Having watched the movie a few weeks ago, I was curious about the book. The movie is substantially, sometimes comically hollywoodized, which I had expected, given it’s sort of Robert Langdon-esk style.

The book turns out to be, as with the movie, just alright, for me. I find the author lingers on stuff I don’t care about and substantially abstracts aspects of crime thrillers that I go to them for. But I do find the maths concept pretty interesting, and it is better in the book. Less dumbed down for the audience and just much better articulated.

It’s also got a memoir type feel, probably trying to evoke some Watson-Holmes, where he is looking back on his life. This deflated the stakes and, along with the abstraction, makes it very hard to care about the characters. It’s a decent story, though.
