The aircraft banked to the left, taking a northwesterly heading. Larson backed off on the throttles, commenting that you also had to pay close attention to engine temperatures here, though the cooling systems on the twin Continental engines were beefed up to allow for it. They were heading toward the country's mountainous spine. The sky was clear and the sun was bright.

"Beautiful, isn't it?"

"It is that," Clark agreed. The mountains were covered with emerald-green trees whose leaves shimmered with moisture from the night's rain. But Clark's trained eyes saw something else. Walking these hills would be a cast-iron bitch. About the only good thing to be said was that there was good cover under which people could conceal themselves. The combination of steep hills and thin air would make this place an arduous one. He hadn't been briefed on what exactly was going to happen, but he knew enough to be glad that the hard part of the job would not be his.

The mountain ranges in Colombia run on a southwest-to-northeast vector. Larson picked a convenient pass to fly over, but the winds off the nearby Pacific Ocean made the crossing bumpy.

"Get used to it. Winds are picking up today because of the weather front that's moving in. They really boil around these hills. You ought to see what real bad weather is like."

"Thanks, but no thanks! Not much in the way of places to land in case things -"

"Go bad?" Larson asked. "That's why I pay attention to the checklist. Besides, there are more little strips down there than you might imagine. Of course, you don't always get a welcome when you decide to use one. Don't sweat it. I just put new engines on this bird a month ago. Sold the old ones to one of my students for his old King Air. It belongs to the Bureau of Customs now," Larson explained.

"Did you have any part in that?"

"Negative! Look, they expect me to know why all these kids are taking lessons. I'm not supposed to be dumb, right? So I also teach them standard evasion tactics. You can read them in any decent book, and they expect me to be able to do that. Pablo wasn't real big on reading. Hell of a natural pilot, though. Too bad, really, he was a nice enough kid. They bagged him with fifty keys. I understand he didn't talk much. No surprise there. Gutsy little bastard."

"How well motivated are these folks?" Clark had seen lots of combat once, and he knew that the measure of an enemy is not to be found by counting his weapons.

Larson frowned at the sky. "Depends on what you mean. If you change the word from 'motivated' to 'macho,' that about covers it. You know, the cult of manliness, that sort of thing. Part of it's kinda admirable. These people have a funny sense of honor. For example, the ones I know socially treat me just fine. Their hospitality is impressive, especially if you show a little deference, which everyone does. Besides, I'm not a business rival. What I mean is, I know these people. I've taught a bunch of them to fly. If I had a money problem, I could probably go to them for help and get it. I'm talking like half a million in cash on a handshake - and I'd walk out of the hacienda with the cash in a briefcase. I'd have to make some courier flights to square things, of course. And I'd never have to pay the money back. On the other hand, if I screwed them, well, they'd make damned sure that I paid for that, too. They have rules. If you live by them, you're fairly safe. If not, you'd better have your bags packed."

"I know about the ruthlessness. What about the brains?"

"They're as smart as they have to be. What smarts they don't have, they buy. They can buy anything, anybody. Don't underestimate them. Their security systems are state-of-the-art, like what we put on ICBM silos - shit, maybe better than that. They're protected as tightly as we protect the President, except their shooters are less restrained by rules of engagement. I suppose the best indicator on how smart they are is the fact that they've banded together to form the cartel. They're smart enough to know that gang wars cost everybody, so they formed a loose alliance. It ain't perfect, but it works. People who try to break into the business mostly end up dead. Medell n is an easy town to die in."

"Cops? Courts?"

"The locals have tried. Lots of dead cops, lots of dead judges to prove it," Larson said with a shake of the head. "Takes a lot for people to keep plugging away when they can't see any results. Then toss in the money angle. How often can a man walk away from a suitcase full of tax-free hundred-dollar bills? Especially when the alternative is certain death for himself and his family. The cartel is smart, my friend, and it's patient, and it has all the resources it needs, and it's ruthless enough to scare a veteran Nazi. All in all, that's some enemy." Larson pointed to a gray smudge in the distance. "There's Medell n. Drugs 'R'Us, all in that one little city in the valley. One nuke could settle things, say about two megatons, air-burst four thousand feet AGL. I wonder if the rest of the country would really mind...?"

That earned Larson a glance from his passenger. Larson lived here, knew a lot of these people, and even liked some, as he'd just said. But his hatred for them occasionally peeked through his professional detachment. The best sort of duplicity. This kid had a real future in the Agency, Clark decided. Brains and passion both. If he knew how to maintain a proper balance of the two, he could go places. Clark reached into his bag for a camera and a pair of binoculars. His interest wasn't in the city itself.

"Nice places, aren't they?"

The drug chieftains were growing increasingly security-conscious. The hilltops around the city were all being cleared of trees. Clark counted over a dozen new homes already. Homes, he thought with a snort. Castles was more like it. Walled fortresses. Enormous dwelling structures surrounded by low walls, surrounded in turn by hundreds of yards of clear, steep slopes. What people found picturesque about Italian villages and Bavarian castles was always the elegant setting. Always on the top of a hill or mountain. You could easily imagine the work that went into such a beautiful place - clearing the trees, hauling the stone blocks up the slopes, and ending up with a commanding view of the countryside that extended for miles. But the castles and villages hadn't been built in such places for fun, and neither had these houses. The heights meant that no one could approach them unobserved. The cleared ground around those houses was known in terse military nomenclature as a killing zone, a clear field of fire for automatic weapons. Each house had a single road up to a single gate. Each house had a helipad for a fast evacuation. The wall around each was made of stone that would stop any bullet up to fifty caliber. His binoculars showed that immediately inside each wall was a gravel or concrete path for guards to walk. A company of trained infantrymen would have no easy time assaulting one of these haciendas. Maybe a helicopter assault, supported by mortars and gunships... Christ , Clark thought to himself, what am I thinking about ?

"What about house plans?"

"No problem. Three architectural firms have designed these places. Security isn't all that good there. Besides, I've been in that one for a party - just two weeks ago, as a matter of fact. I guess that's one area they're not too smart in. They like to show their places off. I can get you floor plans. The satellite overheads will show guard strength, vehicle garaging, all that sort of thing."

"They do." Clark smiled.

"Can you tell me exactly what you're here for?"

"Well, they want an evaluation of the physical characteristics of the terrain."

"I can see that. Hell, I could do that easy enough from memory." Larson's question was not so much curiosity as his slight offense at not being asked to do this job himself.
