"Don't, please!" he said gently. "It has been good to me to be with you. How good you never can know." He paused and then looked keenly at her.
"Did you rest well last night, your first night under the stars? Did you hear the coyotes, or feel at all afraid?"
Her colour fled, and she dropped her glance to Billy's neck, while her heart throbbed painfully.
He saw how disturbed she was.
"You were afraid," he charged gently. "Why didn't you call? I was close at hand all the time. What frightened you?"
"Oh, it was nothing!" she said evasively. "It was only for a minute."
"Tell me, please!" his voice compelled her.
"It was just for a minute," she said again, speaking rapidly and trying to hide her embarrassment. "I woke and thought I heard talking and you were not in sight; but it was not long before you came back with an armful of wood, and I saw it was almost morning."

At last he said in a low voice full of feeling: "You heard me?"
Her eyes, which he had held with his look, wavered, faltered, and drooped. "I was afraid," he said as her silence confirmed his conviction. "I heard some one stirring. I looked and thought I saw you going back to your couch." There was grave self-reproach in his tone, but no reproach for her. Nevertheless her heart burned with shame and her eyes filled with tears. She hid her glowing face in her hands and cried out: "I am so sorry. I did not mean to be listening. I thought from the tone of your voice you were in trouble. I was afraid some one had attacked you, and perhaps I could do something to help----"
