Tidal Rip

deflected up and cut deep into the top of his shoulder bone. Felix felt an icy agony there, and the agony gave him power. Instantly he drove his knife deep into the German’s belly. He lifted and dug and twisted with the knife in his right hand. With his left arm, already covered with blood from his wound, he parried clumsily as the German’s right arm flailed around.

Felix shoved the German backward and thudded squarely on top of him, Draeger rig and all; he almost screamed from the pain of his broken ribs. His face was inches from the German’s. He could smell the man’s breath, feel the warmth of his body. The kampfschwimmer opened his mouth, silently, and Felix could see down his throat. Still he dug his knife inside the German, seeking his liver and the major blood vessels below his heart.

Blood exploded from the German’s mouth. Felix was almost blinded, but the German was definitely dead. By the time he thought to look the man in the eyes, the corneas were glazed and cloudy.

Felix quickly washed the blood from his face at the edge of the river. His left arm was nearly useless. He saw no arterial spurting, so dressing the wound would have to wait.

One-handed, he undid the hasps that sealed the shock-hardened, pressure-proof casing of the atom bomb. He lifted the lid. Felix, like all SEALs since the war began, had received basic training in atomic-weapon-arming techniques, but he was no expert. He saw the physics package, the hollow sphere of fissile metal surrounded by implosion lenses. He saw a battery power supply, arming circuitry, and the readout of a timer. The blurry numbers on the timer said the bomb had less than five minutes to blow.

Felix registered now that he’d been suffering from a splitting headache, and his eyes had trouble focusing. I’ve got a concussion. I got it in the falls.

It seemed as if hundreds of thin wires ran from the arming circuitry to tiny components embedded in the implosion lenses.

Felix had no idea if the thing was booby-trapped. He doubted he had the time or strength to pull all the wires away from the high-explosive lenses — some were under the physics package where he couldn’t reach. His addled brain did know that if even a few wires were intact when the detonation signal came, the bomb would fizzle, but it still might have a small yield, or could explode just strongly enough to send ten pounds of carcinogenic plutonium dust right into the river, upstream of Puerto Iguazu and many other cities and towns.

Felix did the only thing he could. With both hands he grabbed thick cables that ran from the power supply. He pulled with all his might; in his battered rib cage every breath was torture. The cables wouldn’t budge.

Felix felt in the mud and blood for where he’d dropped his dive knife. It was meant for emergency cutting like this. He sawed away at the cables as the bomb’s timer ran down. With only seconds to go, he cut through two cables at once — sparks flew from the positive terminal and a painful electric shock ran up his arm. The digital timer went blank. Felix waited for what seemed like forever.

Nothing happened.

Again he glanced at the sky. The Predator was still up there, watching him. Felix realized that he’d become disoriented before. Looking at the river, he saw that it ran from his right to his left. Felix was on the Argentine side.

Cursing, he closed and locked the casing of the disabled bomb. He grabbed it and instinctively reached for the body of the dead German, put his Draeger regulator in his mouth, and wearily went back into the water.

He was barely in time. Enemy troops, whether German or Argentine, began to fire into the river after him.

Felix worked his way along the bottom of the chocolate-colored torrential Iguazu once more, zigzagging at an angle to the current. As before, he used the weight of the bomb as a safety anchor in the darkness. Unlike before, he was burdened by the German corpse, and his shoulder was badly cut. The corpse — his trophy and a possible intelligence prize — kept wanting to rise to the surface. This would give his location away and draw an Argentine mortar round or grenade.

Ghoulishly, Felix elbowed the corpse’s solar plexus — below the sternum and flak vest and above the gaping wound in the guts. In a motion that aped CPR, he forced the German’s lungs to draw in water. This made the body heavy, so it sank.

But between his own unbandaged wound and gore from the dead kampfschwimmer, Felix knew he was in yet another race against time, an extremely personal one: piranhas frequented this part of the river. Though they were normally benign, a whiff of blood would draw them in hordes and trigger a feeding frenzy.

Felix struggled toward the far bank underwater as fast as he could, working blindly and in terrible pain, expecting at any moment that his strenuous efforts would cause a broken rib to puncture a lung. Before he got much farther he heard repetitive pounding through the water and he felt it through the upslope of the riverbank. Brazilians with heavy machine guns had converged on the scene. They were holding off the Argentines. Felix saw the water change color, streaks of livid green. He realized the Brazilians were releasing piranha repellent into the river.

Felix clambered up the bank to the welcoming arms of Brazilian soldiers. They grabbed the bomb and the German’s body while heavy machine guns continued to rake the far bank with crisscrossing red tracer fire.

Felix ran out of absolutely everything and collapsed.

Brazilian medics stripped off his gear and loaded him onto a stretcher, then carried him behind good cover. They started to bandage his wounds and inserted an intravenous plasma drip; they checked his pupils’ reflexes with a flashlight and seemed satisfied. Away from the machine guns, Felix could hear the noise of friendly helicopters. The enemy drone was gone.

He tried to talk but a medic told him to be quiet. The medic congratulated him for his man-to-man victory against the German. Felix desperately wanted to ask about his men, his team. He tried to rise from the stretcher, but grimaced as his torso muscles flexed against his ribs. Someone pushed him gently back. He felt a different jab in his arm. Felix drifted away on the irresistible bliss of a morphine shot.

CHAPTER 36

Beneath the helo, on the surface of the sea, Jeffrey saw a Brazilian Navy hovercraft. But instead of going at over forty knots in a plume of spray, it was barely moving and black smoke issued from the diesel exhaust. He knew the engine trouble was fake.

The helo approached the hovercraft, and dropped off Jeffrey and a Brazilian Navy specialist. Then the diving gear and spare parts were handed down.

Jeffrey went into the soundproof wheelhouse of the hovercraft. The repair specialist who’d come with him had been picked for the job because he spoke passable English and had a high security clearance.

The navy chief in charge of the hovercraft was very excited to see them. Jeffrey remembered the ticking atom bomb.

But the chief seemed happy, delighted even, not angry or scared. He and the specialist spoke in Portuguese, the latter translating for Jeffrey as best he could. Over the radio, they’d learned that Felix Estabo had disarmed the stolen bomb, and retrieved it. He was wounded but safe, in a good Brazilian hospital.

Jeffrey was very proud of Felix. As the news sank in, he felt elation and almost giddy relief, but he forced himself to refocus. He knew he still had some very big problems.

Jeffrey and the repair specialist donned their scuba gear. Together they entered the water and dove under the hovercraft, supposedly to fix a broken part.

Jeffrey swam deeper. There beneath him was Challenger’s sail. A pair of divers waited, in scuba gear like his own. Since they were right under the hovercraft, the extra bubbles the four men’s rigs gave off wouldn’t show on the surface.

Jeffrey traded places with someone from Challenger. He was an enlisted man, one of the ship’s qualified safety divers, selected by COB because his height and build were similar to the captain’s. Jeffrey was sure he’d be crestfallen to be left behind when the ship was going into combat, but security needed to be maintained: two men in broad daylight had dived under the conspicuous hovercraft, so two men had to come up. To cheer the departing crewman, Jeffrey patted him on the shoulder and shook his hand underwater. He gave the young enlisted man an encouraging thumbs-up; if all went well, they’d be reunited in New London soon enough.
