Chapter Four - Latitude 58° 35′ N

The Board at Trinity House received the report with due concern, though not, perhaps, with due haste. A formal inquiry was drafted, then postponed. A replacement was suggested, then declined. The Admiralty, already uneasy about growing merchant traffic along the Danish corridor, applied pressure: the route was too important to leave unwatched, even for a fortnight. But volunteers were not forthcoming. The story of Gray’s disappearance, cloaked in rumour, embroidered by sailors with each retelling, did not lend itself to eager successors. Men at sea are a superstitious breed, and the idea of a station lit but uninhabited, burning through storms with no hand at the helm, unsettled more than it intrigued.

It was through informal correspondence, perhaps passed along a naval quartermaster’s desk or mentioned in one of Portsmouth’s quieter drawing rooms, that the vacancy came to the attention of one Mr Nathaniel Harrow. He had not been looking for employment, but for something altogether rarer: an opportunity to observe, uninterrupted and unrestrained.

Nathaniel Harrow was born to a family that would have much preferred a solicitor. The Harrows of Derbyshire were neither landed nor titled, but they had been quietly prosperous since the reign of George III, thanks to a string of favourable marriages and a knack for linen. His father, Edwin Harrow, had once entertained ambitions of Parliament, and was sorely disappointed when his youngest son declared an interest not in law or trade, but in celestial mechanics. Nathaniel, to his credit, made the announcement with a telescope already in hand.

He was schooled at Rugby, where he earned a reputation for precision and poor eyesight, then took a scholarship at Trinity College, Cambridge. There, he distinguished himself in mathematics, natural philosophy, and the unfortunate habit of attending chapel with logarithmic tables tucked into his Psalter. He graduated with honours, and promptly set about alienating his tutors by insisting, in a modestly circulated paper, that Greenwich Mean Time was “at best, an averaged lie.” His entry into the Royal Astronomical Society came not on account of pedigree - for he had none - but through a series of lectures delivered to naval cartographers, where his insights into longitude measurement earned grudging admiration and more than a few raised brows. He was meticulous, dogged, and wholly incapable of pretending not to notice patterns where others saw only drift. But it was not his formal training that would define him.

It was not long before Harrow’s inquiries began to skirt the acceptable. In private notes, he described “perceived inconsistencies” in sidereal time observations across northern latitudes. He referenced stars that appeared a fraction early, lunar phases that did not wholly agree with the almanacs. He proposed, in a letter to a fellow member of the Society, that “time may well possess regional preferences.” The letter was never formally replied to.

By 1852, Harrow’s invitations to speak had dwindled. He was not exactly ostracised, but neither was he embraced. He had become - in the polite parlance of the scientific elite - interesting. Which is to say: no longer entirely useful. It was at this precise moment, while tending to rusted sextants in a Portsmouth classroom, that he heard of a vacancy. A lighthouse. Remote. Unclaimed. Light still functional. Keeper… missing. And most importantly - latitude 58° 35' N. Harrow made discreet enquiries. A rumour, passed through a former midshipman, then a dockyard clerk, then a former instructor at the Royal Naval College. Enough fragments aligned to make it plausible. Within the week, he drafted a letter of interest to Trinity House. Days passed. Then a week. Then two.

When an envelope finally arrived, it bore not the seal of Trinity House, but the familiar crest of his family’s estate in Somerset. The Admiralty, it seemed, had sent word not to him, but to his father - Admiral Edwin Harrow, retired, and still a fixture in certain naval circles.

“Going to a lighthouse?” his father wrote. “This borders lunacy. If you must indulge your whims, let them be within arm’s reach of reason, not somewhere north of Aberdeen with a lantern and a tin of biscuits!”

Nathaniel did not reply. Not directly. But a few days later, he penned a letter to his mother. It read:

To Mrs. Aurelia Harrow, Mayfair, London
16 July, 1852

Dearest Mother,

I write en route to my new station, one I doubt will receive Father’s blessing, though I trust you’ll understand the pull it holds for me. A lighthouse, situated upon a bleak and sea-battered rock of some minor consequence - though I am told its lantern is of vital importance to a new mercantile corridor. You may console yourself with the knowledge that it is not war, nor exile, but observation that draws me there. I shall be alone, yes, but not unaccompanied - the stars are faithful companions, requiring neither flattery nor conversation.

My instruments have arrived intact. The chronometer remains sound.

You will no doubt hear from the Society in due course. Until then, do not be alarmed if correspondence is irregular; I shall write when fog and radio silence permit.

Yours in affection (and, I admit, no small curiosity),
Nathaniel

P.S. In my haste this morning, I nearly forgot to pin the small silver comet you gave me last Christmas - the one with the dent from Bath. Consider it my personal Polaris: a reminder that even comets can find their way.

Arrangements were made with neither haste nor ceremony. The Royal Astronomical Society, while initially perplexed by Harrow’s intentions, did not object. His leave of absence was approved with the quiet understanding that eccentricity was often the cost of brilliance. A small parcel of instruments - quadrant, sextant, barograph, and the prized marine chronometer presented to him two winters prior was packed under his supervision, each piece checked and re-checked as though preparing not for a voyage, but for a duel. His departure from Portsmouth passed unremarked. A hired carriage conveyed him to Lowestoft, and from there, a modest naval cutter bore him east into the churn and chop of the North Sea. The vessel’s commander, a taciturn man of few syllables, offered no opinion on Harrow’s suitability, though his silence was eloquent enough. Harrow, lost in thought and marginalia, scarcely noticed. He was already mapping constellations onto the shifting clouds above.

The Sister Mercy made landfall beneath a sky the colour of old parchment. The sea, for once, had relinquished its usual violence and lay dull and heavy, like pewter left to tarnish. A light mist hovered over the water - not quite fog, but enough to blur the horizon and unmoor one’s sense of direction. Above it all, the lighthouse stood like a disapproving sentinel, its lantern still glowing, faint but unyielding, as though unaware its keeper had long since vanished. Harrow emerged from the lower deck dressed in a practical wool coat, his frame lean and angular against the greying light. He wore no hat, a decision he would regret, and clutched his satchel like a man unsure whether he had packed wisely or simply desperately. The cutter’s commander, a man whose name Harrow never learned, offered no farewell, only a grunt and a nod toward the landing steps. Two sailors assisted in lowering the crates: one containing food provisions, one his instruments, and a third - marked Handle with precision - held the chronometer. They worked quickly, with the air of men eager to be elsewhere. One, after glancing upward at the ever-burning lantern, muttered something in Gaelic and refused to step off the gangplank.

“You’ll be needing to oil the winch cables,” said the other without looking up. “Salt’s eaten the pulleys near through. Last fellow left them in a state.” It was the only direct reference made to Finnegan Gray.

No one offered a hand. Harrow made the short climb to the platform alone, balancing awkwardly as the wind picked up - not a gale, not yet, but enough to remind him of the sea’s indifference. He paused at the threshold of the gate, a rusting iron thing that squealed in protest when pushed open. For a moment, he thought he heard something else beneath the groan, a distant rhythmic knock, faint and low, like a loose beam tapping in the wind. Once the last crate was hoisted over the lip of the dock, the sailors retreated and the cutter pulled away into the haze, leaving Harrow alone with the sound of gulls, the slap of waves against stone, and the knowledge that no other soul stood with him on Grimleigh Rock. He turned to face the tower, adjusting his spectacles, and exhaled once, sharply.

“Well,” he said to no one, “let’s take a measure of time.”

The door yielded with surprising ease. A stiff turn of the key left beneath a stone (as the quartermaster had suggested) and a solid push brought Nathaniel Harrow into the main vestibule of Grimleigh Lighthouse. The air inside was cool and dry, faintly mineral, with a trace of paraffin and salt. He paused, letting his eyes adjust to the gloom. It was curiously tidy. The floor had been scrubbed. Shelves, though sparse, were well organised: a row of oil tins, spare wick reels, a single logbook bound in dark leather, its spine labelled in a cramped but steady hand. A pair of boots had been left by the wall, aligned neatly beneath a peg that held a long wool coat - worn, but brushed clean. Even the fire grate was empty of ash, swept and reset, as though the keeper had merely stepped out for air. No signs of struggle, no disarray, not even the bitter trace of abandonment. Only silence, and the distant gulls.

Harrow moved through the quarters with measured steps, notebook in hand. The bunkroom was small but orderly. One narrow bed, coverlet pulled tight, pillow indented only slightly. A shaving mirror leaned against the sill, angled outwards toward the sea - an odd, almost personal gesture, as though the previous occupant had found solace in watching the horizon. A few books remained on the bedside shelf: Prayers for Mariners, The Navigation of Northern Waters, a well-thumbed edition of Pliny’s Natural History. The last page was dog-eared. The kitchen was equally austere: a single tin plate in the drying rack. A kettle, polished, rested beside a flint striker and an unopened tin of tea. Harrow noted the absence of mould or decay. The place had been maintained, almost preserved, as though time itself had paused the moment the keeper departed. He jotted down a few remarks:

"Interior condition: sound. Signs of habitation remarkably intact. Austerity admirable. Psychological profile of former keeper to be deduced from objects left behind. Notably: no mirror above washbasin. Either humble… or afraid."

By the time his belongings were unpacked the hour was well past three. The lantern room would require inspection, but not yet. Harrow, though often forgetful of meals, prepared a small supper of hard bread and cheese, eaten cold beside the signal ledger, and accompanied - perhaps indulgently - by a jar of quince preserve and a modest flask of claret wrapped in felt. As the wind pressed in soft pulses against the windowpanes and the lantern cast its slow-turning amber glow across the chamber walls, Harrow reached into the velvet-lined compartment of his satchel and withdrew the marine chronometer. It was still swaddled in its oiled cloth, meticulously folded, the brass casing faintly perfumed with cedar, salt, and a memory of workshops long shuttered. He placed the instrument gently upon the table and opened the lid. The enamelled dial caught the lamplight - pale, precise, inscrutable. Harrow leaned in, elbows beside his plate, listening.

Tick. Tick. Tick.

And then, a breath’s breadth, or less, a pause so brief it might have been imagined. A stumble in the tempo. Not silence, but uncertainty. A hesitation not in the mechanism, but somewhere subtler, as if time itself had faltered mid-step and, finding no one watching, continued on. He exhaled, finished the last of his bread, and dabbed his fingers with a handkerchief worn soft from habitual folding.

“Too much sea air already,” he murmured, though whether it was addressed to the chronometer, the supper, or himself was left unresolved. He checked the time against the wall-mounted regulator. A one-second discrepancy. He made a note to recalibrate tomorrow - assuming, of course, that tomorrow arrived in sequence. And just as he turned away, the dial’s second hand gave a tremor, then realigned itself, as though unsure which direction it had meant to move.
