The centre of the plateau was a pulsing blur, as the air trapped in the basin throbbed upward into the sun. I drove straight towards it, Mayer stiffening in his seat. A hundred yards from the basin’s edge the air suddenly cleared and we could see the tops of the megaliths. Mayer leapt up and swung out of the door onto the running board as I cut the engine and slammed the half-track to a halt by the rim. We jumped down, grabbing flare pistols and shouting to each other, slid into the basin and sprinted through the boiling air to the megaliths looming up in the centre.
I half-expected to find a reception party waiting for us, but the megaliths were deserted. I reached the pentagon fifty yards ahead of Mayer, climbed up and waited for him, gulping in the molten sunlight.
I helped him up and led him over to one of the megaliths, picked a column and began to read out the entries. Then I took him round the others, recapitulating everything I had discovered, pointing out the blank tablet reserved for Earth.
Mayer listened, broke away and wandered off, staring up dully at the megaliths.
‘Quaine, you’ve really found something,’ he muttered softly. ‘Crazy, must be some sort of temple.’
I followed him round, wiping the sweat off my face and shielding my eyes from the glare reflected off the great slabs.
‘Look at them, Mayer! They’ve been coming here for ten thousand years! Do you know what this means?’
Mayer tentatively reached out and touched one of the megaliths. ‘“Argive League XXV… Beta Tn-”’ he read out. ‘There are others, then. God Almighty. What do you think they look like?’
‘What does it matter? Listen. They must have levelled this plateau themselves, scooped out the basin and cut these tablets from the living rock. Can you even imagine the tools they used?’
We crouched in the narrow rectangle of shadow in the lee of the sunward megalith. The temperature climbed, forty-five minutes to noon, 105° ‘What is all this, though?’ Mayer asked. ‘Their burial ground?’
‘Unlikely. Why leave a tablet for Earth? If they’ve been able to learn our language they’d know the gesture was pointless. Anyway, elaborate burial customs are a sure sign of decadence, and there’s something here that suggests the exact opposite. I’m convinced they expect that some time in the future we’ll take an active part in whatever is celebrated here.’
‘Maybe, but what? Think in new categories, remember?’ Mayer squinted up at the megaliths. ‘This could be anything from an ethnological bill of lading to the guest list at an all-time cosmic house party.’
He noticed something, frowned, then suddenly wrenched away from me. He leapt to his feet, pressed his hands against the surface of the slab behind us and ran his eyes carefully over the grain.
‘What’s worrying you?’ I asked.
‘Shut up!’ he snapped. He scratched his thumbnail at the surface, trying to dislodge a few grains. ‘What are you talking about, Quaine, these slabs aren’t made of stone!’
He slipped out his jack knife, sprung the blade and stabbed viciously at the megalith, slashing a two-foot-long groove across the inscriptions.
I stood up and tried to restrain him but he shouldered me away and ran his finger down the groove, collecting a few fragments.
He turned on me angrily. ‘Do you know what this is? Tantalum oxide!
Pure ninety-nine per cent paygold. No wonder our extraction rates are fantastically small. I couldn’t understand it, but these people—’ he jerked his thumb furiously at the megaliths ‘—have damn well milked the planet dry to build these crazy things!’
It was 115°. The air was beginning to turn yellow and we were breathing in short exhausted pants.
‘Let’s get back to the truck,’ I temporized. Mayer was losing control, carried away by his rage. With his big burly shoulders hunched in anger, staring up blindly at the five great megaliths, face contorted by the heat, he looked like an insane sub-man pinned in the time trophy of a galactic super-hunter.
He was ranting away as we stumbled through the dust towards the half-track.
‘What do you want to do?’ I shouted. ‘Cut them down and put them through your ore crushers?’
Mayer stopped, the blue dust swirling about his legs. The air was humming as the basin floor expanded in the heart. The half-track was only fifty yards away, its refrigerated cabin a cool haven.
Mayer was watching me, nodding slowly. ‘It could be done. Ten tons of Hy-Dyne planted round those slabs would crack them into small enough pieces for a tractor to handle. We could store them out at the observatory, then sneak them later into my refining tanks.’
I walked on, shaking my head with a thin grin. The heat was hitting Mayer, welling up all the irrational bitterness of a year’s frustration. ‘It’s an idea. Why don’t you get in touch with Gamma Grus? Maybe they’ll give you the lease.’
‘I’m serious, Quaine,’ Mayer called after me. ‘In a couple of years we’d be rich men.’
‘You’re crazy!’ I shouted back at him. ‘The sun’s boiling your brains.’
I began to scale the slope up to the rim. The next hour in the cabin was going to be difficult, cooped up with a maniac eager to tear the stars apart. The butt of the flare pistol swinging on my knee caught my eye; a poor weapon, though, against Mayer’s physique.
I had climbed almost up to the rim when I heard his feet thudding through the dust. I started to turn round just as he was on me, swinging a tremendous blow that struck me on the back of the head. I fell, watched him close in and then stood up, my skull exploding, and grappled with him. We stumbled over each other for a moment, the walls of the basin diving around us like a switchback, and then he knocked my hands away and smashed a heavy right cross into my face.
I fell on my back, stunned by the pain; the blow seemed to have loosened my jaw and damaged all the bones on the left side of my face. I managed to sit up and saw Mayer running past. He reached one hand to the rim, pulled himself up and lurched over to the halftrack.
I dragged the flare pistol out of its holster, snapped back the bolt and trained it at Mayer. He was thirty yards away, turning the nearside door handle. I held the butt with both hands and fired as he opened the door. He looked round at the sharp detonation and watched the silver shell soar swiftly through the air towards him, ready to duck.
The shell missed him by three feet and exploded against the cabin roof. There was a brilliant flash of light that resolved itself a fraction of a second later into a fireball of incandescent magnesium vapour ten feet in diameter. This slowly faded to reveal the entire driving cabin, bonnet and forward side-panels of the half-track burning strongly with a loud, heavy crackling. Out of this maelstrom suddenly plunged the figure of Mayer, moving with violent speed, blackened arms across his face. He tripped over the rim, catapulted down into the dust and rolled for about twenty yards before he finally lay still, a shapeless bundle of smoking rags.
I looked numbly at my wristwatch. It was ten minutes to noon. The temperature was 130°. I pulled myself to my feet and trudged slowly up the slope towards the half-track, head thudding like a volcano, uncertain whether I would be strong enough to lift myself out of the basin.
When I was ten feet from the rim I could see that the windscreen of the half-track had melted and was dripping like treacle onto the dashboard.
I dropped the flare pistol and turned round.
It was five minutes to noon. Around me, on all sides, enormous sheets of fire were cascading slowly from the sky, passing straight through the floor of the basin, and then rising again in an inverted torrent. The megaliths were no longer visible, screened by curtains of brilliant light, but I groped forward, following the slope, searching for what shade would still be among them.
Twenty yards farther on I saw that the sun was directly overhead. It expanded until the disc was as wide as the basin, and then lowered itself to about ten feet above my head, a thousand rivers of fire streaming across its surface in all directions. There was a terrifying roaring and barking noise, overlaid by a dull, massive pounding as all the volcanoes in the volcano jungle began to erupt again. I walked on, in a dream, shuffling slowly, eyes closed to shut out the furnace around me. Then I discovered that I was sitting on the floor of the basin, which started to spin, setting up a high-pitched screaming.
A strange vision swept like a flame through my mind.
For aeons I plunged, spiralling weightlessly through a thousand whirling vortexes, swirled and buffeted down chasmic eddies, splayed out across the disintegrating matrix of the continuum, a dreamless ghost in flight from the cosmic Now. Then a million motes of light prickled the darkness above me, illuminating enormous curving
