Thomas Herndon was happily studying economics at the University of Massachusetts, when one day is punctured by a discovery. It appears to be an anomaly which, if true, will shake the intellectual foundations of a global movement, and could undermine politicians around the world.

Hannah Fry tells the extraordinary story of a student who will go head to head with two of the greatest economic minds in modern times. But can he win?
