An 800-word, untitled short story, unofficially known as the Harry Potter prequel, was written by J. K. Rowling in 2008 as part of a charity auction event, for which it fetched £25,000. It was published as part of What's Your Story Postcard Collection.[1] The story recounts an encounter with Muggle police experienced by Sirius Black and James Potter, taking place before the events of the Harry Potter series. The manuscript was stolen in 2017, and has not been located as of 2024.
