The collision brought with it a thousand cries of mechanical agony—steel grating on steel, hydraulic lines bursting, hull plates splintering, power plants imploding. As the destruction reached its climax, there was an odd moment of silence, then the wails of violence turned to the gurgling moans of mortality.

The icebreaker slowly slid free of the gaping wound, breaking off a section of the Narwhal’s stern as it backed away. The vessel’s sharp bow had been bludgeoned flat, but the ship was otherwise fully intact, its double hull not even compromised. The Otok lingered on the scene a few moments, as Zak and the crew admired their destructive handiwork. Then, like a deadly wraith, the murderous ship disappeared into the night.

The Narwhal, meanwhile, was on its way to a quick death. The ship’s engine room flooded almost instantly, tugging the stern down in an immediate list. Two of the bulkheads fronting the moon pool were crushed, sending additional floodwaters to the lower decks. Though built to plow through ice up to six feet thick, the Narwhal was never designed to withstand a crushing blow to its beam. Within minutes, the ship was half underwater.

On the bridge, Stenseth picked himself up off the deck to find the bridge a darkened cave. They had lost all operating power, and the emergency generator located amidships had also been disabled in the collision. The entire ship was now as black as the foggy night.

The helmsman beat Stenseth to an emergency locker at the rear of the bridge and quickly produced a flashlight.

“Captain, are you all right?” he asked, sweeping the beam across the bridge until it caught Stenseth’s towering figure.

“Better than my ship,” he replied, rubbing a sore arm. “Let’s account for the crew. I’m afraid we’re going to have to abandon ship in short order.”

The two men threw on their parkas and made their way down to the main deck, which was already listing heavily toward the stern. They entered the ship’s galley, finding it illuminated by a pair of battery-operated lanterns. Most of the ship’s skeleton crew was already assembled with their cold-weather gear, a look of fear etched in their eyes. A short man with a bulldog-like face approached the two men.

“Captain, the engine room is completely flooded and a section of the stern has been torn away,” said the man, the Narwhal’s chief engineer. “Water has reportedly breached the forward hold. There’s no stopping it.”

Stenseth nodded. “Any injuries?”

The engineer pointed to the side of the galley, where a grimacing man was having his left arm wrapped in a makeshift sling.

“ The cook broke his arm in a fall when she hit. Everyone else came through clean.”

“Who are we missing?” Stenseth asked, quickly counting heads and coming up two short.

“Dahlgren, and Rogers, the ship’s electrician. They’re trying to get the tender launched.”
