Part 13

He cut me off again. "No fallout--or very little. What there is is gone within four or five minutes. Safe to go in after that, for the residue wouldn't mutate a fruitfly. Colonists don't know that ... closely guarded Endicott trade secret. Reason we let the Colonists store them. A fuel cylinder can be converted into a nuclear bomb, all right, but it will be the cleanest midget bomb ever built. Take fifteen or twenty of them to blow up even a third of the Colony. But that doesn't mean that one couldn't blow up the spaceport, or seriously injure hundreds of people throughout the fringe area. The ground tremor alone could do that. I told you what it did to this tractor. Has the force of a small earthquake, except that the tremors are three times as erratic. They can just shake you up a little, or break every bone in your body. Depends on where you happen to be standing. It follows a zigzagging pattern, so it can pass right by you."

All that didn't come in one shout, but I'm recording it that way because I didn't interrupt him, and though he must have stopped once or twice to take a deep breath, and keep a sharp lookout for another ambulance I wasn't aware of any break in what he was saying. He was trying his best to make it crystal clear, if only to calm me down a little.

Some of it was reassuring, but not what he'd said about the spaceport. A clean bomb with little or no fallout can leave you just as dead if you're unfortunate enough to be blown up by it.

You see things sometimes you can't bring yourself to talk about, even to close friends when the horror has receded a little and you know it can't come back in a physical way to torment you.

So I'm going to draw the veil over most of what we saw when we passed through about five square miles of the Colony, before the clear-away broadened out to twice its previous width and we headed out across the desert toward the spaceport.

We couldn't be sure, even then, just where the explosion had taken place, because it was only the fringe area we passed through. It hadn't been laid waste by the blast and there were only five or six demolished buildings. If the big square which stretched between the Endicott plant and the aerators had been a built-up section instead of a square the property damage might have been just as great and would not have seemed ruinous.

But there was one other difference. The Endicott square had been unpopulated, with just one tractor moving out from the long line of tractors on the far side. The five miles of Colony we passed through had been the opposite of unpopulated. Its streets and squares and playgrounds and vehicle-parking areas had been thronged with people.

They were still thronged with people but some of them were lying prone, and others were leaning dazedly against the walls of buildings which had remained for the most part undamaged and still others, who no longer seemed to be in a state of shock, were bending over the slumped bodies of the grievously injured and the dying, doing their best to console them and ease their pain.

I'm drawing the veil on the rest of it--the blood and the screaming--because it was pretty awful, and what possible purpose would be served if I described it? How could it benefit anyone? It would serve as a reminder of how cruel life can be at times, how uncertain and terrible. We know that, don't we? So ... to hell with it ... I say that in a very reverent way, with awe and respect, and not profanely. But it's best to consign it where it belongs, to hell, and not let it paralyze all action and make you give up when there are still sunsets, and the laughter of children, and the happiness of lovers, and ten thousand other things that are worth fighting to preserve.

It took us less than eight minutes to arrive at the spaceport, dusty from head to foot, with sand choking our lungs and gasping a little from oxygen shortage, because when there's a stiff wind blowing over the desert the aerators don't function at peak efficiency.

I didn't know there was anything wrong until the tractor began to zigzag a little, about three hundred feet from the massive, steel-mesh gates of the spaceport.

He had strength enough left to tug at the brakes and bring the tractor to a grinding halt before he slumped against me, with a strangled sob that chilled me to the core of my being. It chilled me and stunned me and frightened me, because I'd never thought that anything like that could happen.

He was frail, all right, and had the look of a man whose health had been steadily failing ... no doubt partly brought about by the battle he'd been waging with Wendel. And he'd mentioned something about heart-trouble--

The trouble was, I hadn't taken all that too seriously, because you never think that someone who has displayed extraordinary energy and firmness of will is going to collapse right when you need him most.

I swung about and looked at him, and his pallor gave me an even worse jolt than the way he'd moaned and sagged heavily against me.

He gripped my arm and tried to speak, but the words wouldn't come. His lips moved soundlessly for a moment and then--they stopped moving. His body stopped moving too. All at once, as if a clock had stopped ticking inside of him, and Time had stopped ticking for him forever just because his life and the clock were bound up together, intricate parts of the same mechanism, and if the clock stopped there was no way his life could be prolonged.

I knew he was dead before I reached out and touched him. I could tell by the dull, unseeing glaze which had over-spread his pupils and the terrible stillness which had come upon him. A stillness and a rigidity that made it impossible for me to doubt what the alarm bells were telling me as well. They had started ringing again, but this time it wasn't so much an alarm they were sounding as a dirge.

It was impossible for me to doubt, but I still had to make sure, as he would have wanted me to do, by feeling for a heartbeat that wasn't there and satisfying myself in other ways. It was an obligation I couldn't evade and had no intention of evading.

It took me less than a minute and a half--a time limit I kept firmly in mind--to fulfill that obligation. Then I descended from the tractor and headed for the steel-mesh gates of the spaceport on the run.

"Ralph!" she cried, running to meet me as I walked into the big, steel-walled enclosure where Commander Littlefield and eight or ten or possibly twelve men in gray skyport-technician uniforms were working over a long metal cylinder that Death had started working on well ahead of them. He was the expert and they were just amateurs doing the best they could to beat the time limit he had set for them. With a grim chuckle, no doubt, because, as I said once before, Death is a weird-o.

Joan's arms went around my shoulders and she crushed herself against me, and kissed me hard on the mouth. Then she let go of me and moved quickly to one side, so that Commander Littlefield could talk to me without interference or a moment's delay. She seemed to know without waiting for me to say a word how important that was.

One look at Littlefield's white face told me all I really wanted to know. But I decided that if he could fill in the details for me in half a minute I could risk setting another time-limit in my mind and clocking him second by second by second as he talked.

"A nurse at the hospital got word to us you'd be doing your best to get back here, Ralph," he said. "The Wendel police have orders to blast you down on sight, but now that you're here I can protect you--or you can protect yourself. I've got your papers and insignia. Right now that's not so urgent as what's happening inside this Endicott fuel cylinder. It's been triggered to build up to critical mass by a Wendel agent. A Colonist brought it here and we've been trying to dismantle it. But we don't know just how to go about it and we don't dare experiment. We've taken a few _small_ risks, naturally. We've had to. But we're getting nowhere, and what looks like a small risk could turn out to be a big one. We don't even know how much time we've got!"

He spoke almost calmly, without raising his voice, but there was nothing calm about the way he looked. The time limit I'd set to clock him by had run out and now it was my turn. I was going to have to ask him to do something that might seem only a little less terrible to him than being blown apart by a nuclear explosion.

But it would have to be done--and fast.

I clocked myself as I talked, allowing myself about forty seconds. "Those cylinders build up to critical mass when they've been tampered with and triggered to explode in about forty-five minutes," I said. "Don't ask me how I know, because I haven't time to explain. I _do_ know--you can take my word for it. I knew the cylinder was here, and I was hoping you'd find a way--"

I caught myself up. "Never mind that now. Just listen. I don't know how long it took the Colonist to bring it here or how long you've been working over it. But it hasn't exploded yet. _So there's still a chance we can get it out into space before it blows up!_"

He looked at me as if he thought I'd gone suddenly quite mad. I finished what I had to say fast, because I knew it would take eight or ten more minutes for him to recover from his first shock, and issue orders, and have the cylinder carried on board his big sky ship--his pride and glory--and for the sky ship to rise from its launching pad and be blown apart in space.

He'd have to get all of the crewmen off as well and set the robot controls and if there were any passengers still on board--I refused to let myself think about that.

"It may be too late," I went on. "We may all be as good as dead right now. But we've got to try. Do you understand? You've got to get that cylinder on the sky ship, set the controls and send it out into space. _It must be done at once. Every second counts._"

He recovered from the shock faster than I'd dared to hope. The grin that hovered for the barest instant on his lips startled me until I realized it was a very special kind of grin--the kind of grin only a man who is about to part with something that means just about as much to him as his own life would be capable of ... if he had a non-eradicable streak of wry humor deep in his nature as well.

"Ralph, I've always looked upon people who put property above human life as just about the lowest worms that crawl. But for a minute--God pity me--I almost felt that way. It's just that--it's fifty billion dollars worth of big, tremendous sky ship and that cylinder is so small--"

"It won't seem small if it blows up and takes the spaceport with it," I said. "It won't seem small at all."

"I know, Ralph. I said once I was old enough to be your father and I still think I am. But if you put me across your knee and gave me the drubbing a dumb six-year old would rate I'd have no right to complain. I should have thought of it myself."

"We don't always think of things that stand out like sore thumbs when we're under tremendous stress," I said. "Don't blame yourself for being human, Commander."

"I hope it won't take me much longer than that to finish the job, Ralph," he said. "I'll do my best. There are only three crewmen on board and all of the passengers have been cleared."

He swung about without another word and went striding out of the enclosure.

I would have followed him if Joan hadn't picked that moment to come back into my arms. It held me up for a minute or two.

* * * * *

The incandescent burst of flame that makes a big sky ship's ascent into space seem for an instant almost cataclysmic, as if the sky itself had been ripped apart in some terrible and incomprehensible way, came exactly eight minutes, thirty-two seconds later.

I timed it myself, not mentally this time but with a watch in my hand. I stood with Joan at my side a hundred feet from the launching pad, watching the cylinder disappear into the sky. It was the cylinder and not the big rocket itself that I seemed to see as I stared upward, as if the sky ship had turned to glass and the deadly thing it was carrying out into space was beginning to stir and vibrate in a quite ghastly way, with its contours enlarged to sky-spanning dimensions under the glass.

To my inward vision it was bigger than the ship itself and it was hard to understand how even a huge sky ship could be carrying anything so enormous and death-freighted when a short while before it had been discharging passengers in the bright Martian sunlight who had given no thought to Death ... only what life had in store for them on a new world.

My fingers were clenched around the watch and I wasn't even aware that Commander Littlefield had joined me until he tapped me on the arm.

"We can see and hear it when it happens--all of it, just as if we were taking it out into space ourselves. Every tele-communicator on the sky ship is turned on and tuned to big screen wave length. If there was a crewman on board he could talk to us and we could talk to him."

"Thank God there isn't a living man on board," I breathed.

"Yes," he said, nodding. "Yes, we can be thankful for that. And for our lives as well. There are four big screens here, but we may as well watch the one in the port clearance building. It's the largest of the four--if size makes any difference when about all we'll see when the cylinder explodes is a blinding flare. We won't see the bulkheads collapsing, or a robot cyb crumbling, that's for sure. It will happen too fast."

"What good will it do us to watch at all?" Joan asked. "I'd rather stay right here. We'll see the flash, won't we?"

"You'll see it, all right," Littlefield said, grimly. "It will look like an exploding star for about ten seconds. My sky ship--an exploding star. I never thought it would ever come to that."

He started to turn away, thinking, no doubt, that I'd fallen in with Joan's idea of passing up a view of it on the screen. But I hadn't at all and when he started walking toward the port clearance building I was right at his side. So was Joan, because she was that kind of a wife. There were a lot of questions I wanted to ask him--questions of the utmost urgency, such as how much progress he'd made in finding out who had shot the dart at me from high up on the spiral and just what news he'd received from the hospital, when Nurse Cherubin had informed him I was trying to get back to the spaceport, that went beyond that bare statement--I was sure she'd briefed him in detail--and ... well, a lot of questions. But this hardly seemed the right time to ask him, because his inner torment was too great.

I could sympathize and understand, because I knew what a hell he was passing through. Nothing could prevent the destruction of his sky ship, but he had to see it with his own eyes, no matter how much agony it caused him.

He didn't have to do any explaining to the Port Clearance men, because they'd either assumed he'd pick out their screen well in advance of our arrival or their own curiosity had proved overmastering.

The screen was lighted and the sound tracks whirring when we walked into the projection room. It was just like walking into the sky ship's chart room and staring across it at the four robot giants who had followed both emergency instructions in space and the routine kind and were doing their best to perform a man's job now. A mechanical best, which meant, of course, that they had no way of knowing how close they were to annihilation. They would be blown apart without pain and had nothing to lose that a man would have valued. But they were not men, and who can be sure that mechanical brains and the thought processes which take place in them are not faintly tinged with emotional coloration?

Probably not ... for it would have been something that laboratory tests have never succeeded in establishing. A cybernetic brain can become fatigued, yes--but it is not really a human fatigue. It is on the metal-fatigue level. But knowing all that, a chill would have gone through me if the robots had been able to talk to us.

The image on the screen was three-dimensional, and in full color and the illusion that we were standing right in the sky ship's chart room was so startling that Joan whispered: "I wish we'd stayed outside. It's terrifying. Almost as if ... we could be blown up ourselves when the blast comes."

"No danger of that," I said, squeezing her hand reassuringly. "You'd better sit down."

There were ten hollow-tubed metal chairs in the room, but all except one were occupied. I reached out and drew it toward her, but she shook her head. "No, I'll stand, Ralph. I may want to leave in a minute."

One of the port clearance lads got up and offered Commander Littlefield his chair, assuming I'd take the one that Joan had refused. But we were both of one mind about standing. Only Littlefield sat down, as if the burden of torment which rested upon him had added ten years to his age.

No sound at all came from the screen for a full minute. Then a scream broke the stillness. It was so totally unexpected, so horrifying, that two of the port clearance men leapt to their feet, sending their chairs spinning backwards. Commander Littlefield was on his feet too, but he hadn't leapt up. He'd arisen jerkily, his hands pressed to his temples, as if to shut out the sound or keep his head from bursting.

We saw her then. She had come into the chart room and was staring directly at us, and just knowing she could see us as clearly as we could see her made her plight seem even more terrible. To me, at least, because it wasn't hard to imagine what was passing through her mind.

_I'm alone on the ship ... just as I feared. They've sent me out alone into space. If Commander Littlefield isn't on board ... if he's in that room watching me with all those other men ... what else can it mean?_

She'd be ten times as sure of it if she'd been inside the port clearance projection room and knew what it looked like, and I was almost certain she had, because there was an unmistakable look of recognition in her eyes, and the Port Clearance building was where they took passengers for questioning.

She looked as she always had, with her hair piled up high on her head and the full lips drowsily sensuous, and her breasts thrusting firmly upward against the tight-clinging fabric that ensheathed them just below the curve of her throat, and the soft whiteness of her upper bosom.

Only her eyes had changed. Stark terror looked out of them and suddenly as she stared at us she pressed one hand to her throat and swayed back against the bulkhead on the right side of the doorway. It brought her up short. But I was sure that if it hadn't she'd have gone right on retreating backwards until she either started screaming again or crumpled to the floor in a dead faint.

She neither screamed again nor fainted, for Commander Littlefield gave her no time to succumb to utter panic. But if his voice hadn't rung out as sharply as it did--at the precise moment that it did--the outcome might have been quite different.

"Why did you return to the ship?" he shouted. "Why did you do such a reckless thing? Was it because we suspected you? Was it because you knew we were about to place you under arrest? Answer me! Your life may depend on it."

"Yes ... I went back," she said. "But only to get ... something I didn't want you to find. I was pretty sure I'd hidden it where you'd never think of searching, but when you started suspecting me--"

"I see. A damaging piece of evidence? Something of the sort?"

She nodded. "Yes ... yes ... a paper. It would have proven my guilt."

"You admit your guilt then? We can still save you, but not if you go on lying, clinging to the story you told us. Every part of that is false."

"No, no!" She almost screamed the words. "Most of what I told you was true. My brother did work for Wendel and ... I didn't know that he had died. I just found that out a few hours ago. I came to Mars to help him, to save him if I could. I was a Wendel agent, but only because I had no choice. They threatened to kill my brother ... used that as a weapon to make me spy for them and do--uglier things."

Her voice rose pleadingly. "Bring the ship back. Don't send me out alone into space. You can't be that cruel--"

"We can't bring the ship back. But we can save you. Just tell the truth. Wendel knew that the Board was sending someone to Mars to investigate the combine, a man who couldn't be bribed to shut his eyes to what he was sure to see here. You had instructions to kill that man before he could set foot on Mars. Wendel wanted him killed because they knew the Board was backing him to the hilt and he had been given enough authority to make him the most dangerous kind of adversary. Wendel also knew that you were the most resourceful and intelligent agent in their employ.

"You proved that, to my satisfaction, when you did what no one has ever done before--outwitted a Mars' rocket security alert system by concealing yourself in a cybernetic robot. I'm sure it didn't take Wendel long to discover that you are as intelligent as you are beautiful--both valuable assets in a secret agent. Priceless assets. The time is very short. Am I right so far?"

"Yes ... it's all true. Please ... help me!"

"You tried to kill, without success, the man the Board was sending to Mars to investigate and crack down on both Wendel and Endicott. You tried to kill him three times."

"No, only once. I'm telling you the truth. I didn't fire that dart. There were other Wendel agents on board. One tried to blow up the ship. And there were other Wendel agents in New Chicago, with instructions to assassinate him if they could."

"I see. But you did try to kill him in New Chicago. Why did you come to Mars, if you didn't intend to try again?"

"I told you. I didn't lie when I said I came to save my brother, that I wanted to see Wendel exposed ... forced to face criminal charges. When I tried to stab him in the New Chicago Underground and failed ... I realized what Wendel had done to me, what a vicious person I'd become. I decided I couldn't go on being that kind of person any longer, not even to save my brother. I took the only other way I could think of to keep Wendel from killing my brother. I _am_ a resourceful woman, I _am_ intelligent ... why should I deny it? I might have made the Wendel Combine think twice about killing him. But now my brother's dead and--"

Her shoulders sagged and a look of torment came into her eyes.

"All right. One thing more. When that Wendel agent surprised you in the chart room and the man you'd tried to kill saved you ... why were you so frightened? Why did the agent go into such a rage? You must have thought he intended to kill you. And if you were both Wendel agents--"

"I wasn't supposed to be on the ship. He knew it, and must have been pretty sure I'd turned traitor. He knew all about my brother. There wasn't much he didn't know about me, because he was a very high-placed agent. He knew I had every reason to hate Wendel. And I think he was also the kind of man who turns sadistic when he has a woman completely at his mercy."

She saw me then. I could tell by the way her eyes widened and then fastened on me, staring straight past Littlefield as if he was no longer her only accuser.

But she was mistaken if she thought I had any desire to accuse her. I was furious with Littlefield, sickened by his relentless attack on her and if I hadn't been stunned for a moment, caught up in a kind of hypnotic spell by the suddenness of that attack and the startling candor she'd displayed in replying to it I'd have interfered sooner.
