“I hadn’t thought of that,” Suzanne admitted.

“But the Cold War is over,” Perry said. “Surely we don’t have to worry about that old cloak-and-dagger stuff.”

“There are people in the Russian military who feel differently,” Donald said. “I know because I have met them.”

“So what do you think we should do at this point?” Suzanne asked.

“I think that question has just been answered for us,” Donald said. He raised his free hand and pointed over the shoulders of the others. “Look over there, in the direction we were going before the alarm sounded!”

Suzanne and Perry spun around. About a quarter of a mile away a single door was slowly opening inward into the blackness. Bright artificial light spilled from the room beyond into the dark cavern, forming a line of reflection that extended to their feet. The trio was too far away to see any interior details, but they could tell the light was intense.

“So much for the question whether the facility is manned or not,” Donald said. “Obviously, we are not alone. Now the question becomes how happy they are to see us.”

“Do you think we should walk over there?” Perry asked.

“We don’t have much choice,” Donald said. “We’ll have to go at some point.”

“Why didn’t they just come in here and meet us in person?” Suzanne asked.

“A good question,” Donald said. “Maybe it has something to do with the welcome they are planning for us.”

“I’m getting scared again,” Suzanne said. “This is very bizarre.”

“I’ve never stopped being scared,” Perry admitted.

“Let’s go meet our captors,” Donald said. “And let’s hope they don’t consider us spies-and that they are familiar with the terms of the Geneva Convention.”

Straightening himself, Donald started forward, seemingly oblivious to the mud sucking at his feet. He passed his two companions, who had to admire his courage and leadership.

Perry and Suzanne hesitated for a moment before falling in behind the retired naval commander. Neither spoke as they resignedly trudged in his footsteps toward the beckoning door. They had no idea whether it would provide deliverance or further trials, but as Donald had said, they did not have any choice.

It was slow going. At one point, Perry slipped and fell back into the mire. He was covered with the ooze.

“The first thing I’m going to do is demand a shower,” Perry sputtered trying to lighten the mood. He was not successful. No one responded.

As they approached the open door, they hoped that their misgivings would be allayed. But no welcoming figures appeared at the threshold, and the light spilling out into the darkness was so bright they were unable to see inside. It was even difficult to look at the opening without shielding their eyes.

When they got close enough, they could appreciate that the door was almost two feet thick with a ring of huge throw bolts countersunk into its periphery. It looked like a door to a vault. The edges of the massive portal were angled in. It was obviously constructed to withstand the enormous pressure of seawater flooding the cavern.

At about twenty-five feet from the wall Suzanne and Perry stopped. They were reluctant to proceed without a clearer idea of what they were getting into. They studied the door for clues. From what they could tell, it appeared as if the walls, floor, and ceiling within were constructed of stainless steel that gleamed like mirrors.

Donald had continued ahead on his own, and although he did not step over the threshold, he leaned in. With his forearm acting as a shield against the reflected light, he surveyed the room.

“Well?” Suzanne called. “What do you see?”

“It’s a large, square room made out of metal,” Donald yelled back over his shoulder. “There’s a couple of huge shiny balls in it but nothing else. There also doesn’t appear to be any door except this entrance. And I can’t tell where the light is coming from.”

“Any sign of people?” Perry asked.

“That’s a negative,” Donald said. “Hey, I think the balls are made of glass. And they must be four to five feet in diameter. Come and take a look!”

Perry glanced at Suzanne. He shrugged. “Why put off the inevitable?”

Suzanne was gripping her arms. She shuddered. “I was hoping by the time we got over here I’d have a better feeling about all this, but I don’t. This can’t be a submarine base. We’re talking about an engineering feat that would make building the Great Pyramid seem like a walk in the park.”

“Then what do you think it is?” Perry questioned.

Suzanne turned to look back toward the submersible. The light from the open door was illuminating it despite the distance. Beyond it was blackness. “I truly have no clue.”

When Donald saw that Suzanne and Perry were looking back at the submersible, he went ahead and stepped over the threshold into the room. Immediately he put his hands out to balance himself to keep from falling. A combination of the wet mud on his shoes and the polished metal made the floor as slippery as ice.

Once he had his equilibrium Donald again scanned the room. Now that his eyes had partially adjusted he could see much better, including hundreds of reflections of himself in all directions. The walls, floor, and ceiling were seamless. The only apparent door was the one he’d entered through. He specifically searched for a source of the dazzling light but mysteriously could not find any. When his line of sight took in the huge glass balls, he did a double take. He was now able to appreciate that the glass was not entirely opaque. They were clear enough to just make out what was inside.

“Suzanne, Perry!” Donald yelled. “There are a couple of people in here after all. But they’re sealed inside glass spheres. Get in here!”

A moment later Suzanne and Perry appeared at the door.

“Careful about the floor!” Donald warned. “It’s as slick as ice.”

Sliding their feet in short movements as if skating without skates, Suzanne and Perry staggered over to Donald’s side, eager for a better look at the glass spheres.

“My word!” Suzanne exclaimed. “They’re floating around in some kind of fluid.”

“Do you recognize them?” Donald asked.

“Should I?” Suzanne responded.

“I think I do,” Donald said. “I think it’s two of our divers.”

Suzanne stared at Donald in disbelief. Then, to get a better look, she cupped her hands around her eyes and leaned against one of the spheres, the surface so opalescent it reflected the room’s bright illumination.

“I think you’re right,” Suzanne said. “I can just make out the Benthic Explorer logo on the neoprene suit and the side of the helmet.”

Perry mimicked Suzanne by shielding his eyes with his hands and pressing them against the same sphere Suzanne was gazing into. Donald did likewise from another angle.

“He’s breathing!” Perry said. “He must be alive.”

“There’s something like an umbilical cord coming from some kind of device pressed up against his abdomen,” Suzanne said. “Can anybody see where it goes?”

“It goes under him,” Donald said. “To the base of the container.”

Suzanne moved away enough to allow her to bend down. The sphere had a flat area on which it sat. She did not see any penetrations, and if there were any they would have come directly through the floor.

“This is as astounding as the cavern,” Suzanne said while regaining her feet. She reached out and touched the sphere with the tip of her index finger. The material looked like glass but she was not sure what it was.

The others straightened up.

“How on earth did they get here?” Perry asked.

“A lot of questions,” Donald said, “and very few answers.”

“Are you still thinking this is some kind of military installation?” Suzanne asked Donald.

“What else could it be?” Donald demanded defensively.
