The book “The Best Detective” is an easy mystery book. In the book, Nancy loses her detective notebook, and inside the notebook, there are 3 movie tickets that she needs to watch with her 2 best friends. However that is not the worse, the worse is Jason try to find her notebook, to prove that he is the best detective. At the end, Nancy finds that. I think this book is good, although is an easy book to read, but the mystery in this book you can always meet it in your life. For example, I am a person who always lost things. This book tells you be careful your own thing, that's your responsibility.
