'Look here,' said George, 'this piece is going to be recast. We're going to exchange parts. You're rescuing me. See? Never mind why. I haven't time to explain it to you now. Do you understand?'

'No,' said Mr Mifflin.

'I'll get behind you and push you; but don't forget, when we get to the shore, that you've done the rescuing.'

Mr Mifflin pondered.

'Is this wise?' he said. 'It is a strong part, the rescuer, but I'm not sure the other wouldn't suit my style better. The silent hand-grip, the catch in the voice. You want a practised actor for that. I don't think you'd be up to it, George.'

'Never mind about me. That's how it's going to be.'

Mr Mifflin pondered once more.

'No,' he said at length, 'it wouldn't do. You mean well, George, but it would kill the show. We'll go on as before.'

'Will we?' said George, unpleasantly. 'Would you like to know what I'm going to do to you, then? I'm going to hit you very hard under the jaw, and I'm going to take hold of your neck and squeeze it till you lose consciousness, and then I'm going to drag you to the beach and tell people I had to hit you because you lost your head and struggled.'

Mr Mifflin pondered for the third time.
