Nick considered the matter in all its bearings while he stirred his coffee.
"No," he said finally; "I think I shall stay at home with you this morning."
"How do you know I am not going?" said Olga.
Nick grinned. "I'm awfully good at guessing, Olga mia."
She smiled rather wanly. "Well, I'm not going, as a matter of fact. I had a stupid sort of night."
Nick nodded. "I shan't take you out to dinner again for a long time."
"It wasn't that," she said. "At least, I don't think so. It was that song. Why did Noel sing it?"
"For reasons best known to himself," said Nick, taking out his cigarette-case.
She rose and went round to his side to strike a match for him, but reaching him she suddenly knelt and clasped her arms about his neck.
"Nick," she whispered, "I'm frightened."
