Tongju returned to the pilothouse and peered out the heavy-paned windows at the rolling sea two hundred feet beneath him. The swaying of the platform was slight as the motion rolled up from the distant pontoons beneath the surface. Gazing to his right, he saw the Koguryo begin to peel away from the Odyssey, its ferrying services complete for the time being.

“Increase speed to maximum,” his said to the helmsman.

The nervous Filipino adjusted the propulsion controls on both pontoons and then watched as the digital speed indicator slowly counted upward.

“Twelve knots, sir. Maximum cruising speed,” the seaman replied, his eyes twitching back and forth.

Tongju nodded in satisfaction, then reached for an overhead radio transmitter and called Captain Lee on the Koguryo.

“We are progressing on schedule. Please notify Inchon that we are in control of the launch vessel and intend to initiate launch countdown in approximately thirty hours. Out.”

The apprehensive helmsman stared straight ahead, avoiding the gaze of Tongju. Whatever fearful thoughts tumbled around his head about Tongju's intent were minuscule compared to the commando leader's true objective.

IT took the launch vehicle engineers just under twenty-four hours to convert the rocket's payload into a weapon of mass horror. Like surgeons conducting a transplant operation, the engineering team carefully removed several sections of the outer payload fairing and delved into the inner workings of the mock satellite. Fake components, built to resemble communication transponders, were removed and replaced with small electric pumps, which would drive the aerosol system. Lines and fittings were attached to the phony solar panels, which would open in flight to spread the rejuvenated virus, disseminating it as a fine mist across the California sky.

Working in protective clean room bunny suits, the technicians performed a final test on the dispensing system, ensuring it was fully functional for the short rocket flight. The final step of the operation was then reached: inserting the chimera virus into the payload vehicle. The canisters from Inchon containing the freeze-dried germs were carefully mounted to the satellite frame and steel braided lines from the hydrogenation tanks were connected to the aerosol system. When activated, a software-controlled program would vacuum-mix the powdered substance with purified water, then transfer the live fluid through the vaporizer and out into the atmosphere.

With the deadly cocktail loaded aboard, the payload fairing was reassembled around the satellite. Propellant explosives were inserted at key points inside the fairing to blast the payload doors away at the appointed moment during flight. When the final section of the nose cone housing was sealed into place, the tired engineering team congratulated one another briefly and then staggered toward the crew's quarters. A few precious hours of sleep was all they could ask for before it would be time to start the final launch countdown.

Without publicly raising the color-coded Threat Advisory System, the Department of Homeland Security quietly issued an elevated marine port and airport security alert. Stepped-up screening and random searches were performed on all aircraft and vessels originating from an Asian locale, with special inspections for biological and chemical agents. At Vice President Sandecker's insistence, the Coast Guard was ordered to stop, board, and search all Japanese- or Korean-flagged inbound ships with a fully armed security contingent. All available Coast Guard cutters were put to sea along the West Coast, concentrated around the commercial hubs of Seattle, San Francisco, and Los Angeles.

In San Francisco, Rudi Gunn coordinated NUMA's interdiction support with the local Coast Guard commandant. When the research vessel Blue Gllartived from Monterey, Gunn immediately assigned her picket duty ten miles off the Golden Gate Bridge. He then jumped up to Seattle, where he directed local NUMA resources in support of coastal screening, and enlisted the aid of the Canadian Coast Guard in Vancouver to search all British Columbia-bound ships.

Dirk and Summer flew to San Diego, where they were welcomed by the city's trademark seventy-two-degree balmy weather. Taking a short cab ride from San Diego International Airport's Lindbergh Field to Shelter Island, it took them only a few minutes to locate the Deep Endeavor tied up at the end of a large municipal dock. As they approached the ship, Dirk noticed that an odd-shaped submersible painted a metallic burnt orange sat on the vessel's stern deck.

“Well, if it isn't the Prisoners of Zenda,” Jack Dahlgren called from the bridge wing upon spotting the twosome boarding the ship. Dirk's close friend hopped down a stairwell and met them at the head of the gangway.

“Heard you two enjoyed a seaside tour of the Korean Peninsula,” Dahlgren laughed as he shook Dirk's hand firmly, then gave Summer a hug.

“Yes, but we somehow missed the Mkhelin-mt&A attractions,” Summer grinned back.

“Now, wait, that DMZ tour was pretty stimulating,” Dirk said, feigning seriousness. Turning to Dahlgren, he asked, “You and the crew ready to do a little search-and-seizure work?”

"Yep. A Coast Guard team joined us an hour ago so we're ready to shove off at any time.

“Good. Let's get after it, then.”

Dahlgren escorted Dirk and Summer up to the bridge, where they were greeted by Leo Delgado and Captain Burch, then introduced to a uniformed Coast Guard sea marshal named Aimes.

“What's our intercept procedure, Lieutenant?” Dirk asked, noting the insignia on Aimes's uniform.

“Call me Bill,” replied Aimes. A studious man with cropped blond hair, Aimes took his duty seriously but hated unnecessary formality “We'll be assisting the regional Coast Guard vessels as a backup, when and if commercial traffic gets particularly heavy. Otherwise, we'll be assigned to ad hoc survey and reconnaissance. Under legislative rule, we can intercept and board all inbound commercial vessels up to twelve miles offshore. As NUMA's Coast Guard representative, I will lead all boardings and searches with my team but will be assisted by several of your crewmen who have undergone a brief training session.”

“What are the chances we could actually locate a weapons cache or bomb hidden on a large containership?” Summer wondered.

“Better than you might think,” Aimes replied. “As you know, we work closely with the Customs Department under the direction of the Homeland Security Department. Our customs agents are located at foreign ports around the globe and are on site to inspect and seal all cargo containers before the goods are allowed to ship. Upon arriving in U.S. ports, containers are verified by customs agents as having not been opened or tampered with before acceptance into this country. The Coast Guard provides an advance check of the ship and containers before they have a chance to reach port.”

“There's plenty of places on a ship outside of the cargo containers where somebody could hide a bomb,” Dahlgren stated.

“That's a more difficult problem, but it's where the dogs come into play,” Aimes replied, nodding his head toward the far end of the bridge. Dirk noticed for the first time that a pair of yellow Labrador retrievers were tied to a bulkhead stanchion and lay asleep on the deck. Summer had already made her way over to the dogs and begun scratching them contentedly behind the ears.

“The dogs are trained to sniff out a variety of explosive compounds commonly used in bomb manufacture. Best of all, they can run through a ship in quick order. If a biological bomb is being smuggled in on a containership, there's a good chance those boys could sniff out the explosives component of it.”

“That's what we're looking for,” Dirk said. “So, we'll be working off of San Diego?”
