Skillfully handling the thruster controls, Austin piloted the Hardsuit horizontally, tilting forward slightly, cable trailing behind.

The seven-hundred-pound ADS lost its clumsiness and moved through the water as if on wings. Austin focused on a small sonar screen glowing wheat-colored yellow. Employing a range of fifty feet to either side of the suit, it cut a swath a hundred feet wide. It tracked his position, heading, speed, and depth as it read the bottom.

A dark object appeared on the screen, approximately twenty-five feet to his right and down.

Austin maneuvered the Hardsuit into a sharp right turn and descended until the searchlights reflected off the gleaming plastic-and-metal surface of the ROV. It was lying on its back like a dead beetle.

Gannon also saw it. “Thanks for finding our ROV,” his voice came over the communicator.

“My pleasure!” replied Austin. “B3 should be within spitting distance.”

He extended the range of his search a hundred feet, then spun around slowly. The sonar picked up another object close by. Accelerating too quickly, he overshot the bathysphere and, turning sharply, had to come around again.

Austin hovered some twenty feet over the B3. The temperature inside the Hardsuit had dropped, yet sweat beaded his forehead. The difficulty of the task in this hostile environment having dawned on him, he knew that a mistake made in haste could be fatal. He took a deep breath, pressed the vertical-control pedal, and began his descent to the bathysphere entombed in mud below.

NUMA 8 - Medusa

CHAPTER 10

THE B3 WAS QUICKLY BECOMING A GLOBE-SHAPED FREEZER as its battery-operated heating system fought a losing battle against the deep-ocean chill. Joe Zavala and Max Kane had wrapped blankets around themselves like Navajo Indians and sat back-to-back to conserve heat. Their numb lips proved useless for speech, and their lungs labored to extract an ever-diminishing amount of oxygen from the rapidly thinning air.

Zavala dreaded the moment when the power would fail completely. He didn’t want to die in the dark. The bathysphere had an auxiliary air tank, but he wondered if it would be worth prolonging the misery. At the same time, he stubbornly fought the urge to give up, and he filled his mind with visions of the mountains around Santa Fe. Closing his eyes, he imagined he was resting after a hike in the winter, not trapped in a hollow steel ball at the bottom of the cold sea.

Clunk!

Something had thumped against the bathysphere. Zavala pressed his head against the wall, ignoring the coldness that seeped through the metal skin. He could hear a gritty, scraping sound, then another clunk, followed by several more.

Morse code for k, he realized.

Then, after an agonizing pause, he heard a.

Kurt Austin.

Kane had been sitting with his head down and hunched over his knees. Raising his chin off his chest, he glanced toward Zavala with rheumy, unfocused eyes.
