Petrov was carrying a bottle of vodka and three shot glasses, which he placed on the table. He came over and threw his arms around Austin, and then crushed Zavala in a bone-crunching bear hug. “I see you have met Dimitri and Veronika. They are two of my most trusted agents.”

“Joe and I never expected such a warm welcome in a cold place like Siberia,” Austin said.

Petrov thanked his agents and dismissed them. He pulled up a chair and told the others to do the same. He unscrewed the cap from the bottle of vodka, poured the glasses full and passed them around.

Raising his glass high, he said, “Here's to old enemies.”

They clinked glasses and downed their drinks. The vodka tasted like liquid fire, but it had more wake-up power than pure caffeine. When Petrov went to pour another round, Austin put his hand over the glass. “This will have to wait. We have got some serious matters to deal with.”

“I'm pleased you said we. I felt excluded after our call.” He poured himself another shot. “Please explain why you found it necessary to hop onto a plane and fly halfway across the world to this lovely garden spot.”

“It's a long story,” Austin said with a weariness that wasn't all due to the hours on a plane. “It begins and it ends with a brilliant Hungarian scientist named Kovacs.”

He laid the story out chronologically, going back to Kovacs's escape from Prussia, bringing it to the recent past, with the giant waves and whirlpool and his talk with Barrett.

Petrov listened in silence, and, when Austin was done, he pushed away his untouched glass of vodka.

“This is a fantastic story. Do you truly believe that these people have the capacity to create this polar reversal?”

“You know everything we know. What do you think?”

Petrov pondered the question for a moment. “Did you ever hear of the Russian 'woodpecker' project? It was an effort to control weather for military purposes, using electromagnetic radiation. Your country followed the same line of research for similar purposes.”

“How successful were these projects?”

“Over a period of time, there was a series of unusual weather events in both countries. They ranged from high winds and torrential rains to drought. Even earthquakes. I'm told the research ended with the Cold War.”

“Interesting. That would fit in with what we know.”

A slight smile cracked the ends of Zavala's lips. “Are we sure it ended?”

“What do you mean?”

“Have you looked out the window lately?”

Petrov glanced around the windowless room before he realized that Zavala was speaking metaphorically. He chuckled, and said, “I have a tendency to take statements literally. It's a Russian thing. I'm well aware that there the world has experienced a number of weather extremes.”
