This book was really interesting and well-written!!!! I especially appreciated all the advanced words(on my level, of course)and how the characters very openly expressed sheer and non-sheer emotion, oh, and of course, how cool this book is.

I like mystery so this was a must read for me.

It was a good book. I love mysteries. My favorite part was when the boys thought that an old man was a spy.

I liked this book , it was fun to read

Book was good
