Haynes never lifted his eyes from the charts. “Done wearing out my decks?” he asked.

“For now,” Kurt replied. “But we’re going to need to change course to one-nine-zero.”

The captain looked up briefly and then back down at the chart table. “I told you before, Kurt, you lose something over the side, you’re going to have to swim for it if you want it back.”

Kurt smiled briefly, but the situation was serious.

“There’s a line of smoke off our starboard beam,” Kurt said. “Someone’s got a fire going, and I don’t think it’s a barbecue.”

The captain stood straight, the joking look gone from his face. A fire at sea is an incredibly dangerous event. Ships are filled with pipes and conduits that carry flammable liquids like fuel and hydraulic fluid. They often carry dangerous and even explosive cargoes: oil, natural gas, coal, and chemicals, even metals like magnesium and aluminum that burn. And unlike a fire on land, there’s really nowhere safe to run unless you abandon ship, the last option in any captain’s handbook.

Kurt knew this, as did every man on the Argo. Captain Haynes didn’t hesitate or even attempt to confirm the accuracy of Kurt’s assessment. He turned to the helmsman.

“Take us around,” he said. “Make your course one-nine-zero. Bring us to flank speed.”

As the helmsman executed the order, the captain grabbed a pair of binoculars and headed out onto the starboard wing of the bridge. Kurt followed.

The Argo was fairly close to the equator, and at such latitudes the light grew quickly. Kurt could see the smoke plainly now, even without the binoculars. Thick and dark, it rose skyward in a narrow vertical column, thinning out only marginally on the way up and drifting slightly to the east.

“Looks like a cargo vessel,” Captain Haynes said.

He handed the binoculars to Kurt.

Kurt trained them on the ship. She was a midsize vessel, not a containership but a bulk carrier. She appeared to be adrift.

“That’s oil smoke,” Kurt said. “The whole ship is shrouded in it, but it’s thickest near the aft end.”

“Engine-room fire,” Haynes said. “Or a problem with one of the bunkers.”

That would have been Kurt’s guess as well.

“Did you pick up any distress calls?”

Captain Haynes shook his head. “Nothing. Just regular chatter on the radio.”

Kurt wondered if the fire had taken out her electrical system. But even if it had, most ships carried backups, and every vessel of that size would have a few handheld transceivers, an emergency beacon, and even radios in the main lifeboats. To hear nothing from a 500-foot vessel burning and adrift seemed all but impossible.

By now the Argo had finished its turn and was heading dead at the stricken ship. Her speed was coming up, and Kurt could feel them surging through the water. The Argo could make 30 knots in calm seas. Kurt guessed the range at just over five miles, closer than he’d first thought. That was a good thing.

But ten minutes later, as he trained the binoculars on the superstructure and increased the magnification, he spotted several things that were less than good.

Flames were licking out through various hatches all along the deck, meaning the entire vessel was burning, not just the engine room. The ship was definitely listing to port and was down at the bow, meaning she was taking on water as well as burning. But worst of all, there were men on the decks who seemed to be dragging something toward the rail.

At first Kurt thought it was an injured crewman, but then they let go of the person, dropping him to the deck. The man tumbled as if he’d been shoved and then got up and began to run. He made three or four steps, only to fall forward suddenly onto his face.

Kurt snapped the binoculars to the right just to be sure. He could clearly see a man holding an assault rifle. Without a sound he saw the muzzle flash. One burst and then another.

Kurt turned back to the man who’d fallen. He lay utterly still now, facedown on the deck.

Pirates, Kurt thought. Hijackers with assault rifles. The cargo vessel was in deeper trouble than he’d guessed.

Kurt lowered the binoculars, fully aware that they were now heading toward more then a rescue.

“Captain,” he said. “Our problems just multiplied.”

ABOARD THE KINJARA MARU, Kristi Nordegrun struggled with the darkness. Her ears rang with a strange sound, and her head pounded as if she’d been drinking all night. She lay on the floor, her limbs stiff and folded under her in an awkward tangle.

Try as she might, she could not even remember how she’d gotten there, let alone what had happened. Based on the numbness in her legs, she guessed she had been in that position for a long time.

Unable to stand yet, Kristi propped herself up against the wall, fighting an unbalanced equilibrium.

She was in the deepest part of the crew’s quarters, several flights below deck and near the center of the vessel. She’d come here because the mess was on this deck and she was going to meet her husband for a late meal before they retired for the night. She looked around but didn’t see him. That concerned her.

If she had been knocked unconscious for some time, surely her husband would have found her. Then again, if the ship was in trouble, his first duty was as captain.

Kristi realized she could smell smoke. She couldn’t remember an explosion, but the ship was definitely on fire. She remembered her husband telling her there were some waters of the world where terrorists planted mines. But it seemed not to concern him on this journey.

She tried again to stand, fell to the side, and knocked over a table upon which cans of soda stood. In the darkness she heard a strange sound, like marbles rolling around.

The noise moved away from her but continued until ending with several dull clunks. At that moment Kristi realized what had happened: the cans were rolling away from her, gathering speed until they hit the bulkhead.

Her equilibrium was definitely off, but so was the floor. The ship was tilting, listing. Panic gripped her. She knew now that the ship was sinking.

She crawled to the wall, bumped into it, and then followed it to the door. She pushed on the door. It moved a few inches and then hit something soft. She pushed again, leaning her shoulder into it and shoving it a few more inches. Trying to squeeze through, she realized the object blocking her way was the body of a man, lying against the door.

As she pushed, the man moved a fraction, rolling over and moaning.

“Who are you?” she said. “Are you hurt?”

“Mrs. Nordegrun,” the man managed to say.

She recognized the voice, one of her husband’s crew members from the bridge. A nice man, from the Philippines, her husband had said he’d be a good officer one day.

“Mr. Talan?”

He sat up. “Yes,” he said. “Are you okay?”

“I have no balance,” she said. “I think we’re sinking.”

“Something happened,” he said. “We have to get off the ship.”

“What about my husband?”

“He’s on the bridge,” Talan said. “He sent me for you. Can you make it to the stairs?”

“I can,” she said. “Even if I have to crawl.”

“Is better that way,” he said, finding her hand and guiding her in the right direction.

“Yes,” she agreed. “We need to stay underneath the smoke if we can.”

Before getting married, Kristi had been a paramedic and then a trauma nurse. She’d been on the scene of many accidents and fires and even a building collapse. And despite her fear and confusion, her past training and experience were kicking in and taking over.

Together, they began crawling along the floor. Fifty feet on, they found another crewman, but they could not wake him.
