I enjoyed listening to this book and thought the narrator did a good job overall. The story this follows is very interesting and I enjoyed how the events and hard facts were expanded upon to create a more detailed story and better flow and atmosphere. I think that was a good choice here even though this book is nonfiction and may come across to some as reducing credibility.

I can tell the author did a lot of research and interviews to write this book, and I wish it was longer. The pacing felt too fast at times, and I have to wonder how much of Finkel's interview and research time went underutilized. If this report was already slightly dramatized to give a more novelistic approach, I wish it had been taken further to give us more depth on the tension during the crimes, or the relationship between Stéphane and Anne-Catherine (arguably one of the most compelling plot threads). 

Don't get me wrong, I really liked this book and got through it quickly. I just wish there had been more.
