Kinloch, Scottish Highlands — Present Day

Kinloch, Scottish Highlands — Present Day.

A Wednesday morning in September.

DI Melissa Steed had been awake since five, and had told herself, driving in through a mist still lying low and undecided over the harbour, that this was simply an early callout, unremarkable in every particular except its timing, the kind of thing that happened perhaps twice a month to any detective inspector working a small Highland station. A guest found unresponsive in a hotel room. A locked door. A heart, presumably, that had simply stopped, the way hearts sometimes did, in men in their fifties who worked too hard and slept too little and had spent the previous evening, according to the hotel’s own function room booking, delivering a keynote speech to a room full of people who would, by lunchtime, be reading about his death instead.

She had left her own flat quietly, careful not to wake Callum, who had stayed over more nights than not across the last two months, a small, ordinary domesticity neither of them had named yet but both, she suspected, understood exactly the shape of. She had thought, driving in, about how strange it still felt, after everything the previous winter had cost them both, to have arrived at something this settled — a man asleep in her bed, a life that had, against every reasonable expectation either of them had once carried about the other, quietly become something worth protecting rather than simply surviving.

She had not expected, walking into that room forty minutes later, to feel the specific, cold vertigo of recognising something she had no business recognising at all.

The Kinloch Arms sat at the top of the high street, a converted coaching inn that had, over the decades, hosted everything from wedding receptions to the occasional minor royal visit, and Room 14 — a corner room, the hotel’s best, booked under the name of the Scottish Parliament’s cross-party group on coastal infrastructure — looked, at first glance, exactly like the ordinary, tasteful hotel room it was meant to be. A four-poster bed, unmade on one side only. A laptop open on the small writing desk, its screen gone dark. A room service tray, a single glass with the dregs of what the scene photographer would later confirm was an unremarkable single malt.

And Gareth Pugh, Member of the Scottish Parliament for the wider Highland constituency, lying on the floor beside the bed, one arm flung out toward the window as though he’d been reaching for something in his final seconds that nobody in the room could now identify.

Melissa recognised him, distantly, the way she recognised most public figures whose faces occasionally crossed a news bulletin without ever properly registering as belonging to an actual, specific life — a heavyset man in his mid-fifties, greying, the kind of ordinary, competent face that photographed well enough for a campaign leaflet without ever quite becoming memorable on its own. She had voted for him once, she thought, standing over his body, though she couldn’t now recall with any confidence which election, or what he’d actually promised that had earned her mark on the ballot paper.

‘Doctor’s on scene already,’ the young constable at the door said, as Melissa signed the log and pulled on a pair of gloves. ‘Says it looks consistent with a cardiac event. No signs of forced entry, door was on the chain from the inside, hotel had to use their own master key once housekeeping couldn’t rouse him for the room service he’d ordered and never touched.’

‘Anyone touch anything before the doctor arrived.’

‘Housekeeping opened the door, saw him, backed straight out and called it in. I don’t think anyone’s been within six feet of him since.’

Melissa nodded, and moved into the room properly, cataloguing it with methodical attention she’d learned, across a long career, to bring to every scene regardless of how straightforward it initially looked — because straightforward scenes had a way, in her experience, of turning less straightforward the longer you were willing to actually look at them.

She crouched beside the body first, out of professional habit rather than any expectation of finding something the doctor had missed, and found nothing that contradicted the initial assessment — a man in his fifties, unremarkable physical condition beyond what she’d expect of anyone who spent his working life behind a desk and in front of cameras, no visible injury, no sign of struggle. She stood, and turned to the window, and it was there, examining the room’s other features with the same unhurried thoroughness, that she saw it.

Carved into the wooden window frame, low, near the sill, small enough that housekeeping would never have noticed it in years of routine cleaning, was a symbol — three interlocking lines, forming a shape that was not quite a triangle and not quite anything else Melissa could immediately name, the wood around it darkened slightly with age in a way that suggested it had not been carved that morning, or even that year.

She stood very still, looking at it, and felt the recognition of a detective’s mind reaching for a memory it could not yet properly place, the sensation of having seen this exact shape somewhere before, in a context that had nothing to do with hotel rooms or cardiac events or Members of the Scottish Parliament.

‘Get me a torch,’ she said, to the constable still standing at the door. ‘And I want this window frame photographed properly, close up, before anyone in this room touches anything else.’

She found the match four hours later, back at the station, going through the archived case file from 1987 with a thoroughness she understood, doing it, was very possibly excessive for what had, so far, been ruled a natural death — but the symbol had not left her mind since the moment she’d first seen it, and Melissa had learned, across a long career, to trust exactly this kind of restless, unexplained persistence rather than talk herself out of it.

The archive room smelled the way it always did, dust and old paper and the particular mustiness of documents that had sat undisturbed in cardboard boxes for decades, and Melissa worked through the 1987 file’s contents methodically, laying each photograph out on the long table in the order the original investigation had catalogued them, the same discipline she’d have brought to any resourced modern case, however little modern resource this particular archive had ever been afforded. She was aware, doing it, of the specific strangeness of handling documents that predated her own birth by two years — evidence of a childhood tragedy that had shaped this entire town before she’d ever drawn breath in it, and that she had, across her whole career here, always understood as history rather than as anything still capable of reaching directly into her own present.

The photograph was in the file’s third box, a black-and-white print taken by the original 1987 investigation team, cataloguing the shore path near the old asylum ruin in the days after the disappearance — a general survey shot, unremarkable, the kind of documentation photograph that existed in every case file by the dozen and had never, so far as the archived notes suggested, been considered significant enough to warrant closer examination.

But there, in the corner of the frame, carved into a fence post that had long since rotted away and been replaced, was the same symbol. Three interlocking lines, the same not-quite-triangle shape, photographed thirty-seven years before Gareth Pugh had died in a locked hotel room with his arm flung out toward a window carrying an identical mark.

Melissa sat with the two photographs side by side for a long time, the station around her going quiet as the evening shift thinned out, and realised that she was no longer investigating a straightforward cardiac death at all.

She called Reyes at home that evening, understanding, dialling the number, that this particular call was going to change the shape of her week considerably.

‘I need you to look at something,’ she said, once he’d answered. ‘Gareth Pugh. I don’t think it was natural causes, sir, and I think the reason I don’t think that is going to sound stranger than anything I’ve brought you before.’

Reyes was quiet for a moment, and Melissa heard, in the silence, a man bracing himself for exactly the kind of complication his career had apparently decided, over the last year, to specialise in providing him. ‘Go on.’

‘There’s a symbol carved into the window frame of his hotel room. I’ve matched it to a photograph from the original 1987 case file — the same mark, carved into a fence post near the disappearance site, thirty-seven years ago.’ Melissa kept her voice level, understanding exactly how the sentence was going to land. ‘I don’t yet know what it means. I know it’s not a coincidence, sir. Nothing about this case has been a coincidence yet, and I don’t believe this is going to be the exception.’

‘Pugh cast the deciding vote on the harbour development,’ Reyes said, slowly, working through it aloud. ‘The one clearing the way to excavate the old site.’

‘I know. I’ve been sitting with that connection all afternoon.’

‘Then I want the post-mortem redone, properly, with a pathologist who understands exactly what we might be looking for rather than one working from an assumption of natural causes.’ Reyes’s voice had gone careful, focused, the specific tone Melissa had come to associate with him across the last year whenever a case’s true shape finally began revealing itself. ‘And Melissa — I want you to consider, before this goes any further, whether you’re the right officer to lead it. Not because of your competence. Because I remember, from your own personnel file, that your father worked the docks in this town his whole life, and I don’t yet know how deep this particular thread runs, and I’d rather ask you the difficult question now than discover the answer to it halfway through an investigation neither of us can afford to compromise.’

Melissa sat with that for a long moment, understanding, even as the question landed, that some part of her had already been asking herself the same thing since the moment she’d first seen the symbol on that window frame — a small, cold recognition she hadn’t yet let herself properly examine, the specific unease of a memory sitting just beyond reach, waiting.

‘I want to lead it,’ she said, finally. ‘I think I need to, sir, though I can’t yet fully explain why.’

‘Then find out why, Melissa. Properly, before this goes any further. I’d rather you understood your own stake in this before it understood you.’

She drove home slowly that night, the mist still hanging low over the harbour, and found herself, pulling up outside her own flat, thinking not of Gareth Pugh at all, but of a box in her mother’s loft she had not opened since she was fifteen years old — a box she had told herself, every year for two decades, she would finally go through properly, and had, every year, found some reason not to.

She sat in her car for a long while before going inside, understanding, with a cold certainty she could not yet fully justify, that Reyes’s question had found exactly the thread it was meant to find, and that whatever waited in that box was very possibly no longer a thing she had the luxury of continuing to postpone.

Callum was still awake when she finally came in, sitting up with a book he wasn’t really reading, and looked at her face properly before she’d said a single word about the day. ‘Bad one.’

‘Strange one. I’m not certain yet whether strange and bad turn out to be the same thing this time.’ She sat down beside him, suddenly aware of how tired she actually was, the particular bone-deep exhaustion that had nothing to do with the hours she’d worked and everything to do with the weight of a case that had, in a single afternoon, reached backward and touched something she’d spent her whole adult life not looking at too closely. ‘I think I need to ask my mother about my father tomorrow. Properly, for the first time in longer than I want to admit.’

Callum didn’t ask why, watching her with the particular patient attention she’d come to rely on more than she’d ever expected to, across the strange, careful year that had brought them to exactly this quiet, ordinary evening. ‘Do you want company for that.’

‘I don’t know yet.’ She leaned into him, grateful, for the first time all day, to simply not be alone with it. ‘I think I need to find out what’s actually in that box before I know what kind of company I’m even going to need.’
