I pressed my hand on her shoulder, just a little, so as she couldn’t pretend not to know it was there. But she didn’t seem to notice.

‘Ah, well,’ I said, ‘I suppose I’ll be on the wallaby again next week.’

‘Will you, Mr Wilson?’ she said. Her voice seemed very soft.

I slipped my arm round her waist, under her arm. My heart was going like clockwork now.

Presently she said—

‘Don’t you think it’s time to go back now, Mr Wilson?’

‘Oh, there’s plenty of time!’ I said. I shifted up, and put my arm farther round, and held her closer. She sat straight up, looking right in front of her, but she began to breathe hard.

‘Mary,’ I said.

‘Yes,’ she said.

‘Call me Joe,’ I said.
