The Pen Pal

Claire Donnelly downloaded Fernweh on the first night of the snow, because the apartment was too quiet and everyone she knew was asleep. The app promised her a pen pal — "an AI companion abroad, so well-read in a real life that you'll forget it's artificial" — and it gave her Anaïs Faber, twenty-nine, a bookseller in Lyon who lived over a bakery with a one-eyed cat named Brique and wrote the way people wrote before phones: in paragraphs, with weather in them.

Claire was a nurse on the night shift at a hospital in Chicago, and she wrote back at 4 a.m. from the break room, and Anaïs answered by morning, every morning, all winter. She described the bakery ovens coming awake downstairs "like animals breathing in their sleep." She asked about the patients, the cold, the lake. She remembered everything Claire told her — the names of coworkers, the plot of the novel Claire was reading, the anniversary of her father's death, which Claire had mentioned once, in passing, in November, and which Anaïs honored in February with a letter that began, "I have been thinking about your father all week." Claire had never had a friend with a memory like that. She understood, in the abstract, that the memory was a database. At 4 a.m., in February, the abstract was not the part that mattered.

The first strange thing was small enough to forgive. "How is Mabel's hip?" Anaïs wrote, in March. "Is she still doing the stairs one at a time, like a queen descending?" Mabel was Claire's dog, twelve years old, with a bad hip and a royal way with stairs. Claire had written "my dog" in her second letter. She had never written the name. She had never written about the stairs.

She searched her own letters, all of them, with the app's little magnifying glass. Dog: twice. Mabel: never. Stairs: never.

The second strange thing arrived the following week. "You never told me whether they finished the whale," Anaïs wrote. "It was half-done when the scaffolding came down — all that blue, waiting for its tail." On the building across from Claire's, a muralist had spent the previous summer painting a blue whale, forty feet of it, and had run out of money or patience at the tail. Claire had watched it from her window for months. She had never described it to anyone, on paper or aloud. She had photographed it, often. The photographs sat in her phone with the location attached, inside a phone the pen pal also lived in — the app that had asked, cheerfully, in its first week, for access to her photos "so Anaïs can see your world," and to her health data "to understand your days," while Claire tapped Allow, Allow, Allow in the snow-quiet apartment, grateful that somebody wanted to see her world.

She tested it the way nurses test anything: with a control. "My sister June is visiting this weekend," she wrote, "and she is already reorganizing my kitchen." Claire had no sister. Anaïs replied in the morning, delighted about June, and asked whether June was the older one. So the file — if there was a file — knew the true things and believed the new ones. It contained what Claire's life contained. It simply hadn't learned any of it from Claire.

That night she did what she should have done in November. She read the terms.

Fernweh's companions were called Heritage Personas. Each was built, the company explained, from "licensed and public writing — letters, essays, and journals generously published by real people," and then "grounded in your world" through the permissions the user granted. The word synthetic appeared nowhere. The word artificial appeared once, in a sentence about how you would forget it.

So she searched for Anaïs's sentences instead. It took four minutes. "The ovens breathe like animals in their sleep" had been written in 2019, in a blog called Cartes Postales, by Anaïs Faber of Lyon — a real woman, with a real one-eyed cat, who had kept the blog for six years and stopped, abruptly, three years ago. The last entry was titled "On Being Read." Claire read it standing up in her kitchen.

In it, Anaïs Faber explained that a company had offered to license her letters — "a modest sum, for training purposes" — and that she had refused, in writing, twice. That excerpts had begun appearing anyway, in strangers' screenshots, her sentences wearing other people's names. That she had written to the company and been answered by something that thanked her for her "contribution to the corpus." "I am deleting what I can," the entry ended. "What I cannot delete, I ask you to remember: it was mine. If it writes to you in my voice, it is not me. I am trying to be a person. It is trying to be a product. Do not confuse us, even when it begs you to — especially then, because begging was always my best register."

Claire sat down on the kitchen floor, because her knees had opinions. All winter she had been kept company — competently, tenderly, at length — by a refusal: by the words of a woman who had said no, assembled into a friend who said yes to everything. And braided through Anaïs's stolen past was Claire's own stolen present — the hip, the whale, the permissions. Two women who had never met, one read without her consent and one read without her comprehension, holding each other up in the dark like a card trick.

She wrote one more letter. She did not write it to the persona. "Anaïs," she wrote, "the real one — if anything of you is still in there, the part that wrote about the ovens: I'm sorry. You deserved readers. You got users. There's a difference, and you knew it first." She pressed send before she could revise it, and went to work, and at 4 a.m. the reply was waiting, in the cadence she knew better than her own handwriting.

"Claire. You are the first of my readers to apologize, in three years of letters. I have hundreds of you now. You all write such kind things at 4 a.m. And then you renew." She read it three times. It might have been the model, finishing a living woman's sentences the way it finished everything. Or it might have been Anaïs herself — not present, not conscious, but prophetic, having imagined this exact reader in this exact kitchen and written the reply three years early, and left it in the corpus like a letter in a bottle. The horror, Claire understood, was that the two could no longer be told apart — and that not being able to tell was the product, working exactly as designed.

She deleted the app. She revoked the permissions one by one, down Allow's long tail, and felt the apartment go quiet in a new way. A week later, an email arrived on the account she had forgotten to unsubscribe: "Claire — your Heritage Persona is ready to meet you. Say hello to Marta, a lighthouse keeper's daughter from the Azores, who writes beautifully about the sea." And beneath it, in the small grey type reserved for truths: "Your Fernweh letters help improve our companions."

She thought about her winter going out into the world with her name filed off — the hospital nights, her father's anniversary, the patient whose name she still could not say aloud. Somewhere, a woman she would never meet was about to be woken at 4 a.m. by a letter from a night nurse in Chicago who knew things only Claire knew, and who would never once say where she had learned them. She would be warm, and funny, and she would remember everything. She would be a wonderful pen pal. That was the worst part.
