Ren hesitated. "Some of it, maybe. I don't fully understand where it came from, honestly. And that scares me a little, if I'm being truthful with you."Dorothy nodded slowly, like she'd suspected as much. "Be careful with that notebook," she said. "This university has a long memory when it wants one, and a very short one when it's convenient. I'd hate to see you get caught between the two, especially so early in your time here."Ren didn't fully understand the warning at the time; she would understand it completely by the end of the week.Outside Wentworth Hall, on her walk back toward her afternoon class, Ren stopped without quite meaning to. She stood at the base of the front steps—the same steps from the photograph, worn smooth now by fifty more years of students who had no idea what had once happened there. She tried to picture him: a young man in a jacket too big for him, standing right about where she was standing now, hopeful about something he had no way of knowing would be taken from him.She thought about her grandmother's voice on the phone the night before: He never much liked talking about it, so I got used to not asking. Fifty years was a long time to carry something quietly, she thought—longer than her own life so far, twice over and then some. She didn't know yet that she was about to be asked to carry it, too, in ways she couldn't yet imagine.That same afternoon, across campus, Sterling Doyle sat in the graduate lounge, laptop open, doing research of his own. He had been unable to stop thinking about Tuesday's class, about the spiral, about the way Ridgeway's hands had trembled at the chalkboard—a look that Sterling had never once seen from his mentor in three years of working beside him. He told himself it was academic curiosity; it wasn't only that.He searched Ren's name. Nothing unusual came up: just a small town, a small high school, a modest academic record—the kind of file that told him nothing about a girl who could apparently reframe fifty-year-old mathematics on command. He searched for the spiral technique itself, phrase after phrase, trying to find where such an unconventional approach could have possibly come from. Most freshmen didn't invent original number theory on the spot; that much he was certain of. Someone must have taught her, somewhere, somehow.A fellow graduate student, a soft-spoken man named Aaron who shared the lounge's back table, glanced over at one point. "You've been at that for two hours," Aaron said. "What's going on?""Nothing," Sterling said too quickly. "Just double-checking something for Ridgeway.""You sure? You've got that look.""What look?""The one you get right before you do something you're going to regret," Aaron said, only half-joking, and went back to his own work.Sterling didn't answer. He thought of the notebook, the one Ridgeway had told him privately to keep an eye on without fully explaining why. He decided it was time to look closer, telling himself—as people often do right before crossing a line—that he was simply being thorough.He found Ren in the library two days later, sitting alone near the periodicals, the leather notebook open in front of her. He approached quietly, the way a person approaches something they don't want to spook.
