The Night of the Long Knives ♦ By Fritz Leiber

I was one hundred miles from Nowhere ― and I mean that literally ― when I spotted this girl out of the corner of my eye. I’d been keeping an extra lookout because I still expected the other undead bugger left over from the murder party at Nowhere to be stalking me.
Welcome to Deathland, a postapocalyptic nuclear desert where kill or be killed is the law of the land. The radiation-damaged survivors of this ravaged region are consumed by the urge to murder each other, making partnership of any sort a lethal risk. But when two drifters forge an uneasy truce, the possibility of a new life beckons. "I was one hundred miles from Nowhere—and I mean that literally—when I spotted this girl out of the corner of my eye. I'd been keeping an extra lookout because I still expected the other undead bugger left over from the murder party at Nowhere to be stalking me." In a Post apocalyptic world, the few people left must be strong. And must not hesitate to kill. Of course, killing another Deathlander was one of the chief pleasures and urges of all the solitary wanders in this vast wasteland. Kill and kill again. But this other was a girl and that brought up the second great urge: sex. Which was it to be today? Perhaps both? And who would walk away afterward?
