ON THE WAY back to NUMA headquarters, Sandecker punched out a number on his cell phone. “Rudi, please meet me in my office in ten minutes.” Sandecker drove into the garage under the thirty-story tubular building that served as the nerve center for NUMA's worldwide operations and took the elevator to his top-floor office. He was behind the immense desk made from the hatch cover of a Confederate blockade runner when Rudi Gunn arrived carrying a briefcase.

Sandecker waved his second-in-command to a chair. Gunn, a short thin man with narrow shoulders, thinning hair and thick horn-rimmed glasses, listened intently while Sandecker described his White House meeting.

“Then we're pulling out of the search?” Gunn said.

Sandecker's eyes blazed. “Hell, no! The fact that they put a shot across my bow doesn't mean I'm going to heave to and run up the white flag. What have you learned?”

“I went right to work on the premise we had discussed. That the only thing with the ability to hijack the NR-1 from under the nose of its support ship would be a bigger sub. Any number of countries have submarines large enough to carry off the NR-1,” Gunn said. “I asked Yaeger to run some profiles.” Hiram Yaeger was NUMA's computer whiz and head of its vast data network. “We concentrated on the USSR because of their preference for building monster boats. My first thought was something like the Typhoon.”

Sandecker sat back in his chair and cradled his chin in one hand. “With a length of more than five hundred feet, a Typhoon could easily piggyback our missing minisub.”

“I agree. They were designed to fire missiles from the Arctic Circle. The flat missile deck could have been converted for carrying cargo. But there was a problem when I checked further. All six Typhoons were accounted for.”

“All right. But I've never known you to give up easily, Rudi. What else do you have?”

Gunn reached into his briefcase and pulled out a folder. He handed a picture from the folder to Sandecker.

“This shows a Soviet India-class sub photographed on its way to the Pacific from the Northern Fleet.” He passed over several sheets of paper. “These are schematic diagrams. She's a diesel-electric, nearly three hundred fifty feet long, and was designed supposedly for underwater rescue. That semirecessed area abaft the sail was fitted out to carry a couple of deep-diving minisubs. In wartime they could be used for clandestine ops with Spetsnaz special forces brigades. Only two India-class subs were built. They were to have been broken up after the end of the Cold War. We've been able to verify that one was indeed scrapped. We don't know the fate of the other. I think it was used to hijack the NR-1.”

“You sound quite sure of this, Rudi. Remember, our premise is still only a theory.”

Gunn smiled. “May I borrow your VCR?”

“Be my guest.”
