Slim's sister! There was no mistaking the sweetly serious eyes, the smiling lips with which he had grown familiar in the yellowish picture. She was older, thinner, the youthful roundness was gone, but beyond question she was Slim's sister! She passed the table without a glance and in something like a panic he watched her leave the room. He would never see her again! This was the only chance he'd ever have. Should he sit there calmly and let it pass! He laid his napkin on the table, and explained as he rose hastily: "There's someone out there I must see. I'll be back, but don't wait for me." He did not know himself what he meant to say or do, beyond the fact that he would speak to her even if she snubbed him. She had stepped into the cloak room for her wrap and Sprudell was waiting in the corridor. Immediately when he saw Bruce he guessed his purpose and the full significance of a meeting between them rushed upon him. He was bent desperately upon preventing it. Sprudell took the initiative and advanced to meet him. "If you've anything to say to me, Bruce, I'll meet you to-morrow." "I've nothing at all to say to you except to repeat what I said to you in Bartlesville. I told you then I thought you'd lied and now I know it. That's Slim's sister." "That is Miss Dunbar." "I don't believe you." "I'll prove it." "Introduce me." "It isn't necessary; besides," he sneered, "she's particular who she knows." "Not very," Bruce drawled, "or she wouldn't be here with you." He added obstinately: "That's Slim's sister." Helen came from the cloak room and stopped short at seeing Bruce and Sprudell in conversation. Certainly this was an evening of surprises. "Are you ready, Miss Dunbar?" Sprudell placed loud emphasis upon the name. She nodded. Sprudell, who was walking to meet her, glanced back at Bruce with a smile of malice but it was wasted upon Bruce, who was looking at the girl. Why should there be that lurking horror and hostility in her eyes? What had Sprudell told her? On a sudden desperate impulse and before Sprudell could stop him, he walked up to her and asked doggedly, though his temerity made him hot and cold: "Why do you look at me as if I were an enemy? What has Sprudell been telling you?" "I forbid you to answer this fellow--" Sprudell's voice shook and his pink face had again taken on the curious chalkiness of color which it became under stress of feeling. Forgetting prudence, his deferential pose, forgetting everything that he should have remembered in his rage at Bruce's hardihood, and the fear of exposure, he shook his finger threateningly before Helen's face. On the instant her chin went haughtily in the air and there was a dangerous sparkle in her eyes as she replied: "You are presumptuous, Mr. Sprudell. Your manner is offensive--_very_."
