But the captain saw no signs of boredom in Zak’s face. On the contrary, there was an odd intensity about him. Like in the moment before an assassination, he was fully alert, his senses in high gear. While he had murdered many times before, he had never done so on a large scale. It was a test of cunning, he liked to think, that made his blood run fast. It gave him a sensation of invincibility, inflated by the knowledge that he had always come out on top.

“Bring us to within eight kilometers of the Narwhal,” he finally directed the captain. “And do so nice and easy.”

The captain engaged the helm and brought the ship and attached barge around on a southerly heading. Aided by the swift-moving current, the icebreaker ran just above idle, covering the distance in less than an hour. Reaching the new position, the captain swung his bow around to the current in order to remain stationary.

“Eight kilometers and holding,” he reported to Zak.

Zak eyed the gloomy darkness outside the bridge window and creased his lips in satisfaction.

“Prepare to release the barge at my command,” he said.

The captain stared at him as if he were insane.

“What are you saying?” he asked.

“You heard me. We are going to release the barge.”

“ That’s a ten-million-dollar vessel. In this fog and current, there’s no way we’ll be able to tie back up to her. She’ll rip her hull open on some ice or run aground on the islands. Either way, Mr. Goyette will have my head.”

Zak shook his head with a thin smile. “She won’t be traveling very far. As for Goyette, please recall the signed letter I gave you in Kugluktuk giving me complete authority while I’m aboard this ship. Believe me, he will consider it a small price to pay to eliminate a problem that could cost him hundreds of millions of dollars. Besides,” he added with a conniving grin, “isn’t that what marine insurance is for?”

The captain reluctantly ordered his deckhands to the stern of the ship to man the towlines. The men waited in the cold while Zak ran down to his cabin, then returned to the bridge carrying his leather satchel. At Zak’s command, the captain reversed power and backed down on the barge until the thick towlines fell slack in the water. The deckhands released a lock plate, then heaved the looped ends of the towlines up and off the stern bollards. The men watched morbidly as the lines slid down the stern and disappeared into the black water below.
