An interesting mystery with a classic twist, a pinch of mathematics and a first person POV that is quite engaging. The murder mystery deeply set in the mathematic world is intriguing even for people who don't know anything about logics and series and theorems. The math angle is not a turn off and doesn't obliterate all of the narrative. Just enough to peak your curiosity if you are so incline. I am definitely gonna hunt down the Buzzati's story from chapter 8. The plot : a serial killer announces his crimes to a world renown mathematician and plays a game of cat and mouse with the professor and a foreign student who narrates the story. It's a good story and an enjoyable read. Yes, I had to go look for the solution for the logical series on the Net. : )
