Here's the thing. When I spoke to you last night, Max and I were with a woman named Tamara Wright

The one they kidnapped?

You've read the police report?

Just bits and pieces. They're taking it seriously, but there are no leads. The speedboat was discovered in Natchez, where a van was stolen from a plumber's house. The APB is out, but so far no hits.

I figured it would be something like that. They're smart. I bet that van will be found wherever they stole the cigarette boat. They'll have their own set of wheels back and could be just about anywhere.

Agreed. China? Overholt prompted.

Dr. Wright told us about a Chinese expedition in the late 1400s that sent a fleet of three ships to South America. Juan paused, expecting Overholt to question the validity of such a claim, but the wily case officer knew when to keep quiet. One of the ships was afflicted by a disease that drove the crewmen insane. Sound familiar?

The guy at Wilson/George, Langston breathed.

They ate tainted food provided by island natives. I think it was human flesh, most likely brain, and they got a dose of prions. The ship was scuttled with the crew aboard, and the remaining two ships ventured northward and eventually back to China.

Five hundred years later, along comes Andrew Gangle, who finds a mummy someplace near their base. It's carrying gold and jade. Somehow, he gets infected, most likely he accidentally stabbed himself on a shard of bone. Now he's got a prion disease rotting away his mind until he snaps and goes berserk.

That scuttled ship is off the coast of Antarctica? Dear God, Overholt exclaimed as he made the intuitive leap that Cabrillo had had the night before. If they can prove that Chinese explorers discovered Antarctica a couple hundred years before the first European, they . . .

Exactly, Juan said. They'll lay claim over it, or at least the peninsula. But with Argentina already so well entrenched, the smart move for them is to partner up and share the spoils. I believe this has been in the works for some time, long before we got involved. I think the Argentines were courting the Chinese because they would need the protection of a superpower and the patronage of someone in the UN. It was the chance discovery of that blimp and the subsequent events, like getting their hands on tangible proof that the Chinese had visited South America, that cemented the deal.

Do the Argentines or Chinese know the location of the third ship?

Not yet, but they'll be able to figure it out with enough research. Admiral Tsai's drawing was pretty specific. A good computer program and Google Earth should do it. But here's the thing: even if they don't find it, they can still claim the ship visited Antarctica. Who's to stop them?

We are.

What's the official White House position?

Events are unfolding too fast. They haven't said much, beyond the usual condemnation.

What does your gut tell you?

I honestly don't know. China currently holds the lion's share of our national debt, so they have us over a barrel in that respect. Also, logically, are we willing to go to war over a part of the world only a handful of people care about?

This is about principles, Juan pointed out. Do we stick to our ideals and risk lives for a bunch of penguins and a forty-year-old treaty or do we let them get away with it?

That's it in a nutshell, and I don't know what the President will do. Hell, I don't know how I feel. Part of me says to kick the bastards back to Beijing and Buenos Aires, but what's the point? Let them have the oil and the penguins. It's not worth putting our military personnel in harm's way.

Dicey call, Juan agreed, though in his mind the decision was a no-brainer. Argentina broke a binding international treaty by invading neighboring territory that didn't belong to them. They deserved the full wrath of the United States, and any other signatory to the Antarctic Treaty. He suddenly remembered something. Has NASA had a chance to analyze the power cell we recovered from their downed satellite?

Yes, and it is possible it was shot down, like your guy suggested, though they hedged and said the cause was indeterminate.

Why would they risk it? Cabrillo mused. Why, with everything at stake, would they take the chance and intentionally shoot down one of our birds?

If you want a real head-scratcher, it wasn't a spy satellite and was never rumored to be one. It was designed to monitor carbon dioxide emissions and was going to be used to make sure countries stay within their targets when and if a new treaty is implemented to replace the Kyoto Protocol.

Juan remained quiet for a moment, thinking. Of course, he said. They can hide the thermal signature of their Antarctic activities using sea water, but oil-and-gas exploration would produce a dense plume of carbon dioxide in a place that shouldn't have any. Once that satellite went active, we'd have known exactly what they were up to.

If they were going to annex the peninsula only a week after shooting down the satellite, why bother? Overholt asked.

You haven't been paying attention, Lang. The deal with China was only cemented in the last couple of days. Without that alliance, Argentina would need to keep their activities secret for months, maybe a year. China might have helped them shoot it down as a good-faith gesture or to guarantee they get the bulk of the crude that's pumped from those new wells. Either way, it shows they've been in bed together for a while.

I should have thought of that.

I've spent the last eighteen hours under police interrogation and I saw it, so, yeah, you should have. Juan was teasing, which at a time like this was an indication of the depths of his exhaustion.

What are your plans now?

I've got to make contact with the Oregon before I know where we're heading, but I'll keep you updated. Please do the same.

Talk to you soon.

Max had listened to Juan's end of the conversation. You don't know where we're going?

Juan pulled the microphone from his ear. Do you honestly think I'm going to trust the locals to find Tamara Wright? We got her into this mess and we're damned sure going to get her back out. I've rented the plane with the greatest endurance they have here, so we're going to get her no matter where she is.

That's why I love you. You'll spare no expense trying to get me a date.

Cabrillo grinned at Max's shamelessness and replaced the Bluetooth headset to call the Oregon. He asked Hali Kasim, their communications specialist, to patch him through to Eric Stone.

Why did you pull us off our search for the mystery bay? Eric asked.

Because you've already found it.

I have?

It's within snowcat distance of Wilson/George, maybe closer.

How could you know that?

Because I'm the Chairman. Juan really was exhausted. Do me a favor, I want you to check the logs of Jackson-Evers field for any private jets that flew out of here between, say, midnight and noon today.

In the pre-9/11 days, he probably could have charmed that information out of the pretty receptionist at the general-aviation counter, but not anymore.

Give me a second. Over the connection, he could hear Stone's fingers flying over his keyboard.

Juan was playing a hunch, one he felt reasonably certain about.

One last firewall, Eric said absently, then a triumphant, Got it. Okay, there were two. One was an Atlantic Aviation charter to New York City that left at nine o'clock this morning. The other was a private jet that filed a flight plan for Mexico City that took off at one-thirty this morning.

What can you tell me about that plane?

Hold on. That's another database. It took him less than a minute. The plane's owned by a company registered in the Cayman Islands.

A dummy front?

No doubt. It's going to take some time to . . . hold on a second. I'm checking its past flights. It arrived in the United States at Seattle-Tacoma International three days ago from Mexico City.
