The first missed day arrived without warning, three years and one impossible lifetime after the very first unremarked lateness that had once cost Thomas a single anxious hour back in the thaw.
He checked the phone that evening out of the same long habit that had governed every evening since the anomaly first stranded him, and found, for the first time in longer than he could properly remember, nothing waiting at all. No green text. No ordinary, comfortable account of a garage roof or a neighbor's dog. Simply silence, where four years of unbroken daily comfort had always, reliably, been.
He told himself it meant nothing. A missed day, once, after years of perfect regularity, was hardly the same as a pattern — could be anything, a busy evening on his mother's end, some ordinary interruption in a life he could no longer properly picture the shape of.
The letter arrived the following evening instead, a full day late, warm and ordinary and entirely unaware, as always, of the gap that had preceded it.
Sorry I didn't get to write yesterday — it was a madhouse around here, Sarah had a school thing that ran late and I completely lost track of the evening. Anyway, tell me how the new project's going…
Thomas read it with a cold, sinking recognition, understanding, even before Victoria arrived to read the trouble in his face, exactly what he was looking at.
"It's happening again," he said, when she settled beside him. "Not the memory this time. The connection itself. I went years without a single missed day, Victoria — years — and now, twice in the space of a month, an evening's simply gone missing before the letter finally, belatedly arrives."
Victoria's expression, absorbing the news, carried the particular grave stillness she reserved for confirmations of a fear they'd both been quietly expecting. "The anchor."
"I checked it before I found you. Nine." Thomas said the number plainly, without the raw shock it might once have produced, though the plain fact of it still settled heavy in his chest. "It's fallen faster this month than in any month before it. I don't know if that's the plague's own weight somehow adding to the deviation, or Sarah, or simply the accumulated cost of everything we've built these past four years finally catching up all at once. I only know the number keeps dropping, and now the letters are dropping alongside it."
"What do you think happens next?"
"I think, eventually, daily stops being reliable at all. I think we're watching the beginning of exactly what the relay warned us about, all those months ago. A cascade. Not a single dramatic ending, but a slow, accumulating unraveling, one missed evening at a time, until the missed evenings outnumber the reliable ones." Thomas felt the particular exhausted clarity of a man finally naming a fear he'd spent months circling without quite landing on directly. "I don't know how much longer I have where the letters still arrive daily, Victoria. I don't know how much longer I have at all."
Victoria took his hand, her grip steady despite the tremor he could feel beneath it, the same quiet, determined strength she'd offered him through every difficult reckoning of the past difficult year. "Then we keep doing exactly what we've been doing. We record it. We build the days. We let neither the fear nor the uncertainty stop us from living as fully as the time we do have allows." She met his eyes, and there was real love in her steady, unflinching gaze, undimmed by any of the accumulating grief. "I would rather have four years of daily letters and whatever's coming next, Thomas, than never to have had you at all. I want that said plainly, tonight, while the fear is fresh enough that I think you need to hear it plainly."
Thomas pulled her close, the cold winter evening settling around them both, and found, holding her, that the fear — vast and uncertain and growing though it was — remained, for now at least, considerably smaller than the plain, sufficient fact of her continued presence beside him, steady through every difficult year they'd built together, however many more such years the falling numbers ultimately allowed them to share.
