The Devil Colony (Sigma Force 7)
Page 115The entire basin detonated below them. It cracked like a dropped plate and blasted upward in bus-sized chunks that cleared twice the height of the canyon walls and came crashing down, stripping forested hills. At the same time steaming water rocketed upward, forming a geyser twenty yards wide and shooting a thousand feet into the air.
“Now that’s what I call a colonic!” Kowalski said.
The helicopter banked away, its pilot fearful of getting caught in the maelstrom of rock, water, and steam.
Chin watched. “That much heat should definitely have destroyed the nano-nest.”
Still, another question remained: Did the huge blast trigger the very thing they feared? Everyone held their breath as the helicopter circled, rising ever higher. The geyser continued to churn, but its fountain slowly began to recede. There was no evidence of magma rising or lava erupting.
After another minute, Chin let out a loud puff. “Looks like we’re okay.”
The helicopter spun farther out, heading away.
As they turned, Painter got a bird’s-eye view of the entire Yellowstone caldera. All across the basin, water was shooting high into the air, spiraling with steam.
“My God, it’s every geyser,” Chin said, amazed. “Every geyser’s erupting!”
As the helicopter raced across the dazzling display, Painter stared out in wonder at the dance of waters, the twinkle of steamy rainbows, suddenly deeply struck by the wonder of this world, this gift to mankind in all its resplendent natural beauty.
With his face pressed to the window, Kowalski looked equally impressed. “Next time, we should use more C4.”
June 1, 11:02 A.M.
Washington, D.C.
Gray took a cab straight from the airport to the National Archives. He’d taken a short nap on the flight from Columbia, Tennessee, after discovering all had gone well out in Yellowstone. He felt worlds better. Painter would be spending another day or two out there to make sure everything was okay and to make sure his niece was settled into her classes at Brigham Young University.
Back at the airport, he’d wanted to go with Monk to the hospital, to make sure they took good care of him after his gunshot wound, but Kat had called him as they were landing. Dr. Heisman, she said, had been able to decipher Meriwether Lewis’s coded message and wanted to share it right away. Kat offered to send someone else to the museum, but considering all the trouble and bloodshed involved in obtaining the buffalo hide and its message, Gray wanted to be the first to hear what it said.
He owed it to Monk.
He owed it to Meriwether Lewis.
So he said good-bye to Monk at the airport. His friend had been in good spirits. And for good reason. The private jet they’d flown had been stocked with an amazing selection of single-malt scotches. Kat would take Gray’s place at the hospital. And probably just as well. She would keep Monk from hassling his nurses too severely.
The cab slowed to the curb in front of the Archives. Seichan stretched next to him in the backseat.
“Here already,” she mumbled drowsily.
Gray caught the cabdriver staring at her in the rearview mirror as he paid the fare. He couldn’t blame the guy. She’d changed out of her blue coveralls and back into her leather jacket, her black jeans, and a gray T-shirt.
They reached the doors to find Heisman already waiting for them.
“There you both are,” he said by way of greeting. “Come. I have everything in the conference room. You didn’t bring the buffalo hide here by any chance? I would love to see it with my own eyes, rather than that photo you e-mailed.”
“I’m sure that can be arranged,” Gray said.
They entered the same conference room they had been in before to find it all cleaned up again. Only a few books dotted the table. Apparently, deciphering a centuries-old message required merely a couple of spare hours and the same number of books.
As they settled into the room, Gray asked, “How did you solve it so fast?”
“What? Meriwether’s final words? It wasn’t hard. The code that Meriwether used with Jefferson is well known. I’m sure they probably used more involved ones occasionally, but for most correspondence, they used a simple cipher. And considering that Meriwether was writing this as he lay dying, I suspect he went with the cipher he knew best.”
Gray pictured the man, shot twice—once in the gut, once in the head—struggling to leave this last message.
Heisman pushed and sent his chair rolling down the length of the table so he could grab a book. “I can show you. It’s a code based on the Vigenère cipher. It was used in Europe at the time and was considered unbreakable. The key to it is a secret password known only to the parties involved. Jefferson and Lewis always used the word artichokes.”
“Artichokes?”
“That’s right. The code itself involves a twenty-eight-column alphanumeric table to—”
He stood up, stepped toward the door, but pointed back to Seichan. “Dr. Heisman, why don’t you explain all about the cipher to my colleague? I’ll be right back.”
“I’d be happy to.”
Seichan just glared at him and rolled her eyes in exasperation as he left.
Out in the hall, the smile on Gray’s face faded as he read the number of voice mails on his phone. He’d been using the disposable for the past day and forgot to put his battery back into his personal phone until he hit ground again in D.C. Still, apparently it took over forty-five minutes to route and load the calls after he’d powered up.
He stared at the screen.
Maybe this is one of the reasons why it took so long.
He had received twenty-two messages over the past twelve hours, all from the same number. He kicked himself for not calling earlier. He remembered he’d gotten his mother’s first voice mail as they were fleeing Fort Knox. He’d had no time to listen to it then—and it had slipped his mind during all the commotion.
He started from the beginning, already feeling that familiar tension at the base of his spine. He held the phone to his ear.
“Gray, it’s your mother.” She started every phone call that way. Like I don’t know your voice, Mom. “It’s ten-thirty, and I wanted to let you know your father’s having a bad night. You don’t have to come over, but I thought you should know.”
