The immediate problem was Tongju and his Glock 22. Any resistance would be futile while the assassin kept his gun aimed at them, as there was little doubt he would use it without hesitation. Tongju followed the four guards as they herded Dirk and Summer to the elevator, his pistol still drawn. As the doors slid open, two pairs of hands shoved them forcefully to the rear of the elevator. Tongju barked something in Korean, and then, to Dirk's relief, remained standing in the dining hall with one of the guards, a menacing look of satisfaction on his face as the elevator doors slid shut.

The elevator was cramped with five bodies in it, which would work to their advantage. Dirk glanced at Summer and nodded ever so slightly, his sister acknowledging the silent message with a quick wink. She immediately grabbed her stomach and groaned, leaning forward as if she were about to vomit. The nearest guard, a chunky man with a shaved head, took the bait and bent down slightly toward Summer. Like a cat mistakenly pouncing onto a hot stove, she suddenly sprang her body upright, jerking her knee into the man's groin with all the might she could muster. The man's eyes nearly burst out of their sockets as her knee hit home and he doubled over in agony, a shriek of pain quivering from his lips.

Summer's move was all Dirk needed to neutralize guard number two. As all three guards' attention turned initially to Summer, he launched an uppercut that connected squarely on the man's jaw, nearly lifting him out of his shoes. Dirk watched from inches away as the man's eyes rolled to the back of his head and he slumped to the floor unconscious.

Guard number three took a small step back as the fighting broke out and attempted to raise the muzzle of his rifle at Dirk. Summer reacted by grabbing the shoulders of the man she'd kneed and shoving his hunched-over body toward the standing guard. The still-groaning bald man swayed heavily into his taller accomplice with just enough force to offset the other man's balance. It was enough time to allow Dirk to step over the fallen guard and let go a left cross that landed a glancing blow on the gunman's temple. The dazed guard tried to counter with a braced karate kick, but Dirk's right fist was already there, mashing solidly into the man's larynx. The guard's face turned blue as he fought to take in air and he dropped to his knees, grabbing his throat with both hands. Dirk grabbed the man's assault rifle and swung it around viciously, striking the stock against the face of the guard struggling with Summer. The blow threw the man against the back of the elevator, where he slid to the floor unconscious.

“Nice work, Smokin' Joe,” Summer praised.

“Let's not wait for round two,” Dirk gasped as the elevator descent slowed beneath their feet. He checked that the safety on the assault rifle was turned off, then prepared to leap out of the elevator as the doors opened. Only there was no where to go.

As the doors slid open, the muzzles of three AK-74s were thrust in, the compensators at the end of the gun barrels poking into their faces. A security guard sitting at a bank of television monitors had witnessed the fracas in the elevator over closed-circuit video and quickly dispatched a cadre of guards in the vicinity.

“Saw!” the guards yelled in Korean, their meaning perfectly clear. Dirk and Summer froze in their tracks, wondering what degree of hair triggers existed on the assault rifles pointed their way. Dirk gently dropped his rifle to the ground, detecting a stirring in the elevator behind him. Too late, he turned to see the third guard staggering from the elevator while swinging the butt of his rifle toward his head. He tried to duck but the gun handle was too far along its way toward the top of his skull, where it collided with a thump.

For an instant, he saw a blinding light and shining stars, and, through the fog, an odd glimpse of Summer's feet. But that soon gave way to a fading darkness that turned to black as the curtain closed and he crumpled to the ground in a limp heap.

A throbbing jolt of pain shooting down from the top of his skull to the tip of his toes was the first evidence sent to his brain that he was still alive. As consciousness slowly seeped back to Dirk, his mind performed a physical inventory, denoting via neural signals which parts of the body were deviating from their normal state. Pain signals from his wrists, arms, and shoulders began registering as if they were pulling at a great weight, but were easily outclassed by the agonizing pangs from his head. More confusing to his senses was the feeling from his feet and legs that he was standing in a bucket of water. As the shroud of fog gradually lifted, he opened his eyes to a wet, dark, and gloomy cave.

“Welcome back to the land of the living,” Summer's voice echoed through the gloomy cavern.

“You didn't happen to get the license number of the truck that hit me?” he said groggily.

“Yes, but I'm pretty sure he wasn't carrying insurance.”

“Where the hell are we?” Dirk asked, his mind beginning to register the concepts of time and space.

“A side cavern, just off Kang's floating dock. That cool water nibbling at your navel is the River Han.”

The bucket of water he thought he was standing in was in fact a cavern full of rising river water. His vision now cleared, Dirk could see through the murky light that Summer was spread-eagled and handcuffed to two large barge anchors. Large weights rather than actual anchors, they were nothing more than a three-foot-square block of concrete. The white blocks were slickened with a decade's coating of pale green algae, with a rusty iron mooring ring protruding from the top. Dirk saw that there were nearly a dozen of the weights aligned in a row across the floor of the cavern. He and Summer stood adjacent to each other, their arms stretched wide with each wrist handcuffed to adjoining blocks.

Dirk's eyes wandered about the dim cavern. In the fading dusk light that filtered through the mouth of the cave, he could see the distinct line on the wall that he was looking for. It was the high-water mark, which he noted uncomfortably ran two feet above their heads.

“Death by slow drowning,” he said.

“Our Fu Manchu friend, Tongju, was most insistent,” Summer replied grimly. “He even prevented one of the guards from shooting you so that we could wallow down here together.”

“I must remember to send him a thank-you card.” Dirk looked down and saw that the water was now sloshing around his rib cage.

“Water's rising pretty fast.”

“We're near the mouth of the Han River, so there's plenty of tidal surge at work.” Summer gazed fearfully at her brother. “I'd estimate that the water level has risen over a foot in the last hour.”

Seeing the despair in his sister's eyes, Dirk's mind engaged in high gear to determine a means of escape. “We have another hour and a half, tops,” he calculated.

“I just remembered something,” Summer said, crinkling her brow. “I've got a small nail file in my side pocket. Might be like trying to kill a pterodactyl with a flyswatter, but it might help.” “Sure, toss it over,” Dirk replied.

“This one mooring ring looks pretty mangy,” she said, tugging at her left wrist. “If I could just get one hand free.”

“Maybe I can help.” Dirk slid his legs toward Summer, leaning his torso at an angle along the concrete blocks for support. Raising one leg, he slid his foot along until the sole of his shoe met up with the face of the protruding iron. Applying as much pressure as he could, he pressed his weight hard against the top of the metal ring.

Nothing happened.

Shifting his foot so that his heel was against the ring, he pushed once more. This time, the ring bent a fraction toward Summer. Jamming his weight repeatedly against the stanchion, he gradually forced the ring to bend over nearly ninety degrees.
