A vow is black and white. There's never a plausible excuse or justifiable reason to break it. You either keep a vow or break it. There's no middle ground. A vow is for ever.'
The sun had set and they were sitting round a small fire towards the top of the eye. They had had dinner and were now drinking coffee, arguing about the place in which they found themselves. Ross could sympathize with Hackett's view but earlier, when he'd shown Zeb the crystal concealed in his backpack and told her about his experience in the cave, she had sided with Sister Chantal. 'Ross, Lauren translated the Voynich. She deserves to be saved by the garden. In return, Sister Chantal will expect her to protect it. If Falcon and Sister Chantal believe that whoever translated the Voynich should determine what happens to this place they couldn't have chosen a more responsible person than Lauren. And I'll tell you now: the last thing Lauren would do is tell the world about it. Not until she knew what the world would do with it.'
Sister Chantal turned to the others. 'You will all honour the vow.' It was a command.
'Yes,' said Zeb, quickly.
Sister Chantal looked at Mendoza. 'And you?'
Mendoza met her gaze. 'People would pay anything to come to this place and be cured. But we have enough gold in the lost city. I'll keep my vow,' he said solemnly.
'But, Sister, why don't you want to tell the world about it?' pleaded Hackett. 'Think of the good it could do.'
'For whom?' said Zeb.
Hackett turned to her, surprised. 'For humanity, of course. This place will save lives.'
'But who will save this place?'
'What do you mean?'
'This place is a resource and not just for humanity. What do you think man would do with it if he found it?'
'Use it to heal, of course.'
'This small garden to heal the whole population of the Earth? Who chooses who to save first? Who takes priority before it's depleted and destroyed? And what do we do after we've exhausted it and killed all the living creatures here just to prolong our lives?'
'We could conserve it,' said Hackett.
Zeb laughed. 'The only thing mankind conserves are ruins – and I use the term mankind advisedly. We're crap at conserving living resources. Not until we've used them up or turned them into ruins. Only then, when it's too late, do we suddenly get all misty-eyed. Sister Chantal's right to keep this place secret.'
'But what if the pharmaceutical industry could analyse what's here?' demanded Hackett. 'We saw how important the spring water was to the lost city. It could contain stem-cell regenerators, electrolytes, amino acids. They could synthesize it. Make a limitless supply.'
Zeb laughed again. 'We also saw what happened to the lost city when the water dried up. Even if they could unlock this place's power, do you suppose the pharmaceutical industry – that paragon of ethics, morality and altruism – would give it away free?'
'They could make it affordable, at least.'
'Have you ever known any pharmaceutical company make anything affordable – particularly something as valuable as this – let alone give it away free? Just look at what's happening with HIV drugs in Africa. Even if they did give it away would that be a good thing? Think about it: a world with no more death or disease, just an ever- growing population, everyone needing their fix to keep them healthy and alive. Anyway, this place would put the pharmaceutical industry out of business overnight. They'd have to destroy it before it destroyed them.'
For all Zeb's pessimism, Ross feared she was right. If this was an alternative to oil he knew what his industry would do: exploit it or bury it.
Hackett was about to respond when Sister Chantal raised a hand, like a referee in a fight. 'Nothing in here can be synthesized,' she said. 'I had a sample analysed a few years ago and, apart from some amino acids and a low level of radioactivity, they found nothing. The synthesized version was useless.'
'They found nothing?' said Hackett. 'No stem-cell promoters? Nothing that might explain how it repairs DNA?'
The nun shook her head.
'I suspect that what drives life in this place is a precursor to DNA,' said Ross.
Hackett thought for a moment. 'You mean this whole place could be working on something like RNA? Or something even more primitive?'
'Whatever's the most primitive form of life,' said Ross. 'As a geologist the only way I can explain this place is if it's a throwback to when life first began on Earth. It may even be the place where life began. If DNA is like the Microsoft Windows software of life, then whatever's behind this garden is DOS or whatever came before that. This is the base programming behind DNA. The stuff that makes DNA. It might not exist anywhere else in the world. That's why labs can't detect it. They've never seen it before. They've no idea what they're looking for.'
Hackett was nodding. 'It seems as if every organism here has evolved different phenotypes from those in the outside world. Part of that could be environmental, due to its isolation, but a greater part could be that it stems directly from a more primitive genotype.'
'What the hell's the difference between a phenotype and a genotype?' asked Zeb.
'A genotype is an organism's genetic makeup, its book of instructions,' said Hackett. 'A phenotype is its physical form, what it looks like, determined by genes and environment. For example, your hair, skin and eye colour are largely determined by your genotype but expressed in your phenotype. The point is most creatures have evolved separate genotypes and phenotypes. The human genotype, for example, uses its phenotype to survive – by making our bodies want to have sex so we pass on our genes. But many evolutionary biologists believe that the first living organisms were so basic they were just bundles of instructions. The genotype was the phenotype. The software was the hardware. There was no secondary body. If life here is as primitive as Ross believes, then the base genotype, the original instructions for life, might still exist in its primal form, whatever that is.'
'This place can't be explained by science,' said Mendoza, solemnly. 'It's sacred. It's too important to be left to scientists or businessmen. Only the Church can know what's best for a place like this.'
'Which church?' said Sister Chantal.
Mendoza frowned disapprovingly. 'You're a Roman Catholic nun. There's only one church that can decide what's best for this place.'
Sister Chantal shook her head. 'A great man, a priest, once said that this place was the Garden of God and I believe him. It is sacred. Too sacred for any church or religion to control.' She gave a weary sigh. 'Let me tell you how this place was discovered and why my friends, Ross and Zeb, accompanied me here.' For the next few minutes she talked about Orlando Falcon, the Voynich, Lauren Kelly and Father General Leonardo Torino. Hackett and Mendoza listened, rapt, until she was finished.
But Mendoza was unconvinced. 'Sister, you'd rather entrust the future of this garden to a woman lying unconscious in hospital than to your own church?'
'Once Lauren Kelly has been cured I can hand over my burden. I'm simply fulfilling my vow. No more, no less. All I ask is that you fulfil yours.'
Hackett turned to Ross. 'You think the Father General could have been behind your wife's injury?'
'I've no proof, but I wouldn't put it past him after what happened with the bandits on the river.'
'But he's a senior officer of the Roman Catholic Church!' said Hackett.
'Then I guess they must really want this place.'
'So when do we leave?' asked Zeb.
'Tomorrow. We'll return first to the lost city.' Sister Chantal turned to Hackett and Mendoza. 'For your gold. Then Ross, Zeb and I shall go back to America.'
Hackett laid a hand on Ross's shoulder. 'We may have lost Juarez,' he said sadly, 'but it appears our trip into the jungle wasn't totally in vain. We all found what we were looking for.'
'Yes, I suppose we did.' But even as he said it, Ross thought of the light emanating from the tunnel of blood: the source. It was now clear that the garden and its unusual life forms were merely physical expressions of the miraculous powers that had drawn him here. The true source of the miraculous garden, and possibly life itself, was what Hackett had called the base genotype. And when he thought of its power and his desire to ensure Lauren's recovery, he realized that, despite the crystal in his bag, he might not have everything he had come for.
