Eddie had been alone on the sub since launching off the Oregon fifteen days earlier. With the harbor ringed with underwater listening stations and routinely swept with active sonar, it had taken that long for Seng to drift into the heavily defended port. He had grounded the sub during the slight ebb tide and allowed her to drift when the tidal surge washed into the harbor, only chancing to run the electric motors under the cover of an inbound ship or patrol boat. There was no other way to get the sub into the naval base without being detected.
While there were other sub drivers among the Oregon crew, as director of Shore Operations, Eddie wouldn’t let anyone else take the risk. Seng was another veteran of the CIA, although Juan hadn’t known him when they were in the Agency. He’d spent most of his career working the Middle East, while Eddie had been attached to the American embassy in Beijing running several successful spy networks. Budget and policy shifts following 9/11 had seen him transferred to a stateside desk. Still hungry for what he called “the teeth of the trade,” Seng had joined the Corporation and quickly established himself as an indispensable member.
Cabrillo crawled over batteries and empty crates and slid into the copilot’s seat to Eddie’s right. Eddie’s black hair was lank from going so long without washing, and stubble marred his otherwise sharp features. The emotional and physical strain of the past two weeks had dimmed his normally bright eyes.
“Hiya, boss.” Seng grinned. Nothing could diminish his easygoing charm. “Welcome aboard.”
“Thanks,” Juan said, noting that the sub had already descended to thirty feet. “The clock’s ticking, so set a course out of the harbor and punch it. We’ve got eleven minutes.”
The Discovery’s motors ramped up, and the single prop bit into the water. There was nothing they could do about the noise. They had to get as far from the Asia Star as possible, because water does not compress, making the coming shock wave doubly brutal.
Cabrillo kept his eyes on the sub’s sonar, and only a minute after they began pulling away from the doomed freighter there was contact. “Mr. Murphy’s rearing his ugly head.”
“What do you have?” Hanley stood just behind Juan and leaned over his shoulder.
The computer analyzed the acoustical signal, and Cabrillo read the grim facts. “Sinpo-class patrol boat. Crew of twelve. Armed with a pair of 37mm autocannons and tilt racks for depth charges. Top speed is forty knots, and our contact is already churning twenty and headed straight for us.”
Eddie turned to Juan. “It’s routine. They’ve been doing this ever since I entered the harbor. Every couple of hours a single patrol boat races along the dock. I think they’re searching for sailors trying to jump ship.”
“If he maintains his course, he’s going to pass right over us.”
“Does that class of boats carry sonar?” Max asked.
Juan checked the computer again. “Doesn’t say.”
“What do you want me to do?” Eddie’s voice remained calm and professional. “Keep running, or settle onto the bottom and let him pass?”
Cabrillo checked his watch again. They’d traveled little more than a quarter mile. Too close. “Keep going. If he hears us or detects our wake, he’s going to have to slow and turn back to try to find us again. We only need six minutes.”
A moment later the four men inside the minisub could hear the thrash of the patrol boat’s props through the water, an angry sound that rose in pitch as the craft drew closer. As it roared overhead the din filled the hull, and the men waited expectantly to hear if it would come back for another pass. The moment stretched as time turned elastic. Max and Hali let out their breaths as the patrol boat continued on. Cabrillo kept his eyes glued to the sonar screen.
“They’re turning,” he remarked a second later. “Coming back for another look. Hali, check the radio, see if he’s transmitting.” Hali Kasim headed the Oregon’s communications division and could play radios like a concert pianist.
The communications suite aboard the Oregon was sophisticated enough to scan and record a thousand frequencies per second and had a language program that could translate fast enough for an operator to hold a conversation close enough to real time to fool most listeners. With the Discovery 1000’s limited electronics they would be lucky just to pick up a broadcast, and since none of the men spoke Korean, they wouldn’t know if the patrol craft was asking permission to depth charge or commenting on the weather.
“I’m not getting anything,” Kasim answered after a few moments.
The North Korean patrol boat crossed over the minisub again, and the men heard her engines throttle back.
“They’re pacing us,” Eddie said.
The powerful sonar picked up a pair of splashes too small to be depth charges. Juan knew immediately what was about to happen. “Brace yourselves!”
The grenades were knockoffs of the Soviet RGD-5, and while they only contained four ounces of high explosives, the water amplified their explosive power. The two grenades went off nearly simultaneously just yards behind the Discovery. The sub pitched up by the stern, knocking Hali Kasim against a bank of batteries. Eddie fought to bring her nose up as the murky bottom suddenly loomed outside the large acrylic view port. With their ears ringing, no one heard a second pair of grenades hit the water. They blew just above the minisub, slamming her into the mud just as Eddie got her on an even keel. Billows of silt exploded around the Discovery, cutting visibility to zero. Electricity arced and snapped from a loose connection in dazzlingly bright flashes that temporarily blinded the men.
Eddie quickly powered down the sub to give Max a chance to fix the connection. By the glow of a miniature flashlight clamped between his teeth, the engineer worked to bypass the affected row of batteries, but the damage had been done. The flashes of electricity could be seen from the surface through the sub’s portholes and looked like an eerie blue glow from the depths.
“They’ve got us now,” Hali said. “They’re transmitting something. Just a short message, but I think the jig is up.”
“How’s it coming, Max?” Cabrillo inquired with no more concern than if he were asking when coffee would be ready.
“Just a few more seconds.”
“Anything from shore yet, Hali?”
“Negative. The brass must be mulling over the report from the patrol boat.”
“Got it,” Max announced. “Eddie, turn her back on.”
