I drove on. I kept it at a steady fifty in the right lane. Everybody passed me. Nobody stayed behind me. I had no tail. I wasn’t sure if that was good or bad. The alternative might be worse. I passed the Kennebunk exit after twenty-nine minutes. Saw a rest area sign a mile later. It promised food and gas and restrooms seven miles ahead. The seven miles took me eight and a half minutes. Then there was a shallow ramp that swooped right and rose up a slope through a thicket of trees. The view wasn’t good. The leaves were small and new but there were so many of them that I couldn’t see much. The rest area itself was invisible to me. I let the truck coast and crested the rise and drove down into a perfectly standard interstate facility. It was just a wide road with diagonal parking slots on both sides and a small huddle of low brick buildings on the right. Beyond the buildings was a gas station. There were maybe a dozen cars parked close to the bathrooms. One of them was Susan Duffy’s Taurus. It was last in line on the left. She was standing next to it with Eliot at her side.
I drove slowly past her and made a wait gesture with my hand and parked four slots beyond her. I switched off the engine and sat gratefully in the sudden silence for a moment. I put the e-mail device back in my heel and laced my shoe. Then I tried to look like a normal person. I stretched my arms and opened the door and slid out and stumped around for a moment like a guy easing his cramped legs and relishing the fresh forest air. I turned a couple of complete circles and scanned the whole area and then stood still and kept my eyes on the ramp. Nobody came up it. I could hear light traffic out on the highway. It was close by and fairly loud, but the way it was all behind the trees made me feel private and isolated. I counted off seventy-two seconds, which represents a mile at fifty miles an hour. Nobody came up the ramp. And nobody follows at a distance of more than a mile. So I ran straight over to where Duffy and Eliot were waiting for me. He was in casual clothes and looked a little uneasy in them. She was in worn jeans and the same battered leather jacket I had seen before. She looked spectacular in them. Neither of them wasted any time on greetings, which I guess I was happy about.
“Where are you headed?” Eliot asked.
“ New London, Connecticut,” I said.
“What’s in the truck?”
“I don’t know.”
“No tail,” Duffy said, like a statement, not a question.
“Might be electronic,” I said.
“Where would it be?”
“In the back, if they’ve got any sense. Did you get the soldering iron?”
“Not yet,” she said. “It’s on its way. Why do we need it?”
“There’s a lead seal,” I said. “We need to be able to remake it.”
She glanced at the ramp, anxious. “Hard thing to get ahold of at short notice.”
“Let’s check the parts we can get to,” Eliot said. “While we’re waiting.”
We jogged back to the blue truck. I got down on the ground and took a look at the underside. It was all caked in ancient gray mud and streaked with leaking oil and fluid.
“It won’t be here,” I said. “They’d need a chisel to get close to the metal.”
Eliot found it inside the cab about fifteen seconds after he started looking. It was stuck to the foam on the bottom of the passenger’s seat with a little dot of hook-and-loop fastener. It was a tiny bare metal can a little bigger than a quarter and about half an inch thick. It trailed a thin eight-inch wire that was presumably the transmitting antenna. Eliot closed the whole thing into his fist and backed out of the cab fast and stared at the mouth of the ramp.
“What?” Duffy asked.
“This is weird,” he said. “Thing like this has a hearing-aid battery, nothing more. Low power, short range. Can’t be picked up beyond about two miles. So where’s the guy tracking it?”
The mouth of the ramp was empty. I had been the last guy up it. We stood there with our eyes watering in the cold wind, staring at nothing. Traffic hissed by behind the trees, but nothing came up the ramp.
“How long have you been here now?” Eliot asked.
“About four minutes,” I said. “Maybe five.”
“Makes no sense,” he said. “That puts the guy maybe four or five miles behind you. And he can’t hear this thing from four or five miles.”
“Maybe there’s no guy,” I said. “Maybe they trust me.”
“So why put this thing in there?”
“Maybe they didn’t. Maybe it’s been in there for years. Maybe they forgot all about it.”
“Too many maybes,” he said.
Duffy spun right and stared at the trees.
“They could have stopped on the highway shoulder,” she said. “You know, exactly level with where we are now.”
Eliot and I spun to our right and stared, too. It made good sense. It was no kind of clever surveillance technique to pull into a rest stop and park right next to your target.
“Let’s take a look,” I said.
There was a narrow strip of neat grass and then an equally narrow area where the highway people had tamed the edge of the woods with planted shrubs and bark chips. Then there were just trees. The highway had mown them down to the east and the rest area had leveled them to the west but in between was a forty-foot thicket that could have been growing there since the dawn of time. It was hard work getting through it. There were vines and scratchy brambles and low branches. But it was April. Getting through in July or August might have been impossible.
We stopped just before the trees petered out into lower growth. Beyond that was the flat grassy highway shoulder. We eased forward as far as we dared and craned left and right. There was nobody parked there. The shoulder was clear as far as we could see in both directions. Traffic was very light. Whole five-second intervals went by with no vehicles in view at all. Eliot shrugged like he didn’t understand it and we turned around and forced our way back.
“Makes no sense,” he said again.
“They’re short of manpower,” I said.
“No, they’re on Route One,” Duffy said. “They must be. It runs parallel with I-95 the whole way down the coast. From Portland, way down south. It’s probably less than two miles away most of the time.”
We turned east again, like we could see through the trees and spot a car idling on the shoulder of a distant parallel road.
“It’s how I’d do it,” Duffy said.
I nodded. It was a very plausible scenario. There would be technical disadvantages. With up to two miles of lateral displacement any slight fore-aft discrepancy due to traffic would make the signal drift in and out of range. But then, all they wanted to know was my general direction.
“It’s possible,” I said.
“No, it’s likely,” Eliot said. “Duffy’s right. It’s pure common sense. They want to stay out of your mirrors as long as they can.”
“Either way, we have to assume they’re there. How far does Route One stay close to I-95?”
“Forever,” Duffy said. “Way farther than New London, Connecticut. They split around Boston, but they come back together.”
“OK,” I said. Checked my watch. “I’ve been here about nine minutes now. Long enough for the bathroom and a cup of coffee. Time to put the electronics back on the road.”
I told Eliot to put the transmitter in his pocket and drive Duffy’s Taurus south at a steady fifty miles an hour. I told him I would catch him in the truck somewhere before New London. I figured I would worry about how to get the transmitter back in the right place later. Eliot took off and I was left alone with Duffy. We watched her car disappear south and then swiveled around north and watched the incoming ramp. I had an hour and one minute and I needed the soldering iron. Time ticking away.
“How is it up there?” Duffy asked.
“A nightmare,” I said. I told her about the eight-foot granite wall and the razor wire and the gate and the metal detectors on the doors and the room with no inside keyhole. I told her about Paulie.
