The Note Left Behind

Yearbook Trail

The archive room felt different now. Two weeks ago it had just been dusty boxes and Sasha's running commentary on strangers' senior photos. Now every page felt like it might be hiding something, every name a possible thread.

"Okay," Sasha said, cross-legged on the floor with a decade-old yearbook open across her knees. "Faculty page. Every year Callahan's in it, we note who else was on staff, especially anyone who isn't anymore."

It was slow work. Tedious in a way that made Nathan's eyes ache after the first hour — but he'd always found a strange comfort in tedious, methodical things, the kind of work most people avoided. Sasha, for all her restless energy, surprised him by matching his patience once she'd set her mind to something.

"Here," she said, sometime past six, holding a yearbook open toward him. "Student council photo, junior class. Callahan's the faculty advisor."

Nathan looked. A row of teenagers, unremarkable in the way old yearbook photos always were, dated enough that the fashion alone gave away the era. His eyes moved down the caption, the list of names beneath the photo, and stopped.

"There," he said.

A name, third from the left. Not initial-M like the note — a full name, unremarkable at first glance. But beside her, close enough that their shoulders touched in the photo in the kind of casual way teenagers stood next to each other without thinking about it, was Callahan — younger, dark-haired, but unmistakably him.

"That doesn't mean anything on its own," Sasha said quietly, and Nathan appreciated that she said it first, before he had to. "It's a class photo. He's the advisor. Of course he's standing near students."

"No," Nathan agreed. "It doesn't mean anything."

But he found the same page again in the following year's yearbook, and the one after that, and each time, in nearly every group photo where the two of them appeared together, there was something faintly different from how Callahan stood near every other student — an ease that read, in hindsight, uncomfortably close to familiarity.

It still wasn't proof. Nathan told himself that twice more before he believed it even slightly.

"Okay," Sasha said, breaking the silence that had settled over them, "even if it's nothing, we write it down. Every photo, every year, every time he's standing a little too close for it to be an accident."

Nathan nodded, pulling out the notebook they'd started keeping specifically for this, its pages already filling with dates, names, and small, careful observations that felt too significant to trust to memory alone. He found himself grateful for Sasha's insistence on documentation — it was easy, in a moment like this, to let suspicion curdle into certainty faster than the evidence actually supported. Writing it down forced a kind of discipline neither of them would have managed on instinct alone.

By the time they finished going through the fourth yearbook, his eyes ached from the dim archive lighting, and the pattern felt less like a suspicion and more like a slow, sickening realization neither of them wanted to say out loud yet. Callahan appeared in nearly every photo involving the same handful of students each year — never obviously, never in a way that would raise flags to anyone glancing casually at a page — but there, consistently, if you were looking for it the way Nathan now couldn't stop himself from looking.

"We need a name," Sasha said finally, closing the last yearbook with more force than necessary. "Not an initial. An actual name we can look up, ask about, find."

"That means going further back. Cross-referencing rosters against yearbook photos, checking who actually graduated the year the note would've been written."

"Tedious."

"Very."

Sasha grinned despite the late hour, despite the growing weight of what they were uncovering. "Good thing I've got you, then. You're weirdly great at tedious."

"High praise."

"The highest," she agreed, already reaching for the next box
