"I beg your pardon. You are become so critical of words and phrases. To take us, I'll say."

"That wouldn't be a very agreeable walk, Helen, whilst you are in this strange mood. What does it all mean? I never foresaw the possibility of misunderstandings such as this between us. Is it I who am to blame, or you? Have I offended you?"

"Yes I will go," was the answer, spoken very quietly. "And to-morrow morning I will return to London."

She moved away.

"Irene!"
