This was my favorite of the Adrien English books, but I'm not sure I could articulate why. The combination of a mystery that was engaging and difficult to pin down, emotional turmoil in Adrien's life, and tension with the reintroduction of Jake all combined to make a great story that I didn't want to end. Speaking of the ending, I thought this book did a great job of keeping the tension going. Even though I was more sure of the outcome than Adrien himself was, I definitely believed that he thought it was all going to end horribly. 
 I'm so glad that the hero of this series runs against archetypal detective norms. Adrien is so wonderful to read, and I can't wait for more of his stories!
