Bucky was standing by the rail, forgoing his bunk for a cigarette instead. Puffing on a Marlboro, he nodded at Miller, then looked up at the sky. An ever-present blanket of gray clouds floated in an airy mass yet appeared too light to dispense more than a light drizzle. Bucky peered across Hecate Strait at the green islands that bound it to the west. Ahead off the port bow, he noticed an unusually thick cloud rolling along the water’s surface. Fog was a common companion in these waters, but there was something peculiar about this formation. The color was a brighter white than that of a normal fogbank, its billows heavier. Taking a long drag on his cigarette, Bucky exhaled deeply, then walked to the wheelhouse.

Miller had already taken note of the white cloud and had a pair of binoculars trained on the mist.

“You seen it too, boss? Kind of a funky-looking cloud, ain’t it?” Bucky drawled.

“It is. I don’t see any other vessels around that could have discharged it,” Miller replied, scanning the horizon. “Might be some sort of smoke or exhaust that drifted over from Gil.”

“Yep, maybe somebody’s fish smoker blew,” the deckhand replied, his crooked teeth in a wide grin.

Miller set down the binoculars and grabbed the wheel. Their path around Gil Island led directly through the center of the cloud. Miller rapped his knuckles on the worn wooden wheel in uneasiness, but he made no effort to alter course.

As the boat approached the cloud’s periphery, Miller stared at the water and crinkled his brow. The color of the water changed visibly, from green to brown to copper red. A number of dead salmon appeared in the crimson broth, their silver bellies pointing skyward. Then the fishing boat chugged into the haze.

The men in the wheelhouse immediately felt a change in temperature, as if a cold, wet blanket had been thrown over them. Miller felt a dampness in his throat while tasting a strong acidic flavor. A tingling sensation rippled through his head, and he felt a sudden tightening in his chest. When he sucked in a breath of air, his legs buckled, and stars began to appear before his eyes. His pain was diverted when the second deckhand burst into the cabin with a shriek.

“Captain . . . I’m suffocating,” gasped the man, a ruddy-faced fellow with long sideburns. The man’s eyes bulged from his head, and his face was tinted a dark shade of blue. Miller took a step toward him, but the man fell to the deck unconscious.
