There was a great silence. Christopher and I looked at each other and decided that something must be done.

I cleared my throat quietly. "Cooee!" I fluted.

Dorothy began to sing a hymn in a loud voice.

And then Cecilia came into the room.

Now Cecilia is Christopher's mother and my sister. You will understand that neither Christopher nor I would care to appear ridiculous in front of her. So we kept quiet.

"Hallo, Dorothy," said Cecilia; "all by yourself? Where's Christopher?"

"I'm reading Christopher's book," said Dorothy, ignoring the question. "May I?"

"Of course, dear," said Cecilia, sitting down. There was a lot more silence. It grew very hot and uncomfortable under the table.

"What shall we do, Uncle?" whispered Christopher.

"Come on," I said desperately. We crawled out and stood up.
