The Best Of Lester Del Rey Part 29

6.

Gra.s.s grew and flowers bloomed. Ants built nests and crickets chirped in the soft summer night. The seas swarmed with marine life of most kinds. And reptiles sunned themselves on rocks, or retired to their holes when the sunwas too hot. But on all Earth, no warmblooded animal could be found.

The Earth of man was without form and void. The cities were slag heaps from which radioactivity still radiated. No fires buftied on the hearthstones of the most isolated houses^ -The villages were usually burned, sometimes apparently by accident, but often as if they had been fired deliberately by their owners.

The Moon was a thing of glory over Lake Michigan. It was the only glorious thing for six hundred miles. Four returned winged rockets rested on a field hi Florida, but there was no sign of what had become of the men who rode down from the station in them. One winged craft stood forlornly outside Denver, and there was a scrawl in crayon inside its port that spelled the worst obscenity in the English language.

There was a library still standing in Phoenix, and the last newspaper had the dateline of the day when Sam had seen the lights brighten over the cities of Earth. There was no news beyond that of purely local importance. Most of the front page was occupied by a large box which advised readers that the government had taken over all radio communications during the crisis and would broadcast significant news on the hour. The paper was cooperating with the government in making such news available by broadcast only. The same box appeared in the nine preceding issues. Before that, the major news seemed to involve a political campaign in United South Africa.

Other scattered small libraries had differently named papers that were no different. Yet the only clue was in one of those libraries. It was a piece of paper resting under the finger bones of a skeleton that was scattered before bound copies of a technical journal. The paper was covered with doodles and stained in what might have been blood. But the words were legible: "Lesson for the day. a.s.sign to all students. Politics: They could not win and that is obvious. Chemistry: Their nerve gas was similar to one we tested in small quant.i.ties. It seemed safe. Yet when they dropped it over us in both Northern and Southern hemispheres, it did not settle out as the test batches had done. Practice: Such aerosols can be tested only in ma.s.sive quant.i.ties.

Medicine: Janice was in the shelter with me three I.

weeks, yet there was still enough in the air to make her die in the ecstasy of a theophany. Meteorology: The wind patterns have been known for years. In three weeks, they reach all the Earth. Psychology: I am mad. But my madness is that I am become only cold logic without a soul. Therefore, I must kill myself. Religion: Nothing matters. I am mad. G.o.d is-" That was all.

The creche was still the same, of course. Sam sat before the entrance, staring at the Moon that was rising over the horizon. It was a full Moon again, and there was beauty to it, even here. But he was only vaguely aware of that.

Below him, the great computer was busily integrating the ma.s.s of tiny details he had gathered together with all of the millions of facts it knew. That job took time, even for such a machine.

Now it called him over the radio frequencies, as he had ordered it to do earlier hi the day. He issued the formal command for it to go ahead.

"All data correlated," it announced. "None was found fully coherent with previous data. Degree of relevancy approaches zero. Data insufficient for conclusion."

He grunted to himself and put the machine back on stand-by. He had expected little else. He had known there was too little material for a logical conclusion.

But his own conclusion had been drawn already. Now he sat under the light of the Moon, staring up at the sky, and there was a coldness in his brain complex that seemed deeper than the reaches of s.p.a.ce.

They had come from somewhere out there, he thought bitterly. They had appearedmore than a century before and snooped and sniffed at Earth, only to leave.

Now they had come back, giving Earth only a week's warning as they approached.

They had struck all Earth with glowing bombs or radiation that ruined the cities of men. And when men had still survived, they resorted to a deadly mist of insanity. "They dropped it over us," the npie had said. And the wonderful race Sam had knoi#a'Bad died in madness, usually of some destructive kind.

There had not even been a purpose to it. The Invaders hadn't wanted the Earth for themselves. They had simply come and slaughtered, to depart as senselessly as they had departed before.

Sam beat his fists against his leg so that the metal clanged through the night. Then he lifted his other fist toward the stars and shook it.

It was wrong that they should get away. They had come with fire and pestilence, and they should be found and met with all that they had meted out to mankind. He had supposed that evil was something found only hi fiction. But now evil had come. It should be met as it was usually met in fiction. It should be wiped from the universe in a suffering as great as it had afflicted.

But such justice was apparently the one great lie of fiction.

He beat his fists against his legs again and shouted at the Moon, but there was no relief for what was in him.

Then his ears picked up a new sound and he stopped all motion to listen. It came again, weakly and from far away.

"Help!"

He shouted back audibly and by radio and was on his feet, running toward the sound. His feet crashed through the brush and he leaped over the rubble, making no effort to find the easy path. As he stopped to listen again, he heard the sound, directly ahead, but even weaker. A minute later he almost stumbled over the caller.

It was a robot. Once it had been slim and neat, covered with black enamel. Now it was bent and the bare metal was exposed. But it was still a Mark Three. It lay without motion, only a whisper coming from its speaker.

Sam felt disappointment strike through all his brain complex, but he bent over the p.r.o.ne figure, testing quickly. The trouble was power failure, he saw at once. He ripped a spare battery from the pack he had been carrying on his search and slammed it quickly into place, replacing the corroded one that had been there.

The little robot sat up and began trying to get to its feet. Sam reached out a helping hand, staring down at the worn, battered legs that seemed beyond any hope of functioning.

"You need help," he admitted. "You need a whole new body. Well, there are a thousand new ones below waiting for you. What's your number?"

It had to be one of the robots from the Moon. There had never been any others permitted on Earth.

The robot teetered for a moment, then seemed to gain some mastery over its legs. "They called me Joe. Thank you, Sam. I was afraid I couldn't reach you.

I heard your radio signal from here almost a month ago, but it was such a long way. And my radio transmitter was broken soon after we landed. But hurry. We can't waste time here."

"We'll hurry. But that way." Sam pointed to the creche entrance.

Joe shook his head, making a creaking, horrible sound of it. "No, Sam. He can't wait. I think he's dying! He was sick when I heard your call, but he insisted I bring him here. He-"

"You mean dying? There's a man with you?"

Joe nodded jerkily and pointed. Sam scooped the h'ght figure up in his arms.

Even on Earth, it was no great load for his larger body, and they could make much better tune than by letting the other try to run. Hal, he thought. Hal had been the youngest. Hal would be only fifty-nine, or something like that.That wasn't too old for a man, from what they had told him.

He flicked his lights on, unable to maintain full speed by the moonlight. The pointing finger of the other robot guided him down the slope and to a worn, weed-covered trail. They had already come more than five miles from the entrance to the creche.

"He ordered me to leave him and go ahead alone," Joe explained. "Sometimes now it is hard to know whether he means anything he says, but this was a true order."

"You'd have been wiser to stick to your car and drive all the way withyhinf,"

Sam suggested. He was forcing his way throufh-aitangle of underbrush, wondering how much farther they had to go.

"There was no car," Joe said. "I can't drive one now-my arms sometimes stop working, and it would be dangerous. I found a little wagon and dragged him behind me on that until we got here."

Sam took his eyes off the trail to stare at the battered legs. Joe had developed a great deal since the days on the Moon. Time, experience, and the company of men had shaped the robot far beyond what Sam remembered.

Then they were in a little hollow beside a brook, and there was a small tent pitched beside a cart. Sam released Joe and headed for the shelter. Moonlight broke through the trees and fell on the drawn suffering of a human face just inside the tent.

It took long study to find familiar features. At first nothing seemed right.

Then Sam traced out the jawline under the long beard and gasped in recognition. "Dr. Smithers!"

"h.e.l.lo, Sam." The eyes opened slowly, and a pain-racked smile stretched the lips briefly. "I was just dreaming about you. Thought you and Hal got lost in a crater. Better go shine up now. We'll want you to sing for us tonight.

You're a good man, Sam, even if you are a robot. But you stay away too long out on those field trips."

Sam sighed softly. This was another reality he could recognize only from fiction. But he nodded. "Yes, Chief. It's all right now."

He began singing softly, the song about a Lady Greensleeves. A smile flickered over Smithers' lips again, and the eyes closed.

Then abruptly they opened again, and Smithers tried to sit up. "Sam! You really are Sam! How'd you get here?"

Joe had been fussing over a little fire, drawing supplies from the cart. Now the robot hobbled up with a bowl of some broth and began trying to feed the man.

Smithers swallowed a few mouthfuls dutifully, but his eyes remained on Sam.

And he nodded as he heard the summary of the long struggle back to Earth. But when Sam told of the landing, he slumped back onto his pad.

"I'm glad you made it. Glad I got a chance to see you again before I give up the last ghost on Earth. I couldn't figure that radio signal Joe heard. Knew it couldn't be a human, and never thought of your making it here. B'ut now seeing you makes the whole trip worthwhile."

He closed his eyes, but the weak voice went on. "Hal and Randy and Pete- they're gone now, Sam. We waited up in the station three years, guessing what was going on here. Then we came down and tried to find somebody-some women-to start the race over. But there aren't any left. We covered every continent for twenty years. Pete suicided. The robots got busted, except for Joe. Then we came back here. And now I'm the last one. The last man on Earth, Sam. So I hear a knock on the door, and it's you! It's a better ending for the story than I hoped for."

He slept fitfully after that, though Sam could hear him moan at times. It was cancer, according to what he had told Joe, and there was no hope. Somehow, Joe had located a place where there were drugs to ease the pain a little, and that was all the help they could give.Joe told Sam a little more of the long search the men had made. It had been thorough. And they had found no trace of another living human being. The nerve gas had produced eventual death by nerve damage, as well as the initial insanity.

"Who?" Sam asked bitterly. "What race could do this?"

Joe made a gesture of uncertainty. "They talked about that. Mr. Norman told me about it, too. He explained that men killed each other off. One side attacked this side, and then our side had to hit back, until n.o.body was left. But I don't understand it."

"Do you believe it?"

"No," Joe answered. "Mr. Norman was always saying a lot of things I found he didn't really mean. And no man would do anything like that."

Sam nodded, and began explaining his theories. At first Joe was doubtful Then the little robot seemed to be convinced.^ dredged up small confirming bits of information from the long years of the search. They weren't important by themselves, but a few seemed to add to the total picture. A sign cursing the "sky devils" in Borneo, and a torn bit of a sermon found in Louisiana.

Twice during the long night Smithers awakened, but he was irrational. Sam soothed him and sang to him, while Joe tried to give him nourishment that was loaded with morphine. Sam knew little about human sickness, beyond the two medical books he had read. But even he could see that the man was near death.

The pulse was thready, and the breathing seemed too much effort for the worn body.

In the morning, however, the sun wakened Smithers again, and this time he was rational. He managed a smile. "Man goeth to his long home, and the mourners won't go about the streets this time. There won't be any mourners."

"There will be two," Sam told him.

"Yeah." Smithers thought it over and nodded. "That's good, somehow. A man hates not being missed. I guess you two will have to take on all the debts of the human race now."

His breath caught sharply in his throat, and he retched weakly. But he forced himself up on his elbows and looked out through the flap of the tent toward the hills that showed through the shrubbery and the blue of the sky beyond.

"There are a lot of debts and a lot of broken promises, Sam, Joe," he said.

"We promised to achieve some great things in the future, to conquer the stars, and even to make a better universe out of it. And we failed. We're finished.

Man dies, and the universe won't even know he's gone."

"Sam and I will know," Joe said softly.

Smithers dropped back onto the pad. "Yeah. That helps. And I guess there must have been some good in our existence-there had to be, if we could make two people like you. G.o.d, I'm tired!"

He closed his eyes. A few minutes later, Sam knew he was dead. The two robots waited to be sure, and then wrapped the body in the tent and buried it, while Sam recited the sc.r.a.ps of burial service he had picked up from his reading.

Sam sat down then where Smithers had died, staring at the world where no man lived or would ever live again. And the knot in his brain complex grew stronger and colder. He could not see the stars in the light of the day. But he knew they were there. And somewhere out there was the debt Smithers had given him-a debt of justice that had to be paid.

Anger and hate grew slowly in him, rising until he could no longer contain them. His radio message was almost a scream as he roused the computer.

"Can you make a thousand robots out of the material waiting? And can you model half of them after my brain as it is now and half after another robot I'll bring you to study, but without the limits you put on it before?"

"Such a program is feasible," the machine answered.

They wouldn't be just like him, Sam realized. De-Matre had said there was arandom factor. But they would do. The first thousand could find material for more, and those for still more. There would be robots enough to study all the books men had left, and to begin the long trip out into s.p.a.ce.

This time, there would be more than a tape education for them. Sam would be there to tell them the story of Man, the glory of the race, and the savage treachery that had robbed the universe of that race. They would learn that the universe held an enemy-a technological, warlike enemy that must be exterminated to the last individual.

They would comb the entire galaxy for that enemy if they had to. And someday, mankind's debt of justice would be paid. Man would be avenged.

Sam looked up at the sky and foreswore all robots for all tune to that debt of vengeance.

Hate spewed across the universe in a high crusade. Metal ships leaped from star to star and hurtled across the immensities to farther and farther galaxies. The ships sp.a.w.ned incessantly, and with each went the holy image of their faith and the unsated and insatiable hunger of their hate.

A thousand stars yielded intelligent races, but all were either nontechnical or peaceful. The great ships dropped onto their worlds and went away again, leaving a thousand peoples throughout the galaxies fitted with grat.i.tude and paying homage to the incredibly beautiful images of the supernal being called Man. But still the quest went on.

In a great temple-palace on the capital world of the Andromeda Galaxy, Sam's seventeenth body stared down at the evidence piled onto a table, and then across at the other robot, the scientist who had just returned from the ancient mother world of Earth, incredible light-years away. He stirred the evidence there with a graceful finger.

"That is how the human race died?" he asked again. "You are quite sure?"

The young robot nodded. "Quite sure. Even with modern methods and a hundred million workers, it took fifty years to gather all this on Earth. It has been so badly scattered that most was lost or ruined. But no truth from the past can be completely concealed. Man died as I have shown you, not as our legends tell us. There is no enemy now. Man was his own enemy. His were the ships that destroyed his people. He was the race we are sworn to exterminate."

Sam moved slowly to the window. Outside it was summer, and the trees were in bloom, competing with the bright plumage of the birds from Deneb. The gardens were a poem of color. He bent forward, sniffing the blended fragrance of the blossoms. Strains of music came from the great Hall of Art that lifted its fairy beauty across the park. It was the eighth opus of the !.

greatest robot composer-an early work, but still magnificent.
