“Can’t say that, no,” admitted Gross. “But because of the geographic proximity and the PM’s presence.”

“Right,” said Stone. “Have you seen the surveillance video of the park from last night?”

“Got it all set up at the mobile command post. Unfortunately, the damn cameras were knocked out by the blast. Surprised about that, because there’s about a dozen recorders stationed all around here and manned by probably five different agencies. The bomb might have been designed to jam them, though, for some reason.”

Stone’s face was inscrutable at this comment. The FBI had clearly not been privy to the unedited video. Stone filed that one away for now. “Source of the gunfire?” he asked.

Gross pointed to the northern end of the park. “Rooftop garden of the Hay-Adams Hotel. We found lots of shell casings. TEC-9 rounds.”

“Interesting choice of weapon,” said Stone.

“Why?” asked Gross.

“Limited range. About twenty-five useful meters. Which is shorter than the height they were firing down from. And it’s hard to hit anything with a TEC-9 that’s not standing right in front of you.”

“Well, they
didn’t
hit anything.”

“But you found no guns?” Stone asked.

Gross shook his head.

“How was that possible?” asked Chapman. “Do people just walk around in the States carrying machine guns? I thought the British press was making that up.”

“Not sure yet. And no, people do not walk around here carrying machine guns,” Gross added indignantly. “The hotel folks are
cooperating fully. The garden is popular but not incredibly secure. Of course we shut the hotel down until the investigation is over. We kept all the guests on premises and are interviewing them right now.”

Stone asked, “Were the guns set up remotely or were human fingers pulling the triggers?”

“If they were operated remotely all traces were removed. For now I think we have to assume human involvement.”

“You said you locked the hotel down?” Stone said.

“Yes, but there was a time gap,” Gross conceded.

“How long?”

“It was pretty much chaos down here for a couple hours. When the source of the gunfire was confirmed, that was when the lockdown was set up.”

“So, easily enough time for the gunners to slip out, taking their hardware with them?”

“Multiple machine guns wouldn’t be exactly inconspicuous,” Gross pointed out.

Stone shook his head. “If you know what you’re doing you can break down a TEC-9 very quickly and fit it inside a briefcase.”

“We shut things down as fast as we could. But it is what it is.”

“Hopefully, someone at the hotel will remember seeing people leaving, perhaps with a bulky case?” noted Chapman.

Gross didn’t look too confident. “An event they had there was just letting out. Lots of people with briefcases leaving about that time, apparently.”

“That wasn’t a coincidence,” said Stone. “That was good prep work.”

A guy in a hazmat suit walked over to them. He tugged off his head covering. He was introduced as an agent from the ATF, Stephen Garchik.

Gross said, “Good to go?”

Garchik nodded and grinned. “Nothing that’ll kill you.”

Stone looked at the tent markers. They were divided between orange and white. The orange were far more numerous and were spread out relatively evenly around the park. The white markers were almost all on the western side of the park.

“Orange is bomb debris and white are locations of found slugs?” Stone ventured.

Garchik nodded approvingly. “Yep, obviously there were far more bomb bits than bullets, emanating from the blast seat.”

“What kind of explosive device was it, Agent Garchik?” Stone asked.

“Just make it Steve. Too early to tell. But by the size of the debris field and damage to that statue, it was some powerful stuff.”

“C-4, or Semtex maybe?” asked Chapman. “They can both do serious damage in relatively small footprints.”

Garchik said, “Well, this is a lot of damage for a stick of TNT or even a pound of Semtex. Maybe it was a cocktail of components. Maybe HMX or CL-20. That stuff is scary powerful. They’re all in the family of most potent non-nuclear high explosives. But it most likely wasn’t military ordnance.”

“How do you know that?” asked Stone.

Chapman answered. “White smoke on the video. Military grade is oil-based, leaving a black smoke trail. White is usually commercial.”

The ATF agent smiled appreciatively. “You know your stuff. We’re bagging and tagging now. Taking residue from the blast seat.” He pointed at two burly black Labradors being walked around the grounds by their handlers. “Roy and Wilbur,” he said. “Those are the dogs’ names,” he added. “Dogs are the cheapest, most reliable bomb detectors in the world. One of my dogs can screen an entire airport in a couple hours. So they’ll burn through this whole park in no time. Find bomb residue my guys won’t even be able to see with all our fancy technology.”

“Impressive,” said Chapman.

Garchik continued with enthusiasm. “There aren’t even any machines in existence that can measure accurately the power of a dog’s nose. But I can tell you that people have about 125 million smelling cells in their nasal passages. Our Labs have twice that. We’ll run all the evidence up to our Fire Research Center in Maryland. We can torch a three-story building up there and have a hood large enough to capture every molecule of the burn-off. Be able to tell you exactly what was used.”

Stone said, “Anything left of the guy in the hole?”

Garchik nodded. “Bombs throw debris three hundred and sixty degrees. We’ve pulled body parts out of tree canopies, off surrounding rooftops. Two, three blocks away. Found a piece of a foot on the White House lawn. A partial index finger on the roof of St. John’s Church. Then there was tissue, brain matter, the usual stuff. DNA field day. Guy’s on a database somewhere we’ll know soon enough.” He nodded at the NRT truck. “Of course, the first thing we did was shut down the area and send in our dogs.”

“Secondary strikes,” noted Chapman.

“Right. They’ve made that a fine art in Iraq and Afghanistan. Trigger off a bomb, everybody rushes in to help, and they pop the secondary strike to take out the first responders. But we found nothing.” Garchik added in a proud tone, “And our Labs are exceptional. They’re mostly service-dog-school dropouts that can sniff out nineteen thousand different explosives based on the five major explosive groups, including chemical compounds. We train them with food. Labs are land sharks, do anything for food.”

“They can never be fooled?” asked Chapman.

“Let me put it this way. Roy over there found a four-inch-square C-4 block that was covered in dirty diapers and coffee, packed in Mylar bags in cement-lined crates, sealed in foam and locked in a storage room. And he did it in about thirty seconds.”

“How is that possible?” asked Chapman.

“Smells occur at the molecular level. You can’t seal them up, no matter how hard you try. Plastics, metals, pretty much any container or cover-up method can’t trap molecules because those materials are still permeable. They can hold solids and liquids, and even gases, but smell molecules are something altogether different. They can pass right through those substances. If the detection method is sensitive enough it really doesn’t matter what the bad guys do. Trained bomb detection canines have an olfactory capacity that is humanly impossible to fool, and believe me, lots of people have tried.”

“How do you think this bomb was detonated?” asked Gross.

The ATF agent shrugged. “Basic rule of three. To make a bomb you have to have a switch, power source and the explosive. Bombs
are just basically something that can violently expand at extremely fast speeds while trapped in a confined space. You can detonate a bomb any number of ways, but the basic two are via a timer and by what we call command detonation.”

Chapman said, “Meaning the person doing the detonation is present?”

“Either the bomber or someone else. And the ‘someone else’ is usually to safeguard against the bomber getting cold feet. Probably half the suicide bombings in Iraq are detonated by third parties for that very reason.”

“I take it you’ve been there,” said Gross.

Garchik nodded. “Four times. And to be frank, I hope I don’t have to go back.”

“So
where
was the bomb?” asked Stone. “On the blown-up jogger?”

“Nope, don’t think that’s possible,” said Garchik.

“Why?” asked Stone.

“He went to the dogs.”

“What?” said Gross.

“I’ll show you. Come on.”

CHAPTER 17

to the ATF’s command unit. Inside he fired up an array of electronic equipment. Moments later they were watching some of the video feed from the night before. When a particular scene came up he froze it and pointed his finger at the screen.

“There. Like I said, he went to the dogs. Or
dog,
in this case.”

The image was of the man in the jogging suit. He was entering the park from the north. He was frozen right next to two uniformed officers, one of whom had a dog. The jogger was perhaps a foot from the canine.

Chapman said, “Is that a bomb detection canine?”

“Yes, it is. Secret Service’s. Now, I don’t think their dogs are better than ours, but I can tell you any person carrying an explosive walking that close to a bomb detection canine trained in this country is gonna get busted. I don’t care how he tried to hide it. That dog would be going nuts or else doing a passive alert, meaning he’ll sit right down on his butt. This dog was doing neither.”

“And you’d think if he was carrying a bomb on his person he wouldn’t have walked right next to the dog in the first place,” said Stone. “He couldn’t assume it wasn’t a bomb sniffer.”

Gross added, “Which means this wasn’t a suicide bomber. The guy jumped into the hole to avoid the gunfire. Looks like the bomb was in that hole.”

“Well, that’s progress anyway,” said Stone. “Ruling out the jogger.”

“Was it a pressure switch?” suggested Chapman. “Jogger hit it and boom.”

“That’s possible,” conceded Garchik, though he didn’t look convinced. “Accidental detonation, you mean.”

“Maybe. Did you find any evidence of another type detonation switch?”

“There’s a million pieces of stuff lying around here and we’re still looking. But to complicate matters a bit, Lafayette Park is home to a lot of static electricity.”

“And static electricity can set off a bomb,” said Chapman.

“That’s right.”

“But if you go to all the trouble to get a bomb into Lafayette Park, why would you build the bomb in such a way that it might trigger off accidentally?” asked Gross.

Garchik said, “Might be as simple as the folks who managed to get the bomb in here were better than the guy building the bomb. That’s not as implausible as you might think. Or it could have been on a frequency switch and something interfered with it.”

“The jogger was wearing an iPod,” Gross pointed out. “That could have interfered.”

“That’s possible, yes.”

“But are we really sure the tree hole was the source of the bomb?” asked Chapman. “We’re sort of jumping to conclusions here that it was.”

“We haven’t finished our analysis, but it’s a safe bet that was the bomb seat,” said Garchik.

Stone said, “Then are we sure that the bomb going off was an accident?”

They all looked at him curiously.

Gross said, “It had to be. Otherwise why would they set off a bomb that had no chance of killing the prime minister?”

“Unless it was set on a timer,” said Chapman. “The PM was supposed to be in the park last night. If it was set on a timer there’s no way to take that back.”

“And it was a coincidence that the man jumped in the hole and it went off when it did,” added Garchik. “That works.”

“No, it doesn’t work,” countered Stone. “You’re forgetting the gunfire. Why have both the gunfire and the bomb? And if the
gunfire wasn’t done remotely, then the shooters would’ve known the prime minister wasn’t in the park.”

“That’s not necessarily true,” said Chapman. “I’ll show you.”

She led them back outside, where she pointed to the trees in front of the Hay-Adams Hotel. “If they were on the rooftop garden back there then the trees would’ve hidden the park from their view. They hear the sirens and the motorcade coming. They wait for it to pull in, the prime minister to get out and walk to the park. Then they start shooting.”

Stone did not look convinced. “So you’re saying this elaborate plan was put together and the gunners were firing blind?” He shook his head. “If I were going to do this, at the very least I’d have one spotter with a clear view of the PM’s movements stationed somewhere near the park with a secure line of communication. I’m not shooting blindly through tree canopies. And if the PM doesn’t come to the park, I call off the mission. But if he does set foot in the park I can’t afford to miss.”

“And they did miss everyone,” Gross pointed out.

The ATF agent nodded. “It’s a puzzler all right.”

Stone turned to him. “So if you were going to pull off this bombing, how would you detonate, Steve?”
