"There's a planet near Ades--Thom Four. Four years ago its matter-transmitter ceased to operate. The Galaxy's going to pot anyhow. Nothing new about that! But we just learned the real reason. The real reason was that four years ago fighting-beams killed men and left women unharmed. "Every man on Thom Four died as the planet rotated. The beams came from space. Every man and every boy and every male baby died! There were only girls and women left." He added curtly, "There were half a billion people on Thom Four!" Kim stiffened. Dona, beside him, drew closer. "Every man killed!" said Kim. "What--" The Mayor of Steadheim swore angrily. "Half the population! On Ades we're nine-tenths men! Women don't run to revolt or crime. There'd not be much left on Ades if those beams swept us! But I'm talking about Thom Four. The men died. All of them. So many that the women couldn't bury them all. "One instant, the planet was going about its business as usual. The next, every man was dead, his heart burst and blood running from his nostrils. Lying in the streets, toppled in the baths and eating-halls, crumpled beside the machines. "Boys in the schools dropped at their desks. Babes in arms, with their mothers shrieking at the sight! Only women left. A world of women! Cities and continents filled with dead men and women going mad with grief!" Kim felt Dona's hand fumbling for his. She held it fast. "Go on!" said Kim. "When they thought to go to the matter-transmitter and ask for help from other planets the matter-transmitter was smashed. They didn't go at first. They couldn't believe it. They called from city to city before they realized theirs was a manless world. Then, when they'd have told the men of another planet what had happened--they couldn't. "For four years there was not one man or boy on the planet Thom Four. Only women. The old ones grew older. The girls grew up. Some couldn't remember ever seeing a man. No communication with other worlds. Then, one day, there was a new matter-transmitter in the place of the smashed one. Men came out of it. The women crowded about them. "The men were very friendly. They were from Sinab Two. Their employer had sent them to colonize. There were a thousand women to every man--ten thousand! Some of the women realized what had been done. They'd have killed the newcomers. But some women fell in love with them, of course! "In a matter of days every man had women ready to fight all other women who would harm him. Their own men were dead four years. What else could they do? More and more men colonists came. Presently things settled down. The men were happy enough. They'd no need to work with all the women about. "They established polygamy, naturally! Presently it was understood that Thom Four was part of the empire of Greater Sinab. So it was. What else? In a generation there'll be a new population, all its citizens descended from loyal subjects of the emperor.
