"Helicopters?"

Duncan came to his feet at the same time Cavanaugh did. Followed by Chad and Roberto, they hurried with Tracy out of the kitchen, along a corridor, and into the control room.

Various television monitors were stacked in rows along a wall, receiving green-tinted night-vision images from cameras positioned around the helicopter and the bunker. But what the team focused its attention on was a radar screen, which showed three blips heading north, approaching the area.

Roberto studied them. "Yeah, the speed and the formation are consistent with helicopters."

"What's happening?" Prescott's strained voice asked behind them.

"We don't know yet," Cavanaugh said. "It might not be anything to concern us."

"The moment they appeared on the radar, heading up the Hudson," Tracy said, "it was obvious they were following the flight plan we filed at Teterboro."

"Coincidence?" Duncan asked.

"Maybe," Chad said. "There are a number of small airports up the Hudson, not to mention the one at Albany. They might land at one of them and go to a corporate retreat or something. Hell, maybe these are politicians flying to the state capital."

"Maybe," Tracy said. "And maybe not."

"What are we going to do?" Prescott asked.

No one turned from the radar.

"If it's Escobar's men trying to follow us," Roberto said, "the destination on the flight plan's too vague to bring them here. There are a lot of mountains and valleys. Even in daylight, those choppers could search forever and not find this place."

"Look." Tracy pointed toward the screen, where the three blips separated, moving west from the river.

"They're heading into the mountains," Chad said.

"Splitting up," Cavanaugh said, "saving time, searching one to a valley."

"But even with night-vision equipment, they're not going to see anything that tells them where we are," Roberto said. "For all they know, we landed at a farm and our helicopter's in a barn. It would take weeks for them to search all the farms in this area."

"Plus, if they flew here from Teterboro, they'll have to refuel in an hour or so," Cavanaugh said.

"Look." Tracy pointed again.

On the screen, the three blips moved back and forth over separate areas.

"Systematically searching," Duncan said.

"But they're doing it awfully fast," Cavanaugh said. "Even with night-vision equipment, they'd need to move slower to make sure they don't miss anything."

On the screen, the three blips shifted rapidly to three other areas.

"Holy… Nobody can do a visual check of a valley that fast, not even in daylight," Tracy said.

"Unless that's not how they're checking," Chad said.

"What do you mean?"

"Not visually."

The rest of the group abruptly understood what Chad meant. They swung to look at Prescott.

His pale face contrasted with his dark eyes, which were wide with apprehension as he, too, realized what was happening.

Cavanaugh stared back at the radar screen. "Infrared sensors? Thermal sensors?"

The blips moved swiftly to three other areas.

"Dies," Roberto said. "That explains it. They're looking for the helicopter's heat signature. The engine's cooled, but a thermal scanner makes metal look different from wood or dirt. They'll be able to distinguish the shape of the helicopter from the trees around it."

"Plus," Tracy said, "the landing pad'll still retain heat from the sunlight the concrete absorbed all day."

"But won't heat from the houses and farm equipment confuse them?" Prescott demanded.

"No," Duncan said. "A house or a truck would have an entirely different heat pattern. Besides, this valley's so rugged, there aren't any farms around here. The heat signature of the landing pad will be especially distinctive in the middle of a forest."

Prescott pushed through the group and stared at the radar. "How long before they get here?"

"At sufficient altitude, with magnifiers on the sensors, they can cover a lot of miles in a hurry. At the rate they're searching, they'll be here in ten minutes," Tracy said.

"This can't be," Duncan said.

"What do you mean, 'can't be'?" Prescott sounded more panicked. "It's happening right in front of your eyes!"

"Even with all his money, Escobar doesn't have the resources to suddenly get his hands on three helicopters with thermal sensors," Duncan said. "That's special equipment. You need to make plans to have it available, and Escobar had no reason to expect a helicopter chase."

"So where the hell did he get thermal sensors?" Chad asked. "It doesn't make sense. Unless…"

"What?" Roberto asked.

"Those aren't Escobar's men." Duncan swung again toward Prescott. "Is there anybody else you're afraid of? Who else would be chasing you?"

"Nobody. If those helicopters aren't Escobar's, I have no idea whose they could be."

On the radar, the blips moved relentlessly to three other areas, proceeding closer to the center of the screen, where the bunker and the helicopter were situated.

"Whoever they are, they're sophisticated," Duncan said. "What else do they have in those choppers?"

"Maybe it's time to worry about those rockets we talked about earlier," Chad said.

"Moment of truth," Tracy said. "We have to decide,"

"What's she talking about?" Prescott asked.

"Stay or go," Tracy said. "If we stay, we don't know whether they can blow their way in here. But if we go-"

"We can't leave by helicopter," Roberto said. "If they've got heat sensors, we have to assume they also have radar. They'll know if our chopper takes off."

"But what if Mr. Prescott isn't in it?" Duncan asked. "What if you take off and act as a decoy?"

"They still might shoot me down," Roberto said.

"No," Cavanaugh said, "they won't shoot. Not if they think Prescott's aboard. They want him alive. When they chased me on the highway, they could have shot me, but they didn't. They didn't want the car to crash and kill Prescott. It's safe for you to distract them."

"The rest of us could leave in the Jeep." Chad referred to one of two vehicles in the bunker's adjacent underground garage.

"Both Jeeps," Tracy said. "We could use one of the cars as another decoy. Some of the helicopters will scan for other heat signatures and follow us. They'll have to separate and go in three directions. If we can get to the highway-the New York State Thruway is twenty miles to the east-there'll be so much traffic, they won't be able to decide which car they're hunting."

On the radar, the blips kept moving toward the center of the screen.

The group stared at Duncan.

"If we go, they won't shoot at us because they want Mr.

Prescott alive. If we stay, they'll have him trapped. Does that about sum it up?" Duncan asked.

The group kept staring at him.

"Move," Duncan said.
