“Except it’s in the driest part of the desert,” Dirk said, “and the grade runs off kilter to the pattern we see.”
“So it’s camouflage,” Kurt said. “What are they hiding?”
“Our experts think they’ve moved a lot of earth,” Pitt said, “suggesting an underground compound of massive proportions. Infrared scans have detected an inordinate amount of heat coming from vents in the sand. All of which suggests manufacturing, though until now no one could guess what they were up to.”
“Stealing my design,” Marchetti said, “and going into production.”
Pitt nodded. “So it would seem. The question is, why?”
Marchetti considered this for a second. “I’m not sure,” he said. “I intended them to eat garbage, but from what we saw the design has been modified. Obviously that would imply a different purpose. At this point all we know for sure is that they attacked your catamaran, but unless I’ve missed something no other vessels have been attacked or gone missing. That would suggest it’s not their main purpose.”
“Then why use them for it?” Kurt asked.
Marchetti glanced at Leilani for a second and then spoke. “Under normal circumstances the boat would have been picked clean. Not a speck of organic matter would have remained. And the bots would have disappeared back into the sea.”
Kurt understood. “No evidence. No witnesses. The boat would have been found in perfect working order like the Mary Celeste. Only they didn’t count on the crew setting a fire to fight them off.”
“Exactly,” Marchetti said. “Without the residue you found, there would have been nothing to tell us what had happened. Even if another vessel had been watching from a distance, they would have seen nothing.”
Pitt returned the conversation to the original track. “So they can be a danger to shipping,” he noted, “but if that’s not their main function, what is? Could they be causing the temperature anomalies our team discovered?”
“Possibly,” Marchetti said. “I’m not sure how, but to some extent what they’re capable of depends on how many of them are out there.”
“Can you explain that?” Pitt asked.
“Think of them as insects. One isn’t a big problem—one wasp, one ant, one termite—not much of a threat. But if you get enough of them in the same place, they can cause all kinds of trouble. My design was capable of reproducing autonomously and spreading ad infinitum. That was the only way to make them effective. No reason to think these aren’t doing the same thing. Millions of them can cause problems for a small vessel, billions could pose a threat to a large vessel or oil platform or even something the size of Aqua-Terra, but trillions of them—or trillions of trillions—that could threaten the entire sea.”
“The entire sea?” Joe asked.
Marchetti nodded. “In a way, the microbots are a pollutant in their own right. Almost like a toxin. But because they’re active in feeding, reproducing and protecting themselves, it’s better to think of them as a nonnative species invading a new habitat. They all tend to follow the same trajectory. Without natural enemies, they start off as a curiosity, quickly become a nuisance and shortly thereafter become an ecosystem-threatening epidemic. Unchecked, the microbots could do the same thing.”
“I remember when the gypsy moths came to New England,” Paul said. “Nonnative. Arrived from China with no natural enemies. One year there were a few furry caterpillars. The next year they were abundant, and by the third year they were absolutely everywhere, by the billions, covering every tree, stripping every leaf and practically decimating the forests. Is that the kind of effect you’re talking about?”
Marchetti nodded glumly.
Quiet followed as the group pondered what Marchetti had said. Kurt imagined the microbots spreading through the Indian Ocean and around the world. He wondered if the thought was rational or paranoid and why someone would want that to occur or how they could profit from it.
“Whatever they’re doing, I think we can assume it’s not a good thing,” Pitt said. “Therefore we need to find out what it is and get on top of it. Any suggestions how we can do that?”
All eyes focused on Marchetti again.
“Two ways,” he said. “Either catch the microbots in the act, for which I offer my services and the island, or go to the source and see what their orders are.”
“Go to Yemen,” Pitt clarified.
Marchetti nodded. “I hate to say it, and I certainly wouldn’t want to ride along, but if these things are being manufactured in this underground compound in Yemen, your best chance of discovering what they’re being created for is to go to the factory and check out the specs.”
Pitt nodded thoughtfully but said nothing for the moment. He looked over the assembled team one by one.
“All right,” he said finally. “Our original goal was to find out what happened to the crew, but I think we can all agree that we’ve discovered a greater threat here. One they were probably killed for. We need to follow this up from both angles. Paul and Gamay will take advantage of Mr. Marchetti’s hospitality and head up the waterborne search, using Aqua-Terra as home base. Kurt, you and Joe get ready. Unless you have any objections, I’m going find a way to sneak you into Yemen.”
Kurt looked at Joe, who nodded. “We’ll be ready.”
Pitt signed off. The meeting adjourned, and everyone began to file out.
Leilani came up to Kurt. “I want to go with you,” she said.
Kurt continued gathering up his things. “Not a chance.”
