Clive Cussler - Serpent

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."

The first diver let his eyes travel over Nina's body and decided the description wasn't far off the mark. With her golden tresses, long legs, and minimal covering, Nina easily could have passed for a mythical sea sprite, except for one thing.

"Mermaids are half fish," he said.

"I like the new improved model better. What's her name?"

"Good question. We haven't been formally introduced yet. I bumped into her when I went up top to check on the ship. She was in a bit of trouble, so I gave her a hand. Two hands, actually"

Nina had never used underwater communicators herself, but she recognized the equipment and knew they must be talking about her. As grateful as she was, she wished they would cut their conversation short. She was freezing If she didn't move soon, she'd pass out. She crossed her arms in front of her chest.

I am cold.

The diver she had dubbed Aquaman nodded. With the protection of his drysuit, he had forgotten how cool it must be for an unprotected body.

"Let's get our mermaid back to the ship before she turns into a frozen fish stick."

The other diver checked his compass and led the way. Nina's new friend signaled her once more to swim side by side and gently took her hand. She assumed they were heading for the ship, but in her cold and exhausted condition she wasn't sure she could make it. The diver seemed to sense her struggle to follow with no fins on her feet and squeezed her hand several times in encouragement.

They swam for only a few minutes before they glided down again. A pair of yellow objects sat on the bottom. They were made of plastic and shaped like fat miniature torpedoes with ears. Nina recognized them as DPVs, diver propulsion units, or sea scooters as they were more commonly called.

The divers each picked up a DPV and squeezed the throttles. There were low whines as the battery-driven twin motors in the Stingrays kicked their twin propellers into action. Aquaman pointed to his back. Nina grabbed onto his shoulders, and they ascended to midwater where it was marginally warmer.

As they glided along Nina's diver called the ship and asked if anyone could see a big hovercraft in the vicinity. He wasn't one to take chances.

"There was a hovercraft around earlier," the message came back. "It headed for land and seems to have disappeared."

"Roger. Please be prepared for a female visitor."

There was a slight pause. "Say again?"

"Never mind. Just be prepared to treat hypothermia."

They surfaced near the ship and swam around to the stern. A welcome party awaited to help Nina aboard and wrap her in towels and blankets. Nina's face was mottled, and her lips were blue. She refused the stretcher but was glad for a helping hand as she walked with wobbly legs, teeth chattering, to the infirmary. She limped on the foot she'd injured escaping the assassins.
