"Good Heavens!" exclaimed Jill.

She turned quickly round again.

"What's the matter? Do you know her? Somebody you don't want to meet?"

"It's Lady Underhill! And Derek's with her!"

Wally had been lifting his glass. He put it down rather suddenly.

"Derek?" he said.

"Derek Underhill. The man I'm engaged to marry."

There was a moment's silence.

"Oh!" said Wally thoughtfully. "The man you're engaged to marry? Yes, I see!"

He raised his glass again, and drank its contents quickly.
