As the blurb says---the story starts out with medical students finding a message hidden in a tooth in a subject in their anatomy class. What is written in that message sets into motion a series of surprising twists that add up to a very entertaining mystery. Nico and his team run all over Paris unraveling a very complex plot as the body count mounts.
I particularly enjoy the detail that Molay puts into this work. Detailed backgrounds of the various locations and a real sense of place make Paris come alive and provide fascinating bits of trivia and history. I love it when authors go the extra mile like this.
My only complaint and why this book went from 5 stars down to 4 is that I didn’t like the way the story was wrapped up. I don’t know how to go into any more detail without spoiling the story so I just won’t.
I also have to mention that if you are contemplating donating your body to science upon your death---you may reconsider after reading Crossing the Line. Creepy doesn’t even begin to describe it.
