"A slap on the hand or a box on the ear was no good: what he wanted was to get a nice warm whipping. I was surprised at this sentiment and involuntarily glanced up at his face. As I did so I met the gaze of a pair of bottle-green eyes peering at me from under a twitching forehead. I turned my eyes away again."
