I shall always be grateful to A Cab at the Door. I read most of it one Sunday evening in a Victoria line tube train which was stuck for two hours outside King’s Cross station. The train lights dimmed and instead of the Blitz spirit a sullen, twitchy silence set in. I was spectacularly lucky in my companion. The sheer vigour of V. S. Pritchett’s writing and his benign, shrewd storyteller’s voice kept me suspended in his Edwardian boyhood until ‘the juice’, as the panic-stricken driver called it, came back on and we trundled away at last.
