Blakely glanced over his shoulder to face the geologist. "We'll reach the shaft elevators in about ten minutes. Be at Alpha Base by dinner. So relax. Enjoy the ride."

Khalid nodded, and Blakely watched the Egyptian return to studying the passing lamps and cables, his dark eyes taking in all the details.

Swinging back in his seat, Blakely understood the geologist's edginess. This waiting gnawed at one's nerves.

Ashley stretched muscles cramped by the ride. She glanced back as the second Sno-Cat trundled into the large cavern and discharged its passengers, then returned her attention to the massive elevator-a cage of iron bars.

Jason was exploring around the huge crates that filled the back half of the cave. He looked like a mouse scurrying among a child's spilled toy blocks. "Jason!" she called. "Stay close, hon."

Her son waved his acknowledgment.

Blakely, enlisting Ben's aid, waved toward the elevators. "Help me with these doors."

Ben and Major Michaelson hauled the doors aside so the crew could enter. Jason had wandered over. Ben tousled his hair. "Ready for this, mate?"

Jason grinned as he entered the garage-sized elevator, big enough to park both Sno-Cats. "Oh, yeah. This is so awesome."

Ashley eyed the interior of the elevator. The ceiling and floor were sheets of solid red iron, but the walls were just one-inch-thick iron bars. Like a gigantic birdcage.

"We'll travel about the equivalent of two hundred floors," Blakely said as the doors closed. "Took three years alone to mine out this six-hundred-meter shaft that separates the floor of this rift from the cavern below." He yanked a lever, and Ashley felt the familiar lurching as the elevator dropped with a rumble.

She held Jason's hand. How safe was this contraption? She voiced her concerns.

Blakely smiled. "We've hauled heavy machinery with this elevator. Even several trucks. It'll hold the group of us just fine." He tapped the metal wall of the cage. "This is the lifeline of Alpha Base. It's maintained like an expensive Swiss watch and guarded like the crown jewels."

Ashley noticed Khalid's smile. Amused at her feminine fears, she thought. Just another macho man, fearless in the face of reason. She watched him as he eyed the cage, studying it.

An uncomfortable silence took hold as the team continued their descent. The only illumination came from a single lamp in the ceiling of the cage. It felt like they were suspended in space.

Feeling the need to break the silence, Ashley turned to Blakely. "You know," she said, "something has been bothering me. And I imagine a few of the others too."

"Hmmm?" He seemed lost in reverie.

Ben perked up, pushing off the wall he had been leaning on. The others too were staring at them with interest.

"Let's be honest here," she said. "Are we here to investigate this continent or rape it?"

Blakely's eyebrows arched.

"We all know science doesn't pay"-she waved at the steel cage-"this well. More's at stake than just an archaeological investigation."

"True," Blakely said, taking off his glasses and rubbing at the bridge of his nose, "but let me assure you, first and foremost I am a scientist. To me, the mission has been and always will be a scientific one. That is one of the reasons I chose you to head this team, Professor Carter. I want this mission to remain a scientific venture. But we don't live in a vacuum. This mission does have some significant economic and political ramifications."

Blakely added, "Don't be so quick to judge. It gets the bills paid. Gets me my equipment." He pointed at the others, then at her. "And it gets me a prime team."

"Still," she said, "what's the final tradeoff for this exploration? If we end up with a strip-mined and blasted continent… that's too hefty a price tag. I can live without answering the mystery of the caverns."

He stared at her, a sad look on his face. "Can you really, Professor Carter?"

She opened her mouth to declare her convictions, but the lie would not come out. She had asked Blakely to be honest. Could she be any less? She remembered the diamond figurine, glowing in the last rays of the setting sun. She closed her mouth. Damn.

He nodded and pointed down. "Here it comes."

Just then a breeze rushed into the cage, blowing back her parka hood. A warm breeze! At the same time, light burst up from below. The elevator had just dropped into the cavern.

The ceiling of the cave, illuminated from below, dripped with damp stalactites, huge mountains hanging upside down. Several reached to the floor to form gigantic pillars. A natural colonnade. The elevator was descending beside a pillar twice the diameter of their own cage. Ashley noticed someone had scrawled graffiti on the column. An arrow pointing down with the rough-lettered words, "Hell… one mile!"

Ben frowned. "Defacing a cavern. That's not only poor taste, but among cavers it's considered bad luck."

Blakely scowled at his assistant Roland. "Let's get that removed-today."

Ashley shook her head; droplets flew from the tip of her nose. She wiped her brow. Damp. The humidity must be close to a hundred percent. But the air! She inhaled deeply. It was so clean.

She squinted, but the far wall was blocked by the massive pillar. Damn. She had hoped to spy the dwellings.

"Mom! Look!" Jason pointed toward the cavern floor.

Sighing in exasperation, she stood on tiptoe, leaning her forehead against the cold bars. Below, buildings and tents dotted the floor, lit by searchlights and festooned with lamps. A deep chasm, like a black wound, cut the base in two. A lighted bridge crossed the gap, linking the two halves. It was their destination.

Alpha Base.

"Look over here," Linda exclaimed. "You can see fish!"

Ashley sidled behind Linda, placing a hand on her shoulder, peering over and down.

At the edge of Alpha Base, reflecting the lights of the camp, was a mammoth lake, covering several hundred acres, rippling gently. From above, a few glowing residents of the lake could be seen gliding and darting under the glassy surface. Strangely poetic.

"Cool," Jason exclaimed.

"And how, mate." Ben nudged Ashley with an elbow. "Amazing, ain't it?"

Ashley nodded, her mind numb. Anxious to explore, her qualms from a moment ago were a dim memory. "Am I remembering correctly? Did you say the cavern was five miles across?

Blakely nodded, a smile playing about his lips. "Approximately."

Ben whistled.

Within minutes, the cage settled to the cavern floor, secure in its berth. A uniformed escort stood ready to guide them to their quarters. Blakely faced the group. "We're home!"

Alpha Base, Antarctica

ASHLEY WATCHED WITH A SMIRK AS JASON DARTED around his bedroom. Her own room in the two-bedroom suite was just as impressive. Hard to believe each member of the team had a separate suite in the main dormitory of the base. The perks of working on this mission were getting better and better. Lace curtains, walnut desks, thick upholstered chairs, designer wallpaper. Who would have thought they were two miles underground?

"Look, Mom." He pointed to a desk in the corner of his room. "A real Pentium II. Not one of those slowpoke clones."

She hated to burst his balloon, but he had to learn sometime. "That's for your homework."

Jason turned to her, his jaw hanging open. "It's the beginning of summer, Mom!"

"It's only a couple hours each day. While I'm gone, I want you to put this time to use. There's a library on the base. I want you to check out two books while I'm gone and write a book report on each."
