Number One**********************

The puzzles in this book are very interesting, just like playing a game, requiring constant thinking and reasoning. Moreover, the stories in the book are very graphic, and I feel like a detective. I think this book is very suitable for people who like reasoning. Just like "Sherlock Holmes", it can make people immersed in the case. Moreover, I think the author is very good at coming up with so many interesting puzzles. By the way, the police chief in the book also left a deep impression on me. He was very calm and very observant. I think I should also learn from him and not panic when things happen.
