"Now I get it. You're here to fire me."

Her smile slipped a notch. "There's no need for drama. I'm trying to learn what I can about Dr. Fielding's situation."

"His situation? He's dead. Deceased. No longer with us."

"What did the two of you discuss outside work hours?"

"Soccer."

"Soccer?"

"Fielding called it football. He was 'football mad,' in his words. He followed Arsenal, an English team. It bored the hell out of me, but I liked talking to the guy."

"You're being disingenuous, Doctor."

"Am I?"

"Both you and Dr. Fielding opposed further work on this project."

"No. I had ethical concerns about one aspect of it. Fielding had other concerns."

"He wanted the project stopped."

"Only until the cause of the neurological side effects we're all experiencing could be determined."

"Did he discuss those side effects with anyone not cleared for Trinity information?"

"I have no idea."

"His wife, for example?"

I strained to keep my face impassive. "I can't imagine that he would."

Geli raised one eyebrow. "You spent nearly with her last night."

So they had been watching. Of course they had. They'd just killed Fielding, and they needed to see how his best friend would react. That meant they knew about Rachel.

"I made a condolence call."

"You discussed sensitive Trinity information with Lu Li Fielding. A Chinese physicist."

"I did nothing of the kind." I had thought Lu Li's mar¬riage to Fielding made her a British citizen, but I didn't want to get into that discussion now.

"Mrs. Fielding has vanished. We need to talk to her."

"Sounds like a personal problem."

Geli ignored my sarcasm. "If you helped her flee, you could be charged with treason."

"Has Lu Li committed a crime?"

Geli's face gave away nothing. "That has yet to be determined. She may be an accessory to treason."

The crystal, I thought suddenly. This has to be about Fielding's watch. "So both Fieldings are missing now. That's embarrassing, isn't it?"

Geli didn't look embarrassed. She looked unflappable.

"Last night Lu Li told me she'd received no word about her husband's body," I said. "She was very upset."

"That's not my area of responsibility."

"What about Fielding's personal effects? Lu Li partic¬ularly mentioned a gold pocket watch. An heirloom."

Geli pursed her lips, then shook her head. "I don't recall a pocket watch. But as soon as Mrs. Fielding turns up this will be sorted out."

I knew Geli was lying. She hadn't worked here for two years without seeing that watch a hundred times. "We're going to need a polygraph this morning," she said.

A cold sweat broke out on my trunk. "Sorry. I won't be taking one."

Her eyes narrowed. This was the first time I'd ever refused such a request. "Why is that?"

"I just lost a good friend. I didn't sleep well. I feel ter¬rible. My dog ate my homework."

"Dr. Tennant-"

"And I don't feel like submitting to your fascist bullshit today. Get it?"

She settled back in my chair and regarded me with increasing interest. "The employment agreement you signed permits polygraphs to be taken at any time. You've already agreed to submit."

The fear in my belly made me want to punch her in the face. I'd lived all my life with an extraordinary amount of freedom. As an internist, I'd owned and man¬aged my own practice. As an author I'd been limited only by my subject. But in the oppressive atmosphere of Trinity, I'd developed a kind of spiritual claustrophobia.

My father had experienced similar feelings when work¬ing on nuclear weapons at Los Alamos and Oak Ridge. And he'd submitted to his share of polygraph tests in his day. But times had changed since the Cold War. Today the NSA had lie detectors based on MRI technology, and unlike conventional polygraphs, they were accurate 100 percent of the time.

The principle was simple: it took more brain cells to lie than to tell the truth. Even a pathological liar first thought of the true answer when asked a question. Then he invented or recited his lie. That activity lit up a liar's brain like Christmas lights, and the MRI detected, imaged and recorded the result for his interrogators. It was Fielding who'd stopped the MRI polygraph tests, arguing that our strange symptoms could be aggravated by further MRI exposure. It was a victory in Fielding's war against the invasion of our privacy, but conven¬tional polygraph sessions were unnerving enough. Taking them on a surprise basis gave you the feeling you were living in an Orwellian dystopia, especially when you had something to hide.

"Are you going to sedate me?" I asked. "Tie me down?"

Geli looked as though she'd like to.

"No? Then forget it."

She raised a finger and idly touched her scar. "I don't understand why you're so combative, Doctor."

"Sure you do."

"You're hiding something."

"If I were, that would make two of us."

"You're trying to subvert this project."

"How could I do that? And why would I? The pro¬ject's already been suspended."

Geli studied her fingernails, two of which were gnawed to nubs. Maybe she wasn't unflappable after all. "By going public," she said finally.

There it was. The deepest fear of the paranoid mili¬tary mind. "I haven't done that."

"Are you considering it?"

"No."

"Have you spoken to the president?"

"In my life?"

Annoyance crept into her voice at last. "Since Dr. Fielding's death."

"No."

"But you left a message at the White House yesterday."

I felt my face flush.

"Yes."

"And you used a pay phone."

"Yes."

"Why?"

"The battery on my cell phone died." An easy lie, and impossible to check.

"Why not wait and call when you got home?"

"I was in the mood right then."

"In the mood to talk to the president of the United States?"

"That's right."

"About Dr. Fielding's death?"

"Among other things."

She seemed to weigh her next words carefully. "You told the White House you didn't want the other Trinity principals informed of your call."

My blood pressure dropped like a stone. How did they know what I'd said during that pay phone conversation? It had to be wiretapping surveillance, and not the local police or FBI variety. The NSA recorded millions of private tele¬phone calls every day, the disk drives in the basements of Fort Meade triggered by key words like plastique, Al Qaeda, strong encryption, RDX, or even Trinity. I recalled that I'd said "Trinity" as soon as the White House opera¬tor answered, to make her switch me to the proper contact. The NSA probably had a recording of my conversation from that point forward.

I drew myself up and looked Geli hard in the eyes. "I was personally appointed to this project by the president. Not by the NSA or John Skow or even Peter Godin. I'm here to evaluate ethical problems. If I determine that a problem exists, I report directly to the president. No or here has any say in the matter."

The gloves were off. I had just drawn a line between myself and everyone else in the Trinity building.

Geli leaned forward, her blue eyes challenging me. "How many cell phones do you own, Dr. Tennant?"

"One."

"Do you have others in your possession?"

Clarity settled in my mind like a resolving chord. They knew I'd called the White House, but they didn't know whether or not the president had gotten back to me. They had my phones covered-the ones they knew about-but they were worried about channels of communication they didn't know about. If they were wor¬ried about that, they had no inside line to the presi¬dent, and I still stood a chance of convincing him of my suspicions.

"Rachel Weiss owns a cell phone," Bauer said, her eyes alert for the slightest reaction on my part.

I took a slow breath and kept my voice even. "I don't know a doctor who doesn't."
