Low murmuring went around the room, but no one moved. “Okay, I’m going to assume that anyone here belongs here. If not, it’s your ass. Remember that.”

He turned back to Luke.

“The dam was built in 1943 to generate much-needed electricity during the war. It was built and is operated to this day by the Tennessee Valley Authority. For most of the dam’s life, the floodgates were operated by controls less sophisticated than your garage door opener. About twenty years ago, TVA started looking at ways to save money by automating their dams. Control centers in old hydroelectric dams are incredibly inefficient by modern standards. You’ve basically got people there around the clock, and their jobs include reading and writing logbooks, and opening and closing the spillways from time to time. The floodgates are almost never opened.

“TVA was thinking they could aggregate ten or twenty dam control centers into one centrally located control center. So they retro-fitted several dams with computer software that can be operated remotely. Black Rock was one of them. We’re talking about very simple software – yes means open the gates, no means close them. For one reason or another, they never did create the central control center, but they did make the software internet-based, in case they ever decided to do so. The final nail, so to speak, is that the science of encryption barely existed at that time, and the software has never been updated since it was first installed.”

Luke stared, stunned.

“You’re kidding.”

He shook his head.

“It was easy to hijack this system. It’s just that no one ever thought to do it before. What terrorist would even know this dam exists? It’s in a remote corner of a rural state. You don’t get a lot of style points for attacking Sargent, North Carolina. But as we’ve discovered, the results are as devastating as if they had attacked Chicago.”

Susan spoke for the first time during Kimball’s presentation. “And the worst thing about it is there are hundreds of dams like this across the United States. The truth is we don’t even know how many there are, and how many are vulnerable.”

“And why do we think the Chinese did it?” Luke said.

“Our own hackers at NSA traced the infiltration to a series of IP addresses in northern China. And we traced communication with those addresses to an internet account at a motel in Asheville, North Carolina, sixty miles east of the Black Rock Dam. The communications took place in the forty-eight hours before the attack. A SWAT team from the Bureau of Alcohol, Tobacco, and Firearms operates in that region, raiding unlicensed distilleries and breweries. That team was diverted to the motel, did a takedown of the room in question, and arrested a thirty-two-year-old Chinese national named Li Quiangguo.”

An image of a Chinese man being led from a small nondescript motel by a group of tall and broad ATF officers appeared on the screen. Another image appeared of the same man standing on a narrow roadway across from a lake. He stood in front of a historic plaque that read Black Rock Dam – 1943, with a couple of paragraphs of description below.

“Although he has travel documents including a passport under this name, we don’t believe this is the man’s real name. As you know, the sequence of names in China is reversed – the surname comes first, followed by the given name. Li is one of the most common surnames in China, practically a generic name, similar to Smith in the United States. And Quiangguo, in Mandarin Chinese, means Strong Nation. This was a name with militaristic connotations that was very common after the Chinese Revolution, but fell into disfavor probably forty years ago. Further, Li was found with a handgun in his possession, as well as a small vial of cyanide pills. We believe he is a Chinese government agent, operating under an alias, who was supposed to kill himself if he was about to get caught.”

“So he got cold feet,” Luke said.

“Either that, or he just didn’t get to the pills in time.”

Luke shook his head. “After an operation like this one, an agent willing to kill himself would be holding the pill bottle in his hand, or have it in his pocket, twenty-four hours a day. What were the communications?”

“They were a series of encrypted emails. We haven’t broken the encryption yet, and it may be weeks before we do. It’s one they haven’t seen at NSA. Very complex, very tough to take down. So at this moment, we have no idea what the content of the emails is.”

“Is the man talking?” Luke said.

Kimball shook his head. “He’s being held in a cabin at a FEMA detention center in northern Georgia, about ninety miles southeast of the attack site. He insists he’s simply a tourist who was in the wrong place at the wrong time.”

“That’s why we called you,” Susan said. “We’d like you to go have a chat with him. We thought he might speak to you.”

“Have a chat,” Luke said.

Susan shrugged. “Yes.”

“Get him to talk?”

“Yes.”

“For that, I’ll probably need my team with me,” Luke said.

A look passed between Susan, Kurt Kimball, and Kat Lopez.

“Perhaps we’d better discuss that in private,” Kimball said.

“Okay, Susan, so this is the part where you tell me again that the Special Response Team has been disbanded, right?”

“Luke…” she began.

They were sitting upstairs in Susan’s study. The study was just as Luke remembered it. A large rectangular room with hardwood floors and a white carpet in the middle. The carpet served as the focal point for a sitting area with big comfortable upright chairs and a coffee table.

One entire wall of the study was a floor-to-ceiling bookcase. The bookcase reminded Luke of The Great Gatsby.

And then there were the windows. Giant, gracious, floor to ceiling windows which gave expansive views of the Naval Observatory’s rolling grounds. The windows faced southwest and let in the afternoon light. The light was like something a master artist would try to capture.

The days were clearly getting shorter. Although it wasn’t yet 7 p.m., early evening sunlight streamed through her windows. The day was already ending. Luke thought again briefly of his interaction with Becca when he dropped Gunner off. He shook the image away. It was too much to think about.

He sat on the opposite side of the coffee table from the President. Kurt Kimball sat at an angle to both of them. Kat Lopez stood behind Susan and to her right.

“Yes,” Susan said. “There is no more Special Response Team. Most of the former staff have been absorbed into other roles within the FBI. At this point, it would be rather difficult to rebuild what you think of as your team.”

“Susan,” Luke said. “I’d like to remind you that you’re asking me to come out of retirement again. You know what I’ve been doing for the past two months? I’ll tell you. Camping, fishing, hiking, sailing. A little bit of hunting. A little bit of diving.” He rubbed his beard. “Sleeping late.”

“So you’re fit for duty,” Kurt Kimball said.

Luke shook his head. “I’m caked in rust. I need my team. I trust them. I can’t really function without them.”

“Luke, if you’d stuck around instead of disappearing, we might have been able to carve out a little agency for you…”

“I was trying to save my marriage,” he said.

Susan stared right at him. “How did it go?”

He gave her a tiny head shake. “Not too well, so far.”

“I’m sorry to hear that.”

“So am I.”

Susan glanced behind her. “Kat, can we have the status on Luke’s former team members?”

Kat Lopez glanced down at the tablet in her hand. “Sure. That’s easy enough. Mark Swann left the FBI for a job with the National Security Agency. He works at their headquarters here in suburban DC. He’s been there three and a half weeks. He’s moving through their classification system, and should begin work on the PRISM data mining project within another month.

“Edward Newsam is still with the FBI. He was out on medical leave for most of June and July. His hip rehabilitation is complete, and he’s been reassigned to the Hostage Rescue Team. He is currently in training at Quantico for possible overseas intelligence work to begin later in the year. There’s a note in his file that his employment status is likely to become classified in the coming weeks, at which point a Top Secret security clearance will be required to discuss his status or his whereabouts.”

Luke nodded. Neither of these were much of a surprise. Swann and Newsam were among the best at what they did. “Can we get them on loan?” he said.

Kat Lopez nodded. “In all likelihood, if we request them, the agencies will honor our request.”

“And Trudy?” Luke said. “I need her, too.”

“Luke, Trudy Wellington is in jail,” Susan said.

Luke felt his stomach drop at the words. He stared for a full five seconds, trying to process the words.

“What?” he finally said.

Susan shook her head.

“I can’t believe you don’t know. What have you been doing, hiding under a rock? Don’t you look at the newspapers?”

He shrugged. “I told you what I was doing. I’ve been off the grid. They don’t sell newspapers where I’ve been, and I’ve been leaving the computer at home.”

Kat Lopez read from her tablet. Her voice was automatic, almost robotic. She had detached herself from what she was saying.

“Trudy Wellington, age thirty, was Don Morris’s mistress for at least a year during the planning of the June sixth attacks. Email, telephone, text, and computer records suggest that as early as last March, she became aware of a plan to assassinate both the President and Vice President of the United States, and she was aware of who at least some of the conspirators were. She has been indicted on charges of treason, conspiracy to commit treason, more than three hundred counts of conspiracy to commit murder, and a host of other charges. She’s being held without bail at the Federal women’s prison facility in Randal, Maryland. If convicted of the charges against her, she faces penalties starting with multiple life sentences, up to and including the death penalty.”

Luke ran a hand through his hair. The news hit him like a punch in the head. He thought of Trudy, pictured her with her funny red glasses on, her eyes peeking over the top of her tablet computer. He thought of her on the night he went to her apartment at 3 a.m., opening the door with nothing on but a long, flimsy T-shirt, a gun in her hand. He thought of the two of them, and their bodies, together that night.

She was in prison? It couldn’t be real.

“Trudy Wellington is facing the death penalty?” he said.

“In a word, yes.”

“Basically, because she didn’t turn Don in?”

Susan shook her head. “It’s treason, no matter how you want to spin it. A lot of people died, including Thomas Hayes, who was both the President of the United States and a personal friend of mine. Wellington could possibly have prevented it, and chose not to. She chose to not even try. About the only way she can save herself at this point is to testify against the conspirators.”

“I have trouble believing that she knew,” Luke said. “Has she confessed?”

“She denies everything,” Kat Lopez said.

“I would tend to believe her,” Luke said.

Kat held out her tablet. “There’s about two hundred pages of evidence. We have access to most of it, which you can review. You might feel differently after you do.”

Luke shook his head. He looked at Susan. “So where does this leave us?”

She shrugged. “You can have Mark Swann and Ed Newsam for a couple days if you feel you need them. But you can’t have Trudy Wellington.”

She looked at him.

“And your chopper leaves in under an hour.”
