Then there was sound as of a man praying, and the prayer was broken by sobs; and again I thought there were two men. And then there was noise of a man moving about, and a long smothered groan, as of one in agony of spirit. Fearful that the door might be flung open in my face, I tiptoed back to my room, and silently turned the key, as thoroughly mystified as ever I had been in the strange events that had crowded my life since I had entered the city. CHAPTER XVII IN A FOREIGN LAND I stood long by my own door, irresolute, listening, hoping, fearing, my brain throbbing with the effort to seize some clue to the maze of mysteries in which I was entangled. Was the clue behind those locked doors? Did the man whose groans and prayers had startled me hold the heart of the mystery? The groans and prayers, if they continued, could be heard no longer through the double doors, and I seated myself by the desk and took account of the events that had brought me to my present position. Where did I stand? What had I accomplished? What had I learned? How was I to reach the end for which I struggled and bring to justice the slayer of my murdered friend? As I passed in review the occurrences that had crowded the few weeks since my arrival, I was compelled to confess that I knew little more of the mysteries that surrounded me than on the night I arrived. I knew that I was tossed between two opposing forces. I knew that a mysterious boy was supposed to be under my protection, and that to gain and keep possession of him my life was sought and defended. I knew that Doddridge Knapp had caused the murder of Henry Wilton, and yet for some unfathomable reason gave me his confidence and employment under the belief that I was Henry Wilton. But I had been able to get no hint of who the boy might be, or where he was concealed, or who was the hidden woman who employed me to protect him, or why he was sought by Doddridge Knapp. Mother Borton's vague hints seemed little better than guess-work. If she knew the name of the boy and the identity of the woman, she had some good reason for concealing them. It flashed over my mind that Mother Borton might herself be the mysterious employer. I had never yet seen a line of her handwriting, and the notes might have come from her. It was she who first had told me that my men were already paid, and a few hours later I had found the note from my employer assuring me that the demands were fully settled. Could it be that she was the woman with whom Doddridge Knapp was battling with a desperate purpose that did not stop at murder? The idea was gone as soon as it came. It was preposterous to suppose that these two could feel so overwhelming an interest in the same child.
