Andrew O’Hagan’s sensational state-of-the-nation novel Caledonian Road begins with the protagonist Campbell Flynn – art critic, academic, ‘podcast warrior’ – gliding through the streets of London in the back of a glass-ceilinged black cab. Entirely dry-eyed himself, Flynn is off to meet his literary agent for lunch in the Wolseley to discuss his new book Why Men Weep in Their Cars: The Crisis of Male Identity in the Twenty-First Century.
