repair genetic damage. Without hades, old viruses in our DNA start popping up and antagonizing our immune system. We become more prone to cancer or autoimmune disease.’
‘Like a time bomb,’ Montoya said. ‘Awful. I assume you’ve found a way to defuse it?’
‘I’m close. The solution isn’t simple, but it involves training bacteria to pump in just the right amount of hades, at the right times – not too much, and not too little. And we have to jam the tattletale signals from our mitochondria. I’m pretty sure I can fool our bacterial partners into turning back our clocks. We live longer – maybe a lot longer.’
Montoya flexed his fingers and compressed his lips with something like satisfaction. ‘Why go against the wisdom of nature?’ he asked softly, fixing me with a limpid stare. ‘Why live longer than the “judges” want us to?’
‘We’re big kids now. We made fire. We made antibiotics. Did the bacteria give us permission to go to the moon? We’re ready to take charge and be responsible for our own destiny. Screw the old ways.’
Montoya grinned. ‘I’ve never tried to think like a germ.’
‘I do it all the time,’ I said. ‘It’s enlightening.’
Montoya made a face. ‘A whole new view of human existence,’ he said. ‘Makes me dizzy.’
‘Not entirely new.’ I reached into my satchel and pulled out a list of the researchers whose work had helped me. ‘There are going to be a lot of Nobel prizes for these people in the next decade.’ I was taking another chance, but I would not work for a man who was always sniffing for someone more famous. Montoya had to believe that I really had the goods.
‘How about your Nobel?’ he asked.
I shrugged. ‘Not important,’ I said. ‘I’m in it for the long haul.’ Sometimes I whispered that phrase to myself to get to sleep at night, like counting sheep. The Long Haul. The Really Long Haul.
A butler – Swedish blond and about sixty years old – carried a tray of glasses and a bottle of 1863 Malmsey Madeira. He poured, and Montoya handed me a crystal glass.
‘Nobel prizes won’t be half of it,’ Montoya murmured. He narrowed his eyes as if about to fall asleep and leaned his head back. Here it was. My angel was about to pull out his flaming sword. ‘You have a compelling vision. How can I help you to get on with your work?’
I took out the pictures shot by the Alvin crew the month before. Montoya thumbed through and reversed them to look at my notes.
‘There are some deep places I’d like to visit,’ I said, ‘and some problems I’d like to solve. I’d like to do it in secret…Until I find out whether I’m a major-league idiot, or whether I’m really on the edge of a revolution.’
‘What will I get out of it?’
‘Nothing all to yourself,’ I said. ‘My work is for everybody. No patents, no marketing exclusives. I’m pretty hard-headed that way. But maybe – just maybe – you’ll get a crack at living a few hundred years longer. Or a thousand. Or ten thousand.’
Montoya lifted his finger and seemed to wag it in time to unheard music. His eyes got dreamy. ‘Eternity means for ever without time. Like standing still for ever. Did you know that?’
I shook my head. Philosophy has always been my weak point. Why argue about printed words when there are thousands of proteins and enzymes, the verbs and nouns of living biology, to memorize and understand?
‘You know what I want to do, Hal?’ Montoya asked. He stared out over the Plexiglas shield at the end of the porch and lifted his golden Madeira to the breaking waves. ‘I want to build a huge starship. I want to travel to other star systems, stand on new worlds, and party with all my friends on my millionth birthday. I want to dip my feet in the waters of unknown shores and help lovely, enthusiastic women become mothers.’
Montoya finished his glass in one big gulp. ‘I have all the money I need, Hal. I just don’t have enough time.’
By ten the next morning, I had a pledge from Owen Montoya for three million dollars.
The Mary’s Triumph had managed to cruise between three massive chimneys. Outside, hydrogen sulfide had leaped from a stinking trace to levels toxic to humans. Where steam-boiler temperatures did not scald, life flourished. Tube worms gathered in weird bouquets between the chimneys. White crabs crawled through like ants in grass. No alien city would ever look so strange or so weirdly beautiful.
For a second, I spotted something gray and serpentine just beyond a nearly solid wall of tube worms. I tried to call it to Dave’s attention, but by the time he turned to look, it had faded like smoke. A current? A ribbon of bacterial floc scalded loose by a geyser?
‘We have about two hours,’ Dave reminded me. ‘Those chimneys have to be eighty feet high.’
‘That could happen in a few months down here.’
‘It’s still pretty damned wonderful. One of the biggest fields we’ve found.’ Dave shook his head. ‘But you’re not interested in tube worms.’
‘Not right now.’
Tube worms are born empty, then suck bacteria into their hollow guts and rely on them to process sulfides and provide all of their nourishment. They live about two and a half centuries, three at the most. Impressive, but they still take their marching orders from germs.
I wanted evidence from earlier times, when the host was still putting up a good fight and the bacteria were still flying their true colors.
‘Under the plume,’ I reminded Dave. ‘Let’s go east about a hundred yards. The walls seem to open up, and there are already fewer vents.’
‘So there are,’ Dave said, comparing the image from our forward-looking sonar with a terrain map made several months ago – a map, incidentally, that did not show Field 37.
He rechecked our position, triangulating between the pulses from the mother ship and the transponders on the seafloor, then pushed the stick forward. Two, three, four knots; a gentle glide through the forest, over tube worms and around spewing, roaring geysers.
We passed near enough to look up at a flange thrusting almost six feet from the side of a tall chimney. The bottom of the flange was painted with rippling, silvery pools. Superheated mineral-rich water, refusing to mix with the cooler local fluid, gathered under the flange’s rough surface and reflected our lights.
‘I get nervous around these puppies,’ Dave said. ‘Had one almost topple over on me when I was working for NOAA. Just clipped it with a manipulator arm, then, wham.’
‘That’s not common, is it?’ I asked.
‘Not very,’ Dave admitted. ‘But once is enough. Well, shit – I mean, dog poop – on it.’
That just didn’t sound like reliable Dave the Christian man, the steady pilot of NOAA DSVs. I gave him a concerned look, but he was too busy to notice.
We made our way between the long, winding canyon walls, pushing along at half a knot. The vents were behind us now, but wooly bacterial clumps fell all around, flashing in the lights. Bacteria coalesced into floc, carpeting the seafloor or being blown up into the megaplume, where they could be carried for miles, then sprinkle down like fake snow from an old Walmart Christmas tree.
‘Looks promising,’ Dave said. His arm twitched. The little sub tilted, and he corrected. ‘Poop.’
‘Focus,’ I said. The view outside was getting interesting. A thin, viscous silt covered the floor of the canyon. Ideal.
A long, segmented ribbon like a thick blade of grass floated in our
