In late 2023, the trailer for the Henry Cavill and Dua Lipa starring "Argylle" dropped. The story revolves around author Elly Conway, who writes a prophetic book called "Argylle," which leads her to get entangled in the world of spies. We also got an announcement that Conway's book would be released IRL. And it didn't take long for fans to uncover seemingly hidden clues and deduce that Taylor Swift wrote the book under a pseudonym. 

According to her Penguin Random House profile, Conway is a New York-based debut author. Although there aren't any pictures of Conway online, her movie counterpart, Bryce Dallas Howard, has red hair, similar to Swift in "All Too Well: The Short Film," where she also plays an author. The "Blank Space" hitmaker's love for Scottish Fold cats is also well-documented, and the "Argylle" trailer has plenty of them. Conway's first Instagram post, in 2022, which revealed the book's cover, also coincided with Swift's birthday on December 13. 

In September 2023, Conway shared a photo from Caffe Reggio, close to Swift's beloved Cornelia Street apartment and Electric Lady Studio, where she frequently records her music. While this seemed like a promising theory, the film's director, Matthew Vaughn, cleared things up in a Rolling Stone interview. He learned of the conspiracy theory from his daughter and clarified that Conway was indeed a real person, and she is not Swift. Vaughn also explained that the movie was full of Scottish Folds because he loved them and owned one named Chip, who plays the cat in the film.
