Crozier leads the way down.

There is more blood on the ice and snow heaped along the exposed port-side hull of the ship. Streaks of blood, looking quite black in the lantern light, lead out beyond the fire holes into the ever-changing maze of pressure ridges and ice spires, all more sensed than seen in the darkness.

“It wants us to follow it out there, sir,” says Second Lieutenant Hodgson, leaning close to Crozier so as to be heard over the wind howl.

“Of course it does,” says Crozier. “But we’re going anyway. Strong might still be alive. We’ve seen that before with this thing.” Crozier looks behind him. Besides Hodgson, only three men had followed him down the rope ladder – all the rest were either searching the upper deck or were busy hauling Private Heather belowdecks. There is only one other lantern here besides the captain’s.

“Armitage,” Crozier says to the gunroom steward, whose white beard is already filled with snow, “give Lieutenant Hodgson your lantern and you go with him. Gibson, you remain here and tell Lieutenant Little where we’ve headed when he comes down with the main search party. Tell him for God’s sake not to let his men fire at anything unless they’re sure it’s not one of us.”

“Yes, Captain.”

To Hodgson, Crozier says, “George, you and Armitage head out about twenty yards that way – toward the bow – then stay parallel to us as we search south. Try to keep your lantern within sight of ours.”

“Aye, aye, sir.”

“Tom,” Crozier says to the only remaining man, young Evans, “you come with me. Keep your Baker Rifle ready but only at half-cock.”

“Aye, sir.” The boy’s teeth are chattering.

Crozier waits until Hodgson reaches a point twenty yards to their right – his lantern only the dimmest glow in the blowing snow – and then he leads Evans out into the maze of seracs, ice pinnacles, and pressure ridges, following the periodic smears of blood on the ice. He knows that a delay of even a few minutes will be enough to blow snow over the faint trail. The captain doesn’t even bother to remove the pistol from the pocket of his greatcoat.

Less than a hundred yards out, just where the lanterns of the men on the deck of HMS Terror become invisible, Crozier reaches a pressure ridge – one of those great heaps of ice thrown up by the ice plates grinding and surging against each other beneath the surface. For two winters in the ice now, Crozier and the other men of the late Sir John Franklin’s expedition have watched these pressure ridges appear as if by magic, rise with a great rumbling and tearing sound, and then extend themselves across the surface of the frozen sea, sometimes moving faster than a man can run.

This ridge is at least thirty feet high, a great vertical rubble of ice boulders each at least as large as a hansom cab.

Crozier walks along the ridge, extending his lantern as high as he can. Hodgson’s lantern is no longer visible to the west. Nowhere around Terror is the view simple any longer. Everywhere the snow seracs, drifts, pressure ridges, and ice pinnacles block one’s line of sight. There is one great ice mountain in the mile separating Terror and Erebus and half a dozen more in sight on a moonlit night.

But no icebergs here tonight, only this three-storey-tall pressure ridge.

“There!” shouts Crozier over the wind. Evans steps closer, his Baker Rifle raised.

A smear of black blood on the white wall of ice. The thing had carried William Strong up this small mountain of icy rubble, taking an almost vertical route.

Crozier begins climbing, holding the lantern in his right hand while he searches with his mittened free hand, trying to find cracks and crevices for his frozen fingers and already icy boots. He hadn’t taken time to put on his pair of boots in which Jopson had driven long nails through the soles, giving traction on such ice surfaces, and now his ordinary seaman’s boots slip and skitter on the ice. But he finds more frozen blood twenty-five feet up, just below the ice-jumbled summit of the pressure ridge, so Crozier holds the lantern steady with his right hand while kicking against a tilting ice slab with his left leg and leveraging himself up to the top, the wool of his greatcoat rasping against his back. The captain can’t feel his nose and his fingers are also numb.

“Captain,” calls Evans from the darkness below, “do you want me to come up?”

Crozier is panting too hard to speak for a second, but when he gets his wind back, he calls down, “No… wait there.” He can see the faint glow of Hodgson’s lantern now to the northwest – that team isn’t within thirty yards of the pressure ridge yet.

Flailing for balance against the wind, leaning far to his right as the gale streams his comforter straight out to his left and threatens to topple him off his precarious perch, Crozier holds the lantern out over the south side of the pressure ridge.

The drop here is almost vertical for thirty-five feet. There is no sign of William Strong, no sign of black smears on the ice, no sign that anything living or dead has come this way. Crozier can’t imagine how anything could have found its way down that sheer ice face.

Shaking his head and realizing that his eyelashes are almost frozen to his cheeks, Crozier begins descending the way he’d come, twice almost falling onto the rising bayonets of ice before slip-sliding the last eight feet or so to the surface where Evans is waiting.

But Evans is gone.

The Baker Rifle lies in the snow, still at half-cock. There are no prints in the swirling snow, human or otherwise.

“Evans!” Captain Francis Rawdon Moira Crozier’s voice has been trained to command for thirty-five years and more. He can make it heard over a sou’westerly gale or while a ship is white-foaming its way through the Strait of Magellan in an ice storm. Now he puts every bit of volume he can muster into the shout. “Evans!”

No answer except the howl of the wind.

Crozier lifts the Baker Rifle, checks the priming, and fires it into the air. The crack sounds muffled even to him, but he sees Hodgson’s lantern suddenly turn toward him and three more lanterns become dimly visible on the ice from the direction of Terror.

Something roars not twenty feet from him. It could be the wind finding a new route through or around an icy serac or pinnacle, but Crozier knows that it isn’t.

He sets the lantern down, fumbles in his pocket, pulls the pistol out, tugs off his mitten with his teeth, and, with just a thin woolen glove between his flesh and the metal trigger, holds the useless weapon in front of him.

“Come on, God-damn your eyes!” Crozier screams. “Come out and try me instead of a boy, you hairy arse-licking rat-fucking piss-drinking spawn of a poxy Highgate whore!”

There is no answer except the howl of the wind.
