Strange Highways

and store of knowledge to facilitate its conquest of the world. Teel Pleever, Jane Halliwell, and all the others would be horribly aware during their months of total enslavement: aware of the world around them, aware of the monstrous acts they were committing, and aware of Seed nesting within them.
     It walked its two hosts up the porch steps and used Pleever to knock loudly on the front door.
     When no man, woman, or child on earth remained free, Seed would advance to the next stage, the Day of Release, abruptly allowing its hosts to resume control of their bodies, though in each of them would remain an aspect of the puppetmaster, always gazing out through their eyes and monitoring their thoughts. By the Day of Release, of course, at least half of the hosts would be insane. Others, having held on to sanity in hope of eventual release from torment, would be rocked by the realization that even after regaining control of themselves, they must endure the cold, parasitic presence of the intruder forever; they too would then go slowly mad. That was what always happened. A smaller group would inevitably seek solace in religion, forming a socially disruptive cult that would worship Seed. And the smallest group of all, the tough ones, would remain sane and either adapt to Seed's presence or seek ways to evict it, a crusade that would not prove successful.
     Seed rapped on the door again. Perhaps no one was at home.
     "Coming, coming," a man called from inside.
     Ah, good.
     Following the Day of Release, the fate of this sorry world would conform to the usual pattern: mass suicides, millions of homicides committed by psychopaths, complete and bloody social collapse, and an irreversible slide into anarchy, barbarism.
     Chaos.
     Creating chaos, spreading chaos, nurturing chaos, observing and relishing chaos were Seed's only purposes. The thing had been born in the genesis explosion at the start of time. Before that, it had been part of the supreme chaos of supercondensed matter in the time before time began. When that great undifferentiated ball of genesis matter exploded, the universe was formed; unprecedented order arose in the void, but Seed was not part of that order. It was a remnant of precreation chaos; protected by an invincible shell, it drifted forth into the blossoming galaxies, in the service of entropy.
     A man opened the door. He was leaning on a cane.
     "Mr. Pleever, isn't it?" he said.
     From Jane Halliwell, Seed extruded black tendrils.
     The man with the cane cried out as he was seized.
     A blue-spotted black stalk burst from Jane Halliwell's mouth, pierced the crippled man's chest, and in seconds Seed had its third host: Jack Caswell.
     The man's legs had been so badly damaged in an accident that he wore metal braces. Because Seed did not want to be slowed down by a crippled host, it healed Caswell's body and shucked off the braces.
     Drawing upon Caswell's knowledge, Seed discovered that no one else was at home. It also learned that Caswell's wife taught at an elementary school and that this school, containing at least a hundred and sixty children and their teachers, was only three miles away. Rather than stop at every dwelling on the road into Pineridge, Seed could more effectively go to the school, seize control of everyone, and then spread out with all those hosts in every direction.
     Jack Caswell, though imprisoned by Seed, was privy to his alien master's thoughts, because they shared the same cerebral tissue and neural pathways. Upon realizing that the school was to be attacked, Caswell's trapped mind squirmed violently, trying to slip free of its shackles.
     Seed was surprised by the vigor and persistence with which the man resisted. With Pleever and the Halliwell woman, it had noticed that human beings - as they called themselves - possessed a far more powerful will than any species with which it had previously enjoyed contact. Now Caswell proved to have a considerably stronger will than either Pleever or Halliwell. Here was a species that obviously struggled relentlessly to create order out of chaos, that tried to make sense of existence, and that was determined to impose order on the natural world by the sheer power of its will. Seed was going to take special pleasure in leading humanity into chaos, degeneration, and ultimately into devolution.
