A few minutes later she passed him in the rotunda. For an instant their eyes met. There was a deep, searching expression in hers. Suddenly a deep flush covered her smooth cheek and her eyes fell. She hurried past, and he, stock-still with wonder and joy over this astounding exposition of confusion on her part, failed utterly to pursue an advantage that would have been seized upon with alacrity by the atavistic No. 12. He allowed her to escape!

Aroused to action too late, he bolted after her, only to see her enter a waiting taxi-cab and—yes, she did look back over her shoulder. She knew he would follow!

“She's going away,” said No. 7 in sepulchral tones.

“Evidently,” said Sampson. “Exceeding the speed limit while she is about it, too.”
