And who were the ladies? If their names were not known, could not a description of their appearance be given? But no one had any definite memory on these points; they were just like other sightseers. Was there a tall woman with a brown cloak among them? Prescott put this question to several people, but drew no affirmative reply until he found an old coloured man who swept the halls. The sweeper thought that he did remember seeing such a figure on the lower floor, but he was not sure, and with that Prescott was forced to be content.
He felt that his search had not been wholly in vain, leading as it did to what might be called the shadow of a clue, and he resolved to continue it. There had been leaks before in the Confederacy, some by chance and some by design, notably an instance of the former when Lee's message to his lieutenant was lost by the messenger and found by a Northern sympathizer, thus informing his opponents of his plan and compelling him to fight the costly battle of Antietam. If he pursued this matter and prevented its ultimate issue, he might save the Confederacy far more than he could otherwise.
Richmond was a small city, difficult of entrance without a pass, and for two or three days Prescott, abandoning the society of his friends, trod its streets industriously, not neglecting the smallest and meanest among them, seeking always a tall figure in a brown dress and brown cloak. It became an obsession with him, and, as he now recognized, there was even more in it than a mere hunt for a spy. This woman troubled him; he wished to know who and what she was and why she, a girl, had undertaken a task so unfitting. Yet war, he remembered, is a destroyer of conventions, and the mighty upheaval through which the country was going could account for anything.
He found on the third day his reward in another glimpse of the elusive and now tantalizing brown figure under the brow of Shockoe Hill, strolling along casually, as if the beauty of the day and the free air of the heavens alone attracted.
The brown dress had been changed, but the brown cloak remained the same, and Prescott felt a pang of remorse lest he had done an injustice to a woman who looked so innocent. Until this moment he had never seen her face distinctly, save one glimpse, but now the brown hood that she wore was thrown back a little and there shone beneath it clear eyes of darkest blue, illuminating a face as young, as pure, as delicate in outline as he could have wished for in a sister of his own. No harm could be there. A woman who looked like that could not be engaged upon an errand such as he suspected, and he would leave her undisturbed.
But, second thought came. He put together again all the circumstances, the occasions upon which he had seen her, especially that day of the Morgan reception, and his suspicions returned. So he followed her again, at a distance now, lest she should see him, and was led a long and winding chase about the capital.
He did not believe that she knew of his presence, and these vague meanderings through the streets of Richmond confirmed his belief. No one with a clear conscience would leave such crooked tracks, and what other purpose could she have now save to escape observation until the vigilance of the sentinels, on edge over the robbery, should relax a little and she could escape through the cordon of guards that belted in Richmond.
She passed at last into an obscure side street and there entered a little brown wooden cottage. Prescott, watching from the corner, saw her disappear within, and he resolved that he would see her, too, when she came out again. Therefore he remained at the corner or near it, sauntering about now and then to avoid notice, but always keeping within a narrow circle and never losing sight of the house.
He was aware that he might remain there a long time, but he had a stiff will and he was bent upon solving this problem which puzzled and irritated him.
It was about the middle of the afternoon when he traced her to the cottage, but the fragment of the day remaining seemed long to him. Golden shadows hung over the capital, but at last the sun went down in a sea of flame and the cold night of winter gathered all within its folds.
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.
They came at last to a spot where there was a small break in the earthworks, and Prescott saw the sentinels walking their beats, gun on shoulder. Then the fugitive paused in the shadow of bushes and high grass and watched attentively.
The pursuit had become curiously unreal to Prescott. It seemed to him that he was in the presence of the mysterious and weird, but he was resolute to follow, and he wished only that she should resume her flight.
When the sentinels were some distance apart she slid between like a shadow, unseen and unheard, and Prescott, an adept at pursuit, quickly followed. They were now beyond the first line of earthworks, though yet within the ring of Richmond's outer defenses, but a single person with ordinary caution might pass the latter, too.
He followed her through bushes and clumps of trees which hung like patches
