"You know why I am here?"

The man nodded.

"As you hope to see Allah, you will tell me what you know."

The armored column of the 10th Armored Cavalry Regiment ran from the Negev to the border of Lebanon. Overhead was a full squadron of F-16s, and another of Tomcats from the USS Theodore Roosevelt. The Syrian army was also deployed in force, though its air force was staying out of the way. The Middle East had taken its lesson on American air power. The display of force was massive and unequivocal. The word was out: nobody would get in the way. The vehicles drove deep into the small, abused country, and finally onto a valley road. The spot had been marked on the map by a dying man anxious to save what remained of his soul, and only an hour's work was needed to determine the exact location. Army engineers found the entrance and checked for booby-traps, then waved the others in.

"God Almighty," Dr Lowell said, swinging a powerful light around the darkened room. More engineers swept the room, checking for wires on the machines, and carefully checking every drawer of every table before the rest were allowed farther than the door. Then Lowell went to work. There was a set of plans that he took outside to read in the light.

"You know," he said after fifteen minutes of total silence, "I never really appreciated how easy this was. We've had this illusion that you really needed to -" He stopped. "Illusion, that's the right word."

"What are you telling me?"

"It was supposed to be a five-hundred-kiloton device."

"If it had gone off right, we would have known it had to be the Russians," Jack said. "No one could have stopped it. We wouldn't be here now."

"Yeah, I think we have to adjust our threat estimate some."

"Doc, we think we found something," an Army officer said. Dr Lowell went inside, then returned to don protective clothing.

"So large as that?" Golovko asked, staring at the plans.

"Clever people. Do you know how hard it was for me to persuade the President that - excuse me. I didn't, did I? If this had been a big one, I would have believed the report."

"And what report is that?" Golovko asked.

"Can we conduct a little business?"

"If you wish."

"You're holding someone we want," Jack said.

"Lyalin?"

"Yes."

"He betrayed his country. He will suffer for it."

"Sergey, first, he gave us nothing that we could use against you. That was his deal. We only got the take from THISTLE, his Japanese network. Second, except for him and what he gave us, we might not be here now. Turn him loose."

"In return for what?"

"We have an agent who told us that Narmonov was being blackmailed by your military, and that your military was using some missing tactical nuclear weapons to make it stick. That's why we suspected that the weapon might have been yours."
