"I did something worthwhile—in my new world—didn't I? That's—good—I guess I'm—glad—" A gush of blood from his mouth choked him. Tara was down beside him, her hand on his. He was trying to smile at her as the light went out of his eyes and he died. "Oh, John—" I was aware that the shouts from the oncoming mob were much louder now. Rocks were clattering into the arcade opening. "Tara—we've got to—" It seemed too late. In the opening three or four of the mob appeared, brandishing their weapons. My gun spat its sizzling bolt. One of the men screamed, leaped and fell. The others scattered as I ran forward. On the ledge, with Tara behind me, I stared down at the advancing mob. The first milling ranks of it were hardly more than fifty feet from the top. My bolt hissed again; another man fell.... "John—oh, please—my people—" Tara's hand checked me. But I could not be sure, if we tried to retreat, but that the frenzied throng would be able to overtake us. Then with sudden thought I adjusted the gun to a spreading heat-beam. The wave of heat leaped down—again and again—heat diffused over a wide area, not intense enough to kill. But before it the leaders of the Zurians staggered back, terrified, with their hands before their faces. The mob behind them wavered. Down at the bottom of the slope, others were pressing upward. In a moment it was a milling, scrambling crowd with panic spreading. And then the wavering ranks of it began rolling back until it was a rout.... "Tara, come—hurry—they'll be after us in a moment—" White-faced, with sorrow in her eyes mingled with wonderment, as though still she could not believe this catastrophe, she nodded. She led me as we ran, plunging down into the maze of tortuous corridors. Breathless, panting, we ran; rested a moment in a dim, glowing passage—and ran again. "Oh, John—" "Don't talk, Tara—keep going—" It seemed that we could hear muffled shouts far behind us. But presently we outdistanced them, and then at last, after an eternity, we came safely out onto the upper surface. It was night; glittering starlight on this doomed little world, heading for the heat of our giant sun.
