Black Rain

Danielle squinted against the sudden brightness, using a hand to shield her eyes. At the center of the clearing a gray stone pyramid towered above the flat, open ground. Its steep walls were smooth and unmarked on three sides, while a single stairway ran up its face to a small, square roof, fifteen stories above the forest floor.

A structure of unmistakably Mayan design, as perfect as could be—and yet, for reasons Danielle, and later McCarter, found hard to explain, it seemed out of place and foreign. Not only shouldn’t it have been there in the greater sense of all they knew about the Mayan race, but it shouldn’t have appeared as it did. It should have been buried in a tangled web of living trees, vines and soil, just as McCarter had been telling the group since day one. It should have been crumbling under the weight of its own stonework, failing and dilapidated as it drowned in the thickening rainforest and its ever-constricting grip.

But it was none of these things. It stood unencumbered and menacing, defiantly unbowed. It u

At the mere sight of it, the other members of the team began shouting, whooping and hollering in celebration and congratulating one another. Several of them began ru

They sprinted past, pausing briefly to congratulate her, before corralling McCarter and dragging him off with them, victorious.

Danielle let them go, preferring to savor the moment. As she walked farther into the clearing and its blissful daylight, she felt a great sense of accomplishment. At long last, she had something concrete to point to. The temple could not disappear like the other leads had. It could not turn out to be a sham or a hoax or a mistake in translation. It was tangible, concrete and irrefutable. She would find what they were looking for and she would return to Washington a hero.

CHAPTER 19

Matt Blundin sat in Stuart Gibbs’ office, aggravated and exhausted at the end of a seventeen-hour day. The director sat across from him, leaning back in his chair, head tilted upward, eyes staring blankly at the ceiling.

At 2:00 A.M. in Washington, Blundin had just finished explaining the nuances of a developing situation: a security breach and data theft that he’d only recently discovered.

Gibbs brought himself forward and exhaled loudly. “What else do you have?”

“That’s it,” Blundin said. “All we know right now is what happened.”

“I don’t give a shit about what happened,” Gibbs cursed. “I want to know how it happened, why it happened and who the fuck made it happen.” With the last phrase, Gibbs threw the report across the desk, where it fa

Blundin rubbed his neck. He was sweaty and grimy after such a long day and ready to lash out. But that would just make for a longer night. He plucked the report from his lap and placed it back on the desk, out of Gibbs’ reach, then pulled a dented pack of Marlboros from his breast pocket.

He drew one out and stuck it between his lips. Two flicks of the lighter and the tip was glowing red. Only after a long drag on the cigarette did he begin to reply.

“Look,” he said, white smoke billowing from his mouth. “I can tell you how it was probably done. I can even tell you when it was probably done, but that doesn’t help us with the who, because it could have been anybody on the network, either inside this building or out.”

Gibbs leaned back, looking pleased for the first time all night. “Let’s start with how.”

“Fine,” Blundin said. “We can start there, but we’re going to end up right back where we are now.” He exhaled another cloud of carcinogens and reached for an ashtray to lay the cigarette on. “It all starts with the codes. Our system uses a matrix code generated from a set of prime numbers and then exercised through a complex algorithm.”

Gibbs seemed lost already, which came as no surprise to Blundin. Maybe this was why he hadn’t listened in the first place.

Blundin leaned forward, demonstrating with his hands. “Just think of it like a combination lock. If you don’t know the combination you can eventually figure it out by checking every number against every other possible combination of numbers. You know, one, one, one, then one, one, two, then one, one, three—until eventually you get to thirty-six, twenty-six, thirty-six and it finally opens. Only in our case, we’re not talking about forty numbers or whatever you have on one of those locks, we’re talking about a massive set of possibilities.”

“How massive?”

“Try a one with seventeen zeroes after it,” Blundin said. “So many numbers that if you counted a thousand a second it would take you a hundred years just to count that high.”

Blundin eased back in his chair. “And that’s just to count them. To crack the code, each number would have to be checked against every other number, and then tested to see if it worked.”

By the look on his face, Gibbs seemed to understand. “What about the vendor, the manufacturer who sold us this encryption?”

“No,” Blundin said. “The illegal entries were made using an inactive master code reserved by the computer in case the system locks up.”

“What about an ex-employee?” Gibbs asked. “Someone who might know the system, but quit or got fired.”

“I already checked. No one higher than a receptionist has left Atlantic Safecom since we installed the system.”

“And here?”

“Every time one of our employees leaves, their code and profile are scrubbed from the system—and like I already said, it wasn’t an employee code, it was a master code.”

Gibbs pounded a fist on the desk. “Well, goddamnit, how the hell did they get the master code? That’s what I’m asking you. I mean, they didn’t fucking guess it, did they?”

“Actually,” Blundin said, “in a way, they did.”

Gibbs’ eyes narrowed, which Blundin took as a veiled threat that if he didn’t become more forthright, there would be repercussions.

“They made a lot of guesses,” Blundin said. “Over three hundred and fifty quadrillion.”

Gibbs’ face went blank. “That doesn’t even sound like a real fucking number.”

“It is,” Blundin assured him. “That’s what it takes to crack the code. That’s what I’ve been warning you about for the past year.”

Gibbs was silent, no doubt recalling Blundin’s requests to de-link from Research Division and his claims that the code could be vulnerable to a special type of computer-assisted probing. “The hacker problem,” Gibbs said finally. “Using a supercomputer or something. Is that how this was done?”

Blundin shifted in his chair. “Under normal circumstances, I would say no. Because even a supercomputer basically does things in series, checking one number against another, raising them by a single exponent and ru

Gibbs tapped his pen on the desktop. “You said ‘under normal circumstances.’ Am I to assume we’re firmly in the abnormal realm now?”

Blundin wiped his brow. “There’s a different type of programming out there,” he said. “In some cases, entering its third and fourth generation. It’s called massive parallel processing. It’s used to link computers together, everything from regular PCs to servers and mainframes. And it can turn those units into the equivalent of a supercomputer … or ten. Aside from NASA and the Defense Department, not too many people even use it, because no one needs that kind of power. But it’s out there and it’s faster than anything you can imagine.”
