And then there came an ominous grinding sound from underneath the very seat occupied by the invisible fugitives. A puff of dense black smoke followed and Ulana coughed spasmodically, uncontrollably. They were coming now, two of the green-bronze ones, to investigate. There was no escape from this narrow space. And--Ulana was gone! She had slipped from his grasp in the coughing fit and he could not find her with his wildly searching hands. Another betraying cough over there. The green-bronze ones were between them. He saw one of them draw back in amazement, then clench his fingers and twist. The ripping sound of torn material followed and the girl's head and startled face appeared: floating there, unsupported, her body and limbs as yet invisible. But they'd found her; she was lost! CHAPTER IX _Ianito_ Quickly stripping the protecting cloak from her body, the green-bronze one held the struggling girl gingerly but with a grip of iron. His eyes bulged from their sockets, and the other guard staggered backward with hands outstretched as if to ward off an evil spell that might be cast by this supernatural visitant. Blaine thrust his arm through the folds of his coat, ray pistol in hand. A crazy laugh forced itself to his lips at sight of the detached member, stretched there, tensed, drifting in mid-air. The pistol prodded Ulana's captor viciously. "Hands off of her!" the voice behind the lone arm was snarling. "Hands off, or I fire!" The girl slipped to the floor in a heap as the amazed guard loosed his grip. And, in the same instant, the blue flame spurted. He had not intended to press the release; it was useless anyway to battle the entire outfit. But the blood lust was upon him and a savage joy in the destruction of this beast who had dared lay hands on Ulana impelled him to turn on the other. Blindly he swung, clubbing the pistol and beating in the ghastly face that wobbled there upon the spineless, superstition-bound body. Others were coming then, hundreds of them it seemed. The pale face of Dantor appeared for an instant in the background, through the red haze that was blinding him. He only knew he was fighting desperately, viciously, and against impossible odds. The satisfying crunch of his left fist against a leering green-bronze face was followed by an excruciating pain as one of his knuckles was driven back. Hardly knowing he had pressed the release of the ray, he was mildly astonished to see that two of the guards were enveloped in the blue vapor. Scintillant tiny sunbursts within the blue. Two less of those devils! His pistol was empty and he flung it into a grinning face; he saw the blood spurt and the face change shape, crushed beyond human resemblance. He was down then, gasping for breath against the floor plates. The weight upon him was enormous; crushing. If only they'd quit squirming so ... and pounding ... reminded him of his old football days ... some scrimmage! Abruptly came the blankness of insensibility.
