Next there came a sound as of some heavy body, or object, being pushed across the room. Mark felt a draught of wind on his face, but it ceased instantly, and he knew that he was alone. He tried to work the bandage from over his eyes, and he endeavored to loosen his bonds, for he did not consider that this violated his promise. But it was of no effect. Presently he heard the moving, shoving sound again, and once more felt the wind on his face. Then he heard the voice of his captor speaking. "Here is food and drink. I'm going to untie your hands so you can eat, but mind, no fighting, for I'm a desperate man, and I won't stand any nonsense!" He fumbled about the bonds, and soon Mark was free to stand up and use his hands. The bandage was taken from his eyes, and he was able to peer about his prison by the light of a candle which his captor had brought. Mark's first glance was at the man. He was the same one who had emerged from the house to attack and drug him, but as for recognizing in him the person who had been at the bridge, this was impossible. As far as Mark could tell he had never seen the man before, nor did he answer the description given by Dick Johnson. There was little danger that Mark would attempt violence. He was too weak, and his jailer seemed a powerful fellow. Then, too, the lad felt ill from the effects of the drug. "Drink some water, and eat a bit, and you'll feel better," urged the man, which advice Mark followed, though, his appetite was not of the best, and he was much worried as to what his friends would think about his strange disappearance. "What do you intend to do with me?" asked Mark, when he felt a little better from the effects of the food and drink. The man had sat on an old soap box, and watched his captive while he ate. "Do with you? Why, I'm going to keep you here until your friends have left in the projectile," was the answer. "But why don't you want me to go with them?" "Oh, I have my reasons. You'll find out soon enough. You can't go, that's all." "But why do you take such an interest in me? Why didn't you capture my chum Jack, too, while you were about it?" "Two reasons. One was that Jack wouldn't answer my purpose, and the other was that I didn't have a chance to get him. You walked right into my trap, just when I was doing my best to think of another plan to get hold of you, since my first one failed." "But what is your purpose?" insisted the lad. "What do you want with me?" He thought perhaps if he questioned the man closely enough he might discover something that would give him a clew, or might aid him to escape. "You'll learn soon enough," was the answer. "Will you tell me your name?" asked Marie quietly. "No--why should I?" was the quick reply. "If I told you who I was you would at once know why I have made you a captive here. No; you shall hear all in good time, but that will not be until I am ready.
