Durrance stepped across the window sill and stood by the side of Mrs. Adair. The last slip which Ethne had made betrayed her inevitably to the man who had grown quick. There could be only one reason for her sudden unexplained and secret flight. He had told her that Feversham had wandered south from Wadi Halfa into the savage country; he had spoken out his fears as to Feversham's fate without reserve, thinking that she had forgotten him, and indeed rather inclined to blame her for the callous indifference with which she received the news. The callousness was a mere mask, and she had fled because she no longer had the strength to hold it up before her face. His first suspicions had been right. Feversham still stood between Ethne and himself and held them at arm's length.

"She ran as though she was in great trouble and hardly knew what she was doing," Mrs. Adair continued. "Did you cause that trouble?"

"Yes."

"I thought so, from what I heard you say."

Mrs. Adair wanted to hurt, and in spite of Durrance's impenetrable face, she felt that she had succeeded. It was a small sort of compensation for the weeks of mortification which she had endured. There is something which might be said for Mrs. Adair; extenuations might be pleaded, even if no defence was made. For she like Ethne was overtaxed that night. That calm pale face of hers hid the quick passions of the South, and she had been racked by them to the limits of endurance. There had been something grotesque, something rather horrible, in that outbreak and confession by Durrance, after Ethne had fled from the room. He was speaking out his heart to an empty chair. She herself had stood without the window with a bitter longing that he had spoken so to her and a bitter knowledge that he never would. She was sunk deep in humiliation. The irony of the position tortured her; it was like a jest of grim selfish gods played off upon ineffectual mortals to their hurt. And at the bottom of all the thoughts rankled that memory of the extinguished lamp, and the low, hushed voices speaking one to the other in darkness. Therefore she spoke to give pain and was glad that she gave it, even though it was to the man whom she coveted.

"There's one thing which I don't understand," said Durrance. "I mean the change which we both noticed in Ethne to-night. I mistook the cause of it, that's evident. I was a fool. But there must have been a cause. The gift of laughter had been restored to her. Her gravity, her air of calculation, had vanished. She became just what she was five years ago."

"Exactly," Mrs. Adair answered. "Just what she was before Mr. Feversham disappeared from Ramelton. You are so quick, Colonel Durrance. Ethne had good news of Mr. Feversham this morning."

Durrance turned quickly towards her, and Mrs. Adair felt a pleasure at his abrupt movement. She had provoked the display of some emotion, and the display of emotion was preferable to his composure.

"Are you quite sure?" he asked.

"As sure as that you gave her the worst of news to-night," she replied.
