"For God's sake, Eve!" implored Northwood. "Wait! Wait!" "No! She shall die, too. You love her!" Icy, cruel eyes cut into him, and a new-fleshed hand tried to push him aside. The door was straining open. A beloved voice shrieked. "John!" Eve and Northwood both leaped for the lever. Under her tender white flesh she was as strong as a man. In the midst of the struggle, her red, humid lips approached his--closer. Closer. Their merest pressure would thrust him into Future Time, where the laboratory and all it contained would be but a shadow, and where he would be helpless to interfere with her terrible will. He saw the door open and Adam stride into the room. Behind him, lying prone in the hall where she had probably fainted, was Athalia. In a mad burst of strength he touched the lever together with Eve. The projector, belching forth its stinking breath of corruption swung in a mad arc over the ceiling, over the walls--and then straight at Adam. Then, quicker than thought, came the accident. Eve, attempting to throw Northwood off, tripped, fell half over the machine, and, with a short scream of despair, dropped into the black path of destruction. * * * * * Northwood paused, horrified. The Death Ray was pointed at an inner wall of the room, which, even as he looked, crumbled and disappeared, bringing down upon him dust more foul than any obscenity the bowels of the earth might yield. In an instant the black cone ate through the outer parts of the building, where crashing stone and screams that were more horrible because of their shortness followed the ruin that swept far into the fair reaches of the valley. The paralyzing odor of decay took his breath, numbed his muscles, until, of all that huge building, the wall behind him and one small section of the room by the doorway alone remained whole. He was trying to nerve himself to reach for the lever close to that quiet formless thing still partly draped over the machine, when a faint sound in the door electrified him. At first, he dared not look, but his own name, spoken almost in a gasp, gave him courage. Athalia lay on the floor, apparently untouched. He jerked the lever violently before running to her, exultant with the knowledge that his own efforts to keep the ray from the door had saved her. "And you're not hurt!" He gathered her close. "John! I saw it get Adam." She pointed to a new mound of mouldy clothes on the floor. "Oh, it is hideous for me to be so glad, but he was going to destroy everything and everyone except me. He made the ray projector for that one purpose." Northwood looked over the pile of putrid ruins which a few minutes ago had been a building. There was not a wall left intact. "His intention is accomplished, Athalia," he said sadly. "Let's get out before more stones fall." * * * * *
