"Yes, it is I, Mal Shaff," boomed the other. "Remember, Ouglat, the day you destroyed me and my plane. I have returned to wreak my vengeance. I have solved a mystery you have never guessed and I have come back. You did not imagine you were attacking me again when you sent your minions to that other plane to feed upon the beings there. It was I you were attacking, fool, and I am here to kill you." Ouglat leaped and the thing that had been Henry Woods, newspaperman, and ninety-eight other men, but was now Mal Shaff of the fourth dimension, leaped to meet him. Mal Shaff felt the force of Ouglat, felt the sharp pain of a hammering fist, and lashed out with those horrible arms of his to smash at the leering face of his antagonist. He felt his fists strike solid flesh, felt the bones creak and tremble beneath his blow. His nostrils were filled with the terrible stench of the other's foul breath and his filthy body. He teetered on his gnarled legs and side-stepped a vicious kick and then stepped in to gouge with straightened thumb at the other's eye. The thumb went true and Ouglat howled in pain. Mal Shaff leaped back as his opponent charged head down, and his knotted fist beat a thunderous tattoo as the misshapen beast closed in. He felt clawing fingers seeking his throat, felt ghastly nails ripping at his shoulders. In desperation he struck blindly, and Ouglat reeled away. With a quick stride he shortened the distance between them and struck Ouglat a hard blow squarely on his slavering mouth. Pressing hard upon the reeling figure, he swung his fists like sledge-hammers, and Ouglat stumbled, falling in a heap on the sand. Mal Shaff leaped upon the fallen foe and kicked him with his taloned feet, ripping him wickedly. There was no thought of fair play, no faintest glimmer of mercy. This was a battle to the death: there could be no quarter. * * * * * The fallen monster howled, but his voice cut short as his foul mouth, with its razor-edged fangs, closed on the other's body. His talons, seeking a hold, clawed deep. Mal Shaff, his brain a screaming maelstrom of weird emotions, aimed pile-driver blows at the enemy, clawed and ripped. Together the two rolled, locked tight in titanic battle, on the sandy plain and a great cloud of heavy dust marked where they struggled. In desperation Ouglat put every ounce of his strength into a heave that broke the other's grip and flung him away. The two monstrosities surged to their feet, their eyes red with hate, glaring through the dust cloud at one another. Slowly Ouglat's hand stole to a black, wicked cylinder that hung on a belt at his waist. His fingers closed upon it and he drew the weapon. As he leveled it at Mal Shaff, his lips curled back and his features distorted into something that was not pleasant to see.
