Eustace took up his cup in heavy silence, and drained it. Then he rose. "Come along, Miss Bathurst!" But Dinah remained seated. "I am very sorry," she said. "But I can't." "Oh, nonsense!" He smiled very suddenly and winningly upon her. "Surely you won't disappoint me!" She shook her head. Her eyes were wistful. "I'm disappointing myself quite as much. But I mustn't. The Colonel has gone to bed with dyspepsia, and Lady Grace and Rose have gone too by this time. I can't come down again." "Nonsense!" he said again. "You want to. You know you do. No one pays any attention to Mrs. Grundy out here. She simply doesn't exist. Scott can come and play propriety. He's staid enough to chaperon a whole girls' school." "Thanks, old chap," said Scott. "But I'm not coming down again, either." Eustace looked over his head. "Then you must, Isabel. Come along! Just to oblige Miss Bathurst! It won't hurt you to sit in a safe corner for one dance." Isabel looked up at him with a startled expression, as of one trapped. "Oh, don't ask me!" she said. "I couldn't!" "No, don't!" said Dinah. "It isn't, fair to bother anyone else on my account! I'm dreadfully sorry to have to refuse. But--in any case--I ought not to come." "What of that?" said Eustace lightly. "Do you always do what you ought? What a dull programme!" Dinah flushed. "Dull but respectable," she said, with a touch of spirit. He laughed. "But I'm not asking you to do anything very outrageous, and I shouldn't ask it at all if I didn't know you wanted to do it. Besides, you promised. It's generally considered the respectable thing to do to keep one's promises." That reached Dinah. She wavered perceptibly. "Lady Grace will be so vexed," she murmured. He snapped his fingers in careless disdain. She turned appealingly to Scott. "I think I might go--just for one dance, don't you?" Scott's pale eyes met hers with steady comradeship. "I think I shouldn't," he said. Eustace turned as if he had not heard and strolled to the door. He opened it, and at once the room was filled with the plaintive alluring strains of waltz-music. He stood and looked back. Dinah met the look, and suddenly she was on her feet. He held out his hand to her with a smile half-mocking, half-persuasive. The music swung on with a subtle enchantment. Dinah uttered a little quivering laugh, and went to him. In another moment the door closed, and they stood alone in the passage. "I knew you wanted to," said Eustace, smiling down into her eyes with the arrogance of the conqueror. Dinah was panting a little as one who had suffered a sudden strain. "Of course I wanted to," she returned. "But that doesn't make it right." He pressed her hand to his heart for a moment, and she caught again a glimpse of that fire in his eyes that had so thrilled her. She could not meet it. She stood in palpitating silence. "Where is the use of fighting against fate?" he asked her softly. "A gift of the gods is never offered twice."
