The Silent Deep

Day forty-seven. The watch rotation changed at 0600. Hank Hansen walked the corridor from his quarters to the conn. The corridor was narrow—just wide enough for two men to pass if one stepped back. The bulkhead panels were painted a color that was not white and not gray but something the Navy had called "bulkhead" and meant it as a shade. The fluorescent lights hummed at a frequency that was just below hearing. The air tasted like recycled water and machine oil.

He entered the conn. The submarine's control room was warm and smelled of coffee. Chief Petty Officer Tommy Russo sat at the sonar console, wearing headphones, his eyes fixed on a screen that showed nothing but colored lines moving across a dark background.

"Morning, Commander."

"Morning, Chief. Contacts?"

"Nothing clean. A whale pack, forty miles southwest. Commercial traffic, probably a container ship, way out east. And the hum."

"The hum?"

"The hum." Tommy tapped his screen. "Reactors. Pumps. The ship itself. It's always there."

Hank nodded. He sat in the captain's chair. The chair was worn—his shape was molded into the padding from twenty-six years of sitting in it. He looked at the periscope mast—retracted, of course. They were at two hundred feet, deep enough that the surface was a memory and shallow enough that the pressure was a conversation rather than a threat.

"Frank?" he asked.

"Sleeping," Tommy said. "Woke up at 0500, made coffee, went back to bed. Said he'd be up by 0700."

"Copy."

Hank sat in his chair and listened to the ship. He could identify components by sound—the reactor's primary circulation pumps at a steady B-flat, the air scrubbers cycling on and off like breathing, the propulsion motor's low, continuous thrum. The submarine was a living thing. He had said this before, to people who thought he was being poetic. He was not. He was being literal. A ship this complex, this alive with machinery and human presence, was more organism than machine.

He had not seen the surface in forty-seven days.

The surface was where the world was. The world was news and weather and emails and his daughters' last three letters, which he kept in a plastic sleeve in his locker. He had read them so many times that the words had worn thin. The handwriting of fourteen-year-old Sarah was loopy and impatient. The handwriting of eleven-year-old Emily was careful and neat. Both had asked when he was coming home. Both had stopped asking and started telling him about their lives instead.

"Commander," Tommy said. "I've got something."

Hank leaned forward. On Tommy's screen, a new blip had appeared—slow, deep, moving north at perhaps five knots. The acoustic signature was unusual: not a whale, not a commercial vessel, not the ship itself. Something else.

"Classification?"

"Negative on all known profiles. Could be another submarine. Could be... something we're not trained to recognize."

"Depth?"

"Deep. Eight hundred, maybe a thousand feet. Below us."

Hank felt a small tightening in his chest. They were alone in this patch of the South Atlantic. No friendly vessels. No known hostile presence. Just a blip on a screen eight hundred feet below them, moving slowly north, making a sound that didn't match anything in the database.

"Record it," Hank said. "Log it. Keep tracking. And Chief?"

"Yes, Commander?"

"Don't broadcast it."

Tommy understood. The submarine's internal communications were on a closed loop—crew only, no external transmission. But there were protocols about reporting unusual contacts, and those protocols required transmitting data to Command.

"Understood," Tommy said. He logged the contact internally but did not send the external report.

Hank turned back to the periscope—useless at two hundred feet, but it was where captains looked when they needed to think. The periscope showed nothing. It always showed nothing.

Frank Delaney entered the conn at 0715, carrying a mug of coffee and wearing the expression of a man who had slept poorly and was pretending he hadn't.

"Morning," Frank said. "We have a visitor."

"Visitor?"

"Dr. Price. He says he needs to confer with you about the cargo."

The cargo. The sealed container in the special payload bay. Hank had not opened it. He was not authorized to open it. The men who had loaded it at port had worn hazmat suits and carried no identification and spoke no words beyond confirming that the container was secure and would remain secure until delivery.

"Tell him I'll be there after morning watch," Hank said.

Frank nodded and left. Hank watched him go—a man he had known for twenty-four years, since Annapolis, a friend who had become a colleague who had become the person who covered his weaknesses and he covered his. Frank was the executive officer. His job was to think five moves ahead. Today, he was probably thinking: who is Dr. Price, what is in the cargo, why are we alone in the South Atlantic, and when does this end?

Morning watch passed. Hank walked to the special payload bay—an isolated compartment at the rear of the submarine, accessed through two sealed doors and a security checkpoint. Dr. Alan Price was waiting for him inside the outer door, wearing a white lab coat and carrying a clipboard.

"Commander," Price said. He was fifty years old, thin, with gray hair and eyes that looked through people rather than at them. "Thank you for seeing me."

"Doctor. What do you need?"

"The cargo requires monitoring. Temperature, humidity, structural integrity. I need to access it every twelve hours."

Hank looked at the sealed container. It was a cylinder, maybe three feet long and two feet in diameter, made of a matte-black material that absorbed light rather than reflecting it. It sat on a specialized mount that isolated it from the submarine's vibration. It looked like nothing and everything at once.

"You open it?"

"No. I monitor it from the outside. The container is sealed until delivery coordinates are reached. At that point, you will receive further instructions via encrypted burst transmission."

"And the instructions will tell me to open it?"

"They will tell you what to do."

"What's in it, Doctor?"

Price looked at him with those flat, distant eyes. "I cannot answer that question. I am not cleared to discuss cargo contents with you. My role is to ensure the container remains stable. Your role is to deliver it. We are both doing our jobs, Commander. That is all."

Hank held his gaze for a moment. Then he nodded. "Twelve-hour checks. I'll make sure the deck is cleared for you."

He turned and left. Behind him, Dr. Price stood in front of the sealed container and did not open it. He stood there, looking at it, and for a moment—just a moment—Hank thought he saw the scientist's hand tremble.

Then the door sealed behind him, and the moment was over.

Day sixty-three. The radio spoke.

"Neptune, this is Overwatch. Maintain position. Await further instructions."

Hank was in the conn. Frank was beside him. Tommy was at sonar. The radio's voice was flat and mechanical—a synthesized transmission from Command, encrypted and automated.

"Overwatch, this is Neptune. Copy. What is our mission?"

Silence. Then: "You know what your mission is, Commander."

"Overwatch, I need clarification on my—"

"Neptune, maintain radio silence. Await burst transmission. Overwatch out."

The radio went dead. Frank was looking at Hank. Tommy was staring at his screen.

"Well," Frank said quietly. "That was helpful."

Hank didn't answer. He sat in his chair and thought about the last sixty-three days. Forty-seven days of nothing. Six days of a blip on a screen. Three days of Dr. Price standing in front of a black cylinder. And now this—orders that confirmed nothing and instructed in nothing.

The burst transmission came four hours later. Encrypted. Decoded by the communications officer. Delivered to Hank in a sealed envelope.

He opened it in his quarters and read:

DELIVER CARGO TO COORDINATES 34-22-S 18-47-W. UPON ARRIVAL, AWAIT FURTHER INSTRUCTIONS. DO NOT ENGAGE. DO NOT TRANSMIT. STAND BY.

Hank read it three times. Then he folded the paper and put it in his pocket. He plotted the course. The coordinates were in the middle of the South Atlantic—hundreds of miles from the nearest shipping lane, the nearest land, the nearest anything. Just open ocean.

He told Frank: "We're heading south-southwest. Four days to the coordinates."

Frank: "And then?"

Hank: "Then we stand by."

The submarine sailed. The crew ate and slept and played cards and watched DVDs and tried not to think about the fact that they were moving toward the middle of nowhere with a sealed container and orders that said stand by. Stand by for what? No one asked. They were soldiers and sailors and scientists. They followed orders.

Kid Williams stood guard in the payload bay on the third day. He was nineteen years old, from a town in Montana with a population of 847 people, and he had never been farther from home than Denver. He stood in front of the black cylinder and thought about his mom. He thought about writing her a letter. He didn't.

On the fourth day, the submarine reached the coordinates.

Hank surfaced. The conn opened. Salt air flooded in—real air, not recycled, smelling of ocean and wind and nothing else. The ocean around them was blue and empty. No land. No ships. No horizon except the one where the ocean met the sky in a line that was the same everywhere on Earth.

Dr. Price stood beside Hank at the rail. He looked out at the empty water and said nothing.

"Doctor," Hank said. "Do you know what's at the bottom of this spot?"

Price shook his head. "Ocean floor. About three miles down."

"So we're standing by in the middle of three miles of water for no reason."

"No reason that you or I will understand."

Hank nodded. He opened the sealed container.

Inside was nothing that he could identify. A cylinder of matte-black material. Sealed. Heavy. He did not open it further. He read the next set of instructions, which had arrived via another burst transmission while they were surfacing:

RETURN TO BASE. STAND BY. DO NOT DISCUSS.

That was it. Return. Stand by. Do not discuss.

Hank closed the container. He told the crew to submerge. The conn sealed. The ocean swallowed the submarine again. They sank beneath the surface, past the sunlit zone, past the twilight, into the dark where the only light was the submarine's own and the only sound was the hum of machines and the breathing of one hundred and sixty men and women who had spent ninety-one days in a metal tube and knew, with the quiet certainty of people who had never been allowed to know, that they would never understand why they had been there.

Tommy listened to the sonar. The ocean was quiet. A whale pack, far to the west. Commercial traffic, far to the east. The hum of the ship.

Kid looked at the water from the inside. It was just water. It had always been just water.

Hank sat in his chair and thought about his daughters. He would see them in three weeks. They would have grown. They would have new hobbies and new friends and new reasons to be impatient with him. He would hold them and they would feel smaller than he remembered and he would understand that time had passed while he was gone and he would not blame them for it.

The submarine sank deeper into the silent deep, and the ocean closed over it like a book being shut, and nothing in the world above or below knew that it had been there at all.
