"You didn't see that?"

"What?"

"The guy up there pissing off the cliff!"

Her eyes went wide.

"He had a rifle."

"I didn't see anything! I was watching you. I thought you'd seen a snake or something."

"We're going back to the truck. Now."

Her face had lost its color. "What about the cave?"

"It's blown. They're waiting for us up there."

"They can't be."

"They are. The guy was carrying an Ml6 and wear¬ing body armor. Deer hunters around here look a little different."

"But we've come all this way."

Prickly heat covered my skin. "What do you care?"

"I don't. I mean-that cave just sounded safe."

"It's not."

A new awareness smoldered in the dark of my mind. They knew we were coming. Before my thoughts could go further, I found myself listening with absolute concen¬tration. I wasn't sure what I'd heard, but it was some¬thing. A movement that didn't fit the usual sound track of the forest. I cursed silently. The rain that had damp¬ened the sound of our steps was now giving cover to our enemies. Or were they only my enemies?

As understanding flashed into my mind, another faint squawk broke the silence, and I knew there was another rifleman within fifty feet of me. Stepping quietly behind Rachel, I clapped one hand over her mouth and whipped my other arm around her chest, pinning her against me with all my strength. She tried to scream, but no sound passed her lips.

I stood in the creek without moving, water pulling at my legs. Rachel struggled against me. The backpack made it hard to hold her. I was afraid she might bite my hand, but she didn't. That alone kept alive doubt that it was she who had told the NSA where to find us.

"I'm going to uncover your mouth," I whispered. "If you scream, I'll cut your throat."

CHAPTER 21

When I let go of Rachel, she whirled in the creek, her face a mask of terror and fury. Then she saw the knife in my hand, the Gerber I'd bought at Wal-Mart.

"Walk," I told her. "Back down the creek. You know how to do it."

She stared at me a moment longer, then turned and started over the rocks. I sheathed my knife and unslung my bow. I would stand little chance against a man with an Ml6, but if I saw my opponent first, I might get off a quick shot.

"Stick close to the right wall."

She moved to the right, quickly picking her way from stone to stone. As I followed Rachel down the steep watercourse, my mind filled with questions I should have asked her before but hadn't. That first day, when she'd awakened me from my dream about Fielding's death… how had she unlocked the door? I'd locked it after the FedEx man left, yet I'd awakened to find the door banging against the chain latch as Rachel yelled my name. And finding my house without me telling her my address? I know someone in the UVA personnel office, she'd said. The university would have been warned about giving out information on a Trinity principal. And the surveillance plane over the highway? How had they known which of the thousands of cars between Chapel Hill and Nags Head to train their laser on? One phone call from Rachel while I was unconscious could have given them the Audi, the Nags Head cabin, everything.

As for Oak Ridge, she could easily have called them from the Wal-Mart in Asheville, when I'd posted her by the door. She hadn't known about Frozen Head then, but she did have a cell phone. With a little nerve, she could have called the NSA when she got out of the truck last night to pee. On the other hand, I still remembered leaping into the hallway of my house and finding an assassin pointing a gun at Rachel's back.

She paused as she came to a deep channel in the creek. I moved close behind her in case she fell or tried to run. As we negotiated the channel, I thought back to how I'd chosen her. Skow had resisted my going to a non-NSA psychiatrist, but had he resisted vigorously enough? Friends at UVA had told me Rachel was the best Jungian analyst in the country. Had Geli Bauer been walking in my footsteps, talking to everyone I talked to? Had she briefed Rachel before my first appointment? How could Geli have compromised her? An appeal to patriotism? Blackmail? There was no way to know.

I reached out and grabbed Rachel's pack. The creek had leveled out. The road wasn't far away.

"We're close to the truck," I said softly. "Veer left here, and don't step on any branches."

She looked back at me, her eyes still furious. "You don't really think-"

I poked her in the back. "Walk."

She picked her path through the dripping trees with surprising agility. After about forty yards, I grabbed her pack again, then scanned the trees ahead.

"David, you don't think I betrayed you."

I nodded. "No other explanation."

"There has to be."

I peered between the wet trunks, searching for any¬thing out of place. "They might have figured out Oak Ridge, but not Frozen Head. I could have picked a dozen other spots in the mountains around here."

She held up her hands helplessly. "I don't know what to tell you. I haven't spoken to anyone."

"How did you get into my house that day? The first day?"

"Your house? I picked the lock."

"Bullshit."

"You think so? My father was a locksmith in Brooklyn. I grew up around the trade."

Her explanation could be a facile lie, but it had the outrageous ring of truth. "What's a Chubb?" I asked off the top of my head.

"A high-quality, British-made lock. I also know what a spiral tooth extractor is. Do you?"

I had no idea. "Turn around and keep walking. The truck's a hundred yards ahead."

Rachel turned and walked quickly through the trees. With my bow unslung, I had to be more careful. The bowstring seemed to attract briers, and the broadhead I was holding along the shaft of the bow kept catching on branches and shaking water onto me.

Suddenly, I heard a swish like a big buck leaping through wet foliage. Then I saw a flash of black between two trees.

"Freeze!" barked a male voice.

Rachel stopped, her back just visible between two glistening trunks. Beyond her stood a man wearing black nylon and a bulletproof vest. He held an automatic pis¬tol, and it was trained on Rachel's face.

"Where is he?" asked the gunman.

"Who?"

"You know. The doctor."

I nocked the arrow and slowly raised my bow.

"I don't know what you're talking about," Rachel said. "I'm out here shooting a wildlife spread on deer."

The lie sounded effortless. Was she signaling the gun¬man with her hand?

"Where's your camera?"

I pulled the bowstring to full draw against my right cheek and peered through the peep sight. Rachel's body partially blocked my shot, and I didn't want to shift my weight for fear of making noise.

"I lost it in the creek," she said. "Are you a game warden?"

"Red Six to Red Leader," the gunman said into his collar radio.

"I'll tell you!" cried Rachel.

I leaned to my right, straining for a shot.

The gunman looked up from his radio. "All right. Where is he?"

Some bulletproof vests will stop a bullet but not a knife point. A razor-sharp broadhead should pierce what a knife would, but if it didn't, Rachel's face-or mine- would disappear in a cloud of red mist. I aimed for the V of the gunman's throat, just above the top of his vest.

"What will you do if you find him?" Rachel asked.

"That's not your problem."

"Red Six," crackled the radio receiver in the man's ear, loud enough for us to hear. "This is Red Leader. Repeat your message."

As he reached up to key his radio, Rachel screamed my name, and I loosed the arrow.

Rachel's scream masked any sound of impact. For a moment I was afraid I'd hit her. She'd fallen to her knees, but the gunman was still standing and holding his pistol. Why hadn't he fired? Had my arrow passed him without a sound? My bowstring was silenced. I jerked another arrow from my quiver and tried to nock it with shaking fingers.
