Crozier is dreaming about the picnic to the Platypus Pond and of Sophia stroking him under water when he hears the sound of a shot and comes crashing awake.

He sits up in his bunk not knowing what time it is, not knowing if it is day or night, although there is no line between day and night any longer since the sun has disappeared this very day, not to reappear until February. But even before he lights the small lantern in his berth to check his watch, he knows that it is late. The ship is as quiet as it ever gets; silent except for the creak of tortured wood and frozen metal within; silent except for the snores, the mumbles, and the farts from the sleeping men, and curses from Mr. Diggle the cook; silent save for the incessant groaning, banging, cracking, and surging of the ice outside; and, added to those exceptions to silence this night, silent but for the banshee screech of a high wind.

But this is no sound of ice or wind that wakes Crozier. It is a gunshot. A shotgun – muffled through the layers of oak planks and overlaying snow and ice, but a shotgun blast without doubt.

Crozier was sleeping with most of his clothes on and now has pulled on most of the other layers and is ready for his cold-weather slops when Thomas Jopson, his steward, knocks on the door with his distinctive soft triple rap. The captain slides it open.

“Trouble on deck, sir.”

Crozier nods. “Who’s on watch tonight, Thomas?” His pocket watch shows him that it is almost 3:00 a.m., civilian time. His memory of the month’s and day’s watch schedule gives him the names an instant before Jopson speaks them aloud.

“Billy Strong and Private Heather, sir.”

Crozier nods again, lifts a pistol from his cupboard, checks the priming, sets it in his belt, and squeezes past the steward, out through the officers’ dining cubicle that borders the captain’s tiny cabin on the starboard side, and then quickly forward through another door to the main ladderway. The lower deck is mostly dark at this time in the morning – the glow around Mr. Diggle’s stove the primary exception – but lamps are being lit in several of the officers’, mates’, and stewards’ quarters as Crozier pauses at the base of the ladder to pull his heavy slops from the hook and struggle into them.

Doors slide open. First Mate Hornby walks aft to stand next to Crozier by the ladder. First Lieutenant Little hurries forward down the companionway, carrying three muskets and a saber. He’s followed by Lieutenants Hodgson and Irving, who are also carrying weapons.

Forward of the ladder, seamen are grumbling from deep in their hammocks, but a second mate is already turning out a work party – literally tumbling sleeping men from their hammocks and shoving them aft toward their slops and the waiting weapons.

“Has anyone been up top yet to check out the shot?” Crozier asks his first mate.

“Mr. Male had the duty, sir,” says Hornby. “He went up as soon as he sent your steward to fetch you.”

Reuben Male is captain of the fo’c’sle. A steady man. Billy Strong, the seaman on port watch up there, has been to sea before, Crozier knows, on HMS Belvidera. He wouldn’t have shot at phantoms. The other man on watch was the oldest – and in Crozier’s estimation, the stupidest – of the surviving Marines, William Heather. At age 35 and still a private, frequently sick, too often drunk, and most frequently useless, Heather had almost been sent home from Disko Island two years before when his best friend Billy Aitken was discharged and sent back on HMS Rattler.

Crozier slips the pistol into the oversized pocket of his heavy woolen outer coat, accepts a lantern from Jopson, wraps a comforter around his face, and leads the way up the tilted ladder.

Crozier sees that it is as black as the inside of an eel’s belly outside, no stars, no aurora, no moon, and cold; the temperature on deck registered sixty-three degrees below zero six hours earlier when young Irving had been sent up to take measurements, and now a wild wind howls past the stubs of masts and across the canted, icy deck, driving heavy snow before it. Stepping out from beneath the frozen canvas enclosure above the main hatch, Crozier holds his mittened hand alongside his face to protect his eyes and sees a lantern gleam on the starboard side.

Reuben Male is on one knee over Private Heather, who is lying on his back, his cap and Welsh wig knocked off and, Crozier sees, part of his skull knocked away as well. There seems to be no blood, but Crozier can see the Marine’s brains sparkling in the lantern light – sparkling, the captain realizes, because there is already a sheen of ice crystals on the pulped grey matter.

“He’s still alive, Captain,” says the fo’c’sle chief.

“Jesus fucking Christ,” says one of the crewmen crowded behind Crozier.

“Belay that!” cries the first mate. “No fucking profanity. Speak when you’re fucking spoken to, Crispe.” Hornby’s voice is a cross between a mastiff’s growl and a bull’s snort.

“Mr. Hornby,” says Crozier. “Assign Seaman Crispe to get below double-quick and bring up his own hammock to carry Private Heather below.”

“Aye, sir,” say Hornby and the seaman in unison. The pounding of running boots is felt but goes unheard over the wind screech.

Crozier stands and swings his lantern in a circle.

The heavy railing where Private Heather was standing watch at the base of the iced-over ratlines has been smashed away. Beyond the gap, Crozier knows, the heaped ice and snow runs down like a toboggan ramp for thirty feet or more, but most of that ramp is not visible in the blinding snow. There are no prints visible in the small circle of snow illuminated by the captain’s lantern.

Reuben Male lifts Heather’s musket. “It wasn’t fired, Captain.”

“In this storm, Private Heather couldn’t have seen the thing until it was right on him,” says Lieutenant Little.

“What about Strong?” asks Crozier.

Male points toward the opposite side of the ship. “Missing, Captain.”

To Hornby, Crozier says, “Choose a man and stay with Private Heather until Crispe is back with the hammock and carry him below.”

Suddenly, both surgeons – Peddie and his assistant, McDonald – appear in the circle of lamplight, McDonald wearing only light slops.

“Jesus Christ,” says the chief surgeon, kneeling next to the Marine. “He’s breathing.”

“Help him if you can, John,” says Crozier. He points to Male and the rest of the seamen crowding around. “The rest of you – come with me. Have your weapons ready to fire, even if you have to take your mittens off to do it. Wilson, carry both those lanterns. Lieutenant Little, please go below and choose twenty more good men, issue full slops, and arm them with muskets – not shotguns, muskets.”

“Aye, sir,” Little shouts over the wind, but Crozier is already leading the procession forward, around the heaped snow and vibrating canvas pyramid amidships and up the canted deck toward the port lookout station.

William Strong is gone. A long wool comforter has been shredded, and the tatters of it, caught in the man lines here, are flapping wildly. Strong’s greatcoat, Welsh wig, shotgun, and one mitten are lying near the railing in the lee of the port privy where men on watch huddle to stay out of the wind, but William Strong is gone. There is a smear of red ice on the railing where he must have been standing when he saw the large shape coming at him through the blowing snow.

Without saying a word, Crozier dispatches two armed men with lanterns aft, three more toward the bow, another with a lantern to look beneath the canvas amidships. “Rig a ladder here, please, Bob,” he says to the second mate. The mate’s shoulders are hidden under heaps of fresh – that is, not yet frozen – rope he’s carried up from below. The ladder goes over the side within seconds.
