"You are so seldom off your guard. Only indeed at rare times when you play. Once before when you played that overture you were off your guard. I thought that if I could get you to play it again to-night—the overture which was once strummed out in a dingy café at Wadi Halfa—to-night again I should find you off your guard."
His words took her breath away and the colour from her cheeks. She got up slowly from her chair and stared at him wide-eyed. He could not know. It was impossible. He did not know.
But Durrance went quietly on.
"Well? Did you take back your feather? The fourth one?"
These to Ethne were the incredible words. Durrance spoke them with a smile upon his face. It took her a long time to understand that he had actually spoken them. She was not sure at the first that her overstrained senses were not playing her tricks; but he repeated his question, and she could no longer disbelieve or misunderstand.
"Who told you of any fourth feather?" she asked.
"Trench," he answered. "I met him at Dover. But he only told me of the fourth feather," said Durrance. "I knew of the three before. Trench would never have told me of the fourth had I not known of the three. For I should not have met him as he landed from the steamer at Dover. I should not have asked him, 'Where is Harry Feversham?' And for me to know of the three was enough."
"How do you know?" she cried in a kind of despair, and coming close to her he took gently hold of her arm.
"But since I know," he protested, "what does it matter how I know? I have known a long while, ever since Captain Willoughby came to The Pool with the first feather. I waited to tell you that I knew until Harry Feversham came back, and he came to-day."
Ethne sat down in her chair again. She was stunned by Durrance's unexpected disclosure. She had so carefully guarded her secret, that to realise that for a year it had been no secret came as a shock to her. But, even in the midst of her confusion, she understood that she must have time to gather up her faculties again under command. So she spoke of the unimportant thing to gain the time.
