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.
