“David still exists.”
“In your memory. Not in the world.”
“He’s not dead.”
“He’s not alive, either.”
Vaughan said nothing. Just turned away and took a fine china mug from a cupboard and filled it with coffee from the machine. She handed the mug to Reacher and asked, “What was in Thurman’s little box?”
“You saw the box?”
“I was over the wall ten seconds after you. Did you really think I was going to wait in the car?”
“I didn’t see you.”
“That was the plan. But I saw you. I saw the whole thing.
Reacher nodded. “Fort Shaw, Oklahoma. An army base.”
“You fell for it.”
“I sure did.”
“You’re not as smart as you think.”
“I never claimed to be smart.”
“What was in the box?”
“A plastic jar.”
“What was in the jar?”
“Soot,” Reacher said. “People, after a fire. They scrape it off the metal.”
Vaughan sat down at her table.
“That’s terrible,” she said.
“Worse than terrible,” Reacher said. “Complicated.”
“How?”
Reacher sat down opposite her.
“You can breathe easy,” he said. “There are no wrecked Humvees at the plant. They go someplace else.”
“How do you know?”
“Because Humvees don’t burn like that. Mostly they bust open and people spill out.”
Vaughan nodded. “David wasn’t burned.”
Reacher said, “Only tanks burn like that. No way out of a burning tank. Soot is all that’s left.”
“I see.”
Reacher said nothing.
“But how is that complicated?” she asked.
“It’s the first in a series of conclusions. Like a logical chain reaction. We’re using main battle tanks over there. Which isn’t a huge surprise, I guess. But we’re losing some, which
Vaughan got up and walked over to her counter and picked up her glass of water. She emptied it in the sink and refilled it from a bottle in her refrigerator. Took a sip.
“I got a call this morning,” she said. “From the state lab. My tap water sample was very close to five parts per billion TCE. Borderline acceptable, but it’s going to get a lot worse if Thurman keeps on using as much of the stuff as he uses now.”
“He might stop,” Reacher said.
“Why would he?”
“That’s the final conclusion in the chain. We’re not there yet. And it’s only tentative.”
“So what was the second conclusion?”
“What does Thurman do with the wrecked tanks?”
“He recycles the steel.”
“Why would the Pentagon deploy MPs to guard recycled steel?”
“I don’t know.”
“The Pentagon wouldn’t. Nobody cares about steel. The MPs are there to guard something else.”
“Like what?”
“Only one possibility. A main battle tank’s front and side armor includes a thick layer of depleted uranium. It’s a byproduct from enriching natural uranium for nuclear reactors. It’s an incredibly strong and dense metal. Absolutely ideal for armor plate. So the second conclusion is that Thurman is a uranium specialist. And that’s what the MPs are there for. Because depleted uranium is toxic and somewhat radioactive. It’s the kind of thing you want to keep track of.”
“How toxic? How radioactive?”
“Tank crews don’t get sick from sitting behind it. But after a blast or an explosion, if it turns to dust or fragments or vapor, you can get very sick from breathing it, or by being hit by shrapnel made of it. That’s why they bring the wrecks back to the States. And that’s what the MPs are worried about, even here. Terrorists could steal it and break it up into small jagged pieces and pack them into an explosive device. It would make a perfect dirty bomb.”
“It’s heavy.”
“Incredibly.”
“They’d need a truck to steal it. Like you said.”
“A big truck.”
Reacher sipped his coffee and Vaughan sipped her water and said, “They’re cutting it up at the plant. With hammers and torches. That must make dust and fragments and vapor. No wonder everyone looks sick.”
Reacher nodded.
“The deputy died from it,” he said. “All those symptoms? Hair loss, nausea and vomiting, diarrhea, blisters, sores, dehydration, organ failure? That wasn’t old age or TCE. It was radiation poisoning.”
“Are you sure?”
