'I can't let you eat any more of that,' I said. 'It's not good for you.'

And having got hold of his hand I kept it.

There now, I said, holding it tight.

He looked up at me vaguely, absorbed in his thoughts; then, realising how tight his hand was being held, he smiled.

'You dear child,' he said, scanning my face as though he had never seen it before.

'Yes?' I said, smiling in my turn and not letting go of his hand. 'I like that. I didn't like any of the other dear children I was.'

'Which other dear children?'

'Uncle Rudolph,' I said, 'let's go home. This is a bleak place. Why do we sit here shivering forlornly when there's all that waiting for us down there?'

And loosing his hand I got on to my feet, and when I was on them I held out both my hands to him and pulled him up, and he standing lower than where I was our eyes were then on a level.

'All what?' he asked, his eyes searching mine.
