Charlie Higson and Ben McIntyre talk about the facts and fictions of working in espionage. Having both encountered the recruitment process for the British Intelligence Services, they discuss the process of getting recruited or, as in both of their cases, not getting recruited. They go on to explore the history and traditions of this institution, which holds the position of a household name despite being an enigma to all those outside it.This episode was recorded at the Chalke Valley History Festival 2017.
