"No, no, Euphemia," Patrick protested anxiously. "It's hell out there, believe me. I wouldn't lie to you about it." "Wouldn't lie to me!" she mocked. "Are you afraid, too?" With a sudden pull, she jerked open the window and stood before the blank green-tinged oblong of darkness that seemed to press into the room like a menacing, heavy, wind-urged curtain. At that Hank cried out a shocked, pleading, "Effie!" She ignored him. "I can't be cooped up here any longer," she said. "And I won't, now that I know. I'm going to the garden." Both men sprang at her, but they were too late. She leaped lightly to the sill, and by the time they had flung themselves against it, her footsteps were already hurrying off into the darkness. "Effie, come back! Come back!" Hank shouted after her desperately, no longer thinking to cringe from the man beside him, or how the gun was pointed. "I love you, Effie. Come back!" Patrick added his voice. "Come back, Euphemia. You'll be safe if you come back right away. Come back to your home." No answer to that at all. They both strained their eyes through the greenish murk. They could barely make out a shadowy figure about half a block down the near-black canyon of the dismal, dust-blown street, into which the greenish moonlight hardly reached. It seemed to them that the figure was scooping something up from the pavement and letting it sift down along its arms and over its bosom. "Go out and get her, man," Patrick urged the other. "For if I go out for her, I warn you I won't bring her back. She said something about having stood the dust better than most, and that's enough for me." But Hank, chained by his painfully learned habits and by something else, could not move. And then a ghostly voice came whispering down the street, chanting, "Fire can hurt me, or water, or the weight of Earth. But the dust is my friend." Patrick spared the other man one more look. Then, without a word, he vaulted up and ran off. Hank stood there. After perhaps a half minute he remembered to close his mouth when he inhaled. Finally he was sure the street was empty. As he started to close the window, there was a little _mew_. He picked up the cat and gently put it outside. Then he did close the window, and the shutters, and bolted them, and took up the Geiger counter, and mechanically began to count himself. --FRITZ LEIBER Transcriber's Note: This etext was produced from _Galaxy Science Fiction_ April 1952.
