When I picked up this story by Lee Child, the last thing I expected was math. At least I didn’t have to solve any equations!
Nathan is a mathematician and a university professor. He’s well known in his field, but mathematicians aren’t quite celebrity material. So needless to say he’s tremendously surprised when he gets a call from the White House, telling him that his help is needed.
“He was a very able mathematician. But there were fifty others in the world just as good. Maybe a hundred. His publication history was competitive. He had contributed to all the important journals. But so had fifty others. Maybe a hundred. His debut had been his PhD thesis. Groundbreaking, really, but in a field no one was interested in. Nothing about him stood out.”
He is flown to a meeting at the National Security Agency—a meeting attended by a famous mathematician and the President of the United States, as well as two intelligence officers. When Nathan is shown a series of 11 equations, he determines that they are part of a computer security algorithm. The correct numerical sequence is a powerful tool: it controls access to Russia’s nuclear arsenal.
The person who created the algorithm is a famed Russian mathematician. The President and his security team want Nathan to meet this man to try and get feel for which of the 11 equations will allow them the access they need. So they get Nathan an invitation to attend a mathematics conference in Russia, and he should be able to meet the man. But nothing goes quite like expected.
This was very different than anything else of Lee Child’s that I’ve read. There were more twists than I was expecting, but it was a little dry. Or maybe it’s my phobia about math…
