Prescott shivered as he trod his beat like a policeman, but he was of a tenacious fiber, and scorning alike the warnings of cold and hunger, he remained near the house, drawing closer and watching it more zealously than ever in the moonlight. His resolution strengthened, too; he would stay there, if necessary, until the sunset of the next day.
More hours passed at a limping gait. The murmur of the city died, and all was dark and still in the side street. Far into the night, nearly twelve, it must have been, when a figure stole from the cottage and glanced up the little ravine toward the main street, where Prescott stood invisible in the shadow of a high wooden fence.
She did not come by the front door, but stole out from the rear. He was convinced that he was right in his suspicions, and now every action of this unknown woman indicated guilt to his mind.
He crouched down in an angle of the fence, hidden completely by its shadow and the night, though he could see her well as she came up the little street, walking with light step and watching warily on every side. He noticed even then how strong and elastic her figure appeared and that every step was instinct with life and vitality. She must be a woman of more than common will and mould.
She came on, slightly increasing her speed, and did not see the dark figure of the man by the fence. A hood was drawn to her eyes and a fold of her cloak covered her chin. He could see now only a wisp of face like a sickle of a silver moon, and the feeling that disturbed him in the day did not return to him. He again imagined her cold and hard, a woman of middle age, battered by the world, an adventuress who did not fear to go forth in the night upon what he thought unholy errands.
She entered the main street, passed swiftly down it toward the barriers of the city, and Prescott, with noiseless footsteps, came behind; one shadow following the other.
None save themselves seemed to be abroad. The city was steeped in Sabbath calm and a quiet moon rode in a quiet heaven. Prescott did not stop now to analyze his feelings, though he knew that a touch of pique, and perhaps curiosity, too, entered into this pursuit, otherwise he should not have troubled himself so much with an unbidden task. But he was the hunter and she the hunted, and he was alive now with the spirit of the chase.
She turned toward the northwest, where the lines of earthwork were thinnest, where, in fact, a single person might slip between them in the darkness, and Prescott no longer had any doubt that his first surmise was correct. Moreover, she was wary to the last degree, looking cautiously on every side and stopping now and then to see that she was not followed. A fine moon sometimes shed its full rays upon her, and she seemed then to Prescott to be made of silver mist.
He, too, was most wary, knowing the need of it, and allowed the distance between them to lengthen, clinging meanwhile to the shadow of buildings and fences with such effect that when she looked back she never saw the man behind.
They passed into the suburbs, low and straggling, little groups of negro cabins stringing out now and then in the darkness, and the woman, save for her occasional pauses to see if she were pursued, kept a straight and rapid course as if she knew her mind and the way.
