It had been seven years ago almost to the week, the Southern-Hemispheric spring month of November of 1840, when Crozier had arrived in Van Diemen’s Land south of Australia in these very ships – Erebus and Terror – on the way to Antarctica. The expedition had been under the command of Crozier’s friend, although always his social superior, Captain James Ross. They had stopped at Hobart Town to finish their provisioning before heading into antarctic waters, and the governor of that penal island, Sir John Franklin, insisted that the two younger officers – Captain Ross and Commander Crozier – stay at Government House during their visit.

It had been an enchanting time and – to Crozier – a romantically fatal one.

The inspection of the expedition’s ships had occurred on the second day of the visit – the ships were clean, refitted, almost fully provisioned, their young crews not yet bearded or made haggard by the two winters in the antarctic ice to come – and while Captain Ross personally hosted Governor Sir John and Lady Jane Franklin, Crozier had found himself escorting the governor’s niece, the dark-haired and bright-eyed young Sophia Cracroft. He had fallen in love on that day and had carried that blossoming love into the darkness of the next two southern winters, where it had bloomed into an obsession.

The long dinners under the servant-turned fans of the governor’s house were filled with lively conversation. Governor Franklin was a worn-out man in his midfifties, dispirited by the lack of recognition of his accomplishments and dispirited further by the opposition of the local press, wealthy landowners, and bureaucrats during his third year in Van Diemen’s Land, but both he and his wife, Lady Jane, had come alive during this visit by their Discovery Service countrymen and, as Sir John liked to address them, his “fellow explorers.”

Sophia Cracroft, on the other hand, showed no signs of unhappiness. She was witty, alive, vivacious, sometimes shocking in her comments and boldness – even more so than her controversial aunt, the Lady Jane – and young and beautiful and seemingly interested in every aspect of the forty-four-year-old bachelor Commander Francis Crozier’s opinions, life, and sundry thoughts. She laughed at all of Crozier’s initially hesitant jokes – he was not used to this level of society and strived to be on his best behaviour, drinking less than he had in years and that only wine – and she always answered his tentative bon mots with increasingly higher levels of wit. To Crozier, it was like learning tennis from a far better player. By the eighth and final day of their extended visit, Crozier felt the equal of any proper Englishman – a gentleman born in Ireland, yes, but one who had made his own way and had also lived an interesting and exciting life, the equal of any man – and the superior of most men in Miss Cracroft’s amazing blue eyes.

When HMSs Erebus and Terror left the Hobart Town harbour, Crozier was still calling Sophia “Miss Cracroft,” but there was no denying the secret connections they had made: the secret glances, the companionable silences, the shared jokes and private moments alone. Crozier knew that he was in love for the first time in a life whose “romance” had consisted of dockyard doxies’ cribs, back-alley knee-wobblers, some native girls doing the deed for trinkets, and a few overpriced nights out in gentlemen’s whorehouses in London. All that was behind him now.

Francis Crozier now understood that the most desirable and erotic thing a woman could wear were the many modest layers such as Sophia Cracroft wore to dinner in the governor’s house, enough silken fabric to conceal the lines of her body, allowing a man to concentrate on the exciting loveliness of her wit.

Then followed almost two years of pack ice, glimpsing Antarctica, the stink of penguin rookeries, naming two distant, smoking volcanoes after their tired ships, darkness, spring, the threat of being frozen in, finding and fighting their way out by sail only through a sea now named after James Ross, and finally the rough Southern Sea passage and the return to Hobart Town on the island of eighteen thousand prisoners and one very unhappy governor. This time there was no inspection of Erebus and Terror; they stank too much of grease and cooking and sweat and fatigue. The boys who had sailed south were now mostly hollow-eyed and bearded men who would not sign up for future Discovery Service expeditions. Everyone except HMS Terror’s commander was eager to return to England.

Francis Crozier was eager only to see Sophia Cracroft again.

He took another drink of whiskey. Above him, barely audible through the deck and snow, the ship’s bell rang six bells. Three a.m.

The men were sorry when Sir John had been killed five months ago – most of them because they knew that the promise of ten sovereigns per man and a second advance-pay bonus had died with the paunchy, bald old man – but little actually changed after Franklin’s death. Commander Fitzjames was now acknowledged as the captain of Erebus that he’d always been in reality. Lieutenant Le Vesconte, gold tooth flashing when he smiled, his arm in a sling, took Graham Gore’s place in the hierarchy of command with no visible ripple of disruption. Captain Francis Crozier now assumed the rank of expedition commander, but with the expedition frozen in the ice, there was little he could do differently now from what Franklin would have done.

One thing Crozier did almost immediately was ship more than five tons of supplies across the ice to a point not far from the Ross cairn on King William Land. They were now fairly certain it was an island because Crozier had sent out sledge parties – monster bear be damned – to scout the area. Crozier himself went along on half a dozen of these early sledge parties, helping to smash easier, or at least less impossible, paths through the pressure ridges and iceberg barrier along the shore. They brought extra winter slops, tents, lumber for future cabins, casks of dried foods and hundreds of cans of the tinned foods, as well as lightning rods – even brass bed rods from Sir John’s appropriated cabin to be fashioned into lightning rods – and the essentials of what both crews would need if the ships had to be abandoned suddenly in the midst of the next winter.

Four men had been lost to the creature on the ice before winter returned, two from one tent during one of Crozier’s trips, but what stopped the transfer sledge trips in mid-August was a return of the severe lightning and thick fog. For more than three weeks both ships sat in the midst of the fog, suffered the lightning to strike them, and only the briefest ice outings – hunting parties mostly, a few fire-hole teams – were allowed. By the time the freakish fog and lightning had passed, it was early September, and the cold and snow had begun again.

Crozier then resumed sending cache-supply sledge parties to King William Land despite the terrible weather, but when Second Master Giles MacBean and a seaman were killed just a few yards ahead of the three sledges – the deaths unseen because of the blowing snow but their last screams all too audible to the other men and to their officer, Second Lieutenant Hodgson – Crozier “temporarily” suspended the supply trips. The suspension had now lasted two months, and by the first of November no sane crewman wanted to volunteer for an eight- to ten-day sledge trip in the dark.

The captain knew that he should have cached at least ten tons of supplies on the shore rather than the five tons he’d hauled there. The problem was – as he and a sledge party had learned the night the creature had ripped through a tent near the captain’s and would have carried off seaman George Kinnaird and John Bates if they had not run for their lives – any campsite on that low, windswept gravel-and-ice spit of land was not defensible. Aboard the ships, as long as they lasted, the hulls and raised deck acted as a wall of sorts, turning each ship into a kind of fort. Out on the gravel and in tents, no matter how tightly clustered, it would take at least twenty armed men watching day and night to guard the perimeter, and even then the thing could be among them before guards could react. Everyone who had sledged to King William Land and camped out there on the ice knew this. And as the nights grew longer, the fear of those unprotected hours in the tents – like the arctic cold itself – seeped deeper into the men.
