Rollie and his friend, Cecily, are presented with another mystery, a secret map hidden in a newspaper and a spy lurking within the Academy. There are many clues and mysterious things happening, but which details are actually pointing to the spy and which are the red herrings?

I loved everything about this book! The characters, the plot, the mystery, the action, the school, the writing style... everything is wonderful!

Rollie is an excellent main character. He's smart and observant, and he wants to be just like Sherlock Holmes. I really identified with his thought process and his emotions and excitement in the middle of a mystery.

I loved the easy friendship between Rollie and Cecily. They are great friends, and it really shows in their banter and camaraderie. I loved how they nickname each other "Holmes" and "Watson." Their friendship is even further cemented in this second book in the series.

It was really interesting to see how Rollie begins to connect with more of the side characters in this book. He has a misunderstanding with one of his roommates, Rupert, and is convinced that because Rupert is a nasty rude person, he must be working as a spy for the bad guys. Rollie learns not to let his personal feelings get in the way of finding actual evidence. This was such a great exploration of different types of relationships and how we can easily misjudge people.

The writing style is excellent, drawing the reader into the story. The plot leaves little foreshadowing clues all over the place for the reader to wonder over until the mystery is revealed. I love the puzzles and codes, and the plot kept me interested right to the very end.

I can't wait to read more books in this series!
