"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."
