Dark Matter

“Andy sweep house this morning before work,” she said. “Plugged all the mikes. Okay to talk now.”

I glanced at Rachel. The subtext was clear. Lu Li knew the score on Trinity, or at least she knew about the NSA’s security tactics. Geli Bauer would probably have this house torn apart as soon as Lu Li left for the cleaner’s or the grocery store. I was surprised she had waited even this long.

“Have you left the house at all today?” I asked.

“No,” Lu Li said. “They won’t tell me what hospital they take Andy to.”

I doubted Fielding had been taken to a hospital. He’d probably been flown to NSA headquarters at Fort Meade, Maryland, probably to some special medical unit for an autopsy, or worse. The British might complain later, but that would be the State Department’s problem, not the NSA’s. And the British—framers of the Official Secrets Act and the “D” notice—had a way of falling into line with the United States where national security was concerned.

“I still think we should whisper,” I said softly, pointing at the wand. “And I think I should take that box with me when I go. I’m afraid the N”— I stopped myself—“the company security people might search this house the first time you leave. You don’t want anybody to find it.”

Lu Li had been raised in a Communist country with ruthless security police. Her willingness to believe the worst was deeply ingrained. “Did they kill my Andy?” she whispered.

“I hope not. Given Andrew’s health, age, and habits, a stroke was possible. But … I don’t think it was a stroke. What makes you think he might have been murdered?”

Lu Li closed her eyes, squeezing tears out of them. “Andy knew something might happen to him. He tell me so.”

“Did he say this once? Or often?”

“Last two weeks, many times.”

I exhaled long and slowly. “Do you know why Andrew wanted to see me at Nags Head?”

“He want to talk to you. That all I know. Andy very scared about work. About Trinity. About …”

“What?”

“Godin.”

Somehow I had known it would be Godin. John Skow was easy to hate—an arrogant technocrat with no moral center—but he did not generate much fear. Godin, on the other hand, was easy to like—a genius, a patriot in the best sense of the word, a man of conviction—yet after you worked with him awhile, you sensed a disturbing vibration radiating from him, a Faustian hunger to know that disdained all limits, disregarded all boundaries. One thing was plain: anyone or anything that stood between Godin and his goal would not remain there long.

Godin and Fielding had got along well in the beginning. They were from roughly the same generation, and Godin possessed Robert Oppenheimer’s gift for motivating talented scientists: a combination of flattery and provocative insight. But the honeymoon had not lasted. For Godin, Trinity was a mission, and he pursued it with missionary zeal. Fielding was different. The Englishman did not believe that just because something was possible, it should be done. Nor did he believe that even a noble end justified all means to attain it.

“Did Andy have papers to show me?” I asked hopefully.

“I don’t think so. Every evening he make notes, but every night before bed”—she pointed to the fireplace—“he always burn them. Andy very secret. He always try to protect me. Always to protect me.”

He did the same for me, I thought. Suddenly, I remembered the words in Fielding’s letter. “Did Andrew take his pocket watch to work with him today?”

Lu Li didn’t hesitate. “He take it every day. You no see it today?”

“No. But I’m sure it will be returned to you with his personal effects.”

Her lower lip began to quiver, and I sensed another imminent wave of tears, but it didn’t come. Watching Lu Li’s stoicism, I felt a sharp pang of grief, familiar yet somehow new to me. I was no stranger to mourning, but what I felt now was different from what I’d felt after the loss of my wife and daughter. Andrew Fielding was one of the few men of his century who might have answered some of the fundamental questions of human existence. To know that such a mind had gone out of the world left me feeling hollow, as though my species were diminished in some profound and irrecoverable way.

“What will happen to me now?” Lu Li asked quietly. “They send me back to China?”

Not a chance, I thought. One reason Trinity was so secret was the belief held in some quarters that other countries might be at work on a similar device. With its history of aggressive technology theft, Communist China ranked high on that list. The NSA would never let a Chinese-born physicist who had been this close to the project return to her native land. In fact, I worried about her survival. But I could do little to protect her until I talked to the president.

“They can’t send you back,” I assured her. “Don’t worry about that.”

“Andy say the government do anything it want.”

I was about to answer when headlight beams shone through the foyer. A car was passing slowly by the house.

“That’s not true,” I said. “Lu Li, I don’t like saying this, but the best thing you can do right now is to cooperate with the NSA. The less trouble they see you making, the less they’ll perceive you as a threat. Do you understand?”

Her face tightened. “You say now I should let them kill my Andy and say nothing? Do nothing?”

“We don’t know that Andy was killed. And there’s very little you can personally do right now. I want you to leave everything to me. I’ve called the president, and I could hear back from him at any time. He’s in China now, of all places. Beijing.”

“I see on TV. Andy tell me you know this president.”

“I’ve met him. He was a friend of my brother’s, and he appointed me to my job. And I promise you that one way or another I’ll find the truth about Andrew’s death. I owe him that. And more.”

Lu Li suddenly smiled through her anguish. “Andy was good man. Kind, funny man. And smart.”

“Very smart,” I agreed, though words like smart meant little when applied to men like Andrew Fielding. Fielding had been a member of one of the smallest fraternities on the planet, those who truly understood the mysteries of quantum physics, a field reserved—as Fielding’s Cambridge students often joked—for those students who were “too smart to be doctors.”

Rachel squeaked in surprise as a white ball of fur raced into the room and leapt into Lu Li’s lap. The furball was a small dog, a bichon frise. Lu Li smiled and vigorously stroked the bichon’s neck.

“Maya, Maya,” she cooed, then murmured softly in singsong Cantonese.

The bichon seemed anxious at the presence of strangers, but it did not bark. Its little brown eyes locked on me.

“You know Maya, Dr. David?”

“Yes. We’ve met.”

“Andy buy her for me. Six weeks ago. Maya my baby. My baby until God blesses Andy and me with …”

As she lapsed into silence, I realized that my sixty-three-year-old friend had been trying to have a child with his forty-year-old wife.

“I’m sorry,” I said uselessly. “I’m so sorry.”

Rachel looked as though she wanted to speak, but there were times when even a gifted psychiatrist found herself at a loss for words. As Lu Li stared into space, my anxiety grew. If Fielding had suspected that he might be murdered, and he had voiced that fear to his wife, then the NSA might know he had done that. They almost certainly knew I was here now. If they were outside, they had probably photographed Rachel and would be trying to figure out what she was doing here.

“Maya looks like she could use a walk,” I said brightly.

Lu Li started from her trance.

“I’ll be glad to take her out for you,” I added.

“No. Maya no need—”

I cut her off with an upraised hand. “I think the air would do us all good.”

Lu Li stared at me for several moments. “Yes,” she said finally. “Is good idea. Me inside all day.”
