In a late story by J.B. Priestley, 'Underground', an adulterer bent on escape to voluptuous Brazil boards the Northern Line. At Hampstead everyone else exits; but at the next station, a Golders Green of the imagination, dead souls crowd in and the train trundles him away to the underworld. In A Word Child, surely the best of Iris Murdoch's non-magical novels, a civil servant racked with remorse cruises for solace round and round the Circle Line, stopping only for refreshment at the platform bars of Sloane Square and Liverpool Street - both, alas, now no more.
