They would never be found at sea.

Sebastian Panos made his way through the narrow corridor like an alley cat on a dark street behind restaurant row. The passage was dank and wet, more like a sewer tunnel than a gangway. Condensation dripped so persistently that he often wondered if the poisonous waters from outside the submerged station were leaching through the walls and slowly killing them all.

Still, it wasn’t as bad as the island where the main work was done, with the notorious quarry at its heart. Compared to that place, this station was a pleasure. And yet, Panos had become obsessed with thoughts of escape.

A Cypriot engineer of mixed Greek and Turkish background, Panos had been lured to this underwater nightmare by the promise of a big contract and enough money to set his family up for a generation. All it required was three years of his life and utter secrecy. Six months in, he’d begun to feel uneasy. Before the year rolled over, he knew he’d made a terrible mistake.

Requests to leave were denied. All communications were monitored and often interrupted. The slightest hint of protest resulted in veiled threats. Something might happen to his family if he didn’t stay and complete the work.

As the project neared fruition, Panos and the other engineers were played off against one another. It was impossible to know who to trust and who to fear, so they feared one another, did as they were told, and one year stretched into two.

All that time Panos lived like a sailor press-ganged onto a ship. He had no choice but to do the master’s bidding or forfeit his life, though he felt certain that his end would come that way eventually. The project was so secret and dark that his logical mind told him there would be no witnesses left when it was done.

No one gets out alive, a fellow worker had joked. One day later, the man disappeared, so perhaps it was true.

Panos remembered an offer to bring his family along. He wasn’t a religious man, but he thanked whatever god or fate or random instinct had caused him to decline. Others had brought their families in. He’d seen them on the island, wretched and miserable, prisoners to an even greater degree than he. He knew not to trust them. They were the easiest to control, they had more to lose than their own lives. Some had even borne children in the depths of that putrid, sulfur-tinged world. They lived like indentured servants, like slaves building a modern-day pyramid.

Panos was at least free to think about escape, though he’d never had any real expectation of pulling it off. At least, not until the note appeared in his locker.

It was the first in a set of mysterious contacts from an unseen angel of mercy.

Initially, he assumed it was a trap, a little test to see if he would lunge at the bait. But he’d reached a point where it no longer mattered. Freedom beckoned. Whether it came through escape or the cold sting of death, he welcomed it either way.

He tested the offer and received more notes. They arrived at odd times. Help to escape would be made available, the notes promised, but it would come with strings attached. He was to bring the plans of this terrible weapon to those who might stop the madman constructing it. A drop had been arranged. All Panos had to do was make it to the location alive.

With that goal in mind, he continued down the wet gangway and into the dive room. It was late, well past the hour for anyone to be there. Using a key left in his locker by his unknown contact, Panos opened the door and slipped inside. He shut the door and switched on a desk lamp.

The dive room was a twenty-by-forty rectangle with a sealed airlock protruding at its center. Visible through the airlock’s thick observation glass was a circular pool of dark water.

Panos switched on the pool lights. The water lit up perfectly clear, for the poisons filling it made it absolutely sterile. But instead of blue or turquoise or green, the water shimmered in a reddish tint, a color like translucent blood.

He took a deep breath. He would be all right. The dry suit would keep the toxins out. At least he hoped it would.

He glanced over at a whiteboard. Three numbers had been scrawled on it: 3, 10, and 075. His unseen helper had been there before him, just as he’d promised.

Panos memorized the figures and then quickly erased them. He went to the third locker and opened it. A dry suit and an oxygen tank had been prepared for him. A dive watch, hanging with the suit, had its bezel twisted to the ten-minute mark. This was the time it would take him to ascend, moving at thirty feet per minute, a pace calculated to help him avoid the bends. A handheld compass had also been left for him. When he surfaced, he would look to a heading: 075 degrees. In that direction, he would find help.

A dive knife would be his only weapon, if he needed it.

He strapped the watch around his wrist and carried the tanks to the airlock. He slipped the compass into his pocket and then double-checked that the cargo he’d promised to carry — the schematics of the station and a portable hard drive filled with data — were secured in a watertight container.

He shoved them back inside his shirt and grabbed the bulky suit, sitting down to pull it on. Before he could get a leg in, a clicking noise sounded from across the room.

A key in the lock.

The handle turned and the door swung open. Two figures stepped in, chatting between themselves.

For a second, they didn’t notice Panos. When they did, they looked more confused and surprised than angry. But Panos knew the suit and tanks would give him away.

He charged the men before they could react, swinging the knife downward at the closest figure, stabbing the man in the shoulder. The man fell back, grabbing at Panos and dragging him to the desk. The second man jumped on him, putting an arm around his neck.

Panos reared up and forced himself backward until the two of them collided with the desk, fell to the ground, and separated.

Spurred on by adrenaline, Panos was up first. He kneed the man in the face, then grabbed the desk lamp and slammed it into the man’s forehead. The man hit the ground and didn’t move again, but the one who’d been stabbed was running out the door.

“No!” Panos exclaimed.

With no way to barricade the door and precious little time before an alarm sounded, he made a fateful decision. He left the dry suit on the floor and stepped into the airlock. Pressing a switch, he closed the inner door and began to pull on the harness and an oxygen tank.

Panos felt his ears popping as a hissing noise told him the airlock was sealed and being pressurized. Even though the station’s pressure was twice the normal atmosphere, it wasn’t enough to keep the water from flooding in through the open pool. Thus, the airlock was needed.

He pulled on the dive helmet. The seal wasn’t too bad. He made sure the air was flowing, pulled his fins on, and dropped into the glowing red water.

Stillness surrounded him. He swam downward, away from the light, and out into the dark. When he’d passed the edge of the submerged structure, he began to kick his way upward. Or what he thought was up.

Three hundred feet down, there was no light. He quickly became disoriented. Vertigo set in, and it seemed like his body was doing summersaults even though he was completely still.

Flicking on a light did little good. The red water gave nothing away. He began to panic, knowing men from the station would be following him soon.

What had he done?

He exhaled a cloud of bubbles. Quite by accident, he noticed the direction they raced off in. It seemed to Panos that the bubbles were traveling sideways, but his rational mind knew this was not the case. The bubbles could only be moving upward. The laws of nature could not be altered or tricked like his sense of balance.
