"What is?" asked Milly.

"The bacon row."

"Oh, how dare you!" cried Milly in a voice of rapture. "Supposing you were heard!"

"There's no one to hear me—anyhow, it is rot!"

Milly danced. "You'll catch it if mother hears you!" Her fair curls bobbed as she skipped round the room.

"Mind that cup," warned Joan.

But it was too late; the cup fell crashing to the floor. Just then Mrs. Ogden came in.

"Who broke that cup?"

There was silence.
