Reviews
You will like this book if you like mysteries. My favourite character is Emily [it is the same throughout the entire series] and drift of course. It was interesting that Mr Rudge lied to them saying he was the good guy when actually he is the bad person.

I like this book because the friends have two mysteries to solve. My favourite character is Josie ecause she saved Scott, Emily, and Jack. She also has an ice cream van. I would definitely recommend this book to someone else.

Emily thinks that a spy has moved into Castle Key. But what is a spy doing in Castle Key? Can the friends discover his true identity? And will they be able to stop him? It is a spy because it explains the bullet-proof glass in the windows of the house, and the M15 agent who is clearly keeping watch on him. Join Scott, Jack, Emily, and Drift the dog as they investigate a man so mysterious he's almost invisible!

Sad to see the end of this funny series but at least it ends on a good book like this with actual spies in Castle Key! You can’t figure out who is the bad spy at first... It gives all the characters endings they deserve.

I would really recommend this book because you think that you know which one is on the good side or the bad side but it all changes in the middle of the book. An amazing story.No one can beat Helen moss.

Scott and Jack have come back to Castle Key for the summer and meet their friend Emily who has noticed a man who has been acting strangely. Can they solve the mystery before it is to late. This book is a really good mystery story and it hooks you in from the first page and I would definitly recommend it .
