Taylor Swift made an appearance on The Late Show with Stephen Colbert on Wednesday. They talked about navigating the conclusion of an era and even collaborated on ideas for a mystery novel. Colbert requested Swift to share her top five songs, with “All Too Well (10 Minute Version)” included in her selections. They also discussed Colbert’s future plans following his show’s end in May next year. Swift proposed that he might delve into podcasting, TikTok, and eventually pen a book. She imagined him developing a mystery thriller set in a house draped in ivy. Colbert enthusiastically jotted down notes as Swift wove a story involving a mistress, a ghost, and an enigmatic family legacy. Colbert assured Swift that he’d give her half the earnings if the book becomes a success.
