Chapter 3: The Woman Who Remembers Everything

She finds me at the coffee shop on Court Street, the one that used to be a bodega that used to be a butcher shop, the palimpsest city doing its infinite-revision thing. I'm cataloging my latest observations—Subject #31 through #36, all within a four-block radius, the frequency accelerating in a way that suggests pattern, intention, something worse than random static—when she sits down across from me without asking.

"You can hear it too," she says. Statement, not question.

I close my notebook. "Hear what?"

"Don't." Her voice is sharp enough to cut glass. "I've been watching you for three days. I saw what you did at Underwater Studios. I saw you counter the signal."

She's maybe fifty, dressed in the kind of carefully assembled outfit that signals art-world money—vintage band t-shirt under an Isabel Marant blazer, the high-low costume that Brooklyn has turned into a uniform. But her eyes are wrong. Too aware. Like she's looking at multiple timelines simultaneously and finding all of them disappointing.

"Who are you?"

"Dr. Claudia Rosen. I used to work at DARPA. Before that, Bell Labs. Before that—" She stops, seems to recalibrate. "I've been studying the frequency for eleven years. You're the first person I've met who can perceive it without technological assistance."

The coffee shop's espresso machine hisses and screams. I catalog the sound automatically: steam release, approximately 8,000 hertz, nothing unusual, nothing that will make anyone forget their name.

"It's not natural," I say.

"No." Claudia pulls out a tablet, swipes through screens too fast for me to read. "It's a weapon. Or it was. Or it's becoming one—the tense is complicated when dealing with technology that may or may not be conscious."

My hands go to my temples, the gesture I've developed for when reality starts doing the thing where it stops making the kind of sense reality is supposed to make. "You're telling me the forgetting-sound is… what? Artificial intelligence? An algorithm?"

"I'm telling you it's a frequency that erases specific memories with increasing precision, that it's been escalating in New York for six months, that it's targeting people according to criteria I haven't decoded, and that you—" She leans forward. "You can stop it. Which means you're either the solution or you're part of the problem, and I haven't determined which yet."

Subject #37 happens at the counter. Young woman, mid-twenties, orders a latte and then forgets what she ordered between paying and receiving the cup. The barista looks annoyed—this happens a lot lately, I've noticed, the forgetting, people have started adapting to it the way you adapt to anything that happens enough times—and just hands her the drink.

I don't counter it. I'm watching Claudia watch me not counter it.

"You can't save everyone," she says.

"I'm not trying to save anyone. I'm trying to understand what's happening."

"Good." She closes the tablet. "Then you're ready."

"Ready for what?"

"To meet the only person in New York who's never forgotten anything. Not one second, not one image, not one conversation." Claudia stands. "She's been waiting for you. She says you're the one who's going to help us find the source."

"Who is she?"

"My daughter. And the reason the frequency exists in the first place." Claudia's face does something complicated—grief and guilt braided together, a double helix of regret. "I built the first prototype to help her. Hyperthymesia—she remembers everything, every moment of her life in perfect detail. I thought if I could selectively erase traumatic memories, I could give her peace."

The frequency hits. Loud, sustained, coming from everywhere and nowhere. The entire coffee shop empties out—not physically, but cognitively. Twenty people forget where they are simultaneously, faces going blank as fresh snow.

I stand up, start to counter-hum, but Claudia grabs my wrist.

"Don't. This is her. She's calling you."

"Your daughter is doing this?"

"No." Claudia's grip tightens. "Something else is. Something that learned from my prototype and became something I can't control. But Vera—my daughter—she can feel it. She says it has a center. A source. A place it's broadcasting from."

The frequency peaks and drops. The coffee shop population blinks back into confused awareness.

"Where?" I ask.

"Red Hook. An old radio tower. Vera says it's alive."

I should walk away. I should go home, take the Zoloft, forget I ever heard frequencies no one else can hear. Instead I say: "Take me to her."

Because the body knows before the brain knows.

And mine knows I'm already too deep to surface.
