But Callum by now was not so easily restrained. His face was quite pale, and he was moving toward the old English grill-room, where Hibbs happened to be, consuming a brandy-and-soda with a friend of about his own age. Callum entered and called him.

“Oh, Hibbs!” he said.

Hibbs, hearing his voice and seeing him in the door, arose and came over. He was an interesting youth of the collegiate type, educated at Princeton. He had heard the rumor concerning Aileen from various sources—other members of the club, for one—and had ventured to repeat it in Pethick’s presence.

“What’s that you were just saying about my sister?” asked Callum, grimly, looking Hibbs in the eye.

“Why—I—” hesitated Hibbs, who sensed trouble and was eager to avoid it. He was not exceptionally brave and looked it. His hair was straw-colored, his eyes blue, and his cheeks pink. “Why—nothing in particular. Who said I was talking about her?” He looked at Pethick, whom he knew to be the tale-bearer, and the latter exclaimed, excitedly:

“Now don’t you try to deny it, Hibbs. You know I heard you?”

“Well, what did I say?” asked Hibbs, defiantly.

“Well, what did you say?” interrupted Callum, grimly, transferring the conversation to himself. “That’s just what I want to know.”

“Why,” stammered Hibbs, nervously, “I don’t think I’ve said anything that anybody else hasn’t said. I just repeated that some one said that your sister had been very friendly with Mr. Cowperwood. I didn’t say any more than I have heard other people say around here.”

“Oh, you didn’t, did you?” exclaimed Callum, withdrawing his hand from his pocket and slapping Hibbs in the face. He repeated the blow with his left hand, fiercely. “Perhaps that’ll teach you to keep my sister’s name out of your mouth, you pup!”
