The menace of her eyes glittered upon him. If her strength of body had been equal to it at that moment, she would have leapt forward and strangled him with her bare hands. Knowledge of her own peril, of the Nemesis that was sweeping upon her, had not yet entered her disordered mind.

John made—in pursuance of his prearranged plan of action—no effort to stay her as she went towards the door. But as Mrs. Beecher Monmouth paused and cast a final look at him, a sudden doubt crept into her eyes. For John had gone to the window. He appeared no longer to be occupied with her. His back was towards her, and presently he lifted a whistle to his lips and blew two short, shrill blasts.

"Is that you, Davis?"

"Yes, sir!"
