“As you know, Dr. Heiland’s company was engaged in a high-level research-and-development project for DARPA. His work was in support of a secret Navy submarine program called Sea Arrow. Heiland was specifically involved in the development of an advanced propulsion system. I really can’t tell you more than that except that he was doing some final prototype testing on a breakthrough development when his boat was lost at sea.”

“That was the item in the crate?”

“A scale model,” Ann said. “While there was a suspicion of foul play in the loss of the Cuttlefish, no one anticipated any interference with our search-and-recovery project. I’m truly sorry your crew was placed in danger. It was thought that the fewer people aware of Heiland’s research, the better. I know the Vice President wasn’t happy about keeping you in the dark, but he was forced to go along at the request of Tom Cerny.”

“So who were those guys who tried to steal it?” Gunn asked.

Ann shrugged. “A mystery, at the moment. By their looks, I don’t believe the men were from Mexico, but possibly Central or South America. I’ve already spoken to Washington and been assured we’ll have the Mexican authorities’ assistance in examining the two bodies and tracing the pickup truck.”

“We’ve provided a pretty good description of their boat to the Mexican Navy,” Gunn said.

“They don’t seem like the usual suspects for a defense-related theft,” Pitt noted. “Did you think they had already absconded with Heiland’s magic box?”

“Yes,” Ann said. “When the bodies of Heiland and his assistant were found, we presumed they had been hijacked at sea and the prototype stolen. That’s why I was so shocked to see the crate still secured aboard the Cuttlefish.”

“I guess you have Heiland to thank for that,” Pitt said. He described his discovery of the orange wires and hidden toggle switch. “I’m guessing that Heiland realized he was under attack and blew up his own boat.”

“The two bodies showed severe trauma consistent with a fire or explosion,” Ann said. “We never considered it was of their own doing, but that may need to be reevaluated now.”

“I think Heiland beat them to the punch,” Pitt said. “And, to make matters worse for the bad guys, the Cuttlefish sank in water too deep for conventional diving. They were probably scrambling to locate their own salvage ship when we showed up. So they let us raise it for them.”

Gunn turned to Ann. “Your high diving saved the day.”

“No, it was Dirk and Al who recaptured the crate. Though its destruction saved it from falling into the wrong hands, the loss of the model has magnified some other problems.”

“Namely?” Pitt asked.
