Robert Silverberg - Come Into My Brain

Dane Harrell held the thought-helmet tightly between his hands, and, before putting it on, glanced over at the bound, writhing alien sitting opposite him. The alien snarled defiantly at him.

Youre sure you want to go through with this? asked Dr. Phelps.

Harrell nodded. I volunteered, didnt I? I said Id take a look inside this buzzards brain, and Im going to do it. If I dont come up in half an hour, come get me.

Right.

Harrell slipped the cool bulk of the thought-helmet over his head and signalled to the scientist, who pulled the actuator switch. Harrell shuddered as psionic current surged through him; he stiffened, wriggled, and felt himself glide out of his body, hover incorporeally in the air between his now soulless shell and the alien bound opposite.

Remember, you volunteered, he told himself.

He hung for a moment outside the aliens skull; then he drifted downward and in. He had entered the aliens mind. Whether he would emerge alive, and with the troop-deployment datawell, that was another matter entirely.

The patrol-ships of the Terran outpost on Planetoid 113 had discovered the alien scout a week before. The Dimellian spy was lurking about the outermost reaches of the Terran safety zone when he was caught.

It wasnt often that Earth captured a Dimellian alive, and so the Outpost resolved to comb as much information from the alien as possible. The Earth-Dimell war was four years old; neither side had succeeded in scoring a decisive victory over the other. It was believed that Dimell was massing its fleets for an all-out attack on Earth itself; confirmation of this from the captured scout would make Terran defensive tactics considerably more sound.

But the Dimellian resisted all forms of brainwashing, until Phelps, the Base Psych-man, came forth with the experimental thought-helmet. Volunteers were requested; Harrell spoke up first. Now, wearing the thought-helmet, he plunged deep into the unknown areas of the Dimellians mind, hoping to emerge with high-order military secrets.

His first impression was of thick grey murkso thick it could be cut. Using a swimming motion, Harrell drifted downward, toward the light in the distance. It was a long way down; he floated, eerily, in free-fall.

Finally he touched ground. It yielded under him spongily, but it was solid. He looked around. The place was alien: coarse crumbly red soil, giant spike-leaved trees that shot up hundreds of feet overhead, brutal-looking birds squawking and chattering in the low branches.

It looked just like the tridim solidos of Dimell he had seen. Well, why not? Why shouldnt the inside of a mans mindor an aliens, for that matter, resemble his home world?

Cautiously, Harrell started to walk. Mountains rose in the dim distance, and he could see, glittering on a mountaintop far beyond him, the white bulk of an armored castle. Of course! His imaginative mind realized at once that there was where the Dimellian guarded the precious secrets; up there, on the mountain, was his goal.

He started to walk.

Low-hanging vines obscured his way; he conjured up a machete and cut them down. The weapon felt firm and real in his handbut he paused to realize that not even the hand was real; all this was but an imaginative projection.

The castle was further away than he had thought, he saw, after he had walked for perhaps fifteen minutes. There was no telling duration inside the aliens skull, either. Or distance. The castle seemed just as distant now as when he had begun, and his fifteen-minute journey through the jungle had tired him.

Suddenly demonic laughter sounded up ahead in the jungle. Harsh, ugly laughter.

And the Dimellian appeared, slashing his way through the vines with swashbuckling abandon.

Get out of my mind, Earthman!

The Dimellian was larger than life, and twice as ugly. It was an idealized, self-glorified mental image Harrell faced.

The captured Dimellian was about five feet tall, thick-shouldered, with sturdy, corded arms and supplementary tentacles sprouting from its shoulders; its skin was green and leathery, dotted with toad-like warts.

Harrell now saw a creature close to nine feet tall, swaggering, with a mighty barrel of a chest and a huge broadsword clutched in one of its arms. The tentacles writhed purposefully.

You know why Im here, alien. I want to know certain facts. And Im not getting out of your mind until Ive wrung them from you.

The aliens lipless mouth curved upward in a bleak smile. Big words, little Earthman. But first youll have to vanquish me.

And the Dimellian stepped forward.

Harrell met the downcrashing blow of the aliens broadsword fully; the shock of impact sent numbing shivers up his arm as far as his shoulder, but he held on and turned aside the blow. It wasnt fair; the Dimellian had a vaster reach than he could ever hope for

No! He saw there was no reason why he couldnt control the size of his own mental image. Instantly he was ten feet high, and advancing remorselessly toward the alien.

Swords clashed clangorously; the forest-birds screamed. Harrell drove the alien backback

And the Dimellian was eleven feet high.

We can keep this up forever, Harrell said. Getting larger and larger. This is only a mental conflict. He shot up until he again towered a foot above the aliens head. He swung downward twohandedly with the machete

The alien vanished.

And reappeared five feet to the right, grinning evilly. Enough of this foolishness, Earthman. Physical conflict will be endless stalemate, since were only mental projections, both of us. Youre beaten; theres no possible way you can defeat me, or I defeat you. Dont waste your time and mine. Get out of my mind!

Harrell shook his head doggedly. Im in here to do a job, and Im not leaving until Ive done it. He sprang forward, sword high, and thrust down at the grinning Dimellian.

Again the Dimellian sidestepped. Harrells sword cut air.

Dont tire yourself out, Earthman, the alien said mockingly, and vanished.

Harrell stood alone in the heart of the steaming jungle, leaning on his sword. Maybe they were only mental projections, he thought, but a mental projection could still get thoroughly drenched with its own mental sweat.

The castle still gleamed enigmatically on the distant mountain. He couldnt get there by walkingat least, it hadnt seemed to draw any nearer during his jaunt through the jungle. And hand-to-hand combat with the alien was fruitless, it appeared. A fight in which both participants could change size at will, vanish, reappear, and do other such things was as pointless as a game of poker with every card wild.

But there had to be a way. Mental attack? Perhaps that would crumble the aliens defenses.

He sent out a beam of thought, directed up at the castle. Can you hear me, alien?

Mental laughter echoed mockingly back. Of course, Earthman. What troubles you?

Harrell made no reply. He stood silently, concentrating, marshalling his powers. Then he hurled a bolt of mental energy with all his strength toward the mocking voice.

The jungle shuddered as it struck home. The ground lurched wildly, like an animals back; trees tumbled, the sky bent. Harrell saw he had scored a hit; the aliens concentration had wavered, distorting the scenery.

But there was quick recovery. Again the mocking laughter. Harrell knew that the alien had shrugged off the blow.

And then the counterblow.

It caught Harrell unawares and sent him spinning back a dozen feet, to land in a tangled heap beneath a dangling nest of vines. His head rocked, seemed ready to split apart. He sensed the alien readying a second offensive drive, and set up counterscreens.

This time he was ready. He diverted the attack easily, and shook his head to clear it. The score was even: one stunning blow apiece. But he had recovered, and so had the alien.
