"Not quite lately," said Nick. "I've been smoking. I wonder you didn't notice it."

His tone was somehow repressive, but she ignored it with a growing temerity. After all, he did not seem such an alarming person on a nearer acquaintance.

"Does smoking do as well as eating?" she asked.

"Much better," said Nick promptly. "Care to try?"

She shook her head in the darkness. "I don't think you are telling the truth," she said.

"What?" said Nick.

He spoke carelessly, but she did not repeat her assertion. A sudden shyness descended upon her, and she became silent. Nick was quiet too, and she wondered what was passing in his mind. But for the tenseness of the arm that encircled her, she could have believed him to be dozing. The silence was becoming oppressive when abruptly he broke it.

"See!" he said. "Here comes the dawn!"

She started and stared in front of her, seeing nothing.

"Over to your left," said Nick. And turning she beheld a lightening of the darkness high above them.
