After reading this book, I admire Holmes very much. Because of his strong observation and reasoning ability, he can infer that the other person often rides a bicycle from the edge of his shoes, and that the other person is a musician from one hand and one expression. A case that the police can't solve in three months can be solved by Holmes in a week! In Signs of Four, it seems that there are four murderers in the story, and it is not until the end of the story that you suddenly realize that there is only one criminal. Sherlock Holmes and Watson led us to solve one mystery after another. Just like idioms solitaire, you can never tell with confidence who the murderer is until the mystery is solved. With the continuous connection of the interface of idioms, my heart is constantly tense, and one wonderful story after another deeply attracts me. Even when I travel, I always take my book with me.
After reading the story, I also learned the good habit of being careful, careful and cautious from Holmes. It also greatly improved my observation. I like this book very much.
