Count Hannibal by Stanley J. Weyman

So far excitement had supported Tignonville in his escape. It was only when he knew himself safe, when he heard Madame St. Lo's footstep in the courtyard and knew that in a moment he would see her, that he knew also that he was failing for want of food. The room seemed to go round with him; the window to shift, the light to flicker. And then again, with equal abruptness, he grew strong and steady and perfectly master of himself. Nay, never had he felt a confidence in himself so overwhelming or a capacity so complete. The triumph of that which he had done, the knowledge that of so many he, almost alone, had escaped, filled his brain with a delicious and intoxicating vanity. When the door opened, and Madame St. Lo appeared on the threshold, he advanced holding out his arms. He expected that she would fall into them.

But Madame only backed and curtseyed, a mischievous light in her eyes.
