape him. If something extraordinary happened, it wouldn't be a surprise to him. Next comes the data research stage. Holmes once said: “It is a capital error to theorize without data. » You should never propose theories and then try to support them. You always have to find facts and then come up with theories. I think you're going in the wrong direction if you do it backwards. Not only will the crime take longer to solve, but it can never be solved. Once Holmes had all his data and theories in order, he determined what he had, what he needed, where he needed to be. This is all based on self-experience. It is detectives who carry out this task, not just ordinary civilians. For an example in The Adventure of the Speckled Band, Holmes connected the crime to being bedridden under an unnecessary fan. There's no way everyone can do this easily. I'm trying to say that Holmes was a born detective, even a great one. That pretty much sums up all his work. We can forget the golden rule. This rule is to never guess. Guessing only keeps you attached. You need hard facts, solid theories, and all that other good stuff to solve a crime. Guessing is the number one sin in solving a crime. Finally, I think Holmes approached all his crimes fictionally..
