All that night he thought like boomerangs fly: an idea would shoot way off into the distance, all the way to a caravan in Hollywood and, for a moment, when he had got as far away from school and reality as it was possible to go, he was reasonably happy; then it would begin the return journey, thump him on the head, and leave him in exactly the place he had started from. And all the time it got nearer and nearer to the morning.
