"You wouldn't do that!" said Eustace piteously.

"I would and will."

"But I shouldn't be any good at the piano. I've forgotten how the thing
used to go."

"You haven't done anything of the kind. I come in and say, 'Hullo,
Ernest!' and you say 'Hullo, Frank!' and then you help me tell the
story about the Pullman car. A child could do your part of it."

"Perhaps there is some child on board...."

"No! I want you. I shall feel safe with you. We've done it together
before."

"But honestly, I really don't think ... it isn't as if...."

Sam rose and extended a finger towards the bell.

"Stop! Stop!" cried Eustace Hignett. "I'll do it!"

Sam withdrew his finger.

"Good!" he said. "We've just got time for a rehearsal while you're
dressing. 'Hullo, Ernest!'"

"Hullo, Frank," said Eustace Hignett, brokenly, as he searched for his
unfamiliar trousers.
