There was a hissing order, and two figures from the corner sprang forward to seize the flyer with long clinging fingers. Their strength he had overestimated, for a violent throw of his body twisted him free, and his outstretched hands sent the two sprawling across the room. Their leader took one quick step forward, then paused as if hesitating to meet this young adversary. "Do go easy," Professor Sykes was imploring. "We do not know where we are nor who they are, but we must do nothing to antagonize them." McGuire had reacted from his hilarious seizure with an emotional swing to the opposite extreme. "I'll break their damn necks," he growled, "if they get rough with me." And his narrow eyes exchanged glare for glare with those in the face like blood and ashes before him. The cold cat eyes held steadily upon him while the scarlet figure retreated. A louder call, shrill and vibrant, came from the thin lips, and a swarm of bodies in dull red were scrambling into the room to mass about their scarlet leader. Above and behind them the face under its brilliant turban and golden clasp was glaring in triumph. The tall figures crouched, grotesque and awkward; their long arms and hands with grasping, tendril-like fingers were ready. McGuire waited for the sharp hissing order that would throw these things upon him, and he met the attack when it came with his own shoulders dropped to the fighter's pose, head drawn in close and both fists swinging free. There were lean fingers clutching at his throat, a press of blood-red bodies thick about him, and a clustering of faces where color blotched and flowed. The thud of fists in blows that started from the floor was new to these lean creatures that clawed and clung like cats. But they trampled on those who went down before the flyer's blows and stood upon them to spring at his head; they crowded in in overwhelming numbers while their red hands tore and twined about his face. * * * * * It was no place now for long swings; McGuire twisted his body and threw his weight into quick short jabs at the faces before him. He was clear for an instant and swung his heavy boot at something that clung to one leg; then met with a rain of hooks and short punches the faces that closed in again. He saw in that instant a wild whirl of bodies where the stocky figure of Professor Sykes was smothered beneath his taller antagonists. But the professor, if he was forgetting the science of the laboratory, was remembering that of the squared circle--and the battle was not entirely one sided. McGuire was free; the blood was trickling down his face from innumerable cuts where sharp-nailed fingers had sunk deep. He wiped the red stream from his eyes and threw himself at the weaving mass of bodies that eddied about Sykes in frantic struggle across the room.
