Дэвид Балдаччи - Hell's Corner

Which also meant they were always watching.

Now Stone closed his eyes again and envisioned the first bullet hitting several feet to his left. Then more rounds pounding the dirt. Pings and zings everywhere. He’d dropped to his belly. The Brit behind him had done the same. Friedman and Turkekul were already gone from the park. Padilla began the slow zigzag run for his life and ended up in the tree hole.

Boom.

Stone opened his eyes again and looked over at Chapman, who’d been standing there staring at him the whole time, her arms folded over her chest.

“Can they arrest you for not showing up for the hearing?” she asked.

“Probably,” said Stone in a clearly uninterested tone. “All the shots were on the western side of the park,” he said.

“Right, you mentioned that all the white tents were on the left side but didn’t explain what you meant by it.”

“That’s because I didn’t know what it meant. But why? Why were all the shots on that side?”

In response Chapman pointed to the government building. “Just the location of the shooter. It was a clear field of fire from there. They could see over the trees.”

“They could see over the trees on the right side too. They could fire through the tree canopy for that matter. Why did they need a clear field of fire? They obviously weren’t aiming at anyone.”

Chapman started to say something and then stopped.

“But that’s not the most important question,” he said.

“Okay, what is the most important question?” she asked.

“What was the test?”

She looked confused. “What test?”

“I think I know what Tom Gross was going to ask Steve Garchik. Garchik said bombers like to test their equipment, to make sure it works. I think Lafayette Park was the test. But what was tested? We originally thought the bomb was meant for another time, another event, but was accidentally triggered. Then we thought it might have been a test run. But those two hypotheses are incompatible. It’s either one or the other. Not both.”

Chapman started to say something again, but once more stopped.

“A test run? Like Garchik said, the bomb part always works. It’s the connections that fail. But would you risk detonating in Lafayette Park just to test your connections?”

“No,” said Chapman automatically. “They went to way too much trouble.”

“That’s right, way too much trouble.”

“So what then? You mentioned it was about the dogs. I’m assuming you meant the bomb sniffers.”

“I did. Where’s your laptop?”

Chapman pulled open her bag and slid it out. They walked over to a bench and sat down.

“Bring up the video from the night of the bombing,” he instructed.

She did so.

“Run the feed that happened before the gunfire started.”

Chapman pushed some keys and brought that image up.

“Hold it right there.”

She hit the pause button.

Stone rose and pointed to the northeast corner of the park. “Padilla entered the park at that spot.”

Chapman glanced down at the screen and then at where he was pointing. “That’s right.”

“Why that spot?”

“Why not that spot?”

“There are lots of places to enter the park. Remember Carmen Escalante said that her uncle was going to eat at a favorite restaurant on Sixteenth Street. That’s on the west side of the White House, not the east. If he were walking from Sixteenth Street he would have reached the west side of the park first, not the east. So why did he come in on the east side?”

“Maybe he went somewhere else. We never followed up on the restaurant where he actually ate. Or maybe he did eat there and then went somewhere else for a drink that was on the east side of the park.”

“Or maybe,” said Stone as he pointed at the screen. “Or maybe he had to enter the park on the east side because of that.”

Chapman looked where his finger was. “Because that’s where the police were stationed, you mean?”

“No, because that’s where the bomb dog was stationed. Run the video.”

Chapman hit the play button. Padilla walked within a foot of the dog. In fact it seemed as though he went out of his way to walk near the dog.

“But why would that matter? The dog didn’t do anything.”

“You’re a Brit. Ever read the Sherlock Holmes story entitled ‘Silver Blaze’?”

“Sorry, never got around to those.”

“Well, in that story Holmes was able to make much of the fact of the curious incident of the dog in the nighttime.”

“Why, what did the dog do?”

“Absolutely nothing. And as Holmes pointed out, that was the curious incident.”

“You’re only making me more confused.”

“The test, Mary, was to walk past that dog and not have it react. To have it do nothing, in fact.”

It took a moment, but the look on Chapman’s face turned to astonishment. “Are you saying that the bomb was on Padilla and not in the root ball?”

“Yes. A couple of pounds of Semtex would’ve caused the damage that occurred. He could’ve easily had that on his person.”

“But the leather bits from the basketball?”

“There was never any basketball. He had the leather bits already in his pocket. The tree farm, George Sykes, the hoop, John Kravitz — all were misdirection.” He added, “Carefully researched misdirection. When they discovered the tree was coming from Pennsylvania they also learned of Kravitz’s shady past.” He looked to the office building where the shots had come from. “And that explains why the gunfire was only on the west side. They couldn’t chance hitting Padilla. If the dog were on the right side, Padilla would have walked past it and then made his way to the east side. Because that’s where the hole was. Which was the other critical piece.”

“Are you saying he threw himself in that hole and then blew himself up?”

“The only plausible reason for him to run and throw himself in the hole in the first place was because it seemed that he was running for his life. The hole was in essence his foxhole. The gunfire was the catalyst. He would have no other reason to do it. That was why they needed to have the gunfire. To give him a reason to run and jump in that hole. Otherwise, if he simply detonated aboveground, we would all know the source of the explosive. Diving in the tree hole made us all look at the maple as being the source. Donohue told them when the hole would be covered. They had that one night to do it. Then we discovered all the planted evidence.”

“But hang on. Garchik said that dogs could never be fooled. How could Padilla get past that dog with a bomb on his person?”

“Garchik already told us. That was probably the other thing Gross wanted to ask him. What did Garchik tell us about smells?”

“That you couldn’t cover them up from a dog.”

“And he also said that smells were molecular . That’s the reason nothing can contain them. That’s why dogs can sniff out things locked in steel containers, covered in smelly fish and wrapped in miles of plastic.”

“Right.”

“And what did we learn about nanobots?”

“That they’re nasty buggers.” She paused, her jaw slowly descending. “And that they’re molecular too.”

“Exactly. They’re molecular too.”

“Are you saying that they used the nanobots to create a new type of explosive? The nineteen thousandth and first, if you will?”

“No. The ATF apparently found the usual type of explosive debris. Nothing revolutionary at all, which makes the whole thing even more brilliant. They used the nanobots to molecularly change the smell that traditional explosive materials give off. They would still make the thing go boom, but they wouldn’t smell like anything the dogs have been trained to ferret out. That’s how Padilla got past the dog. That was the test. Get past the dog’s nose with a bomb strapped right on your person. And they did it.”
