“You spoke with a man today, in the cantina. What did you tell him?”
The question surprised Rodrigo almost as much as the fact that this woman masquerading as an ancient demon was speaking perfectly comprehensible Spanish.
“I… he wanted to buy relics from me. I told him nothing.”
“Why did he think you would be able to show him relics?”
“That is what I do. I look for things in the jungle.”
“What did you tell him?”
Rodrigo held nothing back. The story poured from his lips like another vomitous eruption — Diego’s discovery, the curse, the arrival of the soldiers in space suits, the death of the village and the fire that followed.
The woman listened intently for a while, but then silenced him with a slash of her hand. “Did you tell the man where to find el Guia?”
“I don’t understand—”
“The thing you call el Cadejo Negro.”
“No. I do not know where Diego hid it.”
Her eyes narrowed, as if stripping bare his soul. “You are lying.”
“No. I swear.”
She leaned closer until her face was just a few inches away. At the corner of his eye, he saw something moving.
The snake. It is alive after all.
The viper’s arrow-shaped head appeared between them, its forked tongue darting in and out of its mouth, probing the air.
“Tell me everything.”
“I did,” Rodrigo cried, tears streaming from his face.
“Then tell me again.”
“At the dawn of the twentieth century,” Alex began, “The world population was 1.6 billion. From 1800 to 1900, the increase was only about half a billion. One hundred years later, it was six billion. In 2011, we hit seven billion, and today, we’re over seven and a half. Developed nations have aging populations and low fertility rates, but the developing nations, the poorest countries where poverty is endemic and health care is virtually non-existent, have astronomically high birth rates. Conservative estimates predict that we will hit 10 billion before the end of the century.
“Ten billion people, Doug. Another three billion souls, fighting over resources that are already too scarce to meet our needs. It’s not sustainable.”
Simpson swallowed nervously. A sick feeling had taken root in his gut as Alex had ticked off the numbers. The conclusion he was driving at seemed inescapable. “Are you talking about… culling?”
Alex’s answer came a little too quickly. “Doug, we’re in the pharma business. That’s a decision for the politicians to make. But that’s not what I’m getting at.
“You’re a biologist, Doug. What happens when a species exceeds carrying capacity?”
“Uh, usually there’s a die-off. Too many consumers, not enough food. The population crashes.”
“Exactly. But something else can trigger a die-off, particularly when a species — like ours — becomes adept at altering its behavior in order to expand its food supply. It’s happened before. In the 14th Century, the Black Death wiped out sixty percent of the population in Europe. The disease spread quickly because populations were clustered together in cities and were interdependent because of trade and commercial specialization. Just like we are, only the population is larger by an order of magnitude. A pandemic disease agent like the Black Death would flash across the globe like wildfire today.”
“Except we can treat the plague.”
Alex nodded. “Yes. For now. But the increase in population brings with it an increasing chance of new drug-resistant strains of bacteria. Viruses, like influenza, mutate faster than our ability to develop vaccines. And fungal infections like the one we’re researching here may be the worst of all. Viruses and bacterial agents can be contained with quarantine management and sterilization, but fungal spores can be carried on the wind, or lie dormant for centuries. They’re like snakes sleeping in the grass.
“Are you familiar with chytridiomycosis? It’s a fungal disease that’s wreaking havoc in the global amphibian population. One hundred percent fatal in some species of frogs. Imagine if something like that becomes transmissible among human populations, and gets loose in Beijing or Mexico City. And fungal diseases often occur as secondary infections among people whose immune systems are compromised by AIDS or malnutrition.”
He waved a hand, dismissively. “I’m not telling you anything you don’t already know, of course. Finding the treatment for diseases that don’t yet exist is pretty much our mission statement. We’re heroes, fighting microbial monsters.”
Simpson swallowed again. “You said ‘Light and Shadow.’ That makes it sound like there’s a dark side.”
Alex returned a cold smile. “Actually, I said ‘Shadow and Light.’ You can’t have one without the other.”
He paused, as if to emphasize the point. “Shadow is what the ancient Maya called the fungal agent you are now researching. Maldición de la sombra—the Shadow Curse. At least that’s what Carina tells me.” He cocked his head sideways. “Did I introduce you to Carina? Fascinating woman.
“The Shadow all but wiped out the ancient Maya empire in the 10th Century. According to legend, two brave warriors found the cure in a cave somewhere. I believe that, if that cure had not been found, the Shadow would have consumed the world.”
“And you’ve got me messing around with it?” Simpson blurted. “A disease that could kill everyone? Do you even hear what you’re saying?”
Alex shook his head. “You’re missing the point, Doug. The important thing is that a cure can be found. Carina is off trying to find the cave with the cure, but we’re men of science. I have faith that you will beat her to it. Then, we will control both the Shadow and the cure — the Light.”
“Control?” Simpson said, incredulous.
“It’s just good business, Doug. When those Maya warriors returned with the cure, they were revered as gods. Why shouldn’t we at least see a little profit?”
“And that stuff about population? Why did you tell me that?”
“It’s like the old saying, ‘the cure may be worse than the disease.’ The Shadow has a role to play in the future of our species. It’s nature’s way of restoring the balance. If that balance isn’t restored, something much worse than the Shadow may be in the offing. Something we don’t have a cure for.”
“You said ‘control.’ The Shadow and the Light. You’re planning to unleash this disease on the world.” As soon as the words were out, Simpson regretted having spoken it aloud. If Alex was willing to decimate the world population, he surely would not hesitate to make one contrary scientist disappear.
But Alex merely shook his head. “What’s the profit in that? Besides, who am I to decide who lives or dies? No, I’ll probably put the Shadow on the open market. Someone will pay. Probably some lunatic tin pot dictator, like that tub of lard in North Korea. And once someone like that has it, everyone will want it. And they’ll want the cure, and we’ll be able to charge as much as we like.”
“Someone will use it,” Simpson said. “It will get out in the open, and people will die. Millions of people who can’t afford the cure.”
Alex shrugged. “Everybody dies eventually anyway. This way, there’s a chance to save the planet.” He paused a beat. “Don’t worry, Doug. Those loyal to me will of course be the first to be inoculated against the infection.”
He let the implications of that hang in the air between them. “I trust you will find the cure soon, but even if you don’t, Carina is close to finding the source. And I have another agent working on the problem as well. All the bases are covered. So I guess you have a choice to make, Doug. Shadow and Light? Or the darkness?”
