Flora leaned back with a sigh of relief. The mere sensation of being borne along at such a rate, the sight of houses, lamp-posts, even people here and there, flitting away from the eye, unable to interrupt her course, or even to glimpse her identity, gave her a feeling of safety. The more she was getting into the residence part of the city, the more deserted the streets, the closer shut the windows of the houses, the more it seemed to her as if the night itself covered and abetted her flight. So swiftly she went it was only a wonder how the cab held together. She had never traveled more rapidly in her light and silent carriage. Now they whirled the corner and plunged at the steep rise of a cross street. Just above, over the crown of the hill, she saw the sky, moonless, blackish, spattered with stars. Then against it a little fluttering shape like a sentinel wisp--the only living thing in sight. It was incredible, impossible, horrible that he should be there, in front of her, waiting for her, who had driven so fast--too fast, it had seemed, for human foot to follow. By what unimaginable route had he traveled? She was ready to believe he had flown over the housetops. And above all other horrors, why was he pursuing her? The carriage was abreast the Chinaman now, and immediately he took up his trot, for a little while keeping up, dodging along between light and shadow, presently falling behind. At intervals she heard the patter, patter, patter of his footsteps following; at intervals she lost the sound, and shadows would engulf the figure, and she would wait in a panic for its reappearance. For she knew it was there somewhere, on one side of the street or the other. But, oh, not to see it! To expect at any moment it might start up again--Heaven knew where, perhaps at her very carriage window. Her unconscious hand was doubled to a fist upon her breast, fast closed upon the sapphire. With all her body braced, she leaned and looked far backward, and far forward, and now for a long time saw nothing. The distance was empty. The glare of arc-lights showed her the shadows of her own progress--the shadow of her vehicle shooting huge and misshapen now on the cobbles, now along a blank wall, wheels, body and driver, all lurching like one; now heaped on each other, now tenuously drawn out, now twisting themselves into shapes the mind could not account for. For here, whirling the corner, the carriage seemed to wave an arm, and now between the wheels, fast twinkling, she saw a pair of legs. She leaned and looked, so mesmerized with this grotesque appearance that it scarcely troubled her that all the way down the last long hill she knew it must be that a man was running at her wheel.
