"What change?" Violet asked. But she asked the question in a stifled voice and with her face averted from him.

"There was a constraint, an embarrassment," he said. "How can I explain it? I felt it rather than noticed it by visible signs. It seemed to me that you avoided being alone with me. I had a dread that you regretted the evening in the garden, that you were sorry we had agreed to live our lives together."

Violet did not protest. She did not turn to him with any denial in her eyes. She walked on by his side with her face still turned away from his, and for a little while she walked in silence. Then, as if compelled, she suddenly stopped and turned. She spoke, too, as if compelled, with a kind of desperation in her voice.

"Yes, you were right," she cried. "Oh, Dick, you were right. There was constraint, there was embarrassment. I will tell you the reason—now."

"I know it," said Dick with a smile.

Violet stared at him for a moment. She perceived his contentment. He was now quite unharassed by fear. There was no disappointment, no anger against her. She shook her head and said slowly:

"You can't know it."

"I do."

"Tell me the reason then."

"You were frightened by this business of the window."
