Bound and helpless, lying on their backs and staring into the gloom of the small chamber into which they had been thrown, Miles and Ward had time to ponder their desperate situation. Spiro was delaying their death until the workers of Apex would have time to gather and witness it. At first they had struggled to loosen their bonds, but such efforts served only to tighten them. Then they had tried the trick of rolling together so that the fingers of one might endeavor to undo the knots securing the other. On a memorable occasion in Turkey they had freed themselves in this manner. But the attempts proved fruitless now. The floor of the chamber was smooth, nor could they find any rough projection on which to saw the cords. Exhausted, they finally desisted. The same thought was in both minds: Were they doomed to die in this strange world, fated never to see Earth again? Well, a soldier of fortune must expect to meet with reverses. Still, it was a tough break. After a long silence Ward said, "How were we to know that the heads lived on the blood of the people?" "Would it have made any difference if we had known?" asked Miles. "Perhaps not." Ward tried to shrug his shoulders. "After all, we have fought to maintain systems not much better. There is little difference, save in degree, between draining the life-blood of a race and robbing it of the fruits of its labor." "But sometimes we fought to liberate people," protested Miles. "Yes, I like to think of that. It's good to have something to our credit when we cash in. And it looks," he said pessimistically, "as if our time to do so has come." * * * * * They ceased talking. Time passed cheerlessly. Finally both of them fell into a heavy slumber from which they were aroused by the sudden flashing in their eyes of a bright light, bright only in comparison with the former intense darkness. "What's that!" cried Ward, startled. "S-sh," said a soft voice warningly, and when their eyes became accustomed to the illumination, they were amazed to perceive the slender form of a young girl carrying a torch. She was marvelously lovely to look at, with her blue-black hair brushed straight back from a low, broad forehead and her smooth skin as dark as that of an Egyptian. Nor was she dressed unlike pictures Miles had seen of people of ancient Egypt. The embroidered plates covering the small breasts shone and glittered; bracelets and bangles flashed on bare arms and shapely ankles; while from the waist to below the knees was a skirt of rich material. On the small feet were sandals of intricate design. Besides the torch, the girl carried a slim, gleaming knife, and for a moment the adventurers were guilty of imagining she had come to slay them where they lay. But her manner quickly dispelled their fear. Sinking on her knees beside them, she said, "Do not be afraid; Ah-eeda will not harm you." * * * * *
