vulnerable she was, completely out in the open with no darkness or tunnel to hide her. Any second the killers would crest the dunes, and she'd be an easy target for their bullets.
The kneedeep water covering the salt flats seemed to go on forever, slowing her progress but offering no protection. She pressed on, leaping with long strides, and eventually the water got to waist level. She dove under just as angry lead bees filled the air. The water behind her erupted in a patch of angry foam. Nina dove under and swam off at an angle for as long as she could, surfaced for air, and dove again, porpoisestyle. Once beyond the brownish water over the flats and into the deeper blue ocean, she glanced back and saw maybe a dozen figures on shore. Some had waded into the shallows. The gunfire seemed to have stopped.
Pivoting, Nina fixed her eye on the ship, concerned that it would weigh anchor and leave her between the devil and the deep blue sea. A swim to the Canary Islands wasn't in her plans. Rolling onto her back, she looked up at the puffy gilt-edged clouds and caught her breath. At least it was a good day for a swim. She rested only a minute. She had to get the blood moving in her body again.
Pace yourself, rest when necessary, and count your blessings. Calm sea and no wind or currents. No different from the swim phase of a triathlon, except for one thing: if she lost this race, she would die. Taking a bead on the ship's main mast, she threw one arm in front of the other.
Without her wristwatch, there was no telling how long she swam. The water grew colder the deeper it got, and she counted strokes to take her mind off the energy-sapping chill. Waving at the ship would be a waste of time. Her arm would look like tire neck of a floating seabird.
She tried singing sea chanteys. The old shipboard work songs helped keep the rhythm of strokes.
Her repertoire was slim, and after she'd sung 'Blow the Man Down' for the fiftieth time she simply chopped away at the sea. She drew closer to the ship, but her strokes were becoming sloppy, and she stopped to rest more often. At one point she spun around and was pleased to see she was leaving the low brown shore far behind her. To give herself courage she imagined climbing aboard the ship and washing away the salty dryness of her mouth with a steaming mug of hot coffee.
The deep thrumming sound was so faint she didn't notice it at first. Even when she stopped to listen Nina thought it might be water pressure in her head, or maybe even the noise of a ship generator. She rolled one ear in the water and listened.
The droning was louder.
Nina slowly wheeled around. A dark object was racing in her direction from shore. She thought it was a boat at first, but as it grew quickly in size Nina made out a squat ugly black hull she recognized as that of a large hovercraft, an amphibious vehicle that moves across land and sea on a cushion of air.
It moved back and forth in a series of sharpangled turns, but Nina sensed this was no rescue boat executing a search pattern. Its course was too determined, too aggressive. All at once it stopped zigzagging and came straight at her like a bullet. She must have been spotted. Rapidly it closed the distance and was practically on top of her when she dove as deep as she could go.
The hovercraft skimmed overhead on its teninch cushion, churning the water into a wild frenzy. When she could stay under no longer, Nina surfaced and sucked in air, only to cough as the purple exhaust fumes filled her lungs. The hovercraft spun around and made another pass.
Again she dove. Again she was tossed and buffeted only to fight her way back to the surface, where she bobbed in the wake.
The hovercraft stopped, settling down into the water with its engines purring, facing Nina like a big cat toying with a mouse. A weary and waterlogged mouse. Then the engines came to life, the hovercraft rose up on invisible legs and charged again.
Nina dove and was tumbled like a rock in a polishing machine. Her brain was numb; blood thundered in her ears. She was reacting on pure instinct. The game would end soon. The damned thing could turn on a dime. Each time she surfaced she had less time to take in air, and the craft was closer than before.
The blunt hull was coming at her again, although she could hardly see it with the exhaust cloud and her eyes bleary and stinging from salt water. She was too exhausted to dive and wouldn't have the strength to fight her way up from the sea again. She made a pitiful attempt to swim out of the way, but after a few strokes she turned to face her attacker as if she could beat it back with her fists.
The hovercraft was nearly on top of her, its flatulent roar filling her ears. She clenched her jaw and waited.
The horror of the past several hours was nothing compared to what happened next. The hovercraft was only seconds away when her ankles were clutched in a viselike grip and she was dragged down into the cold depths of the sea.
6 ARMS FLAILING LIKE A WINDMILL IN a gale, Nina struggled to break free, but the iron lock on her ankles never let up even as the maelstrom created by the hovercraft whipped the water around her to a wild frenzy. She emptied her lungs in one last defiant gesture, an angry, frustrated scream that came out as a muted explosion of bubbles.
The grip on her legs relaxed, and a vaguely human form began to take shape in the turbulent cloud of bubbles kicked up by the hovercraft. Like some alien cyclops from a UFO the amorphous shape came closer and solidified until the plexiglass of a diver's mask was only inches from her face. Peering from behind the lens were piercing light blue eyes that projected strength and reassurance rather than menace.
A gloved hand came up, wagged a regulator back and forth in front of her nose, and pressed the purge button so the belching mouthpiece would get her attention. Nina grabbed the regulator and hungrily bit down. No flowerscented breath of summer was ever sweeter than the lifegiving compressed air that flowed into her lungs. The leveled hand was moving up and down.
Take it easy. Slow down.
Nina nodded to show she understood the diver's signal and felt a gentle squeeze on her shoulder. She continued to breathe off the 'octopus' backup emergency hose until eventually her panic passed and her breathing became more rhythmical.
Another hand signal. The forefinger and thumb formed into a vague O.
Okay?
Nina imitated the gesture.
I'm Okay.
Behind the mask a blue eye winked. She didn't know who this aquaman was or where he came from, but at least he was friendly. The diver's head was covered by his closefitting hood and a combined helmetmask arrangement. She could see only that he was a big man with wide shoulders.
Nina looked up. The light was shredded in the wake of the hovercraft's violent passage, and engines rumbled through the water. They were still looking for her.
Pressure on her shoulder again. Aquaman pointed toward the surface and clenched his hand in a fist.
Danger.
She nodded vigorously. The thumb pointed downward. She looked below her dangling legs into the gloomy depths. Even the unknown was preferable to the real dangers that lurked above. She nodded again and gave the okay signal. He clasped one hand in the other.
Hold hands.
Nina took his proffered glove, and slowly they began to descend.
The water changed from cobalt to indigo as they continued their measured plunge, becoming so dark that Nina felt the cold bottom muck before she saw it.
From his belt the diver produced a small but powerful high-intensity Tektite strobelight and held it above his head. She dosed her eyes so as not to be blinded by the intense silvery-white flash she knew was coming. When she looked again an undersea firefly was blinking in the distance.
The diver put his forefingers together.
Swim side by side in that direction.
Again holding hands, they swam toward the pulsating light until they neared a second diver. He saw the swimmers coming his way, switched off the strobe he was holding, and his hand went to the microphone button of his Aquacom headset.
'I can't take you anywhere,' he said. 'I let you out of my sight for a minute, and you show up with a real live mermaid.'
