Then he saw the cave mouth, a wide, low arch of darkness just above him on the slope. It was about a meter and a half high at its central point. With a shower of crossbow bolts raining around him, Dalt quickly ducked inside.
It wasn't much of a cave. In the dark and dampness Dalt soon found that it rapidly narrowed to a tunnel too slender for his shoulders to pass. There was nothing else for him to do but stay as far back as possible and hope for the best... which wasn't much no matter how he looked at it. If his pursuers didn't feel like corning in to drag him out, they could just sit back and fill the cave with bolts. Sooner or later one would have to strike him. Dalt peered out the opening to see which it would be.
But his five pursuers were doing nothing. They sat astride their mounts and stared dumbly at the cave mouth. One of the party unstrung his crossbow and began to strap it to his back. Dalt had no time to wonder at their behavior, for in that instant he realized he had made a fatal error. He was in a cave on Kwashi, and there was hardly a cave on Kwashi that didn't house a colony of alarets.
He jumped into a crouch and sprinted for the outside. He'd gladly take his chances against crossbows rather than alarets any day. But a warm furry oval fell from the cave ceiling and landed on his head as he began to move. As his ears roared and his vision turned orange and green and yellow, Steven Dalt screamed in agony and fell to the cave floor.
Hearing that scream, the five Tependian scouts shook their heads and turned and rode away.
It was dark when he awoke and he was cold and alone ... and alive. That last part surprised him when he remembered his situation, and he lost no time in crawling out of the cave and into the clean air under the open stars. Hesitantly, he reached up and peeled from his scalp the shrunken, desiccated remains of one dead alaret. He marveled at the thing in his hand. Nowhere in the history of Kwashi, neither in the records of its long-extinct native race nor in the memory of anyone in its degenerated splinter colony, had there ever been mention of someone surviving the attack of an alaret.
The original splinter colonists had found artifacts of an ancient native race soon after their arrival. The culture had reached preindustrial levels before it was unaccountably wiped out; a natural cataclysm of some sort was given the blame. But among the artifacts were found some samples of symbolic writing, and one of these samples—evidently aimed at the children of the race—strongly warned against entering any cave. It seemed that a creature described as the killing-thing-on-the-ceilings-of-caves would attack anything that entered. The writing warned: "Of every thousand struck down, nine hundred and ninety-nine will die."
William Alaret, a settler with some zoological training, had heard the translation and decided to find out just what it was all about. He went into the first cave he could find and emerged seconds later, screaming and clawing at the furry little thing on his head. He became the first of many fatalities attributed to the killing-thing-on-the-ceilings-of-caves, which were named "alarets" in his honor.
Dalt threw the alaret husk aside, got his bearings, and headed for his hidden shuttlecraft. He anticipated little trouble this time. No scouting party, if any were abroad at this hour, would be likely to spot him, and Kwashi had few large carnivores.
The ship was as he had left it. He lifted slowly to fifty thousand meters and then cut in the orbital thrust. That was when he first heard the voice.
("Hello, Steve.")
If it hadn't been for the G-forces against him at that moment, Dalt would have leaped out of his chair in surprise.
("This pressure is quite uncomfortable, isn't it?") the voice said, and Dalt realized that it was coming from inside his head. The thrust automatically cut off as orbit was reached and his stomach gave its familiar free-fall lurch.
("Ah! This is much better.")
"What's going on?" Dalt cried aloud as he glanced frantically about. "Is this someone's idea of a joke?"
("No joke, Steve. I'm what's left of the alaret that landed on your head back in that cave. You're quite lucky, you know. Mutual death is a sure result—most of the time, at least—whenever a creature of high-level intelligence is a target for pairing.") I'm going mad! Dalt thought.
("No, you're not, at least not yet. But it is a possibility if you don't sit back and relax and accept what's happened to you.")
Dalt leaned back and rested his eyes on the growing metal cone that was the Star Ways Corporation mother-ship, on the forward viewer. The glowing signal on the console indicated that the bigger ship had him in traction and was reeling him in.
"Okay, then. Just what has happened to me?" He felt a little ridiculous speaking out loud in an empty cabin.
("Well, to put it in a nutshelclass="underline" You've got yourself a roommate, Steve. From now on, you and I will be sharing your body.")
"In other words, I've been invaded!"
("That's a loaded term, Steve, and not quite accurate. I'm not really taking anything from you except some of your privacy, and that shouldn't really matter since the two of us will be so intimately associated.")
"And just what gives you the right to invade my mind?" Dalt asked quickly, then added: "—and my privacy?"
("Nothing gives me the right to do so, but there are extenuating circumstances. You see, a few hours ago I was a furry, lichen-eating cave slug with no intelligence to speak of—")
"For a slug you have a pretty good command of the language!" Dalt interrupted.
("No better and no worse than yours, for I derive whatever intelligence I have from you. You see, we alarets, as you call us, invade the nervous system of any creature of sufficient size that comes near enough. It's an instinct with us. If the creature is a dog, then we wind up with the intelligence of a dog—that particular dog. If it's a human and if he survives, as you have done, the invading alaret finds himself possessing a very high degree of intelligence.")
"You used the word 'invade' yourself just then."
("Just an innocent slip, I assure you. I have no intention of taking over. That would be quite immoral.")
Dalt laughed grimly. "What would an ex-slug know about morality?"
("With the aid of your faculties I can reason now, can I not? And if I can reason, why can't I arrive at a moral code? This is your body and I am here only because of blind instinct. I have the ability to take control—not without a struggle, of course—but it would be immoral to attempt to do so. I couldn't vacate your mind if I wanted to, so you're stuck with me, Steve. Might as well make the best of it.")
"We'll see how 'stuck' I am when I get back to the ship," Dalt muttered. "But I'd like to know how you got into my brain."
("I'm not exactly sure of that myself. I know the path I followed to penetrate your skull—if you had the anatomical vocabulary I could describe it to you, but my vocabulary is your vocabulary and yours is very limited in that area.")
"What do you expect? I was educated in cultural studies, not medicine!"
("It's not important anyway. I remember almost nothing of my existence before entering your skull, for it wasn't until then that I first became truly aware.")
Dalt glanced at the console and straightened up in his seat. "Well, whatever you are, go away for now. I'm ready to dock and I don't want to be distracted."
("Gladly. You have a most fascinating organism and I have much exploring to do before I become fully acquainted with it. So long for now, Steve. It's nice knowing you.")
A thought drifted through Dalt's head: If I'm going nuts, at least I'm not doing it halfheartedly!
