Simon Fanshawe finds out how the nation's question setters manage to keep up with the insatiable demand for quizzes on radio, television, and pubs.
Every day, millions of people try to get the better of the question setters: radio listeners, TV viewers, pub know-alls.

Simon journeys from the seclusion of a terraced house in Liverpool to the pressures of the British Quizzing Championship to delve into the dark art of the question setter.
