A VAIN PURSUIT  
Youth was strong in Harry, and, while he danced and the music played, he forgot all about the incident in the smoking-room. With him it was just one pretty girl after another. He had heart enough for them all, and only one who was so young and who had been so long on battlefields could well understand what a keen, even poignant, pleasure it was to be with them.
 
Those were the days when a ball lasted long. Pleasures did not come often, but when they came they were to be enjoyed to the full. But as the morning hours grew the manner of the older people became slightly feverish and unnatural. They were pursuing pleasure and forgetfulness with so much zeal and energy that it bore the aspect of force rather than spontaneity. Harry noticed it and divined the cause. Beneath his high spirits he now felt it himself. It was that looming shadow in the North and that other in that far Southwest hovering over lost Vicksburg. Serious men and serious women could not keep these shadows from their eyes long.
 
The incident of the smoking-room and the missing map came back to him with renewed force. It could not have walked away. They had searched the room and the court so thoroughly that they would have found it, had it been there. The disappearance of a document, which men of authority and knowledge had built up almost unconsciously, puzzled and alarmed him.
 
It was almost day when he and Dalton left. They paid their respects to Mr. and Mrs. Curtis, and said many good-bys to "the girls they left behind them." Then they went out into the street, and inhaled great draughts of the cool night air.
 
"A splendid night," said Dalton.
 
"Yes, truly," said Harry.
 
"I hope you didn't propose to more than six girls."
 
"To none. But I love them all together."
 
"I'm glad to hear it, because you're entirely too young to marry, and your occupation is precarious."
 
"You needn't be so preachy. You're not more'n a hundred years old yourself."
 
"But I'm two months older than you are and often two months makes a vast difference, particularly in our cases. I notice about you, Harry, at times, a certain juvenility which I feel it my duty to repress."
 
"Don't do it, George. Let's enjoy it while we can, because as you say my occupation is precarious and yours is the same."
 
They stopped at the corner of the iron fence enclosing the Curtis home, in which many lights were still shining. It was near a dark alley opening on the street and running by this side of the house.
 
"I'm going to see what's behind Mr. Curtis's house," said Harry.
 
Dalton stared at him.
 
"What's got into your head, Harry!" he exclaimed. "Do you mean to be a burglar prowling about the home of the man who has entertained you?"
 
Harry hesitated. He was sorry that Dalton was with him. Then he could have gone on without question, but he must make some excuse to Dalton.
 
"George," he said at last, "will you swear to keep a secret, a most important one which I am pledged to tell to nobody, but which I must confide in you in order to give a good reason for what I am about to do."
 
"If you are pledged to keep such a secret," replied Dalton, "then don't explain it to me. Your word is good enough, Harry. Go ahead and do what you want to do. I'll ask nothing about any of your actions, no matter how strange it may look."
 
"You're a man in a million, George. Come on, your confidence is going to be tested. Besides, you'll run the danger of being shot."
 
But Dalton followed him fearlessly as he led the way down the alley. Richmond was not lighted then, save along the main streets, and a few steps took them into the full dark. The brilliant windows threw bright bands across the lines, but they themselves were in darkness.
 
The alley ran through the next street and so did the Curtis grounds. They were as extensive in the rear of the house as in front, and contained small pines carefully trimmed, banks of roses and two grape arbors. Harry could hear no sound of any one stirring among them, but people, obviously the cooks and other servants, were talking in the big kitchen at the rear of the house.
 
The street itself running in the rear of the building was as well lighted as it was in front, but Harry saw no one in it save a member of the city police, who seemed to be keeping a good watch. But as he did not wish to be observed by the man he waited a little while in the mouth of the alley, until he had moved on and was out of sight.
 
"Now, George," he said, "you and I are going to do a little scouting. You know I'm descended from the greatest natural scout and trailer ever known in the West, one whose senses were preternaturally acute, one who could almost track a bird in the air by its flight."
 
"Yes, I've heard of the renowned Henry Ware, and I know that you've inherited a lot of his skill and intuition. Go ahead. I promised that I would help you and ask no questions. I keep my word."
 
Harry climbed silently over the low fence, and Dalton followed in the same manner. The light from the street and house did not penetrate the pines and rosebushes, where Harry quickly found a refuge, Dalton as usual following him.
 
"What next?" whispered Dalton.
 
"Now, I do my trailing and scouting, and you help me all you can, George, but be sure you don't make any noise. There's enough moonlight filtering through the pines to show the ground to me, but not enough to disclose us to anybody twenty feet away."
 
He dropped to his hands and knees, and, crawling back and forth, began to examine every inch of ground with minute care, while Dalton stared at him in amazement.
 
"I'd help," whispered Dalton, "if I only knew what you were doing."
 
"Suppose, George, that somebody wanted to see the Curtis house, and yet not be seen, wanted to observe as well as he could, without detection, what was going on there. He'd watch his chance, jump over the fence as we have done and enter this group of pines. He could ask no finer point of observation. We are perfectly hidden and yet we can see the whole rear of the house and one side of it."
 
"So we can. I infer that you are looking for some one who you think has been acting as a spy."
 
"Ah! here we are. The earth is a bit soft by this pine, and I see the trace of a footstep! And here is another trace, close by it, undoubtedly the imprint of the other foot. It's as plain as day."
 
Dalton knelt, looked at the traces, and shook his head. "I can't make out any of them," he said. "I see nothing but a slight displacement of the grass caused by the wind."
 
"That's because you haven't my keen eye, an inherited and natural ability as a trailer, although you may beat me out of sight in other things. The shape of these traces indicates that they were made by human feet, and their closeness together shows that the man stood looking at the house. If he had been walking along they would be much wider apart."
 
He examined the traces again with long and minute care.
 
"The toes point toward the house, consequently he was looking at it," he said. "He was a heavy man, and he stood here a long time, not moving from his tracks. That's why he left these traces, which are so clear and evident to me, George, although they're hidden from a blind man like you."
 
"Well, what of it?"
 
"Nothing much to you, but a lot to me."
 
He rose to his feet and examined the boughs of the pine.
 
"As I thought," he whispered with great satisfaction. "Despite his courage and power over himself, both of which were very great, he became a little excited. Doubtless he saw something that stirred him deeply."
 
"What under the stars are you talking about, Harry?"
 
"See, he broke off three twigs of the pine. Just snapped them in two with nervous fingers. Here are pieces lying on the ground. Now, a man does that sort of thing almost unconsciously. He will not reach up for the twig or down for it, but he breaks it because it presents itself to him at the corner of his eye. This man was six feet in height or more and built very powerfully. I think I know him! Yes, I'm sure I know him! Nor is it at all strange that he should be here."
 
"Shall we make a thorough search for him among the pines? You say he's tall and built powerfully. But maybe the two of us could master him, and if not we could call for help."
 
"Too late, George. He left a long time ago, and he took with him what he wanted. We needn't look any farther."
 
"Lead on, then, King of Trailers and Master of Secrets! If the mighty Caliph, Haroun al Kenton, wishes to prowl in these grounds, seeking the heart of some great conspiracy, it is not for his loyal vizier, the Sheikh Ul Dalton to ask him questions."
 
"I'm not certain that a vizier is a sheikh."
 
"Nor am I, but I'm certain that I want to go home and go to bed. Vikings of the land like ourselves can't stand much luxury. It weakens the tissues, made strong on the march and in the fields."
 
They left the grounds silently and unobserved and soon were in their own quarters, where they slept nearly the whole day. Then they spent three or four days more in the social affairs which were such a keen pleasure to them after such a long deprivation. But wherever they went, and they were in demand everywhere, Harry was always looking for somebody, a man, tall, heavy and broad shouldered, not a man who would come into a room where he was, or who would join a company of people that he had joined, but one who would hang upon the outskirts, and hide behind the corners of buildings or trees. He did not see the shadow, but once or twice he felt that it was there.
 
The officer, Bathurst, told him one night that some important papers had been stolen from the White House of the Confederacy itself.
 
"They pertain to our army," said Bathurst, "and they will be of value to the enemy, if they reach him."
 
"I'm quite certain that the most daring and dangerous of all northern spies is in Richmond," said Harry.
 
Then he told Bathurst of Shepard and of the trails that he had seen among the pines behind Curtis's house.
 
"Do you think this man got our map?" asked Bathurst.
 
"It may have been so. Perhaps he was hidden in the court and when he saw us go out, leaving the map on the table, he slipped in at the window and seized it."
 
"But the court was enclosed. He would have had to go with the paper through the house itself."
 
"That's where my theory fails. I can provide for his taking the paper, but I can't provide for his escape."
 
"I'll tell the General about it. I think you're right, Harry. I've heard of Shepard myself, and he's worth ten thousand men to the Yankees. It's more than that. At such a critical stage of our affairs he might ruin us. We'll make a general search for him. We'll rake the city with a fine tooth comb."
 
The search was made everywhere. Soldiers pried in every possible place, but they found nobody who could not give an adequate account of his presence in Richmond. Harry felt sure nevertheless that Shepard was somewhere in the capital, protected by his infinite daring and resource, and they received the startling news the next day after the search that a messenger sent northward with dispatches for Lee had been attacked only a short distance from the city. He had been struck from behind, and did not see his assailant, but the wound in the head—the man had been found unconscious—and the missing dispatches were sufficient proof.
 
A night later precious documents were purloined from the office of the Secretary of War and a list of important earthworks on the North and South Carolina coast disappeared from the office of the Secretary of the Navy. Alarm spread through all the departments of the Confederacy. Some one, spy and burglar too, had come into the very capital, and he was having uncommon success.
 
Harry had not the least doubt that it was Shepard, and he was filled with an ambition to capture this man, whom he really liked. If Shepard were caught he would certainly be hanged, but then a spy must take his chances.
 
They heard meanwhile that General Lee had gone to a former camp of his on the Opequan, but that later in response to maneuvers by General Meade, he moved to a position near Front Royal. No orders came for Harry or Dalton to rejoin him, and, as a period of inactivity seemed to be at hand, they were glad to remain a while longer in Richmond. They still stayed with the Lanhams, who refused to take any pay, although the two young officers, chipping together, bought for Mrs. Lanham a little watch which had just come through the blockade from England.
 
Thus their days lengthened in Richmond, and, despite the shadow of the spy and his doings which was over Harry, they were still very pleasant. The members of the Mosaic Club, although older men, made much of them, and Harry and Dalton, being youths of sprighty wit, were able to hold their own in such company. The time had now passed into August, and they sat one afternoon in the lobby of the big hotel with their new friends. Richmond without was quiet and blazing in the sun. Harry had received a second letter from his father from an unnamed point in Georgia. It did not contain much news, but it was full of cheerfulness, and it intimated in more than one place that Bragg's army was going to strike a great blow.
 
All eyes were turned toward the West. The opinion had been spreading in the Confederacy that the chief danger was on that line. It seemed that the Army of Northern Virginia could take care of anything to the north and east, but in the south and west affairs did not go well.
 
"It's a pity that General Bragg is President Davis' brother-in-law," said Randolph.
 
"Why?" asked Daniel.
 
"Then he wouldn't be in command of our Western Army."
 
"Bragg's a fighter, though."
 
"But not a reaper."
 
"What do you mean?"
