If, for instance, they have heard something from the postman, they attribute it to a semi-official statement; if they have fallen into conversation with a stranger at a bar, they can conscientiously describe him as a source that has hitherto proved unimpeachable. It is only when the journalist is reporting a whim of his own, and one to which he attaches minor importance, that he defines it as the opinion of well-informed circles.
Evelyn Waugh
