A Study in Scarlet

A Study in Scarlet was one of the books written by Arthur Conan Doyle about Sherlock Holmes in universes where the character was purely fictional, such as Aziraphale's world. In the world in question, Aziraphale owned a first-edition copy of the book, as with all the works of Arthur Conan Doyle, which he had to replace after Jenny Everywhere spilled cocoa on them. After Jenny brought a “real” version of Holmes to Aziraphale's bookshop as an apology gift, the man himself briefly flicked through Aziraphale's new copy before replacing it on the shelf.
