In his right hand, moving toward his girdle, he had suddenly felt movement where movement should not be. His voice died away as he stood and glared at nothing; and inside his clenched right hand he felt the quivering of _change_, of _motion_, of _life_. He no longer held a smooth shining sphere in his fingers. And he dared not look; his tongue clove to the roof of his mouth, and he could not open his hand. His astonished warriors saw Yar Afzal's eyes distend, the color ebb from his face. Then suddenly a bellow of agony burst from his bearded lips; he swayed and fell as if struck by lightning, his right arm tossed out in front of him. Face down he lay, and from between his opening fingers crawled a spider--a hideous, black, hairy-legged monster whose body shone like black jade. The men yelled and gave back suddenly, and the creature scuttled into a crevice of the rocks and disappeared. The warriors started up, glaring wildly, and a voice rose above their clamor, a far-carrying voice of command which came from none knew where. Afterward each man there--who still lived--denied that he had shouted, but all there heard it. 'Yar Afzal is dead! Kill the outlander!' That shout focused their whirling minds as one. Doubt, bewilderment and fear vanished in the uproaring surge of the blood-lust. A furious yell rent the skies as the tribesmen responded instantly to the suggestion. They came headlong across the open space, cloaks flapping, eyes blazing, knives lifted. Conan's action was as quick as theirs. As the voice shouted he sprang for the hut door. But they were closer to him than he was to the door, and with one foot on the sill he had to wheel and parry the swipe of a yard-long blade. He split the man's skull--ducked another swinging knife and gutted the wielder--felled a man with his left fist and stabbed another in the belly--and heaved back mightily against the closed door with his shoulders. Hacking blades were nicking chips out of the jambs about his ears, but the door flew open under the impact of his shoulders, and he went stumbling backward into the room. A bearded tribesman, thrusting with all his fury as Conan sprang back, overreached and pitched head-first through the doorway. Conan stopped, grasped the slack of his garments and hauled him clear, and slammed the door in the faces of the men who came surging into it. Bones snapped under the impact, and the next instant Conan slammed the bolts into place and whirled with desperate haste to meet the man who sprang from the floor and tore into action like a madman.
