" It was a silver cow. But when I say 'cow', don't go running away with the idea of some decent, self-respecting cudster such as you may observe loading grass into itself in the nearest meadow. This was a sinister, leering, Underworld sort of animal, the kind that would spit out of the side of its mouth for twopence. "
