A beautiful woman always looks most beautiful when she is just a little angry. Redgrave had never seen Zaidie look quite so lovely as she did just then. The Martian, whose ancestors had for generations forgotten what human emotion was like, only saw in her anger a miracle which made her a thousand times more beautiful than before, and as he looked upon her glowing cheeks and gleaming eyes some instinct insensibly transmitted through many generations awoke to sudden life in some unused corner of his brain. His pale clear eyes lit up with something like a glow of human passion. The pink spots under his eyes spread downwards over his cheeks. Some half-articulate sounds came from between his thin lips. Then they were drawn back and showed his smooth, toothless gums. He took a couple of long, swift strides towards her, and then bent forward, towering over her with long, outstretched arms, huge, hideous, and half-human. Zaidie sprang backwards as he came towards her, her right hand went up, and, just as Redgrave levelled his revolver, and Murgatroyd, true to the old Berserk instinct, took a rifle by the barrel and swung the stock above his head, Zaidie pulled her trigger. The bullet cut a clean hole through the smooth, hairless skull of the Martian. A dark, red spot came just between his eyes, his huge frame shrank together and collapsed in a heap on the deck. "Oh, I've killed him! God forgive me, killed a man!" she whispered, as her hand fell to her side, and the revolver dropped from her fingers. "But, Lenox, do you really think it was a man?" "That thing a man!" he replied between his clenched teeth. "He wanted you, and spoke English of a sort, so there was something human about him, but anyhow he's better dead. Here, Andrew, open that door again and help me to heave this thing overboard. Then I think we'd better be off before we have the rest of the fleet with their poison guns round us. Zaidie, I think you'd better go to your room for the present. Take a nip of cognac and then lie down, and mind you keep the door tight shut. There's no telling what these animals might do if they had a chance, and just now it's my business and Andrew's to see that they don't." Though she would much rather have remained on deck to see anything more that might happen, she saw that he was really in earnest, and so like a wise wife who commands by obeying, she obeyed, and went below. Then the dead body of the Martian was tumbled out of the side door. The windows through which the guns had been fired were hermetically closed, and a few minutes later the _Astronef_ vanished from the surface of Mars, to remain a memory and a marvel to the dwindling generations of the worn-out world which is as this may be in the far-off days that are to come.
