"Good-morning, Bateman."

"How did you recognise my voice?"

"It is not so long since I heard it last. Besides, I was expecting you."

"When may I see you?"

"Unless you have anything better to do perhaps you'll dine with us to-night."

"You know very well that I couldn't possibly have anything better to do."

"I suppose that you're full of news?"

He thought he detected in her voice a note of apprehension.

"Yes," he answered.
