The Time Axis

it would repeat endlessly whenever anyone chose to play this recording over.

But now, as the bodies began to crumble, I saw a change slip across Paynter's face. I saw it go blank, then suddenly go quite bright with a blaze of awareness – and then totally blank.

His knees sagged. He folded up and dropped limply forward. Someone jumped to his side from the crowd at his back, caught him and eased him to the dusty floor. As he fell I could see beyond him the small, brightly colored body that was Topaz, collapsed without a sound.

There was milling confusion around the two for a moment. Then Paynter stirred and the crowd backed away a little. Paynter sat up, consciousness returning visibly to his blank face. Topaz, beside him, stirred and moved her hand, lifted it and, with her eyes still closed, brushed the clustering curls from her face with a curiously innocent vanity.

At my elbow Paynter said, 'All right, that was that. A moment's faintness. Neither of us suffered anything worse. But let's go back again to the moment the shell cracked and Topaz and I fainted. There was a crowd outside, waiting to see what would happen. You'd be surprised how easy it is to draw a crowd. They didn't take long to assemble, via matter-transmission, once word got out. Some of our other cameras caught an interesting detail or two.'

Now I saw a rolling slope thronged with men and women. Figures were toiling up from a plain below, where last I had seen the forests of northern Canada stretch unbroken. In the far distance a low white building gleamed in the sunlight among orchards.

'That building,' Paynter told me, 'is the Kerry Plum Orchard transmitter. All these people came through it. They came from all over the galaxy, of course. No way to trace where they started from. Which is a pity because – well, look.'

I looked – and saw my own face.

Duplication doubled and redoubled. My head swam as

I tried to realize it, to count up how many Jerry Cortlands were in existence in this one space and time. One had fallen to dust in the cave. One sat here in the Swan Garden beside Paynter. One strolled up the hillside toward the cavern, casually, through the crowd. It was myself, all right. I wore rather ragged shorts and a tattered pullover.

I turned left around a rock with part of the crowd and then there was a sudden humming excitement all over the hillside and a flash of reddish light from the cave.

'We've gone back again to the moment when the bodies began to disintegrate,' Paynter reminded me. 'Down in the cave Topaz and I are collapsing. Up here – watch yourself.'

I saw the same look of dazed wonder melt into blank-ness on my pictured face. I saw myself fall.

'When you woke again,' Paynter was saying, 'you were in the transmitter room by the City. Topaz was with you. That was when your memories started. Remember?'

'You mean – that was me?' I demanded. 'That man who came with the crowd? The me sitting here now? Oh no, that isn't possible! I remember! I went to sleep in the cave in the Twentieth Century and woke here. I never came out of a transmitter and joined a crowd in the Laurentians. You told me you'd wakened me in the cave!'

'Not, exactly, no,' Paynter said. 'I just gave you your head. There was so much here that nobody understood, you see. I wanted you to go your own way until I knew all I could learn from you. Then I told you the truth. What could be fairer than that?'

'But I'm not that man on the hillside! Who was he? Where did he come from? He isn't me!'

'Well, you're that man. You saw what happened to the bodies in the cave. Your duplicate, my duplicate, Belem's, the woman's – they all disintegrated. As for who you are, I don't know. It's odd but not unheard of. With galaxy-wide colonization there must be a good many people in stray corners who have never been registered. You're one of them.

'We tried but there's no record of your prints and history. However, you are the man who fainted on the hillside. It took you longer to recover than it did us and when you woke you called yourself Cortland and you've just given me some very fantastic history. Which rings true, incidentally. You believe it. You aren't faking.'

'Of course not. I was in the time chamber with the others!'

'You fell to dust, I suppose.' Paynter's voice was impatiently amused. 'Wait a minute. I thought I noticed something in the crowd near you. Hold on.'

I felt him move. The picture flashed on before me, picked up again the scene on the slope. Paynter gave some orders in an undertone, and the camera paused, halting in mid-stride a man who had just entered the edge of the picture.

It was De Kalb.

No, not De Kalb – Belem. He turned his face to the camera and light glinted on the quicksilver eyes.

The daylight flashed suddenly red again. The crowd nearby surged, chattering around me – my duplicate – as he fell. And Belem staggered. You could see the cold resolute Mechandroid brain gather itself to resist whatever assault this was upon its integrity. And the Mechandroid succeeded where the merely human had failed. Belem stumbled a little, leaned against the rock I had seen myself circle a moment before in the film, slid down so that he half crouched against it, his face in his hands.

Then quietly, in about a quarter of a minute, he rose and walked back toward the Kerry transmitter, moving stiffly even for him, his face bewildered.

Paynter was saying in my ear, 'So that's where he was!' But deep in the center of my mind a stirring of surprise gathered all my attention. Belem was watching too. Belem was thinking in almost the same words Paynter used, 'So that is what happened! Now – now I almost understand.'

16. THE SUBTERRANE

There was silence in the Swan Garden for a long moment. Then Paynter lifted the helmet from my head and stood looking down thoughtfully at me. The crystalline bower came back around me. I was looking into Murray's face but it was Paynter, from Colchan Three and this middle future, who spoke.

'There were four asleep in the cave,' he said. 'There were four who blanked out for a time when the sleepers disintegrated. That must mean we living four were duplicates in more than appearance to those who were destroyed. I don't understand, of course.

'The integrating machines are working on it now. Eventually they'll hand us all the factors and their conclusions. Meanwhile, Cortland, I think I caught an impression of yours while our minds were in rapport. Is Topaz a duplicate of that woman in the cave?'

'Dr. Essen,' I said. 'I think she is. Yes.' But silently, to myself, I was thinking. 'They all have identities but me. I'm myself. And yet I saw Jerry Cortland dissolve. That must mean that I'm the nameless man, the one who came up the hillside from nowhere and fainted. When he woke up, he was Jerry Cortland – me. And I'll never dare sleep in this world for fear that when I wake I'll be – him. Not myself. I saw myself disintegrated in the cave for a purpose, by some means I don't understand. I'm dead. When this man wakes up, I'll – '

'All right, Cortland,' Paynter said briskly. 'I'll leave you here for an hour. You'll be quite safe, of course. Topaz will rejoin you in a moment or two.'

'Am I a prisoner?' I asked.

'Well, no, not exactly.' He gave me a grim smile. 'You want the same things we do, I suppose. An answer to all this. I'm assuming you've told us the truth. I'm as sure of that as it's possible to be. Of course you may have powers you've been able to hide from us, so we'll keep an eye on you until we know more. Topaz will bring you to
