"Glad to hear she's okay. She may be our only hope."

Austin was struck by the seriousness in Trout's voice. He sat up on the edge of the bunk.

"Our only hope for what, Paul?"

"Gamay and I found a copy of the Kovacs Theorems in Los Alamos. I did a computer simulation based on the Kovacs stuff and existing material on polar reversal. The situation doesn't look good."

"I'm listening." Austin was fully awake now.

Trout paused. "The simulation showed that the magnetic polar reversal is not as elastic as some people think. A shock that's strong enough to cause a magnetic polar reversal will trigger a geologic shift of the earth's crust."

"Are you saying that a polar shift, once begun, is irreversible?"

"That's the way it looks."

"Is there any margin for error in the simulation?"

"It's so slim as to be negligible."

Austin felt as if a wall had fallen on him. "We're talking about a catastrophe."

"Worse," Trout said. "This is a doomsday scenario. The worldwide destruction if this thing is unleashed is beyond anything that can be imagined or previously experienced."

"How long do we have?"

"The reaction would be immediate. The timing depends on when the people who've been causing the whirlpools and giant waves decide to pull the switch."

"I may be able to offer a ray of hope." He told Trout about his encounter with Barrett, and the possibility of an antidote for a polar shift.

"Encouraging. When will you get back to Washington?"

"We'll make landfall tomorrow. We've got a plane waiting. I'll call when we're in the air to give you an ETA."

"I'll be standing by."

After hanging up, Austin sat in his darkened stateroom listening to the grumble of the ship's engines and cursing the slowness of ocean travel. He had been unaware of the urgency of the situation when Captain Ivanov invited him to sail on the icebreaker. Austin could have gone back with Petrov, but he politely refused the offer, saying it was important for him to talk to Karla Janos. Petrov had given him a knowing smile, and told Austin to call on him anytime.

Since coming aboard Austin had spent very little time with Karla. After she and Maria had a tearful reunion, and Uncle Karl got patched up, everyone retired to their respected staterooms to catch up on badly needed sleep.

Austin got dressed and went out on the deck, which was bathed in the subdued arctic light. The Kotelny was plowing through the ocean at a steady clip. The cold air hit his lungs like the blast from an open refrigerator. Fully awake now, he made his way to the mess hall and poured himself a mug of coffee. The place was deserted except for a couple of crewmen who were coming onto a shift. He found a corner table, slipped the phone from his pocket and called the number Barrett had given him. After a few seconds, a woman answered and said hello.

"I'd like to speak to Barrett," Austin said.

"This is Barrett. I programmed a woman's voice to take the place of mine."

"Aren't you taking this electronic cloak-and-dagger stuff a bit too far?"

"Hell, Kurt, you're not the one who got shot," Barrett said. "You don't know the kind of people you're dealing with."

"That's why I called. Do you think Gant and Margrave are open to reason?"

"Gant is about as reasonable as a rattlesnake. Tris could be reached, maybe, but he's so damned convinced of his righteous cause he doesn't care who he hurts. Why do you ask?"

Austin conveyed the gist of his conversation with Trout.

When Barrett's voice came back on, it had assumed its masculine mode. "I was afraid of something like this. Ohmigod. I'm responsible for the end of the world. I'm going to kill myself."

"If the world ends you won't have to," Austin said.

Barrett calmed down. "That's the most twisted logic I've ever heard."

"Thanks. Back to my original question. Do you think Gant or Margrave would react with the same alarm if I laid out the facts for them?"

"The difference is that I believe you. They'll think you're trying to throw a monkey wrench in their plans."

"It might be worth taking the chance. How do I get to them?"

"Gant's foundation has an office in Washington."

"I was thinking of something more casual."

"Let me think. I saw something in the paper. Gant is having some sort of private, charitable horsey thing on his estate. Maybe you can get into that. I may be able to help."

"That's a start. What about Margrave?"

"He rarely comes off of his island in Maine. He's developed a citadel mentality. He's got security people guarding the place, but I might have some ideas on how to get to him."

"It's worth a try. I'm going to do all I can to try to stop this before it gets to the trigger point. Are you still on the move?"

"Still living out of my sleeping bag. Call me when you get home."

Austin hung up, finished his coffee and was about to return to his cabin when Karla came into the mess hall. She seemed as surprised to see him as he was to see her. He beckoned her to his table.

She sat down and said, "I couldn't sleep."

"I can understand that. You've been through a lot in the last few days."

"Uncle Karl said that the men who murdered the expedition were after me. Something about a secret I supposedly know. I don't know what's going on, but I feel responsible for much of what has happened."

"It's not your fault. They think the secret was passed down from your grandfather, an electrical engineer named Lazlo Kovacs."

"You're mistaken. My grandfather's name was Janos, like mine."

Austin shook his head. "That was the name Kovacs assumed after he escaped from Germany at the end of World War Two."

"I don't understand."

"Your grandfather was being forced to work for the Nazis on electromagnetic weapons. He escaped from a secret lab shortly before the Russians overran East Prussia. He was apparently helped by a young member of the German resistance. The German's name was Karl."

"Uncle Karl! I always wondered what his connection was to my grandfather. They seemed so different yet so bound together."

"Now you know."

"This is insane! My grandfather never gave me any secret formula for a death ray or whatever it is they're looking for."

"You may know more than you know. Your paper on the extinction of the woolly mammoth hinted at deeper knowledge of his work."

"After the discovery of those creatures on the island, my paper is a joke. I can't wait to get back there to do some research."

"Petrov has vowed to work through academic rather than governmental circles to protect your furry friends. He's had some political trouble, and he thinks this will help his cause."

"I'm glad to hear that. But getting back to my grandfather, I went to him when I was in college with my theory of a cataclysmic extinction because he was the only scientist I knew. There was skepticism about a polar shift being possible. He said that it could happen, and had happened. That it could be caused by natural phenomena, or man-made, in the future, when the technology became available. He showed me some equations having to do with electromagnetism that he said proved his point. That's all. Later, when I was working on my thesis after his death, I incorporated his work into the paper."
