"You mean, there is—another woman?" she said with a brave effort. She even smiled accusingly.

"Some day I'll tell you all about it," he said evasively. "I—I suppose it would be all right for me to go round and call on Agatha this evening."

"She is not in town. California," said Betty.

"Great Scott! In California?" The dismay in his face was even greater than the relief of the moment before.

"Not exactly. She's on her way."

"By George, I wonder if I can catch her by wire? I must—I really must see her." He was so agitated that she observed beads of perspiration starting on his brow. She was mystified beyond description. Was he, after all, she found herself wondering, playing a part? Was it in his crafty heart to follow and kill Agatha Holmes!

"Oh, no,—you can't do that," she protested quickly. "Won't you—come out to dinner tonight?" she added somewhat confusedly. "We can talk over old times."

"Thanks, Betty, but I can't." At the same time he glanced uneasily at a cab which drove along close behind them.

"You were going to call upon Agatha," she pouted.

"But not at dinner-time," he said, mopping his brow. "I'll come up about nine, if I may."
