heap of broken and whitening bones. A creature of metal, twice the height of Asir, he had obviously been designed to kill. Tri-fingered hands with gleaming talons, and a monstrous head shaped like a Marswolf, with long silver fangs. Why should a metal-creature have fangs, unless he had been built to kill? The behemoth slept in a crouch, waiting for the intruders. He tugged the girl through the stairwell door. A voice droned out of nowhere: "If you have come to plunder, go back!" He stiffened, looking around. The girl whimpered. "Stay here by the stairs," he told her, and pushed her firmly back through the door. Asir started slowly toward the room where Big Joe waited. Beyond the room he could see another door, and the monster's job was apparently to keep intruders back from the inner vaults where, according to the ritual chants, the Blaze of the Winds could be kindled. Halfway along the corridor, the voice called out again, beginning a kind of sing-song chant: "Big Joe will kill you, Big Joe will kill you, Big Joe will kill you——" He turned slowly, searching for the speaker. But the voice seemed to come from a black disk on the wall. The talking-machines perhaps, as mentioned somewhere in the ritual. A few paces from the entrance to the room, the voice fell silent. He stopped at the door, staring in at the monster. Then he took a deep breath and began chanting the twenty-four numbers in a loud but quavering voice. Big Joe remained in his motionless crouch. Nothing happened. He stepped through the doorway. Big Joe emitted a deafening roar, straightened with a metallic groan, and lumbered toward him, taloned hands extended and eyes blazing furiously. Asir shrieked and ran for his life. Then he saw Mara lying sprawled in the stairway entrance. She had fainted. Blocking an impulse to leap over her and flee alone, he stopped to lift her. But suddenly he realized that there was no pursuit. He looked back. Big Joe had returned to his former position, and he appeared to be asleep again. Puzzled, Asir stepped back into the corridor. "If you have come to plunder, go back!" He moved gingerly ahead again.
