“Don't take such risks,” he said. “I wouldn't have your job, Mr. Wilton, for all the old man's money. If we hadn't happened up here, you'd have been done for this time.” “In God's name, man, what does all this mean?” I gasped. The man looked at me in evident surprise. “They've got a fresh start, I guess,” he said. “You'd better get some of the men up here. Mr. Richmond sent us up to bring this letter.” He was gone silently, and I was left in the darkness. I struck a match, lighted the gas once more, and, securing the revolver, looked to the letter. The envelope bore no address. I tore it open. The lines were written in a woman's hand, and a faint but peculiar perfume rose from the paper, it bore but these words: “Don't make the change until I see you. The money will be ready in the morning. Be at the bank at 10:30.” The note, puzzling as it was, was hardly an addition to my perplexities. It was evident that I had been plunged into the center of intrigue, plot and counterplot. I was supposed to have possession of somebody's boy. A powerful and active enemy threatened me with death. An equally active friend was working to preserve my safety. People of wealth were concerned. I had dimly seen a fragment of the struggling forces, and it was plain that only a very rich person could afford the luxury of hiring the bravos and guards who threatened and protected me. How wide were the ramifications of the mystery? Whose was the boy, and what was wanted of him? Had he been stolen from home and parents? Or was he threatened with mortal danger and sent into hiding to keep him from death? The fate of Henry showed the power of those who were pursuing me. Armed as he was with the knowledge of his danger, knowing, as I did not, what he had to guard and from what he had to guard it, he had yet fallen a victim. I could not doubt that he was the man assaulted and stabbed in the alley below. But the fact that no trace of him or of a tragedy was to be found gave me hope that he was still alive. Yet, at best, he was wounded and in the hands of his enemies, a prisoner to the men who had sought his life. It must be, however, that he was not yet recognized. The transfer of the chase to me was proof that the scoundrels had been misled by the resemblance between us, and by the letters found in the coat. They were convinced that he was Giles Dudley, and that I was Henry Wilton. As long as there was hope that he was alive I would devote myself to searching for him and to helping him to recover his liberty. As I was hoping, speculating, planning thus, I was startled to hear a step on the stair. The sound was not one that need be thought out of place in such a house and neighborhood even though the hour was past four in the morning. But it struck a chill through me, and I listened with growing apprehension as it mounted step by step.
